Electro Magnetic Fields Essays - Electrical Engineering,

Electro Magnetic Fields Electricity is the building block of our society. Now more and more we are becoming dependent on electricity from computers to microwaves, electric power is what keeps our society running. Something that no one thinks about is Electro- Magnetic Fields or (ELF's). While these ELF are being ignored slowly they are becoming a silent but deadly killer in our society. Scene cancer and illness are becoming so common people are slowly coming around about what ELF's are and what if anything can be done to stop or slow down the effects of ELF's on our families and friends. Their maybe only few solutions to stop ELF's infiltration on our society and only one or two alternatives were found to slow the fields so they don't affect our health. " In 1995 leaked a draft report by American Scientific committee conducted that millions of people face an increased risk of cancer and other degenerative diseases from exposure to fields from power lines, power plants and electrical appliances."(Perry 1) With that quote we can see that this isn't a new issue to our society, but yet more people are clueless about the effect of electro- magnetic fields on their health and about the health of their children. The most common reaction of people when warned about ELF's is that " we live far enough from the power lines that it isn't going to affect us." This reaction is so common, but people don't realize that it's not just caused by power lines and power plants it's also inside our homes. The most common things in our homes are secondary causes not the power lines. Items such as microwaves, computer screens, toasters, electric stoves, blenders and cellular telephones. With these things in our homes are becoming so common that everyone has them and it affecting our lives. " In the last 10 years the rate of cancer is becoming the most common cause of death."(Perry 1) Though sunlight's Ultra Violet Rays (UV's) take the top spot for causing cancer ELF's are attributed to 35% to 40% of childhood cancers and 10% to 15% of adult cancer. Electric companies have a common reaction to these instances by denial. As we are becoming more dependant on electricity, power transmissions are entering our lives in greater strength. The power companies solution to the power demands is to increase the amount of high-voltage power lines. The reason for high-voltage lines is "over great distances high-voltage lines must be used in order to minimize losses, but in those losses it's causing an increasing amount of cancers and sickness due to the use of these high-voltage lines."(Plaz 229) This just shows the ignorance of the consumers ant greed of the power companies for not accepting the responsibility of protecting the people. In the sickness mentioned in the previous paragraph, what its called is "electrical sensitivity (ES)." "ES is a form of chronic environmental illness triggered by exposure to ELF's."(Perry 2) The symptoms are common among to days illnesses, but are or could be caused by ELF's. They are "headaches, dizziness, buzzing and nausea."(Perry 2) Everyone suffers from these ailments and if people you know suffer from these things, a look should be taken at their living space especially in children. Common areas that can be blamed is the kitchen due to all the appliances and the bedrooms near power lines or power plants. Though their are measures that can be taken to decrease these illnesses, but people are not informed to ELF's so no measures are taken. Children and pregnane women are the major concern for ELF's. The reason that children are susceptible to ELF's are their immune systems are not fully evolved and therefore their white blood cells are not at full composed. Not having a fully developed immune system leaves them open for the increased risk of cancer and ES. This was proven in a study done by the New York utility industry of power lines. "This a five million dollar project headed by Dr. David Carpenter of SUNY Albany concluded that up to 30% of all childhood cancers may be linked to ELF's"(Safe 1) In pregnane women another study done by independent lab's in the United States and Ontario Canada said that an "increase in cases of SIDS"(Perry 1) and"incidents of adverse reproductive outcomes and birth defects in newborns"(Ontario 1) are associated with high instances of ELF surroundings and in the homes. With all this proof I've found it's hard to imagine that no actions are being taken to reduce and stop

