This works deals with the degradation of a group of recalcitrant compounds known as toxaphene. Toxaphene is a complex mixture of chlorinated compounds including hexa- and octachlorocamphenes, hepta-, nona- and decachlorobornanes. Some components of toxaphene are very persistent while others are degraded rapidly by both abiotic and biotic processes. Not all components of toxaphene have been identif

Popular Abstract in Swedish Så gott som alla djur i naturen utgör ett potentiellt byte för rovdjur. Bokstavligt talat är det därför livsviktigt att försöka undvika att bli upptäckt och fångad av sina naturliga fiender. Då olika arter exponeras för olika typer av rovdjur (predatorer) är det kanske inte så konstigt att det finns en enorm variation av försvarsstrategier i naturen. Mer förvånande är kPredation imposes a potent evolutionary force on prey, moulding the evolution of traits and diversification of species, and can furthermore have powerful ecological consequences. We know that different species vary in how they cope with their natural enemies, and, consequently, a huge range of anti-predator defences are displayed in nature. Yet there is a growing recognition that, if we zoom into

Abstract in UndeterminedAn analytical model of dune erosion was developed based on impact theory, where the weight of eroded material is assumed proportional to the impact force from waves hitting the dune. The model was validated with data from several laboratory and field studies on dune erosion covering a wide range of hydrodynamic, sediment, and geometric conditions. Overwash was then included

A number of medieval visions of the otherworld have been preserved in writing. This article studies six such visions from the seventh to the twelfth centuries. Whereas most studies focus on what such visions have to say about hell and purgatory, this study focuses on what they have to say about heaven.

Short essay on Ingmar Bergman's Vargtimmen (1968)

This dissertation reports on a study of reform processes in public organisations. It describes how two municipalities planned and attempted the introduction of the purchaser-supplier model. This type of reform reflects one important contemporary idea - that of the market as an all-encompassing institution. The study focuses on the very process of reforming, with the aim of providing an alternative

An introduction to the avantgarde films of Swedish-German writer and filmmaker Peter Weiss (1916 - 1982)

This Ph.D. submission deals with contemporary demonstration culture and political activism, seen as performance through performance. It consists of both a practical and a theoretical part. These are intertwined on various levels of the project. My submission, however, is made up of the two following parts: 1: A textual part, divided into 8 parts. Each part contains a script, an analysis and a nu

Idag utvecklas inom olika områden nya tänkesätt och handlingsmönster som bygger på helhet, integration och fokusering av flöden. I framtiden kommer konkurrensen att ske mellan olika kedjor av företag, inte mellan enskilda företag. Traditionella organisationsgränser och mål är i dessa nya sammanhang av underordnad betydelse. De nya tänkesätten gör förädlings-/försörjningskedjan mer effektiv. De in

This thesis deals with the growth, processing and characterization of nano-sized structures, eg., self-assembled quantum dots and nano-wires. Such structures are promising candidates for the realization of nano-scale electronic and optical devices, like for instance single electron transistors, resonant tunneling devices, and single photon emitters. For such purposes, the main focus of this work h
