Two algebraic number fields are arithmetically equivalent when their zeta functions coincide. This paper provides a method for comparing the ideal class groups of arithmetically equivalent fields K, K′. In particular, bounds are obtained for the variance of the class numbers hK, hK′.
The colorimetric assay procedure of Prescott and Jones ((1969) Anal. Biochem.32, 408–419) has been modified to make the standard curve more consistently linear. Improved results are obtained when the assay tubes are exposed to yellow light at an intensity of 45–50 fc (480–540 lx) during color development. Somewhat longer incubation times are required for color development with yellow light.
This study presents preliminary findings of a brief friendship-based HIV/STI prevention intervention for urban African American youth. Using Nike Yeezy 2 Red
a no-control design, we found that the program is feasible, acceptable, and demonstrates promise with regard to Basket Nike Air Max Pas Cher changes in HIV/STI-related knowledge, beliefs, social norms, and behavior.
It has become apparent in recent years that unexpectedly large numbers of minisatellites exist within the eukaryotic genome. Their use in genetics is well known, but as with any new class of sequence, there is also much speculation about their involvement in a range of biological processes. How much is known of their biology?
