Abdomen. Anatomical terminology. [ edit on Wikidata] In human anatomy, the hepatic portal system or portal venous system is the system of veins comprising the portal vein and its tributaries. The other portal venous system in the body is the hypophyseal portal system. [1]
A laboratory information management system ( LIMS ), sometimes referred to as a laboratory information system ( LIS) or laboratory management system ( LMS ), is a software -based solution with features that support a modern laboratory 's operations. Key features include—but are not limited to— workflow and data tracking support, flexible ...
An AC-AC converter with approximately sinusoidal input currents and bidirectional power flow can be realized by coupling a pulse-width modulation (PWM) rectifier and a PWM inverter to the DC-link. The DC-link quantity is then impressed by an energy storage element that is common to both stages, which is a capacitor C for the voltage DC-link or ...
Alternating current ( AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy ...

An operating system is difficult to define,[7]but has been called "the layer of softwarethat manages a computer's resources for its users and their applications".[8] Operating systems include the software that is always running, called a kernel—but can include other software as well. [7][9]The two other types of programs that can run on a ...
v. t. e. A steam turbine used to provide electric power. An electric power systemis a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical gridthat provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the ...
An electric generatoris mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy. Electric motors can be powered by direct current(DC) sources, such as from batteries or rectifiers, or by alternating current(AC) sources, such as a power grid, invertersor electrical generators.
