This study is to evaluate the biological disinfectant ability of Aloe vera (under different conditions and parameters) on coliform isolates from leachate that emanate a dumpsite.Leachate samplewas subjected presumptive test presence coliforms in them; positive samples were further confirmatory identify thermo-tolerant nature coliform. The Escherichia coli (FTE) Thermo-tolerant (non E. coli) (FT...

Purpose – The purpose of this paper was to study the combined effect of hygro and thermo-mechanical behavior on a plastic encapsulated micro-electro-mechanical systems (MEMS) package during the reflow process after exposed to a humid environment for a prolonged time. Plastic encapsulated electronic packages absorb moisture when they are subjected to humid ambient conditions. Design/methodology/...

Abstract In the present research, a numerical modeling approach of initial stage consolidation during spark plasma sintering on microscopic scale is presented. The solution fully coupled thermo-electro-mechanical problem also accounting for grain boundary and surface diffusion found by using staggered way. finite-element method applied solving while finite-difference problem. A Lagrange-based n...

Taking the standard size coal block samples defined by ISRM as research objects, both properties of methane diffusion of coal block under triaxial compressive stress and characteristic influences caused by methane pressure were systematically studied with thermo-fluid-solid coupling with triaxial servocontrolled seepage equipment of methane-containing coal. The result shows the methane diffusio...

Abstract: Neutron irradiation plays an important role in nuclear-induced degradation for concrete shielding materials, specifically determining the radiation induced volume expansion (RIVE) phenomenon driving its failure. When analyzing at structural level effects of nuclear on concrete, a non-uniformed distribution neutron must be considered. This can done via particle transport calculations p...

Comparatively little attention has been given to multicomponent diffusion effects in lean hydrogen-air flames, in spite of the importance of these flames in safety and their potential importance to future energy technologies. Prior direct numerical simulations either have considered only the mixture-averaged transport model, or have been limited to stabilized flames that do not exhibit the ther...

The purpose of this work is to investigate, within the context extended thermo-diffusion theory, transient responses for a half-space with variable thermal conductivity and diffusivity. half-bounding space’s surface traction-free exposed time-dependent shock, but chemical potential believed be known function time. Because nonlinear equations are complicated, finite element technique applied sol...
