Ebook "Bacteria-metal interactions" provides a detailed description and analysis of the reduction and metabolism of metals and metalloids by sulfate reducing bacteria. The molecular mechanisms of bacterial resistance to copper are examined as well as extracellular electron transfer and bacterial metal oxide respiration. Furthermore, in this book enrichment, isolation, and physiology of magnetotactic bacteria are discussed.

This paper reviews the durability of concrete containing pozzolans in marine environments, which mainly focuses on resistance to chloride ion penetration and sulfate attack. The results of previous literature showed that the main ions of seawater are almost similar but the salinity varies with location. The mechanism of chemical reaction between seawater and concrete was carefully reviewed and explained.

Fly ash is an active mineral admixture used commonly in the production of blended Portland cement. Fly ash improves many important properties of cement and cement concrete: increasing late compressive strength, increasing sulfate resistance, reducing heat of hydration, reducing alkali-silica reaction and reducing water permeability.

The infusion of magnesium sulfate is well known to reduce arterial pressure and attenuate hemodynamic response to pneumoperitoneum. This study aimed to investigate whether different doses of magnesium sulfate can effectively attenuate the pneumoperitoneum-related hemodynamic changes and the release of vasopressin in patients undergoing laparoscopic gastrointestinal surgery.

Trastuzumab is an antibody widely used in the treatment of breast cancer cases that test positive for the human epidermal growth factor receptor 2 (HER2). Many patients, however, become resistant to this antibody, whose resistance has become a major focus in breast cancer research.

A novel extracellular endoglucanase from a basidiomycete strain Peniophora sp. NDVN01 was purified 2.8-fold to homogeneity through ammonium sulfate precipitation and gel filtration with Bio-Gel P-100 and Sephadex G-75. The endoglucanase had a specific activity of 163.8 U/mg protein and a molecular mass of 32 kDa.

The properties of different forms of carbon and their potential, as active mass additives, for influencing the performance of valve-regulated lead–acid batteries are reviewed. Carbon additives to the positive active-mass appear to benefit capacity, but are progressively lost due to oxidation. Some forms of carbon in the negative active-material are able to resist the tendency to sulfation during high-rate partial-state-of-charge operation to some considerable extent, but the mechanism.
