In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

This Special Issue “Bio-Geochemistry of Heavy Metals/Metalloids” contains a series papers that cover range topics highlighting the role microorganisms in ore-forming biochemical processes and potential environmental risk (the first to fourth papers), assessment potentially toxic element contamination using plants living benthic Foraminifera fifth sixth phytoremediation contaminated land seventh...

agricultural landscapes with the green veins and forests patches are forming many parts of european landscapes. in spite of many ecological, economic and agricultural advantages of these elements, they have been changed due to agricultural intensification. we studied changes of these elements, their relations with agricultural activities, farming systems and land use of the adjacent parcel in t...

superplastic forming (spf) is a manufacturing process utilized in the automotive industry to produce complex geometry aluminum or magnesium alloy components which cannot be fabricated at room temperature. this paper investigates the effects of the die entry radius and the interfacial friction coefficient on the required forming time and thickness distribution of a superplastic formed part. a co...

Russia is one of the main producers agricultural products, which determined by large size its territory, natural conditions, land suitable for production products and other factors. Agriculture a significant industry, development focused on both making profit ensuring food national security. The leaders in are: Krasnodar Krai, Rostov region, Belgorod Voronezh region. Kurgan region an industrial...
