The state of North Rhine-Westphalia (NRW) is vital to the success of Germany’s energy transition, as it is the traditional center of Germany’s manufacturing and energy-intensive industries, such as metal production, basic chemicals, non-ferrous metals and paper. NRW’s long history and high concentration of energy-intensive industry operations is mainly due to the proximity of black coal and lig...

conclusions it can be concluded that gi complications in pregnant women using ferrous sulfate are mostly caused by physiologic changes of pregnancy rather than ferrous sulfate; therefore, it is not reasonable to stop using ferrous sulfate due to gi complications. results none of the gi complications were significantly different between the ferrous sulfate and placebo groups at 24th - 28th and 3...

Innovative separation and beneficiation techniques of various materials encountered in electrical and electronic equipment wastes (WEEE) is a major improvement for its recycling. Mechanical separation-oriented characterisation of WEEE was conducted in an attempt to evaluate the amenability of mechanical separation processes. Properties such as liberation degree of fractions (plastics, metals fe...

Abstract Additive manufacturing (AM) technologies are currently employed for the of completely functional parts and have gained attention high-technology industries such as aerospace, automotive, biomedical fields. This is mainly due to their advantages in terms low material waste high productivity, particularly owing flexibility geometries that can be generated. In tooling industry, specifical...

The roasting of sulphide ores and concentrates is often the first step in the production of metals or chemicals. In many processes, the production of sulphuric acid is viewed as a by-product, while in some plants production is an important economic factor. Regardless of the purpose, a pyrite roasting plant consists of mainly three plant sections: roasting, gas cleaning and sulphuric acid. With ...

this study deals with bioleaching of the low grade uranium ore of saghand mine in iran using a mixed culture of mesophilic bacteria (acidithiobacillus ferrooxidans, acidithiobacillus thiooxidans and leptospirillum ferrooxidans). experiments were carried out in shaking flask examining the effect of temperature, initial ferrous ion concentration, pulp density and particle size. variations of ph, ...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Objective(s): Iron is an essential element for living organisms. Iron overload can have detrimental effects on health. This study pertains to the protective role of berberine against ferrous sulfate-induced hepatic and renal functional disorders and histological damages in rats.Materials and Methods: The rats were divided into four groups (n=7): Sham, Ber (10 mg/kg/day for 14 days, by gavage), ...
