Free Essays on Imagery Of The Lion In Agamemnon

Imagery of the Lion in Agamemnon In Aeschylus’ Agamemnon, symbolism is prominent throughout the play, and it is used to represent the feelings of the characters. The Greeks concentrated heavily on symbolism in their everyday life. Worshippers of many gods, the Greeks obviously felt the need to allow one thing to represent another. Their gods were symbols of things on earth that they did not understand; using these gods enabled them to make sense of certain things and/or feelings. Therefore, it comes as no surprise that Aeschylus, an obvious product of his idealistic time, would incorporate this belief of symbols into his writing. Agamemnon is overloaded with symbolism; on of the most prominent is the animal imagery. Humans who cease to control themselves legitimately tend to be personified as animals. This statement is justly proven throughout Agamemnon through the use of several different animal symbolisms. One in particular is the lion. The lion can be seen as a powerful animal, as well as be noted for its slyness and deceitful tendencies. This â€Å"king of beasts† is known to be a bloodthirsty creature that is ruthless and threatening. Lions are also said to be protective, social beasts, and this seemingly contradictory trait is mirrored in some of the characters. In Agamemnon, Aeschylus makes known the similarities between many of the characters and this beast through their common lion-like qualities. In contrast to the play, another characteristic of the lion is that they will often abandon or leave their cubs to die of starvation for their own self-gain. This is ironic to the play because the character most referred to as a lion is Clytaemnestra, the mother. Her motivati on for killing her husband is because he has sacrificed the daughter. This is one paradoxical trait that is not shared between Clytaemnestra and the lion. To the contrary, Agamemnon sacrificing his daughter is in concordance with the behavi...

Biography of James K. Polk, 11th US President

Biography of James K. Polk, 11th US President James K. Polk was president during the Mexican American War and the era of Manifest Destiny. Learn more about the 11th president of the United States. James K. Polks Childhood and Education James K. Polk was born on November 2, 1795, in Mecklenburg County, North Carolina. He moved with his family at the age of ten to Tennessee. He was a sickly youth who suffered from gallstones. Polk did not begin his formal education until 1813 at the age of 18. By 1816, he entered the University of North Carolina and graduated with honors in 1818. He decided to enter politics and also was admitted to the bar. Family Ties Polks father was Samuel, a planter and landowner who was also a friend of  Andrew Jackson. His mother was  Jane Knox. They had been married on Christmas Day in 1794. His mother was a staunch Presbyterian. He had five brothers and four sisters, many of whom died young. On January 1, 1824, Polk married Sarah Childress. She was  well-educated and wealthy. While first lady, she banned dancing and liquor from the White House. Together, they had no children. James K. Polks Career Before the Presidency Polk had focused on politics his whole life. He was a member of the Tennessee House of Representatives (1823-25). From 1825-39, he was a member of the U.S. House of Representatives including serving as its speaker from 1835-39. He was a great ally and supporter of Andrew Jackson. From 1839-41, Polk became Governor of Tennessee. Becoming President In 1844, the Democrats were having a difficult time getting the necessary 2/3 of the vote to nominate a candidate. On the 9th ballot, James K. Polk who had only been considered as a Vice Presidential candidate was nominated. He was the first dark-horse nominee. He was opposed by Whig candidate Henry Clay. The campaign centered around the idea of annexation of Texas which Polk supported and Clay opposed. Polk received 50% of the popular vote and won 170 out of 275 electoral votes. Events and Accomplishments as President James K. Polks  time in office was eventful. In 1846, he agreed to fix the boundary of the Oregon territory at the 49th parallel. Great Britain and the United States disagreed about who claimed the territory. The Oregon Treaty meant that Washington and  Oregon  would be a territory of the U.S. and Vancouver would belong to Great Britain. Much of Polks time in office was taken up with the  Mexican War  which lasted from 1846-1848. The annexation of Texas which had taken place at the end of  John Tylers time in office hurt relations between Mexico and America. Further, the border between the two countries was still disputed. The U.S. felt that the border should be set at the Rio Grande River. When Mexico would not agree, Polk prepared for war. He ordered General  Zachary Taylor  to the area. In April 1846, Mexican troops fired on the U.S. troops in the area. Polk used this to push forward a Declaration of War against Mexico. In February 1847, Taylor was able to defeat the Mexican army led by  Santa Anna. By March 1847, U.S. troops occupied Mexico City. Concurrently in January 1847, Mexican troops were defeated in California. In February 1848, the  Treaty of Guadalupe Hidalgo  was signed  ending the war. By this treaty, the border was fixed at the Rio Grande. By this means, the U.S. gained California and Nevada amongst other present-day territories amounting to over 500,000 square miles of land. In exchange, the U.S. agreed to pay Mexico $15 million for the territory. This agreement reduced the size of Mexico to half of its former size. Post Presidential Period Polk had announced before taking office that he would not seek a second term. He did retire at the end of his term. However, he did not live much past that date. He died only three months later, possibly from Cholera. Historical Significance After Thomas Jefferson, James K. Polk increased the size of the United States more than any other president through the acquisition of California and New Mexico as a result of the Mexican-American War. He also claimed Oregon Territory after a treaty with England. He was a key figure in Manifest Destiny. He was also an extremely effective leader during the Mexican-American War. He is considered to be the best one-term president.

