The Breakfast Club free essay sample

â€Å"The Breakfast Club† In the movie â€Å"The Breakfast Club† three interpersonal Terms that I found to be successfully use in the movie is. Interpersonal communication when the five high school student has to realize their mean to communicate with one another. Affection, the basic human need to be liked, this is when the tough guy that show himself not as one of the high school student, but show some affection and caring toward other as well, and Self-disclosure, an occasion when you just want to tell someone something about you, open up to others. While these students are in a completely different clique, they were not complete stranger to another; force to stay in detention, these five students got to know one another by sharing their stories and understanding one another. The breakfast club is one of a great movie that express the form of message to convey that communication can really bring the best out of one another. We will write a custom essay sample on The Breakfast Club or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the breakfast club we have, Allison, a weirdo, Brian, a nerd, John, a criminal, Claire, a prom queen, and Andrew, a jock, all of them are forced to stay in detention on Saturday, but by the end of the day, these kids found out that they have more in common to one another then they believed elsewhere. The interpersonal communication term will be selected from the scene where Clair and bender are going through one another purse. The scene represent that interpersonal communication is a very heavy influences on both of the characters. In the previous scene between Bender and Claire, they are very hostile toward one another, and very self-disclose. Claire ask Bender some very personal question from either her experience to his experience, and Bender will answer, but no matter what Bender answer he continuously sending Claire a message about himself, which is a form of communication. As for Bender he probably wouldn’t mind asking the same question after realizing about Claire disbelief in monogamy. We know that interpersonal communication is irreversible as well, after this scene has been showed to us, it would be very hard for Bender to argue that he believes in monogamy or for Claire to argue that she doesn’t. Then we come to Affection. Affection defines as a basic human need to be liked and esteemed. We take â€Å"The criminal† John Bender, he show now respect toward anyone more especially toward the teacher and school property, but  then John began to begin to show acceptance for himself and to his classmates during at the end of the movies, He began to accept that he need to accept the kind of person he is, and showing more and more kindness toward everyone else. During the whole movies, John always make fun of Claire â€Å" The Princess†, but at the end we all know that he doing it obviously doing it to shows compassion toward her. This showed he wanted to belong somewhere. He accepted himself by not showing as a tough guys throughout the entire show, but showing affection and caring. Lastly, Self-Discloser. â€Å" We are all pretty bizarre. Some of us are better at hiding it, that’s all† Andrew â€Å"The Breakfast Club†. Andrew describes the struggle to live up to his father expectation, and other opinion as well. Also of Bender stories of how his father abuse him. Both stories are somewhat very different among each other, but that is why Bender tell Andrew â€Å" I think my dad and your dad ought to get together and go bowling†. Both of them now are bonding together to fight against someone that are very self-discloser to them. Parent, peer pressure, boredom but mostly it is authority figures.

Uranium in a Nutshell

Uranium in a Nutshell Uranium is an extremely heavy metal, but instead of sinking into the Earths core it is concentrated on the surface. Uranium is found almost exclusively in the Earths continental crust, because its atoms dont fit in the crystal structure of the minerals of the mantle. Geochemists consider uranium one of the incompatible elements, more specifically a member of the large-ion lithophile element or LILE group. Its average abundance, over the whole continental crust, is a bit less than 3 parts per million. Uranium never occurs as bare metal; rather, it most often occurs in oxides as the minerals uraninite (UO2) or pitchblende (partially oxidized uraninite, conventionally given as U3O8). In solution, uranium travels in molecular complexes with carbonate, sulfate and chloride as long as the chemical conditions are oxidizing. But under reducing conditions, uranium drops out of solution as oxide minerals. This behavior is the key to uranium prospecting. Uranium deposits mainly occur in two geologic settings, a relatively cool one in sedimentary rocks and a hot one in granites. Sedimentary Uranium Deposits Because uranium moves in solution under oxidizing conditions and drops out under reducing conditions, it tends to gather where oxygen is absent, such as in black shales and other rocks rich in organic material. If oxidizing fluids move in, they mobilize the uranium and concentrate it along the front of the moving fluid. The famous roll-front uranium deposits of the Colorado Plateau are of this type, dating from the last few hundred million years. The uranium concentrations are not very high, but they are easy to mine and process. The great uranium deposits of northern Saskatchewan, in Canada, are also of sedimentary origin but with a different scenario of much greater age. There an ancient continent was deeply eroded during the Early Proterozoic Era some 2 billion years ago, then was covered by deep layers of sedimentary rock. The unconformity between the eroded basement rocks and overlying sedimentary basin rocks is where chemical activity and fluid flows concentrated uranium into orebodies reaching 70 percent purity. The Geological Association of Canada has published a thorough exploration of these unconformity-associated uranium deposits with full details of this still-mysterious process. At roughly the same time in geologic history, a sedimentary uranium deposit in present-day Africa actually grew concentrated enough that it ignited a natural nuclear reactor, one of Earths neatest tricks. Granitic Uranium Deposits As large bodies of granite solidify, the trace amounts of uranium become concentrated in the last bits of fluid left. Especially at shallow levels, these may fracture and invade surrounding rocks with metal-bearing fluids, leaving veins of ore. More episodes of tectonic activity can concentrate these further, and the worlds largest uranium deposit is one of these, a hematite breccia complex at Olympic Dam in South Australia. Good specimens of uranium minerals are found in the final stage of granite solidification- the veins of large crystals and unusual minerals called pegmatites. There may be found cubic crystals of uraninite, black crusts of pitchblende and plates of uranium-phosphate minerals such as torbernite (Cu(UO2)(PO4)2Â ·8–12H2O). Silver, vanadium and arsenic minerals are also common where uranium is found. Pegmatite uranium is not worth mining today, because the ore deposits are small. But they are where the good mineral specimens are found. The radioactivity of uranium affects the minerals around it. If you are examining a pegmatite, these signs of uranium include blackened fluorite, blue celestite, smoky quartz, golden beryl and red-stained feldspars. Also, chalcedony that contains uranium is intensely fluorescent with a yellow-green color. Uranium in Commerce Uranium is prized for its enormous energy content, which can be harnessed to generate heat in nuclear reactors or unleashed in nuclear explosives. The Nuclear Nonproliferation Treaty and other international agreements govern traffic in uranium to ensure that it is used only for civilian purposes. World trade in uranium amounts to more than 60,000 metric tons, all of it accounted for under international protocols. The largest producers of uranium are Canada, Australia and Kazakhstan. The price of uranium has fluctuated with the fortunes of the nuclear power industry and the military needs of various countries. After the collapse of the Soviet Union, large stores of enriched uranium have been diluted and sold as nuclear fuel under the Highly Enriched Uranium Purchase Agreement, which kept prices low through the 1990s. As of about 2005, however, prices have been climbing and prospectors are out in the field again for the first time in a generation. And with renewed attention on nuclear power as a zero-carbon energy source in the context of global warming, it is time to become familiar again with uranium.
