Background: The energy crisis and climate change necessitate studying and discovering of new processes involved in the production of alternative and renewable energy sources. Very high gravity (VHG) fermentation is one such process improvement aimed at increasing both the rate of fermentation and ethanol concentration. The technology involves preparation and fermentation of media containing 300...

Higher concentration is beneficial for the Paste and Thickened Tailings (PTT) operation in metal mine. Partial paste thickeners are produced lower density underflow. Flocculated tailings intended to form a water entrapped network structure thickener, which detrimental underflow concentration. In this study, continuous thickening experiment was carried out ultra-fine tungsten study influence of ...

Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...

T SHOULD BE POSSIBLE to separate cells of different types by utilizing differences in their specific gravities. Centrifugation of whole blood against high density fluids has been successful, at least in part, in separating leucocytes from peripheral blood.15 Gum acacia3 and bovine albumin1’2’5 have been used in this manner, but the method has been criticized because of the cost and labor involv...

We consider brane-induced gravity model in more than one extra dimensions, regularized by assuming that the bulk gravity is soft in ultraviolet. We study linear theory about flat multi-dimensional space-time and flat brane. We first find that this model allows for violation of equivalence between gravitational and inertial masses of brane matter. We then observe that the model has a scalar ghos...

We study self-consistent cosmological solutions for an Einstein Universe in a graphbased induced gravity model. The graph-based field theory has been proposed by the present authors to generalize dimensional deconstruction. In this paper, we consider self-consistent Einstein equations for a “graph theory space”. Especially, we demonstrate specific results for cycle graphs. 1 Pre-history 1.1 Ind...

This paper studied the performance of a floor-supply displacement ventilation system using computational-fluid-dynamics (CFD). The experiment was carried out in a full-scale environmental chamber with a floor-supply system to obtain reliable flow information for the validation of a CFD program. The validated program was used further to evaluate the performance of the floor-supply displacement v...
