The aim of this study was using Bayesian approach via Gibbs sampling (GS) for estimating genetic parameters of production, reproduction and health traits in Iranian Holstein cows. Data consisted of 320666 first- lactation records of Holstein cows from 7696 sires and 260302 dams collected by the animal breeding center of Iran from year 1991 to 2010. (Co) variance components were estimated using ...

abstract government size plays a vital role in the economic development process. therefore, in this study, the existence of a non-linear relationship between government size and economic growth was investigated using the two-sector production function developed by ram (1986). the data, covering 44 years (1961-2005), were collected from the iranian economic information center. two classification...

This paper investigates a model where a manager gathers private information about the cost variables of his responsibility center. The owner then elicits the manager's information from a budgeting mechanism. If the manager has to acquire information before the budgeting stage, stronger production distortions relative to the standard adverse-selection situation arise. Moreover, the manager may e...

The efficiency of chemical energy production of a photosynthetic system can be strongly enhanced in the presence of metal nanoparticles. Two competing effects contribute to the photosystem efficiency: plasmon enhancement of photon fields inside the light-absorbing chlorophyll molecules and energy transfer from chlorophylls to metal nanoparticles. The first effect can lead to strong enhancement ...
