Popular Abstract in Swedish Regnvatteninsamling genom översvämningskontroll för artificiell grundvatteninjektering är en traditionellt använd metod i arida och semiarida Iran. Metoden har använts under flera tusen år för att öka andelen vatten som kan användas till jordbruksproduktion. Under de senaste 100 åren har emellertid mycket av den traditionella kunskapen om dessa metoder fallit i glömska Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. Water harvesting techniques have been traditional solutions to water scarcity problems in the arid and semiarid Middle East for thousands of years. Th

Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. As a consequence, numerous research programs concerning polymerization processes (e.g. emulsion po

Popular Abstract in Swedish Syftet med studierna som presenteras i denna avhandling har varit att undersöka om fordonsetanol kan framställas på ett lönsamt och energieffektivt sätt från restprodukter från jord- och skogsbruk enligt svenska förhållanden. Mycket av den forskning som rör andra-generationens etanolproduktion går ut på att förfina och förbättra de separata delstegen i framställningsproSweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. A large amount of research has been devoted toward the development of sustainable

Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the

Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. Furthermore, it should be recycled because of environmental and economical concerns. Corrugated board has all of these featu

A mathematical model is presented for photosynthetic carbohydrate formation in C3 plants under conditions of light and carbon dioxide saturation. The model considers reactions of the Calvin cycle with triose phosphate export and starch production as main output processes, and treats concentrations of NADPH, NAD+, CO2, and H+ as fixed parameters of the system. Using equilibrium approximations for a

Avhandlingen har titeln ”Konsten att upprätthålla löneskillnader mellan kvinnor och män” och är en rättssociologisk studie av vad som stått i vägen för likalöneprincipen, när internationella konventioner och EU-rätten medfört krav på förändringar av kollektivavtal och lagstiftning. Avhandlingens syfte har varit att undersöka och förstå hur löneskillnader mellan kvinnor och män skapas och återskapaThis dissertation, entitled “The Art of Preserving the Gender Pay Gap,” is a study in the sociology of law. It examines the obstructions to the principle of equal pay that persist in the face of international conventions and EU legislation that have mandated changes to legislation and collective bargaining agreements. The dissertation seeks to investigate and explain how the pay gap between women

Forests are invaluable terrestrial ecosystems with considerable economic, ecological, and environmental benefits. Bark beetles have been recognized as one of the major causes of forest disturbance, and climate change can exacerbate their impact, leading to more tree mortality. Early detection of bark beetle attacks is vital to reduce forest loss and devastating consequences. This study examines th

Aims/hypothesis: Monogenic forms of diabetes (MODY, neonatal diabetes mellitus and syndromic forms) are rare, and affected individuals may be misclassified and treated suboptimally. The prevalence of type 1 diabetes is high in Finnish children but systematic screening for monogenic diabetes has not been conducted. We assessed the prevalence and clinical manifestations of monogenic diabetes in chil

As a result of climate change warmer temperatures are projected through the 21st century and are already increasing above modelled predictions. Apart from increases in the mean, warm/hot temperature extremes are expected to become more prevalent in the future, along with an increase in the frequency of droughts. It is crucial to better understand the response of terrestrial ecosystems to such temp

The PI3K/mTOR pathway is the second most frequently deregulated pathway in a majority of cancers such as breast cancer, lung cancer, and melanomas as well as leukemia. Mutations in the genes coding for receptor tyrosine kinases (RTKs) and G-protein-coupled receptors (GPCRs) are quite common in all forms of acute leukemia. This can be a major cause of deregulation of the PI3K-mTOR pathway. To under

Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maxim

Background. Multiple studies have demonstrated that partitioning of molecular datasets is important in model-based phylogenetic analyses. Commonly, partitioning is done a priori based on some known properties of sequence evolution, e.g. differences in rate of evolution among codon positions of a protein-coding gene. Here we propose a new method for data partitioning based on relative evolutionary

Background:In early breast cancer, five histopathological biomarkers are part of current clinical routines and used for determining prognosis and treatment: estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (ERBB2/HER2), Ki67, and Nottingham histological grade (NHG). We aimed to develop classifiers for these biomarkers based on tumor mRNA-sequencing (RNA

Glutathione (GSH) is an endogenous antioxidant implicated in numerous biological processes, including those associated with multiple sclerosis, aging, and cancer. Spectral editing techniques have greatly facilitated the acquisition of glutathione signal in living humans via proton magnetic resonance spectroscopy, but signal quantification at 7 Tesla is still hampered by uncertainty about the gluta

Det här avhandlingsprojektet handlar om självmedvetande och hur det förhåller sig till medvetande i stort. Mer specifikt handlar det om jagupplevelse, känslan av att vara ett jag, och om denna känsla med nödvändighet finns med i alla våra upplevelser eller inte. Vad betyder det då att ha en känsla av att vara ett jag? Det kan betyda flera saker, exempelvis känslan av att vara samma person över tidThe present dissertation project concerns the relationship between self and consciousness. Specifically, it concerns the phenomenal sense of self and if this is a necessary component of all experience or not. What is it to have a sense of self? This can refer to several things, such as the sense of being a continuous person through time, the sense of having a body, the sense of being in control of

Plasma phosphorylated tau (p-tau) biomarkers open unprecedented opportunities for identifying carriers of Alzheimer's disease pathophysiology in early disease stages using minimally invasive techniques. Plasma p-tau biomarkers are believed to reflect tau phosphorylation and secretion. However, it remains unclear to what extent the magnitude of plasma p-tau abnormalities reflects neuronal network d

Säkerhetsläget i Europa har förändrats drastiskt under de senaste åren, med de två största förändringarna i Rysslands invasion av Ukraina, och NATO:s expandering med Sverige och Finland som nya medlemsstater. Den ökade militariseringen i Europa har också resulterat i att en gammal fråga nu igen dykt upp i den allmänna debatten, nämligen frågan om Åland borde remili-tariseras i syfte att säkra ÖsteThe security in Europe has changed dramatically during recent years, with the two most significant changes being Russia’s invasion of Ukraine, and NATO:s expansion with Sweden and Finland as new member states. The increasing militarization in Europe has also brought back an old question into the public debate, namely if the Åland islands should be re-militarized with the purpose of securing the Ba

This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. The research draws on data collected through interviews and observations of older people in relation to three robots. The results show that older people’s domest

How mice avoid diseases, a measure of divergence The response we have to diseases vary from person to person. In much the same way diseases affect and are battled in many different ways depending on the species. This happens due to differences in their immune system. So, what causes these differences? Well, they are mostly caused by differences in the DNA, the molecule which has the code for ever
