An experimental investigation of the phosphorescence properties of liquid and vapour acetone is presented with the goal of introducing a novel technique for improved two-phase flow visualization. Commonly applied laser induced fluorescence (LIF) investigations of two-phase flows are challenging, in particular because of the large disparity in fluorescence intensity between the two phases and th...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
We found that with oral supplementation by a liquid soy-based protein hydrolysate in malnourished COPD patients (BMI <= 20), it possible to increase weight over a 6-week period, and body water and an index of muscle mass (MAMC), but not total body nitrogen (TBN judged by Nitrogen Index) which identifies a particular challenge for nutrition support in COPD patients. There was no associated impro...
The ponderomotive force, exerted upon all dielectric liquids by a non-uniform electric field, can be used for the remote, voltage-controlled manipulation of 10 to 100μL volumes of cryogenic liquids. This liquid dielectrophoretic (DEP) effect, imposed by specially designed electrodes, combines with capillarity to influence the hydrostatic equilibria of liquid deuterium. A simple, one-dimensional...
