Cytochrome P-450 monooxygenases in the mosquito, Culex pipiens

Creator:: Baldridge, Gerald D.
Abstract:: A sucrose density-gradient ultracentrifugation technique for obtaining microsomes has been developed. This technique has advantages over the classic differential centrifugation technique, in that it is faster, is better suited to work with small quantities of tissue, and offers the opportunity to work with a defined microsomal sub-cellular fraction, rather than...

Behavioral adaptations and the minimization of reproductive costs in the male red-sided garter snake, Thamnophis sirtalis parietalis.

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

Using p-adic valuations to decrease computational error

Creator:: Limmer, Douglas J.
Abstract:: The standard way of representing numbers on computers gives rise to errors which increase as computations progress. Using p-adic valuations can reduce error accumulation. Valuation theory tells us that p-adic and standard valuations cannot be directly compared. The p-adic valuation can, however, be used in an indirect way. This gives...
