the objective of this study was to estimate variance components and genetic parameters for growth curve parameters in shall sheep. studied traits were parameters of brody growth model which included a (asymptotic mature weight), b (initial animal weight) and k (maturation rate). the data set and pedigree information used in this study were obtained from the animal breeding center of iran and co...

This study is focused on the development of a systematic computational approach which implements Genetic Algorithm (GA) to find the optimal rigorous kinetic models.A general Kinetic model for hydrogenolysis of dibenzothiophene (DBT) based on Langmuir-Hinshelwood type has been obtained from open literature. This model consists of eight continuous parameters(e.g., Arrhenus  and Van't...

the objective of this study was to estimate genetic parameters coupled with genetic and phonotypic trends for age at first calving (afc), open days(od) and milk yield(my) of first lactation in iranian holstein cows. records of reproduction and production for genetic evaluation from 1984 to 2005 for afc, od and my were 71736, 20126 and 20126, respectively. single and two-variable animal models w...

in this research, 6517 records, collected by khojir sheep breeding station (tehran, iran), during 1991 to 2011 were used to estimate genetic parameters of lamb survival in zandi sheep. genetic parameters were estimated using 16 different models of animal model, sire and threshold models using reml procedures. the aic criterion was used to evaluate the models. the effects in the most suitable an...

Conventional SOI DNAFET devices, being able to detect single-nucleotide polymorphisms, are simulated in a comprehensive approach. These devices can be fabricated in high-density arrays and offer advantages compared to optical detection methods. The influence of device parameters like doping concentration and the size of the exposed sensor area is investigated.
