In this paper, Kekule structures of benzenoid chains are considered. It has been shown that the coefficients of a B_n (x) Morgan-Voyce polynomial equal to the number of k-matchings (m(G,k)) of a path graph which has N=2n+1 points. Furtermore, two relations are obtained between regularly zig-zag nonbranched catacondensed benzenid chains and Morgan-Voyce polynomials and between regularly zig-zag ...

The validity of the dark adaptation test for showing mild degree of a deficiency of vitamin A is now generally acknowledged. Thus Harris and Abbasy') found that impaired dark adaptation was common in children whose diet was estimated to be low in vitamin A while it was rare in well nourished children. There are, however, many contradictory reports2 3) concerning the effect of vitamin A on the d...

Due to the intensification of poultry sector, manure is being produced in increasing quantities, and its on-site management becoming a critical problem. Animal health problems can be solved by stricter veterinary environmental standards. The off-site coupled industrial chicken recycling technology (Hosoya compost tea) fundamentally affects agricultural value new organic-based products. limited ...

THIS special section is dedicated to the three Best Papers of VRST 2009, which was held in Kyoto, Japan from 18 to 20 November 2009. The papers were first selected by a jury based on the referees’ reports and the oral presentation. The authors were then asked to provide an extended version. The extended papers were then reviewed through a strict peer review process. The first paper, “Robust Rel...

In contrast to other approaches to (2+1)-dimensional quantum gravity, the Wheeler-DeWitt equation appears to be too complicated to solve explicitly, even for simple spacetime topologies. Nevertheless, it is possible to obtain a good deal of information about solutions and their interpretation. In particular, strong evidence is presented that Wheeler-DeWitt quantization is not equivalent to redu...

During the past decade, remarkable progress has been made in understanding the interactions between the immune system and cancer. Importantly, there is growing evidence for the concept of cancer immunosurveillance and immunoediting based on (i) protection against development of spontaneous and chemicallyinduced tumors in animal systems and (ii) identification of targets for immune recognition o...
