Digital image correlation (DIC) can measure full-field surface strains during mechanical testing of hard and soft tissues. When compared to traditional methods, such as strain gauges, DIC offers larger validation data (similar to 50,000 points) for, e.g., finite element models. Our main aim was to evaluate the repeatability of surface strain measurements with DIC during compressive testing of comp
The performance of eight fast-response methane (CH4) gas analysers suitable for eddy covariance flux measurements were tested at a grassland site near the Cabauw tall tower (Netherlands) during June 2012. The instruments were positioned close to each other in order to minimise the effect of varying turbulent conditions. The moderate CH4 fluxes observed at the location, of the order of 25 nmol m(-2

Of 1774 children (aged 10 to 11), screened for obesity, 44 obese children were divided into two treatment groups. In an untreated control group of 50 obese children, screened in the same manner, body mass index (BMI
Gm allotypes are genetic variants of the immunoglobulin heavy G chains (IGHG) of IgG molecules, coded from chromosome 14q32, characterized by differences in amino acid epitopes of the constant heavy G chains and inherited in the Mendelian manner. Gm allotypes have influence on IgG subclass levels, and serum Gm allotype levels have been given for different Gm genotypes in adults. Four hundred and t
It has been demonstrated that prostate-specific antigen (PSA), in spite of its name, can be detected in body fluids and tumors from a variety of organs. Investigations have shown that human glandular kallikrein 2 (hK2), a related prostate-secreted protease, can activate the zymogen form of PSA, suggesting that the two enzymes might work as a functional unit, with hK2 as the activator molecule and
Popular Abstract in Swedish Under 1920-talet och framåt accelererade moderningseringsprocessen på många plan och det svenska samhället kom att allt mer förändras. Följande studie handlar i mycket om hur man på olika sätt kan förhålla sig till den nya tid som kommer. Gertud Lilja var verksam mellan 1924 och 1964. Under 1920-40-talen var hon en känd och diskuterad författare, men med tiden har henneThe aim of this thesis is to present and discuss the author Gertrud Lilja with a special focus on her relationship to modernity from a feminist perspective. In the 1920s Lilja was regarded as an interesting and promising author. Ten years later she was seen as a conservative and popular author who wrote mainly for women. As this is the first published thesis that discusses Gertrud Lilja it focuses
Wood is a hygroscopic material; always striving to reach equilibrium with the surrounding air, and consequently the moisture content is different in different climate conditions. The strength of wood is directly dependent on the moisture content, lower moisture content leads to increasing strength. Generally, state moisture equilibrium is seldom obtained because the moisture transport in wood is v
Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie
The regional sensitivity of different vascular beds to i.v. CGRP was investigated in the albino rabbit by using the microsphere method. Experiments were performed without pre-treatment on both conscious and pentobarbital-anaesthetized animals. In addition, in one series on conscious animals, rabbits were pre-treated with indomethacin in order to reduce the formation of prostaglandins. In another s
Abstract in Uncoded languages Praegune kaitsejalatsite testimise standard (EN 344) kontrollib soojapidavuslikke omadusi vaid jalatsi ühes punktis, mõõtes temperatuuri muutust. Meetod, mis kasutab termilist jala mudelit, võimaldab mõõta jalatsi soojaisolatsiooni üheaegselt erinevates piirkondades ning ühtlasi ka jalatsi kui terviku soojaisolatsiooni. Selle uurimuse käigus arendati termilise jala mePresent standard on safety footwear (EN 344) checks the insulation only at one point in the shoes by means of measuring the temperature change. A method that uses thermal foot model allows to measure footwear insulation simultaneously at various locations and for whole footwear as well. In the present work the method of heated foot model was developed further. It is possible to simulate sweating a
