In humans, blood pressure is usually measured indirectly with a special cuff over the brachialartery(in the arm) or the femoral artery (in the leg). There are two pressures measured: (1) thesystolic pressure(the higher pressure and the first number recorded), which is the force that blood...
Line positions and widths of the B 3Π o + u X 1Σ + g electronic transitions of chlorine and bromine gases are measured in absorption as functions of pressure by means of a scanning Fabry-Perot interferometer spectrometer (resolving power > 10 6). No dependences on quantum numbers are det...
System, method and apparatus for applying air pressure on a portion of the body of an individual A system is provided by applying pressure to a portion of a body of an individual in a chamber having an aperture along a vertical axis for receiving the portion of the body of the individual...
The wall function described inSection 2is theoretically valid for large adversepressure gradients, even for flows which are about to separate from the wall. To verify this, we use a parabolic code and impose a constant adversepressure gradienton a fully developed zero pressure gradient boundary lay...
Choi,Kevin Youngjune,Dempsey,Brian A 摘要: The objectives were to investigate the effects of in-line coagulation on removal of natural organic matter (NOM) and turbidity and on fouling of membranes during ultrafiltration (UF). Coagulants were added prior to UF, without intermediate use of ...
For heating, ventilation or air conditioning purposes in massive multistory building constructions, ducts are a common choice for air supply, return, or exhaust. Rapid population expansion, particularly in industrially concentrated areas, has given rise
A general definition of vapor pressure is that it is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. From: Ecotoxicology Essentials, 2016
A comprehensive search of international databases including CINAHL, Google Scholar, Cochrane Library, PubMed, HINARI, and Global Health was carried out to estimate the pooled prevalence of pre-marital sex and its association with peer pressure and watching pornography among young individuals in ...
The built-in safety device compensates for a fall in water pressure. 该内置式安全装置在水压下降时能提供保护。 来自柯林斯例句 2. With succulent, herbaceous , species, water pressure at the nozzle is critical. 对肉食植物 、 草本植物来说, 喷头的水位要求很严格. 来自辞典例句 3. Exhaust before ...
In this work we analyze how uniaxial pressure affects the topological character of BaSn2, a Dirac nodal-line semimetal in the absence of spin-orbit coupling. Using calculations based on the density functional theory and a model tight-binding Hamiltonian, we find the emergence of a second nodal ...
