Behandling av artros. Etiologi och patofysiologi vid artros - terapeutiska konsekvenser

Artros (i engelskt språkbruk ”osteoarthritis”, ibland ”osteoarthrosis”) är en sjukdom med sakta förlopp och ibland gradvis försämring. Sjukdomen kan leda till total förstöring av leden och behov av operation med ersättning av leden med konstgjort material. För de flesta patienter med artros blir kirurgisk behandling dock aldrig nödvändig, besvären kan behandlas bra på annat sätt.Artros är inte en

Measured and predicted behaviour of steel beams and columns in fire

Analytical predictions of mechanical behaviour of fire-exposed steel structures are compared to experimental results obtained from three different research laboratories. Comparisons are made to axially free and restrained steel columns fire tested in Metz in France 1973-74, to simply supported steel beams fire tested in Germany and published in Stahlbau 1/1983 and to axially free and restrained st

Chemiluminescence of 1,2-dioxetane. Reaction mechanism uncovered

The thermal decomposition of 1,2-dioxetane and the associated production of chemiluminescent products, model for a wide range of chemiluminescent reactions, has been studied at the multistate multiconfigurational second-order perturbation level of theory. This study is in qualitative and quantitative agreement with experimental observations with respect to the activation energy and the observed in

Epicardial right atrial free wall mapping in chronic atrial fibrillation. Documentation of repetitive activation with a focal spread--a hitherto unrecognised phenomenon in man

BACKGROUND: Previous studies have shown that atrial fibrillation of recent onset in man is based on a varying number of simultaneously present activation waves reentering either themselves or each other. In the present study, right atrial activation during chronic atrial fibrillation in man was studied. METHODS AND RESULTS: In 16 patients with chronic atrial fibrillation multiple epicardial record

Evaluation of low-energy tailing parameters of a HPGe X-ray detector to be used in GUPIX software library for PIXE analysis

Accurate description of the response function of X-ray detectors is important for quantitative PIXE analysis. For analytical description of low-energy tailing in PIXE spectra, the GUPIX approach was used, i.e. a combination of Hypermate type functions. The low-energy tailing parameters of a low-energy high purity germanium X-ray detector in the region 1.3-9.2 keV was determined by systematic fitti

Low body mass of juvenile Ross's gulls Rhodostethia rosea in the Laptev Sea

Four juvenile Ross's gulls Rhodostethia rosea were trapped on the New Siberian Islands in the Laptev Sea in early August 1994, allowing data collection on body mass and morphometrics from a poorly known part of the species' annual cycle. The wings of juvenile birds were shorter than those previously reported for adults, but their bill length and tarsus length were similar. Their average body mass

Arkitekten Hans Westman, funktionalismen och den regionala särarten

Popular Abstract in Swedish Arkitekten Hans Westman var verksam i Skåne från 1932 till 1983. Hans rika och mångskiftande produktion har satt sin prägel på den moderna skånska arkitekturen, särskilt i Lund där han hade sitt arkitektkontor. Westmans arkitektur spänner över ett brett fält från bostadshus, offentliga byggnader, kraftverk till kyrkor och kloster. Flera verk är välkända, t ex radhusområThis thesis deals with the regional aspects of Swedish modernism exemplified by the architecture of Hans Westman (1905-1991). The main purpose of the dissertation has been to make a survey of what is perceived as particularly regional in Westman's buildings and if we can really talk about modern regional architecture. Modernism's breakthrough brought about the introduction of an architecture which

Popular Abstract in Swedish Syftet med studien har varit att, genom huvudsakligen kvalitativ beskrivning, studera narrativ sekvens, d v s berättelsen, i exolingvala samtal mellan infödd och icke infödd (svensktalande studenter) talare av franska. Den teoretiska ramen sträcker sig från textlingvistik (Revaz, Adam, Bronckart etc.) till konversationsanalys (Labov, Sacks, Norrick, Laforest, Kerbrat-OrThe aim of this study is to examine, through a mainly qualitative description, the narrative in exolingual conversations in French between non-native speakers (NNS) (Swedish students) and native speakers (NS). The theoretical frame ranges from text linguistics (Revaz, Adam, Bronckart etc.) to conversation analysis (Labov, Sacks, Norrick, Laforest, Kerbrat-Orecchioni, Bres, Norrby etc.). The study

Tissue transglutaminase autoantibodies in childhood celiac disease

Popular Abstract in Swedish Bakgrund - Glutenintolerans (celiaki) är en vanlig kronisk tunntarmssjukdom som drabbar 1% av befolkningen och beror på att man inte tål ämnet gluten som förekommer i vete, korn och råg. Celiaki är delvis ärftligt och förekommer i alla åldrar, men upptäcks framför allt hos barn. Intoleransen mot gluten orsakas av en immunologisk reaktion mot tunntarmens slemhinna som efCeliac disease is a prevalent small bowel disease in children caused by permanent intolerance against gliadin, which is the alcohol-soluble fraction of the cereal protein gluten in wheat, rye and barley. Celiac disease is characterized by an inflammatory infiltrate of CD4+ T lymphocytes in the intestinal mucosa leading to damage of villous structure and loss of absorptive surface. As a consequence

Empirical Evaluations of Usage-Based Reading and Fault Content Estimation for Software Inspections

Empirical evaluations in software engineering are important in order to build a body of knowledge of methods that work in different environments. This thesis presents six empirical investigations of two techniques applied to software inspections, namely reading techniques and fault content estimation techniques. The first part of the thesis presents a series of experiments of a novel reading tech

In search of the talkative public: Media, deliberative democracy and civic culture

Theories of democracy consider communicative interaction among citizens central, In recent years the idea of deliberative democracy has galvanised elements of political theory with perspectives on communication. This concept emerges to a large extent from the Habermasian trajectory and links currents from theories of civil society and citizenship. It has thus a rather forceful normative dimension.

Kernels and multiple windows for estimation of the Wigner-Ville spectrum of Gaussian locally stationary processes

This paper treats estimation of the Wigner-Ville spectrum (WVS) of Gaussian continuous-time stochastic processes using Cohen's class of time-frequency representations of random signals. We study the minimum mean square error estimation kernel for locally stationary processes in Silverman's sense, and two modifications where we first allow chirp multiplication and then allow nonnegative linear comb

Time-Updating Discrete-Time `Analytic' Signals

The discrete-time 'analytic' signal finds numerous applications in a wide range of fields, and call be efficiently implemented using the fast Fourier transform (FFT). A computationally efficient sliding window time-update of the discrete-time 'analytic' signal, not requiring the FFT, is proposed.

Validity and reliability of triaxial accelerometers for inclinometry in posture analysis

There is a need for objective and quantitative methods for measuring posture and movement, so that, for instance, exposure-response relationships for work-related musculoskeletal disorders can be established. Inclinometry data have been obtained from triaxial accelerometers based on uniaxial solid-state accelerometers used in conjunction with a computer program to perform co-ordinate transformatio
