Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. However, one drawback is that these liquids are often very complex, which is a disadvantage when using membrane technology as it makes the

The aim of this thesis is to generate a theory of renewal in organizations. In modern society, characterized by the idea of progress, renewal has become an axiomatic assumption behind organizational existence. From an institutional perspective, the continuous search for new organizational forms and practises can be described as a process of imitation. The thesis acknowledges renewal as a process o

This doctoral dissertation has aimed to contribute to a modern theory of the firm that balances a disciplining view of the firm with an enabling view of the firm. This has been approached through exploring how corporate governance mechanisms influence entrepreneurship at the organisational level, in a frame of property rights. As such, the research model that guides the dissertation depicts a mode

This doctoral dissertation is a study on analogy-based arguments in law. Its overarching aim is to clarify reasoning by analogy in law. A model is proposed for analyzing and assessing arguments from analogy in law. The dissertation shows how analogy-based arguments in law proceed, what form they can be given and separates different steps involved in assessing whether such arguments establish the a

Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. A consequence is that power system damping is reduced, leading to a risk of poorly damped power oscillations between the generators. This thesis proposes the

We believe in managers and we believe in learning. Not least, we believe in managerial learning. Further, the dominant conception is that managers, through reflection on experience, develop an increasingly sophisticated understanding of their work, which in turn renders increasingly skillful managerial actions. Metaphorically, this learning trajectory can be described as a journey from stupidity t

The use of enzymes for synthetic applications is an area of increasing interest. Enzymes have been pointed out to be an environmentally friendly alternative to existing chemical methods, as well as making completely new synthetic routes possible. Over the last decades, much focus has been put on the enzyme group oxidoreductases, which can selectively introduce oxygen and hydrogen into molecules. T

Many vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils. Differences between calc

A number of results related to the geometric interpretation of some dispersive nonlinear wave equations are presented. It is first described how some well-known shallow water equations arise geometrically as Euler equations for the geodesic flow on the Virasoro group endowed with certain right-invariant metrics. For one of these equations?the Camassa-Holm equation?we demonstrate how geometric meth

I undertake a metaphysical investigation of Saul Kripke's modern classic, Naming and Necessity (1980). The general problem of my study may be expressed as follows: What is the metaphysical justification of the validity and existence of the pertinent classes of truths, the necessary a posteriori and the contingent a priori, according to the Kripke Paradigm? My approach is meant to disclose the log

The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone

In this dissertation I make a constructive contribution to a Christian spirituality for late modern religiously plural society. The words ‘a constructive contribution’ designate the methodological approach of the study. The words ‘late modern religiously plural society’ include the combination of social, political, cultural and economic factors in relation to which the question of spirituality wil

Sommaren 1945 fördes tusentals överlevande från koncentrationslägret Bergen-Belsen till Sverige i en räddningsaktion genomförd av United Nations Relief and Rehabilitation Administration (UNRRA) i samarbete med Svenska Röda Korset och svenska myndigheter. Folke Bernadottes omtalade vita bussar var inte den enda svenska humanitära insatsen vid denna tid. Mottagandet av de medtagna och ofta sjuka ind

In what follows, two properties characterizing supplier selection methods, namely, transparency and independence of irrelevant alternatives, will be properly discerned. Consecutively, three hypotheses, concerning the impact these properties have on the procurement outcome, will be suggested. Transparency is presumed to decrease the likelihood of having a locally established winner as well as to in
