During the past decade, pond aeration systems have been developed which will sustain large quantities of fish and invertebrate biomass. Dissolved Oxygen (DO) is considered to be among the most important water quality parameters in fish culture. Fishponds in aquaculture farms are usually located in remote areas where grid lines are at far distance. Aeration of ponds is required to prevent mortal...

Of all the fossil fuel sources, Coal Bed Methane (CBM) is least expensive for its energy content. This study aimed at assessing geological factors that may be responsible gas emplacement in Nigerian coal and syngas extraction using a locally fabricated gasification plant. Trace element, sulfur content, XRay diffraction, Scan Electron Microscope analysis of samples from Ute Okaba were carried ou...

Purpose Valsalva hemorrhagic retinopathy is a form of preretinal hemorrhage that develops after a valsalva maneuver, leading to rupture of the superficial retinal capillaries. Here, we report a case of valsalva retinopathy secondary to blowing a conch, the first case report of its kind. The patient blew conch, which was part of his daily ritual to pray to God as he was a Hindu priest. Observa...

We investigate pneumatic non-prehensile manipulation (i.e., blowing) as a means of efficiently moving scattered objects into target receptacle. Due to the chaotic nature aerodynamic forces, blowing controller must (i) continually adapt unexpected changes from its actions, (ii) maintain fine-grained control, since slightest misstep can result in large unintended consequences (e.g., scatter alrea...

The use of a scanning Light Detection and Ranging (LIDAR) system to characterize drift during pesticide application is described. The LIDAR system is compared with an ad hoc test bench used to quantify the amount of spray liquid moving beyond the canopy. Two sprayers were used during the field test; a conventional mist blower at two air flow rates (27,507 and 34,959 m3·h(-1)) equipped with two ...

The issue of the equivalence physical parameters working medium in heat-treatment zone fish and meat products is solved by organizing uniform high-speed fields area, which ensured corresponding design. aerodynamic characteristics a double-sided centrifugal blower fan with vertical arrangement drive shaft spiral scroll two outlet openings, outlines were carried out according to design square rul...