Life of galileo lalilei Research Paper Example | Topics and Well Written Essays - 1000 words

Life of galileo lalilei - Research Paper Example His views that the Earth is not the center of the Universe therefore created more resentment and opposition than the work of any other scientist during that era. However, despite the opposition of the mighty, the ideas of Galileo prevailed and the world was able to develop a modern system of astronomy and physics which has evolved and culminated into the current model of science. Society has therefore benefited a lot from his work and how it really shaped the way science as a whole has evolved over the period of time. This paper will therefore argue that Galileo Galilie was a rebel scientist and his ideas and work has greatly changed the way is now progressing. The overall context of his work will also be presented. Galileo Galilie Born in 1564, Galileo became one of the most important scientists in the history of science who laid the foundations for the modern science. During his early life, he seriously considered to become a priest however, due to his father’s insistence he went on to study in the University of Pisa for a medical degree. However, he was not able to complete his degree and went on to study mathematics instead of medical sciences. It was during that era that his overall interests for the mathematics and other physical sciences started to develop. He was later appointed on different teaching assignments and his real contribution towards science started to emerge during the early part of the 17th century. At University of Padua he was able to develop different scientific theories and contributed not only towards the pure fundamental science but towards the applied science also. Galileo therefore is also famous for his contributions for inventing new technology and setting the foundations for technological innovations. (Hilliam) During that time he went on to make some of the most important discoveries and invented many equipment which allowed scientists to perform mathematical calculations relatively easily. It was also during that period that Galileo started to evolve as one of the most established scientists of his time. The conflict between the Galileo’s discoveries and scientific faith however, was believed to be in direct conflict with the established religious orthodox thought of that time. Over the period of time, Galileo through his hard work produced scientifically accurate theories however the unacceptability of his ideas despite the fact that Galileo was a religious person all through his life. It was also because of his religious beliefs that he could not take up his illegitimate daughters and asked them to spend most of their lives in church. (McNeese) He was accused of heresy and was later sent for inquisition which he survived only after retracting from his earlier position thus giving Church time to establish and re-establish its own authority. Scientists as Rebels It is argued that scientists always remained rebels as throughout the entire history of Science; scientists have uncovered or disc ussed issues that were considered as unacceptable as per the norms of the society. This tendency seems to continue till today where scientists, despite their innovation and creativity are still considered as agitators because what they discuss and achieve may take time to get the acceptance

Political communication Essay Example | Topics and Well Written Essays - 1000 words

Political communication - Essay Example Since the flu affects every individual regardless of gender, cultural background or economic status, the campaign is directed to all the people in United Kingdom. Special attention is also given to people coming in the country because they may be bringing the virus just like in the case of the two infected persons confined in a hospital in Scotland who arrived from Mexico (Wake Up Britain, 2009). The campaign aimed to warn people about the dangers of swine flu and at the same time educate them on how to prevent getting infected or infecting others if they suspect they already have the virus. The government used different media such as flyers (Charles, 2009; Department of Health, 2009; NHS & DHSSPS), radio and television broadcast as well as the internet to communicate the information. They hit the right target audience because with the characteristics of the flu, no one is invulnerable. The flyers contained complete information about swine flu and extended more information by giving numbers which people could call in case they need to be educated more about the virus (NHS & DHSSPS, 2009). However, it should be considered that not all who receive leaflets really read them completely. The television advertisement (Department of Health, 2009) can be considered to have effectively relayed the message to the different kinds of people by using models of different races genders and ages. It was short, clear and concise. However, the campaign was quite short and fails to expound on the seriousness of the advice being given. Nevertheless, this could also be understandable because when the campaign was done, everybody seemed to have been well-informed about the swine flu already. Perhaps it could be safe to say that the television is the most accessible medium of information because it is often used for relaxation and people do not need to read what is presented on the screen.

