The measured dissolution rate of a granular medium depends on its surface area and how the changes during course measurement. Moreover, assumption that specific either remains constant or initially increases is not always valid. This paper demonstrates when particle size distribution has sufficient variance, instantaneous change in can be negative, even before smallest particles dissolve away. ...

enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...

The study aimed to determine the efficiency of a wastewater treatment plant and quality effluent discharged by into receiving water body (Okochiri River) in Eleme, Rivers State. lasted for four months. Wastewater samples were collected at various stages unit tested major parameter such as Biological Oxygen Demand (BOD), oil/grease, phenol, Dissolved (DO), Total Suspended Solids (TSS), sulphide....

Disparagement humor refers to communication that derogates or denigrates a certain target but elicits amusement. Blending two contradictory elements in terms of social approvability, the paradox disparagement has sparked three major questions: how does amusement arise from disparagement? What determines whether an attempt at is perceived be funny offensive? are unique aftereffects this...

The atomic scale homogeneity of Ce and Zr oxygen bonds represents the main reason for enhanced total oxygen storage capability of CeO2-ZrO2 (Ce/Zr = 1) as compared to that of CeO2. Here, we demonstrate that the addition of 10% Eu(3+) by wet impregnation on preformed nanosized CeO2-ZrO2 (Ce/Zr = 1) followed by calcination induces a remarkable homogeneity of 10% Eu(3+)-CeO2-ZrO2 solid solution. B...

To test proposals for the origin of oxygen absorption bands in the visible reflectance spectrum of Ganymede, the reflectance of condensed films of pure oxygen (O2) and O2-water mixtures and the evolution of O2 from the films as a function of temperature were determined. Absorption band shapes and positions for oxygen at 26 kelvin were similar to those reported for Ganymede, whereas those for th...
