ABSTRACT: We plan to conduct a case-control study to investigate whether exposure to nitrogen dioxide (NO2) increases the risk of stroke. In case-control studies, selective participation can lead to bias and loss of efficiency. A two-phase design can reduce bias and improve efficiency by combining information on the non-participating subjects with information from the participating subjects. In ou

Stratospheric ozone levels are near their lowest point since measurements began, so current ultraviolet-B (UV-B) radiation levels are thought to be close to their maximum. Total stratospheric content of ozone-depleting substances is expected to reach a maximum before the year 2000. All other things being equal, the current ozone losses and related UV-B increases should be close to their maximum. I

Twenty years after Vassar College welcomed the first American female undergraduates in 1865, the experiences of women college students began to be fictionalized in so-called college stories. This thesis shows how higher education is presented in the novels, collections of short stories, and serialized stories for female readers published before the United States was involved in the First World Wa

Purpose: Hematoma volume is the strongest predictor of patient outcome after intracerebral hemorrhage (ICH). The aim of this study was to validate novel fully automated software for quantification of ICH volume on non-contrast computed tomography (CT). Methods: The population was defined from the Swedish Stroke Register (RS) and included all patients with an ICH diagnosis during 2016–2019 in Regio

Objectives: To assess if improvement of working conditions related to heat stress was associated with improved kidney health outcomes among sugarcane harvest workers in Chichigalpa, Nicaragua, a region heavily affected by the epidemic of chronic kidney disease of non-traditional origin. Methods: Based on our findings during the 2017-2018 harvest (harvest 1), recommendations that enhanced the rest

PURPOSE: Proactive management of type 2 diabetes is important for restoring beta-cell function and improving sustained blood glucose control. Evidence on quality of diabetes care in Ethiopia is inadequate.METHOD: Facility-based cross-sectional study was conducted to assess level of quality of care provided to adult type 2 diabetes patients at three public hospitals in Gamo Gofa Zone, Southern Ethi

Objective: To evaluate the influence of implant and prosthetic components on peri-implant tissue health. A further aim was to evaluate peri-implant soft-tissue changes following surgical peri-implantitis treatment. Materials and methods: Group discussions based on two systematic reviews (SR) and one critical review (CR) addressed (i) the influence of implant material and surface characteristics on

I takt med att andelen variabel förnybar energi ökar i det svenska elsystemet krävs nya lösningar för att hantera utmaningar kopplade till intermittens, nätstabilitet och ekonomisk lönsamhet. Batterilagringssystem (BESS) lyfts fram som en av de mest lovande lösningarna för att möta dessa utmaningar. Detta examensarbete undersöker den tekniska och ekonomiska genomförbarheten av att integrera BESS mAs the share of variable renewable energy (VRE) increases in the Swedish electricity system, new solutions are needed to address challenges related to intermittency, grid stability, and economic viability. Battery energy storage systems (BESS) have been identified as one of the most promising solutions to meet these challenges. This master’s thesis investigates the technical and economic feasibili

Att använda hur ljus absorberas för att ta reda på något om ett ämne är inget konstigt, vi har alla gjort det. När vi blandar ett glas saft tittar vi på färgen och kan säga av erfarenhet hur stark den är. Precis på samma sätt fungerar absorptionsspektroskopi, genom att titta på hur mycket ljus som passerar genom ett material kan vi bestämma koncentrationen av ett ämne vi är intresserade av, om vi Optical spectroscopy is commonly used in technology and science today. The presence and concentration of a substance can be determined by its spectral signature, the typical wavelengths that are absorbed (or emitted) by the atoms or molecules. Standard absorption spectroscopy requires that the substance is clear and that the optical path-length is known to obtain quantitative information. Unfortun

Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem

In Europe, sustainability in the meat and dairy industry has emerged as an issue of great concern for society. Research and pressure centre on the agricultural component and little attention has been given to the processing industry despite the integral role it plays in the European meat and dairy supply chain. This thesis aims to fill this knowledge gap by identifying the current sustainability p

