This account serves as the introduction to a Special Issue of journal Environmental Biology Fishes. It includes 18 contributions, 12 which deal predominantly with warming, four explicitly deoxygenation, one providing framework, and addressing how warming deoxygenation—which all contributions view, implicitly or explicitly, leading “oxythermic” stress—are used pretext cover up overfishing. The “...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

We studied the role of the sodium-potassium pump in erythrocytes of 12 patients with sickle cell anemia (SS). Ouabain-binding sites per cell and pump-mediated Rb/K uptake were significantly higher in SS patients than in white or black controls. Ouabainresistant Rb/K influx was also greater than in normal controls or patients with sickle cell trait. Deoxygenation of SS erythrocytes increased oua...

A newly designed capillary deoxygenator has been constructed by using microporous polypropylene hollow fibers sealed into an airtight plexiglass housing. Oxygenated red cell suspensions and hemoglobin solutions flowing through the hollow fibers were subjected to deoxygenation with a gas mixture composed of 95 percent N2 and 5 percent CO2 passed through the housing. At a given flow rate of the o...

Deoxygenation-induced cation movements in sickle cells were inhibited 80% to 85% by the anion transport inhibitor, 4,4’-diisothiocyano-2,2’disulfostilbene (DIDS). Morphologic sickling was not altered by DlDS treatment, demonstrating that morphologic sickling was not sufficient to produce cation leaks in sickle cells. DlDS inhibition of deoxygenationinduced cation flux was not affected when Irep...

Abstract Absorption by aqueous solutions of alkanolamines is the most mature technology for removing carbon dioxide (?? 2 ) from natural gas, off-gases power engineering, and other mixtures. The possible presence oxygen in gas mixture being treated or air leakage into absorption treatment system leads to oxidative degradation amine deactivation liquid with formation a wide range corrosion-activ...

Achievement of appropriate precision is a major challenge for the clinical laboratory, particularly in specialized fields such as enzymology and immunochemistry. Especially in immunochemistry, where accuracy can only poorly be checked because of a lack of reference methods and a multitude of detectable epitopes, precision remains an important index of quality. In immunochemical methods there ar...
