Radiation resistant bacteria have adopted a variety of ingenious strategies for survival under the high dose of radiation, for example through their pigments. In the present study, two ultraviolet-C (UVC) radiation tolerant bacteria, named NM1 and NM3 strains, were isolated from the industrial waste and soil that identified by the molecular analysis. Survival assay of irradiated bacteria was pe...

Tar formation is the main bottleneck for biomass gasification technology. A novel rotary kiln type biomass gasification process was proposed. The concept design was based on air staging and process separation. This concept was demonstrated on a pilot scale rotary kiln reactor under ambient pressure and autothermic conditions. The pilot scale gasifier was divided into three different reaction re...

Results obtained by the indirect zonal isotropic uniform random (IUR) estimation were compared with those obtained by the direct point and interception counting methods on vertical (VS) or IUR sections in a stereological study of bovine articular cartilage collagen fibrils at the ultrastructural level. Besides comparisons between the direct and indirect estimations (direct IUR vs indirect IUR e...

One of the most challenging issues concerning the gasification of oil palm fronds (OPF) is the presence of tar and particulates formed during the process considering its high volatile matter content. In this study, a tar sampling train custom built based on standard tar sampling protocols was used to quantify the gravimetric concentration of tar (g/Nm3) in syngas produced from downdraft gasific...

The stoicheiometrically 1:1 adduct of 1,4,7,10,13,16-hexaoxa-cyclooctadecane with m-nitroaniline, C18H30N2O8, Mr = 402.45, crystallises from toluene in red-orange prisms, (probable) space group P i , a = 801.8(3), b = 920.4(3), c = 1403.3(4) pm, a = 80.40(4), ß = 79.79(4), y = 85.95(3)°, V = 1.07910 nm3, Z = 2, dcaic. = 1.238 Mgm~3. Structure refinement converged at R = 0.060 (Rw = 0.002) for 2...

Biogas is a promising renewable energy source; however, it needs to be upgraded increase its low calorific value. In this study, oxidative coupling of methane (OCM) was selected convert higher fuel standard. Prior establishing the scaled-up OCM process, effect organic/inorganic binders on catalytic activity examined. The selection and composition catalyst pellet influenced pore structure, fract...

El principal objetivo de esta investigación es caracterizar la gasificación hojas y tallos obtenidos como biomasa residual en el cultivo palma aceite utilizando aire agente gasificante. Se desarrolla una experimentación tipo barrido se utiliza un reactor caída libre flujo descendente. A 800°C relación equivalencia (ER) 0.24, los resultados muestran para las rendimiento 1.85 Nm3 gas/kg sec...

Rapid acidification and inhibition by d-limonene are major challenges of biogas production from citrus waste. As limonene is a hydrophobic chemical, this challenge was encountered using hydrophilic polyvinylidine difluoride (PVDF) membranes in a biogas reactor. The more sensitive methane-producing archaea were encapsulated in the membranes, while freely suspended digesting bacteria were present...

CO2 has characteristic properties and reactions at the converter smelting temperature, chemical reaction between elements such as C Si in molten pool bubble proliferation cooling effects, which can effectively improve kinetic thermodynamic conditions of smelting. Here, an experimental study industrial test on application were carried out. The effects Mode-1 Mode-2 with total injection amounts 2...
