If soil hydraulic conductivity or water holding capacity could be measured with a small volume of samples, it would benefit international fields where researchers can only carry limited amount soils out particular regions. We performed pinhole multistep centrifuge outflow method on three types soil, which included granite decomposed (Masa soil), volcanic ash (Andisol and alluvial clayey (paddy ...

In the first part of this thesis the means are described by which an industrial disc stack centrifuge may be scaled-down to process in a meaningful fashion small volumes of particle suspensions. The centrifuge separation characteristics so measured were suitable for direct scale-up predictions of centrifuge performance. Experiments with a dye tracer and a reduced number of discs indicated that ...

Centrifuge shaking table tests were conducted to evaluate damage level of embankments before sliding failure. In the test series, high-resolution digital images model obtained and strain distributions inside calculated using a PIV technique. Results showed that in embankment failure can be evaluated from material near its toe stress-strain relationship material. Finally, we propose performance ...

a simple and sensitive method is described for the pre-concentration by cloud point extraction followed by atomic absorption spectrometric determination of copper ion in real samples. at a solution ph of 5.5, 5, 5-diphenylimidazolidine-2, 4-dione (phenytoin) (dfid) and tritonx-114 were used as hydrophobic ligand and non-ionic surfactant. the adopted concentrations for dfid, triton x-114 and hno...
