Dennis Nilsen The Kindly Killer with Rational Sickness Professor Ramos Blog

Dennis Nilsen The Kindly Killer with Rational Sickness â€Å"Mental Illness is the only disease that can make you deny its own existence. Certainly, the Idea that the brain can deny its own illness is a frightening thought.†- (Tracy). No matter how sharp the dagger, I believe a serial killer’s most potent weapon is his character. We don’t truly understand what someone is going through, what pain or problems they’re facing, but what we can understand is a grin. We often beg question what causes serial killers to kill? The answer is not so simple. Simply because the answer is a combination of causes, ranging from personal, life changing events to small, minor events. Sometimes these events generate something else thereby strengthening the violent behavior. Take the notorious â€Å"The Muswell Hill Murderer†. Before the news of his atrocities, Nilsen was a hardworking, well like man in his community. He, just like any other normal person blended into society and hid his terrors. However, behind that kindly person, Nilsen is responsible for the torture, rape, and murder of 12 to 15 young men (Biography). His tactic was to invite them to his house and have drinks after they fell asleep, he strangled them and later cut their bodies apart same way Jeffery Dahmer another serial killer. Before diving into in of all the causes that drove Dennis Nilsen to become an infuriated man, it is important to shine light on his origin story, because even the serial killer has one. Dennis Andrew Nilsen was born on November 23, 1945 in Fraserburgh, Aberdeenshire, Scotland (Wikipedia). Like most known killers, Dennis had a troubled childhood from abusive father, from the loss of his grandfather, not able express his sexuality and the controlled he desired, and was this a mixture of monster in the making. Was this what drove Dennis Nilsen â€Å"The Muswell Hill Murderer† gone to a disturbing rampage cause him to do sinister act to those men’s. The first red flag was a rough childhood. According to the British Police, â€Å"Neglect and abuse in childhood have been shown to contribute to an increased risk of future violence† (Serial Killers). Neglect and abuse, how typical of modern-day mass shooters. Whether or not you become prone to violence in the upcoming, I think we can all agree that having a weak relationship with your parents will set you back will take a toll on how you grow up. The world of Criminal Justice even states that â€Å"Serial murderers often come from broken homes and were child victims of parental physical abuse† (Serial Killers). His father was a Norwegian soldier who had travelled to Scotland in 1940 as part of the Free Norwegian Forces, following the German occupation of Norway (Wikipedia). Olav Nilsen did not view married life with any importance, being preoccupied with his duties with the Free Norwegian Forces and making little attempt to spend much time with his family or find a new home for his wife. Olav was an alcoholic and abusive to his wife and had affairs that cause his mother to have a mental break down had move back with her parents due trouble that she had with Olav (Serial Killers). Dennis father was not close to his all three children he conceive with Dennis mother Elizabeth. He admits that the drinking and the abuse they received from his father did cause him to drink and neglect everyone else. Having growing up without a father Dennis got close to his grandfather and whiteness death at a very young age and not knowing what â€Å"DEATH† means can cause a mix of emotion. Dennis grandfather was like a father to him they got very close they took long walks around Scotland Peer, they went fishing together, and did a lot work together. When he found out that his grandfather had passed away he was coming back from school. His mother Elizabeth was in the kitchen and told him â€Å"If you wanted to see your Grand Dad† Dennis was very happy that his grandfather was here to see him his mother Elizabeth told Dennis with a series look on her face well he’s here (Serial Killers). What the documentary states when they interview Dennis â€Å"When he saw his grandfather on the kitchen table inside this coffin that he states that was the first time he witness death† he was in state of shock (Serial Killers). He cried and had ask his mother â€Å"where has he gon e† and his mother had replied â€Å"to a better place† and Dennis responded by â€Å"if he went to a better place†¦ why didn’t take me with him.