Identification After Gender Essay Example for Free

Identification After Gender Essay Time episode Fionna and Cake and reading Berengier of the Long Ass, the expectations of genders are exposed through the reversal of roles in both of these pieces. The characters in these stories clearly demonstrate the expectations that certain males and females must negotiate in order to expose the problems when there is labeling of certain genders. Judith Butlers analysis of gender is that it is performative- meaning that nobody really is a gender from the start; after watching the video and reading the text for this exercise, t is clear that Fionna and The Knight expose the misconceptions of gender throughout societies today. In our society today there are certain notions that many people have about what are right and wrong for males and females to wear, think, and act. There are certain things that are expected out of males- a toughness about them, an attitude that declares them as the man of the house- that is unfairly labeled upon every male in our society. Females are expected to be the ones who constantly act girly and let the males do everything involving manual labor- this is an unfair label that is placed upon every female in our society. The video that Judith Butler takes part in is an example of a certain female who does not believe in conforming with the problems of the rest of our society- taking a stand against the normal ideas of the public. Judith Bakers ideas are expressed throughout Fionna and Cake and Berengier of the Long Ass, when Fionna , The Lady, and The Knight expose these misconceptions by swapping roles; The Lady and Fionna act as the males, while Prince Gumball and The Knight act as the females. The idea that Fionna and The Lady act as the males in these stories define the problem that our society has when it omes to the definition of males and females. There are certain expectations that must be fulfilled when it comes to being seen as a male or female, but in these two pieces (video and story), the main characters both reject the expectations, or try and fulfill them unsuccessfully. In the Adventure Time episode Fionna and Cake Fionna and Prince Gumball act as their opposite gender in many ways. Throughout Fionna and Cake Fionna refuses to completely fulfill these expectations that are placed among most females. Fionna goes through the majority of the video as a tomboy who would rather carry weapons in her person than make-up. However, by the end of the video she adapts to the normal expectations for females by dressing up in a dress and trying to flatter Prince Gumball. In order for Fionna to expose the expectations of certain genders, Fionna goes to the extreme limit when trying to act as a boy; for there is nothing more manly for a human-being to do than to save someones life. Fionna saves Prince Gumball, which in turn creates a relationship between the two that was not there before. It becomes evident that there is a gender swap in this video when Fionna is the one who is catching Prince Gumball when he falls from the ceiling. o infatuate Fionna, portraying the inner-man of Princess Ice, and getting the inner- woman out of Fionna. Fionna Justifies the ideas of Judith Butlers by showing the audience that it took awhile for her to find her preferred gender- switching preferences multiple times between the beginning and end of the video. Fionna proves that any female can be happy doing male-type things, but also can be happy with a man, which goes against the norm of being a tom boy. By the end of the story it is clear that Fionna chooses to give up the girly personality that is expected mong women, while consistently being herself, and attracting the Prince of her dreams. In the reading Berengier of the Long Ass, The Knight and his Lady successfully pull off an epic gender swap that The Knight would not be very proud of. Throughout the beginning of the story the Lady constantly criticizes her husband for being lazy and not being a chivalrous Knight. Because she questions the Knights manhood, the Knight forces himself to make a change. The Knight then tries to fulfill the expectations of Knights in our society by creating fake battles in the forests to impress his wife. Because he does a bad Job of faking his fatigue and injuries after these fake battles, the wife begins to catch on to his tricks. The wife then follows him to the next battle realizing that what he was saying the whole entire time was a fraud. Butlers applications to gender being performative comes into play here, because the Knight tries so hard to be a man -that his life turns upside down because of it. The Knights wife then brings back another guy to the house, knowing that because her husband is a woman in her eyes, he will not even think about doing anything to harm her. When the Knight realizes that his attempt at conforming to the publics interpretation ofa knight has failed, he feels as though he is a failure- for the only important in most knights life is the chivalrous way in which they live. A Knights expectation is to be the most brave, genuine, and honest guy of all; however, in this case the knights wife was more of a knight than he was. The Knight in this story tried to adapt to the expectations that are naturally placed on him, and instead of adapting he completely failed at his attempt. Most people are better off being their atural-selves than trying to fulfill the expectations that others place on them. After analyzing Fionna, Prince Gumball, The Knight, and his wife, it is obvious that being yourself leads to the most happiness between one and their partner. Fionna maintains her inner-boy personality and ends up being the happiest girl in the world. The Knight tries to change his personality and ends up watching his wife hang out with another man. Judith Butlers ideas really make sense after analyzing these characters because of the way in which characters can reject the expectations of their gender and be completely happy because of it.

