Endocrine System Communication

Endocrine System Communication Clarify the significance of intercellular correspondence and depict the system in question. Intercellular correspondence is significant in light of the fact that it help the sensory system to prolong the drawn out procedure of development, improvement, or multiplication. The endocrine framework utilizes compound delegates to hand-off data and guidelines between cells. One of the instruments engaged with intercellular correspondence is know as immediate correspondence this correspondence is uncommon however is significant when it happens. This is when two cells of the same sort and the cells must be in broad physical contact. The cells are so close they work as one. Most of the correspondence is known as paracrine correspondence which is the place the cell constantly trades concoction messages between one another so they are in sink with each other. Thoroughly analyze the methods of intercellular correspondence utilized by the endocrine and sensory systems and examine the practical hugeness of the contrasts between the two frameworks. The sensory system performs present moment â€Å"crisis management† and the endocrine framework directs long haul, progressing metabolic procedures. The endocrine framework utilizes endocrine correspondence which directs hormones through the circulatory framework and the sensory system portion not have the capacity to do this. Another critical distinction is synaptic correspondence, the sensory system utilizes this type of correspondence of neurons to discharge synapse at a neural connection exceptionally near an objective cell that bears the privilege receptors. This type of correspondence permits the body to respond rapidly to circumstances to escape from hurt. Clarify the general instruments of hormonal activity and distinguish which hormone types work through every components. A hormone receptor is a protein particle to which a specific atom ties emphatically. Every cell has receptors for reacting to a few unique hormones, in any case, cells in various tissues have various mixes of receptors. For each cell, the nearness or nonappearance of a particular receptor decides the cells hormonal sensitivities. Hormone receptors are found either on the cell layer or inside the cell. The components of hormonal activity are that receptors for catecholamines, peptide hormones and eicosanoids are in the cell layer of target cells. Thyroid and steroid hormones cross the cell layer and tie to receptors in the cytoplasm or core, enacting or inactivating explicit qualities. Portray the control of endocrine organs. The endocrine organs are constrained by three components of the hypothalamic control. One is the discharge of administrative hormones to control action of front flap of pituitary organ. Two the creation of ADH and oxytocin. Lastly is the control of thoughtful yield to adrenal medullae. Clarify the basic and utilitarian connection between the pituitary organ and the nerve center. The pituitary organ discharges nine significant peptide hormones that all predicament to the layer receptors and utilize cyclic-AMP as a subsequent detachment. The pituitary organ balances second rate compared to the nerve center which all the front flap of the pituitary organ to help in the capacity of the hypophyseal gateway framework. By the nerve center discharging explicit administrative hormones it controls the creation of hormones in the foremost flap. This entire framework attempts to mystery hormones from the nerve center through the pituitary organ in a system of vessels that are associated. This guarantees all the hypothalamic hormones entering the entrance vessels will arrive at the objective cells in the front flap of the pituitary organ before entering general flow. Anticipate how variations in hormone creation, conveyance, or gathering by target tissues would influence its activity and blood focus levels. Depict the elements that could decide a cells hormonal affectability. Cells affectability is controlled by two factors down-guideline and up-guideline. Down guideline is a procedure wherein the nearness of a hormone triggers an abatement in the number of hormone receptors. This procedure is when levels of specific hormones are high, cells become less delicate to it. Up-guideline is a procedure wherein the nonattendance of a hormone triggers an expansion in the quantity of hormone receptors. In this procedure the levels of a specific hormone are low, cells become increasingly delicate to it. Distinguish the hormones delivered by the front and back flaps of the pituitary organ and indicate the elements of those hormones. The foremost projection produces seven hormones: Thyroid-animating hormone (TSH) focuses on the thyroid organ and triggers the arrival of thyroid hormones. As dissemination groupings of thyroid hormones rise, the pace of TRH and TSH creation decrease. Adrenocorticotropic hormone (ACTH) animates the arrival of steroid hormones by the adrenal cortex and targets cells that produce glucocorticoids. Gonadotropins direct the exercises of the gonads. Follicle-animating hormone (FSH) advances follicle improvement in females and, in blend with luteinizing hormone, animates the emission if estrogen by ovarian cells. In guys, FSH animates sustentacular cells, particular cells in the tubules where sperm separate. Luteinizing hormone (LH) prompts ovulation, the creation of conceptive cell in females. Likewise advances the emission, by the ovaries, of estrogen and the progestin, which set up the body for pregnancy. In male hormone is once in a while called interstitial cell- invigorating hormone (ICSH), since it animates the creation of sex hormones by the interstitial cells of the testicles. Prolactin (PRL) works with different hormones to invigorate mammary organ improvement. Development hormone (GH) invigorates cell development and replication by quickening the pace of protein combination. The back flap produces two hormones: Antidiuretic hormone (ADH) is discharged in light of an assortment of boosts, most remarkably an ascent in the solute focus in the blood or a fall in blood volume or pulse. An ascent in the solute focus invigorates specific hypothalamic neurons. Oxytocin (OT) invigorates smooth muscles withdrawal in the mass of the uterus, advancing work and conveyance. After conveyance this hormones invigorates the withdrawal of myoepithelial cells around the secretory alveoli and the pipes of the mammary organ, advancing the discharge of milk. Conversation the aftereffects of strange degrees of pituitary hormones Strange degrees of pituitary hormones can have a cast and complex effect on the development, fruitfulness, and capacity on the human body by means of the impact of the hormones on their target organs. Illnesses anyplace from asthma to development issues can happen. Distinguish the hormones delivered by the thyroid organ, determine the elements of those hormones, and talk about the causes and consequences of strange degrees of thyroid hormones. The thyroid organ produces thyroglobulin, tyrosine, and thyroxine. The elements of these hormones are: Thyroid hormones enter target cells by methods for a vitality subordinate vehicle framework and they influence pretty much every cell in the body. Thyroid hormones bound to cytoplasmic receptors are held away until intracellular degrees of thyroid hormone decrease. Thyroid hormones bound to mitochondria increment ATP creation. Thyroid hormones bound to receptors in the core actuates qualities that control vitality usage. The calorigenic impact: the cell expends more vitality bringing about expanded warmth age. In developing youngsters, thyroid hormones are fundamental to ordinary advancement of the skeletal, solid, and sensory systems. The thyroid organ is principally answerable for a solid, quick, and brief increment in the pace of cell digestion. The central point controlling the pace of thyroid hormone discharge is the convergence of TSH in the circling blood. The reasons for unusual degrees of thyroid hormones can make an iodide inadequacy since in the U.S. we expend more than they every day sum required. Thyroid hormone creation decreases, paying little mind to the flowing degrees of TSH. Portray the elements of the parathyroid hormones, and the impacts of irregular elements of every hormone. Parathyroid hormone has four significant impacts: 1. It invigorates osteoclasts, quickening mineral turnover and the arrival of Ca2+ from bone. 2. It hinders osteoblasts, decreasing the pace of calcium affidavit in bone. 3. It upgrades the reabsorption of Ca2+ at the kidneys, lessening urinary misfortunes. 4. It animates the arrangement and discharge of calcitriol at the kidneys. The impacts of calcitriol supplement or upgrade those of PTH, however one significant impact of calcitriol is the upgrade of Ca2+ and PO43-retention by the stomach related tract. The parathyroid organs, supported by calcitriol, are the essential controllers of blood calcium I levels in solid grown-ups. At the point when the parathyroid calcium levels become strange there are two issue that can happen. Hypoparathyroidism the organ secretes low calcium fixations in body liquid. Hyperparathyroidism is when calcium fixations become unusually high. Distinguish the hormones created by the adrenal cortex and medulla and indicate the elements of every hormone The adrenal cortex privileged insights the hormones adrenocortical, mineralocorticoids, glucocorticoids and androgens. The adrenocortical steroids or corticosteroids are fundamental: if the adrenal organs are decimated or expelled, the individual will kick the bucket except if corticosteroids are managed. Mineralocorticoids increment renal reabsorption of Na+ and water which quickens urinary loss of potassium. Glucocorticoids discharge amino acids from skeletal muscles and lipids from fat tissue; advance liver arrangement of glucose and glycogen; advances fringe usage of lipids; against inflamma

