This thesis deals with the properties of wheat storage proteins at interfaces. These proteins are the main constituents of gluten and are recognised for their importance in breadmaking. The components studied were gliadin fractions (a-gliadins, b-gliadins, g-gliadins and w-gliadins), the high-molecular-weight glutenin subunit 1Dx5, and a 58 kDa peptide derived from the central repetitive domain of
This study is aimed at investigating and describing the different procedures of foreign language learners of Italian when they infer the meaning of unknown words in a written authentic text. Vocabulary is a crucial component in the learning process of a foreign language and many studies show that lexical inferencing is one of the most important strategies when foreign language learners encounter u
Popular Abstract in Swedish Polymerelektrolytbränslecellen utmärker sig som en framtida effektiv och miljövänlig kraftkälla för bland annat fordon. Den bakomliggande teknologin är dock komplex och grundar sig till stor del på material och komponenter som kräver ytterliggare utveckling. En av de största hindren för bränslecellsteknologins utveckling är kravet på nya, långlivade och billiga polymermThe proton exchange membrane fuel cell (PEMFC) is currently emerging as an efficient and environmentally friendly power source. The technology is very complex and relies ultimately on materials and components which need further development. One of the major hurdles for advancing the PEMFC technology is currently the demand for new durable low-cost polymeric membranes that will allow fuel cell oper
Background: Daycare infants have more infectious episodes, see a physician more often, and are prescribed antibiotics more often than home care infants. Aim: To compare physician consultations and antibiotic prescription in daycare children and home care children taking number of symptom days, sociodemographic factors, concern about infectious illness and antibiotic knowledge into account. Methods
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
A study on the catalytic behaviour of a copper and a platinum titania based monolithic catalyst in the reduction of nitrogen oxides with hydrocarbons in real diesel conditions was carried out. A Volvo TD 7.31 engine was used as gas source, and diesel fuel was the reductant. In these conditions, both catalysts were active in the reduction reaction. The influence of various operating parameters on t
Hemicellulolytic obligate anaerobes capable of converting a range of agricultural substrates and monomeric sugars of hemicellulose to solvents and acids were isolated from cow rumen fluid. The strains were identified as 5 strains of C. beijerinckii (3 different genotypes), 3 strains of C. acetobutylicum (2 different genotypes), 1 strain of C. butyricum and 3 strains of C. bifermentans (2 different
There currently exists legislation within Europe banning the use of dyestuffs based on certain carcinogenic amine compounds. Currently a test method exists that is used by the industry (CEN ISO TS 17234 based on DIN 53316). This is able to detect twenty of the compounds listed by the legislation but is not validated for the recently added 2-methoxyaniline and is unsuitable for analysis of -Aminoaz
Romania has for a long time been lacking good palaeoenvironmental records, particularly for the Late Quaternary. A chronological framework had been nearly absent and the vegetation development had been reconstructed entirely from pollen data. Data sets from this part of Europe are important for assessing the spatial variability of past vegetation and climatic changes and to reconstruct tree migrat
Objective. To assess the accuracy and reproducibility of robot-assisted laparoscopic abdominal fertility sparing radical trachelectomy in women with early stage cervical cancer. Methods. Relevant prospective clinical data from 13 consecutive women planned for robotic radical trachelectomy between 2007 and 2012 were compared with retrospective data from 12 consecutive women planned for vaginal radi
BACKGROUND: Children with cerebral palsy (CP) often walk with a slower speed and a higher energy cost. Their walking performance and choice of mobility method may vary in different environments. Independent mobility is important for activity and participation. QUESTIONS/PURPOSES: We described walking performance at different distances and environments in relation to gross motor function, CP subtyp
Background: Levosimendan has been proposed as an attractive alternative to adrenergic agents for the treatment of sepsis-induced heart failure and haemodynamic derangements. Its use in this setting is, however, still not well investigated. The aim of this study was to test the hypothesis that levosimendan is able to attenuate endotoxin-induced pulmonary hypertension and improve myocardial function
Epidemiological studies have shown an increased incidence of cancer among workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs). As the dermal route is considered important for exposure to PAHs in the workplace, the aim of this study was to develop and evaluate a tape-stripping technique for monitoring dermal exposure to pyrene and benzo(a)pyrene. The tape-stripping method was
To develop radioimmunoassays (RIAs) for rat trypsinogens 1 and 2 and to investigate the effect of nicotine exposure on concentration and production of pancreatic zymogens in the rat. METHODS: Male Sprague-Dawley rats were supplied with either normal or nicotine-containing (0.77 mM) water for 28 days and were then killed. Rabbit antibodies for the activation peptides of trypsinogens 1 and 2 were ob
The central complement inhibitor factor I (FI) degrades activated complement factors C4b and C3b in the presence of cofactors such as C4b-binding protein, factor H, complement receptor 1 and membrane cofactor protein. FI is a serine protease composed of two chains; the light chain comprises the serine protease domain, while the heavy chain contains several domains: the FI and membrane attack compl
OBJECTIVES: This study examined which individual and national factors affect condom use among adolescents. STUDY DESIGN: Multilevel analysis. METHODS: This study reviewed the data on bullying, alcohol use and condom use provided by 18 European countries and subnational entities in the Health Behaviour in School-Aged Children survey. Another eight contextual variables were also analysed. Three mult
To study and compare associations between life satisfaction and standard of living, health, and coping behaviour in older single-living women in two countries with different political, economical and cultural situations: Latvia and Sweden. Cross sectional data included 260 Latvian and 288 Swedish women, aged 75-84 and 80-89, from the ENABLE-AGE Survey Study. Life satisfaction was assessed by the q
This thesis treats two separate but connected themes. This affiliation originates in optimization being the common choice of method for solving most of the occurring challenges. The first theme of the thesis is image segmentation. This is usually defined as the task of distinguishing objects from background in unseen images. This visual grouping process is typically based on low-level cues suc
