Most people usually traveled by ship and train which are driven by steam engine. It played an important part in many kinds of vehicles several scores of years ago. Who invented steam engine and what units could be used to measure the power of engine?

The word “horse-power” was first used two hundred years ago. James Watt from a worker‟s family made the world first widely used steam engine. At first, he couldn't tell people how powerful it was, because there were no units at that time. Watt decided to find out how much work one strong horse could do in one minute. He named that unit one horse-power. In this way he could measure the work of his steam engine.

He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute. His engine could lift a 3300-pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten horse-power engine.

The search for latent prints is done in a systematic and intelligent manner. Investigators develop techniques to locate traces of fingerprints at a crime scene. The basic premise in searching for latent prints is to examine more carefully those areas, which would most likely be touched by persons who have been on the scene. The natural manner in which a person would use and place his hands in making an entrance or exit from a building or in handling any object is the key to the discovery of latent prints.

Where a forced entrance has been made, latent prints are likely to be found on any surface adjacent to or at that point. Any object with a smooth, non-porous surface is likely to retain latent prints if touched. Fingerprints on rough surfaces are usually of little value. If the fingermark does not disclose ridge detail when viewed under a reading glass, the chances are that its value in identification is nil when photographed. Where fingermarks are found, it will be necessary for the investigator to compare them against the ones of persons having legitimate access to the premises so that the traces might be eliminated as having evidentiary value if they prove to be from these persons. Places to search for prints on an automobile are the rear view mirror, steering wheel hub, steering column, windshield dashboard and the like.

Dusting of surface may be done with a fine brush or with an atomizer. The whit powders used are basically finely powdered white lead, talc, or chalk. Another light powder is basically Chemist’s gray. A good black powder is composed of lampblack, graphite, and powdered acacia. Dragon’s blood is good powder for white surface and can be fixed on paper by heating. In developing latent prints, the accepted method is to use the powder sparingly and brush lightly. Do not use powder if the fingermark is visible under oblique lighting. It can be photographed. A good policy for the novice is to experiment with his own prints on a surface similar to the one he wishes to search in order to determine the powder best suited to the surface. Fingerprints after dusting may be lifted by using fresh cellulose tape or commercially prepared material especially designed to lift and transfer dusted latent fingerprints.

In addition to latent prints, the investigator must not overlook the possibility of two other types of fingerprint traces: molded impression and visible impression. Molded impressions are formed by the pressure of the finger upon comparatively soft, pliable, or plastic surfaces producing an actual mold of the fingerprint pattern. These can be recorded by photograph without treating the surface, is usually most effective in revealing the impressions clearly. Visible impressions are formed when the finger is covered with some substance which is transferred to the surface contacted. Fingers smeared with blood, grease, dirt, paint, and the like will leave a visible impression. If these impressions are clear and sharp, they are photographed under light without ant treatment. Ordinarily, prints of this type are blurred or smeared and do not contain enough detail for identification by comparison. However, they can not be overlooked or brushed aside without first being examined carefully.

A Existing management research does not tell us much about how to find and develop high-flyers, those people who have the potential to reach the top of an organisation. As a result, organisations are left to formulate their own systems. A more effective overall policy for developing future leaders is needed, which is why the London Business School has launched the Tomorrow’s Leaders Research Group (TLRG). The group contains representatives from 20 firms, and meets regularly to discuss the leadership development of the organisations’ high-flyers.

B TLRG recognises just how significant line managers are in the process of leadership development. Unfortunately, with today’s flat organisations, where managers have functional as well as managerial responsibilities, people development all too often falls victim to heavy workloads. One manager in the research group was unconvinced by the logic of sending his best people away on development courses, ’only to see them poached by another department or, worse still, another firm’. This fear of losing high-flyers runs deep in the organisations that make up the research group.

C TLRG argues that the task of management is not necessarily about employee retention, but about creating ’attraction centres’. ’We must help line managers to realise that if their companies are known as ones that develop their people, they will have a greater appeal to high-flyers,’ said one advisor. Furthermore, selecting people for, say, a leadership development programme is a sign of commitment from management to an individual. Loyalty can then be more easily demanded in return.

D TLRG has concluded that a company’s HR specialists need to take action and engage with line managers individually about their role in the development of high-flyers. Indeed, in order to benefit fully from training high-flyers as the senior managers of the future, firms must actually address the development of all managers who will be supporting the high-flyers. Without this, managers will not be in a position to give appropriate advice. And when eventually the high-flyers do move on, new ones will be needed to replace them. The next challenge will be to find a new generation of high-flyers.

Most of us know about the Nobel Prize, especially the Nobel Peace Prize, but few of us know anything about the man who set them up. His name was Alfred Nobel. He was a great scientist and inventor himself. Besides, he had a big business. His business may surprise you. He made and sold explosives. His companies even made and sold weapons. Isn’t this something that surprises you? The man who made money from weapons should set up the Peace Prize?

Though Alfred Nobel had a lot of money from weapons, he hated war. He hoped that there would be no war in the world. He was one of the richest in Europe. When he died in 1896, he left behind him a lot of money and his famous will. According to his will, most of his money was placed in a fund. He wanted the interest from the fund to be used as prizes every year. We know them as the Nobel Prizes. The Nobel Prizes are international. Alfred Nobel wanted the winners to be chosen for their work, not the country they came from.

Alfred Nobel had given his whole life to his studies and work and to the benefits of mankind. He made money all by his own efforts, but he left the world share his wealth. His inventions and wealth stay with the world for ever.
