introduction : staphylococcus aureus colonization has been recognized as one of the most important risk factors for subsequent infections with this microorganism. in this study, we intended to identify all patients who were mrsa-positive upon admission and compare the prevalence of mrsa colonization on different days of study admitted in imam reza hospital in mashhad, iran. methods : this cross...
Raising domestic tax revenues is a priority for most sub-Saharan African countries. But the tax bases in most African countries are undermined by widespread tax avoidance and evasion. A new study from CMI supports the claim that improved knowledge about the tax system makes a difference in people’s willingness to pay tax. The study shows that exposure to Value-AddedTax (VAT) makes people take a...
Fine excipient particles or 'fines' have been shown to improve the dispersion performance of carrier-based formulations for dry powder inhalation. Mechanistic formulation studies have focussed mainly on explaining this positive effect. Previous studies have shown that higher drug contents may cause a decrease in dispersion performance, and there is no reason why this should not be true for fine...
Inhibition of the mitochondrial permeability transition pore (MPTP) by the novel inhibitor GNX-4975 was characterized. Titration of MPTP activity in de-energized rat liver mitochondria allowed determination of the number of GNX-4975-binding sites and their dissociation constant (Ki). Binding sites increased in number when MPTP opening was activated by increasing [Ca(2+)], phenylarsine oxide (PA...
in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...
introduction: water is the main carrier of herbicides (hc) that its quality plays an important role in herbicide performance hard water has a high concentration of ca++ and mg++ and reviews have shown that calcium, manganese and zinc are the main factors reducing the effectiveness of weak acid herbicides. weak acid herbicides such as glyphosate, paraquat, clethodim and 2, 4 d are compounds that...
Carbon nanotubes (CNTs) are being considered for a wide range of electronic device applications due to their high carrier mobility, high thermal conductivity, desirable mechanical and optical properties, relative ease of manufacture, and ability to carry extremely high current densities. One promising potential application for carbon nanotubes is as vias (vertical interconnects) in three-dimens...
تا کنون یون های واکنشگر مختلفی برای یونیزاسیون شیمیایی در روش یونش نرم مورد استفاده قرار گرفته اند که این یون ها شامل +ch5+، nh4+، no و+h3o می باشند. از بین این یون ها +no و +h3o که با اجزاء هوا واکنش نمی دهند ولی با بیشتر گونه های آلی و معدنی واکنش سریعی دارند دارای اهمیت می باشند. یون واکنشگر معمول در دستگاه طیف سنج تحرک یونی، +h3o است. در این پایان نامه یون +no بعنوان یون واکنشگر جدید و اصلی...
Optical networks need added intelligence and performance at the edge to efficiently link broadband access infrastructure to the optical multi-provider transport environment. Intelligent edge ruting platforms deliver carrier-class performance and reliability essential to the delivery of next-generation services requiring end-to-end QoS, diversified levels of security and users’ network self-conf...
