Degradation of wood polysaccharides by fungal glycoside hydrolases

The enzymatic degradation of wood polysaccharides such as cellulose and hemicellulose is an important process in nature. In addition, cellulases and hemicellulases can be used in industrial applications. Fuel ethanol can potentially be produced from wood by enzymatic hydrolysis of cellulose followed by yeast fermentation of the formed sugars. In this thesis, fungal glycoside hydrolases, cellulase

Total Cost Indicators - Operational Performance Indicators for managing environmental and economic efficiency

In this Licentiate Dissertation presents a new model for selecting environmental performance indicators in order to improve environmental management. The suggested Total Cost Indicators support a support a preventive approach to environmental management, where environmental issues are addressed before they arise - and before they become costs. The method of selecting indicators builds on earlier

Ruin probabilities and first passage times for self-similar processes.

This thesis investigates ruin probabilities and first passage times for self-similar processes. We propose self-similar processes as a risk model with claims appearing in good and bad periods. Then, in particular, we get the fractional Brownian motion with drift as a limit risk process. Some bounds and asymptotics for ruin probability on a finite interval for fractional Brownian motion are derive

Structure, Morphology, and Catalytic Properties of CuOx/CeO2 Model Catalysts

Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. To study the catalytic oxidation of CO, we have synthesised model CuOx/CeO2 catalysts by gas phase tec

Jewish Perspectives on Law and Religion in the Nordic Countries in the 21st Century

An introduction to Judaism as text-centered traditions and conceptions of law, along with an outline of the Jewish legal history, is given as frame for a more specific presentation of the history of the Jews in the Nordic societies up to modern times with Denmark as the main example, including potential problems such as ritual slaughter and circumcision. The close relationship between Jewish law a

Supported-liquid membrane extraction

Supported-liquid membrane (SLM) extraction is a miniaturized version of liquid–liquid extraction (LLE), involving a hydrophobic membrane containing an organic solvent in the pores. Compared to LLE, it uses microliter-volumes of organic solvents, and provides high enrichment, outstanding clean-up and no emulsion formation. Here, basic principles and technical aspects as well as new developments in

A MATLAB toolbox for Robustness Analysis

Verification of control systems is often done using extensive simulation. This gives the engineer useful qualitative information about the system performance. However, simulation cannot be used to rigorously prove stability and robustness of the system. Such properties can only be verified using mathematical analysis which for many realistic systems becomes rather involved. This paper presents the