Rebuild your career after job loss

Modify your vocation after occupation misfortune In the event that you’re understanding this, it might be on the grounds that the most exceedingly terrible has just occurred: you’ve been laid off or terminated. Or on the other hand maybe you’re preparing for the doomsday situation, to be safe. In any case, realize that a cutback or a terminating isn't a real existence finishing (or even profession finishing) thing. At the point when it occurs, the stun and obliteration can prompt negativity about your subsequent stages. However, attempt to remember these tips on the off chance that it transpires. Realize that it’s alright to grieve.Job misfortune is a colossal change. Schedule, soundness, future arranging these are likely overturned by the news. It’s alright to let yourself feel the scope of feeling after it occurs, similar to outrage, melancholy, dread, and embarrassment. You may attempt to act courageously, yet don’t attempt to subdue the feelings by and large. Acknowledgment and proceedi ng onward mean working through the sentiments as opposed to disregarding them.Take it as an opportunity.No, truly. It most likely doesn’t feel like one-I know when I got laid off, I felt cynicism sneaking in immediately. Yet, soon I began to understand that I’d despised my activity, and this was an opportunity to begin once again without settling on the intense choice to stop and leave. This activity misfortune takes away your very own portion office (we as a whole need things to be on our own terms), however once it occurs, hold onto it as an opportunity to begin once again. Perhaps it’s time for a profession change?Don’t lie about it.You’re going to need to proceed onward to a new position, and that implies figuring out how to turn what occurred at your last one. It very well may be enticing to lie about the conditions under which you kept separate from a feeling of individual pride or dread of dismissal, yet don’t do it. In the event that you were terminated for an explanation, that will probably come up during either reference checks or historical verifications (on the off chance that it was serious).On your resume, you don’t should be explicit about what occurred. In any case, you ought to be set up to examine it in a meeting. â€Å"Why did you leave your last job?† is a typical default inquiry question, and it’s essentially inescapable that you’ll face it sooner or later. On the off chance that you were laid off, a reaction like â€Å"my position was eliminated† or â€Å"the organization downsized† is absolutely adequate. In the event that you were terminated, you can give a general clarification concerning why, and clarify a) what you gained from it; and b) how that information makes you a superior worker. Fresh opportunities are certainly feasible, yet you need to put forth a decent defense for yourself.Whatever the conditions, recall that you’re still alive, you ’re still you. The positive characteristics you bring to the table are at last more significant than your past, so as long as you set aside the effort to gain from the experience and ponder how to repackage yourself, you can transform it into a lifelong chance (if an excruciating one).

Letting Go of Sentimental Items

Letting Go of Sentimental Items My mother died in 2009. She lived a thousand miles away, and it was my responsibility to vacate her apartment in Florida. It was a small, one-bedroom place, but it was packed wall-to-wall with her belongings. Mom had great taste (she could have been an interior designer), and none of her stuff was junk. Nevertheless, there was a lot of stuff in her home. Mom was constantly shopping, always accumulating more stuff: She had antique furniture throughout her apartment, a stunning oak canopy bed that consumed almost her entire bedroom, two closets jam-packed with clothes, picture frames standing on every flat surface, original artwork adorning the walls, and tasteful decorations in every nook, cranny, and crevasse. There was 64 years of accumulation in that tiny apartment. So I did what any son would do: I rented a large truck from U-Haul. Then I called a storage place back in Ohio to make sure they had a storage unit that was big enough. The truck was $1600, the storage facility was $120â€"financially I could afford it, but I quickly discovered  the emotional cost was much higher. Initially,  I didn’t want to let go of anything. If you’ve ever lost a parent, a loved one, or been through a similarly emotional time, then you understand exactly how hard it was for me to let go of any of those possessions. So instead of letting go, I wanted to cram every trinket, figurine, and piece of oversized furniture into that storage locker in Ohio, floor to ceiling. That way I knew that Mom’s stuff was there if I ever wanted it, if I ever needed access to it for some incomprehensible reason. I even planned to put a few pieces of Mom’s furniture in my home as subtle reminders of her. I started boxing up her belongings: every picture frame, every porcelain doll, and every white doily on every shelf. I packed every bit of her that remained. Or so I thought. I looked under her bed. Among the organized chaos that comprised the crawlspace beneath her bed, there were four boxes, each labeled with a number. Each numbered box was sealed with packing tape. I cut through the tape, and when I folded back the boxes’ flaps I discovered old papers from my elementary school days from nearly a quarter-century ago: spelling tests, cursive writing lessons, artworkâ€"it was all there, every shred of paper from my first four years of school. She obviously  hadn’t accessed the sealed boxes in years, yet Mom had held on to these things because she was trying to hold on to pieces of me, pieces of the pastâ€"much like I was attempting to hold on to pieces of her and her past. I realized my retention efforts were futile: I could hold on to her memories without her stuff, just as she had always remembered me, my childhood, and all our memories without ever accessing those sealed boxes under her bed. She didn’t need papers from 25 years ago to remember me, just as I didn’t need a storage locker filled with her stuff to remember her. I called U-Haul and canceled the truck. And then, over the next twelve days, I donated her stuff to places and people who could use it. Of course it was difficult to let go, but I realized many things about our relationship between memories and possessions during the experience: I am not my stuff; we are more than our possessions. Our memories are within us, not within our things. Holding on to stuff imprisons us; letting go is freeing. You can take pictures of items you want to remember. Old photographs can be scanned. An item that is sentimental for us can be useful for someone else. I don’t think sentimental items are bad, or evil, or that holding on to them is wrong; I think the danger of sentimental items (and sentimentality in general) is far more subtle. If you want to get rid of an item, but the only reason you are holding on to it is for sentimental reasonsâ€"and if it is weighing on youâ€"then perhaps it’s time to get rid of it, perhaps it’s time to free yourself of the weight. That doesn’t mean you must get rid of everything, though. When I returned to Ohio, I had four boxes of Mom’s photographs in my trunk, which I would later scan and save online. I found a scanner that made scanning the photos easy. Those photos are digital now, and they can be used in digital picture frames instead of collecting dust in a basement. I no longer have the clutter of their boxes lying around and weighing me down, and they can never be destroyed in a fire. I donated everything else strewn throughout her home: her furniture, her clothes, and her decorative items. It was a giant leap for me, but I felt I must do it  to remove the weightâ€"the emotional gravitasâ€"of the situation from my shoulders. I don’t need Mom’s stuff to remind me of herâ€"there are traces of her everywhere: in the way I act, in the way I treat others, even in the way I smile. She’s still there, and she was never part of her stuff. Whenever I give advice on paring down, I tend to offer  two options: The first option is usually the Giant Leap option, the dive-in-head-first option: get rid of everything, smash your TV, throw out all your stuff, quickly rip off the Band-Aid, let it go! This option isn’t for everyone (and it’s often not for me), but in the case of my mom’s stuff, this is exactly what I did. The second option is to take Baby Steps, which works because it helps you build momentum by taking small, incremental actions. What sentimental item can you get rid of today that you’ve wanted to get rid of for a while? Start there. Then pick a few things each day, gradually increasing your efforts as you feel more comfortable. Whichever option you choose, take action: never leave the scene of a good idea without taking action.

The Effect Of Insulin Humalog On Lowering Blood Glucose...

Audience and Purpose of Description The audience for this description is the population of Type I Diabetes, Type II diabetes, their caregivers, they health care providers, as well as general public interested in this process. The purpose of this technical document is to inform the audience, step by step how Insulin Humalog works in lowering blood glucose level. Introduction to Process Every human body wants to maintain blood glucose (blood sugar) level in normal range (70-100mg/dl). After we eat, the stomach digest food breaking it down into type of sugar, called glucose. Furthermore, this glucose is released into the bloodstream (Figure 1). The rise of glucose level triggers the pancreas, one of the body’s organ, to release insulin, a hormone, it blood stream.

ABSTRACT: Purpose – The main objective of this review is to assess thoroughly the Sino-African relations across time and now the newly introduced â€Å"One Belt One Road† (OBOR) initiative especially the contribution to academic literature. The focus is on the major events that marked the story of Africa since China developed an interest until the new OBOR initiative and the conclusion highlights the importance on the study by comparing and contrasting the different perspectives in previous literature. Approach – We considered an integrated and comprehensive literature based on a qualitative approach, we performed a content analysis of highly relevant and impactful papers. We will write a custom essay sample on Sino-African win-win Policy under the One Belt One Road or any similar topic only for you Order Now Findings – In this paper, we analyze usually controversial issues and express our viewpoints to conclude. However, the controversies remain a hot topic for further research works to be handled with different methodologies and new theoretical approach. Implicit assumptions may always exist in terms of a quantitative assessment of the benefits from the China-Africa relations. Major differences in narratives exist between Western and Southern stakeholders. Limitations and Implications – The conclusions from the work could be supported by additional research by considering a wider scope of the analysis. To give more clarifications to the empirical findings, more works needed to be done using quantitative data and qualitative evidence that extend beyond the usual economic and geographical limits as well as the socio-political limits. Value – This paper reviews decades of research on China in Africa and presents a snapshot of the recent OBOR initiative. It further draws attention to the necessity for subsequent literature to explore new methods of analysis for better understanding of the China-Africa relations and the role each part plays to the sustainability of this cooperation. Keywords: Africa, China, relationship, One Belt One Road. How to cite Sino-African win-win Policy under the One Belt One Road, Papers

