The Voronezh region is traditionally the most important area of crop production and farming. purpose study was to contamination by heavy metals medicinal vegetable raw materials on example grass five-plant desert collected in urban agro-ecological systems, which experience different anthropogenic effects. accumulations (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) arsenic wer...

ABSTRACT: This work investigated the thermal treatment to separate and concentrate economically valuable materials from laminates of crystalline silicon photovoltaic modules (i.e., without aluminum frame junction box). Chemical characterization metal content was performed by X-Ray Fluorescence (XRF). The polymers backsheet were also characterized Fourier Transform Infrared Spectroscopy (FTIR). ...

The use of geometallurgical modelling is becoming common in the design a concentrator plant and during its operational phase. Predictive aims to define optimized process parameters for accommodate variability ore feed characteristics. main objective this study simulate metallurgical response distinct unit types their blends using kinetic models derived from experimental flotation tests. Kinetic...

Zinc and lead are the two most widely used non-ferrous metals after aluminium and copper as vital materials in everyday life. They are mined and smelted in many countries in both the developed and developing world. Both pyrometallurgical as well as hydrometallurgical methods are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical pro...

Cultivation of poppy as a source of opium alkaloids for legitimate medical purposes has a long tradition in Turkey. The main products are poppy straw and concentrate of poppy straw, obtained from dried poppy capsules. The aims of the study reported in the present article were to establish inorganic element profiles for the poppy-growing provinces of Turkey by means of x-ray analysis by scanning...

ABSTRACT- Considering health and economic issues, today, consumers have become more concerned with foods which contain natural ingredients. Hence, in this study, the effects of plum concentrate and puree which were incorporated into the Taftoon bread formulation at different levels on the rheological, baking properties and shelf life of bread were evaluated. Results showed that addition of plum...

The study investigated the dietary impact of 18:3n-3 vs. 18:2n-6 on fatty acid- and micronutrient concentration of beef muscle and the extent of diet- and processing-induced changes of lipid- and micronutrient concentrations of beef products made thereof (German Corned beef (GCB), tea sausage spread (TSS), scalded sausage (SS)). Beef and beef products were obtained from German Holstein bulls wh...

This current study addresses the role of copper and aluminum - typical major components collector scrap from battery manufacturing plants in leaching pre-treated LiCoO2-rich waste concentrate at industrially relevant process conditions (T = 60 °C, [H2SO4] 2 M, S/L 200 g/L). An empirical model has been constructed which demonstrates that effects both are significant. Both elements have independe...

Dietary advice and intervention clearly have a place in rheumatology and allow patients to have some control over their own disease. Although there is no evidence for efficacy of 'fad' diets, 30-40% of rheumatoid patients can benefit from excluding foods individually identified during the reintroduction phase of an elimination diet. A proportion of patients who follow a vegetarian or Mediterran...
