Erythrocytes in Abnormal Conditions, as They Appear under the Copper Peroxidase Reaction

A new application of nano-graphene oxide as a heterogeneous catalyst in crossed-aldol condensation reaction under solvent-free conditions

Nano-graphene oxide was synthesized by the oxidation of graphite powders. The structural nature of the nano-graphene oxide was characterized by a variety of techniques including XRD, TEM, FT-IR and UV/Vis. The functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. The catalytic activity of nano-graphene oxide was investigated on Crossed-...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Steam Turbines Under Abnormal Frequency Conditions in Distributed Generation Systems

Optimum reaction conditions for human lactate dehydrogenase isoenzymes as they affect total lactate dehydrogenase activity.

Optimum reaction conditions at 30#{176} ± 0.5#{176} for two continuous spectrophotometric assay procedures, lactate to pyruvate (LP) and pyruvate to lactate (PL), were determined with respect to pH at 30#{176} (pH30) substrate concentration, and coenzyme concentration for the human LDH isoenxymes. For the P L procedure, broad pH30 optima were within the range of 7.20-7.40 for all the LDH isoenz...
