Abstract in UndeterminedAccurately modelling the dynamic behaviour of multi-storey buildings in wood requires the geometry involved to be represented in great detail, resulting in systems having many millions of degrees of freedom. Consequently, there is a need for model order reduction and the methodology of substructure modelling is employed here to create reduced models for analysis of low-freq
Popular Abstract in Swedish Avhandlingen berör membranbaserade tekniker för provupparbetning, vilket enkelt uttryckt innebär att använda membran för att ”skilja agnarna från vetet”. De membran som använts kan designas för att vara selektivt genomsläppliga, d.vs. släppa igenom vissa molekyler och inte andra. Denna selektivitet behöver inte vara baserad på molekylstorlek, tvärtom styrs den mer av moComplex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. Use of membranes and especially non-porous membranes for extraction purposes offers in many cases the desired measure of selectivity and sensitivity for trace
Background: An increase in intestinal permeability and subsequent bacterial translocation has been demonstrated in critical illness. Cellulose derivatives have in the past been shown to reduce gut leakage following liver resection. Aims: The aim of the present study was to evaluate changes in microbial counts in experimental acute pancreatitis and the effect of pre-treatment with cellulose deriva
Four kitchens, each with a different work load, were used to evaluate the microbiological risk of utilizing blasting granules in a new type of warewash machine. The granules, plastic pellets 3.5 - 3.5 mm, are recirculated together with the dishwater in the machine, and when the dishwater is expelled, the granules remain in the machine until the next day. Samples of soiled dishwater and tap water w
There is increasing evidence that territorial stream fish populations exhibit some degree of self-thinning. Four size-limit strategies were examined, under which a size-structured model population exhibiting self-thinning was exploited. The effects of: (1) increased minimum-size limits; (2) protection of spawners; (3) decreasing maximum-size limits; and (4) slot limits (prescribe lower and upper s
The effects of the chaotrophic anion perchlorate (ClO4-) on glucose-induced electrical activity, exocytosis and ion channel activity in mouse pancreatic B-cells were investigated by patch-clamp recordings and capacitance measurements. ClO4- stimulated glucose-induced electrical activity and increased the action potential frequency by 70% whilst not affecting the membrane potential when applied in
A systematic assessment of radiotherapy for cancer was conducted by The Swedish Council on Technology Assessment in Health Care (SBU) in 2001. The assessment included an overview of the capacity for radiotherapy in terms of infrastructure of cancer care and an estimation of the costs of radiotherapy in Sweden. A postal questionnaire distributed to all 16 centres of radiotherapy in Sweden showed th
The brain lesions in stroke-prone spontaneously hypertensive rats (SHRSP) are characterized by multifocal microvascular and spongy-cystic parenchymal alterations particularly in the gray matter. An essential feature of the lesions is the presence of edema with massive extravasation of plasma constituents as evidenced by specific gravity measurements, Evans blue technique and immunohistochemistry.
Popular Abstract in Swedish Beslutsinkompetenta patienter behöver en ställföreträdande beslutsfattare som kan fatta vårdbeslut för deras räkning. En av de etiska frågor som aktualiseras i detta sammanhang är vilka riktlinjer som bör gälla för sådant beslutsfattande. Enligt ?the Substituted Judgment Standard? (SJS) bör en ställföreträdare fatta det beslut som patienten själv hade fattat, om denne hPatients who are incompetent need a surrogate decision maker to make treatment decisons on their behalf. One of the main ethical questions that arise in this context is what standard ought to govern such decision making. According to the Substituted Judgment Standard (SJS), a surrogate ought to make the decision that the patient would have made, had he or she been competent. Although this standard
English non-expressive, declarative sentence intonation is examined in a discourse context. A rule system, geared to a text-to-speech context is developed which assigns sentence prominences related to information focus. The realization of these prominences with respect to the phonetic parameter of pitch (F0) is also described with a pitch generating algorithm. The dynamics of information focus in
In a series of studies, the functional organization of cerebellar regions contributing to the control of forelimb movements via the rubro- and corticospinal tracts has been characterized in the cat. The system consists of the cerebellar cortical C1, C3 and Y zones and their efferent intracerebellar nucleus, the interpositus anterior. Based on analyses of cutaneous and muscle afferent climbing fibr
Intracellular lipid-binding proteins contain a large binding cavity filled with water molecules. The role played by these water molecules in ligand binding is not well understood, but their energetic and dynamic properties must be important for protein function. Here, we use the magnetic relaxation dispersion (MRD) of the water 17O resonance to investigate the water molecules in the binding cavity
Randomized controlled trials (RCTs) in palliative cancer care often experience methodological problems. In this paper we discuss issues of major concern, including recruitment, patient attrition and compliance, arising from an RCT that compared comprehensive palliative care to conventional care. The main criteria for trial entry were incurable malignant disease and a survival expectancy of between
Objectives. To compare the incidence of haemorrhagic stroke (HS), and the risk of fatal outcome after HS in patients with oral anticoagulation (OA) treatment and in the general population. Design. Five-year cohort study. Setting. The Anticoagulation Clinic, Malmo University Hospital, Lund, Sweden. Subjects. A total of 4434 patients treated with OA (6693 treatment years) from 1 Oct 1993 to 30 Sept
Abstract in UndeterminedCash-Flow-at-Risk (CFaR) is the cash flow equivalent of Value-at-Risk (VaR), a measure widely used as the basis for risk management in financial institutions. Whereas VaR-based systems specify the maximum amount of total value a firm is expected to lose under most foreseeable conditions (for example, with a 99% confidence level), CFaR-based systems determine the maximum sho
Introduction: The proportion of elderly patients who are undernourished is high and undernutrition has serious health implications. No consensus exists regarding nutritional screening measurements suitable for elderly patients. There is a need to identify risk factors for undernutrition in elderly patients to enable prevention and treatment. Aim: To identify clinically identifiable risk factors fo
We use a microscopic Slater-Koster tight-binding model with short-range exchange and atomic spin-orbit interactions that realistically captures generic features of ferromagnetic metal nanoparticles to address the mesoscopic physics of magnetocrystalline anisotropy and hysteresis in nanoparticle-quasiparticle excitation spectra. Our analysis is based on qualitative arguments supported by self-consi
Objectives. To record the occurrence of well-differentiated bladder carcinoma reported as T1 G1 to the Swedish Urinary Bladder Cancer Registry, to review the staging and grading of the carcinomas and to scrutinize the validity of the data on T1 G1 tumours reported to the registry during the period 1997-2000. Material and methods. The primary histopathological diagnoses of 98 cases of well-differen
Genotyping of Chlamydia trachomatis is limited by the low sequence variation in the genome, and no adequate method is available for analysis of the spread of chlamydial infections in the community. We have developed a multillocus sequence typing (MLST) system based on five target regions and compared it with analysis of ompA, the single gene most extensively used for genotyping. Sequence determina
