Living in a Frictionless World Essay Example

Living in a Frictionless World Paper Problems that could occur in a frictionless world: One of the most known problems would be that everything will slip; there will be no friction helping the object to stay in place. One example is when you are walking, you will slip a lot because there is no friction between the ground and your foot (or what you are wearing on your feet). Another example Is that you cannot hold anything; everything you try to hold will slip off your hand. Another very dangerous Issue would be when you are driving a vehicle; the vehicle will never stop moving unless It crashed Into something. There will no longer be any alarm resistance If friction does not exist on Earth. Thus, any meteorite that Is falling towards Earths surface will have no alarm resistance to create friction which generates heat. Henceforth, the meteorite will not lose any volume. This will make life a lot more dangerous when a meteorite Is crashing onto Earth. Another concern will be that you cannot digest any of your food; this Is because it requires friction for your body to digest food. Also, whatever you digest in your body will immediately exit your body because there is no friction to hold it in your body. Thus, human will not be able to survive for too long without friction. 2. Steps to help humankind to survive and function: As stated above, human will not be able to survive for so long without friction due to he fact that their body cannot digest food or store any ingested solid or liquid.

Or what human could do is build restaurant in that area where there is friction for people to eat. This way, if the people eat there, their food could be digested. They should stay in that area for a couple of hours (long enough for their food to be digested).

Pros and Cons of Hydrogen Fuel-Cell Vehicles

Pros and Cons of Hydrogen Fuel-Cell Vehicles The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. Two main hurdles stand in the way of mass production and widespread consumer adoption of hydrogen â€Å"fuel-cell† vehicles: the still high cost of producing fuel cells; and the lack of a hydrogen refueling network. The High Cost of Building Hydrogen Fuel-Cell Vehicles Reining in manufacturing costs of fuel-cell vehicles is the first major issue the automakers are addressing. Several had  fuel-cell prototype vehicles on the road, sometimes even leasing them to the public, but they were spending upwards of $1 million to produce each one due to the advanced technology involved and low production runs. Toyota reduced its costs per fuel-cell vehicle and as of 2015 sells its Mirai model for close to $60,000 in the United States. The Honda FCX Clarity is available only in southern California. Other manufacturers have been investing in developing mass-market models as well.   Still Too Few Places to Refuel Another problem is the lack of hydrogen refueling stations. Major oil companies have been loathe to set up hydrogen tanks at existing gas stations for many reasons, ranging from safety to cost to lack of demand. But obviously the oil companies are also trying to keep customers interested in their highly profitable bread-and-butter product: gasoline. A more likely scenario is what is emerging in California, where a few dozen  independent hydrogen fuel stations are located around the state as part of a network created by the nonprofit California Fuel Cell Partnership, a consortium of automakers, state and federal agencies, and other parties interested in furthering hydrogen fuel-cell technologies. The Benefits of Hydrogen Over Fossil Fuels The benefits of ditching fossil fuels for hydrogen are many, of course. Burning fossil fuels like coal, natural gas and oil to heat and cool our buildings and run our vehicles takes a heavy toll on the environment, contributing significantly to both local problems such as elevated particulate levels and global ones such as a warming climate. The only by-product of running a hydrogen-powered fuel cell is oxygen and a trickle of water, neither of which will cause any harm to human health or the environment. Hydrogen Is Still Closely Tied to Fossil Fuels But right now, a large percentage of the hydrogen available in the United States is either extracted from fossil fuels or made using electrolytic processes powered by fossil fuels, thus negating any real emissions savings or reduction in fossil-fuel usage. Only if renewable energy sources- solar, wind, and others- can be harnessed to provide the energy to process hydrogen fuel can the dream of a truly clean hydrogen fuel be realized. Renewable Energy the Key to Clean Hydrogen Fuel Stanford University researchers in 2005 assessed the environmental effects of three different hydrogen sources: coal, natural gas, and water electrolysis powered by wind. They concluded that we would lower greenhouse gas emissions more by driving gasoline/electric hybrid cars than by driving fuel-cell cars run on hydrogen from coal. Hydrogen made using natural gas would fare a little bit better in terms of pollution output, while making it from wind power would be a slam-dunk for the environment.

