a total of 332 birds including 149 sparrows, 147 doves and 36 pigeons were examined for toxoplasma infection by both direct agglutination for detecting antibodies to toxoplasma and direct parasitological test to detect the cyst of toxoplasma in the brain of birds. the toxoplasma sero-positive rate (spr) in the examined birds was 10.5 percent (27 cases) with titers of 1:40 or higher and spr in e...
In this paper experimental analysis of ballistic limit velocity of autoclaved aerated concrete (AAC) targets under rigid projectile penetration is presented. Industrial blocks with dimension of 600*250*200(mm) were cut into 125*125*50(mm) samples, impacted by gas gun using three different nose shaped projectiles (flat, ogive and conic). In this study damage mechanism and penetration depth were ...

In this paper, SiO2 thin film is produced by two methods: at the first method, SiO2 is evaporated by the electron gun and oxygen gas is injected to compensate for oxygen loss due to dissociation. At the second method, silicon monoxide is evaporated by thermal evaporation and during the evaporation time, substrate is bombarded by the ion oxygen that produced by an ion source. The refraction inde...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
the present article surveys the personality and the life of mohammad maghout and studies and analyzes the play of the hunchback sparrow in regards to the form and content. mohammad maghout is one of the most prominent poets and writers from syria in the temporary century. such a personality is worth to be studied through his works to understand his concerns and thoughts.
Every synchrotron accelerator requires a pre-injector for primary injection of the electrons into the booster ring. The Iranian Light Source Facility (ILSF) pre-injector is a 150 MeV S-band linear accelerator with a thermionic cathode RF gun. The design of the pre-injector lattice and its beam dynamics calculation results together with the design of RF gun, alpha magnet, quadrupole magnets and ...
The dynamic fracture of a body is a late-stage phenomenon typically studied under simplified conditions, in which a sample is deformed under uniform stress and strain rate. This can be produced by evenly loading the inner surface of a cylinder. Due to the axial symmetry, as the cylinder expands the wall is placed into a tensile hoop stress that is uniform around the circumference. While there a...
