The Turabay dynasty was a family of Bedouin emirs who governed the district of Lajjun in northern Palestine during Ottoman rule in the 16th–17th centuries. The family's forebears had served as chiefs of Jezreel Valley during Mamluk rule in the late 15th century. During the Ottoman conquest of the region in 1516–1517, the family aided ...
A radioisotope thermoelectric generator ( RTG, RITEG ), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This type of generator has no moving parts and ...
The use of metal-free columns allows direct labeling of 68 Ga without prepurification, hence making production of gallium-68-radiolabeled compounds more convenient. The mobile phase is a solvent able to elute (wash out) gallium-68 (III) ( 68 Ga 3+ ) after it has been produced by electron capture decay from the immobilized (absorbed) germanium-68.
The fixed rate for a 15-year mortgage is 6.17%, down 8 basis points from last week's average 6.25%. These figures are lower than a year ago, when rates averaged 6.96% for a 30-year term and 6.30% ...
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic.It is 20 to 40 times more potent than heroin and 100 times more potent than morphine; [8] its primary clinical utility is in pain management for cancer patients and those recovering from painful surgeries.
e. Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into ...
In 2003 these limits were set at a minimum of 20% and a maximum of 25%. [15] Since July 1, 2007, the mandatory blend is 25% of anhydrous ethanol and 75% gasoline or E25 blend. [16] The lower limit was reduced to 18% in April 2011 due to recurring ethanol supply shortages and high prices that take place between harvest seasons. [17]
