a synoptic method based on stream analysis is applied to understand the governing mechanism of summer rainfall occurrence in the south of iran. based on this, the rainfall data of 152 stations of iran were analyzed for a 33-year period (1970-2002). investigating the spatial and temporal distribution of summer rainfall, a typical rainy region is recognized in the south east of iran. it is found ...

activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...

rice (oryza sativa l.) is one of the iran's most strategic crops with water shortage as the most important abiotic stress limiting its yield. in the present research the effects of: variety, water regime, nitrogen (n) and phosphorus (p) levels on n, p and k uptake were studied under greenhouse conditions. the experiment design was a factorial one based upon a randomized complete blocks of ...

nitrogen forms exert significant effects on physiological and morphological characteristics of plant. in this study, the effects of ammonium, nitrate, and ammonium-nitrate on pepper plants were investigated in soil culture, as well as in solution culture. in the soil culture, 3, 4-dimethylpyrazole phosphate (dmpp) was used as a standard nitrification inhibitor to guarantee the presence of ammon...

the aim of this research was to evaluate the effect of one session of exhaustive exercise with low intensity (55-65% vo2max), moderate intensity (65-75% vo2max) and high intensity (75-85% vo2max) on adiponectin in active women. for this purpose, 30 healthy women (mean age 21.6 years, weigh 59.7+3.35 kg, vo2max 39.1+0.58 ml/kg/min, no history of cardiovascular diseases and diabetes) were selecte...

introduction earth has ever been exposed to environmental hazards. the hazards are continually occurring in the world in the recent years. among them, atmospheric elements have created many human and financial losses in different regions. one of the hazards is dust events and in its severe case is dust storm. it happens more frequently in arid and semiarid regions in deserts and their surroundi...

background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...

this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...
