To alleviate water scarcity problem in arid and semiarid regions of Iran, different irrigation methods such as deficit irrigation, pressurized irrigation and partial rootzone drying (PRD) method have been suggested. In PRD method, half of the rootzone is watered and the other half is kept dry intermittently. The objective of this research was to study yield, yield components and water use effic...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
In this study, crude glycerol was used as a carbon source in the cultivation of wild yeasts, aiming for the production of microbial lipids and citric acid. Forty yeasts of different sources were tested concerning their growth in crude and commercial glycerol. Four yeasts (Lidnera saturnus UFLA CES-Y677, Yarrowia lipolytica UFLA CM-Y9.4, Rhodotorula glutinis NCYC 2439, and Cryptococcus curvatus ...
Split gill lamellae and gill cuticles of shore crabs (Carcinus maenas) adapted to 10 per thousand salinity were mounted in a modified Ussing-type chamber. With NaCl saline on both sides, split gill lamellae generated a short-circuit current (I(sc)) of -301+/-16 microA cm(-2) at a conductance (G(te)) of 40+/-2 mS cm(-2). The net influxes of Na(+) and Cl(-) were 8.3+/-2.6 and 18.2+/-2.7 micromol ...
Poly[methacrylic acid-grafted-poly(ethylene glycol)] [P(MAA-g-EG)] is a complexation hydrogel molecularly designed for oral peptide delivery. In this work, the cytotoxicity and insulin-transport enhancing effect of P(MAA-g-EG) microparticles on intestinal epithelial cells were evaluated using Caco-2 cell monolayers. A series of P(MAA-g-EG) microparticles with different polymer compositions were...
Background: Soil pollution and accumulation of heavy metals in crops in industrial areas is one of the most important environmental issues threatening the life of plants, animals, and humans. The aim of this study was to determine the concentration of Cr and Cd in the soil and barberry plants in farms surrounding the Qayen Cement Company, South Khorasan Province, Iran. Materials and Methods:...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
PURPOSE Changes in human body composition can affect the accuracy of spine bone mineral density (BMD) measurements. The purpose of this study was to evaluate whether fat and water in the soft tissue of the abdomen influence lumbar spine BMD measurements obtained using dual energy X-ray absorptiometry (DXA). MATERIALS AND METHODS Duplicate BMD measurements were carried out on healthy volunteer...
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
during this study from december 2009 to november 2011, 363deep flounder fish were caught and their weight and length were measured. the caught fish included 18 males, 200 females and 155 immature fishes. the mean, maximum and minimum total lengths were 264 ± 57 (mean ± sd), 415 mm and 115 mm respectively. the mean, maximum, and minimum total weights for this species were 238 ± 150 g, 827 g and ...
