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 ...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

treatment of bone metastases comprises over 10% of the workload of a radiation-oncology center. bone metastases produce severe pain and immobility, necessitate narcotic use, and reduce the quality of life. a good palliative treatment must be complete, free from side effects and fast; thus we decided to evaluate strontium-89 (89sr) effectivity for palliation of breast and prostate cancer bone me...

β-cyclodextrin sulfuric acid as a green lewis acid catalyst has been applied for the preparation of bis(indolyl)methanes, tris(indolyl)methanes and 3,3'-diindolyloxindole derivatives by the condensation of indoles with various carbonyl compounds in aqueous media with high to excellent yields.

drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

multiple sclerosis (ms) is an autoimmune disease characterized by recurrent episodes of demyelination and axonal lesion mediated by cd4+ t cells with a proinflammatory t helper (th)1 and th17 phenotypes, macrophages, and soluble inflammatory mediators. the overactive  pro-inflammatory  th1  cells  and  clonal  expansion  of  b  cells  initiate  an inflammatory cascade with several cellular and ...

stevia rebaudiana bertoni is a medicinal, perennial and herbaceous plant from asteraceae family with sweet glycosides in its leaves. salinity stress is one of the important limiters in agricultural productions. salinity influences the growth and development of plant by effect on more activities in physiological and morphological characteristics. to study the effect of salinity on morphological ...
