conclusions the efflux pump may play a role in antibiotic resistance in a. baumannii isolates. the ability of a. baumannii isolates to acquire drug resistance by the efflux pump mechanism is a concern. thus, new strategies are required in order to eliminate the efflux transport activity from resistant a. baumannii isolates causing nosocomial infections. background acinetobacter baumannii has em...
Background and Objectives: Prevention of obesity and overweight and the associated risk factors such as insulin resistance from an early age, is of particular importance. The aim of this study was to investigate the effect of 12-week Body Pump and combination of Cinnamon and Honey on resistin, visfatin and insulin resistance in overweight children. Materials and Methods: The present applied an...
in the present study, saffron was dried using a heat pump-assisted hybrid photovoltaic-thermal solar dryer. the effect of different drying air temperatures at three levels (40, 50, and 60oc) and two different modes of the dryer (with and without heat pump system) were investigated on drying behaviour of saffron. after collecting the pertinent data, eleven drying models were used to describe dry...
Magnetite has a different electrical resistance behavior with temperatures below and above the Verwey temperature. Here, we report on Verwey transition in Fe3O4 by means of the frequency-doubled output from the Ti-sapphire laser in pump-probe experiments and from the insulator to metal transition observed by changing the temperature at the wavelength 370nm (~3.36 eV) both for pump and probe. We...
Background: Liver dysfunction during on-pump coronary artery bypass graft surgery (CABG) is a rare complication but is associated with significant morbidity and mortality. The ability to identify high-risk patients may be helpful in planning appropriate management strategies. We aimed to evaluate the factors influencing liver function tests during on-pump CABG.Methods: In 146 patients scheduled...
Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...
there are several techniques in use for non-linear refractive index measurement, namely, interferometric techniques, in which conventional inter-ferometers are used, degenerate for wave mixing (dfwm), and z-scan, each of these techniques suffers from some shortcmings. for example conventional interferometers like fabry-perot and twyman-green need high quality optical components, unwanted reflec...
Introduction: As off pump Coronary artery bypass grafting surgery (CABG) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. In this observational study we tried to show the rate and outcome of conversion . Material and methods: In this descriptive study about 477 coronary off-pump CABG patients were operated in Ghaem hos...
This paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. As a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. Unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. Furtherm...
