1. introduction isfahan oil refinery (isfahan, iran) is responsible for the production of huge amounts of oil waste. as the released organic compounds are highly toxic, carcinogenic, and mutagenic, they can potentially contaminate the soil and groundwater resources of the adjacent area. this is particularly important in isfahan where arid/semi-arid climate has limited the access to adequate sur...

background and purpose     methods:     results:     conclusion:

insect natural enemies selected for such specific traits as faster developmental times, longer survivor, increased fecundity, and larger body size might be considered during production of biological control agents in certain situations. for instance, traits related to developmental rates may be selected for, if genetically based variation exists within temperature-dependent responses. hippodami...

the effects of replacement of alfalfa hay with pistachio by-product (pb) at 0, 25, 50, and 75% (dm basis) on the ruminal parameters, dry matter intake (dmi) of female rayini goats, after kidding, and on the live weight gain (lwg) of their kids were investigated. five single-bearing female rayini goats each with a single kid were employed in each level of replacement. the basal diet contained ba...

effects of different amounts of morning liming on blood ionic parameters and blood biochemical parameters of cultured carp ponds in dikjeh area of gonbad were investigated. 9 ponds (3 hectars) were chosen and divided in 3 treatments (1- liming 750 mg/l, 2- liming 1250 mg/l, 3- liming 1750 mg/l). liming had significant effect on blood hematocrite (p0.05) were observed between other blood paramet...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...

to compare the nutritional value of rapeseed meal and cottonseed meal in holstein cows, feeding 20 lactating holstein cows each with an average weight of 580± 34 kg and 100± 10 days in milk were studied in a randomized complete block design. the experimental diets consisted of 4 levels of 0, 8, 14 and 25 percent rapeseed meal replaced with cottonseed meal and barley grain in the diets. diets we...

a study was carried out to examine the effect of different levels of herbal methionine and dl-methionine on the growth performance and immunocompetence of broiler chickens fed on a corn-soybean meal diet. a total of 225 old male broiler chickens (ross 308) were used as experimental samples in a completely randomized design. they were randomly assigned to 9 treatments each of 5 replicates in eve...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...

background: mesenchymal stem cells (mscs) are multipotential cells and their therapeutic potency is under intense investigation. studying the effect of different induction factors on mscs could increase our knowledge about the differentiation potency of these cells. one of the most important sources of these factors in mammalian body is platelet. platelet lysate (pl) contains many growth factor...
