Blue diode lasers emitting 5 mW continuous-wave power around 400 nm have recently become available. We report on the use of a blue diode laser together with a 30 mW red diode laser for sum-frequency generation around 254 nm. The ultraviolet power is estimated to be 0.9 nW, and 35 GHz mode-hop-free tuning range is achieved. This is enough to perform high-resolution ultraviolet spectroscopy of mercu
Popular Abstract in Swedish Växter är en av den största grupperna av organismer på jorden. Den här gruppen av organismer kan syntesisera kolhydrater med solenergi. I växter används en stor del av kolhydraterna till att bilda förnyelsebara polysackarider som sedan används för att bygga upp vedstrukturer. Den mest kända växtpolysackariden är cellulosa som består av långa kedjor av glukos. Den näst mHemicellulose is the second most abundant group of renewable polysaccharides. Mannans can be found as the major hemicellulose in softwood and as storage polysaccharides in a range of plants. In this work, structural and functional characterisations of family 5 and 26 endo-1,4-b-mannanases (b-mannanases) have been performed. These families belong to the large and diverse glycoside hydrolase clan A,
The major histocompatibility complex (MHC) genes are the most polymorphic genes found in the vertebrate genome, and they encode proteins that play an essential role in the adaptive immune response. Many songbirds (passerines) have been shown to have a large number of transcribed MHC class I genes compared to most mammals. To elucidate the reason for this large number of genes, we compared 14 MHC c
The exchange of persistent organic pollutants (POPS) between different compartments of a typical mature boreal forest was investigated. The study focused on fluxes of polychlorinated biphenyls (PCBs) between the atmosphere, vegetation and soil, and within the soil to assess whether this type of forest acts as a final sink-or temporary repository for POPs. The study, at a Swedish site, suggested to
ABSTRACT Title: Micro-Credit and Loans: Credit Riskmanagement Differences Seminar date: 2010-01-21 Course: NEKK01 - Bachelor Essay, 15 ECTS Author: Philip Thuresson Supervisor: Anders Vilhelmsson Ph.D. Keywords: Micro-credit, Risk, Yield Purpose: The purpose of this essay is to examine the differences in the risk analysis and credit process between micro-credit institutions and banks. Theoretical
This report covers a study that documents the status of BIM uses of two leading companies in the construction industry. What makes this study interesting is that, to date, there has previously not been an objective status report recording of BIM usage in Sweden. It would be of great value to test a method of assessment in Sweden to enable comparisons to be made and inform the nation of how far the
Technology is often used as a method in memory intervention but there is a gap between what we know about memory processes and the interaction with technology tools (Topo, 2009; Dascal & Dror, 2005; Hjälmedelsinstitutet, 2011). This study aims to investigate how human use our memory in a real world setting and how we valuate a technological memory tool developed to support mild memory decline.
Climate change is expected to have profound ecological effects, yet shifts in competitive abilities among species are rarely studied in this context. Blue tits (Cyanistes caeruleus) and great tits (Parus major) compete for food and roosting sites, yet coexist across much of their range. Climate change might thus change the competitive relationships and coexistence between these two species. Analys
Introduction: Research and healthcare services struggle to fulfil the desires and needs of nursing home residents, and there is a call for person-centredness in both research and healthcare practice. Involvement of people outside academia in research has been advocated in an effort to increase the relevance and impact of research findings for the public. However, little is known on how to involve
Research shows that young people within ethnic minorities are subjected to police control more often than others, which seems to have a damaging effect on their trust in the police as well as on their wider sense of belonging. What is less often researched is how these young people deal with being over-policed. This article explores narratives of over-policing from those targeted by the police in Research shows that young people within ethnic minorities are subjected to police control more often than others, which seems to have a damaging effect on their trust in the police as well as on their wider sense of belonging.

Among adolescents, loneliness is common. One kind of loneliness, existential loneliness, is understood as a painful part of the human condition. During adolescence, existential loneliness has been shown to be challenging to navigate independently. Therefore, this study aimed to explore Swedish adolescents’ experiences of existential loneliness regarding receiving and providing support. This study
This paper constructs annual GDP estimates for Ireland (1924-47) to join the first complete official aggregates. The new series is deployed to revisit Ireland’s economic performance in the post-independence decades. Ireland’s economy grew at 1.5 per cent per annum and average living standards improved by 40 per cent. The bulk of this growth was due to labour productivity improvements. Starting in
Background: Mental health problems among adolescents is a global challenge. During the transition to adolescence, physiological, psychological, and social changes occur, leading to increased vulnerability. Thus, adolescent boys are less likely to seek help for mental health problems, which makes them an undetected group. The aim of this study was to gain a deeper understanding of adolescent boys’
Authors: Petter Englund and Oscar Stenström Title: LVU - with a licence to care? A discourse analytic focus on custodians, children's perspective and social authorities [Translated title] Supervisor: Eva Palmblad Assessor: Anders Östnäs The focus of this paper was to study how the parents/caretakers and best interest of the child were portrayed and constructed in LVU (The Care of Young Person
The aim of this study was to get a greater understanding of how preschool teachers describe and handle mandatory reporting and suspicions of child maltreatment. The study was based on qualitative semi-structured interviews with six pre-school teachers. Profession theory and a dramaturgical perspective were used in the analysis. The results in the study found that preschool teachers frequently use
Ukraine has the second highest rates of the human immunodeficiency virus (HIV) in Europe and struggles with the HIV epidemic since the 1990s. Adolescent girls and young women (AGYW) are especially vulnerable due to their social position and biological characteristics. The HIV incidence is still on the rise, which is also fostered by the ongoing conflict in the East, although a great number of nati

Recent advancements in web development have made it possible to leverage the mobile device’s AR capabilities and deliver immersive content directly in the browser. The web-based immersive content may constitute a future platform for instructions and
Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot
The purpose of this study is to examine how social workers in Sweden engage in policy practice to influence policies, guidelines and methods that contradict their professional values. Based on Hirschman’s theory of exit, voice and loyalty, we analyse social workers’ strategies for change. The study problematizes some challenges social workers face in order raise their voices, but focuses on possib
