Social networks and social support are known contributors to health for people in all ages and may be of particular importance for older age groups (2008). There is a rich research tradition on older people’s social networks and during the last decades researchers have analyzed the meanings of these networks from different perspectives. Already in the early 1970s Granovetter (1973, 2005) put forwa
Popular Abstract in Swedish Denna avhandling handlar om utveckling och tillämpning av metoder för jonstråleanalys av lätta ämnen (lättare än ungefär aluminium), framförallt vid en nukleär mikrosond. Vid en nukleär mikrosond accelereras tunga partiklar, t.ex. protoner, av en partikelaccelerator och fokuseras av ett speciellt magnetiskt linssystem ned till en storlek av ungefär 1 mikrometer. Denna sThis thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods. Several signals are acquired simultaneously, and the d
Popular Abstract in Swedish De flesta produkter som vi dagligen använder tillverkas genom att utnyttja fossila råvaror som olja, kol och naturgas. Ett stort problem är att dessa råvaror bara finns i begränsade mängder i naturen, vilket medför att de förr eller senare tar slut. Dessutom medför förbränning av fossila råvaror att det bildas miljöskadande gaser (t.ex. koldioxid) som ansamlas i atmosfäOne of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. However, such utilisation requires the extraction of the biopolymers from th
In this paper we present a new method to electrodeposit highly porous gold (h-PG) onto a polycrystalline solid gold electrode without any template. The electrodeposition is carried out by first cycling the electrode potential between +0.8 and 0 V in 10 mM HAuCl4 with 2.5 M NH4Cl and then applying a negative potential for the production of hydrogen bubbles at the electrode surface. After that the m
In the last years we have witnessed an increased number of experimental performances that engage with children. Shows made in collaboration and/or performed by children. Children on stage, children as our tour guides through cities, children leading us though darkness. There are many ways to analyze this ‘interest’ including curatorial schemes encouraging participation, funding agendas, institutio
We consider the potential for positioning with a system where antenna arrays are deployed as a large intelligent surface (LIS), which is a newly proposed concept beyond massive multi-input multi-output (MIMO) where future man-made structures are electronically active with integrated electronics and wireless communication making the entire environment "intelligent". In a first step, we derive Fishe
Effects of the bluff-body's position on diffusion flame structures and flame instability characteristics were investigated experimentally. A flame regime diagram together with the corresponding flow fields were proposed to evaluate the influences caused by the alternation of bluff-body's position. The disk shape bluff-body was placed 10 mm downstream or at the same height with the annular channel
This thesis comprises three papers studying several mathematical models related to geometric Markov processes and random processes with reinforcements. The main goal of these works is to investigate the dynamics as well as the limiting behaviour of the models as time goes to infinity, the existence of invariant measures and limiting distributions, the speed of convergence and other interesting rel
In education programs with an artistic ground, i.e. where the student is supposed to develop an artistic skill, the overall objective is to provide the fundament for a practitioner to become a well functioning individual in a specific artistic community. This artistic community of practice plays – directly through professionally active teachers, and indirectly through teachers with a good understa
Normative reasons are of constant importance to us as agents trying to navigate through life. For this reason it is natural and vital to ask philosophical questions about reasons and the normative realm. This thesis explores various issues concerning reasons and normativity. The thesis consists of five free-standingpapers and an extended introduction. The aim of the extended introduction is not me
BACKGROUND: Higher fasting Growth Hormone (GH) has been associated with increased cardiovascular morbidity and mortality. Our objective was to find genetic determinants of fasting GH in order to facilitate future efforts of analyzing the association between fasting growth hormone and cardiovascular disease. A genome-wide association study (GWAS) was performed in a discovery cohort of 4134 persons
This presentation draws upon an ongoing research project that explores learning of Swedish folk music across six learning areas. These areas span from what is generally considered formal arenas to informal ones:(A) Music academy (performers programme), (B) Folk high school (full time course), (C) Folk high school (distance course), (D) Fiddlers’ group (spelmanslag), (E) Professional musicians, (F)
Increasing iron (Fe) concentrations have been reported for freshwaters across northern Europe over the last decades. This increase, together with elevated concentrations of dissolved organic carbon (DOC), leads to browning of freshwaters, which affects aquatic organisms, ecosystem functioning, biogeochemical cycles, and brings challenges to drinking water production. However, how such increasing t
Biodiversity loss is recognized as a grand challenge of the twenty-first century but ascertaining when a species is “lost” can be incredibly difficult—since the absence of evidence is not evidence of absence. This may be a relatively easy task for large and conspicuous animals, but extremely difficult for those living hidden lives or at low population sizes. We showcase this challenge by focusing
The galloping pace of development in the field of wireless communication has left the world astounded over the last decade. But this has also led to a wild and inexcusable extravagant expenditure of energy. Due to the dynamic nature of wireless network, it has become imperative to focus more on energy efficiency and achieve desired Quality of Service (QoS). The challenge of diminishing the carbon
Under de senaste åren har tekniska lösningar på finansmarknaden ökat, framförallt med utvecklingen av appar. Den mer klassiska bankverksamheten samverkar nu med nya lösningar som hjälper konsumenterna med sina finansiella tjänster, många från så kallade FinTech-företag. Beträffande betalningstjänster har ett nytt direktiv som kallas PSD2 nyligen genomförts inom EU. Direktivet har, som ett av sina During the last years, technical solutions on the financial market has increased, especially with the developments of apps. The more classic banking is now co-excising with new solutions that help consumers with their financial services, many from so-called FinTech companies. In regard of payment services, a new directive called PSD2 has recently been implemented within the EU. This directive has,
In the fall of 2007 a collective of artists in southern Sweden made waves for themselves by attempting to construct a rather unique ‘club-format’ unlike any other in the [then] current Swedish underground club scene. Guided mainly by a self-proclaimed ‘notion of confusion’ as its foundational principle, the collective behind Klubb Kristallen branded itself as an aspiring anti-club by seeking to ch
Båtklubben i Kiviks hamn har länge upplevt problem med stora vågor i hamnbassängen. Denna studie ämnar att fastslå vilka vågförhållanden och fenomen som ger upphov till dessa problem, samt att föreslå åtgärder. En undersökning av vågklimatet utanför hamnen utförs med hjälp av en enkel modell, kallad SPM, som beräknar en tidsserie vågor utifrån meteorologisk och geografisk data. För att kartlägga vThe yacht club in Kivik marina has experienced problems with large waves in the harbour basin for a long time. This study aims to determine the wave conditions and phenomena that give rise to these problems, and to propose measures. An investigation of the wave climate outside the harbour is carried out using a simple model, called SPM, which calculates a time series of waves based on meteorologic
The aim of this essay is to shed light on a part of the human consciousness that has been given little attention in the history of ideas, the dream. Through a historicizing of dreams, this essay wants to make history out of something natural, a way to see culture where there used to be nature. This is done by looking at three explanations of dreams, from different points in time, in order to exami
