A pyrolysis of compost for the production of syngas with an explicit H2/CO = 2 or H2/CO = 3 was investigated in this study. The composts were obtained from nonhybrid (perennial) grasses (NHG) and hybrid (perennial) grasses (HG). Discrepancies in H2 evolution profiles were found between NHG and HG composts. In addition, positive correlations for NHG composts were obtained between (i) H2 yield an...

EU enlargement is supposed to entail profound impact on the location of economic activities in Europe. Although there is concern about the implications of enlargement for regional disparities in the EU, corresponding empirical results are still rare. The objective of this analysis is to provide empirical evidence on enlargement effects with a special focus on border regions in the EU27 since th...

Worker Cooperatives and Democratic Governance A worker co-operative is a firm that is owned and managed by those who work in it. This paper provides a selective review of research in economics on worker cooperatives. It concentrates on the volatility of earnings and employment in the co-ops compared with conventional capitalist firms; on the long-term viability of co-ops; on the relative produc...

The deuterium isotope effect in the steady state CO oxidation rate over Au/ -Al2O3 in the presence of H2 or H2O and the effect of pretreatment on an uncalcined catalyst were studied. In a reaction feed containing 1% CO, 0.5% O2, and 40.5% H2 at room temperature, CO oxidation exhibited a deuterium isotope effect (kH/kD) of 1.4 ± 0.2. The rate of D2 oxidation was also slower than the oxidation of...

BACKGROUND Citrobacter amalonaticus Y19 is a good biocatalyst for production of hydrogen (H2) from oxidation of carbon monoxide (CO) via the so-called water-gas-shift reaction (WGSR). It has a high H2-production activity (23.83 mmol H2 g-1 cell h-1) from CO, and can grow well to a high density on various sugars. However, its H2-production activity is expressed only when CO is present as an indu...

in this paper, modeling and optimization of fischer-tropsch synthesis is considered in a fixed-bed catalytic reactor using an industrial fe-cu-k catalyst. a one dimensional pseudo-homogenous plug flow model without axial dispersion is developed for converting syngas to heavy hydrocarbons. the effects of temperature, pressure, h2 to co ratio in feed stream, and co molar flow on the mass flow rat...

The issue of financial integration, at the country level, is a well-documented phenomenon in the area of International Portfolio Diversification (IPD). Despite the increasing degree of financial integration, it is important to investigate the global integration at industry level to capture the potential benefits of IPD. Thus, this study attempts to evaluate the potential advantages of IPD for i...

This paper develops an asymmetric information model that provides an economic rational for co-signing. It is shown that banks can solve adverse selection problems by offering a co-signing contract that induces a risky and a safe firm to group together. The equilibrium co-signing debt contract strictly Pareto dominates an equilibrium without a co-signer if the latter entails rationing. The debt ...

BACKGROUND Fermentative hydrogen (H2) production suffers from low carbon-to-H2 yield, to which problem, co-production of ethanol and H2 has been proposed as a solution. For improved co-production of H2 and ethanol, we developed Escherichia coli BW25113 ΔhycA ΔhyaAB ΔhybBC ΔldhA ΔfrdAB Δpta-ackA ΔpfkA (SH8*) and overexpressed Zwf and Gnd, the key enzymes in the pentose-phosphate (PP) pathway (SH...
