existence of pollen and nectar plants in vegetation composition of natural environment is essential for apiculture as one of the utilization types in multiple uses of environmental resources. therefore, development of this strategy based on indigenous knowledge will increase stakeholder income, which can decrease stocking rate based on range grazing capacity. due to high dependence of bee to pl...

the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest  and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...

In wireless ad hoc networks, energy utilization is perhaps the most important issue, since it corresponds directly to the operational network lifetime. Topology Control (TC) is a wellknown energy saving technique which tries to assign transmission ranges of nodes to optimize their energy utilization while keeping the network connected. In current TC schemes, the transmission range of each node ...

in the present study, the root vigor and kinetic characteristics of nitrogen absorption in potato cultivars was investigated through sand cultivation and pot tests with nutrient solution. four cultivars of potatoes, namely, feiwuruita, yunshu301, liangshu97, and chuanyu56 were grown in nutrient solution matrix cultures. the result showed that: (1) nitrogen uptake rates differed significantly am...

Because the major processes involved in muscle contraction require rapid utilization of ATP, measurement of ATP utilization can provide important insights into the mechanisms of contraction. It is necessary, however, to differentiate between the contribution made by cross-bridges and that of the sarcoplasmic reticulum (SR) Ca2+ pumps. Specific and potent SR Ca2+ pump blockers have been used in ...

Class AB differential amplifiers using composite BiCMOS and bipolar transistors are introduced. Their utilization for the implementation of low voltage (+-1.65V) operational amplifiers with high slew rate and rail to rail common mode input voltage range is discussed.

drug utilization evaluation (due) studies are designed to assess drug usage appropriateness. we aim to evaluate the drug utilization of intravenous ciprofloxacin and imipenem, two of the broad spectrum antibiotics that consume a significant proportion of our hospitals’ outlay, in different wards of a teaching hospital in zabol. during a 5 months period (december 2010 to may 2011), 263 patients ...

this study was performed to assess the incidence of medication errors and irrational use of human albumin in two wards of our hospital and also aimed to evaluate the ability of pharmaceutical care center and pharmacists in improving patient care. albumin administration was evaluated for patients who received albumin during the study period, in gastroenterology and general surgery wards. the ind...

background: the need to provide high quality prenatal care services, which take account of women's views and specifi­cally address their need for information, support and communication, has been advocated and group prenatal care, had been sug­gested as one of the ways to achieve this objective. the purpose of this study was to examine the impact of group versus in­dividual prenatal care on sati...
