Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

NUCLEAR REACTORS A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas)‚ which runs through turbines. These either drive a ship’s propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are

In spring of 1989‚ two scientists by the name of Stanley Pons and Martin Fleischmann announced that they had found a way to create nuclear fusion in a relatively simple and cheap way. Superhot fusion is the process in which deuterium‚ a heavier form of hydrogen‚ is held within a magnetic field and heated to tens of millions of degrees. The nuclei of the atoms fuse‚ and heat energy is released. This kind of fusion happens in our solar system’s sun. This type of fusion is known to occur‚ but recreating

Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest

What happens when you take two natural wondering parallel lines and force them to turn whilst still parallel? In a two dimensional perspective you will see two overlapping waves with a positive and negative parabola opposite from one another. In reality we would see a spiral. Imagine that these lines are instead two of the smallest forms of energy known as a photon and they are spiraling each other. When you reach distances of four hundred nanometres to seven hundred nanometres in between the photons

Opportunity cost The true cost of something is what you give up to get it.(This includes not only the money spent in buying (or doing) the something‚ but also the economic benefits (UTILITY) that you did without because you bought (or did) that particular something and thus can no longer buy (or do) something else.) Factors of production The ingredients of economic activity: land‚ labor‚ capital and enterprise. Economic Development The scope of economic development includes the process and
