Abstract: This paper proposes a new analysis method for photovoltaic (PV) modules. The main objectives are to obtain the resistance parameters of PV modules by adjusting I-V equation and voltage equation of diode and to find the relationship between resistance parameters and power. Firstly, values of serial resistance and parallel resistance at maximum power point are concluded. Secondly, the c...

Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Background: Visfatin is an adipokine secreted from visceral adipose tissue and involved in glucose homeostasis. The aim of the present study was to investigate the effect of eight-week resistance training on plasma visfatin levels and its relation to insulin resistance in insulin-resistant male rats. Methods: In this experimental study twenty-four Wistar male rats (220±20 gr) were acclimati...
background: multidrug resistance and production of extended spectrum β-lactamases (esbls) by enteric gram-negative rods in hospitals and community continue to be worsened. we aimed to characterize the multidrug resistance and determine the prevalence of esbl production by clinical isolates of enterobacteriaceae in southeast iran. methods: gram-negative bacteria isolated from clinical samples ...
background and objective: the d-test is performed by placing clindamycin and erythromycin impregnated disks at a standard distance on the agar plate then looking for the flattening of inhibition zone around the clindamycin disk. a positive d-test indicates clindamycin inducible resistance and also predicts treatment failure possibility of this antibiotic in clinic. prevalence of staphylococcal ...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