Prepare yourself for your upcoming internship

Prepare yourself for your upcoming internship Are you on the cusp of starting a new internship? If so, then congratulations- this can be an amazing opportunity for self-discovery and an important step in your lifelong career journey. Simply put, internships are great ways to explore your professional strengths and weaknesses, and can help you target your interests and passions- hopefully helping to guide you onto the career path that best suits you. That said, not all internships- or interns- are created equal. While some make every effort to put their best self forward and approach the internship as if it were an ultra-important full-time job, others take a less serious approach- and take a guess which type of intern typically fares better? That said, how have you decided to approach your upcoming internship? If you’re smart, you’ll prepare yourself in advance as much as possible in an effort to make a great impression. Who knows- if you really nail it, you just may find yourself weighing a great new job offer at the end of it!Consider using the following plan of attack to help ensure that your internship starts off strong.Do your homeworkBefore your first day at your new internship, make sure you know everything there is to know about the company you’re about to join. Most companies these days have a robust online presence, so take advantage of available information online. Not only will it help you do your job more effectively, it will likely impress the folks you’ll be working around. It may even serve as a springboard for bold new ideas that you can use to wow your new boss- and who knows what can happen from there?Also do your best to be fully aware of what your role in the organization will be, what will be expected of you from day one, and what your team or department does within the broader context of the organization (ideally, you used the interview process to have all of these questions answered). This will help reduce any awkward surprises on day one of your internsh ip, and also set you up to impress your new bosses when you’re able to hit the ground running when you first arrive.Know yourselfAs mentioned before, internships are a great way to learn about your strengths and weaknesses and discover what you’re interested in and good at. That said, you already know a great deal about yourself and can use what you know to your advantage at your new position. Make sure your strengths are on full display while at work. Are you a whiz at spreadsheets? Then do your best to set yourself up to work on any spreadsheets that your department utilizes. Have countless presentations in class made you a PowerPoint pro? Then volunteer to work on any PowerPoints that you discover are being worked on while at your internship. Not only will you come across as a team player who’s willing to go the extra mile, you’ll hopefully impress others with your abilities.In contrast, try to work on building your skills in your week areas subtly whi le at your internship. Take small opportunities to test yourself and confront new challenges- before long you’ll be more well-rounded and capable at work than ever before!Get professionalThis one often gets overlooked by interns, and they wind up paying the price when they arrive at work and aren’t completely ready. Get into a professional mindset before your internship starts and you’ll be setting yourself up for success. This includes getting an appropriate work wardrobe ready, practicing your workplace etiquette (here’s where a parent, mentor, or experienced friend or family member can really help), getting any supplies you might need, and even practicing getting up early for several days beforehand- you’ll be surprised by how a little advance planning to get yourself into professional mode can really benefit you in the long run.If you’re on the cusp of starting a new internship, it can be a really exciting time- as long as you prepare sm artly. Use the strategies and advice presented here to be your best starting on day one. Soak it in- this is the time for you to explore a profession or a company to see if it’s a great match. Use it wisely!

Discussion of a current marketing problem Essay

Discussion of a current marketing problem - Essay Example This gives them instant access to tangible video copies (not streaming video) that even Netflix could not provide without a day or two wait for the mail system to deliver videos. As such, subscribership began to drop as Netflix was not providing cost incentives to avoid brand defection by once loyal consumers. This led to media coverage that was very negative in which investor confidence began to fall, along with outlook for continuing subscribership and revenue growth, which plummeted the stock from $236 in September 2011 to only $66 in December 2011. Media coverage showing many negative factors about a business model has very substantial impact on consumer perceptions about a brand. While all of this negative publicity was occurring, Netflix was also realizing that its operational costs were steadily increasing, therefore the business would have to raise prices in order to offset these concerns. The operational cost increase factors included royalty fees paid to many different film production companies that hold intellectual property rights on many of the products offered by Netflix. With growth in streaming video online, the costs of operations increased from $180 million annually in 2010 to $1.98 billion in 2012 (Pepitone & Smith, 2011). The only way that Netflix could stay in business and regain investor confidence was to raise prices, taking the Netflix service subscription from a previous 2009 total of $5 per month, to over $10 per month in certain markets. Raising prices on this business model created significant consumer backlash and immediate defection to other brands offering similar services. To now be able to get hard copy discs delivered as well as streaming video capabilities under the service, it would now cost consumers $15.98 (Sanger, 2011). Netflix was essentially stating that the high costs of licensing the videos offered (hundreds of millions of dollars annually) and the costs of handling video returns and deliveries were justifying these sudden and significant price hikes. The major problem in this situation is that not only did the company anger its loyal customers with massive price increases, but the business did not realize the consumer loyalty

