Police Support Unit
The Police Support Unit, also known by their nickname of the Black Boots, is a paramilitary wing of the Zimbabwe Republic Police. They were founded as a native police force but later developed into a counter-insurgency unit of the British South Africa Police in Rhodesia during the Rhodesian Bush War. The unit was the only paramilitary unit retained by the Zimbabwe Republic Police after the country's reconstitution as Zimbabwe. The unit gained notoriety for being an effective counter-terrorist force but received criticism in the latter stages of the Bush War as well as under Zimbabwean control for utilising brutal tactics against their targets. Rhodesian history The Police Support Unit had its origins in 1898 when 150 Ngoni tribesmen were recruited by the British South Africa Company as auxiliary native police to the British South Africa Police in Company-ruled Rhodesia. For most of their existence, they were mostly relegated to ceremonial duties, leading to them being giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairchild F8
The Fairchild F8 is an 8-bit microprocessor system from Fairchild Semiconductor, announced in 1974 and shipped in 1975. The original processor family included four main 40-pin integrated circuits (ICs); the 3850 CPU which was the arithmetic logic unit, the 3851 Program Storage Unit (PSU) which contained of program ROM and handled instruction decoding, and the 3852 Dynamic Memory Interface (DMI) or 3853 Static Memory Interface (SMI) to control additional RAM or ROM holding the user programs or data. The 3854 DMA was an optional system that added direct memory access into the RAM controlled by the 3852. A minimal system containing a 3850 and 3851 also included four 8-bit data ports, 64 bytes of RAM, and a user program on ROM. This allowed microcontroller applications to be built using just two chips. It also meant that any application that did not fit the simple requirements generally required at least three 40-pin ICs, the CPU, PSU and either the 3852 or 3853 along with additio ...

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Practical Salinity Unit
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Power Supply Unit (computer)
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage. Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5-volt standby (5VSB) power so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. The most recent ATX PSU standard is version 3.0 as of mid-2022. Functions The desktop computer power supply convert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Supply Unit
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible pow ...

Polysulfone
Polysulfones are a family of high performance thermoplastics. These polymers are known for their toughness and stability at high temperatures. Technically used polysulfones contain an aryl- SO2-aryl subunit. Due to the high cost of raw materials and processing, polysulfones are used in specialty applications and often are a superior replacement for polycarbonates. Three polysulfones are used industrially: polysulfone (PSU), polyethersulfone (PES/PESU) and polyphenylene sulfone (PPSU). They can be used in the temperature range from -100 to +200 °C and are used for electrical equipment, in vehicle construction and medical technology. They are composed of para-linked aromatics, sulfonyl groups and ether groups and partly also alkyl groups. Polysulfones have outstanding resistance to heat and oxidation, hydrolysis resistance to aqueous and alkaline media and good electrical properties. Nomenclature The term "polysulfone" is normally used for polyarylethersulfones (PAES), s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passenger Service Unit

Prudential Staff Union
The Prudential Staff Union was a trade union representing workers at the Prudential insurance company, in the United Kingdom. The only union of insurance workers to affiliate to the Labour Party, it was briefly represented on its National Executive Committee, and for a time sponsored a Member of Parliament. History In the 1900s, many staff at the Prudential were represented by the National Association of Prudential Assurance Agents (NAPAA). It was led by socialist activists and frequently came into conflict with the company, particularly in its calls for a Charter of Rights for employees. The Prudential Staff Federation was founded in October 1909 as a more moderate rival union. It claimed that the NAPAA was undemocratic, and that it excluded staff other than agents from membership. In contrast, it admitted even superintendents into membership, and called for workers to help the company be more prosperous, an approach strongly favoured by the company's management. H. Birn ...
