Rap music has a long history starting back to the days of slavery and has come a long way since then bridging gaps between all genres of music including jazz, blues, and basic drum beats. When hip hop first came about its message was simple. It was groups of black men who described the life they were living in the ghettos all over the world.

In the video, Salt N Pepper show men the same way women have always been portrayed in male videos. They have very muscular men who are wearing nothing but bathing trunks. The goal here is to place men in the same objectifying roles that women ha ve been placed in.

Supply Chain Management Organizations always seek to have an efficient system of running operations. If operations are running smoothly, an organization can cut costs and increase its profitability. Since there are so many organizations offering the same goods or services, competition becomes very fierce. For an organization that wants to stay ahead of competition, efficiency in the supply chain is no longer an option but a priority.

By the time Gate Gourmet has the actual number, there is too little time left to order supplies, prepare and deliver food and drinks in their right quantity. Air travel is usually affected in a very large scale by political environment, natural disasters or even a mechanical error. As such, no one can guarantee that a certain flight will travel from one point to another. This means that a huge number of passengers expected in an airport may not turn up. This poses a problem in the supply chain since some goods must be ordered in advance. Since most of them are perishable, if there are no customers it becomes a loss to both Gate Gourmet and the airline. During the volcanic ash that occurred in Iceland in 2010, about 500 flights were cancelled. Such a large number of passengers cause large scale changes in the supply chain. Suppliers of food to the company will definitely be affected. Since some are on contract, Gate Gourmet continues to pay even when its output has been reduced. This was also the case of 9/11 attack that led to lots of flights being cancelled. In this case some airlines did not allow food and cutlery in the planes any longer for security concerns.

