This experiment was conducted to evaluate the effects of different levels (0, 2 and 4%) of canola oil and 2 levels of heat (1 and 2 time heated) on blood biochemical parameters of Japanese quails. This study carried out in factorial (3×2) experiment based on completely randomized design with 360 of Japanese quails in 6 treatments and 3 replicate for 35 of day. In this study, blood biochemical p...
مطالعه تاثیر زمان، دما، اسیدیته و غلظت اورهآز بر جذب و فعالیت آنزیم در رسهای سپیولیت و ورمیکولیت
Urease is one of the most important enzymes in nitrogen cycle. The clay particles (with high surface area) play an important role in the stability of these protein compounds (enzymes) against various environmental factors. In order to examine the interactions between urease with sepiolite and vermiculite, three in vitro experiments were conducted separately in a completely randomized design. Tw...
an investigation was carried out to study the effect of sole heat treatment and sole 1- methyl cyclo propine (1- mcp) as well as in combination on storage quality of strawberries. the factorial experiment was conducted using a completely randomized design of three replications. treatments included heat treatment at two levels (room teperature, 45°c for 3h) and 1- mcp at two levels (0, 1µl l-1)....

abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
abstract osmoreguolation is a physiological processes that plant cell uses to maintain water balance and it is generally caused by metabolite accumulation inside the cell. inoculated legumes by some drought tolerant sinorhizobium isolates helps osmoreguolation by increasing biological nitrogen fixation. in order to find some drought tolerant sinorhizobium isolates, 80 isolates were isolated and...
β-glucosidase is involved in the degradation of cellulose in soil and has the potential for monitoring biological soil quality. the objective of this study was to determine the effects of barley residue placement, burning, nitrogen fertilizer and tillage management on β-glucosidase enzyme after a period of 90 days. a field experiment was carried out based on a completely randomized design with ...
in order to evaluate of physiological traits, related to drought tolerance, an experiment was carried out in controlled condition. the experiment was conducted to assess the effect of drought stress on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in two tolerant genotypes (mcc392 & mcc877) and two susceptible genotypes (mcc68 & mcc448) were grown in drought stress (25% f...