Problem Solving Activities for Cyber Computing - myassignmenthelp

Question: Discuss about theProblem Solving Activities for Cyber Computing. Answer: This report reflects the case study analysis and how Sarah could minimize the risk of losing money in her business. This case has shown the problem of management of inflow and outflow of cash and fear of losing money due to non-effective recording of cash inflow and outflow. However, in order to mitigate these problems, Sarah could use cyber computing enterprises resources planning in its business. This will increase the transparency of business reporting frameworks. Identification of problems Sarah has problem in recording of right amount of cash inflow and outflow of business. She has also observed that despite of no decline of sales, cash inflow in business has gone due by very drastic amount. The business of Sarah is accompanied by the various internal and external recording of cash in business. This is very basic problem which each and every business faces. However, in order to mitigate these issues, Sarah needs to change business staff or should make proper surveillance on its cash recording transactions. Ideally, hiring accountant or matching cash book with the financial statement of company could show case all the discrepancies in recording of business financial transactions. In addition to this, double entry system will mitigate possible problem of management of business transactions in determined approach (He, Zha Li, (2013). Analysis the problem The main problem which Sarah has faced in its business is related to recording of cash of in its business. However, after analyzing the case, it is observed that decline in the overall cash inflow may be arise due to the change in the operational activities or increased investment in particular activities of business. Company could use cyber computing enterprises resources planning in its business or accountant to match its all the dr. and cr amount. This double entry system will increase the overall efficiency of business and increased value of business at large. This recording of cash transactions has occurred due to the non-effective recording system. If company could mitigate these recording of cash transactions then these fear of losing cash may be overcome. However, Sarah needs to install proper mechanism and should follow IFRS transactions recording format. This will increase the effectiveness of recording business transaction in determined approach (Hancock Algozzine, (2016) . Formulate possible solution After evaluating the possible problems and factors of organization, it is considered that Sarah needs to identify the actual problem of decline of cash and trustworthiness of their employees. If Sarah finds that new students hired as trainee in the organization could be culprit then he should hire some other person in management of cash inflow and outflow. In addition to this, adoption of cyber computing enterprises resources planning in its business accounting system will increase the transparency and valuation of assets in determined approach. After evaluating all the data, it is observed that if Sarah could install cyber computing enterprises resources planning in its business then it will increase the transparency of all the business transactions and loss of money in its business. However, in the initial time, it will increase the overall cost of capital of business but eventually it will keep Sarah away from the fear of losing money. The main target of Sarah is to curb the recor ding of business financial transactions. Sarah needs to do the following activities (Grant, (2016). She needs to hire accountant who could asses all the internal and external flow of money and business goods. Installing cyber computing enterprises resources planning in its business will increase the transparency of business in recording of transactions Best possible solution which Sarah Roberts could undertake It is evaluated that all of the above given options are best for Sarah to curb the loss of its money in her business events. However, the best possible solution for Sarah is to install cyber computing enterprises resources planning in its business. This will not only increase the transparency of recording of transactions but also create fear in all the employees if they take wrong steps in business. This cyber computing enterprises resources planning in its business will make the payment mode online and currency value transactions will be dematerialized and loss of money fear will be eliminated directly. Now in the end, it could be inferred that losing of money in business is the basic fear which each and every businessman has to face. The best possible action is to adopt the cyber computing enterprises resources planning to establish automation in business. References Grant, R. M. (2016).Contemporary Strategy Analysis Text Only.

The Myth Of Sysiphus Essays - Albert Camus, Sisyphus,

The Myth Of Sysiphus Albert Camus wrote the Myth of Sysiphus. The stories main character is Sysiphus. He lived in Ancient Greece and was the founder and king of a prosperous city called Corinth. Sysiphus was an extremely smart and clever man but did indeed possess a passionate desire to outwit the gods. Sysiphus also possessed a highly rebellious nature. During his time, he was a mortal man who had the audasity to match wits with the gods. Sysiphus was condemned to role a rock up to the top of a mountain, watch it role back down again, and then push it back up again. His passionate and rebellious nature combined with his desire to outwit the gods is what led to his fate of futile labor. For example, Jupiter, the god of the Sea, abducted Aegina, the daughter of Aesopus. Aesopus was naturally quite distressed by this event and went to Sysiphus to complain of this monstrosity. Sysiphus knew where Aegina had been taken. He then told Aesopus where Jupiter had taken Aegina on the Condition that that Aesopus would provide water to the city of Corinth. Sysiphus tricked death when it came and took him to the underworld he left death there in chains. Sysiphus also once wanted to test his wife's love for him. He ordered her to publicly display his body and not give him a proper burial. Once he was condemned to the underworld he complained to Pluto that he needed to return so that he could chastise his wife. After once again seeing the pleasures of this world he didnt want to return to the underworld and for many years he did not. Once again the gods had bee n outwitted by Sysiphus, a mere mortal. This angered them deeply. Mercury came to seize Sysiphus and ,at once, condemned him to the underworld to carry out his Fate. Albert Camus, the author of the Myth of the cave wrote this Myth during the tumultuous Shambles of WWII. All around him he witnessed the pain and suffering people had to indure from the outcome of war. He had a bleak but courageous outlook for what one could only imagine to be a very trying time for people. Camus believed that the essence of man was irrational and life is nonessential, but one should face life with a sort of courageous humanism. Camus rather enjoyed the more rebellious side of human nature. Camus is most interested in Sysiphus because when faced with this futile punishment he chooses a rather unusual manner to deal with it. In his writing Camus focuses most on the moment of time when Sysiphus is coming down the mountain. He describes Sysiphus as being in a conscious and lucid state. He feels tragedy, victory, and a bit of sadness for his situation. It is during this time of consciousness that Sysiphus begins to formulate drastic conclusions about his fate. During his descent, he decides that he and only he can control his own destiny. He faces the reality of his situation and makes a conscious decision to reject any god that would have him endure futile suffering. He decides that his fate will lie within his own hands and therefore he and only he will decide whether or not he will allow this condemnation to render him powerless or powerful. In this moment of adversity he finds the courage within himself to continue on and decide for himself that god will not make him suffer. Sysiphus decides that he will be happy. He will be superior to his fate. Once he rejects god he sees that because of his own nature he can create his happiness. Camus is most interested in this side of Sysiphus. He wonders how one can grasp the consciousness to be happy in the face of such adversity given this terrible punishment. Camus realizes that Sysiphus' joy is contained within. His fate belongs to him. Camus states that one cannot know what it means to be happy unless one has known what it means to experience sorrow. Sysiphus has, even to the end, managed to outsmart the gods. The gods gave him what they considered a punishment that would surely make any

Nafta and Mercosur essays

Nafta and Mercosur essays While still in office, President Bill Clinton emerged from a meeting with 33 Western Hemisphere leaders and made an ambitious pledge. By 2005, he promised, a ''Free Trade Area of the Americas would stretch from Alaska to Argentina'' and ''will be the world's largest market.'' He had the idea of combining all trading blocks and emerging as one huge western connection. The question now remains, should the new President strive to accomplish the goal of Clinton? Would the combination of the North American Free Trade Agreement (NAFTA) and the South American Common Market (MERCOSUR) be a good idea, or even possible? Would it be in our best interests to link ourselves in contract with not only Canada and Mexico but Brazil, Argentina, Paraguay and Uruguay as well? The answer is definitely yes. As it is now, NAFTA is starting to fail in many peoples eyes. Though it has brought success to some, it has caused distress for most. The inclusion of the South American countries and the MERCOSUR ways could only make the United States more successful economically. To understand why things need to change in order to better our economy we must first know the background information. On January 1st, 1994, the North American Free Trade Agreement went into effect, creating the worlds largest free trade area. Among the main objectives is the liberalization of trade between Canada, Mexico and the United States, to stimulate economic growth and give the NAFTA countries equal access to each others markets. Some of the promised benefits were 200,000 new U.S. jobs from NAFTA per year, higher wages in Mexico, a growing U.S. trade surplus with Mexico, environmental clean-up and improved health along the border. The most important feature of NAFTA that would benefit the people is employment and the promise that NAFTA would create hundreds of thousands of new, high paying jobs. There was also a promise that wages in Mexico would increase due t...

The main aim of this project is to find the proper liquid level sensors between these two sensors for working in Riyadh wastewater treatment station. By the end of the project, one of the main reason which causes a problem to the ultrasonic level sensors at Riyadh station came up which is a high temperature or temperatures Variety. According to Monitoring weather center in Riyadh, the average temperature at the summer time between 40-55 degree in the day time and the moisture in Riyadh is very low. Therefore the ultrasonic sensor might get affected by the Variety of temperatures or high temperature. As result of low moisture and high temperatures, I think the proper sensor for Riyadh wastewater station is the optical infrared sensors. In part of characteristics consideration for both sensors to select the suitable one for wastewater environment, the accuracy of the optical sensor for detecting the distance between the sensor and the liquid level is noticed even though the variations of surrounding temperature and sunlight intensity. The sensor was affected by dirt and misroute. The ultrasonic sensor is able to detect the distance even though the variations in moisture content, dirt and surrounding sunlight intensity. And, the sensor was severely affected by the difference of the surrounding temperature. Finally, both sensors can be used as distance detection sensor in the wastewater treatment field,† if a careful consideration is given to the characteristics of both sensors with improvement on problems pointed out in this study†.