Non-Cognitivists vs. Moral Realism Free Essays

Cognitive sentences are those that are dependent to facts and readily have or consist of truth values, such as true and false. Non-Cognitive Sentences constitutes statements which are independent of facts and are cannot be assumed to have a truth value. In this regards, statements such as â€Å"Girelle is stands about five feet and five inches tall† and â€Å"the vase is red† are statements which falls under the Cognitive division. We will write a custom essay sample on Non-Cognitivists vs. Moral Realism or any similar topic only for you Order Now While statements like â€Å"keep quiet† and â€Å"you must not lie† corresponds to Non-cognitive statements.(Marturano 2006, 1) According to the Stanford Encyclopedia of philosophy, Non-cognitive holds that moral properties otherwise known as moral facts do not exist. This means that moral statements are statements that can neither be true or false or simply these statements do not contain any truth condition. Moral sentiments are merely â€Å"approval or disapproval† expressions more akin to wishes and aspirations that are seldom associated with emotions than to cognitive â€Å"state of mind† such as beliefs or ideas. Moral Realism on the other hand holds that moral statements were actually reports of factual actions or ideas that are always true or real or existing. ( Sayre-McCord 2005, 1) Non-cognitivist argues that moral statements have no truth conditions in such case that their predicate was merely moral utterances or sentiments that neither have truth or falsity. It does not tell anything about its subject that could prove its truthfulness. In a sense, moral sentiments are meaningless and remain to be mere expressions. They further argue that moral statements were emotive, prescriptive and motivational that cannot be classified as either true or false (Ayer 1936, 28-55) .Non-moral statements on the other hand can express beliefs and ideas that can be evaluated as either true or false (Blackburn 1984, 12-25). Thus the Non-Cognitivist holds that since moral claims are non-cognitive statements, they do not contain any descriptive sentence and are therefore not describing anything at all which means that they do not contain factual statements and are not asserting anything.(Railton 1986, 4-6) The Non-cognitivist believes that normative claims are not valid of any logic since they cannot be true or false. According to Ayer, as quoted in the Internet Encyclopedia of Philosophy, â€Å"ethical claims are comprised of pseudo concepts which merely convey commands or feelings and do not contain any meaning (Marturano 2006, 1). Ethical statements remains important or significant because it is being use to persuade other people most specifically the receiver to perform or act in a certain way. In such case, ethical claims can be debated or can cause several disagreements and agreements but it can never comprise a logical understanding or reach any rational conclusion because normative claims cannot express the truth value of the statement. Thus, logical laws or basic rules of logic are inapplicable to moral statements (Hooker 1996, 3-5). By being a non-cognitivist, a person can deal with more relevant questions concerning reality. For instance, instead of dealing with the question of truthfulness of the statement â€Å"abortion should not be permissible†, people would be more focused on assessing the claim with respect to its effect or to its general utility. If abortion is done what would be its effect, thus basing the judgment on the factual outcome and not on mere assumption. To make this point clearer, consider the statement â€Å"genocide is wrong†, since it does not express any truth value, its assessment or its continuation would depend on its result. Non-cognitivism, by removing the truth value of normative statements has ended the dispute regarding the reality of an objective moral code or morality. This paved the way for moral relativism which favors the variation of moral codes in the different parts of the worlds at different times. This results to more respect to different cultures and traditions across national and ethnic boundaries. By denoting that moral statements are merely expression of approval/disapproval or sentiments, the non-cognitivist have also succeed in emphasizing the reason why there have been different reactions among different people regarding a certain moral issue. The varying reason as to why and how people view things differently. It also shows that moral statements cannot be true or false, thus they cannot be use to persuade other people in doing this or that. Moral realism on the other hand purports that moral statements is either true or false. The moral claim, â€Å"abortion is wrong† is either true or false. If this will be the case, there would be fixed moral codes that should apply to everyone else or at least every rational person in the planet. Yet, the relativity and subjectivity of moral statements seems to contradict the moral realist position because in different countries there were differing view regarding this matter and this is something that is prevalent in the reality in which we lived in. People does not agree on the same moral issue, most often they would argue differently depending on their position, biases, outlook, experiences and so on. The reason why I agree that â€Å"abortion is wrong† would be very different from your or his or her reason. In moral realism, people would continue to argue and debate over claims fruitlessly. In the end they would come up with a conclusion that is not far from being the decision of the â€Å"majority†. If moral realism are right in asserting that moral statements expresses truth value, then what people, specially influential and powerful ones would do is to persuade other people into believing that their statement is the right and whatever that contradicts their statement and purpose are wrong. Moral realism maintains that there can be â€Å"objective moral values† which contradicts the Non-cognitivist claims. However, moral realist failed to account what constitute the objective moral facts (Shafer-Landau 2005). They argued that â€Å"death penalty is wrong† can be accounted as either true or false simply because they believed that it is the same as any cognitive statement such as â€Å"it is dark†. Moral realist cannot prove that â€Å"death penalty is wrong is in fact true† for it differs from people’s opinion, perspectives and desire. There is no factual evidence that could actually prove that it is true (Stevenson1944, 15). The reality of the existence of moral facts is inaccessible to scientific inquiry and cannot be observed directly through our senses without appeal to our emotions, sentiments or feelings.

He was straight to the point but I didn t find him apprehensible like I did with the other authors, this may hold to make with the fact that this was written in the 1500 s. I understand that Chapman was a really intelligent adult male and a g reat author but his diction merely didn T seem to do sense to me and I couldn t truly experience what he was speaking about. With Gladstone s interlingual rendition it was reasonably much the same information, no debut like Graves and Fitzgerald, but the spelling was right so there wasn T any thinking being done, and a batch more clearer. He was stating the same things as Chapman but his words were simpler, and more apprehensible. Graves and Fitzgerald s interlingual renditions seemed a batch more descriptive than Chapman s and Gladstones. I was really visualizing the conflict in my head. The descriptive words were really good. As Graves negotiations about the bright sunshine glistening on the weaponries and adorned armour, I can see it in my head. That is the key to a great author. What besides helped was the debut in both these authors interlingual renditions, this was non given in neither Chapman s nor Gladstone s. The lone job I saw with Grave s interlingual rendition is that it was merely merely excessively short. There should hold been more written. This is where Fitzgeralds interlingual rendition comes in. I feel it was clear, it had a nice beat to it, great item, and a batch of information. Therefore Fitzgerald s interlingual rendition was the most effectual to me. It had everything that the other authors had lacked.

