In this experiment, different doses of Zataria multiflora (ZM) and Eucalyptus globolus (EG) essential oils (EOs) (0, 100, 250, 500, 750 and 1000 µg/mL) and a mixture of them were added to alfalfa hay incubated with buffered rumen liquor of Merghoz goat to assess in vitro gas production, rumen fermentation and protozoa population. In all treatments the asymptotic gas volume (B) and the rate cons...
The study was designed to determine the effect of a candidate natural feed additive on kinetics gas production as representation degradability and methane produced during rumen fermentation. Three blends essential oil (BEO) candidates for additives were formulated using pine eucalyptus oils in following ratios: 75:25, 50:50, 25:75 BEO1, BEO2, BEO3, respectively. Every BEO added batch fermentati...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
a structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. the model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-batch r...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
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...
in this work, experimental kinetics data of methane hydrate decomposition at temperatures ranging from 272.15 to 276.15 k and at pressures ranging from 10 to 30 bars were modeled by using chemical affinity. this model proposed a macroscopic model which is independent of any intermediate mechanism like heat or mass transfer. the results show there is good agreement with experimental data. also t...
introduction using agro-industrial by-products in ruminants feeding could help in semi arid climate condition throughout the year. raisin by-product is produced in huge magnitude in malayer city, hamedan province. local different raisin by-products which produced during machinery cleaning and sorting of sun dried treated grapevine cluster (vitisvinifera l. cv. sultana), are as:1) some outer lay...
