Organism response to toxic compounds is routinely tested in highly controlled laboratory tests conducted under rigorous standards (AMERICAN PUBLIC HEALTH ASSOCIATION [APHA] et al. 1976, AMERICAN SOCIETY FOR TESTING AND MATERIALS, 1980). Toxicants are rarely present in nature in singular doses, and stresses on particular organisms may come from a variety of natural and anthropogenic sources. A n...

In this Chapter, we study networks of locally coupled Wilson-Cowan (W-C) oscilla-tors [Wilson and Cowan, 1972]. The W-C oscillator is a two variable system of ordinary differential equations and represents an interacting population of excitatory and inhibitory neurons. The amplitudes of the variables symbolize the proportion of each population of neurons that is active. We study these equations...

Paludrine, N1-p-chlorphenyl-N5-isopropylbiguanide acetate, was found by British workers to be ;he most active antimalarial of a series of synthetic guanidines and biguanidines (1, 2). It possesses high activity against the erythrocytic asexual parasites of both vivax and falciparum malaria and is practically non-toxic at therapeutic doses (3, 4). Previous study of the compound has included exte...

This paper proposes to explore how being “skillful” (mergen) plays out and is relied upon in Mongolia within two different contexts, archery divination, both linked “cairns” (ovoo) more than one way. In these skillful people are expected embody a virtue that any Mongolian man or woman supposed exhibit daily less spectacular consequential manner. As prominent bearers of skillfulness, archers div...

CAIRNS, S.D., 1989:10:30. Discriminant analysis of Indo-West Pacific Flabellum. Mem. Ass. Australas. Palaeontols 8, 61-68. ISSN 0810-8889. Stepwise discriminant analysis was performed on 145 specimens of Indo-West Pacific Flabellum pertaining to 8 putative species. Posterior classification supported the premise of 8 species at the 99.3% level. Only two characters are needed to distinguish all s...