Full Body Burden Essay free essay sample

After the Mothers Day fire in nineteen sixty-nine, Rocky Hats began offering tours for the public. During the tour, each person receives a respirator and is dressed in laboratory smocks and booties. The tour guide tells the people to put on their respirators if an alarm sounds while walking through the corridors because this means that a particle of plutonium the size of a grain of pollen, if inhaled or taken into the body, can cause bone or lung cancer, leukemia, or genetic defects(leveler 157).Another type of cancer caused by plutonium contamination is of the brain. In nineteen seventy-eight, Dry. Carl Johnnys research reaches the public. He hows an evident pattern of large incidences of all cancers in every age group people in areas exposed to the Rocky Flats facility. It is also discovered that the workers at the plant have around eight times more brain tumors than is presumed.

He began working at the plant in nineteen seventy and after a year of working at the plant, he was transferred to Building 771. This was the plutonium processing building. Gable then learned to use a furnace that elated plutonium and he spent most of his workday with his head a few inches away from a sign that read: DO NOT LOITER. Just a short while after his transfer to Building 771, he was told to tear off a strip of tape from a tank that had been contaminated.He was tested and his hands, face, and hair measured 2,000 counts of alpha radiation per minute(leveler 184). After six years of working at Rocky Flats, he was tested again and this time his entire body measured more than one million counts per minute. The radiation had caused the chromosomes in his brain and blood to be altered and he plopped a large tumor on the side of his head. A third type of cancer that was common was leukemia. Dry. Johnson finds that the cancers found are mainly the same types that were found in the the survivors of Hiroshima and Nagasaki. Five years after Rocky Flats was built, there had been a sustainable rise in deaths in children from leukemia. Theses deaths were around double the national average. It was found that exposure to exterior ionizing radiation were related to an increase in leukemia. Effects of low-level radioactive contamination take several years to appear if the effect is leukemia. The International Agency for Research on Cancer (IIRC) found a relationship between leukemia and external radiation.

