BOILERS |
|
A boiler is a closed vessel in which water or other fluid is heated under pressure. The steam or hot fluid is then circulated out of the boiler for use in various process or heating applications. A safety valve is required to prevent over pressurisation and possible explosion of a boiler.

CANCER - LUNG |
|
Lung cancer is a cancer of the lungs characterised by the presence of malignant tumours. Most commonly it is bronchogenic carcinoma (about 90%). Lung cancer is one of the most lethal of cancers worldwide, causing up to 3 million deaths annually. Only one in ten patients diagnosed with this disease will survive the next five years. Although lung cancer was previously an illness that affected predominately men, the lung cancer rate for women has been increasing in the last few decades, which has been attributed to the rising ratio of female to male smokers.

CASE REVIEWS |
|
Case review is a method of catching and correcting honest mistakes, as well as intentional falsification of results, before permanent damage is wrought. Casework must be reviewed by an independent analyst or other qualified individual lab or by a qualified independent expert on behalf of the court or opposing counsel.
Case review is often the first step initiated in order to decide if any further legal steps can or should be taken.

CASINOS / GAMBLING |
|
A casino is a building that accommodates certain types of gambling activities. Casinos are often placed near or combined with hotels, restaurants, retail shopping and other vacation attractions to encourage long stays. Some casinos are known for hosting live entertainment events, such as concerts and sporting events, especially boxing.

CIVIL RIGHTS - EQUAL RIGHTS |
|
Civil rights are the protections and privileges of personal liberty given to all citizens by law. Civil rights are distinguished from "human rights" or "natural rights"; civil rights are rights that are bestowed by nations on those within their territorial boundaries, while natural or human rights are rights that many scholars claim ought to belong to all people. For example, the philosopher John Locke (1632-1704) argued that the natural rights of life, liberty, and property should be converted into civil rights and protected by the sovereign state as an aspect of the social contract. Others have argued that people acquire rights as an inalienable gift from a god or at a time of nature before governments were formed.

COMBUSTION |
|
Combustion or burning is a chemical process, an exothermic reaction between a substance (the fuel) and a gas (the oxidizer), usually O2, to release heat. In a complete combustion reaction, a compound reacts with an oxidizing element, and the products are compounds of each element in the fuel with the oxidizing element. For example:
CH4 + 2 O2 → CO2 + 2 2O + heat
CH2S + 6 F2 → CF4 + 2 HF + SF6 + heat

COOLING TOWERS |
|
Cooling towers are structures for cooling water or other working medium to near-ambient temperature. The primary use of large, industrial cooling towers is to lower the temperature of the cooling water used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants and other industrial facilities. It is desirable to cool the water rather than simply discharging it because the cooling water is typically demineralized and it is cheaper to cool it rather than getting more demineralized water. Furthermore, discharging large amounts of hot water may raise the temperature of the receiving river or lake to an unacceptable level for the local ecosystem. A cooling tower serves to dissipate the heat into the atmosphere instead and wind and air diffusion spreads the heat over a much larger area than hot water can distribute heat in a body of water.

DUMBWAITER |
|
A small elevator used to transport food or other items between floors of a building.
An elevator is a transport device used to move goods or people vertically. Outside North America, elevators are known more commonly as lifts, although the word elevator is familiar from American movies and television shows, just as some Americans are aware of lift from imported entertainment. Other languages may have loanwords based on either elevator (e.g. Japanese) or lift (e.g. Cantonese). Because of wheelchair access laws, elevators are often a requirement in new buildings with multiple floors.

ELECTRONICS |
|
The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering.

ENGINEERING - MECHANICAL |
|
Mechanical engineering is a very broad field of engineering that involves the application of physical principles for analysis, design, manufacturing, and maintenance of mechanical systems. The system can be as simple as the design of a chair for comfort or as complex as the operations of a turbocharged engine for speed. It can be as small as the manufacturing of a nano-sized gear or as large as the structure of a supertanker used to carry oil around the world.

HELICOPTERS |
|
A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors (propellers). Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). The engine-driven helicopter was invented by the Slovak inventor Jan Bahyl. The first stable, single-rotor, fully-controllable helicopter to enter large full-scale production was made by Igor Sikorsky in 1942.

HVAC - HEAT VENTITATION AIR CONDITIONING |
|
HVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism/acronym that stands for "heating, ventilation and air-conditioning". This is sometimes referred to as climate control.
These three functions are closely interrelated, as they control the temperature and humidity of the air within a building in addition to providing for smoke control, maintaining pressure relationships between spaces, and providing fresh air for occupants. In modern building designs, the design, installation and control systems of these functions are integrated into a single "HVAC" system.
The term air handler can mean a whole unit including the blower, heating and cooling elements, filter racks or chamber and dampers, but not including the ductwork through the building.

HYDROLOGY |
|
Hydrology (from Greek: Yδρoλoγια, Yδωρ+Λoγos, Hydrologia, the "study of water") is the study of the movement, distribution, and quality of water throughout the Earth, and thus addresses both the hydrologic cycle and water resources. A practitioner of hydrology is a hydrologist, working within the fields of either earth or environmental science, or civil and environmental engineering.

MICROWAVE HEATING |
|
A microwave oven, or microwave, is a kitchen appliance employing microwave radiation primarily to cook or heat food. Microwave ovens have revolutionized cooking since their use became widespread in the 1970s.
|
POWER PLANTS |
|
A fossil fuel power plant is an energy conversion center that combusts fossil fuels to produce electricity, designed on a large scale for continuous operation.
|
REFRIGERATION SYSTEMS |
|
Refrigeration (from the Latin frigus, frost) is generally the cooling of a body by the transfer of a portion of its heat away from it. Applications include conservation, especially of food, and lowering the temperature of drinks to one that is more agreeable for consumption. Domestic refrigerators are common in kitchens, with separate sections or separate machines for cooling and freezing.
|
WWW - WORLD WIDE WEB |
|
The World Wide Web (WWW or simply the Web) is a global information space which people can read and write via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet itself, but the Web is actually a service that operates over the Internet, just like e-mail.
