Enzymes and mechanisms for violaxanthin-zeaxanthin conversion

The xanthophyll cycle is of great importance in relation to light stress. Particularly, interest has been focused on the possible photoprotective role of zeaxanthin. In higher plants under light stress, zeaxanthin is formed from violaxanthin in a reaction catalyzed by violaxanthin de-epoxidase (VDE). The reverse reaction is catalyzed by zeaxanthin epoxidase (ZE) under low light or in darkness. VDE

Dynamic Communication: an Analytic and Constructive Study on the Problem of Religious Communication, based on Martin Buber's Philosophy of Dialogue

Popular Abstract in Swedish I avhandlingen "Dynamisk dialog: en analytisk och konstruktiv studie av den religiösa kommunikationens problem på grundval av Martin Bubers dialogfilosofi" studerar jag olika aspekter av Bubers modell för hur en människa meningsfullt kan kommunicera sin religiösa upplevelse till och med en annan människa. Min metod har både en begreppsanalytisk och en fenomenologisk sidIn the present work, I study various aspects of Martin Buber's model of how a human being can communicate, in a meaningful way, his or her religious experiences to and with another human being. My method has aspects of both conceptual analysis and phenomenologial description. I focus on the individual partners, their mutual relationships and the religious message. Buber's model is based on the con

Palladium-Catalysed Syntheses of 3-Substituted Indoles and Hetero Analogues

3-Substituted indoles and their analogues - hetero condensed pyrroles (hetero-indoles) - have been synthesised by two different palladium-catalysed reactions: a) A series of 2-silylated 3-substituted (hetero-)indoles have been prepared by palladium-catalysed coupling between o-iodo(het)arylamines and silyl substituted internal acetylenes. The outcome of the reaction was found to depend on the typ

Born globals’ foreign market channel strategies

Foreign entry mode choices are decisions of paramount importance for the long-term survival and growth of companies that are in a process of rapid international expansion. In this article we seek to understand the foreign market channel strategies of Born Globals. We examine whether these companies develop a similar strategy regarding foreign entry mode choices and if their market channel strategi

Natural Products as Leads for Pharmaceutically Active Compounds

In the search for new pharmaceutically active compounds, it is recognized that Nature produces structurally different compounds in a great variety. By having the compounds or extracts tested in defined systems, new drugs or more often leads (a compound that has an interesting but moderate activity) can be found. When a lead is found, structurally similar compounds with modified functional groups a

Dynamics of Energy Systems - Methods of analysing technology change

Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. Two types of methods have been considered, methods of analysing and proje

Conceptual Spaces at Work in Sensory Cognition : Domains, Dimensions and Distances

This chapter makes use of two data sources, terminological schemas for wine descriptions and actual wine reviews, for the investigation of how experiences of sensory perceptions of vision, smell, taste and touch are described. In spite of all the great challenges involved in describing perceptions, professional wine reviewers are expected to be able to give an understandable account of their exper
