Few families of tournaments satisfying the n-e.c. adjacency property are known. We supply a new random construction for generating infinite families of vertex-transitive n-e.c. tournaments by considering circulant tournaments. Switching is used to generate new ne.c. tournaments of certain orders. With aid of a computer search, we demonstrate that there is a unique minimum order 3-e.c. tournamen...
We consider bidirectional cooperating distributed (BCD) grammar systems in the sense of Asveld. Independently of their mode , , =, , or t, BCD grammar systems with two components characterize the re-cursively enumerable languages even with right-linear rules and without-productions. This sharply contrasts earlier results on solely generating or accepting grammars, where right-linear rules alway...
Helping to reduce vulnerability poses a new set of challenges for public policy. A starting point is understanding the ways that communities and extended families try to cope with difficulties in the absence of public interventions. Coping mechanisms range from the informal exchange of transfers and loans within families and communities to more structured institutions that enable an entire comm...
Measurement results contain different kinds of uncertainty. Besides systematic errors andrandom errors individual measurement results are also subject to another type of uncertainty,so-called emph{fuzziness}. It turns out that special fuzzy subsets of the set of real numbers $RR$are useful to model fuzziness of measurement results. These fuzzy subsets $x^*$ are called emph{fuzzy numbers}. The m...
background: accidents, such as domestic accidents, and the resulting injuries are presently a matter of concern in communities. some factors such as urbanization cause an increase in the incidence of accidents for recognized and unrecognized reasons. the aim of the present study was to investigate the incidence of domestic accidents among a group of families who had migrated to the determined u...
We present a general method of operational nature to analyze and obtain solutions for a variety of equations of mathematical physics and related mathematical problems. We construct inverse differential operators and produce operational identities, involving inverse derivatives and families of generalised orthogonal polynomials, such as Hermite and Laguerre polynomial families. We develop the me...
available on-line contains supplemental material with the sequences of the unigenes predicted from P. infestans and a comparison of the frequencies of Pfam domains in predicted proteins from P. infestans, Neurospora crassa, and Arabidopsis thaliana. e-Xtra*
This study summarizes the State policy with respect to the determination of need in the Federal-State program of AFDC. The areas discussed are the individual State definitions of need, the content of need standard, the types of persons included in the payment, the amount of income and resources allowed recipient families, the method of determining need, and a comparison of State food allowances...
In the field of occupational hygiene, researchers have been working on developing appropriate methods to estimate human exposure to pesticides in order to assess the risk and therefore to take the due decisions to improve the pesticide management process and reduce the health risks. This paper evaluates dermal exposure models to find the most appropriate. Eight models (i.e., COSHH, DERM, DREAM, ...
