Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. The synthesis of PCP-ligands include new and improved preparative routes to the previously known cis-1,3-bis-(di-iso-propylphosphinito)cy

Investigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. In this thesis tools from statistical physics are used to study different aspects of DNA confined to nanochannels, with particular regard to its denaturation properties. The study of DNA melting from the theoretical

This thesis investigates the origin of children's literature in China and traces its evolution in connection with the author Zhang Tianyi, who is officially considered as one of the forerunners of Chinese children's literature. Children's literature in China is a little studied field, although the sources for a study are abundant. The thesis studies children's literature in its social context, whi

The aim of this work was to quantify limitations of and uncertainties in commonly used dosimetric techniques for relative absorbed dose determination in degraded electron beams, such as those encountered in intraoperative radiation therapy (IORT) and small-electron-field radiotherapy. Three different detector types were investigated with regard to measurements of output factors and relative absorb

Title: Rules, roles and risks- A study on occupational health and safety in the construction sector Author: Tova Westerlund Supervisor: Radhlinah Aulin Examiner: Anne Landin Aim & goal: The purpose of this report has been to investigate occupational health and safety risks in the construction sector, how responsibility roles relate to these risks, and the impact of Arbetsmiljöverkets regulatio

The accuracy of dose calculations for various aspects of a treatment planning system (TPS) using an energy fluence beam modelling has been evaluated. The investigated TPS uses a beam model, which separates the energy fluence into a number of sources in the treatment head. The energy fluence components are transported towards the patient and, together with the scatter generated in the patient, yiel

Most animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. They have a limited nervous system, but they also possess a visual system that is quite impressive for a jellyfish. Box jellyfish have 24 eyes

Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. This is made possible by use of conspecific signals picked up by one or several sensory systems, the most well investigated bei

Artificial intelligence is breaking new grounds each year and one of the most promising and extensively researched area of study in the field is the artificial neural networks. In this project, artificial neural networks are designed to help medical staff in estimating at an early stage what risk a patient has of developing serious postoperative complications after having undergone an oesophageal

This master’s thesis centers on the meetings on one organization, the Fredsbaskrarna or Peace Berets. Its purpose it to reveal and analyze the interactions, conversations and narratives at these meetings. Fredsbaskrarna is an interest organisation started by military veterans, where local meetings and face-to-face interactions are of central importance. The concrete research questions are: Which e

Idrott, piller, sprutor, blodtransfusioner och avtalsrätt. Det övergripande syftet med uppsatsen är att utreda hur dopning regleras i Sverige och om denna reglering är rättsenlig i förhållande till avtalsrätten. En specificering av det övergripande syftet är att undersöka regleringen utifrån de avtalsrättsliga krav som ställs för att villkor ska anses inkluderade i ett avtal och således bindande f

The chronic problem of music piracy is inevitable with the utilisation of the internet. Music, being classified as information good, makes the consumer to “free-ride” and sub-optimal production of these goods is likely to happen. Copyright is an instrument in helping the continuity of creative activity. The essence of copyright law is also to protect the interests and rights of the writers, produc

The assembly of respiratory chain complexes in the mitochondrial inner membrane requires specific factors. Once assembled to form a mature functional complex, complex III (CIII) is a dimer consisting of two monomers, each with eleven subunits. To date, seven assembly factors for CIII are known, of which BCS1L incorporates the Rieske iron-sulfur protein (RISP) in the last stage of the assembly. The

This thesis offers an investigation of the literary form and the literary composition of The Ladder by John Climacus, as well as a study of how the author uses the tradition to form his reader. Besides a brief introduction with a survey of the previous research, the study comprises four chapters. In the first chapter it is shown, from a number of detailed text analyses, that the material in the s
