could help the country firmly establish itself on the global science and technology map. Going by the report of industry and research bodies‚ the sector holds immense potential for India’s economy. GLOBAL BIOTECH DEVELOPMENT – INDIA’S ROLE: Given India’s share at only 2% in the global biotech market‚ her role in the field of biotechnology has till now been a supplementary one. The country has trained and supplied high quality human resources and scientists for U.S universities and

Atomic nuclei consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the

12. Outline the symbol’s box in dark green if it is RADIOACTIVE in its most common form. Notes The nucleus The nucleus is at the center of the atom and contains the protons and neutrons. Protons and neutrons are collectively known as nucleons. Virtually all the mass of the atom is concentrated in the nucleus‚ because the electrons weigh so little. Working out the numbers of protons and neutrons No of protons = ATOMIC NUMBER of the atom The atomic number is also given the more descriptive

SCI215 M4-Assignment 1: Discussion—The Promises and Perils of Nuclear Power Nuclear power refers to the generation of electrical energy by controlled nuclear reactions. These reactions produce heat‚ which in turn creates steam that runs the generators to produce electricity. Approx. 1/8 of the electricity worldwide generated comes from nuclear energy. In this task‚ you will analyze the use of nuclear energy as a resource energy. * Discuss the scientific and technical concepts related to

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

the question remains whether these mathematical manipulations actually correspond to the spatial deformations in real nuclei. Problems with the shell model have led some to propose realistic two-body and three-body nuclear force effects involving nucleon clusters and then build the nucleus on this basis. Two such cluster models are the Close-Packed Spheron Model of Linus Pauling and the 2D Ising Model of MacGregor.[10] Consistency between models[edit] Main article: Nuclear structure[->0] As with

Corporate Power in Seeds‚ Agrochemicals & Biotech By Hope Shand Sixteen years after GE crops made their commercial debut in the US‚ what are the benefits for farmers‚ diversity and society? The following article‚ adapted‚ in part‚ from ETC Group’s Who Will Control the Green Economy?‚ provides an update on current trends in industrial agriculture and examines the giant firms that control “the first link” in the corporate food chain.1 The Big Six Seed‚ Biotech & Agrochemical Corporations Business-friendly

Island In the film ‘The Island’‚ directed by Michael Bay there are many scenes which include various techniques to show a theme. In this scene Lincoln Six-Echo and Jordan two-Delta decide to go back to Dr Merricks Biotech facility and attempt to save their clone friends and destroy the biotech facility. Their moral and compassionate actions allow them to do this and in doing so risk their freedom and lives. In the end it’s their actions that make us understand the system was not right.
