introduction water vapor can spread in molecular, unstable and erratic phase and can also transfer by convection and advection process. this transfer happens from the earth and ocean surfaces to the atmosphere in hot air. this type of transfer is considered as the main pattern. in the studies of the atmosphere, one of the prominent factors to be considered is the complexity of water vapor and i...

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 ...

nitro-containing heteroaromatic derivatives structurally related to nitroimidazole (metronidazole) are being extensively evaluated against helicobacter pylori isolates. on the other hand, 1,3,4-thiadiazole derivatives have also demonstrated promising antibacterial potential. in present study, we evaluated anti-h. pylori activity of novel hybrid molecules bearing nitroaryl and 1,3,4-thiadiazole ...

introduction precipitation is one of the most important meteorological variables in comparison with other climatic parameters. it varies extremely over time and space. the occurrence of this climate phenomenon requires specific circumstances in environment. its accurate measurement is important to a wide range of decision makers including hydrologists, agriculturalists, industrialists and etc. ...

introduction there are significant differences in the spatial distribution of the iran annual precipitation. this is resulted from spatial behavior of precipitation in the one hand and variation in the sources of precipitation on the other. the lack of adequate distribution of meteorological stations and the unavailability of long-term statistics of precipitation makes the analysis of precipita...

an investigation was conducted on the effects of vermicompost as an organic matter and a substitute for fertilizers during year 2007 in ferdowsi university of mashhad (fum). vermicompost was applied at five levels (0, 10, 25, 50, 100%) and phosphorus at two levels with 3 replications for each treatment, as a factorial based on completely randomized design for super strain b tomato cultivar. the...

materials and methods: 32 new zealand rabbits were randomly divided into three groups: control group, high-cholesterol group and losartan group. the level of weights, serum lipid levels and inflammatory factors, such as il-6 and hs c-reactive protein were detected before the losartan intervention and two months after the losartan intervention respectively. the content of angii was detected on l...

in the water-limited areas, the great challenge of the agricultural sector is more production from less water that it can be achieved by increasing water productivity. a field study was conducted to compare various cultivars of wheat to water using line source sprinkler irrigation at gorgan research station in 2005-2006. the effect of variable water supply on yield and wue of six wheat cultivar...

quality and flesh colour characteristics of blood oranges following harvest is related to and dependent upon temperature and storage conditions. to investigate the effects of different temperatures (8, 15 and 22ºc) and different storage period (0, 25, 50 and 75 days) on total soluble solids, titrable acidity, ph, ascorbic acid, total phenolic contents, antioxidant capacity, anthocyanin level, a...
