The Interaction of Rare Gases with Metals
Interaction potentialsof rare gases withmetal surfaces are calculated and compared with experimental data. A local dielectric function formalism and the density functional method are used in the calculation of the attractive and repulsive energies respectively. Depth and curvature variations of the potentials suggest a classification into light (He, Ne) and heavy rare gases. Sensitivity of the ...
متن کاملMass-spectrometer study of the rare gases.
A stu dy of the appearance potentia ls and isotope abundance of tbe rare gases has been made \yith a Consolidated Engin eering Corp. mass spectrometer as a check on the operation of th e instrument. The res ults a re comparable to previously publi shed data. In add ition, some nell' experimental value of ionization poten tials have been obtained. Generally, good agreement of the isotope ab unda...
متن کاملPrevalence of Drug Resistance in Nonfermenter Gram-Negative Bacilli
Background and Objectives: Non-fementer gram-negative bacilli (NFGB) are ubiquitous pathogen that has emerged as a major cause of health care associated infections. The aim of this study was to determine the prevalence and antimicrobial susceptibility of NFGB in an Iranian hospital. Materials and Methods: FromJuly 2005 to November 2006 a total of 257 strains of NFGB including 109 (42.41%)...
متن کاملStrong-field double ionization of rare gases.
We have studied the double ionization of helium and other rare gases using an electron-ion coincidence technique. With this scheme, the electron energy spectrum correlated to the creation of a doubly charged ion may be compiled. In all cases, the observed double ionization electron distributions are similar and enhanced at high energies, while the single ionization spectra exhibit distinct diff...
متن کاملAntibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan
Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...
