Material selection is a challenging issue in manufacturing processes while the inappropriate selected material may lead to fail the manufacturing process or end user experience especially in high-tech industries such as aircraft and shipping. Every material has different quantitative and qualitative criteria which should be considered simultaneously when assessing and selecting the right materi...
This experiment was conducted to determine the effect of selection index in four iranian commercial silkworm lines (107, 110, 153, 154) on resistance of their hybrids including 107×110, 110×107, 153×154, 154×153 under stress of nuclear polyhedrosis virus (N.P.V) Infection. Selection index program was performed on 3P commercial lines during 9 generations. Later generation parents of 3P lines wer...
In this study, 14322 growth trait records of 2387 sheep bred and reared in the Rearing and Breeding Station of Bakhtiari Sheep during 1989-1997 were used to estimate the phenotypic, genetic, and environmental trends for some of the growth traits using Animal Model for lambs, rams, and ewes. The genetic trend of birth weight, weaning weight, six month's weight, daily gain from birth to weaning, ...

drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...
Full-sib family selection for rate (WP) or efficiency (WP/F) of protein gain in rats from 3 to 9 weeks of age was applied for five generations. Three rats per litter were killed to estimate carcass protein. Standardized response/cumulative selection for WP was .19+/-.10 for WP, .28+/-.10 for 3- to 9-week gain .28+/-.08 for 9-week weight, .16+/-.08 for litter size, .22+/-.12 for skinning loss an...
in this study, 100 moghani sheep from breeding station located in jaafarabad, moghan were genotyped for exon 1 of igf-i gene, using pcr-sscp. different band patterns were obtained in this site gene that was studied. based on sscp patterns, three genotypes bc, bd and bb obtained with frequencies of 65%, 26% and 9%, respectively. the genotype frequencies had a significant deviation from hwe. in a...
Direct and Correlated Responses of Selection in Divergent Selection for Intramuscular Fat in Rabbits
The objective of this study was to evaluate the genetic response for a divergent selection experiment on intramuscular fat (IMF) content and to estimate the correlated response in carcass and meat quality traits. Data from two generation of selection were used in this study. The base population was composed of 13 males and 83 females. High (H) and Low (L) lines had 8 males and approximately 40 ...
An important application of DNAmicroarray data is cancer classification. Because of the high-dimensionality problem of microarray data, gene selection approaches are often employed to support the expert systems in diagnostic capability of cancer with high classification accuracy. Penalized logistic regression using the least absolute shrinkage and selection operator (LASSO) is one of the key st...
