Geology And Types Of Rocks: Igneous, Sedimentary Rocks (Essay Sample) Content: Name:Course:Instructor:Date:Types of rocksGeologists define a rock any coherent, naturally occurring substance generally composed of minerals. Rocks are grouped into three categories that are igneous rocks, Sedimentary rocks, and metamorphic rocks. Igneous rocksIgneous rocks are formed by the solidification of magma, a silicate liquid generated by partial melting of the upper mantle or the lower crust. Different environments of formation, and the cooling rates associated with these, create very different textures. There are two main groupings of igneous rocks: volcanic rocks and plutonic rocks. Volcanic rocks form when magma rises to the surface and erupts, either as lava or pyroclastic material. The rate of cooling of the magma is rapid, and crystal growth is inhibited. Volcanic rocks are characteristically fine-grained. Volcanic rocks at times show structures from their eruption, e.g. molded by shearing the lava as it flowing or banding flow, and exposed voids or cr acks that signify bolted gases. Plutonic rocks on the other hand develop when magma cools inside the Earth's crust. The degree at which magma cools is slow thus it allows growing of large crystals. Plutonic rocks are typically coarse-grained. Igneous rocks play a significant role in geology in the following:Their  HYPERLINK "https://en.wikipedia.org/wiki/Minerals" \o "Minerals" minerals give data and facts about the structure of the mantle, from which several igneous rocks are mined. It helps to know pressure and temperature situations that allow this mining. Their  HYPERLINK "https://en.wikipedia.org/wiki/Absolute_dating" \o "Absolute dating" actual ages can be acquired from several types of  HYPERLINK "https://en.wikipedia.org/wiki/Radiometric_dating" \o "Radiometric dating" radio dating and thus be related to adjacent geological  HYPERLINK "https://en.wikipedia.org/wiki/Stratum" \o "Stratum" strata, giving a time arrangement of occasions.Their features are normally ch aracteristic of precise tectonic surroundings, permitting tectonic reconstructions.They have vital mineral deposits: e.g., tin, uranium and,  HYPERLINK "https://en.wikipedia.org/wiki/Tungsten" \o "Tungsten" tungsten are generally linked with  HYPERLINK "https://en.wikipedia.org/wiki/Diorite" \o "Diorite" diorites and granites, whereas rocks of platinum and  HYPERLINK "https://en.wikipedia.org/wiki/Chromium" \o "Chromium"  are usually linked with  HYPERLINK "https://en.wikipedia.org/wiki/Gabbro" \o "Gabbro" gabbros.The environment of development generates typical textures which contribute to their identification. These textures are as follows:Phaneritic where this texture defines a rock with huge, simply observable, linking crystals of numerous minerals. The crystals rocks are casually dispersed. A phaneritic texture is normally created by the sluggish cooling and crystallization of magma liquid trapped inside the Earth's crust and is typical of plutonic rocks.Porphyritic texture defines a rock that has good crystals observable by the naked eye, established in a precise fine grained, called groundmass. It results when magma has slowly cooled and crystallized inside the Earth's crust and suddenly erupting at the surface, making the remaining uncrystallised magma to cool fast. Most volcanic rocks experience this characteristic...Aphanitic texture defines very fine grained rock where separate crystals rocks are only visible with the help of a microscope, for instance the rock is generally groundmass. It is normally results when magma comes out of the Earth's surface and then cools too rapidly for huge crystals to develop. This texture is usually revealed by certain volcanic rocks.Eutaxitic texture defines a rock with a planar material in which compressed  HYPERLINK "javascript:setCookie('pumice','rhyolite.html');" pumice clasts are usually bounded by a fine grained ground mass of the sintered ash. The compressed pumice clasts are lens-shaped in cros s-section and are normally known as fiamme. In addition this texture develops when hot, pumice-rich substance explosively erupts and then flattened by overlying plastic plate substance that is still hot.The chemical structure of the magma decides which  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/index.html" minerals will form and in what sizes they will transpire. Therefore, identification of the minerals present in the rock is a significant stage in being able to properly classify the rock. Magmas that are relatively low in silica crystallize  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/olivine.html" olivine, pyroxene and calcium-rich  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/plagioclase.html" plagioclase, while magmas that are high in SiO2 crystallize  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/quartz.html" quartz, sodium-rich  HYPERLINK "ht tps://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/plagioclase.html" plagioclase,  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/orthoclase.html" orthoclase,  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/biotite.html" biotitic and  HYPERLINK "https://flexiblelearning.auckland.ac.nz/rocks_minerals/minerals/hornblende.html" hornblende. Thus, igneous rocks can be divided into mafic and felsic types. Mafic rocks are normally darker, and have higher loads of  HYPERLINK "javascript:setCookie('mafic','../minerals/physical.html');" mafic minerals. Felsic rocks are normally lighter in color, having a higher quality or degree of  HYPERLINK "javascript:setCookie('felsic','../minerals/physical.html');" felsic minerals.Sedimentary rockSedimentary rocks are usually the result of the erosion of current rocks. Eroded or worn out material adds as sediment, either in the land or sea, and is then suppressed, compres sed and cemented resulting in the formation of sedimentary rock.

