We compared the conventional atomizing disc aeroponic technology with the latest ultrasonic nebulizer technology for the production of Glomus intraradices inocula. The piezo ceramic element technology used in the ultrasonic nebulizer employed high frequency sound that blasted the nutrient solution and nibulized it into micro-droplets size of 1μm in diameter. Growth of the pre-colonized AMF-root...

Dust control tests of experimental enclosed layer and floor feeding broiler houses were performed with ultra sonic sprayer units which have some advantages such as 1) low cost, 2) low electric power consumption, 3) forcing the charge and 4) unnecessary to lay pipes to spray. With spraying 2 % solution of emulsified canola oil in layer house, the concentration of dust with aerodynamic diameter (...

Abstract The transonic phenomenon of black hole accretion and the existence photon sphere characterize strong gravitational fields near a horizon. Here, we study spherical flow onto general parametrized spherically symmetric spacetimes. We analyze process for various perfect fluids, such as isothermal fluids ultra-stiff, ultra-relativistic, sub-relativistic types, polytropic fluid. influences a...
