in this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. experimental research was conducted on a laboratory apparatus. corn was used as a material because of its significance in agriculture and the food industry. an analysis of the influence of the operational parameters (the drying medium velocity i. e. the fluidization number, the drying me...

[1] The partial fluidization model developed by Aranson and Tsimring (2002) is used to simulate the spreading of a 2D circular cap of granular material over an erodible bed made of the same material. Numerical results show that the presence of even a very thin layer of granular material lying on the solid bed strongly increases the mobility of granular flows. Furthermore, as the thickness of th...

a series of novel 2-aminopyrimidine and 2-substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against adp and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. none of the compounds showed satisfactory activity against the aggregation induced by adp. however, satisfac...

the existing studies of threshing process of combine harvesters adopt the assumption of constant mass, which is contradictory to the phenomenon of separation of grains and short stalks in actual threshing process. therefore, the characteristics of threshing and separation are not accurately described. aiming at this problem, this study established the tangential-longitudinal threshing and separ...

The thermal stability of the machining centers plays a major role in ensuring production repeatability. All machine tools producers take various steps to ensure it. One ways permanently maintain and stabilize behavior tool is use active cooling choice appropriate material which individual parts supporting system are made. In most cases, manufacturers traditional metallic materials (steel, cast ...

Clinoforms on coasts exposed to ocean waves form from sand exported from the shoreface during extreme wave conditions and deposited where wave action diminishes. Elsewhere, it is shown that, during upper 5-percentile wave conditions, wave-induced shear stresses exceed the sediment threshold of motion to below the clinoform rollovers. Experiments and theory suggest that, where bed sediments are ...
