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
Stream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. The first attack is performed on SOBER-t16 and SOBER
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
This thesis concerns a religious actor in the civil society in times of violent conflict. During the British Mandate period in Palestine, Jewish, Muslim and Christian children studied together at Anglican missionary schools. At this time Jerusalem bore all the imprints of ethnic and religious separation and division. The Anglican educational project became part of the efforts made by the Anglican
The aim of this dissertation is to discuss the two theologic anthropological concepts microcosm and steward within the World Council of Churches project called the JPIC-process - their JPIC stands for justice, peace and the integrity of creation - and to relate the two anthropological concepts to each other using a theological correlation method. After an introduction the JPIC-process, which offic
Traditional off-line programming is not enough in order to use the full potential of virtual models and simulation system in industrial robot applications. The interface between off-line programming system and the robot controller is today restricted to program transfer. In this way a large amount of information is lost since typical robot programming languages is rather limited. If the virtual m
The link between population mobility and environmental change is fundamental for our understanding of how future global environmental changes will affect our societies, and also how the increased mobility will change our role in the Earth system. Climate change has been predicted as a major cause of human migration, both voluntary and forced, through for example increased storm and drought frequen
This study explores the role of transcriptional regulation important in the development of L-DOPA-induced dyskinesia in a rat model of Parkinson’s disease. In patients with Parkinson’s disease, dyskinesia is one of the most difficult complications of the DA-replacement therapy by L-DOPA. The underlying mechanisms are still unknown, but a role of abnormal striatal plasticity has been proposed. The
The aim of this study is to gain knowledge and understanding of how nursing students experience and manage the different parts of the education. A particular focus is set on the tension between a professional degree and an academic degree, between theoretical and clinical studies, and between the subjects nursing and medical science. Furthermore, the aim is to gain knowledge and understanding of a
This thesis is devoted to the development and investigation of a supramolecular system used to catalyze Jacobsen-Katsuki epoxidations with the aim to attain substrate selectivity without product inhibition. The supramolecular catalyst is composed of two well-defined entities or units: a catalytic and a receptor. The keyword for the design was flexibility. The interactions foming the supramolecula
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
Isocyanates may cause occupational asthma, rhinitis, and hypersensitivity pneumonitis. However, the mechanisms behind initiation of the disorders and the relations between exposure and effect are insufficiently elucidated. Means to biomonitor exposure and risk would be valuable. A case, exposed to heated polyurethane, displayed metabolites of 4,4'-dipheylmethane diisocyanate in blood and urine, an
This doctoral thesis deals with consumers’ attitudes towards serving them-selves with machines rather than being served by personnel. Its aim is to contribute to the theory of perceived service quality by providing a better understanding of customers’ attitudes and preferences when using technology-based self-service. In addition to aspects of service dealt with by traditional service-quality rese
The research field of the thesis is clinical adult psychiatry and it focuses on the treatment of patients with autism spectrum disorders. Before the publication of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) in 1994 intellectually high-functioning patients with autism have not been included in diagnostic manuals and received appropriate treatment in adult psychiatry. In recent y
When Britain decided, in 1968, to terminate its official colonial presence in the Persian (Arabian) Gulf as of 1971, this action prompted the Gulf Arab States (Kuwait, Bahrain, Saudi Arabia, Qatar, United Arab Emirates, and Oman) to start the search for a form of partnership that would bring them together to better cope with the insecurity and danger surrounding them and their regimes. A key probl
Starch microsphere is a dosage form suitable for the encapsulation of protein drugs. The starch microspheres investigated in this thesis are intended for release of the drug in a pre-designed way, or in controlled manner. For this purpose the starch microspheres can be coated by poly(DL-lactide-co-glycolide) (PLG) film, which is a release controlling. The term microsphere quality is complicated an
