abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
We determined the effects of dietary supplementation of different doses of Miswak (Salvadorapersica) steam and leaf powder on the performance, blood parameters, cecal flora, and carcass traits of broilers. Four hundred and eight one-day old Ross 308 broiler chicks were provided one of the following experimental diets over 42 days: a basal diet without any additives, or a basal diet supplemente...
This experiment was conducted to investigate the effects of different sources of zinc on performance, egg quality, and immune system and blood parameters of Japanese laying quails. Total of 160 layer quails were allocated in 4 treatments include: 1) Basic diet as control, 2) Basic diet + 50 mg zinc/kg of diet from nano zinc oxide (n-ZnO), 3) Basic diet + 50 mg zinc/kg of diet from Availa-Zn as ...
This study was carried out to investigate the effects of Savory essential oil and Flavomycin on performance, some carcass traits, immune response and hematology of broiler chickens. In this research, four houndered Ross 308 male chicks were used in a completely randomized design with 5 treatments and 4 replicates and 20 broiler chicks per experimental unit. Experimental treatments consisted of ...
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
Records for daily feed intake during lactation were available for 774 sows with 2,234 litters farrowing from May 2002 to November 2006. Genetic parameters were estimated for whole-oflactation feed intake and feed intake averaged over 5-day periods during lactation. Estimates of heritabilities and the permanent environment of the sow were 0.16±0.05 and 0.18±0.04 for total lactation feed intake a...
this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...
This study was conducted to compare the feedlot performance and growth traits of Lori-Bakhtiari (n=39), Romanov × Lori-Bakhtiari (n=38) and Pakistani × Lori-Bakhtiari crossbred (n=12) lambs during two consecutive years. Lambs were weaned at the age of 90 ± 5 days. After weaning and preliminary fattening period, three groups of lambs were fattened for 90 days in the same conditions. The resul...
