Lightweight wooden-framed constructions have steadily increased their market share in Sweden during the last two decades. Achieving acoustic and vibration comfort in wooden-based buildings is, however, still a challenging task. Wood is high in both strength and stiffness in relation to its weight, but its variability has repercussions on how sound propagates, this triggering sound insulation probl
Preservatives are biologically active substances mainly used in water-based products to prevent the growth of microorganisms. Most people are exposed to them on a daily basis. Formaldehyde is one of the oldest and most commonly used preservatives. However, it is a well-known contact sensitiser in dermatitis patients. The aims of this work were: i) to investigate the prevalence of contact allergy t
Background Primary Sjogren's syndrome (pSS) is characterised by a chronic inflammation of exocrine glands. Salivary gland infiltrates, however, do not correlate well with disease symptoms, and a primary role for the salivary gland parenchyma in disease development has been suggested. Specifically, dysfunction of exocrine pathways involving the muscarinic receptor 3 (CHRM3) has been indicated. Obje
Popular Abstract in Swedish Ett felaktigt protein som klumpar ihop sig i hjärnans blodkärl är orsaken till hjärnblödning och för tidig död hos unga islänningar. Sjukdomen är ärftlig och uppkommer på grund av en enda felaktig byggsten, orsakad av en mutation, i proteinet cystatin C. Det muterade proteinet bildar mikroskopiska proteinkedjor, fibriller, som klumpar ihop sig i bland annat hjärnans bloThe pathophysiological process in Alzheimer’s disease and other amyloid disorders usually involves the transformation of a soluble monomeric protein via potentially toxic oligomers into amyloid fibrils. The structure and properties of the intermediary oligomers have been difficult to study due to their instability and dynamic equilibrium with smaller and larger species. This has hampered the devel
The logistic regression model is frequently used in epidemiologic studies, yielding odds ratio or relative risk interpretations. Inspired by the theory of linear normal models, the logistic regression model has been extended to allow for correlated responses by introducing random effects. However, the model does not inherit the interpretational features of the normal model. In this paper, the auth
Abstract in UndeterminedThe MAX IV facility presently under construction will include two storage rings for the production of synchrotron radiation. Both rings will be operated at a constant 500 mA of stored current with top-up shots supplied by the MAX IV linac acting as a full-energy injector. Until recently, injection into both storage rings was designed using a conventional approach: a closed
The purpose of this study has been to investigate the service user involvement in the course “Socialt förändringsarbete” that has been offered since 2005 at the School of Social Work at Lund University. The service user involvement in this case is formed as an entire 7,5 hp course carried out by service users and social work students together. This means that the service users participate as stude
The term self-determination is embedded in much difficulty. It is a term whose meaning has developed considerably from its first intended usage. Today, in a world that is in several respects becoming smaller and more conformed, certain peoples claim rights they have previously not been granted in order to protect their subsistence and preserve their culture. The Sami is one of these peoples. This
The contemporary labour practices within the readymade garment industry in Bangladesh represent sweatshop-related working conditions. The garment workers suffer from appalling working conditions that have not existed in the global North for a couple of hundred years. The export of garments is Bangladesh’s main source of income. In order to ensure that the country remains competitive in the global
The purpose with this essay was to examine and raise a child perspective on the inset home therapy. The purpose also included to get more knowledge about how much children in middle childhood are involved in investigations and social acts, and most of all when it comes to those measures that includes children themselves. We studied this from three different perspectives: one socialworker perspecti
Immigrants that wants to come to Sweden and don´t have any visas, residence permit or passports and are not cooperative will be placed by the Swedish authorities at "förvaret". The purpose of this essay was to investigate "förvaret" in perspective of human rights and legal security. The questions at issue, which are connected to the purpose are: Are there any connections betwee
Objective: The aim of this study was to investigate self-reported hearing difficulties, uptake, and hearing-aid outcomes and their relationships to demographic, cognitive, psychosocial, and health variables in 85 year olds. Design and study sample: Three hundred and forty-six elderly adults participated in a survey that included questionnaires and home visits. Fifty-five percent of participants ad
A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315 nb(-1) collected by the ATLAS detector. No resonances were observed. Upper limits were set on the product of cross section and signal acceptance for excited-quark (q*) production as a fu
Attention allows animals to respond selectively to competing stimuli, enabling some stimuli to evoke a behavioral response while others are ignored. How the brain does this remains mysterious, although it is increasingly evident that even animals with the smallest brains display this capacity. For example, insects respond selectively to salient visual stimuli, but it is unknown where such selectiv
The hydrogen absorption mechanism of the 2NaH + MgB2 system has been investigated in detail. Depending on the applied hydrogen pressure, different intermediate phases are observed. In the case of absorption measurements performed under 50 bar of hydrogen pressure, NaBH4 is found not to be formed directly. Instead, first an unknown phase is formed, followed upon further heating by the formation of
The aim of this work has been to characterize starch based Pickering emulsions as a first step to evaluate their possible use as vehicles for topical drug delivery. A minor phase study of emulsions with high oil content has been performed. Emulsion stability against coalescence over eight weeks and after mild centrifugation treatment has been studied. The particle size, rheological properties and
We study opinion dynamics in social networks using a version of the concatenated Friedkin-Johnsen model, where the opinion evolution of the participating agents is allowed to continue over sequences of related issues. These agents have a certain associated stubbornness that anchors them to their initial opinion, which we allow them to update between issues. The central purpose of the present work
Introduction: Many countries in the world are still facing high maternal mortality rates and women still die due to preventable pregnancy- and birth-related causes. This could be prevented with an improvement in the quality of care and yet many countries, especially in the rural areas, have challenges in doing so. In order to understand why is care given in certain way, more qualitative studies ne
Offentlig upphandling bygger på EU-rättens grundläggande principer vilka bland annat syftar till att säkerställa rättvisa och konkurrens. När ett kontrakt har ingåtts är möjligheterna att ändra dess innehåll under löptiden därför strikt begränsade. Ändrings- eller optionsklausuler utgör dock ett undantag från denna huvudregel och medger ändringar av upphandlade kontrakt utan att ett nytt upphandliPublic procurement is based on the fundamental principles of EU law which aim to ensure justice and competition, among other things. Once a contract has been concluded, the possibilities to modify its content during its term are therefore strictly limited. However, review or option clauses constitute an exception to this general rule, allowing changes to procured contracts without the need for a n
In this thesis, I aim to examine and expand on different IR theories in their attempt to explain and understand the emergence of the modern international order. To do that, I used a Heideggerian ontological analysis as an analytical toolkit, based on hermeneutical phenomenology as a method. To achieve my goal, I examine the Western history of Being from Plato to Kant using a Heideggerian perspecti
