The use of a multispectral imaging system provides possibilities to map all information encoded in the spectral fingerprint of an exogenous or endogenous chromophore in biological media. The spectral information has been used to demarcate the spatial extent of superficial skin tumours. Monitoring the fluorescence emitted from the photosensitizer over time yield information about the photodynamic t
Antioxidants are important molecules that are widely used by humans, both as dietary supplements and as additives to different types of products. In this chapter, we review how flavonoids, a class of polyphenolic antioxidants that are often found in glycosylated forms in many natural resources, can be extracted and modified using glycoside hydrolases (GHs). Glycosylation is a fundamental enzymatic
The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. We have focused on the cleavage specificities of HIV-1 protease, HCV NS3 protease and caspases on short oligopeptides or in native prote
We propose a technique for test scheduling and design of test bus infrastructure where test application time and test bus length and width are minimized while constraints on power consumption and test resources are considered. Our approach is suitable for repeated use in the design space exploration process due to its low computational cost. For the final design, we use simulated annealing to opti
A collection of original chapters focusing on young people and their political involvement, their use of the internet and other new media for learning the roles and practices of various forms ofcitizenship. The collection is analytically framed by the current dilemmas of democracy
In the autumn of 2011, the course “The City: Boundary Transgressions and Visual Expressions” was given for the first time. Formally placed at the Division of Art History and Visual Studies, the course is a collaboration with the Division of Social Anthropology and is directed towards students from a range of disciplines within the fields of the humanities and social sciences. The course includes
Sustainability has been on the agenda for decades. Yet it is not evident that the development we are witnessing can qualify as sustainable. Departing from an understanding of the adoption of sustainability as an on-going, unfinished process the thesis explores conditions for sustainability in Swedish transport infrastructure policy and planning. The study covers decision processes of three mega-pr
Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy. However, to fulfil the potential of anaerobic digestion in
The studies in this thesis have shown that the partitioning of endoglucanase I (EGI, Cel7B) from T. reesei could be significantly improved by relatively minor genetic engineering. By adding short peptides composed of tryptophan and proline residues to EGI, extreme partitioning could be obtained. The site of the tag fusion was shown to be crucial for the efficiency of the tag. Methods suitable for
A full-scale in-line primary sludge hydrolysis experiment was conducted in one out of four primary settlers at the Klagshamn Wastewater Treatment Plant (WWTP) to test if the wastewater quality can be improved in terms of providing easily accessible carbon for possible pre-denitrification and the reduction of external carbon sources. The amount of easily accessible carbon produced, in the form of t
Faster-than-Nyquist (FTN) signaling is a trellis coding method that maintains the error rate while reducing signal bandwidth. The combined effect is to move closer to capacity. We study some basic receiver issues: How to model the signaling efficiently in discrete time, how much the Viterbi receiver can be truncated, and how to combine the method with an outer code. The methods are modeling for mi
With an increasing interest for dynamic hygrothermal calculation models for short time periods, there is a need for uncomplicated and reliable methods to determine the moisture properties for materials used in the indoor environment. The traditional cup-method is commonly used for building materials to determine the water vapor permeability. When used on lightweight and highly permeable materials,
Affordable and competitive industrial automation is of key importance for small and medium enterprises, in Europe and elsewhere. A key factor is the introduction of new robot automation concepts that ease fast deployment and extend available task repertoire. The Gantry-Tau manipulator is a new robot concept. In contrast to other parallel kinematic manipulators (PKMs), it has a large working range.
Architects have a key role to play when it comes to the design of future low-energy (solar) buildings. Proper design tools and working methods could help architects in the design process. In order to identify barriers of existing tools and methods for solar design, needs of architects for improved tools, and to gain an insight into architects’ methods of working during the design process, an inter
