Use Of A Traumatic Brain Injury - 1117 Words

TBI termed as Traumatic Brain Injury is an intracranial injury that often occurs when an external force is applied on the brain. A 1.4 million people, every year in the United States experience TBI, as reported by the Centers for Disease Control and Prevention (CDC) [2]. Approximately 5.3 million Americans live with long-term disability as a result of TBI [4]. Advancements in the field of Magnetic Resonance Imaging (MRI) has helped image TBI better. Techniques like Susceptibility Weighted Imaging (SWI), Diffusion Tensor Imaging (DTI), and Magnetic Resonance Spectroscopy (MRS) helps in furnishing sensitive details like micro hemorrhages, white matter injury, and abnormal metabolic activities, respectively, in brain injury. In order to†¦show more content†¦A Computed Tomography (CT) can be used to inspect large hemorrhages, that could be surgically excised, but in case of small hemorrhages, it is insensitive. Small hemorrhages could be early contusions or diffuse axon injury ( DAI). SWI comes handy in determining such small hemorrhages and intracranial microhemmorhages. It is a high-resolution, fully velocity compensated, 3-dimensional gradient echo imaging sequence that is extremely sensitive to blood products in hemorrhage and deoxyhemoglobin in venous blood. Normally, CT and MRI would spot traumatic hemorrhagic lesions in cortical gray matter (GM), sub cortical white matter (WM), major white matter tracts, including corpus callosum and internal capsule, brainstem and in the ventricles. SWI helps in localizing microhemmorhages lesions at GM/WM junction. The research paper explores about a comparison of SWI and a conventional GRE performed by Tong et al. The outcome of it was a difference in lesion counts, which was highest in the brainstem/cerebellum and corpus callosum, while, lowest in the frontal parietal-temporal-occipital GM/WM. The research article also reviews a study by Wu et al about patients with subarachnoid hemorrhage (SAH) using CT and SWI . The

Adolf Hitler and the Holocaust Essay - 1114 Words

Germany’s fate was changed on April 20, 1889, the day I, Adolf Hitler was born to German official, Alois and my dear, Klara Hitler. Little did they know of what a miracle that had blessed them that day. My destiny was decided for me every time my father lectured me about the abhor Jews, taking up our German property, and beat me for the childish mistakes I made. I realized my destiny was to punish the faults in our once perfect nation. My father’s strict upper hand was not the only contribution to my great plan.

In 1933, after years of working with the members of the Nazi party, I climbed my way up the ladder to success, and became an official leader of Germany. As so on as I came into power, ghettos were placed around Germany to house the Jews and their disgusting lives away from society. The ghettos soon became overpopulated, everywhere you looked, scrawny, dead Jews lay. So, to dispose of the weak, sick, old, or rebellious, concentration camps were placed all over Germany. There, we disposed of the Jews in an efficient way, cremation. Using this system, we executed millions of Jews. C. The first time I walked through the streets of Warsaw, the most populated ghetto, housing over four hundred thousand Jews was June 1, 1937. From over the ghetto’s fence, the smell of retched death seeped over. Every man with me pinched their faces in disgust. An officer walked over to greet us at our station wagon. The excitement in his eyes of meeting greeting me was admiring. He reached his hand out and nervously stated, â€Å"I can’t believe I am meeting the one and only Adolf Hitler. How do you do, Sir? Sargent? General?† I shot my hand out confidently, and shook his hand, â€Å"Good Day, officer. I have finally gotten the time to visit Warsaw, my apologies for waiting so long.

