background pseudomonas aeruginosa is one of the most important agents causing nosocomial infections worldwide. multidrug resistance of isolated bacteria from nosocomial infections makes it difficult and sometimes impossible to treat. objectives the aim of the present study was to investigate the antibiotic resistance and association between blaimp and blavim genes with resistance to meropenem a...
Today Grafting is important because of its advantageous in increasing plant resistance to temperature stress and salinity in Cucurbitaceae. In order to investigated the effect of grafting of Cucumis sativus var. Super daminos on babol and Cucurbita moschata var Ferro and Cucumis sativus collected in Isfahan comparing with non-grafting and self grafting of Cucumis sativus var. Super daminos as a...
most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...
In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
Abstract Introduction and aim: Studies has shown that increases bone mineral density (BMD) loss after menopause in women; On the other hand, physical activity is an important factor in preventing osteoporosis and fractures associated with it. The aim of this study was to determine the effects of 6 months low-load very high-repetition resistance training (body pump) on BMD and balance in postme...
The aim of the present study was to examine the effect of gender and social class differences on locus of control in a group of Junior high school students. 144 students at second and third grades of school were randomly selected by using a cluster sampling procedure. Subjects completed the Nowicki-Strickland locus of control scale, which were adopted for Iranian population by Khair (25). Khair...
Objective: Resistance exercises improve muscle strength and joint's physical status. The aim of this study was to assess the effect of progressive resistive exercise on joint's physical characteristics and quality of life in hemarthrosis joint in severe haemophilic A patients. Methods: Twenty-four severe haemophilia A patients (18-35 years old) with knee hemarthrosis, were assigned randomly to ...
This paper introduces a Transimpedance Amplifier (TIA) design capable of producing an incremental input resistance in the ohmic range, for signals microampere such as are encountered instrumentation electrochemical ampero-metric sensors, optical-sensing and current-mode circuits. low input-resistance is achieved using stage incorporating negative feedback. In Cadence simulation exemplary 180 nm...