Recession in the economy Essay Example | Topics and Well Written Essays - 500 words

Recession in the economy - Essay Example Hence, countries are expected to come up with various macro and microeconomic policies that spur positive growth so that their economies can recover from the menace. Such is the case in Poland if they want to redeem the situation. Consumption forms a critical development criterion in any economy and the state must find measures to spur the vice. The government should first reduce taxes on the basic goods and services as it would reduce the prices of the commodities. Consumers will increase the number of consumption bundles and have an extra income that they can spend on other goods. As a result, the consumption patterns increases that bring more money to manufacturers that they can invest and spur growth in the country. Another measure is by the Poland government to provide subsidies to the producers. The manufacturer's cost of operations will be reduced hence making cheaper commodities (Auerbach, Alan and Yuriy, pg 15). This policy will translate into low prices of goods and service s in the market that will reduce inflation. High consumption results in more sales that lead to high revenues. The firms can hence invest the excess income making them expand and, as a result, hire more workers that reduce unemployment in the economy. Through the central bank of the country, the benchmark lending interest for loans should be reduced to commercial banks. The reduced mortgage rates would be passed to consumers and investments in the form of reduced lending by the commercial bank. More persons and firms would acquire the loan services that they invest in major parts of the country. The policy is necessary because the interest rate is inversely related to investments levels. The higher the interest rate, the lower the investment and the opposite are right (Auerbach, Alan and Yuriy, pg 18). Therefore, due to low rates, investors will expand their production that increases the level of output within the economy. The increased production makes the gross domestic products t o raise that makes the country have a favorable trade balance with her business partners increasing economic growth in the country.

