many of the meteorological variables such as precipitation, strongly depend on the large scale atmospheric and ocean surface circulations.in the current study, the effect of climatic signals on the average monthly rainfall of the adjacent stations of sheshdeh and gharebolagh area was investigated during the statistical period twenty five years from 1985 to 2009. the regression and neural networ...

this study aimed at determining the evapotranspiration and crop coefficient (kc) of sugar beet during the plant growth using drainage lysimeter by using water balance and experimental methods for three years in shahrekord. after sugar beet planting and out of lysimeter, evapotranspiration was measured weekly and monthly by measuring the factors of the water- balance equation. results showed tha...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

background: previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. in the current study, effects of il-4 against morphological changes and tissue degradation induced by il-1α on bovine nasal cartilage (bnc) explants were investigated. methods: fresh bnc samples were prepared from a slaughterhouse under sterile conditions. bnc explants culture was...

background: vestibular schwannoma (vs) is one of the skull base tumors originating from vestibular portion of eighth cranial nerve. recently, 2 micro-thulium laser is used in the surgery of some intracranial tumors. objectives: assessing the efficacy of 2 micro-thulium flexible hand-held laser fiber (revolixjrò) in microsurgical removal of vs. materials and methods: this retrospective non-rando...

in this study, to determine the economic value of irrigation water and simulate the response of farmers to reducing  available water policy of positive mathematical programming models (pmp) was used. by the proposed model, the economic value (shadow price) of irrigation water estimated in each of the areas of western rodbar alamuot, rajai dasht and eastern rodbar almuot. then, the reactions of ...

the study of biochemical characteristics and metabolic activity of lactobacilli is necessary for selecting strains to be used as starter cultures for bread production. in this study, biochemical characteristics, acidification and probiotic properties of lactobacillus strains (lactobacillus plantarum, l. curvatus, l. paralimentarius) isolated from traditional sourdoughs were evaluated. all three...

in order to investigate the effect of different levels of cycosel and naphthalene acetic acid on some vegetative traits and on essential oil yield from rose-scented geranium (pelargonium graveolens heritier), an experiment was conducted in 2008 in the research greenhouse of horticulture department of zanjan university. the study was arranged as a factorial experiment, based upon a randomized co...

the behavior of suspended sediment during flood events is not only a function of energy conditions, i.e. sediment is stored at low flow and transported under high flow conditions, but also is related to the variations in sediment supply and sediment depletion. these changes in sediment availability result in so-called hysteresis effects. therefore, hysteresis pattern analysis is of great import...