Meteorological Hazards in Aviation

Meteorological Hazards in Aviation Introduction Throughout its history, the aviation industry has had a close but unpleasant relationship with the vagrancies of weather (Vickers et al., 2001). Indeed, it has been proved that weather is the single largest contributor to delays and a foremost factor in aircraft disasters and incidents, implying that real-time weather information is substantially critical for hazardous weather avoidance in aviation operations (Witiw, Lanier Crooks, 2003).Advertising We will write a custom essay sample on Meteorological Hazards in Aviation specifically for you for only $16.05 $11/page Learn More Weather continues to exact its toll on the aviation sector, particularly when this argument is viewed in the context of past accidents that have been reported in mainstream media as caused by either meteorological hazards or a combination of human factors and weather elements (Broc et al., 2005; World Meteorological Association, 2007). The present paper critically discus ses some of the well known meteorological hazards in the aviation industry. Concept Definition Meteorology has been described as â€Å"†¦the science of the atmosphere, a sea of air that is in a constant state of flux† (Vickers et al., 2001, p. ix). Within this science exists a wide allay of weather/climatic conditions arising from natural interactions with other factors, products and byproducts, but which triggers a set of hazards that may prove disastrous to the aviator who must operate within the precincts of the atmosphere (Simpson et al., 2002). It is reported in the literature that no one is immune to the everyday oscillations of these meteorological hazards as they sweep across huge sections of the globe before dissipating (Vickers et al., 2001). Meteorological Hazards in Aviation Available literature demonstrates that there exists a multiplicity of weather conditions that qualify as hazards in aviation due to the scope and context of the dangers they present to th e industry (Broc et al., 2005). Some of the most predominant ones include icing, volcanic ash, poor visibility, windshear, heavy rains, lee waves, fronts, thunderstorms, cold weather and deformation zone (World Meteorological Association, 2007). This section samples a few of these meteorological hazards in aviation. Windshear Witiw et al (2003) describe the windshear as â€Å"†¦a sudden shift in wind direction, velocity, or both† (p. 131). These authors also report that the most aggressive expression of the condition occurs in a microburst, which is an intense downburst of cool air generated by, or released from, a large convective cloud. The World Meteorological Organization (2007) defines windshear as â€Å"†¦layers or columns of air, flowing with different velocities (i.e. speed and/or direction) to adjacent layers or columns† (p. 1). Windshear is a foremost hazard for low, slow flying aircraft in either the approach or departure phases due to the complica ted wind patterns occasioned by the downdrafts. As the aircraft glides through the microburst it stumbles upon intense headwinds accompanied by a substantial increase in aerodynamic drift and successive severe downdrafts, ultimately causing it to experience a rapid loss of lift and crash into the ground (Witiw et al., 2003).Advertising Looking for essay on aviation? Let's see if we can help you! Get your first paper with 15% OFF Learn More Consequently, some of the detrimental hazards caused by windshear include: 1) loss of aerodynamic lift and airspeed, making the aircraft to plunge into the ground before corrective action is taken by the flight crew, 2) turbulence especially in light aircraft, and 3) structural damage to the aircraft (Witiw et al., 2003; World Meteorological Organization, 2007). In the United States, the National Transport Safety Board (NTSB) database reveals that nearly 250 accidents involving U.S. aircrafts have been attributed to windshe ar, with 30 of them reported as major (Witiw et al., 2003). Thunderstorms Although one of the most beautiful atmospheric phenomenon (Harding, 2011), extant literature demonstrates that â€Å"†¦no other weather encountered by a pilot can be as violent or threatening as a thunderstorm† (Vickers et al., 2001, p.34). Indeed, thunderstorms generate more threats to the aviation industry and it is always important for the flight crew, air transport safety agencies, meteorologists and other interested stakeholders to not only understand their scope and context, but also how to deal with them effectively. Thunderstorms are generated by the coming together of several ingredients, including: 1) unbalanced air mass, 2) atmospheric moisture in the low levels, 3) some triggering mechanism, e.g. daytime heating or upper level cooling, and 4) other related meteorological vagrancies such as windshear (Vickers et al., 2001). These ingredients interact through a process called convection ( transport of heat energy) to produce thunderstorms that basically attempt to correct the imbalance generated when the atmosphere becomes heated unevenly (Harding, 2011). It is important to note that there exist different types of thunderstorms that affect the aviation industry. Some of the most common types of include: 1) air mass thunderstorms – form within a worm, moist air mass and are non-frontal in character, 2) frontal thunderstorms – form either as a result of a frontal surface lifting an unbalanced air mass or a stable air mass becoming unbalanced due to the lifting, 3) squall line thunderstorms – aggressive combinations of strong winds, hail, rain and lighting, 4) orographic thunderstorms – occur when moist, unbalanced air is forced up a mountain slope at high pressure, and 5) nocturnal thunderstorms – develop during or persist all night (Vickers et al., 2001). Thunderstorms have the capability to generate hazards that can cause untold suf fering in the aviation industry. For instance, â€Å"†¦all thunderstorms can produce severe turbulence, low level windshear, low ceilings and visibilities, hail and lighting† (Harding, 2011, p. 1).Advertising We will write a custom essay sample on Meteorological Hazards in Aviation specifically for you for only $16.05 $11/page Learn More It is not uncommon to hear news of aircraft that get lost in severe thunderstorms or helicopters that get struck by lightning, implying that each of these conditions can be potentially catastrophic (Broc et al., 2005). Other hazards generated by thunderstorms include ruthless clear icing, extremely profound precipitation, and dangerous electrical releases within and near the thunderstorm cell (Vickers et al., 2001; World Meteorological Organization, 2007). Visibility It is reported in the literature that reduced visibility is the meteorological element which impacts aviation operations the most through cancelled flights, accidents as well as incidents (Vickers et al., 2001). These authors posit that the aviation industry uses various types of visibility, which include: 1) horizontal visibility – the furthest visibility achieved horizontally in a particular direction by referencing objects or lights at known distances, 2) prevailing visibility – the ground level visibility which is common to one-half or more of the horizon loop, 3) vertical visibility – the maximum visibility achieved by looking vertically upwards into a surface-based impediment such as mist or snow, 4) slant visibility – visibility achieved by looking forward and downwards from the cockpit of the aircraft, and 5) flight visibility – the standard range of visibility at any given time forward form the cockpit of an aircraft in flight. Reduced visibility is caused by a multiplicity of factors, including lithometers (dry particles suspended in the atmosphere, such as haze, smoke, sand and dus t), precipitation, fog (radiation fog, frontal fog, steam fog, advection fog and ice fog), as well as snow squalls and streamers (Vickers et al., 2001). As already mentioned, low visibility leads to flight cancellations, fuel wastage as aircraft is unable to land in designated destination, aircraft damage in midair collisions, and deaths resulting from aircraft accidents (Watson, Ramirez Salud, 2009). Volcanic Ash The 2011 massive flight cancellations in Europe that were triggered by airborne volcanic ash from the Grimsvotn volcano in Iceland prove that volcanic ash is a major hazard to aviation safety at all levels. Indeed, â€Å"†¦like fine-grained mineral dust, volcanic ash affects radiative forcing and climate, public health, vegetation, and can cause property damage and disruption to community infrastructure† (Hadley, Hufford Simpson, 2004, p. 829). The major problem with volcanic ash emanates from the fact that onboard aircraft radars are unable to detect concent rated ash within or near eruption plumes, leading to life-threatening encounters, huge losses in flight cancellations, and aircraft damage (Simpson et al., 2002).Advertising Looking for essay on aviation?

