It's not over till it's over.
Case studies are presented of three HIV-infected patients, one heterosexual, one bisexual, and one homosexual, who continued to engage in unsafe sex. Western countries have seen an increase in unsafe sex practices since the early 1990s, raising the specter of a new wave of HIV infections. Increasing rates of sexually transmitted diseases are already being reported in case studies and by the Cen...
متن کاملGeochemical Partitioning in Till
and Vagners (1971, 1972) expressed this phenomenon elegantly by introducing the concept of "terminal mode" for the optimum grain size to which a mineral can be reduced, given the force and energy typically available in the glacial environment. Thus, hard, uncleaved or poorly cleaved minerals such as quartz, fcldspar, garnet, pyrite and magnetite dominate either the medium or the fine sand fract...
متن کاملA numerical study of glacier advance over deforming till
The advance of a glacier over a deforming sediment layer is analysed numerically. We treat this problem as a contact problem involving two slowly-deforming viscous bodies. The surface evolution of the two bodies, and of the contact interface between them, is followed through time. Using various different non-linear till rheologies, we show how the mode of advance depends on the relative effecti...
متن کاملOptimizing Strip-Till and No-Till Systems for Corn
Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...
