LET has therefore no meaning when applied to photons. However, many authors speak of "gamma LET" anyway, [6] where they are actually referring to the LET of the secondary electrons, i.e., mainly Compton electrons, produced by the gamma radiation. [7] The secondary electrons will ionize far more atoms than the primary photon. This gamma LET has ...
Prior to December 1, 1973, Prell billings were coordinated by Benton & Bowles. [4] In advertisements the quasi-liquid Prell would induce a pearl to sink slowly to the bottom of a container. [5] Procter & Gamble sold the brand to Prestige Brands International in November 1999. Prestige then sold Prell, along with its other two shampoo brands ...
A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. The term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to ...

Higher pressures are typically required to condense these new environmentally friendly refrigerants compared to those that are being phased out. Small diameter copper tubes are more desirable in applications with higher pressures. For tubes of the same thickness, smaller diameter tubes can withstand higher pressures than larger diameter tubes.
R-410A was invented and patented by Allied Signal (now Honeywell) in 1991. [5] Other producers around the world have been licensed to manufacture and sell R-410A. [6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...
Figure (1) showing typical velocity flow profile for natural gas measurement. The most commonly used description of flow conditions within the pipe is the flow velocity profile. Fig.(1) shows the typical flow velocity profile for natural gas measurement. [4] The shape of the flow velocity profile is given by the following equation,
For example, at a given time one building may be utilizing chilled water for air conditioning and the warm water it returns may be used in another building for heating, or for the overall heating-portion of the DHC network (likely with energy added to boost the temperature). [3] [4] [5]
