America Must Regulate Nanotechnology Essay -- Technology Physics Mecha

America Must Regulate Nanotechnology Definition of Nanotechnology Nanotechnology involves the â€Å"art of purposefully manipulating materials on at atomic scale or molecular scale†[1] (also referred to as â€Å"nanoscale†), as compared to processes governed by the laws of physics that carry out naturally occurring actions, such as chemical reactions and changes in state. At the nanoscale level, the laws of quantum mechanics take over, pushing aside what most are familiar with via Newtonian mechanics. Because of the fundamental shift in how work is done, nanotechnology has the potential to affect and change everything in existence. Future Implications of Nanotechnology Nanotechnology will affect everything, and likely change everything to significant degrees. The future implications of nanotechnology exist along all frontiers of science, culture, commerce, economy, business, law, ethics, medicine/health, religion, and life. The end result of these changes will, however, either advance human civilization several orders of magnitude forward and thus achieve â€Å"utopia† if properly managed and regulated, or bring an end to human civilization if not properly controlled, studied, and managed, akin to â€Å"Pandora’s Box† of ancient Greek mythology, but several orders of magnitude worse! Some significant implications as a result of nanotechnology include[2]:  · Nearly free consumer products  · PC's billions of times faster then today  · People live longer with virtual ends to illness and aging  · No more pollution and automatic cleanup of existing pollution . End of famine and starvation  · Superior education for every child on Earth These implications could become reality in the near ... .../view/library/aliens/article/70558.html [12] â€Å"Library-Technology – Nanoprobes†, StarTrek.com, http://www.startrek.com/startrek/view/library/technology/article/3963.html [13] National Nanotechnology Infrastructure Network, http://www.nnin.org/ [14] National Nanotechnology Initiative, http://www.nano.gov [15] Center for Responsible Nanotechnology, http://www.crnano.org [16] â€Å"Everything or Nothing Overview†, http://www.commanderbond.net/Public/Stories/2279-1.shtml [17] â€Å"Nanotechnology Now – Ethics of Nanotechnology†, http://nanotech-now.com/ethics-of-nanotechnology.htm [18] Rob Fixmer, "The Soul of the Next New Machine: Humans", New York Times on the Web (November 5, 1999), http://cseserv.engr.scu.edu/NQuinn/ENGR019_301Winter2004/HWBCCCU.htm [19] â€Å"Telecommunications Act of 1996†, Federal Communications Commission, http://www.fcc.gov/telecom.html

Comparing Sir Walter Raleighs The Nymphs Reply to the Shepherd to Chr

Comparing Sir Walter Raleigh's "The Nymph's Reply to the Shepherd" to Christopher Marlowe's "The Passionate Shepherd to His Love"Â   Sir Walter Raleigh wrote "The Nymph's Reply to the Shepherd" in 1600 to respond to Christopher Marlowe's "The Passionate Shepherd to His Love" written in 1599. In " The Passionate Shepherd to His Love", the Shepherd used double-entendres and hidden sexual images in an attempt to trick the Nymph into performing sexual intercourse with him. The Shepherd attempted to convince the Nymph that he would bestow her the various presents and pleasures that he described, but in reality his gifts only comprised of sexual meanings. However, the Nymph was exceedingly intelligent and conscious of the Shepherd's hidden seductions. She was so smart, that she hastily rejected the Shepherd's proposal by using the exact words that the Shepherd used in his request. The Shepherd in Marlowe's poem used disguised sexual images in hope that the Nymph would be attracted to him. The Shepherd first offered the Nymph "...valleys, groves, hills, and fields, / woods, or steepy mountain yields" ( ). He hopes that the Nymph would interpret the images as places he would like to take her, but in actuality the Shepherd was describing to the Nymph the various parts and curves of her body which he would like to explore. The Nymph replies to his offer by stating "The flowers do fade, and wanton fields, / to wayward winter reckoning yields " ( ). Which means that things change and though the Shepherd has a sexually unrestrained body, that through time he will become headstrong and unwilling to continue the sexual pleasures. As the poem continues, the Shepherd offers the Nymph "a belt of straw and ivy buds" ( ). The belt and ... ... have moved you, then come live with me so that we may continue making these "pleasures". The Nymph replied with "If truth in every shepherd's tongue/ these pretty pleasures might me move" (2-3). She would be moved by what the Shepherd said if he wanted more from her than just a sexual relationship. Through reading the works by Marlowe and Raleigh it's determined that the shepherd had only sexual feelings for the Nymph. The poems showed no acts of love, only sexual desires that the Shepherd was feeling and a strong sense of rejection from the Nymph. The Nymph did an extraordinary job of standing up for herself. The Shepherd failed in his plan to trick the Nymph and ended up looking like a jackass. Works Cited: Marlowe, Christopher. "The Passionate Shepherd to His Love."