Abelard and Heloise The Legacy of Their Love

Abelard and Heloise are one of the most celebrated couples of all time, known for their love affair and for the tragedy that separated them. In a letter to Abelard, Heloise wrote: You know, beloved, as the whole world knows, how much I have lost in you, how at one wretched stroke of fortune that supreme act of flagrant treachery robbed me of my very self in robbing me of you; and how my sorrow for my loss is nothing compared with what I feel for the manner in which I lost you. Who Abelard and Heloise Were Peter Abelard (1079-1142) was a French philosopher, considered one of the greatest thinkers of the 12th century, though his teachings were controversial, and he was repeatedly charged with heresy. Among his works is Sic et Non, a list of 158 philosophical and theological questions. Heloise (1101-1164) was the niece and pride of Canon Fulbert. She was well-educated by her uncle in Paris. Abelard later writes in his autobiographical Historica Calamitatum: Her uncles love for her was equaled only by his desire that she should have the best education which he could possibly procure for her. Of no mean beauty, she stood out above all by reason of her abundant knowledge of letters. Abelard and Heloises Complicated Relationship Heloise was one of the most well-educated women of her time, as well as a great beauty. Wishing to become acquainted with Heloise, Abelard persuaded Fulbert to allow him to teach Heloise. Using the pretext that his own house was a handicap to his studies, Abelard moved into the house of Heloise and her uncle. Soon enough, despite their age difference, Abelard and Heloise became lovers. But when Fulbert discovered their love, he separated them. As Abelard would later write: Oh, how great was the uncles grief when he learned the truth, and how bitter was the sorrow of the lovers when we were forced to part! Their separation didnt end the affair, and they soon discovered Heloise was pregnant. She left her uncles house when he was not at home, and she stayed with Abelards sister until Astrolabe was born. Abelard asked for Fulberts forgiveness and permission to secretly marry Heloise, to protect his career. Fulbert agreed, but Abelard struggled to persuade Heloise to marry him under such conditions. In Chapter 7 of Historia Calamitatum, Abelard wrote: She, however, most violently disapproved of this, and for two chief reasons: the danger thereof, and the disgrace which it would bring upon me... What penalties, she said, would the world rightly demand of her if she should rob it of so shining a light! When she finally agreed to become Abelards wife, Heloise told him, Then there is no more left but this, that in our doom the sorrow yet to come shall be no less than the love we two have already known. In regard to that statement, Abelard later wrote, in his Historica, Nor in this, as now the whole world knows, did she lack the spirit of prophecy. Secretly married, the couple left Astrolabe with Abelards sister. When Heloise went to stay with the nuns at Argenteuil, her uncle and kinsmen believe Abelard had cast her off, forcing her to become a nun. Fulbert responded by ordering men to castrate him. Abelard wrote about the attack: Violently incensed, they laid a plot against me, and one night while I all unsuspecting was asleep in a secret room in my lodgings, they broke in with the help of one of my servants whom they had bribed. There they had vengeance on me with a most cruel and most shameful punishment, such as astounded the whole world; for they cut off those parts of my body with which I had done that which was the cause of their sorrow. The Legacy of Abelard and Heloise Following the castration, Abelard became a monk and persuaded Heloise to become a nun, which she didnt want to do. They began to correspond, leaving what is known as the four Personal Letters and the three Letters of Direction. The legacy of those letters remains a great topic of discussion among literary scholars. While the two wrote of their love for each other, their relationship was decidedly complicated. Furthermore, Heloise wrote of her dislike of marriage, going so far as to call it prostitution. Many academics refer to her writings as one of the earliest contributions to feminist philosophies.