Human Growth Hormone Replacement Therapy and Aging Essay

Human Growth Hormone Replacement Therapy and Aging - Essay Example in 2001. The scientists state that while the reduction of concentration of somatotropin during aging is documented, there were several problems with previous researches as they did not exclude the various gonadotropic hormones that were also reduced with old age. The study was performed on two groups, a young group, consisting of 8 men and 8 women, and an aging group consisting of 11 women and 10 men. All the subjects had similar body mass indexes and blood samples were taken from each of the test subjects every 10 minutes for 24 hours. The results from the research showed a marked decrease of 32-56% of growth hormone concentration, each according to its sex. 81% of the young group secreted the highest amount of growth hormone during the night period, while 62% of the aging group secreted most of the growth hormone during the day period. The researchers reached the conclusion that there is a decrease in secretion of growth hormone as age increases for both sexes. The reduced concentr ation of growth hormone was, in turn seen as a lack of growth hormone releasing hormone. (Russel-Aulet et al.) Another research focuses on the problem of sarcopenia, which represents a syndrome that manifests itself as a decrease in skeletal muscle mass, as well as in muscle work output. As the natural process of aging involves degradation of skeletal proteins, sarcopenia is expected to appear in most of the elderly, but this condition can be aggravated by the lack of exercise, leading to more frequent physical injuries such as hip fractures. Aware of the low concentration of several hormones that affect protein anabolism in old age, amongst them the growth hormone, the scientists researched the coupled human growth hormone replacement therapy with resistance exercise, which is known to reduce the effects of sarcopenia, in people aged 60 and over. Although the research can be viewed as retrospective, as it presents the various experiments, as well as the results, performed by other researchers, a case-control trial was described that was performed by the authors of the paper. The study invol ved men from 62-75 years of age which were involved in a 16 week exercise program, consisting of modest to high-intensity training in the form of weight lifting exercises with a small repetition. It encompassed muscles from both the upper and lower extremities. One group was given a dose of 12-24 g/kg/d of growth hormone, while the other, control, group performed the same exercises, but was not given anything. The result from their research, as well as results from other researches, led the scientists to conclude that there is not much difference in muscle mass and strength between the control group and the group that received somatotropin. An increase in muscle mass was present, however, but not focused on the skeletal muscles. Furthermore, the scientists concluded that there were significant side effects from the use of somatotropin replacement therapy in aging people, further criticizing the use of somatotropin as a means to prevent sarcopenia. (Zachwieja, Yarasheski). Sarcopenia is but one of the many physiological