† (Serial Killers) In the documentary his psychiatrist stated witnessing his grandfather corps and the kitchen had shocked him. Having to whiteness something like Dennis had an effect on him. His mind he had known one else to talk to anymore he even stated that he wanted to take his own life so he could be close to his grandfather. At the onset of youth, Nilsen discovered he was homosexual, which initially confused and shamed of it. He kept his sexuality hidden from his family and his few friends. Because many of the boys to whom he was attracted had similar facial features as his younger sister, on one occasion he sexually fondled her, believing that his attraction towards boys might be a manifestation of the care he felt for her (Wikipedia). He made no efforts to seek sexual contact with any of the peers to whom he was sexually attracted, although he later said he had been fondled by an older youth and did not find the experience unpleasant. On one occasion, he also touched and stroked the body of his older brother as he slept (Wikipedia). As a result of this, Olav Jr. began to suspect his brother was homosexual and regularly belittled him in public referring to Dennis as hen (Scottish slang for girl) (Wikipedia). Nilsen initially believed that his fondling of his sister may have been evidence that he was bis exual. And later contribute to his victims since they were all men. Nilsen, actions made him a monster. Jeffrey Jerome Cohen’s Monster Culture, Thesis IV, The Monster Dwells at the Gates of Difference states, â€Å"The monster is difference made flesh, come to dwell among us.†(Cohen) When he committed these murders, he became different in society. He was able to kill people, have sex with them after death, slice them open and pull out their insides, and even keep their bodies around his household for comfort. Normally people do not do things like this. When stories like this get to your feet, it usually brings out abhorrence. So, then why is society fascinated with these types of monsters? There are so many biographies, documentaries, interviews, books, movies, and TV shows on serial killers for public to see. Cohen states in Thesis VI, Fear of the Monster is really a Kind of Desire, that, â€Å"More often, however, the monster retains a haunting complexity.†¦ â€Å"And will always dangerously entice.†(Cohen). People are dr awn in to hear the stories of who the monsters are and what the monsters have done because they want to satisfy a curiosity by understanding why someone would do such horrible things. So, the question that comes to mind is, what led Dennis Nilsen to kill? Mental illness played a big role. It caused him to have unhealthy thoughts he could not rid himself of, and the mix of alcohol and then a set of circumstances suddenly left him with no one in his life which easily broke his already unstable psychological condition. Taking a closer look into his life can bring a better understanding to why Dennis Nilsen turned to a life of murder. Nilsen characteristics was out of the ordinary people that new him couldn’t believe it, but he was someone who became a monster because of her vengeful spirit and mental illness. Study into the his life of Dennis Nilsen and the orders that lead Dennis down a road to his foreseeable transformation from kind heart soul to an indentation collecting killer leads one to believe that there was not just one event that caused this twisting into a life of atrocity but multiple contributing factors.   Factors such as the experience of dealing with the traumatic loss of his grandfather and his abusive father, also his sexuality and wanting control. These were contributed to the formation of a monster ‘Dennis Nilsen.’ Work Cited: Cohen, Jeffrey Jerome. â€Å"Monster Culture: Seven Theses.† From Monster Theory: Reading   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Culture.

