The electrical resistivity tomography (ERT) method provides moderately good constraints for both conductive and resistive structures, while the radio-magnetotelluric (RMT) method is well suited to constrain conductive structures. Additionally, RMT and ERT data may have different target coverage and are differently affected by various types of noise. Hence, joint inversion of RMT and ERT data sets
Tunnelling below water passages is a challenging task in terms of planning, pre-investigation and construction. Fracture zones in the underlying bedrock lead to low rock quality and thus reduced stability. For natural reasons, they tend to be more frequent at water passages. Ground investigations that provide information on the subsurface are necessary prior to the construction phase, but these ca
Every year, 100,000 tons of dissolved hemicelluloses are discharge unused with wastewater from thermomechanical pulp mills around the world. Isolation of these hemicelluloses from the wastewater would not only reduce the treatment costs for the pulp mills but would also provide an excellent raw material for high value applications such as oxygen barriers in food packaging. The isolation of the he
Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. SRA has been frequently used for calibration of partial factors in limit state design codes for structures (not dams). In a reliability analysis a mathematical descrip
ABSTRACT: BACKGROUND: Patients with uncharacteristic inflammatory symptoms such as long-standing fatigue or pain, or a prolonged fever, constitute a diagnostic and therapeutic challenge. The aim of the present study was to determine if an extended immunophenotyping of lymphocytes and monocytes including activation markers can define disease-specific patterns, and thus provide valuable diagnostic i
Popular Abstract in Swedish Urinvägsinfektioner (UVI) är en av våra vanligaste infektionssjukdomar och orsakas oftast av bakterien Escherichia coli (E. coli). Infektionernas svårighetsgrad varierar, beroende på samspelet mellan bakterie och värd. Njurbäckeninflammation kan orsaka allvarliga störningar av njurfunktionen och kan till och med vara livshotande. Blåskatarr är en mindre allvarlig sjukdoUrinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. The difference in disease severity reflects the virulence of the infecting strain and the propensit
Increasing concern regarding climate change and environmental sustainability have driven research regarding the development of innovative solutions for CO₂ mitigation and biomass utilization. This thesis explores the catalytic conversion of CO₂ and lignin into valuable chemicals, as a promising approach to achieving carbon neutrality and enhancing the circular economy. The study focused on two key
Numerous studies have demonstrated the significant impact of the resolution of solar irradiation data on the outcomes of hourly production models. Accurate integration of photovoltaic (PV) systems sometimes demands a high-resolution global horizontal irradiance (GHI) time series to capture the rapid fluctuations in PV power output induced by swift irradiance changes. Most of the available database
Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve. Several of them relate to the
Firefighters are occupationally exposed to a large number of toxic compounds (IARC 2010). The occupational exposure of firefighters has been classified as potentially carcinogenic (class 2B, IARC; (Straif K. et al. 2007)). Poorly quantified emission factors and low understanding of when various aerosol emissions are likely to form during a fire event (initiation, combustion, extinguishing) inhibit
Groundwater footprint index (GFI) is an essential indicator to assess the sustainability of groundwater aquifers. Prediction of future GFI can significantly help managers and decision-makers of groundwater supply to better plan for future resilient consumption of surface and groundwater. In this context, artificial intelligence and machine learning models can aid to predict GFI in view of lacking
There is widespread consensus that teamwork constitutes one of the key requirements in today’s multidisciplinary and highly complex system of delivering care. In recent years, increasing attention has been given to questions of how to define, teach, measure, and improve teamwork in healthcare. However, one cannot help but feel a certain disconnect between this ongoing trend, with an associated bia
BACKGROUND: Universal access to safe drinking water and sanitation facilities is an essential human right, recognised in the Sustainable Development Goals as crucial for preventing disease and improving human wellbeing. Comprehensive, high-resolution estimates are important to inform progress towards achieving this goal. We aimed to produce high-resolution geospatial estimates of access to drinkin
Energy use and energy feedback - An evaluation of Sweden’s largest energy saving experiment at E.ON E.ON Sverige AB is now performing Sweden’s largest energy saving experiment to see if its customers can reduce their electricity consumption just by visualizing it. The experiment turns to 10 000 of E.ON’s customers, having an annual consumption exceeding 10 000 kWh. Customers are equipped with a di
One of the essential engineer’s jobs is to achieve the most economical technical solutions. Weight optimization is important since it provides a structure that can carry the applied loads in addition to fulfilling the structural requirements. In this project, a Matlab-algorithm has been developed to find the optimum design of steel portal frames according to “Eurocode 3: Design of steel structures
The study in this thesis has focused on identifying how the various stakeholders in the rental market perceives and interprets the term of "reasonable housing rent". During the process of this study legislative changes affecting the rental market, is part of the investigation to find out how the stakeholders have reacted to the new reform of the rent laws. Twelve people were interviewe
In 1979 “The Ancient Thebes and its Necropolis” entered in the World Heritage List in a core zone of 7390 ha. Western Thebes holds the remains of about 36 temples in varying degrees of preservation and dating from archaic times (3100 – 2686 B.C.) to the Greco-Roman Period (332 B.C. – 395 A.D.). The temples of Medinet Habu, Ramesseum and Sethos I, are located in the western side of modern Luxor and
This report is a result of a Master Thesis made at Volvo 3P and the Department of Advance Engineering and Concepts. The thesis is a part of the education in Mechanical Engineering at the Department Design Sciences, for the Division of Machine Design at Lund University. Volvo 3P is involved in a project regarding a new patented manufacturing method that is under development. The manufacturing metho
Objective: Interstitial lung disease (ILD) can occur in association with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV-ILD) or as an isolated entity with positive ANCA (ANCA-ILD). However, data on the epidemiology and outcomes of these conditions remain limited. Methods: A European multicenter retrospective study encompassed patients with AAV-ILD or ANCA-ILD. Baseline and s
Bridges are critical assets within transportation networks, and their failure, whether due to accidental actions, extreme environmental events, or localized damage, can lead to consequences that extend far beyond the structure itself. In addition to direct safety implications, bridge failures often result in prolonged traffic disruption, economic losses, and reduced network resilience. As traffic
