games. The reason is because there is only one military based game that is dominating the market every year is Call of Duty. As a COD (Call of Duty) player myself‚ I have been since Black Ops. So I can understand the appeal of these games‚ single player campaign in COD offers some of the exhilarating action. I never knew that there would be a FPS that could rival COD until I played Battlefield 3.

reactor was started-up in step-wise loading rates beginning from 0.05kg carbon oxygen demand (COD)/m3-day to 3.50kg-COD/m3-day. The hydraulic retention time (HRT) was slowly decreased from 96 hrs to eight hrs. It was observed that the removal efficiency of COD of more than 73% can be easily achieved at an HRT of more than 16 hours corresponding to an average organic loading rate (OLR) of 3.0kg-COD/m3-day‚ at neutral pH and constant temperature of 29oC. The average VFAs (volatile fatty acids)

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

The manufacture of paper yields a significant quantity of waste-water. It is estimated that 273–450 m3 of water is required to produce 1 ton of paper and about 60– 300 m3 of wastewater is discharged (Subramanium 1976; Thompson et al.

Do you think it is possible to overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to
