This work studied the physiochemical properties of Ajali River polluted with Industrial effluent at different sampling points from -250m upstream before pollution to 2250m downstream. Statistical package for Social Science (SPSS) was used statistical analysis. Post ANOVA test determine if there is any significant difference between means and which distance occurred. A measuring wheel Global Pos...

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...

introduction: oxygen is a drug and physician and nurses should be familiar with the effects and potential risks of oxygen therapy. the current study aimed to assess familiarity of physicians and nurses with various aspects of oxygen therapy. method: in this cross sectional study, the familiarity of physicians and nurses with various aspects of oxygen therapy in a teaching hospital was evaluated...

The quest for an effective alternative means for effluent treatment is a major concern of the modern-day scientist. Fungi have been attracting a growing interest for the biological treatment of industrial wastewater. In this study, Saccharomycescerevisiae and Torulasporadelbrueckii were isolated from spoiled watermelon and inoculated into different concentrations of effluent. The inoculants wer...

Aerated-anoxic processes operate under the principle that small additions of oxygen to an anoxic reactor induce simultaneous nitrification and denitrification. In these systems, ammonia oxidation in the anoxic zone can easily account for 30-50% of the total nitrification in the reactor, even though the dissolve oxygen concentration is usually below detection limit. To investigate whether the ni...

The study was conducted in 2013/14 with the objective of determining the effects of Bahir Dar textile factory effluents on the head of Blue Nile River water quality. Dissolve oxygen was higher at the upstream site of the river, whereas BOD5, TDS, and total alkalinity values were higher at wastewater outlet of the factory site. The mean values of dissolved oxygen, BOD5, and total alkalinity were...

The study of the isotopic composition of structural carbonate in fossil vertebrate hydroxylapatite has been hampered by uncertainty concerning sample treatment and arguments about the susceptibility of this material to diagenetic alteration. Our investigation of sample treatment reveals that some methods commonly used to remove organic matter and secondary minerals induce significant isotopic o...

1. Protein fractions derived from tubercle bacilli are toxic to the interior of Amoeba dubia but have no action on the plasmalemma. 2. Phosphatide fractions dissolve the plasmalemma but have no effect on the internal cytoplasm. 3. The fatty acid fraction has a marked solvent action on the plasmalemma when brought in contact with the surface of the cell. When injected it may slowly penetrate the...

The Udu River is a major source of commerce and provides water for agricultural domestic use to the people, hence we studied physicochemical parameters (pH, electrical conductivity, TSS, TDS, turbidity, Salinity, DO, COD, BOD, chlorides, sodium, potassium, total hardness, alkalinity, nitrates, ammonium, sulphates) as well evaluation degree metal contamination (iron, zinc, cadmium, nickel, coppe...