Time Managment Essay Example | Topics and Well Written Essays - 1250 words

Time Managment - Essay Example I definitely hoped that I would pick up some learning from this as I definitely did not want to waste time (that would have been truly ironic if that had happened. I was a tad bit skeptical as the seminar started, but the binder with the learning material caught my eye immediately. To allow oneself to be carried away by a multitude of conflicting concerns, to surrender to too many demands, to commit to too many projects, to want to help everyone in everything is itself to succumb to the violence of our times. Frenzy destroys our inner capacity for peace. It destroys the fruitfulness of our work, because it kills the root of inner wisdom which makes work fruitful.1 I was slightly taken aback because this seemed highly philosophical. And more importantly, what if I took on too many projects, all of them were properly scheduled and I made sure every hour of my working day counted. As the day went on I realized that this was not just about day planners and to do lists, this was about more than that. Indeed, both day planners and task lists play an important role in time management, but it was important to find out why we wanted to use time efficiently. Indeed if we were saving time what we were saving it for. We certainly could not bank time, so what was the end result there Both managing appointments and keeping to do lists were low hanging fruits. These had to be done anyway. But the purpose of this seminar was to show that there is a lot more to time management. All activities in our life could be put in one of four quadrants. They had to be either urgent and important, urgent and not important, not urgent and important, not urgent and not important. It was not about just getting things done it was getting the things which mattered done. Things which were urgent and important , are emergencies. A good time manager would avoid having too many items in this q uadrant. Plan out the important things so that they never become emergencies. Urgent and not important, these are time consuming non critical activities , they either should be ignored or atleast be moved to the back burner. A Ringing phone for example cries for your attention but you are in the middle of an important project. Let the voicemail get it. You can pick up and call all your voicemails at one time later on. Important and not urgent is the quadrant you want all your entire to do list. No emergencies and you are working only important things. Not important and not urgent. These are items which have to be tossed. They serve no purpose at all. After this we briefly went over the POSEC method. POSEC is an acronym. PRIORITIZE-Your time and define your life by goals. ORGANIZING-Things you have to accomplish regularly to be successful. (Family and Finances) STREAMLINING-Things you may not like to do, but must do. (Work and Chores) ECONOMIZING-Things you should do or may even like to do, but they're not pressingly urgent. (Past-times and Socializing) CONTRIBUTING-By paying attention to the few remaining things that make a difference. (Social Obligations)2. It was important to learn that managing was not just about managing individual minutes or hours. It was a big picture which was trying to be put together here consisting of numerous small elements. The numerous small elements in themselves meant nothing unless an overall big picture came into place. Continuing on the philosophy of time management , we made a small detour into

