A series of x(Co, Mn)/TiO2 catalysts (x=2–12wt.%) containing 25%Co and 75%Mn were prepared by the co-impregnation method. All prepared catalysts have been tested in Fischer-Tropsch synthesis for production of C2-C4 olefins. It was found that the catalyst containing 8wt.%(Co,Mn)/TiO2 is an optimal catalyst for production of C...

In order to obtain more accurate predicted dynamic steady-state performance with shorter computation time, an available mathematical model is modified and presented. Using this modified model, performance of a typical switched reluctance motor (SRM) under a wide range of variations of operating conditions is obtained and discussed. These include variations of speed, voltage, load and switching ...

Removal of cesium from synthetic aqueous solution through adsorption on vermiculite, under batch equilibrium experimental condition at six initial values of pH (3, 4, 6, 9, 11 and 12) and five temperatures (25, 50, 75, 85 and 95 °C) has been investigated. It is necessary to propose a suitable model for a better understanding of the mecha...

BACKGROUND Improved sanitation has been shown to have great impacts on people's health and economy. However, the progress of achieving the Millennium Development Goals (MDGs) on halving the proportion of people without access to clean water and basic sanitation by 2015 has thus far been delayed. One of the reasons for the slow progress is that policy makers, as well as the general public, have ...

Euclidean n-component φ theories whose Hamiltonians areO(n) symmetric except for quadratic symmetry breaking boundary terms are studied in the film geometry R×[0, L]. The boundary terms imply the Robin boundary conditions ∂nφα = c̊ (j) α φα at the boundary planes Bj=1 at z = 0 and Bj=2 at z = L. Particular attention is paid to the cases in which mj of the n variables c̊ (j) α associated with plan...

Increased attention has been paid recently to the issue of the regulation of professional boundaries. In this paper, we undertake an international comparison of the regulation of health professional boundaries across the OECD countries of Canada, the U.S., the U.K. and Australia. Our case studies focus on the inter-professional boundary negotiation between medicine and nursing and the intra-pro...
