Sweden is striving to fulfill Vision Zero, a road traffic safety project that aims to prevent people from getting killed or seriously injured in traffic. To further improve safety and accessibility of the existing roads, widening of roads can be performed. The purpose of this thesis is to identify and summarize different variants of construction for road widening, using the existing data and exper
Aims: To investigate associations between trust in the healthcare system and all-cause, cardiovascular, cancer and other causes mortality. Study design: Prospective cohort study. Methods: A public health questionnaire was conducted in 2008 in Scania, the southernmost part of Sweden, with a 54.1% participation rate with a postal questionnaire and three reminders. In this study 24,833 respondents we
Som ett led i att homogenisera den kinesiska befolkningen, har den kinesiska regeringen under längre tid bedrivit en kampanj för att avskaffa Xinjiang-provinsens inhemska folkgrupp Uigurer. Massiva konverteringsläger har inrättats där Uigurerna tvingas avsäga sig sin kultur, etnicitet och religion. Situationen beskrivs av journalister och politiker som ett kulturellt folkmord, men trots begreppetsSince 2017, the Chinese government has conducted an internment campaign against the Uighur Muslim minority in Xinjiang, China, with the goal of total assimilation into the majority population. Cultural genocide has emerged as a powerful rhetorical tool to describe the treatment of the Uighurs. Despite its conceptual relevance, it does not carry any legal authority as the current understanding of g
Some network cameras have already several other sensors besides the image sensor to extend the capabilities of the camera. It is then only natural to think what can be achieved when air sensors are added into the mix. In this master thesis the applications of air sensors coupled together with network cameras have been investigated. Considering the network infrastructure is already in place, having
I den statliga utredningen, Ett snabbare bostadsbyggande, undersöktes hur utnyttjandet av byggrätter kunde effektiviseras. Underlaget var dock tämligen begränsat, vilket skapade idén till den här rapporten. I vilken utsträckning förekommer outnyttjade byggrätter och varför utnyttjas de isåfall inte? Syftet med denna rapport är att utreda om det finns outnyttjade byggrätter med ändamål flerbostadsIn the public report, Ett snabbare bostadsbyggande, a research was made to find out how the utilization of undeveloped building rights could be made more efficient. However, the material on which the research was based was found insufficient, which created the idea for this report. To what extent do undeveloped building rights occur and what are the reasons? The purpose of this report is to exami
Introduction: Infective endocarditis (IE) is a challenging diagnosis to suspect and to confirm. The purpose of this study was to clarify how often IE is suspected already on hospital admission, which clinical signs trigger the physicians’ suspicions and to investigate if the empirical treatment is adequate. Methods: A retrospective observational study of cases with definitive IE, during 2018–2019
Polycrystalline cubic boron nitride (pcBN) is a very promising tool material for turning martensitic stainless steels at high cutting speeds (vc > 200 m/min). The competitive advantage of pcBN over cemented carbide increases as the cutting speed is increased. Changing the speed might lead to a shift in the wear balance and hence the knowledge about tool wear below vc = 200 m/min might not be appli
Brain ischemia is a major cause of neurological dysfunction and mortality worldwide. It occurs not only acutely, such as in acute ischemic stroke (AIS), but also in chronic conditions like cerebral small vessel disease (cSVD). Any other conditions resulting in brain hypoperfusion can also lead to ischemia. Ischemic events can cause blood-brain barrier (BBB) disruption and, ultimately, white matter
Purpose: How national culture induces entrepreneurship and business growth remains elusive in research. Questions remain, for example, how can we determine whether a given national culture is good or bad for entrepreneurial activities? What are those pro-entrepreneurship national culture dimensions that could be promoted across nations? These questions are yet open for discussion. The purpose of t
Imidacloprid is one of the most widely used soluble neonicotinoid insecticide, which is non–volatile and persists in the soil, with hazardous effects on birds, honeybees, and mammals. It is used in both agricultural and veterinary applications, and is found in at least 7% of European topsoils. One of the commercially available formulations is Confidor O–TEQ® that exhibits higher retention, spreadi
IMPORTANCE: Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated diverticulitis with less morbidity than resection procedures. OBJECTIVE: To compare the outcomes from laparoscopic lavage with those for colon resection for perforated diverticulitis. DESIGN, S
Current syntheses of CsPbBr3 halide perovskite nanocrystals (NCs) rely on overstoichiometric amounts of Pb2+ precursors, resulting in unreacted lead ions at the end of the process. In our synthesis scheme of CsPbBr3 NCs, we replaced excess Pb2+ with different exogenous metal cations (M) and investigated their effect on the synthesis products. These cations can be divided into two groups: group 1 d
Throughout the last decades, the social responsibility of corporations has undergone significant changes. From revolving around self-regulation, voluntariness, and soft law, the regulatory landscape has expanded to involve harder demands on corporations, such as mandatory sustainability due diligence. This thesis considers these changes as a hardening of Corporate Social Responsibility (CSR), and
Research in computational mechanics is increasingly in search of methods that directly incorporate the information governed by data. Within these data-based methods, the data-driven mechanics approach seeks to replace conventional material models with discrete data sets. Offering immense potential in computational mechanics, where the simulation of complex mechanical systems is often challenging,
The effects on speeds and speed distribution were studied in a large scale field trial with an in car system for speed adaptation in the city of Lund, Sweden. In the trial 290 vehicles were equipped with an "active accelerator pedal" and data logger for a period of 3-11 months. Data was logged in each test vehicle during the whole trial and was analyzed for 3 one-month periods: Before activating t
This thesis analyses self-employment, sickness absence and early retirement pension among immigrants in Sweden. The empirical analysis investigate a period, 1981-2003, characterized by a transformation from high employment and expansion of the welfare state in the 1980s into a state with high unemployment and tightening social insurance systems during in the 1990s, This thesis goes beyond most pre
Advances in mobile and wireless technology have expanded the scope of electrodermal research. Since traditional electrodermal measurement sites are not always suitable for laboratory research and are rarely appropriate for ambulatory measurements, there is a need to explore and contrast alternate measurement locations. We evaluated bilateral electrodermal activity (EDA) from five measurement sites
Gene flow in macroalgal populations can be strongly influenced by spore or gamete dispersal. This, in turn, is influenced by a convolution of the effects of current flow and specific plant reproductive strategies. Although several studies have demonstrated genetic variability in macroalgal populations over a wide range of spatial scales, the associated current data have generally been poorly resol
