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
Även om matchfixning och uppgjorda matcher har blivit ett allt mer omdiskuterat ämne det senaste åren saknas det i stort sett kunskap om hur läget är i Sverige. Det finns några enstaka forskningsrapporter och två hovrättsavgörande. Avsikten med uppsatsen har varit att undersöka vilka legala möjligheter det finns idag för att beivra matchfixning och hur den föreslagna spelfuskbestämmelsen i SOU 20Even if match fixing and manipulated matches have been a widely discussed topic the last few years, we still lack any deeper knowledge about the situation in Sweden apart from a few research reports and two rulings from the Court of Appeal. My intention with this bachelor thesis have been to examine which possibilities we have today to prosecute match fixing and how the proposed offence of cheati
In order to identify cellular factors that regulate human papillomavirus type 16 (HPV16) gene expression, cervical cancer cells permissive for HPV16 late gene expression were identified and characterized. These cells either contained a novel spliced variant of the L1 mRNAs that bypassed the suppressed HPV16 late, 5'-splice site SD3632, produced elevated levels of RNA-binding proteins SRSF1 (ASF/SF
Barley husks, rye bran, and a fiber residue from oat milk production were processed by heat pretreatment, various separation steps, and treatment with an endoxylanase in order to improve the prebiotic potential of these cereal byproducts. Metabolic functions were intended to improve along with improved microbial activity. The products obtained were included in a high-fat mouse diet so that all die
Hemicelluloses, which are abundant in nature and have potential use in a wide variety of applications, may make an important contribution in helping relieve society of its dependence on petrochemicals. However, cost-efficient methods for the isolation of hemicelluloses are required. This article presents an economic evaluation of a full-scale process to isolate hemicelluloses from process water fr
A processing method is developed to characterize contacts for vertical nanowire structures. The process is based around optical lithography and an organic spacer material in order to facilitate an easily repeatable processing flow. Substrates with MOVPE grown GaSb nanowires are processed into sets of resistor devices. Variation in resistance of the devices is achieved by adding contacts at differen
The EES, Lisbon and Europe 2020 are the most relevant soft law strategies promoting the improvement of work-family reconciliation-related policies in the EU Member States. In this study, the cases of the German Elterngeld reforms are applied to scrutinise the influences of these three strategies on domestic policy-making. Thus, this research work is based on the theoretical framework of soft Europ
This master's thesis is about the implementation and evaluation of a small object-oriented automation system. By using a realtime Java VM from Jamaica, a sheet feeding magazine from the machine Tetra Aptiva Aseptic has been controlled. The expectations included to achieve more structured and safer programming, better documentation through UML and to separate application developers from develop
The aim of this qualitative study was to investigate and shed light on how care workers perceive their care work and the dilemmas they encounter in the work of adults diagnosed with severe intellectual disabilities. I conducted six semi-structured interviews with care workers working with the study target audience. For my analysis, I have applied the theoretical perspectives ethics of response, pr
Insects have been recommended by the FAO as a sustainable food alternative to meat. Despite their nutritional quality and sustainability, most Western countries still see insects as belonging far away from the dinner table. Although still a niche market, Denmark has been at the forefront of innovation and adoption of edible insects. I used integral theory to map out the structural, cultural and pe
The present Comite´ Europe´en de Normalisation (CEN) and International Organization for Standardization (ISO) standards for safety, protective and occupational footwear EN ISO 20344–20347 classify footwear as cold protective by a pass/fail test where the limits are set for an allowed 10 °C temperature drop inside the footwear during 30 min at a temperature gradient of ~40 °C. It is questionable if
The impact echo (IE) method is widely used in non-destructive testing of concrete plate like structures but has proved difficult to apply on asphalt pavements. Observed low IE resonance amplitudes on asphalt have been attributed to larger material damping but the present study shows that it may also be an effect from a larger Poisson's ratio. The IE frequency corresponds to the stationary resonanc
The old beech forest (250–300 yr) at Bjurkärr (core area 30 ha) in the province of Småland, S Sweden, was surveyed for epiphytic lichens of conservation concern in 1993–94. Several rare red-listed lichens were recorded, many with large populations. In 2011 the most endangered lichens were resurveyed due to the incorporation of Bjurkärr in the forthcoming national park of Lake Åsnen. Most species o
BACKGROUND: Hypothermia may be accidental or therapeutic. Therapeutic hypothermia is increasingly used as treatment for various conditions, e.g., neuroprotection after cardiac arrest. Hypothermia leads to an impairment of the coagulation system, but the degree of impairment has been difficult to determine. Most studies have been performed on plasma instead of whole blood. We therefore evaluated wh
Using Drosophila melanogaster as a study organism, we tried to find differences in male and female attractiveness due to female-limited X-chromosome evolution (FLX). In the first part of the experiment, we tested the male attractiveness (measured as female preference) of the FLX-populations and as a control group we used the LHm-population. (LHm comes from a large laboratory-adapted population co