The Economy of Israel :: Israeli Palestinian Economies Economics Essays

What the parties will gain: the economic aspect of the agreement. The second redeployment agreement can serve as a springboard for both the Israeli and Palestinian economies, separately and together. The greater beneficiaries, politically, economically and propaganda-wise, are the Palestinians. The agreement removes restrictions and solves hardships that have prevented growth and development in the Palestinian Authority. The influence of the Israeli economy has been lessened and will be expressed mainly in the change of atmosphere. In the coming months, the three countries -- Israel, Jordan and the Palestinian Authority -- will be considered by the international business community to be more stable and less dangerous and thus more attractive for investment. If investments arrive is another matter, depending on the global economic situation. President Clinton has promised Israel "security aid," but no economic aid, to implement the agreement. The amount of the special aid will reach hundred of millions of dollars, Jerusalem believes. The expense must be approved by Congress. Will the second redeployment agreement have the power and spirit to pull the Israeli economy out of its recession and calm the foreign currency market? Doubtful. Much more is needed to do that -- an economic policy devoted to growth, a comprehensive Israeli-Palestinian-Arab peace, as well as a renewal of the concept of a "New Middle East Economy." What are the economic advantages for the Palestinians from the second redeployment agreement? In a sentence, they will be less dependent on Israel and will stand more firmly on their own feet. * An international airport in Gaza will serve tourists, visitors and Palestinian importers and exporters, without Israeli intervention. * Safe passage between the two parts of the PA will, over time, enable the free flow of work, capital and initiative. * Industrial zones -- the first at the Karni crossing -- will promote Palestinian high- tech, which is just starting out. Investors may come. * A port at Gaza, though not economically viable, will give a feeling of independence and remove the economic stranglehold that the Palestinians complain about. Construction work on the port will provide employment for many Palestinians. * A presidential visit by Bill Clinton in Gaza will be an important signal to the American business community to invest with the Palestinians; the president usually brings plenty of businessmen to such shows of friendship. * The United States will supply the Palestinian Authority with additional economic aid, totaling hundreds of millions of dollars.

More specific to the negative effects on you and your social skills, the effect on relationships personal and professional, and beauty in an image obsessed world. The term â€Å"social media† is an oxymoron. There is nothing social about tapping into cyberspace. The addictive activity doesn’t promote real interaction with other human beings. It isolates individuals. Engaging in social media is the opposite of being social. The dictionary defines this as â€Å"relating to or involving activities in which people spend time talking to each other or doing enjoyable things with each other.† Being social means enjoying the companionship of friends and associates. It means forming cooperative and interdependent relationships, preferring community to living alone. But those who live for social media connections don’t need community in the traditional sense. They can text, email, tweet, and post by themselves. They can connect with Facebook â€Å"friends† and never leave home. Actual  face-to-face conversation with actual eye contact is unnecessary. Instant messaging makes personal contact irrelevant. The book Unfriend Yourself: Three Days to Detox by Kyle Tennant â€Å"Now let’s be clear I have Facebook account and I check it 3 to 5 times daily so I haven’t given up on social medial entirely but what I have come to see is that one of the dominant cultural metaphors of our time is not to be trusted nor is it to be lauded. In fact it may be our generation’s greatest enemy. Though social media promise us relationships and community, they may in truth be promising a lie. â€Å" This could clearly be linked to the dangers of false relationship online social media can bring also can be known as cat fish. We as human being need real human interaction to have any type of communication or social skills. An article called -The Negative Effect of Social Media on Society and Individuals by Brian Jung, says that social media gives us a false sense of connection and decreased productivity in the workplace. A False Sense of Connection According to Cornell University’s Steven Strogatz, social media sites can make it make it more difficult for us to distinguish between the meaningful relationships we foster in the real world, and the numerous casual relationships formed through social media. By focusing so much of our time and psychic energy on these less meaningful relationships, our most important connections, he fears, will weaken. Decreased Productivity while many businesses use social networking sites to find and communicate with clients, the sites can also prove a great distraction to employees Wired.com posted two studies which demonstrated damage to productivity caused by social networking Social media is causing us as humans to have very little to no real interaction. I think Roberta M. Gilbert says it best in her book about human interaction called â€Å"Extraordinary Relationships: A New Way of Thinking about Human Interactions†. She says that It would be difficult to overestimate the  importance of human relationship. If love does not make the world go, then surely relationships do. Now im sure we all know or someone have heard of the effects of social media and how if creates an unhealthy body image.

