a locomotive. This system tries to harvest energy which is otherwise wasted. KERS works on the principle of Regenerative Braking‚ which uses the braking energy to rotate a flywheel connected to the differential( in an automobile) through a gear mechanism‚ which when actuated( while braking )uses the energy to spin the flywheel at more than 60‚000 rpm. There are various methods of achieving this‚ most commonly used systems are Electrical KERS and Mechanical KERS. Electrical KERS uses a generator and

One of the mechanisms by which these ideologies are perpetuated is the Sorting and the Sorting Hat. At the beginning of a student’s journey at Hogwarts‚ the Sorting Hat sorts and depicts each student into a house. Before beginning the Sortings‚ the hat sings a song to acquaint those being sorted with what to expect. "There’s nothing hidden in your head’ it sings in Sorcerer’s Stone‚ "The Sorting Hat can’t see‚ / So try me on and I will tell you / Where you ought to be." (117-118). This song‚ creates

Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

1. Type of basic mechanisms for exchange rates a). Free float Free floating or clean float is a type of country’s exchange rate regime where a currency’s value is allowed to fluctuate according to the foreign exchange market. Free floating exchange rate is determined by the interaction of currency supplies and demands with no government intervention. It always termed “self- correcting’ as if any differences in supply and demand‚ the exchange rate will automatically be corrected in the market

Stress and Coping Theories H. W. Krohnea a Johannes Gutenberg-Universität Mainz Germany Available online 2002. Abstract This article first presents two theories representing distinct approaches to the field of stress research: Selye ’s theory of `systemic stress ’ based in physiology and psychobiology‚ and the `psychological stress ’ model developed by Lazarus. In the second part‚ the concept of coping is described. Coping theories may be classified according to two independent parameters:

The different cell membrane transport mechanisms The cell membrane is referred to as a ‘fluid mosaic model’ because the protein part within the cell membrane used to be though of as an even layer spread over the outside and the inside of the phospholipid. Now we are starting to think that it is spread unevenly‚ more like a mosaic than a layer. The phospholipid part of the cell membrane is fluid; this means that its molecules are constantly moving about. Through the molecules constantly moving