Football player Essay

The amount of extra oxygen required by muscle tissue during recovery from vigorous exercise. The extra oxygen gets rid of the lactic acid in your muscles after exercise. Difference between Aerobic and Anaerobic Training The main difference between aerobic and anaerobic training is that one uses oxygen whilst the other uses lactic acid. Aerobic training uses the oxygen in your muscles to produce the energy. To improve the amount of time which you are able to train at aerobic level you can do aerobic exercises, these are normally done at a moderate pace which your body can cope with. On the other hand anaerobic training is when the oxygen in your muscles run out so you rely on lactic acid to give you energy. The energy released does not last for long however is very powerful. The lactic acid causes your muscles to start aching though and can result in vomiting. Anaerobic respiration occurs when you work your body flat out and use all the energy available. Effect of Lactic Acid on the muscles Lactic acid is a waste product that is produced by your muscles when exercising. When the body has no oxygen left in the muscles it has to revert to anaerobic respiration which uses lactic acid to form energy. The lactic acid though makes your muscles ache and tire so is not very efficient. Difference in composition between inhaled and exhaled air The air that we breathe in and the air which we breathe out, have different compositions. The main difference is that in exhaled air there is more carbon dioxide compared with inhaled air where there is more oxygen. However in both types nitrogen is the highest percentage. Here are the components of inhaled air, 79% nitrogen, 21% oxygen, a little water vapour,0. 04% carbon dioxide whereas exhaled air contains79% nitrogen17% oxygen3% carbon dioxide, a little water vapour. As you can see from the two lists they are basically the same however there is more carbon dioxide and less oxygen in exhaled air. Effects of exercise on breathing and heart rate A lot of exercise can also affect your respiratory and circulatory system, because your heart gets bigger due to aerobic training, it is now a better pump so more blood can be circulated around your body per beat than before. This also means that your resting heart rate decreases. A sign of good health is whether you have a low heart rate. The average is 70BPM (beats per minute), if you are unhealthy then your heart will have to work harder to pump blood all around your body which makes heart attacks more likely. Effects of Training In this section I will explain the effects on the body that I will expect to see when my Personal Exercise Plan has been completed over the 6 weeks. After completing my PEP my muscles should change in size and strength due to the exercises I have chosen. The muscles should grow larger with the exercise because the muscle fibres in the muscle will get fatter. Muscles are built from fibres which are either fast twitch or slow twitch. The strength of the muscle should also improve with exercise, by doing exercises with heavy weights and few reps the muscle strength will be increased. If I changed the exercise to many reps with a light weight then my muscles will gain more endurance. But as I am a goalkeeper then I will not concentrate as much on the endurance training. Changes to Vital Capacity and Tidal Volume in the lungs From completing my 6 week training routine I should be able to see changes in my Vital Capacity and Tidal Volume. VC= Your Vital Capacity is the maximum amount of air that can be forcibly exhaled from your lungs. TV= Your Tidal Volume is all the air inhaled and exhaled in a minute. With training the respiratory system I will expect to see an increase in both of these factors. These increases are down to the lungs as training on my respiratory system will make them bigger so I will be able to inhale and exhale more air per breath. SV = Stroke Volume is the volume of blood pumped out of the heart during one contraction. Due to exercise this should increase as your heart will be stronger, therefore it will be able to pump a larger volume of blood around the body. CO = Cardiac Output is the amount of blood which is pumped from your heart each minute. This can be worked out by multiplying your stroke volume with your heart rate. This should also increase with exercise, by the same reasons as your stroke volume