1- in a search directed to the reaction of compound)23(the cycloaddition reaction of 1,3- diphenylisobenzofurane)14(with p-benzoquinone)19(,followed by addition of cyclopentadiene was carried out.the specific spacial stracture of its ir,nmr,mass spectra. 2- in another attempt the kinetic stability and behavior of compounds)20(and)23(was studied.the main subject of this study was the highly reve...
the aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of romanian simmental dairy cattle. for the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
the aim of this study was to estimate genetic parameters of age at first calving and its relationship with productive traits of holstein dairy cows. a total of 24491 first lactation records (2x 305d) which were collected from 1995 to 2009 were used. the general linear model (glm) procedure was applied to determine effective factors on studied traits. herd-year-season (hys) and age at first calv...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
The breeding value was estimated from grade Holstein Friesian for milk yield at 305 days (305MY), percent fat (FP), and total fat yield (FY) in kilogram. Animals were raised under Thai small farm conditions each of 10 to 30 heads per household. The data were collected during the years 1972 to 1998 from the joint cooperation between Kasetsart University (KU) and the Dairy Farming Promotion Organ...
possibility of replacing whole soy flour for chocolate fat in chocolate production and its impact on textural, rheological and sensory properties of low fat chocolate was explored. for doing this, whole soy flour in 5 levels (0, 2,4,6,8 percent) and two refining times (105 and 135 minutes) was employed. results indicated that longer refining time gave rise to reduction in particles size and inc...
The aim of present study was to estimate genetic and phenotypic trends for body weight traits at some ages in Lori-Bakhtiari lambs. In this study a total of 7721 records on birth weight, 6462 records of one month weight, 7275 records of weaning weight 5745 records of 6 month weight, 3326 records of 9 month weight and 3088 records of 12 month weight of Lori-Bakhtiari sheep was used to reveal the...
In this study, estimation of genetic parameters of Lameness and genetic and phenotypic correlations between Lameness and milk, fat and protein yield were performed. The data obtained from 63403 Holstein cows were collected from the Animal Breeding Center of Iran between 2001 to 2013 Estimation of genetic parameters for lameness was performed by univariate animal and Threshold models. Also, esti...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
