abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
The drinking, borewell and sewage water in the Sanmugasikamani Nadar (S.N) street, Naivatti Nadar (N.N) street and Thiruthangal area of Sivakasi has been studied. The various constituents monitored include the physicochemical characters like pH, total solids, total dissolved solids, total suspended solids; chemical parameters like total alkalinity acidity free CO2, dissolved oxygen, total hardn...
In this research, the effect of organic fertilizers was studied on the growth performance of carps fry. This experiment was conducted in a completely randomized design with seven treatments and three replications in 300 liters of tanks within 3 months. 60 pieces of fish fry with an average weight of 0.6 ± 0.05 g were randomly storage in each tank per 0.5: 1.5: 2: 6 (respectively, 5%, 15%, 20% a...