increases, as your heart is stronger. Recovery rate = Your recovery rate is the amount of time it takes you to fully recover after exercise. The fitter you are the shorter your recovery rate is. As I am a goalkeeper I will not be concentrating on this too much as it is not that important, although for an outfield player it is very important. SPORT Principles of training The main principles of training are shown in the acronym SPORT, by using these in my PEP I should end up with a successful training programme. The different sections are: S= Specificity Specificity means that I will train specific muscles used in my sport. This could include exercises and drills that relate to moves and skills I need in football as a goalkeeper. I will specify flexibility and muscular strength as these are the two components most vital for my sport. P= Progression Progression is when you gradually increase the amount or intensity of your exercise. This will improve your muscles as you are increasing the amount of work they do. An example of progression is starting week 1 with a 2 mile run once a week then progressing to a 3 mile run in week 2. O= Overload Fitness can only be improved by doing more than you usually do. This is called overloading. You must be careful though as if you do too much training you will end up injuring yourself. An example is doubling the distance of your runs or doubling the weight of your weights. R= Reversibility Reversibility occurs when you do not train . As your muscles are not being worked they will begin to weaken. All the improvements you have made from training will be reversed. For example if a sportsman becomes injured and is unable to train they will lose their work. So that reversibility does not affect me I will have 3 training sessions per week. T= Tedium Tedium is when you become bored with your training, this is because your training plan does not have much variety and you end up doing the same exercises. To avoid tedium I will include a variety of exercises so my PEP is not boring. FITT Principles When using overload I can use the FITT principles of training which are: F= Frequency Frequency is to do with how often I should train. I will include 3 training sessions a week in my personal exercise plan; this is a sufficient amount as I am not a professional sportsman who will probably train around 5 times a week. By doing 3 sessions a week I will also minimise the chance of reversibility as I will not have a large gap of time when I am not exercising. To make sure that my PEP is well set out I will not have to exercise in 2 consecutive days, for example I will train on Monday, Wednesday and Friday. I= Intensity Intensity is based on how hard you push yourself whilst doing your training. It is measured by MHR (Maximum Heart Rate) for example a 3 mile run at 70% MHR. As I progress through the training programme the intensity of my exercises will increase. For the first week I may start working at 65% MHR which is not too hard however by the 6th week I will be working at 80% MHR which will be working my body very hard. T= Time Time is the length I will train for during each session of my PEP. It can vary from sprinting for 10 seconds to jogging for an hour. Time will be used in my exercise plan as I will increase the length of time spent on each exercise as I progress through the 6 weeks to show progression. T= Type There are different types of training, continuous training, fartlek training, circuit training, aerobic training and interval training, I will mainly use circuit, interval and aerobic training as these will be of most help to me. Fartlek and continuous training both contain a lot of running, which will not be useful to me as I play in goal. However I will use aerobic training as it will help me with my flexibility and agility, whilst interval and circuit training can use many exercises which I can choose myself. This will also lessen the chance of tedium occurring.

Global Impact of E-Commerce on Society Essay

Explanation positive effects 1. Convenience : e-commerce is very convenient for customer ,because it accepts different type of credit and debit cards and as many other forms of payment as possible . customer don’t need to go anywhere for payment ,customer can carry as many items in stock as possible to avoid backorder ,it is often convenience because the order goes hand –in –hand with in timelines to customer. 2.