3 Easy Ways to Set Ice on Fire

3 Easy Ways to Set Ice on Fire Have you ever wondered whether you could set ice on fire? These are instructions for how to make ice appear to burn and also instructions so that you can actually set it on fire. Making Ice Appear to Be on Fire Most of the photos you might see of burning ice were probably made using Photoshop, but you can get the appearance of burning ice very easily without resorting to image processing tricks. Get some glass cubes (craft stores carry them), set them on a surface that can withstand fire (metal pan, Pyrex, stoneware), pour something flammable over the ice, and set it alight. You can use 151 rum (ethanol), rubbing alcohol (try for 90% isopropyl alcohol, not the 70% alcohol stuff), or methanol (Heetâ„ ¢ fuel treatment from the automotive section of a store). These easy-to-obtain fuels burn cleanly, so they wont set off your smoke alarm (I know... I tried). If you want colored flames, you can add any of the usual flame colorants to the ethanol or rubbing alcohol. If you use methanol, try adding a little boric acid for a brilliant green flame. Use caution with methanol, since it burns very hot. One little display tip: You can give glass cubes the imperfect, crackled appearance of water ice b y setting one on fire and then tossing it (with tongs) into water after the fire goes out. The glass may shatter, but if you have the temperature just right youll just create internal fractures that look very pretty in photographs. Flaming Ice I basically told you how to set ice on fire when I explained how to make a flaming B-52 drink. High-proof ethanol (like 151 rum) or 90% isopropyl alcohol will float on the surface of water and mix with it so that as long as there is fuel, your ice will appear to burn. As the ice melts, it will extinguish the flame (methanol is highly toxic too). You can use ethanol on ice used for human consumption (or flaming ice cream drinks). Rubbing alcohol (isopropyl) and methanol are toxic and should only be used for decorative purposes. Really Burning the Ice You may be thinking it is impossible to burn ice. Strictly speaking, that is not true. You can burn ice, just not water ice. If you make ice cubes from any of the alcohols I have listed, you can burn them. For pure alcohol ice cubes, youll need a way to freeze the liquid down to about -100Â °C, give or take a few degrees depending on the specific alcohol. You dont need to get quite that cold for 75% alcohol/25% water ice, which will burn if you spritz it with a little liquid alcohol to get flammable vapor over the ice. You may be able to freeze the 75% solution over dry ice. Flaming Ice Safety Just remember two things: (1) If you want to ingest the flaming ice, only use food-grade ethanol, not some other fuel. (2) Methanol burns very, very hot! You can get away with using almost any surface if you use ethanol or isopropanol. You can even touch the flame briefly. However, the risk of getting burned or of your fire getting out of control are much higher using methanol because it produces so much heat. Is It Possible to Burn Water? The reason water is used to extinguish flames is because it has such a high heat capacity. Technically, you cant burn water because combustion is an oxidation process. In a sense, water is the product of the combustion of hydrogen. However, if you pass a sufficiently strong electrical current through water, it decomposes into its elements. The hydrogen gas is flammable, while the oxygen gas supports its combustion. If you have a flame or ignition source at the point of electrolysis, water will appear to burn. So, it follows you could make real water ice appear to burn. For this to occur, the ice would need to be floating in some liquid water. Electrolysis of the water to produce hydrogen and oxygen would yield flammable gas above the ice. Igniting the gas would make the ice appear to burn. Note this is a theoretical method of burning ice, not one youd want to try in a school science lab! Its much safer to burn hydrogen from electrolysis in bubbles or balloons than in the open.

Methods assignment - Research Paper Example Mekonnen and Harris (2006) is an empirical investigation whether â€Å"cause-related† and â€Å"affinity marketing† enhances the product’s appeal and provides product differentiation (p. 135). In particular, the study investigated whether â€Å"linking a commercial organisation’s product with a non-profit organisation enhances the product’s appeal and provides differentiation from rival offers† (Mekonnen and Harris 2006, p. 135). Mekonnen and Harris (2006, p. 135) articulated that the purpose or aim of their study is to investigate the efficacy of the premise of â€Å"affinity marketing†. The research objectives were not explicitly stated but it can be surmised that, implicitly, the research objectives covered identification of values associated with the use of affinity cards and how they affect the likelihood of donation. 2.0. Literature Review Based on a review of literature, Mekonnen and Harris (2006, p. 136) claim that â€Å"there are significant gaps in understanding consumer attitudes† towards products being sold by â€Å"cause-related marketing† and â€Å"affinity marketing†. ... 136). Mekonnen and Harris (2006, p. 135) declared their work as a challenge to the assumption â€Å"that linking a product to a non-profit organisation enhances its appeal and provides a basis for differentiation.† For Mekonnen and Harris (2005, p. 135), â€Å"the efficacy of this premise depends on the type of cause or affinity group.† Unfortunately, however, the review of literature of Mekonnen and Harris (2006) does not amount to an illustration of the â€Å"significant gaps in understanding consumers’ attitude† in the literature. It is not clear from the review of literature what the various studies have made or the findings they have reached on the relationship between â€Å"cause-related market marketing† and â€Å"affinity marketing† on one hand and product sales on the other. Perhaps there was no empirical study done at all prior on cause-oriented and affinity marketing prior to their study but this is not clear from the review of lit erature. However, because of the failure to illustrate what empirical studies have done or to explicitly clarify at least that no study has been done, the review of literature fails to identify precisely or to justify precisely the significance of the Mekonnen and Harris (2006) endeavour in the overall literature on the subject. The review of literature narrated that cause-oriented marketing has been conventionally characterised as being focused on short-term campaign initiatives (Mekonnen and Harris 2006, p. 136). It also pointed out that the affinity marketing is a sub-set of cause-related marketing (Mekonnen and Harris 2006, p. 136). However, citing the work of Berger and others in 1999, Mekonnen and Harris (2006, p. 136) clarified that â€Å"affinity marketing can

