the aim of this study was investigating some blood parameters of blue-neck male ostriches (struthio camelus) with 4 months old after feeding a diet containing 3% sunflower oil for two months. in the morning, after about 12 h of fasting, some blood samples were collected from the wing vein of ostriches at the beginning and 60 days of study in department of animal sceince arak university . the pl...

With the retirement of the space shuttle near and rising fuel prices driving a demand for more efficient travel, alternative engine technology is being heavily researched. The scramjet, or supersonic combustion ramjet, has proven to be a promising development in reusable hypersonic transportation. Flight testing these engines, however, is very expensive and no scramjet flight has yet been recov...

Chunk parsing has focused on the recognition of partial constituent structures at the level of individual chunks. Little attention has been paid to the question of how such partial analyses can be combined into larger structures for complete utterances. Such larger structures are not only desirable for a deeper syntactic analysis. They also constitute a necessary prerequisite for assigning func...

Estimation is the process of determining a likely value for a population parameter (eg, the true population mean or proportion) based on a random sample. In practice, a sample is drawn from the target population, and sample statistics (eg, the sample mean or sample proportion) are used to generate estimates of the unknown parameter. The sample should be representative of the population, ideally...

Current strategies for the control of schistosomiasis are based primarily on chemotherapy but successful vaccination against infection has been also demonstrated in several host parasitic models. The present study was designed to assess the effect of vaccination with schistosomulae atte nuated by different doses of γ-radiation in mice challenged with S. mansoni cercariae regarding hepatic histo...

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 ...

In this paper, we introduce a new parameter, called inertia weight, into the original particle swarm optimizer. Simulations have been done to illustrate the signilicant and effective impact of this new parameter on the particle swarm optimizer.