Robotics

Introduction Robotics has revolutionized the way industries operate, the way items are built, and the way society lives. Robotics is a fairly new technological advance that has made lives easier, and has provided a breakthrough for many operations and businesses. In a way, robotics is the future for businesses as well as the future of mankind. Like any other type of technology, robotics can be used in various industries, has advantages and disadvantages, and has a long history of how it came about.There are many aspects of robotics to be considered which include educational fields that one can choose, and the types of applications and industries robotics is found in. Safety is an important concept and part of robotics, especially because of its complexity. Being well educated in the field of robotics can play an important role on safety as well. This field can greatly reduce the workload and can increase the productivity in many companies, no matter how big or small. Robotics is the future, and embracing it will help in the future success of businesses.History of Robotics The actual word robot was made popular by an author in his 1921 play. This author claims that his brother was the inventor of the word, which comes from the Czech word â€Å"robota† meaning servitude. Robots were first used in factories such as industrial companies, where these would fix machines in order to handle manufacturing tasks that facilitated the production and assisted humans in their everyday tasks. Robots such as industrial robots that used artificial intelligence have actually been around since the 60’s.After the 1950’s computers along with robotics started to increase in popularity as well as complexity and numbers as technology also began to advance. In 1961, the first industrial robot was built to work on the General Motors assembly line, and this machine was conceived in 1954 by George Devol and was called Unimate. The name was given because the robot was manufactured by a company called Unimation. Unimate is to this day remembered as the first industrial robot ever built. After the first robot was built, many others started to come around, and in 1971 the first icroprocessor called 4004 was created by Ted Hoff at Intel. Many other creations began to follow such as programming language called Prolog, which became the basic language in the field of artificial intelligence, then came the first industrial robot with six electromechanic axes, then the silver arm, capable of replicating human hands. Currently, robots are used to monitor outer space. In April of 2001, the Canadarm2, which was attached to the space station, was launched into orbit. This robot was a much larger and more capable version of a previously used arm.Another break though in the robotics field made it to stores in 2002. The Roomba, a robotic vacuum cleaner manufactured by the company iRobot became quite popular during this time. The most recent robotic creation was the Robonaut 2, which is the latest generation of astronaut helpers that was launched into the space station on the STS-133 mission. This is the first humanoid robot in space. Some of its features included showing engineers how robots actually behave in space so they could work on upgrades and possible advances that would assist spacewalkers perform their scientific work.Google also came out with robotic vehicles, called Google driveless cars, which became famous in 2010. These robotic vehicles had drivers behind the wheels in case of an emergency, and drove to various places while taking pictures of their surroundings. Unimate Google Images4004 Google Images Canadarm2 Google ImagesThe Roomba Google Images Robonaut 2 – Google ImagesGoogle’s Driveless Car Google Images Advantages Robotics as any other industry and profession has advantages and disadvantages. Business decisions usually come with pros and cons especially when it coms to automating the rocess of production by using industrial robots. Companies need to first take time and consider all the facts before deciding to add robots to their departments, especially when these can bring advantages and disadvantages in the process. Some of the advantages that robots can bring to companies is the fact that the quality of work is excellent. Industrial robots have the capabilities to improve the quality of production. Some of the applications performed by robots are more precise than those performed by humans and are more consistent in their quality as well. This igh level of quality and consistency is harder to obtain in any other way besides using robots. In production of products by using robots the speed of their outputs has a dramatic impact in the overall production of products. Robots are built to work at constant speeds without needing sleep, vacations, breaks, and they even produce more than any human worker. Safety is one of the other advantages found in the use of robots. Robots increase the safety in the workplace as these can perform in dangerous environments and hazardous settings, giving the opportunity to umans to move the supervisory roles and away from hazardous environments. Robots also have the advantage of proving savings for companies. Being able to provide a safe workplace, robots can bring financial savings to companies as these will incur less worker compensation fees, no healthcare or insurance payments, and robots also perform at higher levels with a fraction of the effort. Disadvantages Robots also have disadvantages that need to be considered. Investing in a robot can be costly, especially if the business owner has a budget to work with. The cost of automating the roduction by using robots needs to be calculated into the business’ financial budget. The maintenance of the robot should also be calculated to avoid future surprises or bills. When it comes to robots, programming and interaction are required, as with new employees hiring and trai ning is also a requirement. This programming and interaction can become costly depending on the time invested. Robots can also provide a safe work setting for employees, as they take the place of them in hazardous settings, but they can also bring safety problems. Their only presence can be the cause of hazard for workers as well. Advantages |Disadvantages | |You can send them to very dangerous places |You need to get people trained to fix them if anything wrong | | |happens | |You can make them do you're job for you |Need a very intelligent crew | |They are more accurate than humans Eg no shaking when in a |They can ruin peoples lives Eg Take their job away from them | |very important surgery, puts every screw in fabricating a car| | |etc. | |Can do jobs 24/7 |They are very expensive to make | |Can guard without being tired just keep doing the same thing |You need the right materials to make them, that could be very| |24/7 |rare | |No need of nutrients |If you make a very amazi ng robot with amazing quality and it | | |brakes, it might be very hard to fix | |You can program them to make them do exactly what you want |They can be very hard to program | |them to do | | |They can not harm you unless they are programmed to |They can reproduce but it could cost money for the materials | |Can work with out doubts Eg when you think â€Å"what do i do |They can reproduce but it could cost money for the materials | |now†? | |They can lift very heavy things |You need highly trained people to make them | | |They can not recharge themselves | (â€Å"Advantages and disadvantages,† ). Industries Robotics falls into three major industries including manufacturing, service and defense. These industries will also generate jobs such as technical engineering, software, testing and many others. Because robotics is such a complex field, and no one person can manage knowing every aspect of it, this is known to be a collaborative field. Basically, robotics requi res a lot of team work and discipline to achieve all the required tasks in providing a successful product. This is a great advantage as segments of robotics seem to be growing fast. One industry in particular as been the service industry, which has seen tremendous growth over the last decade. Robots are being used more frequently in manufacturing, where these help create jobs. Robots also help control quality of products and maintain that quality high. Currently, the highest percentage of robotics is seen in the United States, where about 60 percent of the service industry and 80 percent of the military industry are located. The largest manufacturers of robotics, however, are still in Germany and Japan. Service Industry Google ImagesMilitary Industry Google Images Robotics and Education Currently the robotics industry is growing rapidly, and if people do not already own a robot, they will very soon.This industry is growing in various ways such as size and sales, as well as creating growth around itself. It has been found in recent research that the robotics industry is expected to generate over one million new jobs over the next five years. One great way to get involved in the field of robotics is to sign up for the First Robotics Competition. This is a good first step, especially for those under 18 years of age. By getting involved in the competition, you can learn every aspect of robotics, the different product life cycles, and also gain experience in the field. College is another great way to learn about robotics, as many institutions offer classes and degrees in robotics.Robotics is a very complex field, and it as multiple industries that it’s a part of. The robotics industry can offer employment to a wide range of people, even if their specialties do not include a degree in this field. Many people who have science degrees, physics, or even electronics degrees are employed in the field of robotics. Software is a part of robots that is not usually vi sible, yet engineers that design these software are very important and there are many jobs available for them. The future will be driven by software designers, and those who specialize in computer science. If one is passionate about robotics, it is recommended to take a course in a robotics elated field to learn more, and to find the different paths you can take in this field. By doing so, one can meet other people interested in robotics and share ideas and interests. Some universities do not offer specific robotics courses, but you can learn about robotics by taking engineering classes as well. Some of the subjects that will allow you to learn more about robotics include computer science, mechanical engineering, and electronics engineering. It is always a good idea to spend time taking small courses to see if this field is the right career path, instead of diving into a three to four year degree without being sure it’s the right choice.

