Research proposal ( Role of M.R.I spectroscopy in differentiation Essay

Research proposal ( Role of M.R.I spectroscopy in differentiation between the Malignant and the benign tumours ) - Essay Example In MRI Spectroscopy, water protons are utilized in creating images, and for producing images of the brain that are detailed and sophisticated. This is because various brain tissues contain varying amounts of water. Non-aqueous protons, which consist of the hydrogen nuclei protons which are not in water are scattered throughout the biologically significant brain molecules. The significant signals from these molecules are invisible when attempted to be viewed otherwise, due to the fact that they are overshadowed by the greater signals of the aqueous protons. Each non-aqueous molecule possesses a unique radio-frequency that is specific to that particular chemical, and which is different from the water proton frequency. The strength or amplitude attained by these radio-frequencies depends on the concentration of the molecules inside the volume in question, and each of them has its own discrete position of frequency. Thus, a graph can be displayed showing the relative amplitude peaks for various biological molecules, and these peaks of amplitude can be detected and displayed more easily if the signals generated by the aqueous protons are suppressed. MRI Spectroscopy uses an imaging technology that is non-invasive, and which records information as regards the chemical makeup of human tissue without any need for biopsy or surgery. The aim of this research is to ascertain the role of MRI Spectroscopy in the diagnosis of cancerous (malignant) tumors in contrast to benign and healthy growths that are non-cancerous, based on chemical information. â€Å"Although the spectral features of prostate tissue markedly change after radiotherapy, MRI Spectroscopy combined with multivariate methods of analysis can accurately identify histologically malignant biopsies. MRI Spectroscopy shows promise as a modality that could integrate three-dimensional measures of tumor response.† (Michael D. Kuo, 2006) This research on The Role of M.R.I spectroscopy in

Science Education and Public Understanding Essay

Science Education and Public Understanding - Essay Example According to the report findings in Colloquial Use, Law in Science are a simple generalisation about how certain things in this natural world behave under certain conditions. In addition, the term is used to denote an existing experimental relationship between two or more parameters. In this case, it can be explained that Laws are commonly created after a lot of study and experiments have been conducted and hence a connected between two scientific quantities established. A good example of scientific the Laws include the thermodynamics, which explains the relationship between a given quantity of heat and the amount of kinetic energy that can be produced. In this case, the law shows how a quantity behaves rather than giving the explanation on why it behaves certain way. Another illustration of a scientific law is the famous Newton's  Law of Gravity. The law gives a prediction on the behaviour of an objected when dropped from a certain height. However, the law does not give an explana tion on why the object behaves in that particular manner.This essay declares that  a hypothesis is a critical part to a theory. This is because the hypothesis predicts the outcome of a theory that will either be proven to be authentic or void. It is created when it has survived all challenges of falsifying the theory. Most scientists show demonstrate a large number of experiments that are enough for them to only give details of all the tests that it carries out.
