The studied area in this study is Marand plain with an area equivalent to 517.42 square kilometers in the North West of East Azerbaijan province. In this research, consecutive periods of meteorological and hydrogeological droughts were detected by SWI and SPI drought index at 6 periods (6, 9, 12, 18, 24 and 48 months). For this purpose was used monthly precipitation mean of 7 rain-gauge station...
The area under pulse production has decreased continuously for the last 10 years in Bangladesh. With the expansion of irrigation facilities, the area allocated to production of cereal crops has increased significantly, while pulses have been pushed to marginal lands of low productivity. Additional production of pulses can be achieved by (1) increasing productivity through improved varieties, (2...
annually, 200 ha of agh ghala rangelands in golestan, iran are under alkaligrass puccinella distans's cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. the current study aims to reduce such costs through the examination of apt sites to grow p. distans in northern rangelands of agh ghala golestan, iran. because of the ...

background: the purpose of this study was to characterize the pharmacokinetic parameters of mycophenolic acid (mpa) in iranian kidney transplant patients. methods: plasma mpa concentration of mycophenolate mofetile (mmf) 1 gram two times a day was measured in 21 iranian kidney transplant recipients receiving treatment. patients who entered the study had been transplanted for more than 3 months ...
Previously, we demonstrated a high quality of minerals formed by serum-free cultured jaw periosteal cells (JPCs) by Raman spectroscopy but the mineralization extent was not satisfactory. In the present study, we analyzed the proliferation and mineralization potential of human platelet lysate- (hPL-) cultured JPCs in comparison to that of FCS-cultured JPCs. By cell impedance measurements, we det...
The effect of 10-year continuous saffron cultivation on physical and chemical properties of a silty clay loam soil was investigated in a research farm of College of Agriculture, Shiraz University, Shiraz (52 º 33ʹ E Longitude and 29º 36ʹ N latitude), Iran. This farm was irrigated with different regimes (100% of saffron's potential evapotranspiration (ETp), 75%ETp, 50%ETp) including rain fed tre...
For the first few days of cultivation of connective tissue in hypertonic, hypotonic, and diluted medium, cell proliferation was stimulated. The first outgrowths of new cells in the modified media did not occur sooner than in normal medium. In hypertonic medium the density of the area of cell proliferation appeared to be greater than the control, but in hypotonic or diluted medium there seemed t...
in order to investigate biodiversity and production of cultivated medicinal plants in agroecosystems of qazvin province, a study was conducted during year of 2011. interviews were carried out with farmers by using semi-structured questionnaire to obtain information regarding to biodiversity and medicinal plants production systems in main regions under cultivation of medicinal plants including f...
Agricultural expansion is one of the prime driving forces of global land cover change. Despite the increasing attention to the factors that cause it, the patterns and processes associated with indigenous cultivation systems are not well understood. This study analyzes agricultural change associated with subsistence-based indigenous production systems in the lower Pastaza River Basin in the Ecua...
