BACKGROUND Knowledge of linkage disequilibrium (LD) levels among different populations can be used to detect genetic diversity and to investigate the historical changes in population sizes. Availability of large numbers of SNP through new sequencing technologies has provided opportunities for extensive researches in quantifying LD patterns in cattle breeds. The aim of this study was to compare ...

Birth weight (BW), weaning weight (WW), 6-month weight (W6), 9-month weight (W9) and yearling weight (YW) of Kermani lambs were used to estimate genetic parameters. The data were collected from Shahrbabak Sheep Breeding Research Station in Iran during the period of 1993-1998. The fixed effects in the model were lambing year, sex, type of birth and age of dam. Number of days between birth date a...

In recent years, the use of offshore wind turbines has been considered on the agenda of the countries which have a significant maritime boundary due to more speed and stability of wind at sea. The aim of this study is to investigate the effect of wind turbulence on the aero-hydrodynamic behavior of offshore wind turbines with a monopile platform. Since in the sea, the wind turbine structures ar...

abstract in general, garmesh wind in rasht province increases the temperature by 9°c and reduces relative humidity by 47%. the direction of prevailing wind during the garmesh wind is southern and its average speed increases by 2 m/s to 5 m/s. the highest frequency of garmesh wind occurs at 09 and 12 utc in december and january. the occurrence of this phenomenon substantially increases the horiz...

in this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of iran. four stations in khuzestan- abadan, hosseyneh, mahshahr, and shushtar- are analyzed to determine the potential of wind power generation in this province. from the primary evaluation and by determining mean wind speed and also the weibull funct...

wind erosion climatic factor is a measure of climatic factors explaining the wind erosion erosivity. humidity and wind speed are climatic characteristics that must be considered as the erosion parameters. in this study, linear moment analysis (l-moments) and wind erosion climatic factor were used to evaluate the regional climate’s tendency effect on wind erosion in yazd province. wind erosion c...

abstract the whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into lk and hk types; hk allele is recessive to lk with a single gene inheritance. this polymorphism showed different behavior in different environment, which could be due to adaptation process. this research was conducted on the zel and kermani breed research station, which k...
