Employee involvement teams is a general term that can include such commonly used team concepts as Fab Improvement Teams and Quality Circles. They are relatively permanent teams, composed of people who, generally, work together. They may be all working in the same department, or in 2 or 3 departments handling sequential steps of a common process. It is usual for them to work in the same physical location and in close proximity.

1) Exposure Level
2) ElectroLuminescent
The result of the movement of electrons in a conductor when the electric field is raised to a very high level and the operating temperature is high. This results in a physical displacement of conductor atoms. If the conditions are severe at high current densities, this eventually leads to an open conductor and circuit failure.
- Electromagnetic Radiation
Radiant energy created by the acceleration of an electron or other charged particle. This energy travels through space or through matter as waves. Depending on the wavelength it exists as radio waves, infrared (heat) radiation, visible light, ultraviolet radiation, X-rays or gamma rays. The emission of electromagnetic radiation from electrical equipment of various types has been implicated in recent years as causing cancer and other illnesses in the human population. The issue is still under study, although the most recent research suggests that any effects are probably more modest than was originally thought.

This scheme is laid out in a Regulation of the European Community published in July 1993. The Regulation requires Member States of the European Community to set up national systems whereby industrial sites can obtain a validation from accredited validators that their site environmental management systems are in line with the Regulationis model system, and obtain a registration of this validation at the EC level.

A way of making data indecipherable while it is being sent from computer to computer.
The capacity to do work or produce a change, for example, to move an object from one place to another or to change its temperature. Energy cannot be destroyed or created; however, the form of the energy can be changed. For example, the chemical energy available in coal because of its chemical composition can be converted to heat energy through burning, and the heat energy released through burning can subsequently be converted to electrical energy by coupling the burning with the appropriate transfer technology associated with power generating facilities. Sources of energy used to generate electricity include the chemical energy associated with fossil fuels (coal, oil, and natural gas), the radiochemical energy associated with nuclear fuels, the potential energy associated with water held behind dams, and the kinetic energy associated with winds.
A form of resource recovery in which the organic fraction of waste is converted to some form of usable energy, such as burning processed or raw refuse to produce steam.
In semiconductor jargon, the engineering phase is where hardware and software tests are developed.

Electronic Numerical Inegrater And Computer (first computer)

Entitlement is the best a company can do without adding resources. In fact, a company will need fewer resources to perform at entitlement than it did at baseline. Entitlement performance is invariably better than the baseline and almost always better than the industry benchmark. In other words, a company operating at entitlement is very competitive.
In its most general meaning, the term "environment" is used to indicate the aggregate of the conditions that make up the surroundings of an individual or community. The components of an environment include climate, physical, chemical, and biological factors, nutrients, social and cultural conditions. These influences affect the form and survival of individual and communities. This meaning is also used in the definition of Ecology (relationship between living beings and their environment).
Sometimes "environment" is defined not from the organism, but from the characteristics of the area where such organism lives (i.e. marine environment, forest environment, etc.).
The word "environment" is derived from the Latin verb "ambire=to go around".
Assessment of the environmental issues present at a particular site. It can be used for the following purposes:
1) an internal investigation of an industrial site's compliance with environmental regulations.
2) a study of a site prior to a real estate transaction to uncover potential environmental liability associated with the property, such as the prior improper disposal of hazardous waste in the ground.
3) a tool to periodically examine in a systematic and objective manner the conformance of a site's environmental activities with the requirements of its environmental management system.
It is a balance around a production site or an activity which accounts for all the factors having an impact of the environment. The inputs consist of all the various resources utilized (water, energy, chemicals, etc) and the outputs consist of all the various releases from the process activities (air emissions, waste, discharges, etc.). Environmental balances can be used to quantify the fate of a site's inputs, to quantify environmental performance indicators (generally, the ratio of specific outputs to specific inputs), and to follow trends over the years.
- Environmental Impact Assessment (EIA)
An evaluation of the environmental impacts which an existing site is having, or a future site could have, on the environment so as to determine if the impacts are acceptable or have to be reduced. In most industrialized countries EIA are required by law for various new large-scale industrial projects. The results of these formal EIA are reported in Environmental Impact Studies (EIS).
Company's overall aims and principles of action with respect to the environment including compliance with all relevant regulatory requirements regarding the environment.
A brief report required by EMAS which explains what the site does and what are the significant environmental impacts linked to its activities, gives data on the site's environmental performance, and outlines the site's major environmental objectives. This report is publicly available and must be updated every year.

A situation where rivers, lakes, streams, or other bodies of water are characterized by the excessive growth of aquatic plants. This in turn makes the water anoxic (removes the dissolved oxygen) which causes the fish and other aquatic species which rely on the dissolved oxygen to die. Eutrophication occurs when water bodies are enriched with excessive amounts of plant nutrients, in particular nitrates and phosphates. The major source of excess plant nutrients are fertilizers used on agricultural fields which are carried off by rain, but industrial discharges are also at fault. Household detergents were also considered a major source of phosphates - most industrialized countries now sell only non-phosphate based detergents.
