Popular Abstract in Swedish Hur påverkas djurplanktonsamhällen av klimatförändringar och vilken betydelse har vilostadier? Populärvetenskaplig sammanfattning av “Ecology of zooplankton communities: climate, dormancy and benthic-pelagic coupling”, doktorsavhandling i Limnologi vid Ekologiska institutionen, Lunds Universitet, 2003. Djurplankton är sjöars motsvarighet till betande kossor ochThis thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. A field experiment showed that the total biomass of both phytoplankton and zooplankton in

Research in theoretical chemistry is aimed at finding computational algorithms that produce as accurate results as possible, for as large molecules as possible, with a minimum of computational effort and to apply these methods to molecular systems of chemical interest. The most accurate theoretical methods, often referred to as ab initio methods, are derived from the fundamental laws of physics an

En genomgång av hur den bibliska gestalten Mirjam presenterats i rabbinsk litteratur och hur den senare använts och tolkats inom modern feministisk judendom.

During B lymphocyte development, the transcriptional activity of the IgH locus is subject to spatial and temporal changes. The 3' enhancer (3'E) has been suggested to play an important role in regulation of immunoglobulin gene expression late in B cell development. We have investigated, using transgenic mice, the role of the 3'E in regulating Ig gene expression. Mice harbouring a rearranged IgH ge

Den här uppsatsen skall undersöka några av företeelserna som har betydelse för ett skapande av en europeisk identitet och ett "gemensamt" Europa. Diskussionen om Europa som gemensam institution handlar oftast om ekonomiska svårigheter, sällan diskuteras t.ex. historiska, normativa, och kulturella mellanmänskliga och mellanstatliga dilemman i större sammanhang. Frågan jag ställer i uppsatsen tar ju

This article presents a linear, iterative method to solve the eye-to-hand calibration problem between a wrist-mounted laser scanner and the tool flange of a robot. Measurement data are acquired from a set of non parallel planes whereafter the plane equations and desired rigid transformation matrix are found in a two-step, iterative fashion. The method is shown to handle large error in the initial

A gas-phase method has been developed for producing size- and composition controlled nanoparticles of binary alloys. The constituent elements are evaporated sequentially, with size selection after the first and second stages. In this paper, we study the Au-In system in compositions ranging from pure Au to 70 atomic percent In. Transmission electron microscopy was used to study morphology and struc