Looking At Wireless Power Transmission Information Technology Essay

Looking At Wireless Power Transmission Information Technology Essay Wireless power transmission is the process of transmitting electrical energy to an electrical load, from a source emitting power without interconnecting wires. The wireless transfer of electromagnetic energy as in different forms like audio format, video format and data format is common nowadays but wireless power transfer technology is still years ahead. Even though the idea was developed 100s of years ago and scientists are still working on the topic an efficient way for wireless transfer of power is yet to be developed. The development of highly efficient WPT technology will be a breakthrough in the history of wireless transmission as it allows lots of portable devices to be charged without plugging on to a socket or docked to a charging station. The development of WPT serves to be useful in many ways, as transmission of power in hazardous environment is inefficient and dangerous. The WPT differs from the wireless transmission of telecommunication signals as the WPT takes into consideration the efficiency parameter where as in the latter the energy parameter is significant only if the signal is distorted in such away that it cannot be distinguished. The WPT is economical if and only if the receiver receives the same amount of energy transmitted by the source. The direct induction method is the most common method used for the WPT and is being used for short distance WPT, but it had disadvantages and was overcome by later technologies developed like the resonant magnetic induction method, electromagnetic radiation methods like microwaves and lasers. The modern era where the ideology of high efficiency in practical circuits comes to existence, the WPT technology proves wrong due to the low efficiency of the developed technologies. The WPT technology in industries by electromagnetic radiation is possibly only remote in the design and most of the industries are looking forward for better designs for better efficiency in power transfer. Most of such design lags the property of safe human environment for living and the economical barriers. A design of WPT system which overcomes these factors is still to be worked out and is being experimented throughout the world. Why Wireless Power Transmission (WPT)? The studies throughout the world has proven that most of the electrical energy transfer is done through the interconnection wires and lots of energy is lost during the transmission due to various internal and external factors like the resistance of the wires the material of the conduction wires, the size of the wires, the atmospheric conditions like temperature, humidity etc. On an average basis the loss of power due to transmission through wires is calculated to exceed to be more than 30%. This is where the WPT comes into action , the WPT is highly reliable, fast , low cost for the maintenance and can also be used for short range and long range distance transmissions. These factors pop-in the idea for WPT. History of WPT The WPT history can be traced from the early 19th century. The first electromagnet was developed in the year 1825 by William Sturgeon which paved the way for the discovery of principles of magnetic induction in the year 1831. This was followed by the demonstration of transmission and reception of electrical energy without wires to connect the point of origin and termination by Nicholas Joseph Callan using the above two developments. These experiments even though demonstrated was successful but in practical cases was always kept under suspicion which was due to the interpretance that it was not possible for long distance transmission and fear of safety. The invention of transmission of very and ultra high frequency radio waves dedicated to Heinrich Hertz followed the revolutionary development of the wireless electricity transfer by Nikola Tesla in the year 1891, on which he took the patent-ship for illuminating the bulbs wirelessly. Nikola Tesla is called as the pioneer of the induction techniques as his technique was based on induction method. His vision of WORLD WIRELESS SYSTEM which inculcated the idea of people accessing the free energy. He even planned to set working a 187 feet tall tower for broadcasting energy but was put down due to lack of funds. The experimentation in early 20th century was successful in transmitting power over a distance wirelessly but was not able solve the problem of power loss due to hindrances. In the 19th century WPT passed through various phases of technological developments. Even after 100 years the idea of Tesla is being used by the MIT scientists led by Soljacic for their project named WiTricity. Different technologies of WPT Near-field techniques: The techniques for short distance transmission of power wirelessly. Mostly the induction methods are used for near-fields. These techniques are as follows. (1)Inductive coupling Electromagnetic induction is a process whereby a conductor placed in a changing magnetic field results in the production of voltage across a conducting plate. This voltage in-turn generates an electrical current called the induced current because the current on the second conductor is induced by the first. In the inductive coupling technique the primary and the secondary are not connected by wires but the energy is transferred by mutual induction. Mutual induction refers to the generation of EMF in circuit due to a change of current in nearby circuit. Electromagnetic increases with the increase in current, the voltage in the conducting plate responsible for the magnetic fields and also the increase in the frequency. The energy is transmitted from the conducting plates which is responsible for the fields to another conductor termed the secondary where the fields impinge on. A part of the energy on the primary is passed inductively through space decreasing the energy in the primary and imparting energy into the secondary. High frequency currents are not liable to pass the current for long distances but transfers energy by induction rapidly to the adjacent or neighboring conductors. Lower the frequency of the current less preponderant becomes the effects of induction. The phenomenon is classified more local, if the energy decreases rapidly in the circuit causing the current in the circuit to die-out. In the space outside the conductor the phenomena results in dielectric stress and steady magnetic condition for continuous current and alternating for alternating current input. For the telecommunication channels the magnetic and electric fields outside conductor is only considered for the transmitting and receiving of messages. Transformer working is the simplest example for WPT. A current which is varying in the primary generates a varying magnetic flux in the core of the transformer which results in the varying magnetic field in the secondary. This field induces a varying voltage or EMF(electromotive force) in the secondary. This is termed as mutual induction. It should be noted that most of the energy transferring devices are usually air-cored. There are many examples of air-cored devices, such as the wireless charging pads, electric brushes etc. Induction coupling is the underlying principle of charging of an electric toothbrush. The input current through the primary winding creates a magnetic flux thus a magnetic field. When the toothbrush is placed in the charger, a current is induced in the secondary by the magnetic field, which is connected to the batter of the brush and thus recharges the battery. The wireless charging of the portable devices of great advantage as it is comfortable to use, shock proof and less usage of wires which is more economical. The figure() shows the picture of an wirelessly charged toothbrush. The principle to recharge several devices at a time is similar to that of the charging of electric brush. The Splashpower recharging mat and Edisions Electric PowerDesk are few examples. The WCP (wireless charging pads) are devices that are devised for the charging the battery automatically when placed on it. There is no connection with the wires between the charging pad and the device battery to be charged. The technique of induction to transfer energy is utilized in this and air acts as core. Resonance Inductive Coupling It is the combination of resonance principles along with the inductive coupling principles. When a relatively low frequency close to the same frequency of vibration as the natural frequency of system being resonated produces large amplitude of vibration it is called resonance. Two objects or bodies are made to strongly interact with each other during the time of resonance. It is also noted that an objects physical structure determines the natural frequency of vibration of the object. Objects vibrate more easily at resonant frequency than at other frequencies. We know that magnetic flux developed due to the passage of current in the primary creates a magnetic field which induces an EMF in the secondary and thus current was the principle of inductive coupling. Working principles of Resonance Inductive Coupling. The coil in the fig() provides the inductance when the circuit is supplied with voltage. The induction takes place in a slight different manner when the electromagnetic fields surrounding the coils start to resonate in the similar frequencies. The inductor used here is a curved coil wire. We also see a capacitance plate attached to each end of the coil to hold the charge, that is a capacitance, is connected in parallel to the coil on both sides that is the primary and the secondary coil. When electricity is passed through the coil the coil begins to resonate. The resonating frequency is the product of the capacitance of the plates and the inductance of the coil. Electricity which travels alongside the electromagnetic wave tunnels from the source coil to the target coil, if both of the resonant frequencies are the same, where resonance is a function of the product of the capacitance connected in parallel and the inductance of the coil. Loss of energy or power due to radiation is negligible in this case. If the two coils to be linked are out of range of one another, there occurs no transmission of power as the fields are not strong enough to affect the surroundings. This is the same affect when two coils which are resonating at different frequencies exists. Considering two coils resonating at the same frequency to be in the same range, energy streams moves from the transmitting to the recipetant. This theory also provides the functionality of more than one receiving coil in the same range operating at the same resonant frequency to function. This type of energy is termed as NON-RADIATIVE ENERGY TRANSFER as it involves the static fields surrounding the coils more than the fields spreading in all directions. Advantages of Resonance Inductive Coupling (RIC) over Inductive Coupling Compared to inductive coupling the efficiency of RIC is very high. The range of RIC is much greater than compared to the inductive coupling, range for inductive coupling is below 5 cm whereas for the RIC it in the range of few meters. The directivity of the RIC is larger compared to the inductive coupling. RIC can implemented in one-to-many format, but the implementation of inductive coupling is generally one-on-one format. The devices implemented using RIC are easily portable compared to that of the inductive coupling gadgets. This is because of the small size of the component structure and the ease to use. Air Ionization Ionization of air refers to the process of imparting charges that is negative or positive charge to the air molecules by the application of high voltage. In this method of transferring the electricity, the charged particles that are the anions or cations move from the source to the target terminal through the atmosphere, by imparting charges to the air molecules. This technique even though seems to be simple in construction, it is the most toughest and un-economical method of transfer of power in the near field techniques. The disadvantages are really more in this technique because minimum field strength of 2.11 Megavolt is required to transfer the electricity over a distance of 1 meter, which is very high potential difference to be created. There should be a static atmospheric condition for this technique to be implemented and mostly the dust particles in the atmosphere can also affect the transfer of electric power, from one terminal to the other terminal. The natural example is the lightening which occurs. So taking into consideration all the negative points which overcome the advantages, it can be concluded that Air ionization method for wireless energy transfer is not feasible for implementation. Advantages of near-field techniques The absence of wires is being considered as the greatest advantage. There is no presence of e-waste. The need for battery is suppressed to a certain extent. Efficient energy transfer using the RIC up-to a distance of few meters is possible. The methods are harmless, if the strength of the fields used are under safety levels prescribed by the standards prescribed. The maintenance cost is considerably low for the devices in the near field techniques. Disadvantages of near-field techniques One of the main disadvantages of the near-field techniques is the distance. This technique implies the wireless transfer of energy only for a short distance. It has to be taken care of that, the strength of the fields developed should be below the safety level so that it does not affect the human safety. The initial capital for setting the circuit is considerably high. The tuning of the RIC circuit is a difficult task and consumes more time. The signals to the supply should be having high frequency because the induction is proportional to the frequency of the signal supply. The air ionization process for the near-field technique is not a feasible technique that can be implemented for the wireless transmission of energy. Far-field techniques for wireless power transmission Far-field techniques for WPT refer to transfer of power from one terminal to another terminal which is kept far apart. The techniques used for near-field transfer are not viable because the efficiency will be tending to zero or almost zero if implemented by those techniques. That is the power received at the receiving terminal will be zero. There are mainly two types of techniques used for the energy transfer in far-field techniques they are as follows Microwave wireless power transfer The electromagnetic waves that are arranged in between the infrared spectrum and the radio wave spectrum are termed as microwave. Their frequency ranges in from 300 Mega hertz to 300 Giga hertz. They are used for a wide range of applications such as Bluetooth, wifi, microwave Owen etc. The frequency range of microwave is in between 1 and 40 GHz which is generally used for applications. For long distance transfer of power, microwave is one of the best medium used. The microwave band is generally used because antennas of convenient sizes that are able to transmit and receive the microwave signals and also the metal waveguides for carrying the radio power works are available. Besides this the technologies in electronics where millimeter waveband is required the microwave proves to be helpful. This is because in millimeter wavelengths the radio waves are attenuated while the microwaves are not. The microwave was used for transmission of power for various applications such as running of the unmanned helicopter developed by Americans, powering