Get your first paper with 15% OFF Learn More The damage caused by volcanic ash often calls for expensive repairs or total equipment replacement, thus it is of outmost importance for flight crew to ensure total avoidance of the ash for flight safety. What’s more, the pumice material contained in volcanic dust acts to abrade the aircraft’s leading edges (i.e. wings, struts, and turbine blades) to a point where the aircraft can cause a fatal accident if no replacement is done (Vickers et al., 2001). Icing or Icy Weather Schreiner (2007) acknowledges that â€Å"†¦icy weather, including ice pellets and cloud droplets that freeze on contact, affects air travel all over the world, especially during colder months† (p. 152). Aircraft icing takes place when supercooled water droplets from the atmosphere hit an aircraft whose body temperature is colder than 0oC, crystallizing into ice and occasioning serious detrimental effects that often expose an aviator to the real probability of causing an accident (World Me teorological Association, 2007). The two most important meteorological factors that affect icing include liquid water content of the cloud and temperature structure in the cloud. Some of the detrimental effects caused by icing include: 1) restriction of visibility as windshear glazes over, 2) disturbance of the smooth laminar air flow over the aircraft wings, occasioning a decrease in lift and an increase in the stall speed, 3) increase in aircraft weight and drug, hence decreasing fuel efficiency, and 4) incomplete or absolute blockage of pitot heads and static ports, thereby allowing erroneous instrument readings (Vickers et al., 2001). A study conducted by the NTSB demonstrates that approximately 819 people lost their lives in accidents linked to in-flight icing between 1982 and 2000 (Schreiner, 2007). Heavy Rain Although there is no agreed upon definition regarding rainfall intensity, heavy rainfall is defined in the literature as rates in excess of 4 mm per hours, while heavy s howers are perceived as rates in excess of 10 mm per hour (World Meteorological Association, 2007). Heavy showers, which are often associated with thunderstorms, qualify to be seen in the context of a meteorological hazard to aircraft due to their capacity to not only reduce physical and canopy/windscreen visibility, but also permit water ingestion into the cabin/cockpit/engine partitions of light, non pressurized aircraft, thereby endangering the effective and efficient operations of electronic equipment within the aircraft. There exists a possibility for aircraft turbine engines to ‘flame out’ and cause destructive effects under conditions of extreme rainfall and subsequent water ingestion (World Meteorological Association, 2007). Additionally, it has been reported that intense rainfall affects aircraft braking mechanism and may cause the aircraft to skid off the runway during takeoff and landing (Vickers et al., 2001). Duststorms/Sandstorms Duststorms and sandstorms, according to the World Meteorological Association (2007), are regions of raised dust and sand due to intense wind activity. The particles are propelled to different altitudes depending on the speed, instability and resolution of the wind flow, in line with the principle that smaller and lighter elements are lifted more readily and to much more elevated altitudes than weighty elements. Duststorms and sandstorms bring potentially destructive outcomes in aviation, such as reduced visibility, reduction of engine power in the event of dust and sand ingestion into aircraft engines, costly repairs, and aircraft crash in the event of a complete engine lockdown (Hadley et al., 2004; World Meteorological Association, 2007). Conclusion The paper set out to critically discuss some of the well known meteorological hazards in the aviation industry. It has been sufficiently demonstrated how normal meteorological processes, such as windshear, thunderstorms, visibility, volcanic ash, icing, heavy r ain, as well as duststorms and sandstorms, operate to become potential hazards in aviation. The potentially destructive outcomes arising from the different meteorological processes have been discussed at length, with the results demonstrating that many meteorological hazards lead to loss of life through aircraft accidents, loss of profits through frequent flight cancellations and rescheduling, loss of aircraft through structural damages, as well as costly repairs. It should therefore be the task of meteorology experts to conduct intense awareness campaigns in the aviation industry regarding the serious issues posed by meteorological vulnerabilities.

