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...

to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...

alkylation of biphenyl with 1-octene was investigated using ((al+c3h7cl)+c2h4) catalysts. the catalytic activity of ((al+c3h7cl)+c2h4) for the alkylation was studied at different temperatures, mol ratios of biphenyl to 1-octene, reaction times and catalyst concentrations. it was shown that using this catalyst has more advantagous than another catalysts. experiments show that by increasing tempe...

background: during antigen capture and processing, mature dendritic cells (dc) express large amounts of peptide-mhc complexes and accessory molecules on their surface. dc are antigen-presenting cells that have an important role in tolerance and autoimmunity. the transforming growth factor-beta1 (tgf-β1) cytokine has a regulatory role on the immune and non-immune cells. the aim of this study is ...

effect of foliar spraying by humic acid on mineral leaf composition, yield and fruit quality of apple (malus domestica l. cv. ‘granny smith’) was studied. an experiment based on randomized complete design was conducted in khorramdare city of zanjan province. spraying of humic acid was conducted in four levels 0, 5, 10 and 15 mg/l on eight year-old ‘granny smith’ apples grafted on mm106 rootstoc...

background and purpose: future generalists require in depth exposure to primary care practice and the opportunity to work with successful generalist role models.changes in hospital practice, patient availability, increased student numbers and their expectations and a redefinition of expected learning outcomes are changing the emphasis of clinical teaching away from traditional inpatient setting...

the current experiment was carried out to investigate the possible effects of replacing alfalfa by dried de-oiled savory (satureja khuzistanica; dds) at the levels of 0, 25, 50, 75 and 100 percent in finishing diets of mehraban lambs on kinetics of gas production in vitro. the experimental diets contained 20% alfalfa and 80% of concentrate on dry matter basis. replacing alfalfa by dds had no si...

to evaluate the effects of methanol and drought stress on chlorophyll fluorescence parameters, chlorophyll and relative water content in sugar beet, a study was conducted in 2008 in maahdasht (karaj, iran). aqueous solutions of 0 (control), 7, 14, 21, 28, 35% (v/v) methanol with each solution containing 0.2% glycine and a second factor, namely drought stress (irrigation after 70% depletion of a...

an investigation of chlorophyll quick fluorsence variations was made in the reaserch field of islamic azad university- karaj in 2007. the experimental design was a split plot one in form of a complete randomized block design with 4 replications. drought stress was cosiderded in three levels of 40%, 60%, and 75%, on the basis of depletion of soil moisture as the main factor and the factor of mic...
