Neurogenic Inflammation: Additional Points

William Meggs's recent article, "Neuro-genic Inflammation and Sensitivity to Environmental chemicals" (EHP 101:234-238), provides a useful introduction to a rapidly growing area of knowledge in physiology and posits a number of interesting hypotheses regarding the health effects of airborne chemicals. Some specific technical points, however, merit comment. Meggs describes the common chemical se...

SOME POINTS ON CASIMIR FORCES

Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...

Some Identities Relating to Eulerian Polynomials and Involving Stirling Numbers

In the paper, the authors establish two identities, which can be regarded as nonlinear differential equations, for the generating function of Eulerian polynomials, find two identities for the Stirling numbers of the second kind, and present two identities for Eulerian polynomials and higher order Eulerian polynomials, pose two open problems about summability of two finite sums involving the Sti...