Article on How God got Started - Essay Example According to Wells, the whole incident regarding God’s instruction to Abraham to sacrifice his son was a test of the latter’s faith. Hence faith, according to Wells was a Jewish invention, which later on branched in Christianity and Islam. And while all of this was happening, science and logic were advancing at an alarming rate with the ancient Greeks at the helm of the onslaught. He adds that pure reason and logic have always collided with the concept of pure, blind faith despite the attempts of scholars to â€Å"‘reconcile’ them through the ages,† he says. So it is established, he points out, that faith and reason do not get along very well together. Moving on, he notes that surprisingly enough, the evolution and progress of faith can be charted in the rise of reason itself. He says that this theory gives psychological insights into the clash of faith with reason and vice versa. Even though faith is attributed to monotheistic religions, polytheisti c religions such as Hinduism and Buddhism also use this term to define their beliefs.

Ion Drive Propulsion: An Overview

Ion Drive Propulsion: An Overview TANG,YOUHENG Ion Drive propulsion, also called ion engine, which is a technology that involves gas ionization and can be used instead of standard chemicals. Give an electrical charge or ionize the gas xenon, which is like neon or helium, but heavier, the ionized gas can be electrically accelerated a speed of about 30km/s by the electric field force. When xenon ions are emitted at such high speed as exhaust from a spaceship, the spacecraft can be pushed in the opposite direction. The ion engine was firstly demonstrated by Emst Stuhliger, the German-born NASA scientist. Then at NASA Lewis Research Center (now called Glenn research center) from 1957 to the early 1960s IDP was developed in form by Harold R.Kaufman. Moreover, the ion drive propulsion was first demonstrated in space in â€Å"Space Electric Rocket Test (SERT)† I and II by NASA Lewis Research Center. The SERT-1, which is the first test was launched in July 20, 1964, proved the technology operated as predicted in space successfully. Furthermore, the second test SERT-II, which was launched on February 3rd 1970, verified the thousands of running hours operation of two mercury ion drive propulsions, though IDP were seldom used before the late 1990s. â€Å"Electric propulsion works by using electrical energy to accelerate a propellant to much higher velocities than is possible using chemical reactions. The most common propellant used in ion engines is xenon. Early ion engines used mercury and cesium, but they proved hard to work with. At room temperature, mercury is liquid and cesium is solid; they both must be heated to turn them into gases. Also, as mercury or cesium exhaust cooled, many of their atoms would condense on the exterior of the spacecraft, contaminating solar cells and instruments. Eventually researchers turned to xenon as a cleaner, simpler fuel for ion engines.† (De Felice, 1999). For IDP’s operation system, it uses an electric field to accelerate charged atoms or molecules to a high velocity. Ion thrusters generally use a cathode to generate a stream of electrons, which form an electric circuit with a positively charged ring the anode. A small magnetic field is used to aid this process (electrons spiral around the magnetic field lines, increasing the chance of electron-atom collisions). The ionized gas is accelerated out of the thruster and drifts towards an extraction grid system, so it can produce thrust. A neutraliser similar to the cathode is used to generate free electrons and balance the overall space charge of the outgoing beam so that the spacecraft does not charge itself up. To deal with this problem NASAs Deep Space 1 probe is testing a new type of ion thruster. The following description of DS-1s ion thrusters is from the official DS-1 Website: â€Å"Its ion propulsion system (IPS) utilizes a hollow cathode to produce electrons, used to ionize xenon. The Xe+ is electrostatically accelerated through a potential of up to 1280 V and emitted from the 30-cm thruster through a molybdenum grid. A separate electron beam is emitted to produce a neutral plasma beam. The power-processing unit (PPU) of the IPS can accept as much as 2.5 kW, corresponding to a peak thruster operating power