In the present study, performance of mixed microbial anaerobic culture in treating synthetic strong wastewater containing different concentration of atrazine was evaluated (R-1). Studies were also conducted in two hybrid reactors (A-1 and A-2) with wood charcoal as adsorbing matrix along with microbes. All the reactors for the treatment of atrazine bearing wastewater were operated in sequential...

Pathways for homogeneous thermal decomposition of (C2H5)3Ga (TEGa) were followed using in situ Raman spectroscopy measurements in an up-flow, cold-wall CVD reactor. The results of Density Functional Theory (DFT) calculations were used to assign measured Raman bands to the decomposition products (Et)3Ga, (DEGa)2, (Et)GaH–Ga(Et)2 and (Et)GaH–GaH2. The results of this study are consistent with bot...

Acid mine drainage(AMD) contains high concentrations of heavy metals and has become a serious environmental problem. A pipes inserted microalgae reactor(PIMR) was constructed to cultivate microalgae and purify AMD. The effects of metal concentration, pH and sulfate after pretreatment on the removal of iron and microalgae growth were investigated. Batch studies showed that PIMR and microalgae ca...

The finite element method has proven to be versatile in the analysis of various electromagnetic phenomena. In this paper, we investigate the utility of the finite element method for guiding the design of plasma reactors. These reactors are used for processing integrated circuit substrates. The design of such reactors is based on the complex interactions between the electromagnetic fields and a ...

The state of the art and the recent progress made in dpt fusion is shortly reviewed. Experiments demonstrated 100 to 150 dt fusions per muon. The most reliable value for dt sticking is * 0.5?10. This sets a natural limit to the possible fusion output with pCF to 200 per muon. In energy applications, the concept of Yu. Petrovs pCF hybrid reactor is sketched. There are prospects for using pCF for...

The Cauchy problem for the Poisson-Nernst-Planck/Navier-Stokes model was investigated by the first author in [Transport Theory Statist. Phys. 31 (2002), 333–366], where a local existence-uniqueness theory was demonstrated, based upon Kato’s framework for examining evolution equations. In this article, the existence of a global weak solution is proved to hold for the model, in the case of the in...

Lebedev Physical Institute Russian Academy Sciences (Moscow). relevance research is related use excimer UV lasers as a driver for thermonuclear r...

Global hybrid simulations of energetic particle effects on the n=1 internal kink mode have been carried out for tokamaks. For the Internationa Thermonuclear Experimental Reactor (ITER) [ITER Physics Basis Editors et al, Nucl. Fusion 3 ̄ 9, 2137 (1999).], it is shown that alpha particle effects are stabilizing for the internal kink mode. However, the elongation of ITER reduces the stabilization e...

The present work aims to evaluate filamentous bulking control in hybrid systems. For this study, four sequencing batch reactors (SBR) fed with acetate were operated without (SBR1) and with support for biofilm growth [5 % (SBR2), 10 % (SBR3) and 20 % (SBR4) of the reactor volume]. The results demonstrated an overabundance of a filamentous fungi-like microorganism in the SBR operating just with s...
