Enzyme is a protein molecule acting as catalyst in enzyme reaction. Enzyme inhibition is a science of enzyme-substrate reaction influenced by the presence of any organic chemical or inorganic metal or biosynthetic compound due to their covalent or non-covalent interactions with enzyme active site. It is well known that all these inhibitors follow same rule to interplay in enzyme reaction. Prese...

Metal cutting processes are important due to increased consumer demands for quality metal cutting related products (more precise tolerances and better product surface roughness) that has driven the metal cutting industry to continuously improve quality control of metal cutting processes. This paper presents optimum surface roughness by using milling mould aluminium alloys (AA6061-T6) with Respo...

We relax some assumptions of the traditional scheduling problem and suggest an adapted meta-heuristic algorithm to optimize efficient utilization of resources and quick response to demands simultaneously. We intend to bridge the existing gap between theory and real industrial scheduling assumptions (e.g., hot metal rolling industry, chemical and pharmaceutical industries). We adapt and evaluate...

We analyzed blood lead (PbB) level from the 2003 health surveillance results of 13,043 lead workers from 1,217 total lead industries to evaluate lead intoxication at low level in Korea. Geometric mean of PbB was 6.08 microg/dl and 56.6% and 7.9% of total lead workers had PbB level over than 5 microg/dl and 25 microg/dl, respectively. Male showed relatively higher PbB level compared to women, bu...

bullwhip effect phenomenon is what reduces the efficiency of the supply chain. the effect occurs when demand changes in the supply chain face with a lot of volatility. so far, several key factors have been identified as causes of this phenomenon. since the steel industry, is the basic one, its efficiency is of great importance. therefore, in this study influencing factors on bullwhip effect in ...

an increase in heavy metal pollution in the soils of arak due to industrialization and urbanization has become an environmental problem. the region hosts several industrial facilities which are the main source for hazardous wastes which include electric, metal, automotive supply industry, food, machinery, and chemicals. soil samples were collected from these industrial areas in the central and ...

Enzymes Immobilization onto different types of the substrate could be helpful in various applicationsof biomedical devices and biosensors. Enzyme activity and stability could be affected by support andmethod of immobilization. In this study, the silver metal foam was successfully synthesized by thesoft-shell method and then was coated with silica. Then, glucose oxidase (GOx) immobilized on nonc...