the outer space vehicles etc. There are mainly three steps involved in the transmission and reception of power by MPT. Step1: The conversion of electrical energy into microwave. After this process the microwave is emitted with very-high power emitters called the cavity magnetrons. Step2: The microwave is then captured using a rectenna. The rectenna is a combinational circuit consisting of rectifier and an antenna. Step3: Microwave energy is converted to electrical by the rectenna. In the process of transmitting microwave, the AC supply needs to be converted to DC as it is not possible to convert the AC directly to microwave. The process of conversion of DC to microwave is done by magnetron. The magnetron is a highly powered vacuum tube structure that is responsible for the production of coherent microwaves. The rectenna can also be called as rectifying antennae as it converts the microwave directly into DC electricity. Rectenna consists of elements that are sorted in multi element array and consists of pattern reflector element mesh to give directionality. It is easily constructed by placing Schottky diode in between the antennae dipoles. The DC is converted back in the next process using an inverter circuit. Considering the receiver to be a photovoltaic cell, the microwave system for earthbound applications exceeding an area limit of diameter size 10 Km the arrays in the receiving station has large power levels in total , limiting the exposure of electromagne tic radiations which is considered for human safety. A density of power equals to or less than 1mW/cm2 is considered safe for human environment, and with this density of power for a diameter of 10 km 750 megawatts of power can be generated. This standard value is utilized by several modern power plants in the world. Laser transmission of power A device emitting electromagnetic radiation by the process of optical amplification on the basis of stimulated emission is termed as laser. Laser has high directivity and high degree of temporal and spatial coherence which is a unique property of laser that cannot be attained by any other technologies. The laser beams does not get dispersed for long during the time of transmission. The disadvantage of the laser is that it gets attenuated while propagating through the atmosphere because of hindrance due to the dust particles prevailing in the atmosphere. The receiver designed for the laser power transmitter and receiver is simple in design and construction. The laser system is a cost efficient system due to the simple design and structure. These points form positive side for the implementation of the laser system. The receiver in the case of laser system is a photovoltaic cell. The laser system is mainly used when electromagnetic radiation in the spectrum near to visible region that is 10s of nm or microns are to be transmitted, power is transmitted changing electricity in the form of laser beams and then projected onto a photo-voltaic cell which acts as the receiver. The receiver then turns it back to electricity. This is called the power beaming mechanism. This is so called because power is forced or beamed at the receiving end to convert the power into useful electric energy. The fig() shows the concept how laser is used for transferring the power to an object in the sky. Here it represents flying objects battery being charged by controlled transmission of laser beams, tracking the object with the help of the radar, and powering the target with the help of laser generating source. Comparison of Laser and Microwave techniques Laser method requires antennae of smaller sizes compared to that of the microwave technique of power transfer. Microwaves interferes with each other where as laser is highly monochromatic and does not interfere (two frequencies used for microwave power transfer are 2.45GHz and 5.4 GHz). Laser gets attenuated and also diffracted due to the particles present in the atmosphere, but microwave is resistant to this. Transmission of energy over a long range is possible due to property of collimated monochromatic propagation of wave-front in lasers but the range of microwave is small considered to lasers. The receiver size of the laser technique is small considered to the microwave method because of the compact size of the photovoltaic components. The laser beams does not affect or interfere the normal radio communication due to the large difference in their wavelengths, but microwave as it has wavelengths closer to that of the radio communication channel wavelength the possibility of interference is more. The photovoltaic cells in the laser receiver is not as efficient as in the microwave receiver as in laser, only 40%-50% efficiency is only acquired. Advantages of far-field energy transfer Far-field energy transfer is more efficient. The need for setting substations, grids etc are eliminated due to the large distance transfer ability. These systems require less maintenance cost compared to the wired system of energy transfer. The systems become more and more effective if the transmitter and the receiver are along the line of sight. This system can be implemented in remote locations where access is difficult. Disadvantages of far-field energy transfer techniques This is radiative in nature so the losses are prevalent due to the radiations. In order to be more effective in working the transmitting and receiving stations must be in line of sight. When lasers are used: (1) conversion to electrical energy is inefficient at the receiver. (2)absorption loss is high due to the atmospheric particles which causes attenuation and diffraction in lasers(3) difficult to use in human environment. When microwaves are used (1) interference of two power signals (2) standards should considered for the sake of healthy living environment. Applications Near-field energy transfer Electric automobile charging The automobiles running on electricity are more common nowadays as it more environmental friendly, but the storage capacity of these vehicles are limited as it cannot afford huge batteries, so similar to the petroleum bunks, rises the concept of recharging stations. But these recharging stations cannot afford large number of plug-ins, as the density of vehicles increases besides it is a waste of time working with plug-ins in this busy and fast world, so wireless recharging of the vehicles is done in these situations to avoid waste of time and energy by near-field techniques, besides all these many vehicles can be recharged at a time using resonance inductive coupling. Consumer electronics In the world of consumer electronics, the technology changes are really fast. Each technology brings in more compacability and introduces more functionality into the products being manufactured. Such a world essentially requires the introduction of the wireless charging, because it reduces the cost of the wires plugged on to it, increases the reliability of use of the equipment, reduces the total size of the equipment and increases the ease of portability etc. Inductive coupling or resonance Inductive coupling techniques prove to be useful in these cases. Example is electronic toothbrush charger, splash power recharging mat etc. Industrial applications In industries there are processes involving high temperature, hazardous environment created by chemical reactions etc. In such an environment if wires are used for the transfer of electricity if required, it is highly inefficient and at times dangerous, so in such cases only the wireless transfer of electricity is possible, the methods of inductive coupling and resonance inductive coupling proves to be efficient because the hazardous environment or the high temperature does not affect the transfer of energy wirelessly. Far-field energy transfer Solar power satellites In this era of growing need of energy, our mother earth with all its resources may not be able to supply enough energy for the utilization for mankind, besides the energy earned from coal, oil etc are causing pollution besides this, these non renewable sources of energy. So in order to satisfy human needs one of the latest technologies for energy harvesting is the solar power satellites. These are machineries working on the basis of the microwave and laser power transmission methods. These helps to efficiently make use of the solar energy, and are placed in geostationary orbits for the efficient working. Solar energy is captured using the solar cells on the satellite; where in 400 million photocells are present in each solar power satellite. The energy is converted to microwaves or laser and transmitted to the earth and received at the earth station using the rectenna or photovoltaic cell converts it into electrical energy. The efficiency of the microwave system is more than 95% usually, but for the laser power transfer system the efficiency is around 40% to 50%. The diagram in the fig() shows the working of the solar power satellite and how it transfers power from the supply terminal to the receiver terminal by microwave method of power transfer. This is also called BEAMING DOWN process. Energy to remote areas In remote location that is places that cannot be accessed easily by people, the transfer of energy by using grids are considered to be waste of money, time and energy. In such cases the transfer of energy through wireless media is only possible. Certain factories which produce hazardous wastes, confidential or secret services offices and plants of nations etc are sometimes located in remote locations are the examples. There are villages to be supplied with electricity located in remote locations government of nations are planning and implementing far-field techniques of power transfer to meet these tasks. Energy broadcasting globally The concept of energy broadcasting globally had bought in nations to work together in projects dealing with more efficiently trapping of solar energy to power up their resources. As solar energy is renewable source and available in plenty the only step left behind is more efficient way of trapping the solar energy. The achievement of this would certainly result in reducing the crisis of energy, and to broadcast the energy globally. One of the famous projects undertaken is based on Kalams (former Indian president) vision which calls in the program for space-farming to contribute substantially for the global energy broadcasting. One such proposal is Pan African e- network. Projects established on the basis of wireless power transfer. Wi-Tricity This was a project done in Massachusetts Institute of Technology on wireless transfer of energy based on the resonance inductive coupling method. The team was led by Marin Soljacic. The team was able to transfer energy wirelessly for a distance of 2m. The coils used for the experiment was helical in shape and they never used any capacitor in the experiment. The energy received at the receiving terminal was almost 40% of the total input power from the supply. The frequencies used for the transmission of power were 1MHz and 10MHz. The field strengths were safer at 1 MHz frequency for the human environment. The usage of 10MHz frequency, created fields of strength above the ICNIRP (International Commission on Non-Ionizing Radiation Protection) standards. Rectenna in US The rectenna build in USA worked on the microwave method of wireless energy transfer. The rectenna which was spread over one and half mile in was diameter was able to generate electric power of 5000MW. The range of frequency of microwave used is compactable to the ICNIRP standards. Alaska 21 WPT can be used for supplying power to rural areas. Alaska 21 project was presented in the year 1993, for supplying power to villages in Alaska. The other sources of energy were not possible to be used because of the limited infrastructure. The price estimate of $40/kWh was done for energy produced by other sources, which is too high to accommodate. Even cabling to this area was not possible due to extremes of climatic conditions. So a pilot project was conducted which was passed on WPT, not only to supply energy but also to avoid pollution. The system consisted of 2.45 GHz design array and could bridge around 1 to 15 miles. Present status is unknown. Grand Basin project This project aims in supplying electricity to an isolated mountain village in the remote area of the La Reunion Island. This project was developed for making Grand Basin to a tourist village. The project was given complete support by CNES, which is the French space centre. WPT was used as the underlying basis of the project. Planning to build a microwave link which operates at 2.45GHz frequency working over a distance of 700 meters delivers 10kW and had an efficiency of 57%. The whole system worked in combination with the photovoltaic panels and the batteries. Capital of 1 million dollars for 10 kW was proposed and the project was put down. WPT Demonstration in Hawaii In the year 2008 on moth of May a demonstration based on WPT was held on the islands of Hawaii. The demonstration was organized by one of the US based companies named Managed Energy Technologies. They were able to demonstrate wireless power transfer up to a distance of 148 km. They were only able to transfer 20 watts of power, which would barely light a fluorescent lamp, because most of the energy were lost during the time of transmission. The limitation of this demonstration was not the science but the capital involved. This project involved less than a million dollar. If the company could have afforded more number of solar panels and more phased transmitter array and receivers more than 60% of efficiency could have been acquired. Munich electronica exploration The Munich ELECTRONICA exhibition organized by the automotive, embedded, electronica and the ZEVI forums in the month of November from 9th to 12th in Germany was a real trade off for the electronics products. There were 2595 companies participating in the exchange and almost 70000 visitors took part in the exhibition. The exhibition is being conducted every two years alternatively to the Productronica. There were participation of various companies dealing with different types of electronic goods like the displays, connectors and interconnects, semiconductors, automotive, sensors, passive components, assemblies and sub-systems, wireless, embedded systems, power supplies, test and measurement etc. It is one of the best places where we come to know about different technologies, products and even test the new product to confirm our expectation. The fair also is business area where companies come for advertising and selling their products. I was able to visit stalls of 37 companies dealin g with power supply devices and gathered informations which I was able to present on the topic wireless transfer of power. Certain companies were doing research works on this topic but were not able to introduce their products because certain defects were yet to be cleared before manufacturing. Companies visited RRC Solutions The company was established in the year 1989, with the excellent management has become one of the leading companies in the supplier of power supplies and battery chargers. It has a good platform for the professional applications in medical, industrial, military and consumer products. The company has good wealth of expertise engineers creating new and innovative ideas. The company has its branches in various locations of the world with its headquarters in south west Germany. Its branches are located in USA, Japan, China, Hong Kong etc The companys products involve battery chargers, power supplies, integrated system solutions, products

