The effect of traces of hydrogen sulphide and of sulphur dioxide on the oxidation of methane over supported precious metals has been examined. Both gases inhibited catalytic oxidation over Pd and Rh, apparently as a result of sulphate f...

Enterobius vermicularis is the most common helminthic infection in Western Europe and in the US. Here the author describes a case of an asymptomatic patient with Enterobius infection as an incidental finding at colonoscopy. This article...

It is shown that if a cyclotomic m-class association scheme of order q contains no k-clique then it is possible to find an edge-coloring of Km(q+1) into m colors containing no monochromatic Kk+1. This leads to greatly improved lower bou...

A pragmatic framework is available for maintaining reliable system operations in the context of an unbundled open access environment, while fostering a competitive supply/demand market. The proposed framework shows how incentives will m...

We analyze the Bell polynomials Bn(x)Bn(x) asymptotically as n→∞n→∞. We obtain asymptotic approximations from the differential-difference Chi Hair Straightener Uk equation which they satisfy, using a discrete version of the ray ...

A nationwide brewing industry study provided an opportunity to empirically test, for the first time, the construct “supplier's desire to influence.” The relationships between desire to influence and perceived use of both coercive an...

The paper shows ICPET-SA activity results in the thermopower equipment and installations rehabilitation and repowering field: steam boilers, electrotatic precipitators, steam turbines, electrical generators and burning systems for indus...

For the r-stage open shop problem with identical parallel machines at each stage and the minimum makespan criterion, an approximation scheme is constructed with running time O(nrm+C(m,ε)), where n is the number of jobs, m is the total ...

The elastic constants of crystalline graphite are calculated from a fairly simple model. The bending and stretching force constants of the carbon-carbon bonds, along with the crystal geometry, determine the elastic compliances. The key ...
