NON-USE OF CONTRACEPTION: DETERMINANTS AMONG UGANDAN UNIVERSITY STUDENTS


Tooth mineralization and histology patterns in extinct and extant snaggletooth sharks, Hemipristis (Carcharhiniformes, Hemigaleidae)-Evolutionary significance or ecological adaptation?

Shark jaws exhibit teeth that are arranged into distinct series and files and display great diversities in shapes and structures, which not only is related to their function (grasping, cutting, crushing) during feeding, but also bear a strong phylogenetic signal.So far, most research on the relationship between shark teeth and feeding ecology and s

Pattern analysis in a benthic bacteria-nutrient system

We study steady states in a reaction-diffusion system for a benthic bacteria-nutrient model in a marine sediment over 1D and 2D domains by using Landau reductions and numerical path following methods.We point out how the system reacts to changes of the strength of food supply and ingestion.We find that the system has a stable homogeneous steady sta