of 2.3 kW and a thrust of 92 m N. Throttling is achieved by balancing thruster and Xe feed system parameters at lower power levels, and at the lowest thruster power, 500 W, the thrust is 20 m N. The specific impulse decreases from 3100 s at high power to 1900 s at the minimum throttle level. (De Felice, 1999)† Mostly, IDP is being used in aerospace application. Here are a couple of simple examples. Deep Space 1 which is a spacecraft of the NASA New Millennium Program dedicated to testing a payload of advanced, high risk technologies.Also it is the first spacecraft which used ion drive propulsion. Hayabusa which is an unmanned spacecraft developed by the Japan Aerospace Exploration Agency (JAXA) to return a sample of material from a small near-Earth asteroid named 25143 Itokawa to Earth for further analysis and used xenon ion engines Dawm which is a space probe launched by NASA on September 27, 2007, to study the two most massive objects of the asteroid belt–the protoplanet Vesta and the dwarf planet Ceres. It is the first NASA exploratory mission to use ion propulsion to enter orbits. There are three advantages of Ion Drive Propulsion which can probably explain why IDP is being used. First, it uses much less propellant than chemical rocketry so it may promise better reliability and simplicity than chemical rocketry or, from another perspective, it gets much more mileage out of a given quantity of propellant. Third, it could use 100% lunar or asteroid derived propellant. IDP can push a spacecraft up to about ten times as fast as chemical propulsion comparing IDP with chemical propulsion under the circumstances which ion propulsion is appropriate for. To sum up, the ion propulsion systems efficient use of electrical power and fuel enables modern spacecraft to travel farther, and it is cheaper than any other propulsion technology currently available. Ion drive propulsion is currently used for main propulsion on deep space probes and for station keeping on communication satellites. Ion thrusters expel ions to create thrust and can provide higher spacecraft top speeds than any other rocket which is available currently. In addition, the top speed of ion drive propulsion is startling. By using the principle of relativity, a physical situation could be analyzed from any reference frame as long as it moves with some constant speed relative to a known inertial frame. As a function of the proper time Ï„ experienced on the rocket, the acceleration of the rocket is a (Ï„),in Newtonian mechanics there is a quantity which increases the way velocity called the rapidity of the rocket . The rapidity ÃŽ ¸ will be ÃŽ ¸(Ï„)=∠« Ï„ 0 a(Ï„)dÏ„ The velocity is then v(Ï„)=tanhÃŽ ¸ . If a=g ,v(Ï„)=tanh(gÏ„) So if one year has passed on the rocket, the time on Earth will be tanh(1.05)=0.78C which means 78% of light. Since the limit of tanh is one as τ→∞, so the velocity of rocket will never get light speed. A more important limiting factor is the fuel. Fusion isnt a way around this because of E=mc^2 there is a limited energy can be calculate from a given mass of fuel. If a fraction (f) of the rocket is fuel, if all the fuel are burned, the momentum of the rocket will be ÃŽ ³m(1−f)ÃŽ ², with m the original mass. The conservation of momentum and energy give m=ÃŽ ³m(1−f)+E fuel 0=ÃŽ ³mÃŽ ²(1−f)+p fuel ÃŽ ²=−p fuel m−E fuel According the formulas and result shows that the fuel and rocket go opposite directions. To maximize ÃŽ ², make p fuel as large as possible and subject to a fixed E fuel so assume the fuel is massless with ÃŽ ² fuel =1 p fuel =−E fuel . ÃŽ ²=1−(1−f) 2 1+(1−f) 2 à £Ã¢â€š ¬Ã¢â€š ¬Ãƒ £Ã¢â€š ¬Ã¢â€š ¬ To sum up, even the fuel has 50% of the rockets original mass it just can get 3/5C. Researching in the area of ion propulsion is pushing the envelope of propulsion technology. To achieve higher power levels and speeds, longer durations advancements are being made. As new power sources become available, higher power thrusters will be developed that provide greater speed and more thrust. Nowadays, PPU and PMS technologies are being developed that will allow NASA to build lighter and more compact systems while increasing reliability. These technologies will allow humankind to explore the farthest reaches of our solar system also it will allow humankind to explore the farthest reaches which is out of our solar system.