Dividend Policy decisions and Capital Structure decisions in relation Essay

Dividend Policy decisions and Capital Structure decisions in relation to Signaling THeory - Essay Example Usually the principal will offer a higher price than if she/he would not have received the signal. The assumptions underlying information asymmetry are that managers are better informed in relation to investors and will act to the best interest of current shareholders. The signaling theory assumes that managers and investors have same information but managers usually having better information. Thus, the managers would sell stock if overvalued and bonds if stock is undervalued. The investors clearly understand this and, therefore, view new stock sales as a negative signal. From the fact that information asymmetry is well known to all, how a company raises capital becomes a signal. The major implications of information asymmetry are: when the company’s prospects are poor the there is overvaluation of stock as nobody knows except the insiders, everything is financed with stock thus the company can raise more money at a lower cost; and when the company’s prospects are good then there is undervaluation of stock thus the company uses debt to finance. Overvaluation of stock assumes that once the stock falls, sharing of losses is by old and new stockholders favoring the old stockholders whereas undervaluation assumption is when the stock pri ces goes high only the old stockholders will benefit from the gains. This may be simply represented as follows: The signaling view in relation to dividend policy argues that changes in dividend amounts are signals of paramount importance to the investors about management’s changes expectation of future earnings (Duke,edu para 1). It is the belief of many that the amount per share companies’ pay as dividends is a clear indication of the management’s belief about future earnings. A decline in the dividend amount from a previous high amount is an indication that the management anticipates a decline in future earnings. It is a practice by most

Comic Books are not Trash :: miscellaneous

Comic Books are not Trash Comic books are cheap entertainment that trash the minds of our children. How often have I earned this. And I’ve disagreed with it every single time. If people were willing to go beyond that old stereotype, they would see that comic books are not that much different from other books. The thing is, as for many books, to choose wisely the ones we let our children read. Thus, you will see that comic books aren’t so bad. First, let us all remember that the authors, regardless of what type of writing they do, can always influence the minds of their young (and not so young) readers. After all, if you look at the storybooks written a few decades (and more) ago, you will find that a lot of them were sexist. For example, it was always the prince who saved Snow White, Cinderella and all the other princesses. Even if that is less true now, there are still some books that can negatively influence children. So if it is true that some comic books are sexist or violent, it is also true that some of them are, to put it simply, fine. It would be wrong to accuse all comic books of prejudice and violence, like it would be wrong to do the same with novels. In the same line of thought, one of the great things about books is that they can teach you a lot of things, whether it is about deep things or facts that you did not know; they broaden your horizon. Well, that is also true of some comic books. And it is not so surprising, when you think about it. For example, I had never heard of the country of Tanzania before I read a comic book in which that was the birth place of one of the main characters. As for more deep, philosophical things, even though it is less obvious, that can also be found. In a particular comic book title (but also in many others) the main subject in the stories is no understanding those who are born different from us. It can easily be related to racism. Thus, comic books, like books, can teach us great lessons. On a different note, it has often been said that literature is a form of art and that the writer is an artist and should be looked upon as such.