The And Flow Of Ideas About God And Religion Throughout...

The ebb and flow of ideas about God and religion throughout the life of Marjane Satrapi, the author of the autobiographical novel Persepolis, is made very clear in her novel. As she is introduced to new thoughts and experiences, her ideas change. When her parents expose her to their communist ideas begins to value her relationship with god less. When things return back to normal she returns. It is not until a series of fairly traumatic events that she drifts completely away. Satrapi uses Illustrations of her and God as a metaphor for her current relationship with God. Later she uses her actions and words to depict this relationship. At the beginning of the book, Satrapi is very religious, but as she is gradually exposed to more and more western, secular, ideas, her relationship with God begins to disintegrate. This is apparent in how she depicts herself and God. In the beginning, Marjane begins by saying that she wanted to be a prophet and her relationship with God is good; She is in gods arms and they talk to each other. Satrapi uses this imagery as a metaphor for Marjane’s closeness with God. She begins to ignore god after she has started to read western, secular, ideas.(Satrapi 14) After that, God does not come to her. This is a new experience for her. In the beginning of the book, Marjane is told at school that the Shah was chosen by God, and she then relays this information to her dad (Satrapi 19). Until this point, no one has told her how the Shah was chosen. So,

Mindfulness Stress Reduction and Change In Health Related Behaviors

Questions: 1.Mindfulness Based Stress Reduction and Change In Health Related Behaviors- Salmoirago-Blotcher et al? 2.What is the clinical significance of chest CT when the chest x-ray result is normal in patients with blunt trauma? - Kea et al? Answers: 1.The following write up contains my reflection of a published paper that I have read. This will involve reflecting on the research design adopted by the research article and my opinion on it appropriateness. I will also include either how the research would be expanded to take a more pragmatic post positivist appropriate or how the study design would have been improved. The research paper topic was mindfulness Based Stress Reduction and Change in Health Related behaviors. The paper was authored by Elena Salmoirago- Blotcher, Daniel Fischer, Matthew Hunsinger, James Carmody and Lucas Morgan. The research paper used was published in 2013 on Journal of Evidence Based Complementary and Alternative. The study aimed to investigate if mindfulness training is correlated by health behaviors. This study was inspired on how health behaviors can be used to address public health. The study outlines unhealthy behaviors to be poor diets, smoking, and physical inactivity. These unhealthy related behaviors contribute to health disorders such as metabolic syndrome, cardiovascular disease, type 2 diabetes and obesity (Tielsch-Goddard and Ridner, 2016). Therefore, the study seeks to use mindfulness training to change health related behaviors to promote sustainable behavior change to solve the public health problem of chronic diseases. The Mindfulness Based Stress Reduction and Change in Health Related Behavior study adopted explanatory research design. The study design was used in order to show casual relationship between mindfulness activities and health of an individual. The study design uses a mindfulness based stress reduction program to show and explain how change in health behaviors can lead to health public health improvement. The research involves the study of unhealthy behavior and their change to prevent chronic diseases. The explanatory research design used by the Authors of the study led to stating of the study hypothesis. The study hypothesizes that public health can be improved through change of health related behaviors. The study also hypothesis that mindfulness based stress reduction program can be used to change and promote sustainable healthy behaviors (Flannelly, Jankowski, 2014). Secondly, the explanatory research designs necessitated the use of qualitative data. The qualitative data is collected on individuals dietary behaviors, quality of sleep, drinking, physical activities, and smoking. The mindfulness program that individuals attend is conducted for seven weeks. The data on the health related behavior is collected on the beginning and end of the eighth week. The study used a population of 174 participates with 61% being female and 39male. The range