The adsorption of lipases to solid surfaces was studied by means of in situ ellipsometry. In addition, the activities of the adsorbed lipases were measured in situ, by the hydrolysis of p-nitro phenyl acetate. Adsorption was made to methylated silica surfaces with varying degree of wettability as well as to clean silica surfaces. Lipases from Humicola lanuginosa (HLL) ­ the wild-type (WT) and a m

The work presented in this thesis is mainly motivated by the need for an optical diagnostic technique which can be used to visualize hydrogen peroxide (H2O2) in its gas phase. Due to the lack of bound electronic states, H2O2 cannot be detected using laser-induced fluorescence based on electronic excitation. Absorption in the ultraviolet leads to photodissociation. Thus a technique called photofrag

This thesis focuses on different convolutional coding constructions for digital communication systems, and on methods to analyze these constructions. The work presented in the thesis can be divided into three main areas; error probability bounds for convolutional codes, analysis of multilevel modulation, and investigation of low-density parity-check convolutional codes. New bounds are developed f

All living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair

Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp. from heavily vegetated habitats in tropical fresh-water. Littorina a

The dissertation deals with two part-studies. The main focus is a field study the purpose of which is to understand incurable disease and death as hands-on experiences at the player's level. With the aid of observations and interviews, nine dying people, relatives and community nurses are followed in the families? homes over time. The second part-study is a discourse analysis of Danish health-poli

Large herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. Nevertheless, data in the less detailed form of annual censuses of large herbivore densities and weather i

The aim of the present study is to examine the polytypia (morphological variation) and semantic differentiations of the verb in Vitsentzos Kornaros' Erotokritos, to understand how these shape poetic style. We examine the stems and the endings in the imperfective active forms. Moreover, we investigate the augmented forms because at an early stage we found that Kornaros employs a degree of poetic li

The first purpose of this dissertation is to describe and discuss the development of the Iron Age society in Scania. The second purpose is to discuss the relations between Scania and the neighbouring areas. The Iron Age society was hierarchical and ruled by different types of leaders, usually cheiftains or kings. To maintain and develop the social system different social groups acted in society.

Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena th

The main aim of this thesis is to explore young women’s lived experience of the body, which, on one hand, is viewed as deviant – the disabled body – and, on the other hand, is viewed as accomplished – the sporting body. The questions posed in the thesis are the following: how do the young women handle the two subject positions that emerge as a result of the perception of them as respectively devia

Abnormal gastric motor function, a frequent complication among the increasing diabetic population of the world, also includes other patient groups such as those many patients with functional dyspepsia. These facts stress the need for a reliable, safe, cost-effective, and simple technique for measuring gastric emptying. To date the ultrasound technique for measuring gastric emptying has been regard

The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. Currently it is responsible for removing 25-30% of our emissions every year, an important ecosystem service that may not persist in the long term. Global warming tends to decrease the CO2 sink capacity of the world’s oceans and ecosystems leading to a larger fraction of our emiss

In this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases. The models studied

Nanowires have the potential to be a very flexible platform for the design of semiconductor devices. In nanowires it is possible to form crystal structures not found in the bulk materials under normal conditions, and to combine different III-V and group IV materials into axial or radial heterostructures. As quite complex structures can be formed, both intentionally and unintentionally, characteriz

The gram-positive bacterium Enterococcus faecalis is a commensal organism, often found in the gut of humans and other animals. It can cause opportunistic disease and it frequently causes nosocomial infections. Treatment of such infections is often impaired by this organisms broad intrinsic and acquired resistance to antibiotics. E. faecalis uses homo-lactic fermentation for energy production. Work

This thesis investigates how play may benefit creativity in organizational contexts. Play and playfulness have previously been linked to creativity in children and adults, but empirical organizational research is scarce. A widely accepted definition of creativity is that it involves the production of something that is both novel and appropriate. Play is defined as a behavioral approach that is cha

Nuclear medicine is based on the radiotracer principle of George de Hevesy and the magic bullet concept by Ehrlich and focuses on the diagnosis, the treatment of diseases and the investigation of normal states within the human body using radiopharmaceuticals. A radiopharmaceutical is an atom or a chemical compound in which one or several atoms are replaced with a radionuclide. Several diagnostic a