Leonhard Euler | An Introduction

Leonhard Euler | An Introduction Born in Basel, Switzerland on 15th April 1707, Leonhard Euler was arguably the brightest mathematician of all time. The Swiss mathematician and physicist is considered a pioneer in many fields of mathematics. He introduced a lot of the mathematical terminology and notation used today and he is considered the father of mathematical analysis where, for instance, he introduced the notation of a mathematical function, f(x). His contributions to the field of mathematics are in analytic and differential geometry, calculus, the calculus of variation, differential equations, series and the theory of numbers. In physics, although really all his contributions to mathematics apply to physics, he introduced both rigid body mechanics and analytical mechanics (Kline, 401-402). Born to Paul Euler and Margarete Bruckner, Leonhard was the first of six children. He grew up in Riehen but attended school in Basel. Although mathematics was not taught in his school his father had kindled his interest in the subject (Paul Euler had been friends with another great mathematician at the time, Johann Bernoulli) by giving him lessons at home. Euler entered university at the age of 13 at the University of Basel. Although his official courses of study were philosophy and law, Euler met with Johann Bernoulli who advised Euler and gave him help with his mathematical studies on Saturday afternoons (Stillwell, 188). Euler lived and worked mainly in Russia and Germany. First he joined the faculty at St Petersburg Academy of Sciences were he worked at first in the medical department then he was quickly promoted to a senior position in the department of mathematics through the influence of his friend Daniel Bernoulli. He also helped the Russian government on many projects including serving in the Russian navy as a medical Lieutenant. After the death of Catherine I in1740 and because of the tough conditions that ensued, Euler moved to Germany at the invitation of Prussian King, Frederick II to the Prussian Academy of Science were he stayed for the next 25 years of his life. Euler gave much service to the Academy which compensated him generously. He sent most of his works to be published there, served as a representative as well as advising the Academy on its many scientific activities. It is there that he reached the peak of his career writing about 225 memoirs on almost every topic in physics and m athematics (Varadarajan, 11). Euler returned to St. Petersburg in 1766 under the invitation of the then czarina Catherine the Great (Catherine II) to the St Petersburg Academy. During this period he lost almost all his eyesight through a series of illnesses becoming nearly totally blind by 1771. Nevertheless, his remarkable memory saw him writing about 400 memoirs during this time. It is said that he had a large slate board fixed to his desk where he wrote in large letters so that he could view dimly what was being written. He died on the 18th day of September 1783 due to cerebral hemorrhaging. It is also recorded that he was working even to his last breath; calculations of the height of flight of a hot air balloon were found on his board (Varadarajan 13). Eulers contribution to Mathematics and Physics was a lot. His ideas in analysis led to many advances in the field. Euler is famously known for the development of function expressions like the addition of terms, proving the power series expansion, the inverse tangent function and the number e: ∑ (xn/n!)= lim ((1/0!) + (x/1!) + (x2/2!) +†¦+ (xn/n!) ) =ex The power series equation in fact helped him solve the famous 1735 Basel problem: ∑ (1/n2) = lim ((1/12) + (1/22) + (1/32) + †¦+(1/n2)) = Ï€2/6 He introduced the exponential function, e, and used it plus logarithms in analytic proofs. He also defined the complex exponential function and a special case now known as the Eulers Identity: eiφ = cos φ + isin φ And eiÏ€ + 1= 0 (Eulers Identity) In fact, De Moivres formula for complex functions is derived from Eulers formula. Similarly, De Moivre is recognized for the development of calculus of variations, formulating the Euler-Lagrange equation. He was also the first to use solve problems of number theory using methods of analysis. Thus, he pioneered the theories of hyperbolic trigonometric functions, hyper geometric series, the analytic theory of continued fractions and the q-series. In fact, his work in this field led to the progress of the prime number theorem (Dunham 81). The most prominent notation introduced by Euler is f(x) to denote the function, f that maps the variable x. In fact he is the one who introduced the notion of a function to the field of mathematics. He introduced, amongst others, the letter ∑ to mean the sum, Ï€ for the proportion regarding the perimeter of a circle up to the span or the diameter, i for the imaginary unit, √(-1) and the e (2.142†¦) to represent the base of the natural logarithm. Euler also contributed to Applied Mathematics. Interestingly enough, he developed some Mathematics applications into music by which he hoped to incorporate musical theory in mathematics. This was however, not successful. This notwithstanding, Euler did solve real-world problems by applying analytical techniques. For instance, Euler incorporated the Method of Fluxions which was developed by Newton together with Leibnizs differential calculus to develop tools that eased the application of calculus in physical problems. He is remembered for improving and furthering the numerical approximation of integrals, even coming up with the Euler approximations. More broadly, he helped to describe many applications of the constants Ï€ and e, Euler numbers, Bernoulli numbers and Venn diagrams. The Euler-Bernoulli beam equation (one of the most fundamental equations in engineering) is just one of the contributions of the mathematician to physics. He used his analytical skills in classical mechanics and used the same methods in solving celestial problems. He determined the orbits of celestial bodies and calculated the parallax of the sun. He differed with Newton (then the authority in physics) on his corpuscular theory of light. He supported the wave theory of light proposed by Hugens. Eulers contributions to graph theory are at the heart of the field of topology. He is famously known to have solved the Seven Bridges of Konigsberg problem, the solution of which is considered the first theorem of planar graph theory. He introduced the formula V-E+F=2 It is a mathematical formula relating vertices, edges and faces of a planar graph or polyhedron. The constant in the above formula in now called the Euler characteristic. Euler is also recognized for the use of closed curves in the provision of explanation concerning reasoning which is of syllogistic nature. Afterwards the illustration or diagrams were referred to as the Euler diagrams. The Number Theory is perhaps the most difficult branch of mathematics. Euler used ideas in analysis linking them with the nature of prime numbers to provide evidence that the total of all the reciprocals of prime numbers diverges. He also discovered the link between the primes Riemann zeta function, what is now called the Euler product formula for the Riemann zeta function. Euler made great strides in the Lagrange four-square theorem while proving Fermats theorem on the sum of two squares, Fermats Identities and Newtons identities. Number theory consists of several divisions which include the following: Algebraic Number Theory, Combinational Number theory, Analytic Number Theory, Transcendental number theory, Geometric number theory and lastly we have the Computational Number Theory. For his numerous contributions to academia, Euler won numerous awards. He won the Paris Academy Prize twelve times over the course of his career. He was elected as a foreign member, in 1755, of the Royal Swedish Academy of Sciences while his image has been featured on many Russian, Swiss and German postage stamps. Above all, he was respected greatly amongst his academic peers demonstrated by a statement made by the great French mathematician, Laplace to his students to read Euler since he was the master of them all (Dunham xiii). Though not all of the proofs of Euler are satisfactory in regard to the current standards or principles used in mathematics, the ideas created by him are of great importance. They have set a path to the current mathematical advancements. To conclude, we can therefore say that Euler is a very significant person in the development and advancement of Mathematics. His work has contributed a lot to mathematics up to the current period. References Dunham, William. Euler: The Master of Us All. Dolciani Mathemathical Expositions Vol. 22. MAAA, 1999. Kline, Morris.