of the population was 19-68. The data was collected by use of questionnaires and interviews. Lastly, the data for the explanatory research design was analyze by use of T-test data that was paired and chi-square was used to comparing pre-post intervention means. The study research design was appropriate to establishing a structure that was used to meet the study objective. The explanatory research design was appropriate for establishing the correlation of mindfulness and health of an individual. The Pragmatic past positivist approach to be incorporated in the design used in this study could be health check up in the beginning and at the end of the eighth week. This pragmatic measure would have collected data on the health of the participants at the beginning and improvement at the end. 2.I looked at descriptive statistics of What is the clinical significance of chest CT when the chest X-ray result is normal in patients with blunt trauma? article. The article was published on American Journal of Emergency Medicine. The study had an objective of investigating the portion of patients that have normal chest x-ray (CXR) injury and results seen on CT and abnormal initial CXR and no injury on CT and then characterizes the clinical significance of the injury. The CT was determined by the trauma experts. The study used 3639 participants where 2848(78.3%) had CXR and 791(21.7%) had both were CT and CXR done. Out of 589 individuals who chest CT test after undertaking CXR of which 82% (95% confidence interval, 78.7-84.9%) were normal Ct results while 18%(95% confidence interval, 15.1%-21%) had injuries. From the study of the descriptive statics of this article, I was able to understand the percentages used to interpret and analyze the data collected. The percentage used in the research refers to the distribution of the cases in the data. For instance 82% means the study found occurrence to variable having a mean of 82. This entails that out of a hundred sample of the population, the variable is present in 82 samples. The descriptive data also should a variability of the data. For instance 82% with variability of 78.7%-84.9% means that standard deviation of the distribution is between 78.7% and 84% for the data (Speroff and O?Connor, 2004). Lastly, I was able to understand the confidence interval applied in the study of 95%. It means that it true that the mean gotten in the research done are 95% correct and 5% not correct. From the weekly studies on basic interpretation of central tendencies and variability or spread, I have been able to acquire knowledge to understand, define, describe, identify, compare, and interpret descriptive statistic used in research papers.

Tay Sachs Research Paper Essay Research Paper free essay sample

Tay Sachs Research Paper Essay, Research Paper Introduction There are many familial diseases in the universe. All familial diseases are inherited from one # 8217 ; s parents. Through Gregor Mendel # 8217 ; s surveies of genetic sciences, it is possible for people to find whether or non an person will inherit a familial disease. All familial upsets are recessionary traits ( Campbell ) . We will write a custom essay sample on Tay Sachs Research Paper Essay Research Paper or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page We have learned that if a parent has a familial disease and the other parent does non hold a familial disease, all of their kids will be bearers, or have the trait, of the disease. If both parents are bearers of a familial disease, one out of the four kids will acquire the disease. Some of the most common familial upsets today are sickle cell anaemia, muscular dystrophy, cystic fibrosis, haemophilia, and Tay-Sachs disease. Most of the diseases normally is prevailing in a race of people or in gender ( Campbell ) . Today through modern engineering, we are able to observe whether a kid will hold a familial disease through the methods of amniocentesis and chorionic Villa sample ( Campbell ) . One of the familial upsets that doesn # 8217 ; t have a batch of attending is Tay-Sachs disease. Tay-Sachs can be really deadly. Discussion What is Tay-Sachs Disease? Tay-Sachs Disease is a birth defect caused by a dysfunctional enzyme that fails to breakdown group of encephalon lipoids, or fat ( Campbell ) . The cause of the dysfunctional enzyme is caused by a lack of an enzyme called Hexosominidase A, or Hex A which is suppose to interrupt down fatty substances in the nervus cells of the encephalon. When the lipoids, or fats, builds up in the encephalons nerve cells, it