Pågående konflikter i Syrien, Afghanistan, Somalia och Sudan har inneburit att antalet flyktingar i världen stigit till nivåer som inte uppmäts på decennier. Barn och ungdomar utgör en stor del av de människor som befinner sig på flykt, varav vissa av dessa flyr ensamma utan stöd eller närvaro av föräldrar, syskon eller nära släktingar. I en svensk och internationell kontext benämns dessa barn somOngoing conflicts in Syria, Afghanistan, Somalia and Sudan has meant that the number of refugees worldwide has risen to levels not measured in decades. Children constitute a big part of these refugees, some of them fleeing their homes without a parent or a legal guardian. In a Swedish and international context these children are often referred to as ”unaccompanied”. This term referrers to the chil

The aim of this thesis is to build an understanding of the current instruments and mechanisms governing global supply chains and to identify the governance gaps in the protection of labour rights. In order to fully understand the implications of globalization on labour law, the thesis undertakes a theoretical framework drawing on transnational labour law perspectives and a conceptual analysis of g

Den första oktober 2019 infördes med SFS 2019:523 en lång rad lagändringar i hyreslagen. Till de viktigaste ändringarna hör 1) kriminalisering av köpare av hyreskontrakt, 2) skärpta straff för försäljning av hyreskontrakt, 3) kriminalisering av andrahandsuthyrning om hyresgästen både saknar tillstånd från hyresvärd eller hyresnämnd och tar ut ett överpris och 4) att hyresrätter inte längre kan bytOn 1 October 2019 SFS 2019:523 was entered into action, containing a long list of legal changes in the Swedish Rent Act (Hyreslagen). Among the more prominent changes were i) the criminalization of buyers of a rental contract, ii) harsher punishment for selling such contracts, iii) criminalization of tenants who both sublet the apartment without permission from the landlord or the Rental Board and

Mother tongue tuition (MTT) has been part of the Swedish educational system since 1977, with now almost 30 per cent of elementary school students eligible for the subject. With an increasingly globalized world, as well as expectations from the EU of all their member states’ citizens learning at least three languages, MTT could work as a means to meet the goal of a more linguistically knowledgeable

In our thesis we will analyze two different types of immersive and interactive technologies at two Swedish museums: Västergötlands museum and Naturhistoriska riksmuseet. For this paper we conducted field research where we visited the museums and studied two installations: a browser game called Fornbyäventyret as well as a mobile app called Nya djur, which is based on augmented reality. Our primary

Användandet av fossila bränslen är utbrett och någonting som genomsyrar hela det moderna samhället. Fossila råvaror, som olja, naturgas och kol har många användningsområden och används bland annat vid produktion av plast, som drivmedel för transport och för att producera elektricitet. Att nyttja fossila råvaror är däremot inte oproblematiskt då dessa bidrar till ökande halter av växthusgaser i atmThe waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. Cellulose is of interest to be used for bio-based materials since it has many desired properties. However, it lacks the fo

Denna uppsats berör 5 kap 6 § utlänningslag (2005:716) om ömmande om-ständigheter för barn. Bestämmelsen innebär en möjlighet att beviljas uppe-hållstillstånd när ingen annan grund finns då det skulle anses strida mot hu-maniteten att utvisa utlänningen. För barn har det sedan 2014 räckt att inneha särskilt ömmande omständigheter för att kunna beviljas uppehållstillstånd, men från 1 dec 2023 måsteThis essay addresses Chapter 5, Section 6, Subsection 2 of the Swedish Al-iens Act (UtlL) regarding compelling circumstances for children. The purpose of this essay has been to investigate the differences between ex-ceptionally compelling circumstances, but not with the same severity and gravity as for adults, and particularly compelling circumstances from a child rights perspective. This has bee

Lag (2021:787) om klimatdeklaration för byggnader anger i dagsläget inga gränsvärden för utsläpp av växthusgaser vid uppförandet av byggnader. Om ett förslag från Boverket om ändring av lagen antas kan dock gränsvärden för klimatpåverkan regleras i lag redan sommaren 2025. I väntan på lagstiftning regleras gränsvärden för klimatpåverkan i klausuler i entreprenadavtal. Syftet med denna uppsats är aThe Act (2021:787) on climate declaration for buildings currently does not state any limit values for greenhouse gas emissions during the construction of buildings. However, if a proposal from the Swedish National Board of Housing, Building and Planning regarding an amendment to the act is adopted, limit values for climate impact could be regulated by law in 2025. Pending legislation, limit values