With new developments in the robotics field, one of the problems that engineers are facing is safety. Safety is a concern that every industry has with their employees, and is now becoming a concern with robotics as well. One of the solutions that have arise regarding safety has been to prevent the user from coming into contact with the robot by using physical barriers to do so.While studying robot-human interaction, which is known as HRI, it has been found that removing these barriers will allow people to and robots to work together and cooperate in order to perform the required tasks. Robot systems that are able to perform HRI tasks will be considered as being safety-critical complex systems because of their size, behavior, functionality, and can even cause damage to their surroundings and to their operators. One of the objective when it comes to designing robots is to have the engineers work to achieve safety. Even if engineers design a safe robot, it an be hard to prove its safety by merely testing it. The Future of RoboticsOne aspect in which robotics has revolutionized the way we live has been the invention of the mobil phone. This invention changed the communication industry when it was introduced in the early 90’s. This simple device has sparked demand for wireless communication as well as portability in other devices. Knowing how robotics has changed the way we communicate, it can be predicted that robotics will have a great impact on the future as way especially in the areas of battery life and weight, artificial intelligence, and swarm robotics. Battery life is essential for mobil devices, and it can be seen as it is the largest part of the device, and the heaviest. In the uture, power sources will be reduced to allow a smaller device with longer battery life. The second area in which robotics will impact is artificial intelligence, or AI. So far many advances have been made in thi s field, but there is still much to be done. Currently, AI systems have been created to generate logic routines at basic levels. In the future, AI software may be able to think or even act like humans. Swarm robotics is the last important area, and it refers to controlling multiple cooperating robots. This basically means that multiple robots will be able to do various tasks and at the same time be cooperating directly or indirectly to complete that task.This will help in employee a large amount of robots to complete one major task. Mobil Devices Google Images Artificial Intelligence Google Images Swarm Robotics Google Images Robots vs. Humans Robots are known to have skills that cannot be matched by humans. In some cases, robots perform one function, but in others robots can take on various tasks that will take the place of several employees. One good example is how electric shavers used to be assembled in the old days, by using hundreds of factory workers who perform this task by using only their hands. Now, these same tasks are performed by robot hands. These robots can perform the work at igher speeds than humans can, three sifts a day, 365 days a year, and without vacation, breaks, or sick days. The future of business is in robotics. Companies are now wanting to work with the robotics systems that electronics giants such as Apple are currently using. Because robots are coming down in price, and at the same time growing in sophistication, it is believed that jobs will be lost. The success of robotics has jeopardized many jobs as so many tasks can be performed at a fraction of the time, higher quality, and at a fraction of the price. Even robot manufacturers have stated that in several applications robots are already more cost-effective than people. One ay to show this was seen in a company where a $250,000 robot replaced two machine operators, making $50,000 per year, and over the 15-year life of the system, the machines yielded $3. 5 million in labor and productivity savings. Robots are known for being a faster assembly line, and this is one of the main reasons they have been replacing so many factory workers, and giving companies more of a competitive advantage and savings. Conclusion Robotics has become a great part of society’s lives, and has even become essential in developing specialized tasks that need the constancy and preciseness of robots. Handling certain tasks could take excess amount of money and time that if performed by humans alone could ruin ompanies as they would not be competitive in the market. Robots provide us with the assistance needed to get the job done faster, and in a more productive way. This is the future and being a part of it makes it definitely better. References Wikipedia.

