12,000.00 Btu IT /h. 2,593.90 ft⋅lbf/s. A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It was originally defined as the rate of heat transfer that results ...
[14] One year after the release of the TR-1 sales approached the 100,000 mark. The look and size of the TR-1 were well received, but with only four transistors the sound quality was poor, and the reviews of the TR-1's performance were typically adverse. [12] [11] The Regency TR-1 was patented [15] by Richard C. Koch, former Project Engineer of ...

It provides day and night, high-altitude (70,000 feet, 21,300 meters ...
Type 1 regulatory T cell. Type 1 regulatory cells or Tr1 (TR1) cells are a class of regulatory T cells participating in peripheral immunity as a subset of CD4+ T cells. Tr1 cells regulate tolerance towards antigens of any origin. Tr1 cells are self or non-self antigen specific and their key role is to induce and maintain peripheral tolerance [1 ...
The TR-1 Temp (Russian: Темп-С, Temp-S, meaning 'Speed') was a mobile theatre ballistic missile developed and deployed by the Soviet Union during the Cold War.