Geology Midterm Review

Introduction to Geology GEOL-101 Midterm 1 Review Based on the textbook: Understanding Earth, 6th Edition, by Grotzinger and Press CH 1: earth system Summary The human creative process, field and lab observations, and experiments help geoscientists formulate testable hypotheses (models) for how the Earth works and its history. A hypothesis is a tentative explanation focusing attention on plausible features and relationships of a working model. If a testable hypothesis is confirmed by a large body of data, it may be elevated to a theory. Theories are abandoned when subsequent investigations show them to be false.Confidence grows in those theories that withstand repeated tests and successfully predict the results of new experiments. A set of hypothesis and theories may become the basis of a scientific model that represents an entire system too complicated to replicate in the laboratory. Often models are tested and revised in a series of computer simulations. Confidence in such a model grows as it successfully predicts the behavior of the system. The elevations of Earth topography averages 1–2 kilometers above sea level for land features and 4–5 kilometers below sea level for features of the deep ocean.The principle of uniformitarianism states that geological processes have worked in the same way throughout time. Earth’s interior is divided into concentric layers (crust, mantle, core) of sharply different chemical composition and density. The layered composition of the Earth is driven by gravity. Only eight of the 100 or so elements account for 99 percent of Earth’s mass. The lightest element (oxygen) is most abundant in the surface crust and mantle, while the densest (iron) makes up most of what is found deep in the core. Earth’s major interacting systems are the climate system, the plate tectonic system, and the geodynamic system.The climate system involves interactions among the atmosphere, hydrosphere, and biosphere. The plat e tectonic system involves interactions among the lithosphere, asthenosphere, and deep mantle. The geodynamic system involves interactions within the central core that produce occasional reversals of Earth’s magnetic field. As the Earth cooled, an outer relatively rigid shell, called the lithosphere, formed. Dynamic processes driven by heat transfer, density differences, and gravity broke the outer shell into plates that move around the Earth at rates of centimeters per year.Major components (atmosphere, hydrosphere, biosphere) of Earth’s surface systems are driven mostly by solar energy. Earth’s internal heat energizes the lithosphere, asthenosphere, deep mantle, and outer and inner core. Terms and Concepts Asthenosphere Convection Core Continental lithosphere Continental crust Earth systems Geology Inner core Lithosphere Mantle Oceanic lithosphere Oceanic crust Plate tectonic system Principle of uniformitarianism Scientific method Topography CH 2: plate tecton ics Summary For over the last century some geologists have argued for the concept of continental drift based on: he jigsaw-puzzle fit of the coasts on both sides of the Atlantic the geological similarities in rock ages and trends in geologic structures on opposite sides of the Atlantic fossil evidence suggesting that continents were joined at one time the distribution of glacial deposits as well as other paleoclimatic evidence In the last half of the twentieth century the major elements of the plate tectonic theory were formulated. Starting in the 1940s (WWII), ocean floor mapping began to reveal major geologic features on the ocean floor.Then, the match between magnetic anomaly patterns on the seafloor with the paleomagnetic time scale revealed that the ocean floor had a young geologic age and was systematically older away from the oceanic ridge systems. The concepts for seafloor spreading, subduction, and transform faulting evolved out of these and other observations. According to the theory of plate tectonics, the Earth’s lithosphere is broken into a dozen moving plates. The plates slide over a partially molten, weak asthenosphere, and the continents, embedded in some of the moving plates, are carried along.There are three major types of boundaries between lithospheric plates: divergent boundaries, where plates move apart convergent boundaries, where plates move together and one plate often subducts beneath the other transform boundaries, where plates slide past each other Volcanoes, earthquakes, and crustal deformation are concentrated along the active plate boundaries. Mountains typically form along convergent- and transform-plate boundaries. Where divergent-plate boundaries are exposed on land, subsiding basins and mafic volcanism are typical.Various methods have been used to estimate and measure the rate and direction of plate movements. Today seafloor-spreading rates vary between a few to 24 cm per year. Seafloor isochrons provide the basis for reconstructing plate motions for about the last 200 million years. Distinct assemblages of rocks characterize eachtype of plate boundary. Using diagnostic rock assemblages embedded in continents and paleo-environmental data recorded by fossils and sedimentary rocks, geologists have been able to reconstruct ancient plate tectonic events and plate configurations.Driven by Earth’s internal heat, convection of hot and cold matter within the mantle, the force of gravity and the existence of an asthenosphere are important factors in any model for the driving mechanism of plate tectonics. Currently studies of the plate-driving forces focus on discovering the exact nature of the mantle convection. Questions being addressed include: Where do the plate driving forces originate? At what depth does recycling occur? What is the nature of rising Convection Currents? The assembly and subsequent break up of Pangaea represent a striking example of the effects of plate tectonics acting over ge ologic time.The story begins with the breakup of the ancient supercontinent of Rodinia 750 million years ago. Plate tectonic processes dispersed the fragments of Rodinia forming a system of ancient continents that existed from the late Proterozoic through much of the Paleozoic. Continued tectonic movement eventually resulted in a set of continental collisions and reformation of the ancient continents into Pangaea. Assembly was completed during the early Triasic, about 240 million years ago. Then, about 200 million years ago the rift that would evolve into the Atlantic Ridge began to open and the separation of Pangaea was underway.By the beginning of the Cenezoic, India was well on its way to Asia, and the Tethys sea that had separated Africa from Eurasia began to close into the modern inland sea that we know as the Mediterranean. Continued changes during the Cenozoic produced our modern world and its geography.