Literacy Essay -- Education Learning Papers

Literacy Why is literacy of such interest to postsecondary teachers of writing? If "literacy," as it might be defined by someone outside the field of English studies, is "the ability to read and write," then why are we interested in it when our own students presumably acquired this ability in the distant past, about the time they learned to tie bows in shoelaces? That we are interested in literacy, I take it, is obvious from the proliferation of books with the word in their titles, of conferences on topics in literacy (the Modern Language Association has now held two), and of review essays such as this one, commissioned by the editors of a journal that purports to deal in issues relevant to "composition theory" and "advanced composition" at the college level. Defining Literacy I might answer my opening question by redefining "literacy" from within English studies in such a way as to make it more complex and problematic, and thus to question the presumption that college students have already acquired it. Indeed, in these proliferating discussions of literacy, its simple definition as the ability to read and write is usually rejected at the outset. But in attempting to go beyond the simple definition, scholars begin to diverge. Consider, for example, the variety of essays collected under the title, The Right to Literacy (1990), a title which implies a unitary conception of literacy and a contest only over who possesses the desired object. In this volume, Andrea A. Lunsford, Helene Moglen, and James Slevin collect twenty-nine papers from the 1988 MLA "Right to Literacy" conference. Most of the essays, therefore, are short; and ranging through them, one gets a sense of the heterogeneous mixture of topics that accrue for Engli... ...Discourse Community."

