The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...

Hydrogenation reaction with n-heptane on Pt/Al2O3 catalyst was investigated under the steady state condition in a fixed bed reactor. The catalyst was prepared under a variety of conditions, but the one chosen was non-acidic that is not considered a hydrocracking catalyst. The main objective was to vary the selectivity of n-heptane as a function of reaction variables es...

BACKGROUND A number of studies have demonstrated a faster rate of increase in end-expired partial pressure as a fraction of inspired (Pa/Pi) for volatile agents in the presence of high concentrations of nitrous oxide, consistent with the second gas effect. However, no study has demonstrated a similar effect on arterial blood concentrations. METHODS The authors compared arterial and end-tidal ...

Rational actor game theoretic models have had a longstanding challenge trying to explain voter turnout in the mass electorate. We analyze how partial turnout can be addressed and predicted by mechanisms in evolutionary game theory. We present two models at opposite ends of the spectrum of possible evolutionary models and show realistic partial voter turnout can be generated by either. The first...
