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-
The distribution of 50 species in the south Swedish provinces of Skane (Scania). Halland, Blekinge, Oland and Smaland has been mapped. Many of the species are endemic to southern Scandinavia and some are local endemics within the investigated area. However, there are also several species with a wider North European distribution. Within the area, the number of species shows a regular decline from t
Popular Abstract in Swedish Information om smärta, klåda och temperaturförändringar förmedlas till centrala nervsystemet av tunna nervfibrer som leder nervimpulser relativt långsamt. Information om beröring av huden förmedlas istället av grova och snabbt ledande nervfibrer. Det är välkänt att olika känselkvaliteter kan interagera med varandra på olika nivåer i centrala nervsystemet. Vanlig berörinIt is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fie
Popular Abstract in Swedish Strålningsterapi är en viktig metod för att behandla många cancertyper och man söker konstant efter olika sätt att förbättra användningen av joniserande strålning vid behandling. Radiobiologisk forskning för cancerterapi söker att förbättra vår förståelse för hur joniserande strålning verkar på olika livsformer. Idag finns det många sätt att utröna en behandlings inverkFor the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. Two different detectors ’ Design A and Design B’ were fabricated with thi
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.
In mathematical education it is crucial to have a good teaching plan and to execute it correctly. In particular, this is true in the field of numerical analysis. Every teacher has a different style of teaching. This thesis studies how the basic material of a particular topic in numerical analysis was developed in four different textbooks. We compare and evaluate this process in order to achieve a
With sustainability at the forefront of many cities’ urban development plans, it is possible that sustainable polices are targeted to attract a certain group of inhabitants. Malmö, Sweden, has implemented changes in order to gain international recognition as a green city but has also been experiencing growing residential segregation. The presence of urban greening projects is a keystone to human h
The increased capacity of elementary particle accelerators raises the demand for the simulation data of the experiments. One of the bottlenecks in the simulations is the QCD color structure calculation, which is usually treated using non-orthogonal and overcomplete sets of bases. The computational cost could be decreased significantly if orthogonal bases, such as the multiplet bases, were used ins
Purpose: The purpose of this study is trying to understand which elements are essential to obtain loyalty in the alcoholic beverage industry and how companies can focus their branding efforts on these drivers of loyalty. Methodology: A literature review is conducted to identify the key drivers which can influence brand loyalty. These drivers are then analysed by researching two case studies, Hein
