Background: One of the treatments in patients with dangerous diseases particularly heart failure, is Implantable Cardioverter Defibrillator (ICD) that is used to prevent sudden cardiac death. Regarding to the superiority of ICD rather than medical treatment, the purpose of this study is the assessment of time-dependent effective factors on the rates of entered shocks to patients with ICD. ...
a time-of-flight mass spectrometer (tof-ms) developed in our laboratory at isfahan university of technology is described here. the tof-ms instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. the tof-ms has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...
As important pests, scarab beetle larvae survive on plant biomass and the microbiota of the fermentation chamber play an important role in the digestion of lignocellulose-rich diets. However, the cultivable microbes, especially the anaerobic cultivable microbes, are still largely unknown. Here, both cultivable anaerobic and aerobic bacterial communities associated with the fermentation chamber ...
Control of nitric oxides (NOx) is one of the key elements in designing combustion systems because of the important role on ozone layer destruction and smog formation. Because of the sensitivity of thermal NO mechanism to temperature, a practical and scientific method for thermal NO reduction is decreasing the flame temperature. Dilution is one way to reduce maximum temperature in the combustion...
This paper presents the development of a complete mobile fog chamber system, which encompasses the aspects of electronic instrumentation, video recording, fog generation system, high-voltage source, data acquisition system and monitoring instrument. The chamber has all the basic features to conduct type-tests on insulator of ceramic and nonceramic type in an environment of artificially polluted...
