Ultrafiltration can be used to concentrate arabinoxylan isolated from wheat bran. Prefiltration with diatomaceous earth and air sparging during ultrafiltration of the alkaline hemicellulose solution were both found to increase the flux, while nitrogen sparging had no effect. The flux of the untreated solution was 51 L/m2 h, while the flux after prefiltration of the solution with diatomaceous earth
Research on winter energy management in small vertebrates has focused on the regulation of body mass (BM) within a framework of starvation-predation trade-off. Winter-acclimatized birds exhibit a seasonal increase in both BM and basal metabolic rate (BMR), although the patterns of co-variation between the two traits remain unknown. We studied this co-variation in three different species of wild ti
Elevated concentrations of arsenic in drinking water are common worldwide, however, little is known about the presence of other potentially toxic elements. We analyzed 31 different elements in drinking water collected in San Antonio de los Cobres and five surrounding Andean villages in Argentina, and in urine of the inhabitants, using ICP-MS. Besides confirmation of elevated arsenic concentrations
The use of mobility devices, such as walking sticks and rollators, increases during the ageing process. Our aim was to explore how very old single-living Swedish women experience the use of mobility devices over time, in relation to everyday occupation. A multiple case study strategy involving quantitative and qualitative data was used. The findings indicate that the use of mobility devices, rolla
The aim was to explore health in relation to the home as experienced by very old, single-living Swedish people. Applying a grounded theory approach, 40 men and women aged 80-89 were interviewed in their own homes. Data analysis revealed the main theme, "The home is the hub of health", comprising two categories, "The home as support for health", and "Having an inner driving force to maintain health
The food system today is faced with enormous challenges, leading to negative externalities which influence all the layers of sustainable development. In this scenario, the transition from a linear to a Circular Economy for the global food system, but also for the entire economy, has been proposed as a solution towards reducing environmental pressure from economic growth. The aim of this thesis is
In Sweden, the 10th most common occupation is professional cleaning. Cleaning workers are exposed to many risk factors including high physical workload and the development of new-onset asthma and other types of respiratory symptoms. This master thesis has been a part of a research project at the division of Ergonomics and Aerosol Technology (EAT), Lund University, in which the health aspect of cle
We are emerging into the IoT (Internet of Things) era as the IoT market is quickly increasing, giving us connected devices everywhere, from personal accessories to smart homes and even whole city infrastructures. The manufacturing companies need to stay competitive in this rapidly evolving market, so they need to minimize the price and optimize the Time to Market (TTM). When new versions of a prod
Urban environments are rapidly growing worldwide with severe consequences to animals and plants residing in our cities. Some of the most well-studied urban wildlife is passerine birds, where a wide array of effects have been documented; smaller clutches, earlier breeding, shorter telomeres and oxidative stress are just some costs among numerous others. Yet, few studies have so far investigated the

Due to climate change, emissions of greenhouse gases must be reduced rapidly and natural resources must be used more sustainably. The public sector should lead the way to a more sustainable society and healthcare has been identified as an area that contributes to large emissions. The purpose of this study was to identify measures that can be taken to reduce the climate impact of the retirement ho
I ett allt mer individbaserat samhälle, med ett skifte från normer när det gäller levnadssätt till allas unika livsval, ser vi ett ökat behov av boende för olika typer av konstellationer. Kärnfamiljen är inte lika självklar längre, ensamhushållen är fler och separationer är vanligt. Människor kan välja att bli förälder på egen hand och tvåsamhet som en självklarhet ifrågasätts helt och hållet. Vi In our individualized society, with a shift from strict norms on how we live our lives to everyone’s own unique lifestyle, we see a growing need for diversified housing for different types of constellations. The nuclear family is not a certainty anymore, the number of single residencies have increased and separations are common. People can choose to become a parent on their own and twosome relatio
Recently, several regions in southern Sweden suffered extremely low groundwater levels following a long-term infrequency in rainfall. In response, irrigation was banned in many of the affected municipalities during 2016–2017, amongst which Mörbylånga municipality was one. Because nearly half of the nation’s drinking water is extracted from groundwater, protecting and managing this vital resource i
Reduced growth rates in saturated developed economies have put increasing pressure on multinational companies (MNCs) to expand to rapidly developing emerging markets and capitalize on their value potential. Yet, this value potential comes with several challenges which are very different from what firms experience in developed countries, especially with regards to the bottom of the pyramid. The Tra
Introduction We aimed to compare the proportions of patients with newly diagnosed psoriatic arthritis (PsA) and rheumatoid arthritis (RA) remaining on methotrexate (regardless of other disease-modifying antirheumatic drug (DMARD)-changes), and proportions not having started another DMARD (regardless of methotrexate discontinuation), within 2 years of starting methotrexate, as well as methotrexate
Exotic plants can compete well with native species because many invasive species are considered better nutrient users in both low- and high-resource environments. However, whether invasive plants can outperform native plants at all stages of invasion is not very clear. We investigated the nitrogen (N), phosphorus (P) and N:P homeostasis of an invasive Eupatorium adenophorum and a co-occurring nati
Introduction: Most centers treating patients with anorectal malformation (ARM) will screen for anomalies of the kidneys and urinary tract by using ultrasonography. There is no consensus on whether screening for vesico-ureteral reflux (VUR) should occur. To meet the diagnostic needs of ARM patients a method was developed to include a simultaneous VUR diagnosis and pre-reconstructive fistula work-up
