Detrimental effects to quantitative interpretation of Mie and laser-induced fluorescence images of hollow-cone sprays were investigated. The attenuation of the laser beam leads to locally unknown intensities rendering it impossible to obtain high-fidelity images of these sprays. Two strategies that use bidirectional illumination of the spray are discussed and evaluated. Conditions for which a b...

statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...

Guinea pigs were inoculated with Rocky Mountain spotted fever by the aerosol, conjunctival, subcutaneous, intragastric, and intranasal routes. Rickettsial infection was produced by all routes except intragastric. All animals with clinical signs of disease developed agglutinating antibody, and most developed a cell-mediated immune response. Disease produced by all experimental routes (except int...

The innovation in software analysis and various available programming facilities have urged the designers at various levels to do indispensable calculations for engine flows. Presently, the 3-D analysis approach is under practice to do simulations for various parameters involving engine operations using various softwares, “Fluent” being the trendiest at the moment for CFD modeling. The present ...
