About the Cover

Newton, Sir Isaac (1642-1727) is a mathematician and physicist. He is one of the foremost scientific intellects of all time. He Born at Woolsthorpe, near Grantham in Lincolnshire. He was elected as a Fellow of Trinity College in 1667 and Lucasian Professor of Mathematics in 1669. In 1671, he was elected as a Fellow of Royal Society of London, and in 1703 he became President. Newton became the most highly esteemed natural philosopher in Europe. Newton was modest, diffident, and a man of simple tastes. He was angered by criticism or opposition, and harboured resentment; he was harsh towards enemies but generous to friends. In government, and at the Royal Society, he proved an able administrator. He never married and lived modestly, but was buried with great pomp in Westminster Abbey. He discovered measurable, mathematical patterns in the phenomenon of color. He explained the workings of the universe through mathematics and he formulated the laws of motion and gravitation. He used three laws to explain the way objects move. They are often called us Newton’s Laws. The First Law states that an object that is not being pushed or pulled by some force will stay still, or will keep moving in a straight line at a steady speed. The Second Law explains how a force acts on an object. An object accelerates in the direction the force is moving it. The Third Law states that if an object is pushed or pulled, it will push or pull equally in the opposite direction.

DISCOVERY OF THE MONTH

Review and report on HAM test

Balasubramanian J, Narayanan N, Azhageshraj K, Pragadeesh K

The Ham’s test is done to diagnose paroxysmal nocturnal hemoglobinuria (PNH). The test checks whether red blood cells become more fragile when they are placed in mild acid. It can also be used to diagnose another rare disorder called congenital dyserythropoietic anaemia. Paroxysmal nocturnal hemoglobinuria (PNH), is an rare acquired stem cell disorder associated with periodic hemolytic events. This benign clonal disease is caused by abnormalities of the Xlinked phosphatidylinositol glycan class A (PIGA) gene and is associated with cytopenias and thrombosis.

RESEARCH

A Direct cost savings analysis of a gasoline-electric vehicle

Kwasi-Effah CC, Obanor AI

Generally, vehicles ability to reduce emissions is particularly important as they contribute to environmental pollution which threatens public health and welfare. Hybrid vehicles are seen as one of the major solutions in reducing the consumption of gasoline and emissions of greenhouse gases. Besides the reduction of green house gases, hybrid vehicles contribute significantly to the reduction of the operating cost of the user. So far, different approaches have been used to evaluate the cost benefit of hybrid vehicles. In this paper, a direct method involving combined simulated high way fuel economy test (HWFET) and urban dynamometer driving schedule (UDDS) drive cycle data and analysis was used to evaluate the life cycle cost of a series-parallel gasoline-electric vehicle based on the energy consumption of the model.
