Eutrophication is one of the most important problems in the ecology of fresh waters. The aim of the present work was to investigate the effect of eutrophic overload (nitrates and phosphates) to the structure of zoobenthos in two types of experimental waters. Experimental mesocosms containing ground and water were used to investigate nitrate-phosphorus effect to hydrobionts. The negative effects...

The treatment of electroplating industrial effluent by coconut husk was carried out by analyzing the physico-chemical parameters of the effluent such as pH, salinity, calcium, magnesium, phosphates, nitrates, BOD3 30C̊ and total solids using standard methods. The efficiency of coconut husk was tested by using it in different quantities such as 25, 50, 75 and 100 grams for five days. As a result,...

chest pain group. 3) Effective treatment: The efficacy of three standard antianginal drugs on silent myocardial ischemia was studied in 43 patients with EA using Holter monitoring. Antianginal drugs used were long-acting isosorbide dinitrate 40-80 mg/day for nitrates (17 patients), diltiazem 90-180 mg/day for calcium antagonists (13 patients), propranolol 30-60 mg/day or metoprolol 60-120 mg/da...
