Abstract Optimization of extracting food products from plant raw materials using a mathematical model is suggested. The has been derived for the analysis pectin Jerusalem artichoke. Multistage anti-cyclic extraction, non-stationary diffusion initial element processed material in form plates considered. calculations take into account effect reverse solvent change, time drain solid phase, among o...

The influence of the degree grinding particles growing raw materials during electric discharge extraction on quality obtained extracts was studied. Each electro-discharge contributes to a part material, which is confirmed by granulometric analysis. particle size material should be controlled, since excessive results in cloudy, difficult clarify and poorly filtered. design chamber proposed, grou...

in this work, the solubility of nicotine extracted from tobacco leaves, found in the north of iran, in supercritical carbon dioxide has been measured. also the effects of pressure, temperature, extraction dynamic time, and the organic co-solvent on the amount of nicotine extracted from tobacco leaves have been investigated. it should be stressed that in order to reduce significantly the number ...

Introduction: In most orthodontic patients, mandibular 3rd molars are in early stages of calcification, and prediction of eruption status would be difficult during the course of orthodontic treatment. The aim of this study was to evaluate the effect of first premolar extraction with moderate anchorage on angular changes of third mandibular molar after orthodontic treatment. Materials & Methods...

Background and Aim: Full extraction is often accompanied by adverse functional and esthetic effects. Postponing tooth loss is the ultimate goal of dental care. Thus, knowledge about the reasons of tooth loss and the mean age of patients can help in de-signing preventive programs. The aim of this study was to evaluate the causes of full mouth extraction of teeth and the mean age of patients. Ma...