Cultural Differences in Parent-Child Communication Essay

Today’s children face more diversity than their parents were when they were at the same age. The cultural differences in how the parents deal and communicate with their children around the world are a great challenge. Parent’s involvement in their children’s literacy and communication either in school, home or community will be effective through communication strategies and awareness about cultural differences (Alvarez, 2000). The support of parents is one of the critical components of their children’s communication development. The effort, support and parent’s expectation for their children’s way of communication can be of great help to understand the complicated and diverse cultural differences. The socio-cultural differences vary from language, ethnicity, poverty level, sex and education that could affect the children. Cultural differences are a great challenge to prove that parents can communicate with their children and improve their behavior in dealing with other people. There are variety of reasons why parents resist and exclude themselves in children’s literacy, school activities and communication process. The number of cultural differences increases with the number of children in school, and children with full support from their parents can achieve more especially if the school setting resembles their home language. Every parent must have face-to-face interaction with their children. This is a way to establish a trusting relationship with them. Discussion Since people from different culture and race exist, parents must inform and orient their children about individual beliefs and different way of living and why does it happen. By acknowledging the differences in culture is a way to clear children’s obscured judgment of other cultures and encourage an unbiased opinion (Alvarez, 2000). As responsible adults, parents have the responsibility to open their children’s thought without prejudice about cultural mix. The couple themselves may be from different cultural backgrounds but if they do not allow this difference to get in the way of their relationship, this can allow their children to experience the mixture of different cultures (Hoover-Dempsey, 2002). It is the responsibility of parents to educate their children on matters of religion and spirituality. Nowadays, there are children who are smarter than their parents. These children can throw various questions that expect intelligent answers from adults. In teaching children about cultural differences, respect and tolerance about one’s practice and belief is important. Most of the children will emulate their adult figure and will act the same way as their parents. Parent’s effort in learning cultural differences will help their children to gain diverse awareness. Parents must have the initiative to get to know their neighbor, encourage their children to befriend other children in their school and community, and invite some friends to join dinner at home. Despite the difference in physical attributes (i. e. , hair, skin color, height, and beliefs of individuals, children must be trained to respect everyone and perceive them as a person. Understanding one’s culture does not mean acceptance but matter of respect regardless of their similarities and differences. Parent’s responsive behavior and desire to educate their children about other people’s beliefs, practices and values could promote secure attachment. There are different factors which influence individual beliefs, values and practices like parent’s intuition, the accustomed parenting practices, previous attachment practices to their parents, parental norms and accepted culture in their family, religious belief and the generation changes (Madriz, 2000). There are no consistent patterns of parental communication within each cultural group. There are predominant beliefs and practices brought by parental instinct which do not involve assistance and learning from professionals or literature but could provide security and protection during the course of child development. This type of parenting is not always reliable and can be derived from different sources. Many parents learned their communication through formal and informal means depending on their country of origin. One good example of cultural differences that takes place is when children feel lost when he enters the school premises for the first time. These children have little confidence on how to communicate with other children. However, they gradually follow consciously or unconsciously the cultural trends in school until they become accustomed to the culture. The presence of parental support like sharing their past school experiences to their children is one powerful way of informal learning. It is not necessary that parents must have an answer for every child’s inquiry but it is important to let them have awareness for everything. Parents can be of great help to their children by providing them support and making them feel comfortable to stay in school despite having no relatives, cousins, playmates and other house members that could attend to their immediate needs (Allexsaht-Snider, 2000). Parents need to talk to their children about the enjoyment brought by coming to school as they meet different people from different culture. The care and love provided by every parent to their children will equip them with confidence. Parents vary from being over-protective, loving, unmindful of their children, abusive both physically and emotionally and may not portray a typical model of ideal parents. Other parents do not have desire to act like parents despite the challenges of taking this role (Bloom, 2000). Trying to have positive outlook for their kids may be difficult due to internal conflict. They keep on fighting on how they were brought up by their parents. These negative patterns of parent’s growth will affect their child rearing process and security attachment. Although there is recognition and awareness of being parents to their children, they need to overcome their negative patterns of growing by showing great affection that they missed when they were still a child. There are different accepted parenting norms influenced by cultural differences with extent pressure to conform to their norms. Parents who strongly believe that their cultural practices must continue despite having unsupportive environment will affect their way of communication with their children. Parents keep on teaching their children the strong interwoven tradition of their religious beliefs, values and practices, the important role of their cultural spirituality greatly affects their way of living and dealing with other people that can be passed through their children and offspring. Living in another location induces stress on the parents and children, especially when difference in cultural background is present. It strongly affects their children due to their fear of rejection, lack of support for their beliefs and practices, and fear of how to ingrate their culture to the present situation. Example of this stressful cultural difference includes the Yugoslavians who were trapped in the midst of ethnic conflict due to religious differences. Other examples include the Muslims from Africa who do not eat pork, the Asian nations that swear not to fight, and the religious sects who do not want to consume drugs for their sick loved ones (Allexsaht-Snider, 2000). Parents having difficulty transmitting and enforcing their values become even stricter in ensuring that their own cultural traditions will prevail. Children are usually surrounded and mingle with peers who do not have the same cultural orientation. The risk and fear of being voted out by their fears bring them unspeakable dilemma (Allexsaht-Snider, 2000). As parents, communicating with their children about cultural differences they must inflict to them that their trust is to mould them as good children with moral and responsible obligation to their family, school and community (Allexsaht-Snider, 2000). The clash of cultural differences must not be a form of struggle in their day to day living but rather help them to become flexible and protective of their own culture. From child’s birth to his seven years of existence in the world, most parents play and rear their children. From seven years to fourteen years of life they guide them to follow their cultural practice. From fourteen to twenty one years of life towards adulthood, parents must be a friend to their children (Joyner, 1996). They keep on guiding but respecting their own prerogatives in life. Regardless of countries of origin, families can gain practical learning experiences that can transfer to their children and let them feel the challenge of changes in their lifestyle with guidance. By understanding the children’s priority with compassionate guidance they can be ready to occupy a space in this world with respect to cultural differences and share their own cultural and religious beliefs and practices. Within cultural groups, an individual may experience diversity but the important thing is for them to recognize the dynamic features of every culture (Allexsaht-Snider, 2000). Changes may take place from generation to generation brought by influx of younger generation ideas and countries global position. However, the essence of cultural differences lies in the benefits derived from diversity learning. During the past, most children would be quietly sitting in their living room while their parents are entertaining visitors and must be involved in their conversation. Those were the days of traditional parenting. At present it is necessary for parents to encourage their children to get involved in conversation and be confident enough to share and learn new ideas. It is just right to keep certain traditional beliefs and practices but by adding some new and positive ideas can help them in adjusting to current environment. Reflecting and evaluating the parenting style, values and practices will enable the children to keep the best values, give up the not so good ones and adopt to new ones. Though parents can keep on talking about their old practices and beliefs about cultural differences, it is just right to adopt new practices, beliefs and values with an intention of improving and benefiting their children. Conclusion Cross-cultural learning experiences differed but it is important not to fall into the trap of being left and keep on living based on past cultural beliefs, values and practices. Giving children the affection, attention and respect despite of being young are significant aspect of parent-children relationship, community involvement and extended family interaction. No individual learns from one person alone. Each individual is connected by their day-to-day interactions with others. The children should be taught to communicate in positive manner with others as this can help them in their self-development (Edwards, 2001). It is great to know that children will obey their parents not because of fear or control but because of their choice to share their own opinion and be respectful in dealing with other people. Teaching children to respect everyone regardless of cultural differences is a way of helping them to grow (Allexsaht-Snider, 2000). The deep and enduring connection of parents to their children creates happiness at home with their own freedom of expression towards healthy child development. References Alvarez. T. (2000).

An examination of that context of mostly violent suggests that portrayals of death and dying representations functions of social typing and control and tend, serve symbolic of on the whole, to conceal the reality and inevitability the event.George Gerbner is Professor of Communications and Dean of The Annenberg School of Communications, University of Pennsylvania.

