A pilot-scale multilayer rapid infiltration system (MRIS) for domestic wastewater treatment was established and efficient removal of ammonia and chemical oxygen demand (COD) was achieved in this study. The microbial community composition and abundance of ammonia oxidizers were investigated. Efficient biofilms of ammonia oxidizers in the stationary phase (packing material) was formed successfull...

Water is very crucial for surviving life of all human being and animals. Without water nobody can be survived. The existing manuscript associated with Anchar Lake water. vulgarized by unwanted materials. quality tests reevaluate attributes. Scrupulous substances are: Dissolved Oxygen (DO), Total Alkalinity(TA), Electric Conductivity(EC), Potential Hydrogen(pH), Phosphate(P), Dissolve Solids(TDS...

In this study, we report the detection of dissolve oxygen (DO) by using a blend Ruthenium oxide and polyaniline (PANI) coated on platinum electrodes. Optical properties PANI were characterized Ultraviolet - Visible (UV-Vis) Fourier-transform infrared (FTIR) spectroscopy. order to study sensitivity thin films PANI: blend, cyclic voltammetry (CV) measurements was performed with electrodes oxide. ...

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...

This paper presents a novel, real-time, minimal-latency technique for dissolve detection which handles the widely varying camera techniques, expertise, and overall video quality seen in amateur, semi-professional, and professional video footage. We achieve 88% recall and 93% precision for dissolve detection. In contrast, on the same data set, at a similar recall rate (87%), DCD has more than 3 ...

We survey in a uni...ed framework the recent literature on partnership dissolution in settings where agents have interdependent values. Contrary to the private values case where the main obstacle that hinders the construction of e¢cient trading mechanisms is the asymmetry in initial endowments, we ...nd that informational asymmetries play here a major role. For settings where the ...rst-best ca...

This preliminary study developed a novel cellulose pretreatment method for cost-effective cellulosic utilization using a modified cuprammonium solution as a solvent to dissolve cellulose followed by molecular oxygen/Fenton depolymerization. The modified cuprammonium solution is composed of cuprammonium solution and a special catalyst that could efficiently enhance cellulosic oxygen sensitivity ...

Automatic shot boundary detection has been an active research area for nearly a decade and has led to high performance detection algorithms for hard cuts, fades and wipes. Reliable dissolve detection, however, is still an unsolved problem. In this paper, we present the first robust and reliable dissolve detection system. A detection rate of 69% was achieved while reducing the false alarm rate t...
