Time and Nanotechnology Essay Example for Free

Time and Nanotechnology Essay Do you believe in technology? Or do you think that all inventions of scientists are worthwhile for humanity? Of course, lots of these inventions are helpful and useful. Also, some of them have created new periods in past. They played a big role for coming modernity. However, there are some inventions that seem very effective but they have brought new problems for humanity and environment. Especially, at the beginning of an invention, people don’t realize that it will become big problem. Nowadays, people are taking notice of this kind of things. Nanotechnology is one of these inventions which are needed to be discussed from point to point. Today, there are some people who believe that nanotechnology is dangerous; however some scientists think that nanotechnology has great benefits because it helps people to invent new things for the future. Nanotechnology is a huge area which gives opportunity for other technologies to create better products. With the benefits of nanotechnology, it will be easy to develop new things. First of all, I want to explain a little bit what nanotechnology is. Nanotechnology is taking up the control of matter on a molecular scale. It deals with very little structures which is 100 times smaller. At this scale, properties of products can be changed, giving one the ability to create new things such as create more precise, cleaner, better, stronger and more durable products. For example, today, there are some kind of battery which is produced with nanotechnlogy, much more durable than before. In addition, in the future, it will be easy to invent new products and machines because nanotechnology will play vital role on manufacturing. According to Angelo (2007), â€Å"Nanotechnology promises to fundamentally change the way materials and devices will be produce in the future† (pp. 256). This can be change the future totally. Nanotechnology has contributed so much to advances in many different areas. Lots of technologies are affected from new developments in nanotechnology because these developments open a new period for others. Medicine is the most important area which is affected from nanotechnology. Today, there are some diseases which have not any treatment and cause lots of death. To illustrate, cancer is one of these diseases. But with the usage of nanotechnology in cancer treatments, scientists found a way to treat people. Also, it looks to be more developments on medicine in the future. Another important area is electronics. Like nanotechnology, electronics is very important area for new developments. Nanotechnology has contributed so much to electronics. According to Miller et al. (2004), Nanotechnology has effect on the electronic tools and systems and it is getting possible to develop on computer processing, memory and data storage and demonstration technology (pp. 24). With the usage of nanotechnology, there are lots of materials which are very small, strong and faster than before. The last important area is textile industry. New developments of nanotechnology also play vital role on this industry. Today, new textile products are more durable to heat, UV ray and chemicals because of the changing the structure of products. In addition, it seems to be more advance in the future.

The company’s clients and the overall day-to-day activities, the employees involved themselves in to keep the company running.