Minerals form when atoms or ions chemically bond and come together in an orderly, three-dimensional geometric array—a crystal structure. Chemical bonding may occur either as a result of simple electrostatic attraction (ionic bond) or electron sharing (covalent bond). The strength of the chemical bonds and the crystalline structure determine many of the physical properties, e. . , hardness, cleavage of minerals. Silicate minerals are the most abundant class of minerals in the Earth’s crust and mantle. Common silicate minerals are polymorphs of silicon ions arranged in either isolated tetrahedral (olivine), single chains (pyroxene), double chains (amphibole), sheets (mica), or three-dimensional frameworks (feldspar). There are three important groups of silicates: ferromagnesium silicates, e. g. , olivine and pyroxene—common in the mantle feldspar and quartz—common in the crust clay mineral—commonly produced by chemical weatheringOther common mineral classes include carbonates, oxides, sulfates, sulfides, halides, and native metals. A rock is a naturally occurring solid aggregate of minerals. A few rocks consist of only one mineral and a few others consist of non-mineral matter. The properties of rocks and rock names are determined by mineral content (the kinds and proportions of minerals that make up the rock) and texture (the size, shapes, and spatial arrangement of crystals or grains. There are three major rock types: Igneous rocks solidify from molten liqui d (magma); crystal size within igneous rocks is largely determined by the cooling rate of the magma body.Sedimentary rocks are made of sediments formed from the weathering and erosion of any pre-existing rock; deposition, burial and lithification (compaction and cementation) transform loose sediments into sedimentary rocks. Metamorphic rocks are formed by an alteration in the solid state of any preexisting rock by high temperatures and pressure. Terms and Concepts Anion Atomic mass Atomic number Carbonate Cation Cleavage Covalent bond Crystal Crystallization Electron sharing Electron transfer Isotope Magma Mineral Polymorph Precipitate Rock CH 4: igneous rocks SummaryIgneous rocks can be divided into two broad textual classes: coarsely crystalline rocks, which are intrusive (plutonic) and therefore cooled slowly finely crystalline rocks, which are extrusive (volcanic) and cooled rapidly. Within each of these broad textual classes, the rocks are subdivided according to their composit ion. General compositional classes of igneous rocks are felsic, intermediate, mafic and ultramafic, in decreasing silica and increasing iron and magnesium content. Figures 4. 1, 4. 2, 4. 3 and Table 4. 1 summarize common minerals and composition of igneous rocks.The lower crust and upper mantle are typical places where physical conditions induce rock to melt. Temperature, pressure, rock composition, and the presenceof water all affect the melting temperature of the rock: Increase temperature: not all minerals melt at the same temperature; refer to Figures 4. 6 and 4. 7, which explain how fractional crystallization results from Bowen’s reaction series. The mineral composition of the rock affects the melting temperature. Felsic rocks with higher silica content melt at lower temperatures than mafic rocks which contain less silica and more iron/magnesium.Lower the confining pressure: a reduction in pressure can induce a hot rock to melt. A reduction in confining pressure on the h ot upper mantle is thought to generate the basaltic magmas which intrude into the oceanic ridge system to form ocean crust; refer to Figure 4. 15. Add water: the presence of water in a rock can lower its melting temperatures up to a few hundred degrees. Water released from rocks subducting into the mantle along convergent plate boundaries is thought to be an important factor in magma generation at convergent plate boundaries.As subduction begins water trapped in the rock is subjected to increasing temperature and pressure. Eventually the water is released into sedimentary layers above where it melts parts of the overlying plate; refer to Figure 4. 16.

