After our studies on the distribution of water, nitrogen and electrolytes in the whole skin, it was thought that the different layers of the skin should be investigated separately. The epidermis was therefore separated from the corium and the nitrogen and electrolyte distribution was determined in each of the layers In view of the fact that adequate literature on the methods for the separation ...

Selection of mobile phases markedly affect separation efficiency of eluted probes in gas chromatography (GC), the mobile phases have a pronounced effect on the retention times and efficiency of natural gas separation. In solid chromatography, carrier gases which are adsorbed to any extent occupy more active adsorption sites, reducing the net heat of adsorption of the eluted zone. The efficiency...

Non-negative Matrix Factorization (NMF) has already been applied to learn speaker characterizations from single or nonsimultaneous speech for speaker recognition applications. It is also known for its good performance in (blind) source separation for simultaneous speech. This paper explains how NMF can be used to jointly solve the two problems in a multichannel speaker recognizer for simultaneo...

Nitrogen is very difficult to remove from natural gas. Most specifications require no more than 4% nitrogen or total inerts in the interstate pipeline system. With about 15% of the raw natural gas produced in the United States having nitrogen contents over 4%, technology is needed to economically bring the gas to pipeline quality. Cryogenic distillation, the current state-of-the-art technology,...

The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...
