We consider a problem of dispersing points on disjoint intervals on a line. Given n pairwise disjoint intervals sorted on a line, we want to find a point in each interval such that the minimum pairwise distance of these points is maximized. Based on a greedy strategy, we present a linear time algorithm for the problem. Further, we also solve in linear time the cycle version of the problem where...

Highly efficient exfoliation of individual single-walled carbon nanotubes (SWNTs) was successfully demonstrated by utilizing biocompatible phenoxylated dextran, a kind of polysaccharide, as a SWNT dispersion agent. Phenoxylated dextran shows greater ability in producing individual SWNTs from raw materials than any other dispersing agent, including anionic surfactants and another polysaccharide....

Hypothesis: Dispersal outside a local population maintains population density below the possible maximum, but within a single local population selection acts against dispersal and consequently against such maintenance. Individuals that disperse exhibit lower fitness that is correlated with their smaller body size. Organism: Laboratory populations of Tribolium confusum beetles. Methods: Four con...

A theoretical model is proposed for explaining the recently observed modal dispersal of polarization information and its recovery in an experiment in which the coupling dispersing fiber. to the phase conjugator is by means of a (multi)mode dispersing fiber.

Faba bean gall (FBG) is a devastating disease of faba (Vicia faba) in Ethiopia. Studies were undertaken first to compare and contrast similarities between FBG symptoms morphology Ethiopia with those reported earlier China and, secondly, identify definitively the causal agent, previously considered as Olpidium viciae, through molecular studies. Morphological studies confirmed an epibiotic phase ...

The controlling kinetics of the water solubility of two synthesized mono azo naphthalimide based disperse dyestuffs in the presence of two different dispersing agents namely Irgasol DAM and lyoprint EV agents at various temperatures were investigated. An exponential rate equation was found to describe the dissolution process. The addition of Irgasol DAM and Lyoprint EV dispersing agents increas...

Bird damage control often involves dispersing birds from areas where they cause problems. Dispersal techniques have been used at airfields, rural and urban bird roosts, livestock facilities, fruit orchards, grain fields, and other locations. Certain avian vocalizations have evolved as alarm or distress calls, and these calls can be exploited as a means of dispersing birds. The behavioral respon...
