To obtain more information about muscle function in patients with dysphagia, simultaneous barium swallow and computerized pharyngeal manometry with solid-state pressure transducers was employed for the evaluation of the pharynx and the pharyngoesophageal segment (PES) in 30 consecutive patients. The manometry catheter was positioned under fluoroscopic control, providing localized measurements of t
An experimental technique with which to measure the fracture stress of fused curd grains, submerged in ultrafiltered milk permeate, has been developed and applied to curd grains of rennet-induced skim milk at pH 6.40 during the first 25 min of fusion. Effects of applied compressive stress within the range of 25-50 Pa, syneresis time, fusion time and tension loading rate were investigated. Fracture
In this article, different approaches to the field of urban ecology are distinguished. The focus lies on the approach characterized by looking at the city as an ecological system, since this view has given rise to the most fruitful discussion from a social geographical perspective. Further, references are made to four studies of applied urban ecology with short summaries of the most important conc
Water-soluble hemicelluloses were extracted from spruce chips by heat-fractionation using microwave treatment. A screening of conditions (pH, temperature and residence time) was performed for the extraction of O-acetyl-galactoglucomannan (AcGGM). The yield and the average molecular weight of the extracted mannan were analysed using HPLC, size-exclusion chromatography (SEC) and mass-spectrometry. T
Popular Abstract in Swedish Denna avhandling handlar om energieffektiva fönstersystem i svenska byggnader. Simuleringar av energianvändningen har gjorts för både småhus och kontor för att bedöma effekterna av olika fönsterval på energibehov och inneklimat. Två års mätningar av energianvändning och innetemperaturer för ett energisnålt radhus har utvärderats. Två beteendestudier har även genomförts This thesis deals with energy-efficient windows in Swedish buildings. Parametric studies were performed in the dynamic energy simulation tool Derob-LTH in order to study the effects of window choices on energy use and indoor climate for both residential and office buildings. A steady-state program was used to evaluate two years of measurements of energy use and indoor temperatures of an energy-eff
Despite modern advances in the treatment of head and neck cancer, the survival rate fails to improve. Considering the different treatment modalities involved, quality of life has been thought of as an additional end point criterion for use in clinical trials. A Nordic protocol to measure the quality of life of head and neck cancer patients before, during, and after treatment was established. Befor
Inflammatory bowel disease (IBD, i.e. primarily Crohn's disease and ulcerative colitis) is characterised by a chronic or relapsing inflammation of the digestive tract. The thiopurine drugs 6-mercaptopurine (6-MP) and azathioprine (AZA, an imidazol derivative and pro-drug of 6-MP) are currently used to an increased extent in IBD, particularly in Crohn's disease. Metabolism of thiopurines is comple
The aim of this study was to explore possible regional differences in the use of coercion in psychiatric care as experienced by patients and relatives. At four psychiatric care settings in different parts of Sweden, 138 committed and 144 voluntarily admitted patients were interviewed at admission using the Nordic Admission Interview. At discharge or, if the care episode was still ongoing, after 3
We study a model of the atrioventricular node function during atrial fibrillation (AF), for which the model parameters can be estimated from the ECG. The proposed model is defined by parameters which characterize the arrival rate of atrial impulses, the probability of an impulse choosing either one of the two atrioventricular nodal pathways, the refractory periods of these pathways, and the prolon
Aims. The present study was conducted to determine the optical extinction curve for Cerro Paranal under typical clear-sky observing conditions, with the purpose of providing the community with a function to be used to correct the observed spectra, with an accuracy of 0.01 mag airmass(-1). Additionally, this work was meant to analyze the variability of the various components, to derive the main atm
The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation
Urbanisation and industrialisation has led people spending more time indoors than ever before. Many buildings have small windows and contain large windowless spaces. Therefore, the natural daylight outdoors has to be replaced by light from artificial sources. If light affected vision only, this situation would be difficult enough. Since light also affects both well-being and health, the design of
A head and neck cancer specific questionnaire module designed to be used in quality of life assessments before, during, and after radiotherapy and surgery, with or without combinations with chemotherapy has been developed in accordance with guidelines given by the EORTC Quality of Life Study Group. Relevant issues were generated by means of literature search, and interviews with specialists and pa
Aims: A hip fracture is commonly regarded as the most devastating fragility fracture, as regards both morbidity and mortality, while a vertebral fracture is usually regarded as having lower general morbidity. The purpose of this study was to investigate whether hospitalized patients with a hip or a vertebral fracture experience similar functional deterioration following the fracture as regards act

The article consists in a presentation of endovascular surgery for abdominal aortic aneurysm repair in 23 cases. Two cases required conversion to open surgery, but the procedure could be completed in the remaining 21 cases, with a current duration of follow-up of up to 30 months. There was early leakage in one case, and late leakage in five cases. Late conversion has been necessary in three instan
Many children with cerebral palsy have feeding difficulties. The aim of this study was to investigate if trunk and neck positioning influenced oral and pharyngeal swallow. Five children with feeding problem aged 3-10 years with cerebral palsy were examined using videofluoroscopy. All children had tetraplegia with dystonia, i.e. poor head control and poor trunk stability. All children had gross asp
Popular Abstract in Swedish Pappersbrott i planet har studerats med hjälp av den kohesiva sprick modellen ur ett experimentellt såväl som ur ett teoretiskt perspektiv. Brott i en pappersremsa erhålls när remsan i en provmaskin belastas till sin maximala bärlast. Om remsan är tillräckligt kort fås en stabil nedåtgående last-förlängnigs kurva efter det att max lasten är nådd. Det visade sig att denThe in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone
Critical systems must comply with safety standards in many application domains. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system’s lifecycle, and impact analysis might be necessary to guarantee that system safety and compliance are not jeopardised. Although extensive rese