Free Essays on South Beach Diet

South Beach Diet The South Beach Diet isn’t low-carbohydrates or low-fat. Instead, it explains to someone considering starting the South Beach Diet how to rely on the right carbohydrates and the right fats. These good carbohydrates and right fats are taken in so you can lose weight, lower your cholesterol, reduce your risk of heart disease and diabetes, and get rid of cravings without feeling hungry. The South Beach Diet allows you to choose the right carbohydrates and the right fats, which allows you to go throughout the day without being hungry all the time, and when you do eat your portion sizes wont be nearly as big. Good Carbohydrates versus Bad Carbohydrates. Much of a persons excess weight comes from the carbohydrates we eat, most commonly when the highly processed carbohydrates found in baked goods, breads, snacks, SOFT DRINKS, and just about every other favorite snack food. These carbohydrates are considered bad carbohydrates because industrial processing removes the fibers from food, and once these fibers are taken from the food, the way our body metabolizes them changes significantly, and very much so for the WORSE! One reason that excess weight is bad is that it impairs the insulin in our body to do its job of processing fuel (fats and sugars) properly. This condition is called insulin resistance. As a result of excess weight, the body stores more fat than it should, especially in the midsection, which is extremely hard to get rid of instead of just keeping it off. In the South Beach Diet plenty of animal proteins made up for the cut in bad carbohydrates. According to the author of South Beach Diet, Arthur Agatston, M.D. †lean meat did not have a harmful effect on blood chemistry.† Doctor Agatston also stated that â€Å"even egg yolks are good for you, which is contrary to what we once believed.† Chicken, turkey, fish, nuts, low-fat cheeses, and yogurts are all considered â€Å"Good Fats,† and are recommen...

Carpenter Bees and How to Get Rid of Them

Carpenter Bees and How to Get Rid of Them Carpenter bees can be a real nuisance. They resemble large bumblebees and can be found buzzing around dwellings and other structures where they like to build their nests. Every year, they cause millions of dollars in  damage to dwellings by tunneling into decks, porches, and other wood structures. They can also be aggressive, especially during mating season, and will fly very close to human beings and even bump into them. Fortunately, they rarely if ever sting people and their nests can be removed. Carpenter Bee Basics There are several species of carpenter bee in the United States, but the most common one is the Virginia carpenter bee (Xylocopa virginica). These bugs are found throughout the Southeast but range as far as Connecticut to the north and Texas in the west. Carpenter bees range in size from about 5/8 of an inch to 1 inch and look very similar to bumblebees, but theyre not the same.   Bumblebees (genus Bombus) nest in the ground, usually in abandoned rodent nests, and live in social communities. Carpenter bees (genus Xylocopa) are solitary bees that burrow into wood. You can differentiate the two by examining the dorsal (upper) side of the abdomen. If its shiny and hairless, its a carpenter bee. A bumblebee, by contrast, has a hairy abdomen. Both are considered beneficial insects because they are  excellent plant  pollinators. Therefore, you should avoid eliminating these insects unless absolutely necessary. Carpenter bees usually live for about one year. Each new generation is hatched in the late summer, emerging from nests in August and September to grow and feed, pollinating flowers as they go  before  settling in for the winter and hibernating. Survivors emerge in April and May to mate. The female carpenter bee excavates a tunnel for her offspring. In each brood chamber, she stores food and lays an egg. Having reproduced, adult carpenter bees die off in July, leaving the new generation to continue the cycle when they emerge a month or so later. Most people encounter carpenter bees during April and May when theyve just emerged to mate. During this time, male carpenter bees tend to hover around nest openings, looking for receptive females. It can be rather unnerving being around them, as the males will also hover aggressively around people who approach the nests. They may even fly right into you. Despite this tough act, male carpenter bees cannot sting. Female carpenter bees can sting, but almost never do. How to Identify Nests If you see a bee emerging from a hole in the ground or within a structure, thats a good indication that youre looking at a carpenter bee nest. To be certain,  look at the entrance holes. A carpenter bee makes an entrance hole slightly bigger than her body, or just about  ½ inch in diameter. The first inch or two of the tunnel is usually made against the wood grain. The bee will then make a right turn and extend the tunnel another 4 to 6 inches in the direction of the wood grain. Carpenter bees will often eliminate their waste before entering their nest, so you might see yellow stains on the surface of the wood, just below the entrance hole. Stavros Markopoulos / Getty Images Though they burrow into wood, carpenter bees dont eat wood like termites do. Since their nest tunnels are limited in size, they rarely do serious structural damage. However, because such excavation requires a lot of energy on her part, a female carpenter bee will often prefer to refurbish an old tunnel to digging a new one. If carpenter bees are allowed to tunnel in the same structure year after year, however, the cumulative damage can be significant.   How to Control Carpenter Bees Your best defense is a good offense. Carpenter bees prefer to excavate untreated, unfinished wood. You can prevent carpenter bees from nesting in the first place by painting or varnishing your homes exterior. If an infestation has occurred, you will need to use an insecticide to eliminate the carpenter bees. Many professionals recommend sprays or dust, which can reach the interior surface of the entrance holes. Apply the pesticide at dusk, when carpenter bees are less active.   For the insecticide to work, the bees much come in contact with it as they crawl through the entrance hole of the nest. Apply the appropriate insecticidal dust in the spring, just before adults emerge to mate. Once you see the bees emerge, wait a few days before filling in the nest holes with wood putty or filler. If you didnt apply the insecticide before the spring adults emerged, you will need to treat the nests in the spring, and again in late summer, when the next generation of adults is foraging. In the fall, seal the nest holes with steel wool, then close off the hole with putty, wood filler, fiberglass, or asphalt.   A professional pest control service is your best choice, especially if you have a large infestation because theyll have specialized tools that can reach deep into crevices. However, if you want to do it yourself, any name-brand insecticide formulated to kill flying insects should work. If youd prefer to use a natural remedy, there are several, including boric acid,  Diatomaceous earth, and citrus spray. You can also contact  your local extension office  to find out which insecticides are effective and legal for use on carpenter bees in your area. Sources Bamabara, Stephen and  Waldvogel, Michael.

