BATTERIES |
|
In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as one or more galvanic cells, fuel cells or flow cells. The earliest known artifacts that may have been batteries are the Baghdad Batteries, from some time between 250 BCE and 640 CE. The modern development of batteries started with the Voltaic pile developed by the Italian physicist Alessandro Volta in 1800. The worldwide battery industry generates 48 billion dollars in sales annually (2005 estimate).

BICYCLE HELMETS |
|

CONTRACTS - INTERPRETATION |
|
A contract is a promis or an agreement that is enforced or recognized by the law. In the civil law, contracts are considered to be part of the general law of obligations. This article describes the law relating to contracts in common law jurisdictions.
Contract theory comprises many different theories and various interpretations of the various body of rules and subrules that define Contract Law.
Classical contract theory is the set of ideas and assumptions that underpinned the development of contract law in England and the United States during the 19th century. During this period, the prevailing liberal individualist philosophy of laissez faire elevated contract to a position of central importance in the law.

INFORMATION SYSTEMS |
|
As an area of study it is commonly referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with computer science which is more theoretical in nature and deals mainly with software creation, or computer engineering, which focuses more on the design of computer hardware.

NEUROLOGY |
|
Neurology - The medical science that deals with the nervous system and disorders affecting it. The specialist that focuses in this field is a neurologists.
Neurological disorders are disorders that affect the central nervous system (brain, brainstem and cerebellum), the peripheral nervous system (peripheral nerves - cranial nerves included), or the autonomic nervous system (parts of which are located in both central and peripheral nervous system).

POLICE PROCEDURE |
|
The documented procedures that police departments follow in order to provide consistent support and enforcement of laws in their community. The police procedural is a sub-genre of the mystery story which attempts to accurately depict the activities of a police force as they investigate crimes.

USE OF FORCE |
|
The use of force to settle conflicts is much debated in theory and in practice (see moral philosophy, ethics).When a conflict is viewed as being between parties having the same standing, observers often recommend the use of negotiation or other "conflict resolution" techniques. When a conflict is viewed as being between a law-breaker and a law-enforcer, observers tend to side with the enforcer (but with important exceptions). Analysis of conflicts, and of when and where it is legitimate for an involved (or intervening) party to use force to settle it, quickly becomes complicated.