MCI WorldCom Essay Example for Free

MCI WorldCom Essay As noted above, Latin America is and has been ahead of many countries with emerging economies in the development of its telecommunications sectors and the attraction of private investment. Similarly, it has been substantially advanced in its promulgation of rules and regulations, changing as required to keep up with constant change in technology and services. All of the above drives or suppresses competition and growth depending on how the change is effected and how effective enforcement is executed. In Mexico, we have seen investment moratoria declared by MCI WorldCom and ATT based on alleged failure of the Government to enforce the telecommunications regulations against TELMEX, which most affect the economics of service-provision by the competitors. While resolution has commenced of these issues in Mexico, full resolution is not yet a reality, and the sector has suffered a slow-down in investment at a time when investment should have been the most robust in Mexicos history. On the other hand, one sees in Mexico, a reversal of the cross subsidies which previously characterized the service of TELMEX. For example, before privatization, TELMEXs local exchange service failed to cover one third of its costs and was permanently subsidized by TELMEXs dramatically high international tariffs. That has reversed, forced, in part, by the requirements of its Concession and the introduction of competition in long distance and international service. As new international operators can compete on price, without regard to local exchange service, if the incumbent does not lower international prices and remain competitive, it will lose a large portion of its revenue and its best and most lucrative customers. In fact, some of the most vigorous of the complaints of TELMEXs interconnection and access charge practices demonstrated a policy of avoidance of competition in this lucrative market. Currently, ITU reports show dramatically higher local exchange charges than those, which characterized the pre-privatization company. Indeed, TELMEX monthly recurring charge is on par with other countries of Latin America which have rebalanced their tariffs to eliminate the cross subsidies. Thus, it is significantly higher than monthly recurring residential charges of companies in other countries that have not been obligated to rebalance. The latter means that those countries remain largely without formal or effective competition. This is because competition forces rebalancing of tariffs in order for the incumbent to maintain market share in the price-competitive and lucrative markets like long distance, international and commercial. Similarly, Argentina and Peru have monthly recurring charges, which reflect a rebalancing of tariffs and elimination of much of the cross-subsidies that previously characterized the companys finances. This means necessarily, a higher monthly recurring residential charge than countries such as Paraguay, Surinam and others that have not yet eliminated their cross subsidies (again typically revealing a lack of competition which threatens the market share of lucrative and over-charged markets). As noted earlier, the law and the vigorous competition in Chile contributed to the elimination of cross subsidies and the balancing of tariffs with cost of providing the service. Thus, like Argentina, Peru and Mexico, Chile had monthly recurring residential charges, which reflected its cost of providing the service, and operators competed vigorously in long distance and international pricing for market share. At the end of 1999, however, the Government forced a lowering of monthly recurring charges, which substantially impacted the revenue balance of local exchange carriers. That is, with long distance and international tariffs subject to severe competition and thus as marginally low as possible, the monthly recurring charge is one of the few revenue sources available to generate margin. While it cannot create wide margins as monopoly international services once did due to the economy of the market of residential users, it at least covered its costs and generated profit in a rebalanced tariffing environment. Now Chilean local exchange carriers are saying that the new rules no longer allow that. Thus, they have declared a moratorium on the construction of local exchange infrastructure. Perhaps by the time of the PTC conference, we shall have a resolution of the dispute. What all of the above, and current marketing of services in other countries, like the U. S. , cause us to think about is how networks will be paid for in the future. In a technological environment where long distance is virtually the same as local exchange service (eg. ATT advertises its one service which encompasses the entire of the U. S. , local and long distance; Venezuela has reduced its domestic long distance to two regions, all else within them is local exchange; Sprint sells its ten cent minute anywhere in the country, etc); wire line virtually the same as wireless (Ugandas second national operator uses exclusively a GSM cellular network with software distinctions for price-capped services; Canada and U. S. move toward wireless local loop being interchangeable with cellular and fixed line telephony); data equals voice services (GPRS and UMTS provide telephony services with internet access, interactive email and other mixed services features), etc. Thus, technological convergence; global seamless mergers of services and service operators and new means of delivery, like the INTERNET, point toward different measures of financing infrastructure build-out. For example, whereas operators used long distance and international revenues predominantly in the past as a primary revenue stream, which supported financing of build-out, those streams have shrunk substantially in a competitive environment. The same is true for international settlements. Now, as we are seeing in Chile, the same could be true in the future for the monthly recurring charge on local exchange service. Prepaid services and cellular or other wireless substitutes for local exchange service, already threaten this revenue stream.

Overcoming the Giant :: Art Arts Films Film Movies Essays

Overcoming the Giant "And he slung it and struck the Philistine in his forehead . . . and he fell on his face to the earth" (1 Samuel 17:49b). The Biblical account of David and Goliath is the most famous incident of the underdog defeating the giant. Since this event, history has seen giant after giant overcome by a seemingly insignificant underdog. Alexander the Great, before he was given his title, defeated a supposedly unconquerable Persian army, led by King Xerxes. In the 1960s, Joe Namath, quarterback of the New York Jets, predicted and delivered a shocking victory over the heavily favored Baltimore Colts. Even in fairy tales, the theme lives on in "Jack and the Beanstalk." And, today, in the heart of San Jose, another David-and-Goliath scenario has arisen between the Camera Theaters and the mainstream Cinemas. But this time, the hurdle is daunting. Can the Camera Theaters overcome this giant, or are the challenges too numerous and too great? There is, of course, one main obstacle for the Camera Theaters to overcome if they are to survive: they must draw more teens. Why are teenagers so important to the movie industry? When it comes to making money in the movie industry, it is statistically proven that the largest profit contributors are 16-20 year old males. While the art films in downtown San Jose draw educated, sophisticated 35 year-old audiences, they have not drawn the young moviegoers. This, in a nutshell, is the challenge the Camera Theaters must break in order to survive the tightening grip of the merciless cinemas. However, we must recognize the multiple pieces that makeup the nutshell before we can crack it. To determine what the Camera Theaters need to do in order to overcome the lack of teenagers it draws, the writer took an unofficial poll that has laid out the biggest reasons for the lack of interest among teenagers. The poll taken showed that 60% of Prospect High School students have never been to either of the Camera Theaters, thus confirming the hypothesis that the theaters need to draw teens through their doors. But the poll went further: it also showed that 40% of students had never even heard of the Camera Theaters. Therein lies problem number one in drawing teens: lack of publicity. For the Camera Theaters to survive they must find a way to gain publicity. In 1993, when it seemed like the Cameras were going to close, twelve art film theater owners wrote letters of support and thirteen newspaper editorials were written on the situation.
