When the stagnation temperature of the combustion chamber or ambient air increases, the specific heats and their ratio do not remain constant any more, and start to vary with this temperature. The gas remains perfect, except, it will be calorically imperfect and thermally perfect. A new generalized form of the Prandtl Meyer function is developed, by adding the effect of variation of this temper...

For bounded linear operators defined on complex infinite-dimensional Banach space, H. Zariouh, in an article [1] introduced and studied the property (gaz). In this study, through techniques using local spectral theory of operators, we discover sufficient conditions that allow transfer (gaz) from two tensor factors T S to their product T⊗S. The stability under perturbations is also investigated....

in order to identify flora and distribution mapping of weeds in citrus orchards of bandar-e-gaz township, 101 orchards were selected during 2014, and the summer weed species were sampled and detected using a w method. with using specific formula of density, frequency, uniformity, abundance of each weed species was calculated. also, geographic coordinates of orchards (latitude, altitude and elev...

fluoride is an essential element for human health. however, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. drinking water is the main route of fluoride intake. the aim of the present study was to measure fluoride levels in human breast milk collected from two regions of golestan province, northern iran with different amount of fluoride concentration of drinking wa...