A symbol system is an artifact par excellence. It is totall y invented to serve human purposes. It can serve these purposes only if those interpreting it know the code and can fit it into a symbolic context of their own. They must share the rules of the invention and the interpretative strategies by which it should be understood. Symbolic narrative, a story, has two basic elements of invention: fictive and selective. Selective invention is factual narrative such as news.Presumably true events (facts) are selected from an endless stream of events. A narrative is invented to convey some meaning about the selected facts as interpreted in a previously learned framework of knowledge. Fictive invention is fiction and drama; the â€Å"facts† are invented as well as the narrative. (Selection is of course involved in both. ) The function of fictive invention is to illuminate (literally to embody and dramatize) the invisible structure and dynamics of the significant connections of human life. It is to show how things work.Invention that can onl y select events but not create them must be more opaque; it can only show what things are but rarely why or how they work. The full development of the connections between events and human motivations and powers requires the freedom and legitimacy to invent the â€Å"facts† in a way that illuminates the otherwise hidden dynamics of existence. In this totally invented world of and fictivesymbols-selective without some purnothing happens pose and function (which need not be the same). Let us use as example the world of television which we have studied for some years. This discussion also applies to other media and cultural forms, with the difference that television is the generally non-selectively used universal storyteller of modern society. It is, therefore, more a symbolic environment than a traditional medium. People are not born into the world of television. They are selected or created for a purpose. The purpose is usefulness to the symbolic world (called news values or st ory values) that the producing institutions and their patrons find useful for their purposes.More numerous in both news and drama are those for whom that world has more uses-jobs, power, adventure, sex, youth, and all other opportunities in life. These values are distributed in the symbol system as most resources are distributed in the society whose dominant institutions produce most of the symbols: according to status and power. Dominant social groups tend to be overrepresented and overendowed not only absolutely but also in relation to their numbers in the real population. (For example, men outnumber women at least three to one in television and most media content. Minorities are defined by having 1. The long-range project was first described in my article on â€Å"Cultural Indicators: The Case of Violence in Television Drama† in the Annals, Vol. 388, March 1970. The most recent report, including a description of methodology, appears in George Gerbner, Larry Gross, Nancy Si gnorielli, Michael Morgan, and Marilyn Jackson-Beeck, â€Å"The Demonstration of Power: Violence Profile No. 10,† Journal of Communication, vol. 29 (Summer 1979). 66 THE ANNALS OF THE AMERICAN ACADEMY less than their proportionate share of values and resources.In the world of television news and drama, this means lower underrepresentation numbers, less usefulness, fewer opportunities, more victimization (or â€Å"criminalization†), more restricted scope of action, more stereotyped roles, diminished life chances, and general undervaluation ranging from relative neglect to symbolic annihilation. DEATH IN NEWS AND DRAMA Death in such a context is just another invented characterization, a negative resource, a sign of fatal flaw or ineptitude, a punishment for sins or mark of tragedy.It is always a reminder of the risks of life, cultivating most anxiety and dependence for those who are depicted as most at risk. In other words, death is one feature of the more general functi ons of social typing and control. Obituaries are the Social Register of the middle class. Even a â€Å"nobody† of modest status and power (i. e. a person of no symbolic existence in the common culture) becomes a â€Å"somebody† if the flicker of his or her (and it's mostly his) life can leave its final symbolic mark of existence in the obituary column.Death in the news is a tightly scripted scenario of violence and terror. Murders, accidents, â€Å"body counts† and catastrophies scatter a surfeit of impersonal corpses in ghoulish symbolic overkill across the pages of our family newspapers and television screens. By the time we grow up, we are so addicted to this necromania of our culture (and we are not alone), that its constant daily cultivation seems to add to a morbid sense of normalcy. Yet it is all well (if unwittingly) calculated to cultivate a sense of insecurity, anxiety, fear of the â€Å"mean world† out there, and ependence on some strong protec tor. It is the modern equivalent of the bloody circuses in the Roman empire's â€Å"bread and circuses† that were supposed to keep the populace quiescent. At the center of the symbolic structure of death is the world of stories invented to show how things and drama. The most work-fiction massive and universal flow of stories in modern society (and history) is of course television drama, most of it produced according to the industrial formulas developed to assemble large audiences and sell them to advertisers at the least cost.That is a world in which practically no one ever dies a natural death. Assembly-line drama generally denies the inevitable reality of death and affirms its stigmatic character. Violent death, on the other hand, befalls 5 percent of all prime time dramatic characters every week, with about twice as many killers (many of whom also get killed) stalking the world of prime time. The symbolic function of death in the world of television is thus embedded in its structure of violence, which is essentially a show of force, the ritualistic demonstration of power. THE STRUCTURE OF VIOLENCEAND POWERDominated as it is by males and masculine values, much of the world of prime time revolves around questions of power. Who can get away with what against whom? How secure are different social types when confronted with conflict and danger? What hierarchies of risk and vulnerability define social relations? In other words, how power works in society. The simplest and cheapest dramatic DEATH IN PRIME TIME 67 demonstration of power is an overt expression of physical force compelling action against one's will on pain of being hurt or killed, or actually hurting or killing.That is the definition of violence used in our studies of television drama. Violence rules the symbolic world of television. It occurs at an average 10-year rate of 5 violent incidents per hour in prime time and 18 per hour in weekend daytime children's programming-a triple dose. Violen ce as a demonstration of power can be measured by relating the percent of violents to the percent of victims within each social group. That ratio shows the chances of men and women, blacks and whites, young and old, to come out on top instead of on the bottom.Conversely, it shows the risks of each group to end up as victims instead of victors. Table 1 is a summary of these â€Å"risk ratios† based on annual samples of prime time and weekend daytime (children's) programs major dramatic characters, a total of 3,949, from 1969 through 1978. It shows for each of several demographic and dramatic groups the ratio of violents over victims (including killing) and of only killers over killed (or the other way around) within each group. It also shows the percent of characters in each group involved in any violence as either violents or victims (or both).For example, of the 415 children and adolescent characters studied, 60. 5 percent (65. 0 percent males and 49. 1 percent females) were involved in violence. Of the males, victims outnumbered violents by 1. 69 but killers outnumbered killed by 3. 00. In other words, for every 10 child and adolescent violents there were about 17 victims, but for every 10 killed there were 30 killers in that group of characters. Overall, 63 percent of all characters were involved in some violence. For every 10 violents there were 12 victims, but for every 10 killed there were 19 killers.However, as we have just seen, involvement in violence and its outcome-as with values and resources-is not randomly distributed. Some features of the distribution of violence as a demonstration of power can be illustrated by selecting a few risk ratios from the Table, showing how these victimization rates define a hierarchy of risks within which the depiction of dying (and killing) is embedded. A hierarchy of risks Combining prime time and daytime characters, we find that victimization rates define a social hierarchy of risks and vulnerabilities.For e very 10 characters who commit violence within each of the following groups the average number of victims for white men is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. nonwhite men is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. lower class women is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ young women is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. nonwhite women is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. old women is †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 12 13 17 18 18 33 If and when involved in violence, women and minorities, and especially young and old as well as minority women characters, are the most vulnerable. Now let us look at dying (and its dramatic counterpart, killing) in that context.We can compute a lethal pecking order by relating the number of killers to the number of killed within each group. Unlike violence in general, killing eliminates a character and must be used more sparingly, either as curtain-raiser or as the â€Å"final solution. † Therefore, in most role categories, there are more killers than killed. â€Å"Good† m en, the TABLE 1 RISK RATIOS': MAJOR CHARACTERS IN ALL PROGRAMS (1969-197 ALL CHARACTERS INVOLVED IN VIOLENCE VIOLENTVICTIM RATIO KILLERKILLED RATIO MALE CHARACTERS INVOLVED IN VIOLENCE VIOLENTVICTIM RATIO K N NAll Characters Social Age Children-Adolescents Young Adults Settled Adults Elderly Marital Status Not Married Married Class Clearly Upper Mixed Clearly Lower Race White Other Character Type â€Å"Good† Mixed â€Å"Bad† Nationality U.

DEATH IN PRIME TIME 69 male heroes of prime time drama, are at the top of the killing order. For every 10 â€Å"good† men killed, there are 38 â€Å"good† men killers. Next are young men and American men; for every 10 young males killed, there are 22 young male and American male killers. The killed-killer ratio of all white males is only slightly lower: 21 killers for every 10 whi te males killed.In other words, if and when involved in some fatal violence on prime time television, â€Å"good,† young, American and white males are the most likely to be the killers instead of the killed. They kill in a good cause to begin with or are the most powerful, or both. Women do not fare so well. Their most favorable ratio is 20 killers for every 10 killed, and that goes to foreign women. The second highest female kill ratio goes to â€Å"bad† women: they kill 17 characters for every 10 â€Å"bad† women killed. Next are middleaged women who kill 16 for every 10 killed.Thus women who tend to kill, kill much less than men, have relatively more lethal power when they are foreign, evil, or past the romantic-lead age, than when they are â€Å"good,† American, young, and white, as is the case with men. Their killing is more likely to be shown as unjust, irrational, and â€Å"alien† than is killing by men. At the very bottom of the lethal peck ing order are old women who get involved in violence only to get killed and â€Å"good† women who get killed 16 times for every 10 killers. Old and â€Å"good† women get into violence mostly as sympathetic (or only pathetic) victims, rousing male heroes to righteous (if lethal) indignation.Next in line are lower class men, lower class women, and old men. For every ten killers in each group there are, respectively, 11, 10, and 10 killed. Unlike those of greater ability to survive conflict or catastrophy,older and lower class characters pay with their lives for every life they take. Provocation and retribution In general, then, as can be seen on the Table, the pecking order of both mayhem and killing is dominated by men-American white, middle class, and in the prime of life. At the top of the general order of victimizers are â€Å"bad† women, old men, and â€Å"bad† men, in that order.The presence of evil at the top of the power hierarchy suggests the drama tic role of villains provoking heroes to violent action. Heading the ranking of killers over killed are â€Å"good† and other majority-type males. We can begin to discern not only the provocative role of the â€Å"bad† but also the retributive function of the â€Å"good† and the strong. Lowest on the dramatic scale are women, lower class, and old people. Of the 20 most victimized groups (both total violence and killing), all but three are women. Old women are at the bottom of the heap of both the battered and the killed. Good†women are among the charactersmost likely to be both general and fatal victims of violence ratherthan the perpetrators. â€Å"Good† men have power as indicated by their heading up the killer-killed list; â€Å"good† women, on the other hand, end up near the bottom of the power hierarchy. When it comes to violence, â€Å"good† are the strong men and the weak women of the world of television. Dying on television is a violent retribution for weakness, sin, or other flaw in character or status. It is part of the social typing and control functions of centralized cultural production.Our research has found that heavy viewers (compared to light 70 THE ANNALS OF THE AMERICAN ACADEMY viewers in the same social groups) derive from their television experience a heightened sense of danger, insecurity, and mistrust, or what we call the â€Å"mean world† syndrome. It can be conjectured that the symbolic functions of dying are part of that syndrome, contributing not only to a structure of power but also to the irrational dread of dying and thus to diminished vitality and self-direction in life.
