Australia should definitely produce nuclear technology. Throughout this point in time, Australia is one of the few developed countries not using nuclear technology and energy. Nuclear has been used for over 50 years and supplies nuclear power to over 32 countries, without producing signs of any emissions. Therefore, Australia should develop nuclear technology as the geology of Australia is perfectly stable for the production of nuclear technology and more importantly, we have abundant uranium…

Organ transplants save thousands of lives each year and are considered one of the most significant medical innovations of the past century. Despite that, each year, the number of patients on the waiting list continues to grow, while the number of donors and transplants remains stagnant. One solution scientists are investigating in order to solve this problem is xenotransplantation, a procedure which involves the “transplantation, implantation, or infusion of live cells, tissues, or organs from a…

Write an essay on the structure of proteins, emphasising the forces that sustain their three dimensional structures. Introduction MORE Proteins are nitrogenous organic macromolecules constructed from a base sequence of 20 amino acids at the ribosome in cells. There are over 100,000 different proteins encoded by thousands of different genes within the human body. They all perform different functions e.g. antibodies providing immunity and enzymes catalysing metabolic reactions. The…

The low-density lipoprotein (LDL) receptor is an important protein in human function. LDL receptor is the main protein that binds and carries cholesterol to maintain homeostasis in mammalian cells. In human plasma, it is also the most abundant cholesterol-carrying lipoprotein (Goldstein and Brown, 1987). It plays a major role in the development of atherosclerosis, a chronic disease caused by the accumulation of LDL-cholesterol in the blood. The LDL receptor is also the main protein that is…

Aspiration is inhalation of foreign material below the vocal cords. In anesthesia practice, the inhalation of gastric content is rare 1 per 2000-3000 cases occurrence, however the consequences of the complication can be detrimental (Raghavendran, Nemzek, Napolitano, Knight, 2011). Presentation of the pulmonary aspiration ranges from silent aspiration, where the patient does not experience any symptoms, to the development of acute lung injury (ALI). The mortality rate after development of ALI…

Radioisotopes are atoms that consist of unstable combination of neutrons and protons. All elements which have their atomic numbers greater than 83 are radioisotopes and have unstable, radioactive nuclei. They have at least one stable isotope and one unstable isotope. In order to gain stable conformation the nucleus of the atoms loses a neutron due to which radiation energy is given off and the atom is said to be in radioactive state. They are also called as radionuclides because they have more…

The effect of temperature on the rate of reaction on Enzyme reaction Introduction: This experiment will investigate the effect of temperature on the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically.…

Abstract: NASA is one of the biggest Space programs in the world, and lead most space missions and discoveries. Recently they have intensified their research about water on Mars, as they are looking to find the presence of life on a new planet. Many discoveries have been made allowing them to strongly believe that Mars contains water and might still contain it. They still need to do a lot of research to confirm their interpretations and research as some of their arguments can be explained by…

example; Viruses, Bacteria and Fungi. Not all infections are the same; some are mild while some can end up being life threatening. Also, infections can be contagious; they can be transmitted by a variety of ways, for example; skin contact, airborne particles, touching an object that an infected person has touched. One of the very common and effective ways to prevent infections is by vaccinations. A vaccine is a prepared substance that consists of an imitation of a certain pathogen in order to…

Radiation Therapy What is Radiation Therapy? Radiation therapy is one of the most common, innovative and successful forms of cancer treatments of the modern world. It can successfully treat and cure approximately 50 unique forms of cancer1, utilizing alpha, beta and gamma radiation to destroy or damage cancer cells2. This helps prevent the rapid multiplication of the destructive cells, with minimal impact upon the somatic cells surrounding the cancerous area, and treats both primary, and…
