Background: Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED
PURPOSE: Epinephrine is used in local anesthetics to induce vasoconstriction and thus reduce bleeding and prolong the anesthetic effect. Finding the optimal delay between the administration of the anesthetic and skin incision to ensure vasoconstriction and minimize bleeding is important and has recently become the subject of debate. This is the first study to assess blood perfusion and oxygen satu
This thesis presents an application of machine learning techniques in a search for a high-mass resonance particle decaying into top quark pairs in high energy dijet events using the ATLAS experiment at the Large Hadron Collider. Top tagging is applied to the dijet events to select the events with top signature and suppress the background, increasing the sensitivity of the search. All the data used
Following the UNHCR:s launch of the #IBelong Campaign to End Statelessness by 2024 in November 2014, a Global Action Plan to End Statelessness: 2014 – 2024 was adopted urging states to undertake ten actions to end statelessness, including to facilitate the naturalization of stateless migrants. While the facilitated naturalization of stateless persons would certainly reduce the occurrence of statel
Germany’s Energy Concept aims to reduce the building sector’s primary energy demand by 80% compared to 2008 levels, of which 20% are to be achieved by 2020. This requires significant investment in integrated renewables and thermal. Public funds cannot finance such transition alone. Therefore, it is crucial to not only understand current investment levels and potential investment gaps, but also to
Celiac disease is a chronic autoimmune disease which affects about 3 % of children in Sweden where most of them have an asymptomatic form making it difficult to detect. The bacterial composition in the gastrointestinal microflora can affect the intestinal barrier properties and the immune systems response to various dietary components. An unfavourable composition of the microflora can activate par
The aim of this thesis work was to investigate and evaluate new possible industrial applications for large welded plate heat exchangers, with heat transfer areas of at least 500 m2. The research has been carried out through thermal design of heat exchangers for a total of nine cases. The nine cases are real-life applications for processes covering the petrochemical, oil & gas, power, and refin
With the foreign political turbulence after the fall of the Berlin Wall, the world came into a change. The post-cold war environment meant that the politics of the bipolarity no longer were the case. This period leads to pressure in redefining Sweden’s foreign and security policy, resulting in an emergence of a different commitment to the countries neutrality and non-alignment. In the light of Kje
This thesis will examine the plausibility of exchanging protocol from a normal server-client to a peer-to-peer solution for over-the-air updates, using a single case study for Sony Mobile Communications AB in Lund, Sweden. It will examine the effort, the risks, and what the actual gain may be comparing to a client-server approach for over-the-air software updates. Sony Mobile today uses a content
This thesis is a descriptive case study of the institutional measures to improve women’s representation in Chile between 2015 and 2022. Women in Chile have historically been underrepresented because of two institutions introduced by former dictator Pinochet: the 1980 constitution and the binomial electoral system. In 2015, Chile reformed its electoral system to replace the binomial system with a
Under the background of the rapid development of social media, video storytelling plays an essential role in the development of a brand. More and more videos with the personal brand have become popular among the public. However, in the context of the storytelling approach, personal branding through storytelling has been rarely reported in the literature. In this study, showing the YouTuber, Li Ziq
Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to b
The main drivers of the alarming biodiversity decline are land use and land use change, primarily due to agriculture. It is therefore important to assess the impact on biodiversity caused by production of food and to do so, life cycle assessment (LCA) is a method widely used. Since the UNEP-SETAC provisionally recommended the method by Chaudhary et al. (2015, updated 2018) for impact assessments o
The enzyme dermatan sulfate epimerase 1 epimerizes glucuronic acid on chondroitin sulfate into iduronic acid giving dermatan sulfate resulting in increased flexibility of the glycosaminoglycan. The increased flexibility results in changed interactions with some proteins such as growth factors, cytokines, and angiogenic factors, and recent studies suggest that it also plays an important role in the
In this study, the production of enantiomerically pure (1R,4S,6S)-6-hydroxy-bicyclo[2.2.2]octane-2-one ((-)-2) through stereoselective bioreduction was used as a model reaction for the comparison of engineered Saccharomyces cerevisiae and engineered Escherichia coli as biocatalysts. For both microorganisms, over-expression of the gene encoding the NADPH-dependent aldo-keto reductase YPR1 resulted
Background: We recently reported (Curr Biol 22:683-688, 2012) that the eyes of giant and colossal squid can grow to three times the diameter of the eyes of any other animal, including large fishes and whales. As an explanation to this extreme absolute eye size, we developed a theory for visual performance in aquatic habitats, leading to the conclusion that the huge eyes of giant and colossal squid
Acute management of traumatic brain injury (TBI), in particular mild TBI, focuses on the detection of the 5-7 % who may be harboring potentially life-threatening intracranial hemorrhage (IH) using CT scanning. Guidelines intending to reduce unnecessary head CT scans using available clinical variables to detect those at high IH risk have shown varying results. Recently, the Scandinavian Neurotrauma
Study objectives: A method for medication reconciliation that reduces medication errors and healthcare contacts when a patient is discharged from hospital, LIMM-DI (Lund integrated medicines management-discharge information) had been previously developed by the authors. LIMM-DI is structured information written for the patient and sent to the next caregiver. In this study, the use (implementation
Exposure to some pesticides and persistent organic pollutants (POPs) has been indicated to be a risk factor for non-Hodgkin's lymphoma (NHL). Epstein-Barr virus (EBV) has been associated with some subgroups of NHL. In a previous study we found an interaction between high concentrations of some POPs and titres of antibodies to EBV early antigen (EA IgG) in relation to NHL. In the present study we m
Purpose. The aim was to examine if the retinal circulation in the pig can be accessed using interventional neuroradiology and to explore the possibility to create occlusions that result in experimental retinal ischemia. Methods. Six experiments were performed using 100 kg pigs. The external carotid system was catheterizised using fluoroscopy monitored, transfemoral, endovascular approach. Transien
