There is currently a substantial market for hydrogen in a variety of industrial applications. It is a raw material to produce chemicals such as ammonia and hydrogen peroxide, it is used as a reducing agent in various processes such as steel refining and float glass production, and it is even used in food processing such as the hydrogenation of vegetable oils. A particularly large consumer of hydrogen is the petroleum sector as demand for low sulfur fuels increases. This market for hydrogen is increasing as these industries grow, particularly in high growth economies.…

1. A double blind study was conducted measuring the effects of ritanserin on cocaine addiction. Both a placebo and ritanserin group were established. Both groups were given cocaine cues while measurements of their heart rate, skin temperature, and skin resistance were taken in two sessions, four weeks apart. Self reports (quantitative scales of qualitative characteristics such as mood, craving intensity, etc.) were also taken in order to determine levels of craving. Ritanserin groups showed a significant difference in decreasing skin temperature and qualitative self reports. However, the results were not solid enough or free of confounding variables to determine that ritanserin is an effective method of reducing cocaine craving.…

Today, science is everywhere in our world. From backyard science projects to launching rockets into space, science is a hard thing to avoid. Today, science is used in many important things, but the periodic table of elements is among one of the most important discoveries yet. It proves that our earth and galaxy are made of elements and that they aren't just piles of nothing. Without the elements there would literally be nothing and the galaxy wouldn't exist. Also, science helps us figure out and solve complex problems like preventing accidents such as the Hindenburg blimp accident. Overall, science is everywhere and in this essay I am going to discuss hydrogen and the Hindenburg blimp accident.…
Baz Luhrmann transformed William Shakespeare's play of Romeo and Juliet, to a fast moving, modern adaptation, the film Romeo + Juliet. Luhrmann has transformed the context, setting, costume, music, language and the themes in Romeo and Juliet. Although Luhrmann has transformed some things, he has redefined the love story gone wrong and made a film about the corruption in society. Luhrmann has transformed the original Shakespeare play using various film techniques and language devices, such as in the prologue, and the ballroom scene. He appropriated the text to fit into the world of love and violence that Luhrmann has created.…
While natural gas has had a direct negative effect on the Ozone Layer, scientists have found an element that allegedly causes no additional threat to global warming, hydrogen fuel cells. The negative effects that oil has had on the environment have been a major factor in the manufacturing of cars that contain hydrogen fuel cells. Recently, multiple car dealerships have begun manufacturing cars that contain replacements of the internal combustion engine with hydrogen fuel cells. Jim Motavalli, editor of E. Magazine, writes, “A hydrogen car emits no pollution or global warming gases, aside from what might have resulted from producing the hydrogen itself,” (105). This is what scientists have been seeking to accomplish. Motavalli also states, “The only byproducts are heat and water,” (105). Given these two facts, one can observe the advanced technology hydrogen fuel cells may have to offer. Because the exact emissions from the hydrogen fuel cells are created through natural elements,…
The search for a renewable energy source has been a top priority to us a human race in the past decade. Many ideas have come in the form of wind, solar, and nuclear power, all having their own drawbacks. But, the one that will be focused upon in this analysis is hydrogen as a source of fuel, and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us, how it might hurt us, and whether it is worth pursuing from an ethical stance.…
Even though fuel oil is classified as a flammable liquid, most fuels will not burn easily in a liquid state. If you were to drop a lit match in a container of fuel oil, it would PROBABLY go out almost immediately (don’t try this!). In order for fuel oil to burn, it must first be transformed from a liquid to a vaporised state ~ atomised. Atomisation increases the exposure of the fuel to the oxygen in the air; this promotes combustion.…
Calories: The name calorie is used for two units of energy. Although these units are part of the metric system, they have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. Calories are also most known to be used in foods and diet, which is key to athletes.…

A fuel system purpose is to store, transfer, and then to mix the fuel with air. The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air, vaporized, and burned to produce energy.…
The purpose of this experiment is to derive the universal gas constant for gases experimentally by collecting gases from the neutralization reaction and determining the volume and pressure of the gas and then the partial pressure of the gas formed. The single displacement reaction between magnesium metal and hydrochloric acid will be used to generate the hydrogen gas:…
