ions, Modules, Extensions and Layers The power of an abstraction is usually derived from creating a simplified domain where a set of details is hidden. A module is an abstraction in this sense if one can use the module without having to know its internal details. Yet the notion of a module does not fully encompass what is meant by an abstraction in abstract algebra. That is because many abstrac...

This study reports the competitive adsorption of Ni(II), Cd(II) and Cr(VI) onto sunflower waste biomass carbons, viz. sunflower head carbon and sunflower stem carbon from multi-metal aqueous solution. The adsorption capacity of the adsorbents was highest in mono-metal system but decreased with increase in the number of coions. The adsorption capacity in mono-metal system was 0.32 and 0.45 mM/g ...

In the present study, a novel indigenous bacterium was isolated from the effluent of Electroplating industry having capability of biotransforming Cr(VI) ions into Cr(III) ions. Morphological, Physiological and biochemical characterization of the bacterial strain was carried out and later sequence analysis of 16S rRNA gene of the strain identified it as Microbacterium maritypicum. By utilizing t...

Recombination in plasmas containing H(3)(+) ions occurs not only by binary recombination but also by third-body-assisted mechanisms, the principal subject of this contribution. Third-body effects on recombination are of interest for model calculations of hydrogen discharges, their spectral emissions and the inference of binary recombination coefficients from plasma afterglow data.

Nitrate and halide ions coexist in particles generated in marine regions, around alkaline dry lakes, and in the Arctic snowpack. Although the photochemistry of nitrate ions in bulk aqueous solution is well known, there is recent evidence that it may be more efficient at liquid-gas interfaces, and that the presence of other ions in solution may enhance interfacial reactivity. This study examines...

Predictions of the transport properties self-diffusion coefficient and shear viscosity are presented for a recently developed molecular ammonia model. These data show mean unsigned deviations to the experiment over a temperature range from 200 to 500 K of 8 % for the self-diffusion coefficient and 12% for the shear viscosity. Furthermore, the vapor-liquid equilibria of the ternary system carbon...

In this paper, we investigate binary response models for heterogeneous panel data with interactive fixed effects by allowing both the cross sectional dimension and temporal to diverge. From a practical point of view, proposed framework can be applied predict probability corporate failure, conduct credit rating analysis, etc. Theoretically methodologically, establish link between maximum likelih...
