The aggregation of amyloid-β peptide (Aβ) into amyloid fibrils and plaques is one culprit to Alzheimer’s disease pathogenesis. Once a small concentration of amyloid fibrils has formed through primary nucleation, a fibril-catalysed secondary nucleation takes over, leading to a close to exponential growth. Here, we have investigated the effect of five (J46, I48, J44, I68 and J7) out of twelve previo

Milk is a complex liquid, which contains many different species, for example proteins, fat, minerals etc. It is the primary source of nutrition for young mammals before they are able to digest other types of food. The proteins can be divided into two groups: caseins and whey. Whey proteins are about 20 wt % of the total protein amount in milk, whereas the caseins corresponds 80 wt % of the total p

Malaria is one of the diseases that spread by insect vectors. The disease is carried to humans by female Anopheles mosquitoes. It is caused by the plasmodium types. The most prevalent and dangerous type of plasmodium is Plasmodium falciparum (Pf). The disease occurs in 104 countries and approximately 216 million new cases of malaria and around 655,000 deaths takes place every year. Many drugs have

Ensamstående mödrar känner oftare stress i vardagen än andra föräldrar. Vid ökad föräldrastress visar barnet ett mer utåtagerande beteende och anknytningen till föräldern försämras. Syftet med studien var att få kunskap om vilka faktorer som påverkade stressen hos ensamstående föräldrar och om hur de förhöll sig till dessa. Tolv intervjuer utfördes utifrån ett bekvämlighetsurval. De faktorer som p

The N-body problem has been studied for many centuries and is still of interest in contemporary science. A lot of effort has gone into solving this problem but it's unlikely that a general solution will be found with the mathematical tools we have today. We review some of the progress that has been made over the centuries in solving it. We take a look at the first integrals, existence of solut

Att utföra meningsfulla aktiviteter har visat vara viktigt för att uppnå god hälsa. Vad som gör en aktivitet meningsfull kan ses på många olika sätt och är individuellt. Fontänhuset är ett etablerat klubbhus för personer med psykiskt funktionshinder och studier har visat att detta klubbhus erbjuder meningsfulla aktiviteter. Den här studien ämnade undersöka vad som ger mening i aktivitet hos medlem

This thesis examines the diachronic semantic development in terms of metonymization and metaphorization for 30 nouns loaned into the Swedish language between the 13th and 20th centuries from a cognitive-semantic point of view. Through the framework of Lexical Meaning as Ontologies and Construals (LOC) combined with a study of the occurrence of metaphorization, metonymization, widening and narrowin

In recent years there has been significant research conducted into how predicted climate change scenarios could negatively impact wine grape quality across various regions in the world. This has highlighted the particularly vulnerable state of the wine industry to climate change, and the important role research in this area can play in identifying new knowledge and conceptual frameworks regarding

Abstrakt Barn med övervikt och fetma är ett folkhälsoproblem som barnhälsovården (BHV) har en unik möjlighet att förebygga. Materialet Grunda Sunda Vanor (GSV) kan användas av distrikts- och barnsjuksköterskan. GSV är nationella riktlinjer som ingår i Rikshandboken för barnhälsovård. Syftet med studien var att undersöka distrikts- och barnsjuksköterskans följsamhet till riktlinjerna i det preventi

Abstract The study of teachers and students’ perceptions of second language acquisition (SLA) and teaching began in earnest with Horwitz’s seminal research during the 1980s. Numerous studies into both teachers and learners’ belief systems have since then been conducted by researchers and educators (Bell, 2005; Borg & Burns, 2008; Brown, 2009; Davis, 2003; Horwitz, 1987, 1988; Lasagabaster &

Sedan hösten 2006 har lagstiftningsprocessen fått ett nytt inslag. Ett oreglerat och nästan okänt inslag, men ack så viktigt. När de fyra borgerliga partierna under åren 2004-2006 förberedde ett eventuellt regeringsskifte efter valet 2006 så var den s.k. Äntringsstyrkans arbete mycket viktigt. Ett av deras viktigaste förslag var att en mekanism för all samordning mellan de fyra partierna skulle inSince fall 2006, the legislative process has a new element. An unregulated and almost unknown element, however very important. When the four center right wing parties during the years 2004-2006 were preparing a possible change of government after the 2006 election, the work of the so-called “Äntringsstyrkan” was very important. One of their main proposals was that a mechanism for all coordination

Min studie har varit att med hjälp av min närläsningsmetod göra nedslag i Gunnar Björlings sena poesi och därmed visa att Björlings språk är ett komplext språk och systembygge som trots att det bär på (nödvändiga) materiella språkliga byggstenar ändå äger ett friläggande av vardagsspråklig förväntan som möjliggör ett förnimmande och närmande till en obegränsning. Vad denna obegräsning är och hur d

Några ingångar till Gunnar Björlings författarskap 1922-33 Abstract: Mitt syfte med uppsatsen om den finlandssvenske diktaren Gunnar Björling har varit att undersöka hans första produktion mellan 1922-33 som brukar nämnas Björlings modernistiska period. Jag har under uppsatsens gång försökt svara på mina frågor: 1) Vad innebär den andre som Du för Björling?, 2)Hur det relativa påverkar Björlings e

Uppsatsen undersöker hur den danske 1400-talsöversättaren av Thomas à Kempis’ Quattuor libri de imitatione Christi transformerar latinets genitivkonstruktioner till gammaldanska. Särskilt intresse vigs åt omskrivande översättningsförsök, i synnerhet dem medelst preposition. Det konstateras ett samband mellan omskrivning medelst preposition och latinska verbalsubstantiv resp. gerundier böjda i geni

The Euler equations consist of conservation laws and describe a fluid in motion without viscous forces and heat conduction. They are non-linear and the solutions are often discontinuous. Therefore proofs of convergence are hard to give and the existing results are lacking. A new concept are weakly imposed characteristic boundary conditions, where a priori given boundary data only enter the scheme

This Masters’ Thesis aimed to explore the possibilities that the new generation of portable hardware called wearables presents us with. More powerful and smaller devices with a wide array of sensors and cameras are not only becoming possible, but available at prices that are affordable to the average consumer in the first world. But as powerful as modern day technology is, things such as advanced

In this report, a doping evaluation of MOCVD grown InP nanowires catalysed with nanoimprint defined gold particles have been performed with 4-probe resistivity measurements and spatially resolved Hall measurements. The evaluation is a first step to produce tandem junction nanowire solar cells with nanowires consisting of indium-gallium-phosphide on top of indium-phosphide as an attempt to beat the

ABSTRACT Author: Ulrika Sandén Title: Contentment in the moment (translated title) Supervisor: Lars Harrysson and Hans Thulesius This is a Classic Grounded Theory study aiming at understanding the everyday life in Polarfjorden, a Northern Norwegian rural and historically isolated area. After four and a half years of observations and interviews three concepts emerged, explaining how old survival

More and more findings have been published showing that sedentary behavior is causing health hazards that can be independent of the effects from physical activity. Even if you go to the gym every day you might still suffer health effects from your otherwise sedentary life. Sicknesses as obesity, metabolic syndrome, diabetes and back pain are strongly related to the sedentary lifestyle. To instead
