Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Biomaterials are used to replace a part of the body functions lost due to illness or to improve functions and to correct anomalies. The import...

Metakaoline is a relatively new pozzolanic additive, obtained by calcination of kaolin clay at relatively low temperatures. Themselves pozzolanic additives are known for a very long time.

The investigation of the fault tectonics in the Kovdor carbonatite intrusion (NW Russia) has resulted in the identification of a new brittle deformations type. It is formed due to the simultaneous turn of fissure planes at discrete angles around two orthogonal guiding lines (axes), where one is represented by a vertical massif symmetry axis (L1), and the other axis (L2) lies horizontally in the fracture plane. Nonetheless, the rotation along the both axes is codirectional, i.e., when moving counterclockwise around...

Water is essential for life. The amount of drinking water required is variable. It depends on physical activity, age, health issues, and environmental conditions. For those working in a hot climate, up to 16 liters a day may be required. Water makes up about 60% of weight in men and 55% of weight in women. Infants are about 70% to 80% water while the elderly are around 45%. [1] Far from thinking of promoting certain national bodies, the study shows several necessary aspects for evaluating drinking water situation ...

The bioeconomy field covers the agricultural domain, all manufacturing sectors and associated services that involve any form of biological resources. Thereby, the research on bioeconomy is dependent on the data collection both about biological resources (such as plants, animals, and microorganisms) and about the connex phenomena.