leads to a slow devolution of the cells of the nervous system, therefore conveying decay of the cerebellum. This impairment can be view on Magnetic Resonance Imaging ( MRI ) ( webknx.com ) . The fatty substance that Hex A does non interrupt down is called ganglioside GM2. Ganglioside GM2 accumulates on the encephalon cells and can non be broken down. Gangliosides are made and bio-degraded rapidly in the early development of the encephalon ( www.ninds.nih ) . When Hex A activity is deficient, accretion of ganglioside GM2 in the nerve cells affects the operation of the nervous syst em. How is Tay-Sachs Transmitted? Tay-Sachs disease, unlike other diseases, is transmitted by a individual # 8217 ; s familial brand up. Tay- Sachs can merely be transmitted if a individual has both recessionary allelomorphs for the trait ( Campbell ) . In order for a kid to acquire Tay-Sachs his or her parents must be bearers of the Tay-Sachs cistron. Tay-Sachs bearers are non afflicted with Tay-Sachs. They can populate normal and heathy lives ( www.noah ) . If at least one parent is a bearer of the disease, two out of four off the progeny will be a bearer of the disease. If both parents are bearers of the disease, one out of four kids will non be a bearer, two out of four of the kids will be a bearers of the disease, and on out of four of the kids will really hold the Tay-Sachs disease ( www.webknx ) . Figure 1 ( www.mrcr2 ) is a tabular array that shows how two carries for Tay-Sachs disease can go through either Tay-Sachs trait or Tay-Sachs Disease to their kids. Figure 1 Who Gets Tay-Sachs Disease? Tay-Sachs Disease is common among people of Eastern Europeans ( Ashkenazi ) Jewish decent, Cajun, and French-Canadian decent ( www.noah ) . Although some people of French-Canadian and Cajun ancestry acquire Tay-Sachs, the disease is preponderantly found among Ashkenazi Jews. In the United States, about one out of 60 thousand people who have the Tay-Sachs disease are in the Judaic population while one out of 14 thousand are afflicted with Tay-Sachs in Israel About one out of 30 Jews in America bearers the Tay-Sachs disease trait ( www.webknx ) . Are at that place Different Forms of the Tay-Sachs disease? There are different signifiers of Tay-Sachs. There is the common childish Tay-Sachs, normally called juvenile Tay-Sachs. In childish Tay-Sachs the enzyme Hex A is non present to interrupt down lipoids in the encephalon cells. The other signifier of Tay-Sachs is the grownup oncoming of Tay-Sachs. Adult onset of Tay-Sachs differs from childish Tay-Sachs because there are low degrees of Hex A enzyme in the encephalon cells. But like childish Tay-Sachs, grownup oncoming of Tay-Sachs still do impairment of the encephalon cells. In childish Tay-Sachs, the kid affected normally dies around the 5th twelvemonth of their lives. Peoples with big onset Tay-Sachs normally die around their 15th birthday ( www.noah ) . What Are the Symptoms of Tay-Sachs Disease? Symptoms of Tay-Sachs Disease can be painful and hard to cover with. Most of the symptoms of Tay-Sachs are physical symptoms. These symptoms can dwell of manus shudders, awkwardness, address hindrances, get downing troubles, jobs with pace and balance, and musculus failing. Other jobs with Tay-Sachs included temper changes, unnatural behaviour, Muscular Dystrophy, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis. Not all symptoms of Tay-Sachs are physical ( www.webknx ) . Most patient with Tay-Sachs develop mental unwellness and suffer from psychological jobs. Psychological symptoms of Tay-Sachs are memory damage, trouble in comprehension accomplishments, and hapless public presentation in school. Loss of memory is really common among Tay-Sachs patients ( www.webknx1 ) . Babies who inherit the Tay-Sachs Disease normally have a shut down of their nervous system. First marks of a infant holding Tay-Sachs diseases are bit by bit loss of smiling, creeping, turning over, loss of abil ity to hold on objects, sightlessness, palsy, and unknowingness of milieus ( www.noah ) . How Can a Person Find Out if They Are a Carrier of Tay-Sachs Disease? A individual can happen out whether or non they a rhenium bearer of the Tay-Sachs Disease by seeing a geneticist. The geneticist would take sample of a person’s Deoxyribonucleic acid and analyse it for the enzymes hexosaminidase A and hexosaminidase B. The geneticist would so look for mutants in the two enzymes. If a mutant is found, the individual is perchance a bearer for Tay-Sachs Disease ( Triggs- Raine ) . How Can One Find Out if Their