Popular Abstract in Swedish ”Vi kommo överens om att möten innehålla alla livets möjligheter, och att en människa som levat mycket vet mycket om möten om hon alls vet någonting.” Så uttalar den kvinnliga huvudpersonen i Mannen vid min sida (1933) sin övertygelse efter mötet med älskaren. Denna avhandling fokuserar mötet i Elin Wägners trettiotalsromaner. Genom att analysera detta vill avhandlingsfThe aim of this present thesis is to present the Utopian scheme in Elin Wägner’s novels of the nineteen-thirties: Dialogen fortsätter (1932) (“The Dialogue Continues”), Mannen vid min sida (1933) (“The Man by my Side”), Genomskådad (1937) (“Unmasked”) and Hemlighetsfull (1938) (“Mysterious”). With her authorship Wägner was aiming for a new social order, a radical change, polväxling (a shift of pol
Mycorrhizal symbioses are formed between plant root systems and compatible fungal hyphae that results in a complex mixed structure. They are found in all ecosystems and with the majority of land plants such as forest trees or crops that are of commercial interest. Mutual exchange of nutrients between the two symbionts is central to the successful functioning of the symbioses. In order to understan
Popular Abstract in Swedish Arcanobacterium haemolyticum (A. haemolyticum) beskrevs för första gången under namnet Corynebacterim haemolyticum av MacLean och medarbetare 1946. Bakterien odlades fram från svalget hos patienter med halsont och från sår. Patienterna bestod av amerikanska soldater och infödda öbor i Stilla havet. Från olika delar av världen har senare beskrivits halsont och utslag hosIn an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial and e
Popular Abstract in Swedish Ekokardiografisk undersökning av hjärtat utvecklades i Lund i början av 1950 talet av kardiologen Inge Edler tillsammans med fysikern Helmuth Hertz och har under de första 30 åren huvudsakligen utförts via bröstkorgsväggen så kallat transthorakalt ultraljud. Under 1980 talet utvecklades tekniken och man fick instrument som via matstrupen kunde utföra en ekokardiografiskThe subject of this thesis is the clinical use of transesophageal echocardiography (TEE) in patients with stroke or atrial fibrillation. Subjects were examined with echocardiography and sonography of the carotid artery. A control group of randomly selected volunteers without cerebrovascular disease was compared to patients with ischemic stroke. Cardiac pathology was classified as minor potential e
Objective: To evaluate efficacy and cost-effectiveness of budesonide/formoterol (Symbicort*) maintenance (one dose once or twice daily) plus additional doses as needed (Symbicort Maintenance And Reliever Therapy, SMART) compared with a higher fixed dose of budesonide/ formoterol with formoterol as needed in patients with persistent asthma. Study design and methods: 6-month, open, randomised study
Inhaled corticosteroid (ICS) therapy is central to the long-term management of asthma and is extensively used in the management of chronic obstructive pulmonary disease (COPD). While administration via inhalation limits systemic exposure compared with oral or injected corticosteroids and, therefore, the risk of systemic corticosteroid-related adverse effects, concerns over the long-term safety of
BACKGROUND AND AIMS: The optimal position for pH electrode placement in the diagnosis of gastroesophageal reflux disease (GERD) is unknown. The aim of this study was to evaluate the discriminatory power of targeted pH recording immediately above the squamocolumnar junction (SCJ) and to compare the results with those obtained by simultaneous recording at the conventional level for pH monitoring. SU
Cerebral accumulation of amyloid-β is thought to be the starting mechanism in Alzheimer's disease. Amyloid-β can be detected by analysis of cerebrospinal fluid amyloid-β42 or amyloid positron emission tomography, but it is unknown if any of the methods can identify an abnormal amyloid accumulation prior to the other. Our aim was to determine whether cerebrospinal fluid amyloid-β42 change before am
Introduction: To investigate the incidence of neonatal early-onset group B streptococcal (GBS) infection in Sweden after promulgation of guidelines (2008) for risk factor-based intrapartum antibiotic prophylaxis, and evaluate the presence of risk factors and obstetric management in mothers. Material and methods: National registers were searched for infants with early-onset GBS infection during 200
Purposes: It has earlier been suggested that dietary supplementation with N-3 Polyunsaturated Fatty Acids (n-3 PUFAs) could have beneficial effects on cardio- vascular system patients with type 1 diabetes mellitus (DM1). Whether the benefit also extends to coronary circulation has not been yet investigated.Methods: In a double-blind placebo controlled cross-over study, 33 children with DM1 duratio
