in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
Two experiments were conducted to determine the effects of dietary NDF on apparent ileal and fecal digestibility and portal flux of nitrogen (N) and amino acids, and on N retention in growing pigs. In four equal portions (at 0600, 1200, 1800, and 2400) barrows on Treatment B received a basal diet, based on casein, cornstarch, and dextrose, at a feeding level of 2.6 times energy for maintenance....
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
Five common range forage including Agropyron intermedium, Bromustomentellus, Hordeum bulbosum, Cousinia bakhtiarica and Scariolla orientalis, weresampled during three phenological stages, from controlled rangeland stations over fivelocations in Chaharmahal and Bakhtiari province, Iran. All samples were chemicallyanalyzed for Crude Protein (CP%), in vitro Dry Matter Digestibility (DMD), OrganicM...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Covariance analysis limits error, the degree of nuisance variation, and overparameterizing factors to accurately measure treatment effects. Data dealing with growth, carcass composition, and genetics often use covariates in data analysis. In contrast, nutritional studies typically do not. The objectives of this study were to 1) determine the effect of feeding diets containing dehulled, degermed...
this experiment was carried out to investigate the effect of adaptation period to oak leave's tannin on rumen ph and ammonia, rumen microbial population, gas production and dry matter true digestibility (ivtdmd) in alamout goat’s rumen (with no previous history of oak leaf consumption) compared with markhoz goat (with previous history of oak leaf consumption). the goats were fed either oak...
Cross-linking of lignin to arabinoxylan by ferulates limits in vitro rumen digestibility of grass cell walls. The effect of ferulate cross-linking on dry matter intake (DMI), milk production, and in vivo digestibility was investigated in ad libitum and restricted-intake digestion trials with lambs, and in a dairy cow performance trial using the low-ferulate sfe corn mutant. Silages of 5 inbred ...
