Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

In order to fully understand what a given boiler needs for treatment, a basic study of its supply water must be done first. Three types of impurities exist in all supplies and can cause a wide range of problems in boilers and kilns. These impurities are suspended solids, dissolved solids, and dissolved gasses. Water picks up the impurities from the ground it contacts and the air through which i...

In the classical approach to dealing with near-field radiative heat exchange between two closely spaced bodies, no coupling different carriers inside materials and thermal photons is usually considered. Here, we provide an overview of current state research on this solids sizes while paying specific attention impact conduction regime conduction–radiation coupling. We describe how shape affects ...

Au/CeO₂ solids were prepared by two methods: deposition-precipitation (DP) and impregnation (Imp). The prepared solids were calcined under air at 400°C. Both types of catalysts have been tested in the total oxidation of propylene, toluene, carbon monoxide, and carbon black. Au/CeO₂-DP solids were the most reactive owing to the high number of gold nanoparticles and Au⁺ species and the low concen...

If nuclear reactions happen in solids, heat generated from the reaction center is diffused. In this study, the thermal conduction from the centers of a DD reaction in solids induced by the Bose-Einstein condensation is considered. The voids in solids are assumed as the sites of the reaction centers. The equations of the thermal conduction are solved using Fourier expansion. The calculated resul...

BACKGROUND The BioEnergy Science Center (BESC) developed a high-throughput screening method to rapidly identify low-recalcitrance biomass variants. Because the customary separation and analysis of liquid and solids between pretreatment and enzymatic hydrolysis used in conventional analyses is slow, labor-intensive and very difficult to automate, a streamlined approach we term 'co-hydrolysis' wa...

Refractometric analysis of total solids in serum and urine is simple, accurate, and rapid. Adolph (1) demonstrated the high coefficient of correlation between refractive index and total solids of dog plasma and subsequently employed refractometry as an index of the total solids of human serum (2). Blohm (3), using a dipping refractometer, showed for human urine that the reading given by that fl...

Sewage solids are usually characterized by non-specific parameters such as suspended solids. The suspended solids has been shown to be an inadequate index for advanced water treatment processes. In this study, the sewages solids particle size distribution was used to provide more detailed information on sewage characteristic. It is hoped that, by introducing particle size distribution, the mech...
