Statistical and block copolymers for anion-exchange membranes with high local concentrations of quaternary ammonium groups

Cationic polymers in the form of anion-exchange membranes (AEMs) may enable a route towards low platinum or even platinum-free alkaline membrane fuel cells with the potential to oxidize more complex fuels than hydrogen and methanol [1-4]. The main challenges for the AEMs are currently to enhance the alkaline stability of the cationic group and to improve the ion conductivity. In this context, ther

Initialization of the Kalman Filter without Assumptions on the Initial State

In absence of covariance data, Kalman filters are usually initialized by guessing the initial state. Making the variance of the initial state estimate large makes sure that the estimate converges quickly and that the influence of the initial guess soon will be negligible. If, however, only very few measurements are available during the estimation process and an estimate is wanted as soon as possib

Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants

This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. They were characterized genetically, physiologically and biochemically. Degradation of nonylphenol by Bjerkandera sp. strain BOL13 and

Developing Codes of Conduct: Regulatory Conversations as Means for Detecting Institutional Change

The introduction of a new corporate governance code in Sweden, modeled after prevailing Anglo-Saxon norms of corporate governance, offers the opportunity to investigate global regulatory convergence. Using the metaphor of regulatory space, this article analyzes the positions of the parties who submitted formal responses to the introduction of "The Swedish Code of Corporate Governance-A Proposal fr

Setting the Marketing Scene: Reality Production in Everyday Marketing Work

Popular Abstract in Swedish I den litteratur om marknadsföring, som vanligen används på universitet och högskolor, framställs ofta marknadsföringsarbete som något som äger rum i en objektivt given värld, vilken kan observeras, diskuteras och studeras som ett ”faktum” utanför och mer eller mindre oberoende av företaget och dess aktiviteter. I denna avhandling är utgångspunkten istället att det vi uThe aim of this thesis is to offer a contribution to the understanding of marketing work. In orthodox, mainstream marketing management literature, the work of marketing is commonly depicted as a fairly straightforward practice, technical in character, neutral in terms of social values and ideologies, operating within an objective and pre-given world. A counter picture to this idealised view of mar

Nazismens sensmoral : Svenska erfarenheter i andra världskrigets efterdyning

At the core of this study is an enquiry into the experiences of Nazism and the conclusions that were drawn from them. The prime concern is the ideological and intellectual arena in Sweden in the wake of the Second World War, but throughout the study the Swedish case is examined against a more general international background. In recent years, many international scholars have turned their interest

Effects of dopamine and excitotoxicity in experimental models of Huntington's disease

Popular Abstract in Swedish Denna avhandling handlar om en ärftlig hjärnsjukdom som heter Huntingtons sjukdom, eller danssjuka. Sjukdomen leder till personlighetsförändringar, ofrivilliga rörelser (som ser ut som om personen dansar) och demens. Personer som drabbas dör 15-20 år efter att symptomen har brutit ut, och en god behandling eller botemedel saknas. Sjukdomen orsakas av att HuntingtongenenHuntington's disease (HD) is a hereditary neurodegenerative disorder caused by an expansion of a CAG repeat in the HD gene, that leads to dysfunction and death of striatal neurons. The pathogenetic mechanisms underlying HD are not known, but excitotoxicity and dopamine (DA) have been suggested to play a role. In this thesis, the effects of excitotoxicity and DA have been studied in striatal in vit

Vetenskap, evighet och religion; en studie i Anders Nygrens religionsfilosofi

Anders Nygrens ambition was to develop a criterion by which he could distinguish between science and non-science. This is th K(v) of Nygren. According to Nygreb tgere are three ways of arguing in science which all fullfill the demand of K(v): a) deductive argumentation b) empirical argumentation and c) philosophical argumentation. a) and b) operate at the material level and c) at the formal one. c
