The aim of this thesis is to present a proposal for an evolved SQAD (Safety/Quality Assurance and Demonstration)-methodology. SQAD is a Safety Case-based methodology with the main purpose of supplying an effective tool for organizing and demonstrating system safety. Just as Safety Case, SQAD is designed to be a document that proves series of claims with the purpose to declare a system safe. This t
"The technology for planning and delivering radiotherapy has in the last decade undergone some revolutionary development and it is now possible to perform complex treatments such as stereotactic treatments and treatments using dynamic wedges, multileaf collimator and intensity modulation. The more precise limits surrounding the PTV have made it of utmost interest to be able to verify calculat
Objective: To evaluate the usefulness of magnetic resonance imaging (MRI) in predicting destructive rheumatoid arthritis (RA) in the knee joint, and to compare this method with clinical examination and conventional radiography (CR). Methods: Clinical evaluations of the knee joint, followed by MRI and CR examinations were performed in 30 patients with early RA. The MRI examination included evaluati
Purpose: This trial of the German High-Grade Non-Hodgkin's Lymphoma Study Group compares the use of high-dose therapy (HDT) as part of primary treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus etoposide followed by involved-field (IF) radiotherapy in a randomized, multicenter, phase III study. Patients and Methods: Three hundred twelve patients with "aggressive"
Thefirst reported applications of laser sheet imaging for the study of atomizing sprays date from the mid 1980th.Since those early tries, blurring effects from the light being scattered multiple times by the surrounding dropletswere already observed and reported. While s trategies in suppressing part of this multiple light scatteringcontribution, were known for transmission imaging (e. spatial Fou
The higher vibrational levels of the C 1s→π* excitation in carbon monooxide (CO) were investigated by using resonant Auger electron spectroscopy. The absorption profile of the CO was recorded in the partial electron yield mode. The results showed that the vibrational states were not seen in a total yield absorption spectrum whereas they were shown to be discernable in a partial electron yield spec
One of the more frequently applied methods for integrating controls on primary production through satellite data is the Light Use Efficiency (LUE) approach. Satellite indices such as the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and the Shortwave Infrared Water Stress Index (SIWSI) have previously shown promise as predictors of primary production in several dif
BACKGROUND: The planning target volume in radiotherapy treatment planning takes into account both movements of the clinical target volume (CTV) and set-up deviations. MATERIALS AND METHODS: A group of patients who received radiotherapy for lung cancer were studied. In order to measure the CTV movements due to respiration and other internal organ motions, fluoroscopy was performed for 20 patients.
Correlations between heterozygosity and fitness are frequently found but rarely well understood. Fitness can be affected by single loci of large effect which correlate with neutral markers via linkage disequilibrium, or as a result of variation in genome-wide heterozygosity following inbreeding. We explored these alternatives in the common buzzard, a raptor species in which three colour morphs dif
Increasing efforts to produce power from renewable resources and improve the efficiency of current industrial processes have turned the spotlight on organic Rankine cycles (ORC). The use of refrigerant mixtures in these cycles offers a wide range of possibilities for fluid selection and optimization. Moreover, zeotropic mixtures are reported to yield better cycle performances due to their better t
In this paper, a numerical study of flow, reactions and NOx emissions from a biomass boiler is presented. Detailed reaction mechanisms for the decomposition of tar species, combustion of hydrocarbons and formation of NOx are employed by adopting appropriate reaction sets from literature. The proposed mechanism is used to perform CFD simulations of a laboratory-scale biomass boiler, and temperature
Climate change has emerged as the most prominent of the global environment issues and there is a need to evaluate its impact on the agriculture. General Circulation Models (GCMs) which are considered as the most advance tools for estimating future climate change scenarios operate on coarse resolutions. It is for this reason the climate change model MAGICC coupled to SCENGEN developed by the IPCC w
The study tries to look at the impact of microfinance on the lives of the extreme poor people. There are different views on microcredit/microfinance as a powerful development tool regarding its success in developing the lives of the extreme poor and sometimes these views are contradictory. The purpose of the study was to observe the social and financial changes that have occurred also with an effo
Get married is the rite of passage that coincides with exit from the parental household, solemnizing the establishment of a new household and commitment to a sexual partner (Allan, G. et al, 2003:135), which is a ubiquitous phenomenon across human society. Almost all adult men and women seek to marry or form a permanent stable relationship with another person for the sake of bear children and rais
Definition: The Mbuluzi River runs through Swaziland and Mozambique into the Indian Ocean. Due to water shortage, population increase and growing industrial and agricultural sectors, high stress is being put on the water quality. The importance of keeping good water quality is accentuated by the fact that the River is shared between two countries and that it supports both capitals with drinking wa
In 2009, the BergaåsenWater Supply Scheme was put into operation to ensure the future drinking water supply of two municipalities in southern Sweden. Bergaåsen replaced two vulnerable water treatment plants. It was implemented in an environment that was characterized by sensitive recipients and limited access to water. This article aims to analyze how strategies were developed to meet sustainabili
Background: Research on eldercare has been dominated by a provider-oriented perspective, concerned with the conditions and views of care providers. There are striking differences compared with the field of disability studies, where help is framed as part of a larger project of having a daily life and being included in society. Pilot interviews indicate that older people develop active strategies t
Buildings Post Corona is a Swedish collaborative research project between Chalmers, KTH Royal Institute of Technology, Lund, and Umeå Universities. The project intends to provide knowledge related to designing, maintaining and operating sustainable buildings with a healthy and good indoor environment.The project aims to contribute to the knowledge and processes needed for the construction and real