Humans & ability Essay

Humans’ most important ability is our ability to communicate through spoken language. The ability of humans to speak makes us stand out in the animal kingdom, according to many philosophers and scientists. It is just natural for humans to desire to know how we developed the ability of using language in communicating. This paper focuses on how the human language evolved. Through the comparative studies of the apes with the human language, it provided information to humans when the necessity for the language structure was developed. INTRODUCTION Study of Primates Communication Abilities. Since the ‘homo sapiens’ have been considered as the human’s cousin, the language of the apes have been studied. Some believes that the human language evolved earlier than them. The American Sign Language or ASL has been taught to a number of apes. Different approaches were also used from 1970s for some species of apes to be trained and taught disciplines of communication. Comparison of the Primate and Human Communication Abilities. Human children’s development of their language was compared to the studies made on different forms of primates. It was evident on human children that their development comes slowly as they grow older. Children in the earliest age start with a single word utterance. At fifteen months old of a child, utterance of two words comes easier. Protosyntatic structures in the language development of children come next with longer word utterances. At this stage, noun phrases were observed in the language structure too. This kind of language development on children is comparatively the same with many primates studied from 1970s to present. CONCLUSION The ability of primates to communicate with protolanguage may be a sign that apes can actually understand, learn, and communicate. However, in many instances where primates were trained and disciplined, it is also important to consider that none of the subjects were able to be taught to verbally speak. Moreover, primate language studies have never showed any language exhibitions from the primates in the wild. The protolanguage development on the human children may be a similarity on both but the primates lack the gestural complex in humans. Therefore, this comparison shows that the humans have the natural linguistic ability and the primates do not. WORKS CITED William O’Grady, et al. (1997).

Genders at work - Essay Example t like the article of tools for resolving conflicts, Ury, offers simple and elegant ways of creating agreement in difficult situations from the conflicts of the family to worldwide wars (Goodwin & Griffith, 2007). The story of Ury guides us on how to resolve conflicts and wars. According to the article, sharing stories is regarded as an effective instrument for social justice and peace. This relates to a William piece of work where he negotiated peace in worldwide conflicts and choosing various stories that will make a difference globally. The article focusses on the negotiation psychology as a principled negotiation that is important in finding acceptable solutions by finding the needs that are fixed and flexible to negotiators. Just like in the Ury’s speech the tools effectively for conflict resolution include separating people from problems, focusing on interest not positions, working together in creating opinions that will satisfy the two parties, and negotiating successfully with those who are more powerful, refusing to play by the rules or resorting to dirty tricks (Goodwin & Griffith,

Week One Discussion Questions (Mgt-437) Project Management - Essay Example A project’s focus looks at the strategic tilt of the business as the project gives the indication whether or not the success will be achieved for the different business entities and how the same will shape up the future realms of the business in the long run. 2. What is a project life cycle? How do project life cycles differ among organizations? To what degree does the structure of the project life cycle used by the organization affect the project manager’s job? Explain your answer. A project life cycle is a series of steps that are taken in order to reach the end goal within a project itself. It is important that a project life cycle is apparently drawn in order to assist the project team members in understanding the work domains. Project life cycles differ amongst organizations because they depend upon the nature of the project work, their deadline requirements that need to be taken care of and the stakeholders who will be directly or indirectly affected by the project in essence. The project manager’s job is seriously affected by the project life cycle because it makes him wait for certain activities to end before he could align the other project deliverables. The need for understanding the time glitches and work requirements is essential for a project manager in order to deliver value. A project stakeholder is a person who is directly or indirectly affected by the project’s results. Some examples of project stakeholders include the people who have invested heavily within the project’s domains as well as those who remain within the background but are linked with the project on a very constant basis. The stakeholders of a project are also comprised of the people who will be affected by the outcome of a project in the long run. When stakeholders are not identified and addressed early on in the project, the projects get affected by such incidents in a very