The Use of Isotopes in Medicine Essay Example | Topics and Well Written Essays - 1500 words

The Use of Isotopes in Medicine - Essay Example These are the radioactive and stable isotopes. Bodamer and Halliday (2001, p. 444) define radioactive isotopes as those whose nucleus is unstable. Because of this, radioactive isotopes have a tendency for spontaneous decomposition, a reaction which involves the release of radiation. During the decomposition of a radioactive isotope, a helium nucleus is released, a process which leads to the stabilization of the isotope. On the other hand, a stable isotope does not have a tendency for spontaneous decomposition and as a result, these isotopes resist various forms of chemical alterations. Radioactive have been used widely used in medicine as agents of diagnostic processes. This essay gives a critical analysis ad discussion of the various uses or applications of isotopes in the field of medicine. Many chemical elements contain isotopes. Radioisotopes are often products of artificial combination of protons and neutrons. Artificial production of radioisotopes often employs protons and neut rons which do not exist in nature (Ruth, 2009, p. 536). There are a total of 1800 radioisotopes including those which arise from the decay of thorium and uranium in their primordial states. There are a variety of ways in which radioisotopes can be produced or manufactured artificially. These include neutron activation which is the commonest way of producing radioisotopes. This is done within a nuclear reactor. In addition, some radioisotopes are produced within a cyclotron in which deficiency of neutrons within a nucleus is achieved through artificial introduction of protons (Bodamer and Halliday (2001, p. 445). The artificial manufacture of radioisotopes is aimed at meeting their application in medicine. The radioisotopes used in medicine are known as radiopharmaceuticals. The following section describes three major applications of radioisotopes in medicines with the justification on why specific radioisotopes are used in the management of various medical processes. The disadvantag es associate with the use of isotopes is also provided later in the essay. According to Ruth (2009, p. 537), isotopes are used in nuclear medicine to provide diagnostic information which is used by physicians to diagnose various medical conditions. This is achieved through the imaging of organs such as bones, thyroid gland, liver and heart to determine their functioning. Prvulovich and Bomanji (1998, p. 1140) demonstrates 90% of the application of isotopes in medicine if for diagnostic procedures. Technetium-99 is the most commonly used radioisotope for medical diagnosis. Ramamoorthy and Binukumar (2010, p. 46) say that technetium-99 is used widely as a radioactive tracer. This isotope is commonly used because it is detectable within the body through the use of specialized medical equipment such as gamma cameras. Technetium-99 is releases gamma rays and this explains why gamma cameras are able to detect it within the body. More importantly, technetium-99 is relatively safer in diagn osis as compared to other isotopes. This is due to the fact that it its physical and biological half-life is short. As a result, it decays within 24 hours of exposure to the body. This provides sufficient time for the quick detection of chemical equipment while it keeps the exposure of the patient to the radiation as low as possible (Bodamer and Halliday (2001, p. 446). This demonstrates why this isotope is commonly applied in medical diagnosis. Prvulovich and Bomanji (1998, p. 1143) explain that isotopes are also commonly used in therapy.