Ernst Mach vs. Bertrand Russell Free Essays

The purpose of this paper is to show that while Ernst Mach and Bertrand Russell share similar views on matter and knowledge, their end conclusions differ. Mach believes humans think in an economical manner where past experiences and knowledge are systematically reorganized to fit a pattern (Mach 211). Rather than analysing each experience in detail, humans refer to similar or related experiences as groups, which allows for the â€Å"least expenditure of thought† (Mach 197). We will write a custom essay sample on Ernst Mach vs. Bertrand Russell or any similar topic only for you Order Now In line with this mentality springs the concept of ‘things’ and ‘bodies’. Mach states that colours, sounds, temperatures, etc. re called sensations (Mach 208-209). When certain sensations are present repeatedly, they would fit into a pattern. To allow for future reference on this knowledge within the mind, the pattern receives a label. An example would be when a person sees an orange, bouncy, sphere object which has a mildly rough texture, the label ‘basketball’ springs to mind. The ‘basketball’ would not be a physical object; it would simply be a â€Å"mental symbol† for the sensations and Mach states that â€Å"symbols do not exist outside of thought† (Mach 201). Russell believes that certain things, such as a table or a cat, consist of sense-data hich are colours, sounds, smells, etc. and that the immediate awareness of such things is known as a sensation (Russell 12). Also, the existence of an object is not nece ssarily associated with the sense-data as different people receive different sense-data when they are under the belief that they are viewing the same object (Russell 20). In addition, a person would only know the certainty of perceived sense-data rather than of the object since sense-data depends on the perception and relation of the object to the perceiver (Russell 16). Russell then states that although there is no proof of a physical world, the belief that there are objects corresponding to sense-data allows for the simplification people’s experiences. Therefore, believing in an external world is easier than thinking otherwise. Both Mach and Russell believe in the perception of colours, sounds, etc. but they label them differently; Mach calls them sensations and Russell calls them sense-data. Also, neither doubts the existence of these perceptions as they reside within the mind. Mach does not call into question the experience of sensations and Russell states that there is no doubt for the existence of sense-data (Russell 18). This indicates that both believe in physical causes that create such perceptions, but not necessarily believe in the existence of physical objects. In addition, both regard human knowledge to be built up from instinctive beliefs and the economic categorization of these beliefs form the basis of science and an organization of information (Mach 191; Russell 25). The two philosophers differ in views when regarding the existence of the physical world. Mach states that the idea of substance is a â€Å"crude notion† and that â€Å"bodies or things† do not exist in the external world (Mach 201, 203). In contrast, Russell asserts that it is instinctive belief to believe in an â€Å"independent external world† and since this belief â€Å"does not lead to any difficulties†, there is no reason to reject the belief (Russell 24). Mach’s overall view seems more sceptical relative to Russell since, even though he mentions that humans can easily believe that things other than sensations exist outside of thought, with no proof, he considers objects to be merely labels which only reside within the mind. This may be due to the reasoning that solid justification should support a notion for it to be a valid belief. Mach regards science in a negative light as he states it uses â€Å"lavish extravagance† and comments that, in the form of personification that â€Å"she needs [no] justification of her aims† (Mach 189). Russell, on the other hand, seems to believe that questioning the existence of the physical world and objects within it to be a difficult task and in turn states that believing such a simple, systematic notion of an external world would be a better solution. When he cites Descartes’ systematic method of doubt to be an attempt to deny the existence of everything but oneself, he inquires on the firmness of the theory in regards to â€Å"‘I think, therefore I am’â€Å"(Russell 19). By addressing a strong theory that questions the existence of everything, then indicating the flaws within the theory, Russell demonstrates the difficulty in creating a sound theory which denies the physical world. Almost similar in Descartes’ perspective in the belief of the existence of an Evil Genius, Russell takes the position that if there is no proof denying the existence of a physical world then the possibility of it allows for belief in physical objects and an external world (Russell 24-25). In conclusion, Mach and Russell have similarities in their theories, but their overall views greatly differ. Mach and Russell’s view on perceptions such as colour, sound, etc. are similar, although each has different labels for the ideas: sensations and sense-data, respectively. In addition, both believe in the simplicity or economy of knowledge. The philosophers then differ in the belief of an external world, where Mach denies the existence of physical objects, where Russell believes in such a notion. Russell’s acceptance of an external world seems more in line with the economical nature of knowledge as understanding the idea of an external world is easier and allows for better explanations for perceptions of colour, sound, etc. Both philosophers have sound theories but neither has evidence where anything is absolutely certain and as such the study of philosophy continues to address doubts which revolve around our reality.
