Agricultural policies have always had a tendency to be controversial. In many cases they generate major transfers of welfare between different groups of people, and hence are favoured by some and criticised by others. They also frequently cause trouble at the international level as domestic programmes interfere with trade flows and affect the wellbeing of people in other parts of the world. In add

Popular Abstract in Swedish I Sverige och Norden har elproduktion traditionellt skett med huvudsakligen vattenkraft och kärnkraft. Detta håller dock på att förändras i takt med en allt större vindkraftsutbyggnad. Vindkraften skiljer sig i vissa avseenden från de traditionella produktionsslagen, ett av dessa är hur anslutningen till elnätet är utformad. Detta innebär att vindkraften, sedd från näteTraditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. This thesis deals with the impact on rate of change of frequency

This work has been made as a thesis for a BSc degree in Fire Protection Engineering at Lund University. The work has been supported and funded by ESS AB, European Spallation Source, in Lund. ESS AB is a publicly held company, owned by Sweden and Denmark as host countries. These host countries, together with at least 17 other European countries, will build and establish a multidisciplinary research

Diabetes mellitus is a disease characterized by increased blood glucose levels. For overt type 2 diabetes to develop, both insulin action and insulin secretion must be perturbed. In the work presented in this thesis, two models were analyzed: hormone-sensitive lipase (HSL) null mice and a pancreatic clonal β-cell line to study the mechanisms underlying insulin resistance and insulin secretion pert

Popular Abstract in Swedish Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is

We have investigated the potential impact on organic aerosol formation from biotic stress-induced emissions (SIE) of organic molecules from forests in Europe (north of lat. 45° N). Emission estimates for sesquiterpenes (SQT), methyl salicylate (MeSA) and unsaturated C17 compounds, due to different stressors, are based on experiments in the Jülich Plant Atmosphere Chamber (JPAC), combined with esti

Aims. Until recently, most high-resolution spectroscopic studies of the Galactic thin and thick discs were mostly confined to objects in the solar vicinity. Here we aim at enlarging the volume in which individual chemical abundances are used to characterise the thin and thick discs, using the first internal data release of the Gaia-ESO survey (GES iDR1). Methods. We used the spectra of around 2000

Differences between ages, sexes and populations in the timing of migration at Falsterbo, Sweden and in the choice of wintering site among raptors in Scania were investigated. Competition and dominance is the best primary explanation to the results. In most cases the more competitive adults winter north of juveniles and the larger females north of males. Moult strategy is probably one of the most i

This thesis addresses the impact of glaucoma on the patients’ vision from both a measurement based and a functionally based perspective. The risk of visual disability is probably the most important question for a newly diagnosed glaucoma patient and maintaining vision-related quality of life (VRQOL) has become the ultimate goal of glaucoma treatment. The objectives of the present thesis were to de

Context Small single-center studies have shown that cerebrospinal fluid (CSF) biomarkers may be useful to identify incipient Alzheimer disease (AD) in patients with mild cognitive impairment (MCI), but large-scale multicenter studies have not been conducted. Objective To determine the diagnostic accuracy of CSF beta-amyloid(1-42) (A beta 42), total tau protein (T-tau), and tau phosphorylated at po

Popular Abstract in Swedish I december 1990 antog riksdagen i Sverige ett miljötillägg i skollagens s k portalparagraf: "Var och en som verkar inom skolan skall främja? respekt för vår gemensamma miljö." Alltså: Alla som verkar i skolan ska nu ta sig an den nya miljötematiken i samhället. Strax därefter tillsatte regeringen en ny läroplanskommitté med ett tydligt miljöuppdrag. I juni 1992, vid FNThis thesis explores the various influence processes that take place in connection with the dawn of a new theme - the environment - in today's society. Society has declared that schools, a place designed for the intentional influence of children and youths, shall utilise the new environmental theme in its practice. It focuses on the initiation process of the environmental theme in schools from the

Mixed acid phospholipids are valuable compounds, which are used mainly in membrane- and lipoprotein research and in liposome technology. The chemical synthesis of these special lipids is rather difficult and involves both toxic chemicals and harsh reaction conditions, which makes the products less attractive for medical and biological applications. Enzymes in contrast catalyze chemical reactions u

Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available. This thesis focuses on dehydration methods that take into account the fragile and complex cellular tiss

Denna avhandling behandlar en mängd mikrostrukturella och molekylära lämningar som påträffats i ett antal fossil. Resultaten presenteras i sex vetenskapliga artiklar med det gemensamma syftet att grundligt studera dessa lämningar med hjälp av såväl nya som vedertagna analysmetoder. Avhandlingens huvudsakliga frågeställningar är dels vad denna typ av fossila spår kan säga om de studerade djurens biThis thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods. The main questions asked are: What can we learn about the biology, ecology and

OBJECTIVE: To compare consultations carried out via video with those performed in person for patients with painful, hard-to-heal ulcers, with a focus on ulcer pain and pain treatment. A further aim was to investigate predictors for pain and pain treatment.METHOD: This was a register-based, quasi-experimental study based on data from the Swedish Registry of Ulcer Treatment (RUT). A total of 100 pat

Today, there are increased expectations that welfare employees should conduct service innovative improvements that enable more effective ways to meet the needs of children.In this study we use the definition of ‘service innovation’ as a way to change the value-adding process of the user so that it becomes better for the end-user than it was before, such as easier to handle things or situations. In

Objective: To explore whether magnetic resonance imaging (MRI) features suggestive of knee osteoarthritis (OA) are associated with presence of knee pain in possible early-stage OA development. Methods: We included 294 participants from the Osteoarthritis Initiative (mean ± SD age 50 ± 3 years; 50% women) with baseline Kellgren/Lawrence grade of 0 in both knees, all of whom had received knee MRIs a

IMPORTANCE Treatment trials require sound knowledge on the natural course of disease. OBJECTIVE To assess clinical features, genetic findings, and genotype-phenotype correlations in patients with retinitis pigmentosa (RP) associated with biallelic sequence variations in the PDE6A gene in preparation for a gene supplementation trial. DESIGN, SETTING, AND PARTICIPANTS This prospective, longitudinal,

Nowadays, strengthening of reinforced concrete structures with a new class of sustainable materials is the possible solution to retrofit the aged deteriorated structures. It is difficult to predict the capacity of the strengthened (FRP/FRCM) reinforced concrete elements without considering the bond strength. Therefore, the concrete substrate to Fibre-Reinforced Cementitious Matrix (FRCM) bond is a

Monoclinic β-Ga2O3 films grown on c-plane sapphire have been shown to exhibit six (2¯01)-oriented domains, which are equally spaced by rotation around the surface normal and equally sized by volume that render the film optical response effectively uniaxial. We derive and discuss an optical model suitable for ellipsometry data analysis of such films. We model mid- and far-infrared ellipsometry data
