The carbon dioxide fixation by microalgae has several merits such as the COz recovery and the production of useful chemicals. Since the flue gas from a industry has some unfavorable conditions such a s high CQ concentration and toxic chemicals like SO., NO, contained in flue gas for the cultivation of m s t microalgae, it is important to apply a suitable strain of microalgae for the fixation of...

The paper divided the whole coal life cycle, explained each phase characteristics, and took coal mine in China as a study case to assess the ecological risk in coal utilization phase. The main conclusions are as follows: (1) the whole coal life cycle is divided into coal mining, processing, transportation, utilization, and waste disposal. (2) The key points of production organization and charac...

Abstract Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse storage. In order study multicomponent flue storage capacity enhanced (EOR) performance water-alternating (flue gas–WAG) injection after continuous waterflooding in an reservoir, a long core system was built. The experimental results showed that factor gas–WAG increased by 21.25% could...

High-temperature implosions are planned for the OMEGA Upgrade experimental program. By using relatively thin shell targets, temperatures much higher than 1 keV at modest compressed densities (1 to 5 g/cm3) are predicted. The goal of this work is to demonstrate that by adding a small admixture of krypton gas (-0.01 atm) to the fuel, the temperature can be conveniently diagnosed through the spect...

In this paper, we develop several techniques for computing the higher G-theory and K-theory of quotient stacks. Our main results for computing these groups are in terms of spectral sequences. We show that these spectral sequences degenerate in the case of many toric stacks, thereby providing an efficient computation of their higher K-theory. We apply our main results to give explicit descriptio...

We study the local properties of Artin stacks and their good moduli spaces, if they exist. We show that near closed points with linearly reductive stabilizer, Artin stacks formally locally admit good moduli spaces. We also give conditions for when the existence of good moduli spaces can be deduced from the existence of étale charts admitting good moduli spaces.

In this paper we propose a method to improve thewaveguides for optical communications based on 2-dimen-sional photonic crystals. To this purpose a standard channelwaveguide is sandwiched between two omnidirectionalChigrin-type 1D dielectric layer stacks. The combination oftotal internal reflection and photonic band gap reflectionenables improved confinement of optical si...

Základné vlastnosti sadrovca pre odsírenie spalín Several hundred thousand of FGD gypsum is produced annually at the Matra Power Plant (Hungary) as a byproduct of generating electricity and protecting the environment. Chemical and mechanical characteristics of this material were studied of the Department of Mining and Geotechnical Engineering, University of Miskolc (Hungary). The material in qu...
