Background and aims: Good Selenium (Se) status predicts favorable prognoses for various diseases and a reduced overall mortality. The primary objective of the study was to determine whether Selenium status, i.e. Selenoprotein P (SeP) levels, is associated with risk of 90-day mortality in elderly patients with acute dyspnea at the Emergency Department (ED). Methods and results: Patients presenting
Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwarf component for which direct measurements of these stars' masses and radii are difficult using other techniques. Within the potential of M-dwarfs to be exoplanet host stars, the accuracy of theoretical predictions of the
Emotions are prominent in the construction of notions of citizenship. A good liberal-democratic citizen, for instance, cares about others, copes with differences and trusts the political system (Zembylas 2013). Increasing political polarization challenges teachers to prepare youth as citizens who can navigate ideological and affective boundaries (Keegan, 2021). More specifically, emotions play an
Relationship marketing is getting more focus from researchers today. The idea of earning the trust and loyalty of customers by engaging in relationships has been put to practice in many retail areas. Retailers and researchers are stressing the importance of establishing relationships with their customers and are in many ways focused on the physical service encounter. Literature often suggests that
Saint Olav His Cult The subject of this thesis is Saint Olav (995-1030) and his cult in medieval Scandinavia. He was canonized soon after his death, and he became a popular saint in the Scandinavian countries. With the help of the material and historical evidence of the cult of Saint Olav I here attempt to trace who was the driving force behind its expansion, as well as why the cult was spread wi
Eld är en av de viktigaste störningsprocesserna som påverkar den terrestra biosfären genom att forma vegetationens spridning, komposition, struktur, växtdiversitet och biokemiska cykler. Några av de mest påverkade ekosystemen är våt-torra områden, här klassificerade som savann eller Medelhavsområden. Denna påverkan kan studeras på olika sätt, antingen genom ett långvarigt och fortlöpande experimenFire is one of the most important disturbance processes affecting the terrestrial biosphere, altering the vegetation composition and distribution, structure, plant diversity and biogeochemical cycles. Some of the most influenced ecosystems are wet-dry areas, here classified as savannah or Mediterranean regions. The influence can be studied in different ways, either by long-term experiments like th
Abstract The significance of terrestrially derived iron (Fe) for marine ecosystems and its implications on other biogeochemical cycles is well recognised. It has been recently highlighted that the concentration of Fe in several Swedish rivers has increased strongly over the last 40 years. Four rivers draining into the Baltic Sea were used in the present study in order to assess the aggregation pr
A proposer to a marine insurance contract is subjected to a pre-contractual duty to disclose material information under the doctrine of utmost good faith (uberrimae fidei). The duty extends to comprise matters that concern moral hazard and the shipping company may consequently be required to volunteer information concerning the moral character of its owners, directors, employees and other agents c
Rapporten är en del av kursen Brandteknisk Riskvärdering vid Lunds Tekniska Högskola. Syftet är att analysera och utvärdera personsäkerheten på Confidencen, Ulriksdals Slottsteater, vid händelse av brand. Confidencen är byggnadsminnesmärket och är Sveriges äldsta rokokoteater som bedriver teater- och operaverksamhet. Publiken består till mestadels av äldre personer där byggnaden rymmer maximalt 25This rapport is a part of the course “Brandteknisk riskvärdering” given at Lund University of Technology. The purpose of this report is to evaluate the fire safety and evacuation possibilities of the theater Confidencen with the focus on personal safety of the people in the building. If necessary, suggestions of improvements in the fire safety will be provided. Confidencen is the oldest Rococo the
Voluntourism is often described as a sustainable development strategy facilitating Global Learning and cross-cultural exchange. Initiated by the German Federal Ministry for Economic Cooperation and Development (BMZ), the voluntourism program Weltwärts strives to create stronger international partnerships, development engagement, and equitable encounters. The practice of voluntourism is contested,
Videospelsbranschen växer ständigt och globalt omsätter den idag flera hundra miljarder kronor. Bakom varje enskild speltitel ligger omfattande investeringar av både tid och kapital. Upphovsrätten är den immaterialrätt som ger skydd åt videospel. Att spelutvecklarna kan erbjudas ett effektivt skydd är essentiellt för branschens fortsatta utveckling. Omfattningen av, och formerna för, det upphovsräEvery year video game sales reach beyond several billion USD globally and the video game industry is ever expanding. The production of a single game title requires substantial investments of both time and capital. Video games are protected by copyright. Effective copyright protection is essential for the industry’s continued development as it is a major economic incentive for the creation of video
Food loss is of great importance considering its waste of natural resources and the negative environmental impact caused by the food industry. To reduce food loss, some actors donate, produce and retail what we here entitle circular food products: products made from food loss. However, the market for these types of products is neither stable or certain and there is a need for increasing the value
Morphology, structure and chemistry have been investigated for 17 different commercial graphenegrades,all labeled as different kinds of graphene powder. For objectivity reasons, all powders have been given names as Graphene A-Q instead of their real product names. Out of the 17 tested powders, only Graphene A and B showed consistent results of being graphene-like. All powders have been characteriz
Introduction: In recent years omni-channel retailing has been accepted and used by both physical and e-commerce retailers. In omni-channel retailing different channels are integrated. An effective and efficient distribution system is becoming more crucial. The core of the distribution system is warehousing that affects lead time and logistics cost. The main challenge is to handle large store reple
Denna uppsats handlade om antisocialt beteende kopplat till (upplevd) självförmåga (selfefficacy) och självkänsla (self-esteem). Syftet var att undersöka ifall det finns en korrelation mellan grad av antisocialt beteende och grad av självförmåga och självkänsla. Hypotesen är att ju högre grad av antisocialt beteende desto högre grad av självförmåga och lägre grad av självkänsla. Metoden som användThe purpose was to examine if there is a correlation between the level of antisocial behaviour and level of self-esteem and self-efficacy. The thesis was that the higher level of antisocial behaviour correlates with a higher level of self-efficacy, but a lower level of self-esteem. The method used was online survey, with a total of 111 participants between the ages of 18 and 30. The survey consist
The aim of this study was the investigation of the photocatalytic properties of Iron{phenyl[tris(3-methylimidazole-2-ylidine)]borate}2 ([Fe(phtmeimb)2]+) by optimising reactions previously established with ruthenium-based catalysts in good yields. For the first time in several decades of research on photochemistry of iron complexes a Fe complex has been made ([Fe(phtmeimb)2]+) that has photophysic
During the last few years, the interest for electric vehicles has increased enormously, there are even talk of prohibiting fossil fuels in the coming years. There is a risk that the charging of these electric vehicles can strain the electric grid. The simulations of the grid with added power demand from the electric vehicles concludes that there will not be a problem on the low- and medium voltage
