Diversifying business activities on farm, primarily through agritourism, increases farm's helps reduce financial problems. Yet, importance consequently cultural social consequences areas have not be...

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...

this study was carried out to evaluate empirical models of competition, as two separated experiments based on a randomized complete block design with 3 replications at agricultural faculty of bu-ali sina university, in 2008-2009. in both experiments, alvand and sayson cultivar were planted with densities of 450 plants m-2. in the 1st experiment, feral rye (secale cereale) with densities of 0, 2...

in order to study adapatability and yield stability of irrigated bread wheat cultivars alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya this experiment was conducted in rcbd during three cropping seasons (2007-2010) in six cities. simple anova and combined analysis of variance for three years in every location and also combined analysis of variance for three years and six loc...

BACKGROUND The gastrointestinal cancers are among the most common cause of cancer-related death and their long term survival is very low. This study was aimed to determine the effective factors on survival of gastrointestinal cancers among Iranian population during 5 years of follow up. METHODS In total, 157 patients diagnosed as gastrointestinal cancers from 2007 to 2009 in the only center o...

BACKGROUND This study was conducted to determine if serum inhibin B concentration can predict spermatogenesis in azoospermic infertile men. METHODS This cross-sectional study included 70 patients with male-factor infertility referred to Alvand and Vali-e-Asr Infertility Centers, Tehran, Iran. All patients had azoospermia. Standard evaluation consisted of history and physical examination with ...

Existing fossil fuels do not meet the needs of modern societies and are almost coming to an end. Hence, governments can respond both to the needs of the people and the industry, by investing in the use of renewable energies. As well as saving fossil fuels, natural gas and even water. According to the research, renewable energy, especially wind energy, has been used in recent years and are able ...

Drought hasunfavorable impacts on the success of agriculture in many parts world.Providing future populations with enough food would obviously require evaluation crop yield, higher potentials, and provision yield stability drought-affected regions. In this research, drought-tolerance wheat genotypes was studied a randomized complete block design three-replication experiment under normal drought...

introduction hydrograph of springs represents clearly all physical processes that control ground water flows inside aquifer (kuto et al., 2012: 41). study of the curve can reveal information about structure and function of aquifer, particularly hydrodynamic parameters including permeability and storage (troch et al., 1993: 228). analysis of recession curve has the advantage to calculate paramet...
