Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

Wastewater was collected from the Dheradun industrial area situated in capital of uttrakhand. Samples were collected between the periods of November 2010 to Aug.2011 determine the following parameters, pH, temperature, turbidity, chemical oxygen demand (COD), Biological oxygen demand(BOD), dissolved oxygen (DO), conductivity, total dissolved solid (TDS), total suspended solid (TSS), sulphate, n...

INTRODUCTION We have previously reported results of precipitation studies for neonatal parenteral nutrition solutions containing calcium chloride and sodium phosphate using visual methods to determine compatibility. The purpose of this study was to do further testing of compatibility for solutions containing calcium chloride using more sensitive methods. METHODS Solutions of Trophamine (Braun...

OBJECTIVE To investigate the potential harmful effects of potassium dichromate and magnesium sulphate causing oxidative stress and reproductive toxicity in adult male mice model. METHODS The experimental work was conducted on sixty male mice (Mus musculus) divided into three groups. Mice in group B and C received potassium dichromate and magnesium sulphate of 5.0 and 500 mg/Kg body weight/ml ...

The excretion of sulphate by the isolated Malpighian tubules of Calliphora vomitoria has been investigated. Contrary to expectation, it was found that the isolated tubules are freely permeable to sulphate. The rate of sulphate secretion is comparable to the rates of secretion of both phosphate and chloride. The excretion of sulphate by the intact fly has also been verified.

The present study utilized different methods for purification of alkaline protease by using ammonium sulphate and acetone. Ammonium sulphate was found the best purifying agent and gave 109.09 fold purification of protease with 49.7% yield at 60% saturation. Dialysis was performed by using phosphate and Tris-HCl buffer and phosphate buffer was optimized to good dialyzing agent at pH 8.0.

We analyze the generation of single spatial mode, spectrally uncorrelated photon pairs via type II spontaneous parametric down-conversion in a Potassium Titanyl Phosphate (KTP) waveguide using real experimental parameters. We show that this source can be used as an efficient, heralded, pure-state single-photon source.

Essentiality of water sustain life, and a satisfactory supply must be readily available to promote health, prolong life expectancy prevent diseases. This study assesses the sources quality drinking in Piwoyi community Federal Capital Territory, Abuja, Nigeria. Thirty-five (35) Boreholes Two (2) Sachet were identified Community. Six Samples (5 1Sachet water) selected at random analyzed laborator...

We introduce the notion of ortho-symplectic super triple system, and apply it to find solutions of super Yang-Baxter equation. Also, the para-statistics are formulated as a Lie-super triple system. Let V be a N-dimensional vector space, which we write hereafter as N = Dim V. A triple product w = [x, y, z] in V is an assignment of w ǫ V for any three elements x, y, z ǫ V , which is linear in eac...
