the world wide web becomes very popular recently and plays an influential role in english learning. by burgeoning role of source-based writing as partial fulfillment of tefl courses and vast use of the internet, lack of empirical studies to explore these areas is obvious. this study aimed to explore the effect of the amount of familiarity with the web (internet literacy) on junior english stude...
the present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of bovan neva black laying hens at 25, 51 and 72 weeks. for this purpose, thirty birds were selected from the layer flock in the babcock university teaching and research farm. they were individually housed in separate labeled battery cage. a total of thirty eggs were collected...
To study relationship between grain yield and important agronomic traits of rapeseed in paddy fields as second culture, fourteen varieties of spring rapeseed were grown in a randomized complete block design of experiment with three replications at Rice Research Institute of Iran, Rasht, during 2005-2006. Analysis of variance showed that there were significant differences between varieties for m...
the possibility of in vivo carcass trait prediction using the ultrasound measurements obtained between 12th and 13th ribs was studied. attention was paid to several carcass traits such as carcass backfat thickness (cbft), carcass longissimus dorsi muscle (clma) and carcass weight (hcw). also, the effects of the flock, as the fixed effects, and body weight (bw), as covariate, on these traits wer...
objective: estimation of genetic parameters for kleiber ratio (kr) and genetic trends for pre-weaning weights of arabi sheep has not been previously conducted.methods: data and pedigree information were collected at the khuzestan ramin agricultural and natural resources university, animal science research station, located in southwest iran, from 2001 to 2008. (co)variance components and corresp...
The objective of this study was to quantify the genetic variation in carcass cuts predicted using digital image analysis in commercial cross-bred cattle. The data set comprised 38,404 steers and 14,318 heifers from commercial Irish herds. The traits investigated included the weights of lower value cuts (LVC), medium value cuts (MVC), high value cuts (HVC), very high value cuts (VHVC) and total ...
records of 2593 baluchi ewes, obtained from baluchi sheep breeding station in abbas abad, mashhad, were used to estimate genetic parameters for total weight of lamb weaned per ewe joined (tww/wj) in different parities. estimates of heritability for tww1/ej, tww2/ej, tww3.ej and tww4/ej were 0.112 ? 0.030, 0.028 ? 0.030, 0.075 ? 0.060 and 0.135 ? 0.120, respectively. direct additive genetic corr...

abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
________________________________________________________________________________ Abstract The objective of the study was to estimate genetic and phenotypic parameters for sow productivity traits of South African Large White pigs, using data from the Integrated Registration and Genetic Information Systems. The analyses were done on 29 719 records for 7 983 sows from 29 herds, which farrowed betw...
