Besökarna kring Ivösjön har på senare år märkt av en förändring av vegetationen kring och i Ivösjön och därigenom en förändring av strandlinjens utformning. Sjön tycks allt mer växa igen av vass och flytbladsväxter, vilket tyder på en eutrofieringsprocess. I den här rapporten jämförs flygbilder från olika tidpunkter under en 70-års period fram till och med idag för att se om sjön verkligen har vuxThe visitors around Ivösjön have recently discovered observed a change in the vegetation around and into the lake and consequently a change in the formation of the shoreline. The lake appears to have been increasingly filled up by reed and floating leaf plants which points to an eutrophication process. In this report aerial photographs are compared from a period of 70 years up until today to disco

Alzheimer’s disease (AD) is clinically characterised by an insidious onset with progressive symptoms of memory impairment, dysphasia, dyspraxia, dygnosia and visuospatial difficulties. Degeneration of neurons in specific regions of the brain, formation of senile plaques and neurofibrillary changes are some of the neuropathological features of the disease. As a result of the degenerating process a

This thesis sets out to examine which tax consequences might arise when moving a closely held company abroad, according to Internal Law, European Community Law (EC Law) and Double Taxation Treaties. To be able to illustrate the tax consequences I have chosen to look at a specific case where a shareholder undertakes a sale of shares of his Swedish company to a foreign company also owned by him. The

Pappers- och pappersmassaindustrin har ökat markant under de senaste årtiondena. På grund av att samhället har blivit mer miljömedvetet har återvinning av papper blivit en allt viktigare del inom industrin. Återvunna pappersfiber är dock av lägre kvalité än nygjorda fibrer. Syftet med denna rapport är att analysera möjligheterna att använda ett enzym av typen lackas för att modifiera interaktionenThe pulp and paper industry have been a growing market during the last decades. Due to higher environmental concerns among people, the recycling of papers has become an even more important part of the industry. Recycled paper fibers however are of lower quality than virgin fibers. This report aims to analyze the possibility to use a laccase enzyme to modify the interaction between lignin and recyc

The drug discovery and development process has changed dramatically during the last decades and the growth of more efficient techniques as high throughput screening combined with combinatorial synthesis using amino acids and carboxylic acids on solid support makes it possible to investigate the affinity of molecules towards a biological target. Fragment based drug discovery (FBDD) has been impleme

Populärvetenskaplig sammanfattning Klimatet har sedan den industriella revolutionen förändrats globalt och kommer att förändras ytterligare i framtiden, på grund av människans utsläpp av växthusgaser. Enligt vetenskapliga beräkningar kommer klimatet att bli varmare, vilket i sin tur leder till att den globala havsnivån kommer att stiga. Hela världen kommer drabbas, även Sverige. Därför krävs det aSince the industrial revolution the global climate has changed and will change further in the future. According to scientific estimations the climate will get warmer, which will rise the global sea level. The whole world will be affected, also Sweden. It is therefore necessary to adapt society for the estimated climate change to reduce negative effects. In May 2012 a change in the Swedish law of

The aim of this study was to derive dietary patterns associated with cardio-metabolic traits and to examine whether these predict prospective changes in these traits and incidence of the metabolic syndrome (iMetS). Subjects from the Malmö Diet and Cancer Study cardiovascular cohort without cardio-metabolic disease and related drug treatments at baseline (n 4071; aged 45-67 years, 40 % men) were in

Sprifermin, recombinant human fibroblast growth factor 18 (rhFGF18), induces cartilage regeneration in knees of patients with osteoarthritis (OA). We hypothesized that a temporal multiphasic process of extracellular matrix (ECM) degradation and formation underlie this effect. We aimed to characterize the temporal ECM remodeling of human knee OA articular cartilage in response to sprifermin treatme

A protective coating is often used on the cladding of wooden facades to limit the absorption of moisture. Low wood moisture content (MC) is essential to obtain satisfactory durability performance. Wood density is known to influence the water sorption and crack formation of uncoated wood. However, the effect of density on the aforementioned behaviors of coated spruce is not yet fully understood. Si

Ciliary neurotrophic factor (CNTF) promotes photoreceptor survival but also suppresses electroretinogram (ERG) responses. This has caused concerns about whether CNTF is detrimental to the function of photoreceptors because it is considered to be a potential treatment for retinal degenerative disorders. Here we report that the suppression of ERG responses is attributable to negative regulation of t

Background: Patients treated for Pediatric Brain Tumors (PBTs) often experience a decline/stagnation in their cognitive functioning.Anumber of potential risk factors for cognitive decline have been identified including gender (female), young age-at-diagnosis, higher baseline IQ, hydrocephalus at diagnosis, treatment with Whole Brain Radiation Therapy (WBRT), and larger radiation field and/or dose.

BACKGROUND: Parkinson's disease (PD) can cause impulsivity with premature responses, but there are several potential mechanisms. We proposed a distinction between poor decision-making and the distortion of temporal perception. Both effects may be present and interact, but with different clinical and pharmacological correlates.OBJECTIVES: This study assessed premature responding during time percept

Charge transfer interactions between C60 and the metal surfaces of Ag(111), Cu(111), Au(111) and Pt(111) have been studied using synchrotron-based photoemission, resonant photoemission and X-ray absorption spectroscopies. By placing the X-ray absorption and valence band spectra on a common binding energy scale, the energetic overlap of the unoccupied molecular orbitals with the density of states o

Aims: Patterns of species richness, such as the remarkable biodiversity of tropical regions, have been documented and studied for centuries. However, their underlying evolutionary and ecological causes are still incompletely understood. A commonly stated paradigm in the literature is that high richness in some habitats is directly caused by one of three competing explanations: (1) greater time-for

We have earlier demonstrated that a Status Epilepticus (SE) during CNS development has long-lasting effects on cholinergic neurotransmission, detectable in vitro and in vivo. In this work, we aimed to localize changes in temporal (T) vs septal (S) hippocampus and to correlate adult CA3 interictal epileptiform discharge (IED) frequency changes to those of Ripples (R) and Fast Ripples (FR) of the Hi

Aims. The central region of a circumstellar disk is difficult to resolve in global numerical simulations of collapsing cloud cores, but its effect on the evolution of the entire disk can be significant. Methods. We used numerical hydrodynamics simulations to model the long-term evolution of self-gravitating and viscous circumstellar disks in the thin-disk limit. Simulations start from the gravitat

Atherosclerosis and its clinical consequences are the leading cause of death in the western hemisphere. While many studies throughout the last decades have aimed at understanding the disease, the clinical markers in use today still fail to accurately predict the risks. The role of the current main clinical indicator, low density lipoprotein (LDL), in depositing fat to the vessel wall is believed t
