T is the adiabatic reaction temperature of the pyro-oxidation zone. (Barman, Ghosh, and De) also considered the formation of tar and methane reforming reaction in the pyro-Oxidation zone. The adiabatic reaction temperature is found out by considering heat balance in the zone. Enthalpy of reactants + Heat loss=Enthalpy of products = The heat loss from the oxidation zone was found to be around 10% by Chern(cite). TO is the temperature of biomass fed to the gasifier and Ta is the…

Identifying environmental reservoirs of methicillin-sensitive Staphylococcus aureus (MSSA), as well as Methicillin-resistant Staphylococcus aureus (MRSA) in the community might be critical for controlling the spread of community–acquired staphylococcal infections [27].…

3.6 Sorption isotherms The experimental adsorption equilibrium data were analyzed using Langmuir, Freundlich, Temkin and D-R isotherms. The sorption data was analyzed using linear form of all the isotherm equations Models having high correlation coefficient (R2 ) values are considered best fit to represent the sorption data. The Freundlich isotherm holds for multilayer non-ideal adsorption on heterogeneous surface and is represented by the following empirical equation: qe = KF Ce 1/n Where,…

1 enzyme Enzymes are biological catalysts. A protein compound Energy can reduce the carbon reaction. Enzymes to accelerate specific types of reactions. And the kind of substance that reacts. 2.1.1 catalysis of enzymes E is a catalyst (enzyme). S is a precursor called chop, nitrates and substance P is a product. E + S ---------------> E S ---------------> E + P. Complexometry 2.1.2 Factors affecting the enzyme. 1) What type of controlled…

INTRODUCTION Background The macrocyclic organic molecules Phthalocyanines (1) which are comparable to the naturally occurring porphyrin (2) ring systems shown in (Figure 1). The porphyrin molecule consists up of four pyrrole subunits which are associated in n-conjugation by methine carbons. 1 2 Figure 1: structures of phthalocyanine and porphyrins molcule The compound…

In the organic disordered materials, the charge transport is occurred by variable range hopping (VRH) of charge carriers between strongly localized states [22-25, 30, 58-61]. The VRH model proposed by Vissenberg and Matters model that considers the hopping percolation of thermally activated carriers between localized states is the most model used for describing charge transport in the disordered organic semiconductors and modeling the electrical characteristics OTFTs [27, 58]. Indeed, the…

Batch adsorption experiments Adsorption of the Pb2+ ions by the Fe3O4@GMA-AAm nanocomposite was measured from batch adsorption experiments by mixing 10 mg of adsorbent with an aqueous solution containing a predetermined concentration of Pb2+ ions (50 mL). The mixture was shaken at 200 rpm to reach equilibrium. After a specified time, the solid and liquid were separated by external magnet and the concentrations of Pb2+ ions were measured by AAS. To find the optimized pH in adsorption of Pb2+ ions…