Is Hip-Hop Culture Harming Our Youth?

Is Hip-Hop Culture Harming Our Youth? Hip-hop culture is everywhere. The culture, which encompasses rapping, deejaying, break-dancing and graffiti-writing, has become so popular that it has entered mainstream fashion and modern language. It doesn't stop there. The culture permeates everything from TV commercials to toys to video games. Currently, there is even a hip-hop exhibit at the Brooklyn Museum of Art. You name it, and hip hop is there representing. However, hip hop's most potent form is its rap music–embraced by urban Blacks and suburban Whites alike.It is raw self-expression that sometimes features profane lyrics, misogyny and violence. The music, along with rap videos that often present a disturbing mix of rap, hip-hop dance styles, fashion and language, leave many people asking: â€Å"Is hip-hop culture harming our youth? â€Å". â€Å"The hip-hop culture is just like electricity,† civil rights leader the Rev. Al Sharpton told JET. â€Å"It can be used nega tively or positively. The same electric current that lights up your house can also electrocute you.It is the misuse of hip-hop culture to attack our women and promote violence. We must encourage the proper use of hip-hop culture. We are all influenced by the hip-hop generation. † Sharpton, who recently hosted a special summit on social responsibility in the hip-hop industry, labeled gangsta rappers â€Å"well-paid slaves. † Advertisement â€Å"Don't let some record executive tell you that cursing out your mama is in style. Anytime you perpetuate a slave mentality that desecrates women and that desecrates our race in the name of a record†¦. I consider you a well-paid slave. Sharpton labeled the fashion of these rappers–loose-fitting pants and sneakers without shoelaces–prison clothes. Sharpton was joined at the summit by some of the industry's superstars, including Master P, Sean â€Å"Puffy† Combs, Chuck D and RZA. No Limit Records' CEO-rapper Master P apologetically admitted that some of his lyrics might be offensive to women. â€Å"Everything that came from me like that came out of ignorance. I hope to edit myself in the future,† he reportedly said during the event. However, he asserted, â€Å"I don't believe any form of entertainment is harming our youth.It is up to parents to raise their own children and teach them. Blaming entertainment is a scapegoat. † Dr. C. DeLores Tucker, chair of the National Political Congress of Black Women, Inc. , who has been a strong critic of hip-hop culture for more than a decade, continues to cite its reported negative influence over our youth. â€Å"The glorification of pornography, wanton disregard for civil authority, misogynistic disrespect for women and a penchant for violence are the unintended impact of hip-hop culture on today's youth,† the activist revealed. I say unintended, because hip hop †¦ was intended to celebrate the revival of the age-old rhym ed recitations of life's problems and aspirations set to music. † Unfortunately, somewhere along the way, some unscrupulous elements hijacked this influential conduit to our youth and loaded it with the evil and debasing, hate-driven messages in the lyrics we now know as gangsta rap. Hence the artistry of the rappers in the streets is used by the gangstas in the suites to spread cultural garbage among our youth. Hip-hop music mogul Russell Simmons, who dubs himself the â€Å"grandfather of hip hop,† says the culture has been helpful in allowing others to understand Blacks' inner-city plight. â€Å"It is not going to go away. I will stand by the door to keep it from being censored. It is easy to try to put a lid on what you don't like. But the real test, if you are freedom-loving people, is to protect even that which we don't like from the censorship by the government,† he explained. He points out the positive contributions from the hip-hop culture. The slam poetr y settings evolved out of the hip-hop community. Some of it does not have any curse words. Young folks have found a way to express themselves that was really inspired by rap. Kids are writing. They are thinking; brilliant thoughts are coming out in this creative poetry. † Concludes Simmons, â€Å"The hip-hop culture will evolve in ways that will be known as a significant art. The rap artists are not the poets that they are yet to become, but they are indeed poets. â€Å"