Child would Have or Be a Carrier of The Tay-Sachs Disease? If an expectant female parent wants to cognize if her kid will hold Tay-Sachs or be a bearer of the disease, she would travel see her obstetrician for familial showing. The obstetrician will either execute an amniocentesis or chorionic villus sampling, or CVS ( Campbell and www.noah ) . In amniocentesis, which is normally done between the fifteenth and 18th hebdomad of gestation, a acerate leaf is inserted into the female parent # 8217 ; s venters to take sample of the amniotic sac fluid that surrounds the foetus. The fluid contains foetal cells that can be examined for the presence of the enzyme hex A. In CVS, which is normally done during the ten percent to twelfth hebdomad of gestation, the physician would take samples of cells either through a thin tubing inserted through the vagina and neck to the placenta or by infixing a long acerate leaf through the female parent # 8217 ; s tummy. Like the amnionic fluid, the placenta cells contain hex A ( www.noah ) . Amniocentesis is done by centrifugating the amnionic fluid, salvaging the pellet for a civilization to be karyotyped. This method is clip devouring whereas with CVS the consequences of the karyotyping can be revealed within twenty four hours ( Campbell ) . Are there Any Recent Scientific Studies on Tay-Sachs Disease? Although Tay-Sachs Disease is non reference every bit much as other familial upsets, such as reaping hook cell anaemia, there is recent research being done on Tay-Sachs. There was a trial done to test bearer of the Tay-Sachs disease. The trial consisted of a comparing of DNA-based and enzyme-based trials. In the trials, scientist looked for the substance ganglioside GM2 in each of it # 8217 ; s topics. They so compared the enzyme-based trial with the Deoxyribonucleic acid based trial. After comparing the analysis of both trials, the scientists concluded that there were three mutants of Tay-Sachs Disease. Two of the mutants cause childish Tay-Sachs and the 3rd was big oncoming of Tay-Sachs. The mutant of Tay-Sachs were found on the DNA polymerase ironss ( Triggs- Raine ) . The DNA- and enzyme-based trials were performed on about 62 Ashkenazi Jews who carried the cistron for Tay-Sachs. The study didn # 8217 ; t province whether the people being tested really had Tay-Sachs or if they merely carried the cistron for Tay-Sachs. Ninety per centum of the people tested had all three of the mutant strands of Tay-Sachs Disease. The DNA-based trial proved to demo whether a individual carried the three of the mutants Tay-Sachs Disease better than the enzyme-based trial ( Triggs-Raine ) . Decision Tay-Sachs Disease is a familial upset that can non be corrected, at least non in this present clip. Although there are now ways for a individual to hold familial showing to see if they have Tay- Sachs or if they are a bearer of Tay-Sachs, they still have to populate with the possibility that they might go through on the familial upset to their kids. It possibly a one out of four opportunity that a twosome who both have the Tay-Sachs bearer cistron might hold a kid with Tay-Sachs, but that is a hazardous opportunity to do. Possibly with future engineering, scientist would be able to happen a manner to change by reversal the mutants of the Tay-Sachs Disease cistron.

Terrain essays

Terrain essays Advantageous terrain was perhaps the most important factor in the Civil War battles. There are an incredible amount of factors involved in winning a battle which all revolve around the terrain and the position of the units in that terrain. Terrain can effect such things as troop morale, ease of command and strategic placement, profitable early views of the enemy troops, and of course methods of shielding. It has been proven many times throughout history that terrain can be the winning factor in a battle, even in cases where the winner was extremely outnumbered. One of the best utilizations of advantageous terrain, displayed especially during the Civil War, was having the high ground. The high ground enabled the soldiers to dig in and fortify a position with great efficiency. This came in handy especially if the soldiers on high ground were defending, but it also helped immensely when attacking. When defending, a soldier could easily set himself behind a tree or obstacle of some sort and act as a sniper. Longstreet explains it very well in The Killer Angels. He explains, Just put one man behind a tree. You can hardly see him from two hundred yards away, but he can see you. And shoot. And shoot again.
