Ecological effects of pesticides in freshwater model ecosystems

Popular Abstract in Swedish Bekämpningsmedel och algblomningar - finns det någon koppling? Inom det konventionella jordbruket används idag regelmässigt stora mängder bekämpnings-medel, bara i sverige spreds under år 2001 mer än 1700 ton kemiska bekämpnings-medel på åkrarna. Ett stort problem med användandet av dessa ämnen är risken att de sprids och förorenar den intilliggande naturen. De kan driIn this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. In the exposed enclosures the biomass of algae, heterotrophic nanoflagellates, ciliates and bacter

Music and Brain Plasticity

Complex and widespread activation in many brain areas is seen while performing, listening or mentally imaging music, activity that varies with training, previous exposure, personal preference, emotional involvement and many other factors. Playing a musical instrument demands extensive motor and cognitive abilities, and early musical learning results in plastic reorganization of the developing brai

The Role of the Disciples in the Prophetic Mission of Jesus

This article discusses what it meant for Jesus’ disciples to be disciples of a prophet and, consequently, what the presence of such prophet-disciples can tell us about his mission. This is done by situating the Gospel material about Jesus’ disciples in the context of early Jewish conceptions of prophetic discipleship, ultimately based on the Old Testament narratives about ancient Israelite prophet

Explicit Cache Management for Volume Ray-Casting on Parallel Architectures

A major challenge when designing general purpose graphics hardware is to allow efficient access to texture data. Although different rendering paradigms vary with respect to their data access patterns, there is no flexibility when it comes to data caching provided by the graphics architecture. In this paper we focus on volume ray-casting, and show the benefits of algorithm-aware data caching. Our M
