This study explores the effectiveness of combining Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) for identifying internal erosion processes in embankment dams. A small-scale test dam was built in Älvkarleby, Sweden, with deliberately embedded but undisclosed defects to test monitoring capabilities. Daily ERT and IP measurements were collected during 4.5-year years, and anal
The sheet metal forming process is integral to the automotive industry, producing a variety of components essential for vehicle construction, including body panels, chassis parts, and structural supports. The process involves shaping thin metal sheets into desired forms using techniques such as bending, stretching, drawing, and stamping. In order to build high quality cars it is vital with an effi
Despite available training in food safety, regular inspections from the authorities and strict laws and regulations, the number of suspected food poisoning is estimated at 500,000 cases per year in Sweden (Norling, 1994). Since the 1990s, there have been discussions about introducing a "mandatory food driver's license" to improve food safety in Sweden. But no such license exists toda
The modern food industry faces the challenge of catering to diverse consumer preferences while maintaining efficiency and profitability. Rapid shifts in consumer trends, emerging technologies, and evolving regulations make it difficult for companies to keep pace, often resulting in inefficiencies and lost opportunities. The vast amount of data generated across production, supply chains, and marke
Cemented carbides with tungsten carbide grains as hard phase and metallic cobalt binder phase are used extensively for drill bit inserts for rock drilling. The process of rock drilling is severe with some of the wear happening through fracture in the cemented carbide. This work investigated two cemented carbides with iron rich alternative binder phases containing different amounts of FCC phase, in
This paper aims to empirically explore and conceptualise how circular fashion platforms enable and shape the practice of secondhand clothes shopping. Taking a shopping-as-practice approach and drawing on an ethnographically inspired study, this paper explores how a Swedish digital second-hand commerce platform enables different modes of shopping. The analysis shows that this platform and its socio
Aerosolised Polystyrene Latex (PSL) nanoparticles are, due to their well-defined size, spherical shape, and inert surface, useful in many experimental applications, including studies of particle deposition in the human lung. Aerosolising nanoparticles entails added challenges, and nanoparticles can potentially be more hazardous than otherwise equivalent microparticles. The objective of this work w
We report on the experimental investigation of potential high-performance cavity length stabilization using odd-indexed higher-order spatial modes. Schemes based on higher-order modes are particularly useful for micro-cavities that are used for enhanced fluorescence detection of a few emitters, which need to minimize photons leaking from a stabilization beam. We describe the design and constructio
Aim: Assess effects on waist circumference from diet with or without cereal grains and with or without long-term physical exercise. Background: Elevated waist circumference is an indicator of increased abdominal fat storage and is accordingly associated with increased cardiovascular mortality. This is likely due to the association between lifestyle-induced changes in waist circumference and cardio
This article discusses how fiction and its collisions between different linguistic registers have both literary and pedagogical potential. Taking its point of departure in literary texts used in the medical humanities teaching at the medical school at Lund University, various types of collisions between literary language and medical language are analysed. To conceptualize the collisions between th
A high spatiotemporal resolution technique for instantaneous flow field measurement has been developed, enabling one-dimensional velocimetry and flow field visualization within a converging–diverging nozzle. By employing femtosecond laser-induced long-lived, high-intensity plasma emission in a CO2/N2 gas flow, coupled with an ICCD camera, we achieved instantaneous one-dimensional velocity measurem
InAs nanowires have been used as selectors and electrodes in a one-transistor one-resistor resistive random-access memory (RRAM) configuration for increased memory scalability. Such oxide-based memories not only show promise both in conventional memory technology but also as analog memories for neural networks. The small areas of the oxide elements, however, result in challenges for electrical cha
It is well known that Lithium-ion batteries in thermal runaway can emit gases with high hydrogen concentrations which, in case of delayed ignition, can cause a gas explosion. Aerosol suppression agents are sometimes used to suppress fires and/or prevent ignition of released gases in such situations. The agent has been studied for suppression of fires (diffusion flames), but less is known about the
Bacterial infection and hemorrhage remain significant clinical challenges for chronic wounds, despite advancements in antimicrobial strategies and materials. Herein, 980 nm-laser-responsive photothermal conjugated polymers (CPs) are combined with chitosan-based cryogels (CP@Gel) to achieve rapid hemostasis and efficient anti-infectious performance. CP nanoparticles (CP NPs) were prepared by nanopr
NaOH and NaCl vapor are key alkali compounds released during the thermal conversion of high-alkali coal and municipal solid waste, and their accurate measurement is crucial for understanding the mechanisms of ash deposition, slagging, and other related issues. However, in-situ and species-specific measurement techniques with high sensitivity for NaOH and NaCl molecules in hash combustion environme
The 2017 Global Award for Entrepreneurship Research is given to Hernando de Soto, president of the Institute for Liberty and Democracy (ILD) in Lima, Peru. Over the last 30 years, Hernando de Soto has been a world-leading intellectual engaged in academic and public policy discussions on global development. He has made substantial contributions to our understanding of the informal economy and of th
This paper reports simultaneous detection of ultra violet (UV) absorbance and native UV-excited fluorescence in an electrophoresis microchip using UV transparent integrated waveguides. Absorbance detection enables detection of a wide range of analytes. When exposed to UV light, some compounds also exhibit native fluorescence, which is here detected simultaneously. Calibration curves were measured
The ability to apply highly controlled electric fields within microfluidic devices is valuable as a basis for preparative and analytical processes. A challenge encountered in the context of such approaches in conductive media, including aqueous buffers, is the generation of electrolysis products at the electrode/liquid interface which can lead to contamination, perturb fluid flows and generally in
