Objectives. The Loeb minimum criteria (LMC), developed by a 2001 consensus conference, are minimum standards for initiation of antibiotics in long term care settings, intended to reduce inappropriate prescribing.
NTP-Normal Temperature and Pressure. NTP is commonly used as a standard condition for testing and documentation of fan capacities: 1  NTP-Normal Temperature and Pressure-is defined as air at 20oC (293.15 K, 68oF) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 407 in H2O, 760 torr).ote that the earlier IUAPC definition of STP to 273.15 K and 1 atm (1.01325 105 Pa) is discontinued. 1 Pa = 10-6 N/mm2 = 10-5 bar = 0.1020 kp/m2 = 1.02x10-4 m H2O = 9.869x10-6 atm = 1.45x10-4 psi (lbf/in2). Standard volume of 1 mole of an ideal gas at STP is 22.4 liters.
Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. Atmospheric temperature is a measure of temperature at different levels of the Earth's atmosphere.It is governed by many factors, including incoming solar radiation, humidity and altitude.n the Earth's atmosphere, temperature varies greatly at different heights relative to the Earth 's surface. The coldest temperatures lie near the mesopause, an area approximately 85 km (53 mi) to 100 km (62 mi) above the surface.
