this paper tries to survey irans regional labor market disequilibrium within 1996-2000. according to the results there has been an increase in the amount of disequilibrium of irans national as well as regional labor markets. incomplete labor market information on vacant job opportunities in different regions of the country along with high costs of migration have been the major causes of unemplo...
This paper discusses the environmental myths and narratives prevailing in Nepal in reference to the population growth and soil erosion. Soil erosion is taken as primary element of environmental degradation by the theory of the Himalayan Environmental Degradation (HED). Many myths and narratives were generated by the vested interest groups to develop the HED. Population growth and over exploitat...
We have found that shochu distillery by-product (SDBP) contains a growth promoting factor that can be extracted with ether. In the present study, we administered hexane-extracts of SDBP (HSDBP) to broiler chickens and observed changes in skeletal muscle protein degradation in order to clarify the mechanism of growth promotion due to SDBP feeding. The pectoralis superficial muscle weight was sig...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
We explore the hypothesis that because of their important role in collection activities related to environmental goods (firewood, water, grazing) the demand for children may increase with local resource depletion, setting up a vicious circle interaction between resource depletion and population growth. Using a large scale household data set from Pakistan with detailed information on female, chi...
Degradation is a common phenomenon for many products. Due to a variety of reasons, the degradation rates of units from the same population are often heterogeneous. In addition, when the degradation process is monitored using dedicated sensors, the measurements are often inaccurate due to various noisy factors. To account for the heterogeneous degradation rate and the non-negligible measurement ...
In the radio communications industry, one major problem is the vibration induced on to a frequency standard. The most commonly used frequency standard is the crystal oscillator; as the crystal oscillator gets vibrated with varying force and frequencies of vibration the phase noise of the signal changes. As the phase noise increases, the signal to noise ratio decreases causing the likelihood of ...
