The aim of this study was to examine three types of superoxide dismutase (SOD) in plasma after burns, and especially to clarify the characteristics of plasma extracellular SOD (EC-SOD) in burned patients. A total of 71 blood samples were collected from 18 patients on arrival, day 1, day ...
The negative hydrogen ion produced in the peripheral region of the sheet plasma was measured with a movable Faraday cup. The maximum negative ion current was observed when the extraction electrode of the Faraday cup was biased slightly negative with respect to the plasma potential. The optimum ...
Effect of some design factors in the front panel on the characteristics of a plasma display 来自 Taylor & Francis 喜欢 0 阅读量: 48 作者:Kim, Beong Ju,Moon, Cheol Hee 摘要: Low sustained voltage (Vs) and high luminous efficiency (lumen/Watts) are required for the enhanced performance of...
The energies of the positive ions produced by the impact of a 70 nm boron carbide particle on a silver-doped aluminium target at a velocity of 94 kms(-1) have been derived for each ion species observed in the resulting time-of-flight mass spectrum. The results allow major conclusions to ...
Commercially available mullite (3Al 2 O 3 ·2SiO 2 ) powders containing oxides of calcium and iron as impurities, have been made suitable for plasma spraying by using an organic binder. Stainless steel substrates covered with Ni-22Cr-10Al-1.0Y bond coat were spray coated with mullite. The ...
Using two types of large-diameter spiral antennae, plasma with density exceeding 1012 cm-3 has been produced with several hundreds of watts of radio frequency power. By changing the magnetic field configuration near the antenna, the threshold power and the degree of the density change in a ...
The wear rates of nanostructured zirconia coatings are about four-fifths of those of conventional counterparts under a load of 5 N. The wear mechanism is also discussed. 展开 关键词: coatings friction and wear nanostructural plasma spraying zirconia ...
Electron microscopy revealed assembly by a budding process from the plasma membrane of infected cells. The average diameter of the virion was 106 nm. Intracisternal particles with an average diameter of 45 nm were present within infected cells. In two instances secondary monolayers of feline renal ...
Agah,K.M,Elahi,A.S,Ghoranneviss,M 摘要: A tokamak's plasma characteristics as well as plasma modes are analyzed in the presence of hot limiter biasing regime in the IR-T1 Tokamak. Fast Fourier transform analysis is a reliable technique for mode detection in tokamaks. For this purpose, ...
The constrictor wall heat flux characteristics of a high intensity argon arc with a transpiration cooled constrictor are discussed. An apparatus utilizing a segmented plenum chamber is described which provides in contrast to previous experiments more uniform constrictor wall temperatures. This permits lower...
