in this research genetic and phenotypic parameters were estimated using linear and threshold models, for reproductive traits, data from 6 large industrial dairy herd of east azerbaijan province collected by agriculture jihad organization during 10 years (2001-2010). best linear unbiased predictions of traits breeding values were estimated using restricted maximum likelihood method by wombat sof...

in this paper, a two-dimensional reynolds averaged navier-stokes (rans) model is developed to simulate the shoaling, breaking and overtopping of a solitary wave over a vertical breakwater. turbulence intensity is described by using a k turbulence closure model and the free surface configuration is tracked by volume of fluid (vof) technique. to validate the numerical model the simulation result...

abstract a significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. this research presents a straightforward approach for processing output of the hec-ras hydraulic model, to enable two- and three dimensional flo...

while many researchers devoted numerous articles to the organizational culture, relatively few articles have been contributed to culture and performance research. the purpose of this study is to shed light on the role of organizational culture on performance. to achieve this goal and in order to measure organizational culture, denison organizational culture model was used. the components of thi...

among various reported membrane-based gas separation processes, the best explanation is generally achieved by the solution-diffusion model. the main factors in this model are the solubility and diffusivity of permeationcomponents through the membrane. the prediction of permeability and diffusivity in multicomponent gas permeation as well as the separation evaluation equilibrium and kinetic inte...

liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 k. the studied systems exhibit two types of liquid-liquid equilibrium (lle) behavior. the system consisting of benzyl alcohol displays type-1 lle behavior, while a type-2 behavior is exhibited by the other s...

abstract land surface hydrological models has importance in the determination of soil moisture and temperature, the rate of evapotranspiration, stream flow by emphasis on the land surface physical and dynamic process descriptions. in this research, vic land surface hydrological model has been used for the land surface temperature and stream flow determination. the vic runoff simulation in each ...

objective: poverty alleviation is an essential step to achieve economic development. this is why identification exercise is so crucial. traditionally, different aspects of insecurities have not be taken into poverty measurement. many types of insecurities have adverse impacts on household welfare. identifying vulnerability of household can serve identification of the poor households. methodolog...

objective: this study was conducted to investigate the effectiveness of education based of the cognitive, metacognitive, and behavioral model on the reduction of meta-worry beliefs in patients with social anxiety disorder (sad). methods: the research was a quasi-experimental study with pretest-posttest design and a control group. the statistical population comprised all patients with sad referr...

objective: the main objective of this research was estimation of genetic parameters for five consecutive measurements of egg weights in isfahan fowl using multi trait model and random regression models. methods: the statistical models included generation-hatch as a fixed effect, weeks of age as a covariate and additive genetic and individual permanent environmental effects as random effects. th...
