Performance analysis of cell zone partitioning in bandwidth reservation schemes

Bandwidth reservation is a procedure that can be applied to give higher priority to certain connection types in cellular networks. Subscriber movement predictions can be used to determine the amount of bandwidth to be reserved in each cell. The prediction accuracy is significantly unproved if both the approximate subscriber locations in the cell and stored subscriber movement data are taken into a

The effects of crayfish on interactions in freshwater benthic communities

Popular Abstract in Swedish Kräftors påverkan på födovävar i dammar och sjöarThis thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus). Overall, the results show that both crayfish species are omnivores having strong direct and indirect effects o

Bioactivity of Medicinal Bolivian Andean plants. Effects on cell proliferation and related processes.

Popular Abstract in English Bolivia is the seventh richest country regarding biodiversity in the world. Also, in its territory more than 36 indigenous nations co-exist. Each of these has traditional medicines that are passed on from generation to generation orally. It has been estimated that the Bolivian flora has more than 20,000 plant species. Some of these are being explored for their pharmaceuColon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. In these studies, phytochemicals have proven to be good sources for drug dis