Classical Theories Describing Trade Between Different Nations Economics Essay

Classical Theories Describing Trade Between Different Nations Economics Essay The following essay encompasses a review based on two of the popular Classical Theories describing the fundamental basis for trade between different nations. The foremost part comprises of a treatise about the ways in which Ricardos law of comparative advantage is superior to Smiths theory of absolute advantage. The middle part is a discussion over the gains from trade arising as a result of comparative advantage. The final part talks about ways in which a less efficient country can export anything to a second nation that is more efficient in production of all commodities. In what way was Ricardos law of comparative advantage superior to Smiths theory of absolute advantage? It is imperative to understand Ricardos law and Smiths theory in order to be able to highlight superiority of former over the later. Smiths theory of absolute advantage declares that A country benefits by producing only those products in which it has absolute advantage, or can produce using fewer resources than another country. (Cavusgil, Knight, Riesenberger, 2008 ) Adam Smith was of the view point that since one nations import is the export of another nation so it was not viable for all countries to become wealthy concurrently by following mercantilist view. He asserted that if all countries were to focus only on products in which they have absolute advantage, they could export them to other countries and in return import those products in which they do not have absolute advantage in producing. He believed that this free trade will benefit all countries simultaneously. Ricardos law of comparative advantage states that It can be beneficial for two countries to trade without barriers as long as one is more efficient at producing goods or services needed by the other. What matters is not the absolute cost of production, but rather the relative efficiency with which a country can produce the product. ( Cavusgil, et.al.2008) David Ricardo argued that international trade will benefit countries even if one nation has an absolute advantage in production of all commodoties. He believed that if a country could produce a product more efficiently than a country which was self sufficient in producing the same product but with less efficiency then it is better to import that commodity from the country producing it more efficiently. Though Smith successfully established the case for free trade, he did not develop the concept of comparative advantage. Because absolute advantage is determined by a simple comparison of labor productivities, it is possible for a nation to have absolute advantage in nothing. (www.encyclopedia.com) The above excerpt quite answers the way in which Ricardos law has an advantage over the Smiths theory. The key point of the selection is quite evident: What if a nation has absolute advantage in nothing? Does it stop importing products from other nations because it has nothing to export? This is where David Recardos law of comparative advantage is superior to Smiths theory. It is more comprehensive in terms of associating specialization with opportunity cost. Unlike Smiths theory which is completely based on absolute advantage, Ricardos law of comparative advantage generates hope for nations that are technically on the back foot by entailing that they can involve in international trade even if their labor output in all commodities is less than that of a developed country. In todays scenario, an example could be of Pakistan exporting cotton products to United States and importing military guns, tanks and missiles. (http://internationaltrade.suite101.com/) United States can produce cotton products too but relatively less efficiently than Pakistan. On the contrary, United States has a relative advantage in making military products. According to Ricardos law of comparative advantage, United States is benefitting from Pakistans efficiency in making cotton products whereas Pakistan is benefitting from United Statess efficiency in making military products. The above example justifieses the win-win situation as was proposed by Ricardo. If United States was to choose to grow cotton on its land and make its own cotton products, it could possibly have done that, less efficiently though. This signifies that if Smiths theory was implemented, Pakistan would have nothing left to trade with the United States. How do gains from trade arise with comparative advantage? Based on Ricardos law of comparative advantage, gains from trade arise in terms of increased world output for any commodities that any two countries import and export from each other. No one country wastes extra time and money producing the same product less efficiently which another country can produce more efficiently. Let us assume that Country A produces a commodity more efficiently and therefore has a relative/comparative advantage over Country B for that commodity which might be able to produce that same commodity but less efficiently. Suppose Country A exports its commodity to Country B in exchange for importing something which it cannot produce as efficiently. Both Countries A and B utilized comparative advantage to get what they wanted. Both countries gained from each others area of expertise. This assumption outlines outcome of Ricardos law of comparative advantage. Another example could be of trade between Saudi Arabia and Australia. Both nations utilize their natural advantages to gain from trade. Saudi Arabia has ample Oil which it exports to Australia. In return it imports Bauxite (finest quality of coal) from Australia. In this way, both nations are benefitting by exchanging what they have in excess with what they do not have or which may be there but more difficult to extract. Australia might be having reservoirs of Oil available deep within its Oceanic boundaries but the cost of extracting them would be too high. Labor costs are much higher in developed countries such as United States. These countries mostly hire government owned or government supported firms providing cheap skillful labor in developing countries such as China to get their task accomplished. What did they each gain from trade arising with comparative advantage? Developed countries gain: Cheap labor hence more profit. Developing countries gain: Employment. So it becomes a win-win situation. United States gets its product manufactured at a much lower cost than it would have back in United States. China gets employment. How can a nation that is less efficient than another nation in the production of all commodities export anything to the second nation? Ricardos law of comparative advantage demonstrates that a nation that is less efficient than another nation in the production of all commodities can still export to the second nation. That is because what matters is not the absolute cost of production, but rather the ratio between how easily the two countries can produce the products. (Cavusgil, et.al.2008) Ways in which Ricardos law plays its role in helping a less efficient nation export commodities to a more efficient nation have been discussed in the previous part of question. A less efficient nation can also export to the more efficient nation by implementing and incorporating competitive advantage in its international trade policies. A nation can attain competetive advantage by coming up with innovative advancements, by targeting industries for development, providing low-cost investment, reducing taxes, and by investing in emerging technologies to take up the future. Policies should be encouraging for local and foreign investments such as tax free business in Dubai. Industrial clusters should be promoted which often act as a nations export platform. Michael Porters famous Diamond Model outlines the way a country can increase its competetiveness: ( Cavusgil, Knight, Riesenberger, 2008, pp-104) Conclusion: As is evident from the above essay, Ricardos law is superior from Smiths theory because it justifies that trade is still possible between two countries even if a country does dont have absolute advantage in anything. The above arguments also prove that comparative advantage is advantageous to both the trading nations as a result of utilizing relative advantage in import and export. Besides Ricardos law of comparative advantage, competetive advantage supported by Michael Porters Diamond Model can help a less efficient nation develop industrial clusters so as to be able to export to a more efficient nation.

