the aims of this study were the comparative study of probiotic, acidifier,antibiotic growth promoters and prebiotic on activity of humoral immune and performance parameters of broiler chickens.500 one day old male broilers (308 ross strain) were divided into 5 groups: a, b, c, d and e. each group with equal numbers of male included 4 replicates (25 chicks per replicate). group a was as control ...

chukar partridge raising is a profitable business. new feed additives of plant origin may be an alternative to antibiotic growth promoters. this study was carried out to determine the effect of different levels of pistacia atlantica oil on performance and pathological conditions in chukar partridge. one-day-old chukar partridge chicks were assigned to three dietary treatments of 40 birds each. ...

In this paper, using vortex blob method (VBM), turbulent flow in a channel is studied and physical concepts of turbulence are obtained and discussed. At first, time-averaged velocities,  and , and then their fluctuations are calculated. To clarify turbulence structures, velocity fluctuations and  are plotted. It is observed that turbulence structures occupy different positions and move with con...

The purpose of this paper is to studying nonlinear k-ε turbulence models and its advantages in internal combustion engines, since the standard k-ε model is incapable of representing the anisotropy of turbulence intensities and fails to express the Reynolds stresses adequately in rotating flows. Therefore, this model is not only incapable of expressing the anisotropy of turbulence in an engine c...

The object of this study is to characterize the aero-thermal performance of a rectangular turbine blade cooling channel for gas turbines equipped with turbulence promoters, square section ribs, inclined at 45 degrees with respect to the main flow direction. With this aim, a P.I.V investigation of the flow field within an inter-rib space inside four cooling channel models has been done. The pres...

many recent studies have shown that glycosylation patterns of agaricus bisporus are similar to those of mammalians, so that this organism is a good candidate for the expression of glycosylated pharmaceutical protein. to achieve constant interested gene expression in all cells of the organism, proper promoter isolation is necessary. to isolate this promoter, pcr with specific primers was perform...

• The empty channel Electrocell Microflow Cell and MP perform similarly to their larger counterparts in literature. Turbulence promoters enhance mass transfer by a factor 1.4–1.5. Mesh electrodes greatly (between 2.1 2.8) Woven mesh result 5.7 6.7 times faster reaction rates. family of electrolyzers is set differently sized commercially available electrochemical flow reactors, suitable for scal...
