Filosofisociologi : Ett sociologiskt perspektiv på filosofiskt tänkande

The subject matter of the present doctoral thesis is the sociology of philosophy, a sub-discipline within the general field of sociology. As the term clearly indicates, the sociology of philosophy concerns the sociological study of philosophy. As this domain is still, to some extent, virgin territory, my thesis is mainly explorative in nature. Viewed as a whole, it aims at investigating what a soc

On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis

The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). The basis functions of the sERP are the damped sinusoids where the frequency and damping factor are estimated from the signal. The algorithms for white noise disturban

Stealth radomes

This dissertation deals with periodic structures that are used as free-space electromagnetic filters. Two types of periodic structures are treated, namely the so called frequency selective surface (FSS) and the artificial puck plate (APP) structure. The FSS structure consists of one or several periodic arrays of identical elements embedded in an arbitrary number of dielectric layers. The APP struc

Mellan klient och rättssystem : Tvångsvård av barn och unga ur socialsekreterares perspektiv

This dissertation focuses on assessments concerning children and young persons in the Social Services. The aim has been to describe and analyse the compulsory care process from a social worker perspective, and to understand and explain how this affects the practice of child welfare. I have used case files from the Social Services and focus group interviews with social workers as empirical data. Th

DEGENERATIVE CHANGES OF THE HUMAN TEMPOROMANDIBULAR JOINT: A radiological, microscopical, histomorphometrical and biochemical study.

In five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage. The calcified cartilage was outlined by a flat or gently undulating basophilic tidemark and an irregular os

Continuum Mechanics Modelling of Corrugated Board

The storage of compressive loaded boxes in an environment with naturally varying humidity is a practical issue in corrugated board employment. Time dependent variables such as moisture content, strain fields, stress fields and material strength play important roles for the time to failure. Supplementary, the stochastic nature of material and moisture load is obstructing the prediction of a reliabl

Den välreglerade friheten: att konstruera det lekande barnet

The purpose of the thesis is to shed light on pre-school as an arena for governmentality, where play is a tool for governing the child. The study focuses what in play-situations may become an object of governance and what techniques the teachers use to govern the children when they play. The theoretical framework is the work of Foucault and his perspective on power and knowledge. The empirical stu

Automatic memory management for flexible real-time systems

In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. In order to make safe high-level languages, like Java, practical

Satellite remote sensing of primary production in semi-arid Africa

With the challenges Africa faces with respect to the predicted warming due to climate change, the continents role in the global carbon cycle has been increasingly recognized. Earth observing satellites have played a significant role in the study of vegetation, particularly in Africa where climate stations are sparse. Satellite data can provide the means to map plant primary production for monitori

Studies on chondroadherin-an extracellular matrix leucine-rich repeat protein

This thesis describes chondroadherin, one of the leucine-rich repeat proteins in the extracellular matrix (ECM) of cartilage. Chondroadherin defines a subgroup of its own by not having an N-terminal extension, having a different cysteine pattern and by being devoid of carbohydrate substitutions. Here we show that chondroadherin also have a different exon-intron organization and chromosomal localiz

Pharmacophore Refinement and Lead Optimization - A study of the benzodiazepine site of the GABAA receptors

Structure activity relationship studies of synthetic flavone derivatives have been utilized to refine and evaluate a pharmacophore model of the benzodiazepine binding site of the GABAA receptors, originally developed by Zhang et al. (Drug Des. Discovery 1995, 12, 193-248). In addition to the previously proposed pharmacophore elements, two steric repulsive regions have been added to the model and t

Green Colloid Chemistry: Characterization of Environmentally Friendly Nonionic Surfactant Systems

Phase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. NMR-self diffusion, cryoTEM and TRFQ experiments show the presence of long interconnect network

Robotic Friction Stir Welding for Flexible Production

Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. FSW is already widely adopted in several industries but the applications are limited to simple geometries like straight lines or circular welds, mostly in aluminium. The

Upper Extremity Musculoskeletal Disorders In Female Machine milkers - An Epidemiological, Clinical and Ergonomic Study

The aims of the thesis were to investigate the prevalence of the upper extremity musculoskeletal disorders in female milkers in relation to other occupational groups; to clarify the relationship between disorders and work environment, psychosocial and life style factors; to compare in a prospective study, pain, ache and discomfort reported by a questionnaire with clinical symptoms and sign; to exa

Quality Aspects of Modified Atmosphere Packaged Broccoli

The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package. This thesis has focused on the MAP of broccoli and the effect of the packa

Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy.

Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. In this thesis, methods for processing and analysis o

Creativity in the School Context

The main aim of the present investigation was to highlight middle childhood creativity, and the children’s perspective on creativity, in contrast to many, if not most, studies that investigate creativity from an adult perspective and a scholarly definition. This dissertation consists of two quasi-experimental studies, and one interview study. Study I investigated if, and how, state anxiety, brough

Human Beta-microseminoprotein expression, with special reference to gastric mucosa, atrophic corpus gastritis and gastric carcinoids

Human Beta-microseminoprotein is a 94 amino acid protein with 10 cysteins present in seminal plasma and on many mucosal surfaces in the body. The function of the protein is unknown. The purpose of this investigation was to study the distribution of Beta-microseminoprotein in the human body, especially in the stomach. The latter was studied under both normal and pathological conditions. A radioimmu
