Energy Technology
Energy technology is an interdisciplinary engineering science having to do with the efficient, safe, environmentally friendly, and economical extraction, conversion, transportation, storage, and use of energy, targeted towards yielding high efficiency whilst skirting side effects on humans, nature, and the environment. For people, energy is an overwhelming need, and as a scarce resource, it has been an underlying cause of political conflicts and wars. The gathering and use of energy resources can be harmful to local ecosystems and may have global outcomes. Energy is also the capacity to do work. We can get energy from food. Energy can be of different forms such as kinetic, potential, mechanical, heat, light etc. Energy is required for individuals and the whole society for lighting, heating, cooking, running, industries, operating transportation and so forth. Basically there are two types of energy depending on the source s they are; 1.Renewable Energy Sources 2.Non-Renewable Energy Sources

MV Pribilof
MV Pribilof was an American refrigerated cargo ship in commission in the fleet of the United States Fish and Wildlife Service (USFWS) from 1964 to 1970 and in the fleet of the U.S. National Oceanic and Atmospheric Administration′s National Marine Fisheries Service (NMFS) from 1970 to 1975. She ran a cargo service between Seattle, Washington (state) , and the Pribilof Islands – the last of the United States Government "Pribilof tenders" to carry out this function – and also made USFWS and NMFS research cruises in the Pribilofs. Prior to her USFWS service, Pribilof was the United States Army cargo ship FSR-791. After the NMFS decommissioned her, she operated as a commercial cargo ship and later as a commercial factory ship.

Surface Transportation Board
The Surface Transportation Board (STB) of the United States is a federal, bipartisan, independent adjudicatory board. The STB was established in 1996 to assume some of the regulatory functions that had been administered by the Interstate Commerce Commission when the ICC was abolished. Other ICC regulatory functions were either eliminated or transferred to the Federal Motor Carrier Safety Administration or to the Bureau of Transportation Statistics within DOT. The STB has broad economic regulatory oversight of railroads, including rates, service, the construction, acquisition and abandonment of rail lines, carrier mergers and interchange of traffic among carriers. The STB also has oversight of pipeline carriers, intercity bus carriers, moving van companies, trucking companies involved in collective activities and water carriers engaged in non-contiguous domestic trade. The Board has wide discretion, through its exemption authority from federal, state and local laws, to tailor its regulatory activities to meet the nation's changing transportation needs.

Control Rod
Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves fissioning. These elements have different neutron capture cross sections for neutrons of various energies. Boiling water reactors (BWR), pressurized water reactors (PWR), and heavy-water reactors (HWR) operate with thermal neutrons, while breeder reactors operate with fast neutrons. Each reactor design can use different control rod materials based on the energy spectrum of its neutrons.

Panel Van
A panel van (or panelvan) is a form of solid (rigid-bodied, non-articulated) van, smaller than a lorry or truck, without rear side windows. In the UK this body style is referred to as a "car-derived van" and in North American as a "sedan delivery" (while the term "panel van" or "cargo van" generally refers to larger, truck-based vans such as the Ford E-Series and Chevrolet Express). In Australia panel vans were a development of the Australian "ute" (utility), a variety of pickup, based on a car chassis, these often utilizing the floorpan of the station wagon model. In North America a two-door station wagon base was used with only front seats and steel sheet-metal panels in place of the rear and side windows. Panel vans are widely used in many parts of the world for transporting cargo. In some national usages it is distinct from a purpose-designed van in that it is based on the chassis of a family car design. In places where they are distinct from a "van", they have less cargo space but better agility and maneuverability, making them particularly suited for cities with narrow streets or heavy traffic.

Cromemco Dazzler
Cromemco's Dazzler (or TV DAZZLER) is a graphics card for S-100 bus computers. Released in 1976, it is the first commercial color bit-mapped graphics card available for microcomputers. Multiple Dazzler cards could be installed in a single machine and synced together, a feature which could, with minor modification, be used to genlock. Genlocked Dazzler cards drove ColorGraphics Weather Systems displays that generated most of the weather imagery seen on US television in the early 1980s.

Possessions of Muhammad
The possessions of the Islamic prophet Muhammad are a group of his items and possessions such as weapons, animals and others known with unique names. There is doubt about the attribution of these possessions to Muhammad, as many of them were lost during wars and tribulations. The scholar Ahmed Taymour says - after listing the remnants attributed to Muhammad in Constantinople (later Istanbul): "It is no secret that some of these remnants are likely to be true. However, we did not see any of the trustworthy people who mentioned it with proof or denial, for Allah (God), Glory be to Him, who knows about it best, and some of them cannot conceal what the idea or notion that stumbles on of suspicion and disputes it in doubts." The emir Ahmad Ibn Tulun mentioned in his book “Mufākahat al-Khullān fī Hawādith Az-Zamān”, in the incidents of the year 19 AH (640 CE) and 900 AH (1500 CE) that some claimed that they had a mug and some crutches of Muhammad and that “it was found that they are not of the possessions of the Prophet Muhammad, but rather they are the fragments of Al-Layth ibn Sa'd." The scholar Al-Suyuti said, on the authority of Muhammad (his garment): "This (the possessions) was used by the caliphs to inherit it and put it on their shoulders in processions sitting and riding, and it was on the able-bodied when he was killed and contaminated with blood, and I think it was lost in the temptation of the Tatars, for we belong to Allah (God) and to Him we shall return."

Quad Flat No-leads Package
Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe (MLF) and SON (small-outline no leads), is a surface-mount technology, one of several package technologies that connect ICs to the surfaces of PCBs without through-holes. Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide electrical connections to the PCB. Flat no-lead packages include an exposed thermal pad to improve heat transfer out of the IC (into the PCB). Heat transfer can be further facilitated by metal vias in the thermal pad. The QFN package is similar to the quad-flat package (QFP), and a ball grid array (BGA).

Industrial Fan
Industrial fans and blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine. The flow rates of these mechanical fans range from approximately 200 cubic feet (5.7 m3) to 2,000,000 cubic feet (57,000 m3) per minute. A blower is another name for a fan that operates where the resistance to the flow is primarily on the downstream side of the fan.