Sedimentary basins result from rifting, thermal sag, and flexure of the lithosphere. The sedimentary stages of the rock cycle involve the overlapping processes of weathering, erosion, transportation, deposition, burial, and diagenesis. Weathering and erosion produce the clastic particles and dissolved ions that compose sediment. Water, wind, and ice transport the sediment downhill to where it is deposited.Burial and diagenesis harden sediments into sedimentary rocks via pressure, heat, and chemical reactions. The two major types of sediments are clastic and chemical/biochemical. Clastic sediments are formed from rock particles and mineral fragments. Chemical and biochemical sediments originate from the ions dissolved in wate r. Chemical and biochemical reactions precipitate these dissolved ions from solution. Understanding the characteristics of sediments and modern sedimentary environments provides a basis for reconstructing past environmental conditions using the rock record.Sedimentary structures like bedding, ripple marks, and mud cracks, provide important clues about the sedimentary environment. Diagenesis transforms sediment into sedimentary rock. Burial promotes this transformation by subjecting sediments to increasing heat and pressure. Cementation is especially important in the lithification of clastic sediments. The classification of clastic sediments and sedimentary rocks is based primarily on the size of the grains within the rock. The name of chemical and biochemical sediments and sedimentary rock is based primarily on their composition.

Increases in temperature and pressure and reactions with chemicalbearing fluids cause metamorphism.Metamorphism typically involves a rearrangement (recrystallization) of the chemical components within the parent rock. Rearrangement of components within minerals is facilitated by: higher temperatures, which increase ion mobility within the solid state; higher confining pressure compacts the rock; directed pressure associated with tectonic activity can cause the rock to shear (smear), which orients mineral grains and generates a foliation; and chemical reactions with migrating fluids may remove or add mater ials and induce the growth of new minerals.The two major types of metamorphism are regional metamorphism, associated with orogenic processes that build mountains, contact metamorphism, caused by the heat from an intruding body of magma, and seafloor metamorphism, also known as metasomatism. Other less common kinds of metamorphism are: burial metamorphism, associated with subsiding regions on continents, high-pressure metamorphism, occurring deep within subduction zones and upper mantle, and shock metamorphism due to meteor impact; refer to Figure 6. 4.Metamorphic rocks fall into two major textural classes: the foliated (displaying a preferred orientation of minerals, analogous to the grain within wood) and granoblastic (granular). The composition of the parent rock and the grade of metamorphism are the most important factors controlling the mineralogy of the metamorphic rock. etamorphism usually causes little to no change in the bulk composition of the rock. The kinds of minerals an d their orientation do change. Mineral assemblages within metamorphic rocks are used by geoscientists as a guide to the original composition of the parent rock and the conditions during metamorphism.Metamorphic rocks are characteristically formed in subduction zones, continental collisions, oceanic spreading centers, and deeply subsiding regions on the continents.

Is Schizophrenia A Serious Mental Disease - 1797 Words

Literature review Research show that Schizophrenia is a very serious mental disease which 1.2% of the American population is affected by. There is not evidence on what causes this very chronic disease but researchers believe that a combination of genetics and environment contributes to development of the disorder. This is a disease that is said to begin in early adulthood, which is between 15 to age 25. Research shows that males become ill in their early teens to early adulthood. Men tend to get develop schizophrenia slightly earlier than women. Most males become ill at age 16 or 25 most females develop symptoms several years later. This disease is noticeably higher in women after age 30. Schizophrenia is quite possible the most dreaded†¦show more content†¦The â€Å"schizophrenic symptom-rich period â€Å"following the psychotic break is sometimes called the active-phase or, alternatively a period of florid psychosis. The term florid means flowering and the term is a metaphorical usage denoting that the psychosis is the end result or goal of the schizophrenic illness, just as the bloom is the end result or goal of a flowering plant. (DOMBECK, 2009) During my research I read about how there are some common myths about what this disease in. in a article I read says that people assume that schizophrenia meaning the person has multiple personalities which means the person asks like two different people but it said that it doesn’t not mean they do it means they an false sense reality. Schizophrenia and multiple personality disorders are two totally different mental conditions. Next is people with this are more than likely dangerous and become violent very easily. People with schizophrenia is unpredictable they are not violent. Also you will get this mental disorder if your parents have it. That’s is not even the case statistics show that you have a 10% chance of getting schizophrenia. Last but not least people assume because you have this disorder that you are not intelligent but research shows that yet they have trouble learning things like someone without they can be just as smart. When I looked up names I found that a noble peace