Geography of Barbados :: Essays Papers

GEOGRAPHY OF BARBADOS Barbados is the most windward, or eastern of all the Caribbean islands. It’s the only island of the Caribbean that lies before the sixty-degree lateral line. Pedro a Campus, who arrived there in 1536, first discovered it. Pedro a Campus was sailing for Portugal at the time of his discovery. Upon his arrival he concluded that the island was uninhabited. The island remained this way until it was settled by the English in the later Seventeenth Century. The shape of the island, is somewhat of an irregular triangle. The circumference Of the island is approximately fifty-five miles around, with a length of twenty-one miles and a width of thirteen miles. Its size is approximately two and a half times the size of Washington D. C. Coral Reefs line almost the entire coast of the island, and at some points, are up to three miles seaward. This creates problems with navigating to and from the island. The northeastern portion of the island contains heights of 1000 feet, while the southeastern part has sandy beaches which are protected by the coral reefs. The highest elevation is Mount Hillaby, which is 1147 feet above sea level at the center portion of the country. The rest of the island is relatively flat, but elevates as it rises to the Central Highlands. Scotland River is the principal river which runs through the island. Other rivers include Joe’s River and the Indian River, along with a handful of natural springs, mainly Haggat’s. The island has a tropical climate and it rarely falls below seventy degrees Fahrenheit. The months of June to October are generally considered the â€Å"rainy† season. The island only occasionally suffers from the wrath of hurricanes. Another natural disaster that the people of the island encounter is periodic landslides.
