FOUR TAPEWORMS AT ONCE.

Arcs Intersecting at Most Once

We prove that on a punctured oriented surface with Euler characteristic χ < 0, the maximal cardinality of a set of essential simple arcs that are pairwise nonhomotopic and intersecting at most once is 2|χ|(|χ|+1). This gives a cubic estimate in |χ| for a set of curves pairwise intersecting at most once on a closed surface. We also give polynomial estimates in |χ| for sets of arcs and curves pai...

On Existing All at Once

e nature of divine eternality is obscure in both historical andmodern discussions. In a way its obscurity is no surprise, given that the nature of time is so mysterious. But the obscurity is still notable relative to the other traditional divine attributes, which are comparatively much better understood. Our perplexities regarding eternality are compounded, I will argue here, by a failure to re...

Evaluation of Microsatellites Markers to Discriminate Four Main Taeniid Tapeworms of Dogs

BACKGROUND Echinococcus granulosus, Taenia multiceps, Taenia ovis and Taenia hydatigena are among the most prevalent taeniid species of dogs. These tapeworms infect ruminant and humans as intermediate hosts and domestic/wild carnivores as the definitive hosts. Molecular tools using hypervariable microsatellite regions might provide more information about parasite variation. Highly variable and ...

How Many Parts to Make at Once

Every manufacturer is confronted with the problem of finding the most economical quantity to manufacture in putting through an order. This is a general problem and admits of a general solution, and, however much it may be advisable to exercise judgment in a particular case, such exercise of judgment will be assisted by a knowledge of the general solution. The writer has seen the practical worki...