As part of the cell cycle, mitosis is the nuclear division of replicated chromosomes by the disconnection of the replicated chromosomes to form two genetically identical daughter nuclei. Escorted by mitosis is commonly the process of cytokinesis. The cytokinesis process entails a dividing cell splitting into two, resulting in the subdivision of the cytoplasm into two cellular suites. The process of mitosis can take place in either a haploid (23 chromosomes) or a diploid (46 chromosomes) cell. Before a cell can be ready for a mitotic division it must primarily undergo its interphase stage. Following the interphase stage several other stages come into play. These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During each specific stage certain sequences of events take place that assist to the completion of the division. During interphase, cell growth, DNA replication, separation of centrioles and protein synthesis takes place. This phase is acknowledged to being the most extensive period of the cell cycle thus signifying the stage in which the cell devotes th...

Baby Boomers Essay -- essays papers

Baby Boomers During the Great Depression and World War II many Americans delayed marrying and having children because of the poor economy. The number of marriages and births soared after the war. Many older couples who had delayed having children began having them when the war ended. This increase in births among both younger and older American couples created the Baby Boom Generation. This large group of people born in the U.S. from 1946 to 1964 amounted to 76 million children. Those born during this time make up approximately 36% of today’s population (Deutsch). What impact has this had on the economy? Read on to see how the baby boom generation has affected the economy and what will happen as they retire. This generation has had a huge impact on the economy due to its sheer size. At first there was a crunch at hospital maternity wards. When the boomers reached school age, schools became overcrowded, forcing towns to build additions. By the time they were entering senior high the cities and towns were expanding. New office buildings, hotels, apartment complexes and stores were springing up everywhere. When they reached college age, American Higher Education had to expand. Large enrollments along with inflation pushed college costs higher. When they started families of their own and became homeowners it drove real estate prices up. As they passed through the life cycle, these shortages soon became surpluses. An example being the collapse of the real estate market in the late1980’s (Sullivan). We can expect a large demand for retirement housing, elder care and finally the funeral industry as the Boomers continue their life cycle. Marketers have followed the boom generation for decades, producing items that appealed to them as children, teens and young adults. With more money in their pockets than time on their hands, today’s baby boomers are dining out at an all time high. Now it is people over the age of 40 who have the resources to purchase big-ticket items. Today the engine that is driving our economy and our stock market is due to the lopsided demographics present right now. The coming of age of discretionary spending is allowing people to buy that SUV, boat, computer, etc that would have been put off in the past (Income). The economy is sensitive to the Boomer generation’s desire for a luxury lifestyle. As they look toward retiremen... ...grams for children, while a new state agency was created to represent the needs and concerns of older citizens.† (Sullivan). The baby boom generation has had a profound effect on the American economy at each stage of their life starting with the demand created for goods, then filling the labor market. Now we’ll have to wait and see if their retirement will cause the doom predicted by some or create the marketplace godsend predicted by others.

