Chromium (Cr) is one of the most toxic chemical compounds due to the common use of chromium compounds in industry in addition to its natural sources (Costa et al., 2003). Exposure to chromium occurs via contaminants found in drinking water and food, through air containing particulates or mists of hexavalent chromium Cr (VI) compounds, or through skin contact with soil at hazardous waste sites (National Institute for Occupational Safety and Health, 2013). Cr (VI) may be found in drinking water…

per square foot of net land size This information is analyzed in the following chart to determine the most stable and consistent unit of comparison to be applied in valuing the subject property based upon the sale price per unit of comparison coefficient of dispersion (COD). Per the IAAO COD is “the most generally useful measure of variability or uniformity.” The COD measures the average percentage deviation of the ratios from the median ratio and is calculated by the following steps: 1.…

confirmed the above-mentioned results (Sui et al. 1999). Following surveys have evaluated parameters of the catalyst layer. For instant, Wang et al. studied the effect of structural parameters in the catalyst layer and determined oxygen diffusion coefficient, proton conductivity, and agglomerate size as key parameters (Wang et al. 2004). Furthermore, Sun et al. accounted for catalyst layer thickness, catalyst loading, and ionomer content as the most important parameters (Sun, Peppley and Karan…

Chemicals Congo red (CR) an anionic dye (C32H22N6Na2O6S2 and Molar Mass as 696.7 gmol-1) used in the present work (Fig.1a) and zinc acetate dihydrate were purchased from LOBA Chemie Company, India. Methylene blue (MB) a cationic dye (C16H18N3SCl and Molar Mass of 319.85 gmol-1) as shown in Fig.1b, was purchased from Oxford laboratory reagent Co. Zinc acetate used for the preparation of nanoparticles ZnO and sodium hydroxide were purchased from Biotech laboratory chemicals company. Ethyl alcohol…

infection, hypoplasia, sinus atelectasis, pneumosinus dilatans. Treatment methods, such as functional endoscopic sinus surgery, require that the volumes and detailed anatomy of the paranasal sinuses be well-known [1,3-6]. If a digital volumetric determination of the lesions using a CT computer is not possible, the ellipsoid and the Cavalieri method offer an alternative. The Cavalieri Estimator is more accurate than the Ellipsoid Method but takes longer [7,8]. In this study, we combined the…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

Pure Copper Iodide were synthesised and the mass percentage of Copper in purified Copper (I) Iodide sample were determined by applying Beer’s Law in UV-Vis spectroscopy. Absorbance value of Cu-cuprizone solution was measured. Using the absorbance value of 0.3576 , the concentration of the Cu-cuprizone solution were obtained at 0.001389g/L with reference to the graph of the standard solution A to D. The graph of absorbance against concentration of the standard solution A to D shows a linear…

To measure the customers’ perception of the service quality provided by Impelpro, SERVPERF model is used in this study. SERVPERF specifically measures the client's impression of service execution and accept that respondents naturally look at their view of the service quality levels with their desires of those services. The model contains 22 questions and a five point likert scale is used to measure the performance. For all the service quality dimensions (Tangibles, Reliability, Responsiveness,…

INTRODUCTION Chemically and thermodynamically foam is an unstable, dispersed system of entrapment of gaseous molecules in solid or liquid matter. Instability of foam is caused generally due to coalescence, liquid drainage and disproportion of bubbles. Foam being aqueous system can be produced using surfactants available commercially. The types of surfactants used in preparation of aqueous foam influence the foam properties (Eisner et al., 2007; Bhakta and Ruckenstein, 1995). Successful foam…
