Abstract Recently, there has been an increasing need to prolong the quality of matured fruits promote distribution fresh consumers and processing facilities. Studies have shown that 1-methylcyclopropene (1-MCP), inhibitor ethylene, can maintain firmness several for a long duration. Therefore, aim this study was examine effect 1-MCP treatment on firmness, rind color, decay rate Japanese pear ‘Sh...
air pads are applicable in ultra precision machines very much. two main components of these machines, spindle and table, use the advantages of such systems. the performance and efficiency of air pads have big influence on the whole machine quality. parameters affecting pressure distribution of air tables may be considered as, 1) air compressing method, 2) air nozzle diameter, shape, and size, 3...
background and objective: bioaerosols are particles of microbes, viruses and derivatives; they exist in a wide variety of shapes and sizes and can be measured with different air samplers. the purpose of this study is the determination of bacterial aerosol in the air of hospitals and the determination of contaminated areas for disinfection proceedings by hospital health care teams, by selecting ...
background: contemporary development of growing urban communities and increasing the economical and industrial activities in the current century without paying attention to assess the effect of these activities on human health, as the axis of the development, is caused urban air pollution and risks from different pollutant emissions. tehran air pollution has received considerable media coverage...
air spindles are one of the main elements of precise machine tools. vibration of these spindles is one of the vital issues necessary for investigation. among parameters which influence air spindle vibrations are rotational speed, compression air method, input nozzle diameter, air gap pressure. in this study using ansys, the effects of air gap thickness on air spindle vibrations have been invest...
The mapping of air quality over the city of Strasbourg and its vicinity requires an increase of the number of measurements aiming at spatializing information about air pollutants concentrations. A methodology based on a multisource approach for mapping air pollutants concentrations over the city was presented in previous communications. One step of the methodology is the estimation of pollutant...
A quantum resonator in a thermal-equilibrium state with high temperature has large average population and is featured significant occupation over Fock states excitation number. The could be cooled down via continuous measurements on the ground of coupled two-level system (qubit). We find, however, that measurement-induced cooling might become inefficient high-temperature regime. Beyond conventi...
