We aimed to study trends in gender-related differences in incidence, and prevalence for tong-term oxygen therapy due to chronic obstructive pulmonary disease. Another aim was to study survival after onset of oxygen therapy. Prospectively followed were 5689 Swedish patients, who were prescribed oxygen therapy because of chronic obstructive pulmonary disease from 1987 to 2000. The annual incidence o
An approach to teaching calorimetry is offered through practical, versatile undergraduate experiments using an isothermal heat conduction calorimeter, which measures a variety of heat changes--enthalpies of phase changes, hydration, dissolution, adsorption and desorption, and reaction--as well as the metabolic rate of living organisms. Isothermal heat-conduction calorimetry is contrasted with adia
Aims: The increasing number of people on disability pension in Sweden is of concern for Swedish policy-makers, and there is a need for a better understanding of the mechanisms behind disability pension. We investigated ( i) whether women living in the same neighborhood have a similar propensity for disability pension that relates to neighborhood social participation, and ( ii) whether there is an
Source-sorted municipal organic waste collected from different dwelling types in five Danish cities and pre-treated at three different plants was sampled and characterized several times during one year to investigate the origin of any differences in composition of the pre-treated waste introduced by city, pre-treatment technology, dwelling type or annual season. The investigated pre-treatment tech
Wastewater treatment plant operators encounter complex operational problems related to the activated sludge process and usually respond to these by applying their own intuition and by taking advantage of what they have learnt from past experiences of similar problems. However, previous process experiences are not easy to integrate in numerical control, and new tools must be developed to enable re-
This study uses the Swedish register of prescribed drugs, merged with the Survey of Living Conditions (the ULF), to analyze the socioeconomic gradient in drug utilization. It finds a significant education gradient (but no income gradient) in individual drug utilization. Whereas the education gradient for men is quantitative in its orientation (education affects number of drugs used), the gradient
In Australia a national public/private telematics framework has been established, which is administered by Transport Certification Australia (TCA). The first application was the Intelligent Access Program (IAP), which has enabled several road transport reforms by managing infrastructure risks associated with the operation of extra heavy vehicle configurations. The paper uses the IAP to demonstrate
Popular Abstract in Swedish Inflammerat brosk i halsen. Rethosta eller andningsbesvär. Autoimmuna sjukdomar uppstår när immunförsvaret angriper och bryter ner den egna kroppens vävnader. Då kroppen infekteras av bakterier eller virus är immunförsvarets ökade aktivitet däremot en normal skyddsmekanism. Exempel på vanligt förekommande autoimmuna sjukdomar är diabetes, reumatoid artrit (RA) och multRelapsing polychondritis (RP) and rheumatoid arthritis (RA) are autoimmune diseases where an inappropriate immune response destroys cartilage. In RP, the ears, larynx, nose and joints are affected, while the most prominent sign of RA is arthritis. For ethical reasons many experiments can not be performed in man, and consequently animal models are needed. To investigate the complexity of the tissu
Various papers described mesh morphing techniques for computational biomechanics, but none of them provided a quantitative assessment of generality, robustness, automation, and accuracy in predicting strains. This study aims to quantitatively evaluate the performance of a novel mesh-morphing algorithm. A mesh-morphing algorithm based on radial-basis functions and on manual selection of correspondi
A strategy for feedback control of the glucose feed rate in cultivations of E.coli is discussed. By making probing pulses in the feedrate it is possible to detect and avoid undesirable by-productformation using a standard dissolved oxygen sensor. The feasibility of an improved and simplified probing algorithm is demonstrated by simulations as well as laboratory-scale experiments.
This thesis is based upon four original papers describing the characterisation of mantle cell lymphoma (MCL) tumours and cell lines in comparison with different populations of normal B cells. Gene expression profiling, which were used in the studies, has during recent years developed as an important tool in characterisation of different types of malignancies. In this thesis, the technique is used
Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. Lignocellulose hydrolyzate contains not only sugars, but also several compounds, such as furfural and 5-hydroxymethyl furfural (HMF), which can inhibit yeast growth and ethanol produc
Modern military multi-role combat aircrafts need an emergency power system (EPU) to maintain back-up power supply for all normal and degraded flight modes. The reason for this requirement is that modern combat aircrafts are designed with built-in relaxed or negative stability. Inability of the Flight Control System to perform continuous, corrective control surface actuation, due to loss of power
