CSR can reduce costs of environmental pollution and decrease a tax, so CSR can make organization to better quality.
However, if CSR can be used for enhancing CEO’s reputation, the expenditure of CSR will become

Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biolog

of food irradiated with doses above 10 kGy. This Study Group concluded that there is no scientific basis for limiting absorbed doses to the upper level of 10 kGy as currently recommended by the Codex Alimentarius Commission. Food irradiation technology is safe to such a degree that as long as the sensory qualities of food are retained and harmful microorganisms are destroyed, the actual amount of

Complete-mix activated-sludge(CMAS)
The CMAS process is an application of the flow regime of a continuous-flow stirred-tank reactor. Settled wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen deman
Ⅰ. Introduction
1. Study background and objectives
Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% ofwater consumption, and 25% of wood consumption, so buildings are mainly responsible for
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
