The geometrical parameters, normal vibration frequencies, and thermochemical characteristics of the Na2Cl+, NaCl 2−, Na3Cl 2+, and Na2Cl 3− ions in saturated vapors over sodium chloride were calculated by the ab initio ...

This paper described the role of substrate (soil) with respect to the type of macrophytes (plants) planted in the wastewater treatment in Horizontal Subsurface Flow (HSSF) Constructed wetlands (CWs). Wastewater parameters ...

The adoption and continued use of improved stoves in the developing countries is of social, economic and environmental concern. In most developing countries, biomass-based energy accounts for more than 90% of all household ...

The geometric parameters, normal vibration frequencies, and thermochemical characteristics of the ions present in vapor over sodium fluoride, Na2F+, Na3F 2+, NaF 2−, and Na2F 3−, were calculated ab initio by the Hartree-Fock ...

Selective laser sintering (SLS) is a rapid prototyping technique which is used to manufacture plastic and metal models. The porosity of the final product obtained by SLS can be controlled by changing the energy density ...
