Global wetlands are the largest and most uncertain natural source of atmospheric methane (CH4). The FLUXNET-CH4 synthesis initiative has established a global network of flux tower infrastructure, offering valuable data products and fostering a dedicated community for the measurement and analysis of methane flux data. Existing studies using the FLUXNET-CH4 Community Product v1.0 have provided inval
Background: This project plan proposes a new learning activity and assessment model of medical students' empathy and communication skills. An empathic ability and communication skills are crucial in a student future role as a physician. Empathy and communication skills are also Entrustable Professional Activities in most undergraduate medical educational programs1.Method: The students are first in
The improvements in GPU hardware, including hardware-accelerated ray tracing, and the push for fully dynamic realistic-looking video games, has been driving more research in the use of ray tracing in real-time applications. The work described in this thesis covers multiple aspects such as optimisations, adapting existing offline methods to real-time constraints, and adding effects which were hard
Biodiversity is in decline due to human-induced pressures on ecosystems around the world. To be able to counteract this alarming trend, it is paramount to closely monitor biodiversity at global scales. Because this is practically impossible with traditional methods, the last decade has seen a strong push for new solutions. In aquatic ecosystems, the monitoring of species from environmental DNA (eD
Background: Different tau biomarkers become abnormal at different stages of Alzheimer’s disease (AD), with CSF p-tau typically being elevated at subthreshold levels of tau-PET binding. To capitalize on the temporal order of tau biomarker-abnormality and capture the earliest changes of tau accumulation, we selected a group of amyloid-β-positive (A+) individuals with elevated CSF p-tau levels but ne
Homeowners are facing worse personal finances with high inflation and increasing interest rates. New groups are at risk of overindebtedness and foreclosure. The entire household, including children, are affected by worse health and well-being. This leads to large societal costs. Hence, it is imperative to break the negative cycle of overindebtedness for these households. Foreclosure is enforced by
This study investigates possible structural changes of an intrinsically disordered protein (IDP) when it adsorbs to a solid surface. Experiments on IDPs primarily result in ensemble averages due to their high dynamics. Therefore, molecular dynamics (MD) simulations are crucial for obtaining more detailed information on the atomistic and molecular levels. An evaluation of seven different force
To assess the biodiversity consequences of contemporary land-use trends in Northern Europe, where agriculture is being replaced by forestry, we need a better knowledge of the contributions of constituting habitats to biodiversity. Here, we use purposefully collected data from 87 sites to model how agricultural habitats, including semi-natural pastures, sown temporary grassland (leys), cereal crops
The energy scaling of integrated circuits has reached its limit because the operating voltage of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) based switches has reached its minimum value. MOSFETs are limited by thermionic emission and cannot achieve a subthreshold swing (SS) below 60 mV/decade at room temperature. Tunnel Field-Effect Transistors (TFET), which operate on field modula
Invasive species are predicted to adjust their morphological, physiological and life-history traits to adapt to their non-native environments. Although a loss of genetic variation during invasion may restrict local adaptation, introduced species often thrive in novel environments. Despite being founded by just a few individuals, Bombus terrestris (Hymenoptera: Apidae) has in less than 30 years suc
Background and Purpose - Aortic valve stenosis may lead to atrial and ventricular remodeling, predisposes to atrial fibrillation, and may also be an independent risk factor of ischemic stroke. However, information on stroke rates among persons with aortic valve stenosis are sparse. We aimed to determine the incidence rates and relative risks of ischemic stroke in individuals with diagnosed aortic
Since 1984, 577 knee arthroplasty operations were performed in Al Razi Orthopedic hospital in Kuwait. An increase in the number of these operations occurred during the last four years and in 2007 there were almost 100 knee arthroplasty operations performed. Six out of seven operated patients were female. The mean age at operation was 67 years for male and 62 years for female patients. The vast maj
The thesis examines the new media landscape were politics and social media play central parts. In Sweden Piratpartiet, or the Pirate Party has grown in popularity and much of the success is earned thanks to the party’s political strategy in social media. Since the phenomena of social media is new and therefore not examined in academic studies, the essay’s purpose is to map out how social media is
Background: Mass customization has been identified as a competitive business strategy by both companies and academics because of its ability to incorporate the voice of the customer into companies’ products and services. Although mass customization may sound appealing, the strategic concept is still developing and firms adopting this business strategy face several challenges. Production concerns a
Syftet med uppsatsen är att få en djupare förståelse för kvalitetmätningsverktyg Mystery Shopping, belysa möjligheten att tillämpa verktyget inom delar av den svenska turismnäringen samt genom att presentera ett nytt begrepp, skapa underlag för ett nytt forskningsfält som avser Mystery Tourism.En mystery tourist kan undersöka och utvärdera en eller flera av turismproduktens moment vid samma besök/
Klinisk kemi på Helsingborgs lasarett analyserar prover från sjukhuset, kringliggande vårdcentraler och prover från patienter som kommer till den närliggande provtagningscentralen (PTC). En önskan om att erbjuda ett one stop clinic-koncept till ett antal diabetespatienter har växt fram. Det skulle innebära att patienterna kommer för provtagning till PTC och besöker läkaren vid ett och samma tillfäThe division of Clinical Chemistry at Helsingborg Hospital analyses human biological samples from the hospital, adjacent care centres and from patients who take the samples at the neighbouring centre (PTC). The division of Clinical Chemistry has a vision of being able to offer a one stop clinic-concept to a group of patients diagnosed with diabetes. This would mean that the patient could take the
Lantmännen är en av Nordens största koncerner inom livsmedel, energi, maskin och lantbruk med en omsättning på 35 Miljarder SEK. Lantmännen har under senare tid sett ett ökat behov av att minska sitt operativa rörelsekapital i ledet att frigöra bundet kapital och öka sin lönsamhet. Som en del i detta större projekt har Lantmännen insett behovet av att ha en väldefinierad lagerränta för att på ett
