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).

CHEMICALS / ELEMENTS |
|
A chemical element, often called simply element, is a chemical substance that cannot be divided or changed into other chemical substances by any ordinary chemical technique. The smallest unit of this kind of chemical substances is an atom, and the term "atom" is typically used to refer to atoms of particular elements. An element is a class of substances that contain the same number of protons in all its atoms. Chemicals are made from Chemical Elements.

CHEMISTRY |
|
Chemistry (derived from alchemy) is the science of matter at or near the atomic scale. In this pursuit chemistry deals with the properties of such matter, the tranformations of matter and the interactions of matter with other matter and with energy.

ELECTRONIC DATA RECOVERY |
|
Electronic Data recovery is the process of recovering data from primary storage media when it cannot be accessed normally. This can be due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.

ELECTRONIC DISCOVERY |
|
Electronic Discovery refers to Discovery (law) in Civil litigation which deals with information in electronic form. Electronic information is different from paper information because of its intangible form, volume, transience and persistence. Also, electronic information is usually accompanied by Metadata, which is rarely present in paper information. Electronic discovery poses new challenges and opportunities for attorneys, their clients, technical advisors and the courts as electronic information is collected, reviewed and produced. Electronic discovery is the subject of amendments to the Federal Rules of Civil Procedure which are effective December 1, 2006.[1]

FORENSIC COMPUTERS |
|
Computer forensics is application of the scientific method to digital media in order to establish factual information for judicial review. This process often involves investigating computer systems to determine whether they are or have been used for illegal or unauthorized activities. Mostly, computer forensics experts investigate data storage devices, either fixed like hard disks or removable like compact disks and solid state devices.

PHOTOGRAPHY |
|
Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)

PLASTICS |
|
Plastic covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastics ensures their use in almost all industrial segments.

TECHNOLOGY |
|
Technology is a word with origins in the Greek "technologia" ("τεχνολογία") "techne", "τέχνη" ("craft") and "logia", "λογία" ("saying")." "Technology" is a broad term dealing with the use and knowledge of humanity's tools and crafts.

TOXICOLOGY |
|
Toxicology is the study of the adverse effects of chemical, physical or biological agents on living organisms and the ecosystem, including the prevention and betterment of such adverse effects.
