Peak envelope power (PEP) is the average power over a single radio frequency cycle at the crest of the modulation. This is a Federal Communications Commission definition. PEP is normally considered the occasional or continuously repeating crest of the modulation envelope under normal operating conditions. The United States FCC uses PEP to set ...
Post-exposure prophylaxis. Other names. Post-exposure prevention. [ edit on Wikidata] Post-exposure prophylaxis, also known as post-exposure prevention ( PEP ), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring. It should be contrasted with pre-exposure prophylaxis, which ...
Phosphoenolpyruvate carboxylase (also known as PEP carboxylase, PEPCase, or PEPC; EC 4.1.1.31, PDB ID: 3ZGE) is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO 3 −) to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate:
This rating is not issued by the FSK, but may be self-applied to films seeking to educate their audience (e.g. documentaries, instructional films, etc.). Films with this rating may be sold without any age restriction provided they do not contain any material "evidently harmful to the development of children and youths". [55]
C4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960s discovery by Marshall Davidson Hatch and Charles Roger Slack. [ 1] C 4 fixation is an addition to the ancestral and more common C 3 carbon fixation. The main carboxylating enzyme in C 3 ...
Here we can instantly see the clear winners and clear losers in the spec race -- and we're also seeing a much broader spread of DPS than we'll see anywhere else (which makes sense, given the spec ...
Positive end-expiratory pressure ( PEEP) is the pressure in the lungs ( alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. [ 1] The two types of PEEP are extrinsic PEEP (PEEP applied by a ventilator) and intrinsic PEEP (PEEP caused by an incomplete exhalation).
Performance-enhancing proxies ( PEPs) are network agents designed to improve the end-to-end performance of some communication protocols. PEP standards are defined in RFC 3135 (PEPs intended to mitigate link-related degradations) and RFC 3449 (TCP performance implications of network path asymmetry). Mechanism of a Distributed Split PEP on ...
