K promotion of Co catalysts for the two-step methane homologation reaction

The promotion of Co catalysts with K has been examined for the two-step CH₄ homologation reaction. The effect of K was strongly influenced by the catalyst support. In the case of the SiO₂ supported catalyst, addition of K increased the CH₄ decomposition activity and decreased the second-stage hydrogenation activity while the C₂₊ selectivity increased from 14 C at% to 36 C at%. With the Al₂O₃ support, addition of K increased CH₄ decomposition activity but the C₂₊ selectivity increased only marginally. These results are discussed in terms of Co dispersion, support effects and the effect of K on the reactivity of the carbon species deposited during CH₄ decomposition.

Kinetics of the dehydrogenation of ethylbenzene to styrene over unpromoted and K-promoted model iron oxide catalysts

The dehydrogenation of ethylbenzene to styrene over unpromoted and potassium-promoted model iron oxide catalysts has been studied using ultrahigh vacuum techniques in conjunction with elevated pressure reaction kinetics. Model iron oxide catalysts were prepared by oxidizing a polycrystalline Fe sample that was subsequently dosed with metallic potassium. At 875 K the unpromoted catalyst exhibited a turnover frequency of 5×10^–4 molecules/ site s and an activation energy of 39 kcal/mol, both in excellent agreement with the results found for an analogous iron oxide powder catalyst. Potassium promotion increased the turnover frequency to 1.0×10^–3 molecules/site s and lowered the activation energy to 36 kcal/mol for the dehydrogenation reaction. Similarities between the activation energies on the unpromoted and promoted catalysts indicate that the active site is the same on both catalysts. Creation of the active site was dependent upon the formation of an Fe³⁺ metastable species, consistent with the formation of a KFeO₂ phase, upon the addition of potassium.     

Pricing, rebate, advertising and ordering policies of a retailer facing price-dependent stochastic demand in newsvendor framework under different risk preferences

This paper evaluates the pricing and ordering policies of risk‐neutral, risk‐averse and risk‐seeking newsvendor‐type retailers facing price‐dependent stochastic demand and several sales‐promotion policies, namely pricing, rebates and advertising. Optimal pricing and ordering policies are obtained for the iso‐elastic demand function and for additive and multiplicative demand‐error structures. Performance is measured by the risk‐adjusted expected profit and evaluated across risk preferences. Pricing, rebate and advertising, in that order, are the most profitable sales‐promotion policies. The more risk averse the retailer, the lower its profit and the more it favors multiple promotion policies.     

高等学校教学区建筑环境的空间整合

HIA practices in Nigeria

Health impact assessment (HIA) provides useful information on existing health services, their capabilities and the health status of the local communities, which is otherwise often unavailable. In Nigeria, HIA is usually applied to projects and, by exposing existing health inequities in project communities, provides the necessary tool for development proponents to act to provide or improve health services and to implement health promotion activities. Based on HIA experience in Nigeria, this paper highlights the deficiencies in national legislation with regards to HIA/EIA (environmental impact assessment) integration and a number of learning points are discussed. First, a complete health baseline is critical to the understanding of project impacts; analysis must be broad-based, considering existing health determinants. Second, community stakeholders and proponents may modify the implementation of health mitigation measures and should be seen as collaborators in the assessment process. Third, strong HIA recommendations can influence project design. A greater participation of the health sector in EIA is required to enhance HIA utilization.
