the caspian sea contains great resources of oil and gas. the caspian sea is a 700- mile- long body of water in central asia, land located between azerbaijan, iran, kazakhstan, russia and turkmenistan. iran was challenges and opportunities in the caspian region. key question in this thesis includes three section that first question, opportunities of iran in the caspian region, second question ch...
Hydrogen and electricity produced from coal will represent a significant share in the energy mix within the foreseeable future. Various novel processes are developed or currently under development for hydrogen and electricity production from coal derived syngas. The commercial coal to hydrogen and coal to electricity processes include the coal gasification-water gas shift process and integrated...
A series of different M/TiO2 catalysts are prepared, where M = Au, Pt, Pd and Ag, with a 0.2 wt% loading, tested for activity as photocatalysts the water gas shift reaction, WGSR, using continuous flow, phase reactor. For both thermal (dark) photocatalytic (UV irradiated) WGSR best catalyst/photocatalyst is Au/TiO2. The kinetics studied function reactor temperature, Au loading concentrations CO...

The catalytic reduction of SO2 to elemental sulfur by CO or CH4 over ceria-based catalysts under demanding operating conditions is reported in this paper. Cuor Ni-containing ceria catalysts have been shown before to be highly active and selective for SO2 reduction by CO in dry gas streams or in the presence of low amounts of H2O. In this work, the activity/selectivity of 10 at.%La-doped ceria, ...
Group A streptococci (GAS) are genetically diverse. Determination of strain features can reveal associations with disease and resistance and assist in vaccine formulation. We employed whole-genome sequence (WGS)-based characterization of 1,454 invasive GAS isolates recovered in 2015 by Active Bacterial Core Surveillance and performed conventional antimicrobial susceptibility testing. Prediction...
A combined and sequential use of Monte Carlo simulations and quantum mechanical calculations is made to analyze the spectral shift of the lowest pi-pi* transition of phenol in water. The solute polarization is included using electrostatic embedded calculations at the MP2/aug-cc-pVDZ level giving a dipole moment of 2.25 D, corresponding to an increase of 76% compared to the calculated gas-phase ...
Epidemiological studies consistently find that diets rich in whole-grain (WG) cereals lead to decreased risk of disease compared with refined grain (RG)-based diets. Aside from a greater amount of fiber and micronutrients, possible mechanisms for why WGs may be beneficial for health remain speculative. In an exploratory, randomized, researcher-blinded, crossover trial, we measured metabolic pro...