Lending a Helping Hand

Lending hand can mean a variety of things for many people. It can mean help to get out of a financial bind, coming alongside another for a time of grief, or just being there for somebody. But most of us lend a hand to another for the purpose of seeing how one can help another in a specific situation.Especially in time when what one knows can help in the predicament of another. One of my reasons seeking admission in your program is to do just that.In my seven years in the New York City Department of Education, one of my duties has been to conduct visitations to the parents of children that have proven to difficult. These children usually come from backgrounds and stations in life that would other people ask â€Å"Why Bother? But that is where the motivation comes in for me to seek admission into your program. It's to make people understand the lives of these children are worth something.In this line of work, it is imperative that I can get a backgrounder of the children's behavior fr om the parents or guardians of these children. This would allow me to better assess the patterns of the child in relation to his various environments.Factors such as school and social life, I believe, have a great bearing on the behavior of these children. But with the knowledge I already possess, I should have a better chance at the reformation of the child should I gain entry into your program.When the case is usually presented, some people are often times just ready to give up on these children. Many people would just rationalize that these children are born to be at the low rungs of society, ending up either as beggars or criminals. But my vocation is not just to give up on them. I try hard to get them on the right track. But what is exactly the right track?For them, the first step in finding the path is talking to them. It's a big step for them to open up on the reasons that they drop out of schooling. The parents, too, have a large part in the reformation of the child. I make it a point to challenge the parents of these children to be positive influences on the lives of these children.Some may think that what I do is tiring, exasperating and down right frustrating. At some times, I would tend to agree. The many times that I talk to children and parents would tend to frustrate even the best of people. Especially when you see the efforts, the sheer amount of it, just end up in smoke. But to me, it's just not a job. If I sound a bit on the ethereal, I do find what I do to be a calling of sorts.Usually, people would connote a calling to be of a grander design. A calling would tend to make people think of going on some mission in life, away from civilization and the perks and benefits of this life to be with the down trodden and less fortunate. But how does getting children to go back to school be a calling? For me, it is a calling.If your office would office would consider my personal circumstance, most of what is apparent that apart from the house visits th at I regularly conduct with the parents of truant children, most of the facts are in the area of clerical, administrative or research work. But these credits, I believe, would prepare me in earnest to help more children if I get accepted into your program. How? I believe that your program is looking for students not just good in academics, but learners and doers.Brain knowledge and experience are, to me, two vastly opposite ends for learning. Just getting into program with just the expressed desire to acquire more brain knowledge is not a trait that I would want to carry into my field. Yes, accumulating knowledge is important in correctly doing the task that is set before an individual. But I believe that with my experience and the knowledge that I know I will gain in your program will allow me to be better at my calling.It is also mentioned in my personal circumstance that I also assist in the education of children with special needs. The children in this area are of need of extra care and attention. This is another area that I would like to improve on with the knowledge that I would gain should I gain entry into your program. But what would be the relationship of mostly clerical and administrative work in the final output?Academics, I believe, are an essential part in the execution of any program designed to help any individual. Without the knowledge gained in school, it would be difficult to be effective in any endeavor one has set out to do. But is the attainment of a degree of academic knowledge the answer in helping these children? Should that be the only basis?My advantage would be that in addition to the knowledge that I know I will gain in the event that I am accepted into your program, that knowledge will be accompanied by years of first-hand experience that I already possess.The many instances and incidents of helping and aiding children, whether to get back into school or helping them in finding suitable alternatives to formal schooling, or explain ing to the parents of special needs children their individual education plans, should serve me in good stead if I am chosen to get into your program.Why the passion in helping these children? I must also point out that I am a mother of two young boys, with one of them, my 5 year old suffering from a speech disability. This everyday first hand experience of seeing my child being helped along as he gets better from his impairment, has bolstered my resolve and conviction that I can be of greater use to other children if I combine my years of experience with further study available through your program. It is my fervent desire that should be humbly among those accepted into your program.
