this experiment was conducted to determine the ame, amen, tme and tmen of beet pulp fed to male ostriches at  their 90 d of age. different levels of beet pulp (0, 15, 30 and 40%) were fed through replacements in the basal diet. for a determination of ame and amen using marker method, beet pulp was replaced in the basal diet at 40%. a number of 16 vs. 8 ostrich chicks were employed in each of th...

background: introducing rctm (research-centered teaching method) by the author, showed the method provokes enthusiasm and anxiety, correlated with cognition . by linking the broaden-and-build theory and emotional intelligence theory, it becomes apparent that the knowledge and use of positive emotions constitute an important skill set for effective functioning. purpose: to investigate the effect...

in this study 50 samples of ecstasy tablets seized in iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. in order to determine the chemical characteristics of these tablets, color tests (marquis test, simon’s test, chen’s test and gallic acid test), thin layer ...

for designing tillage implements it would be better to estimate soil forces exerted to the implements. many researches showed that numerical method of discrete element method (dem) is the cheapest and fastest technique for modeling granular material such as soil and especially sandy soil. in this study, paraplow and bentleg tines performance was compared with conventional tine using experimenta...

melamine trisulfonic acid (mtsa) as an efficient heterogeneous catalyst has been used for the one-pot preparation of triazolo[1,2-a]indazole-1,3,8-trione and 2h-indazolo[2,1-b]phthalazine-1,6,11-trione derivatives by the three-component condensation reaction of urazoles or phthalhydrazide, dimedone or 1,3-cyclohexanedione, and aldehydes under solvent-free conditions in good to excellent yields ...

bitter asafetida (ferula asa-fetidae l.) is a wild plant of the family umbelliferae. the present study was carried out to determine the type of dormancy of the plant’s seed, and find out the most suitable treatment needed for quick germination of seeds. twelve treatments including ga3 (500, 1000, 1500 ppm), kno3 (0.1, 0.2 0.3 molar), rinsing (24, 48, 72 hour),elimination of seed coat (one year-...

1-carboxymethyl-3-methylimidazolium chloride {[cmmim]cl} is utilized as a highly efficient and reusable catalyst for the synthesis of bis(indolyl)methanes by the condensation reaction of indole with arylaldehydes under solvent-free conditions at room temperature. in summary, the presented method have several advantages including simplicity, low cost, generality, efficiency, clean reaction profi...
