The performance of a new type of X-band Weather Radar (WR) for Sweden during a pilot run is studied. Compared to the conventional C-band WRs, the X-band WR covers a smaller area but with a higher spatiotemporal resolution, making it suitable for urban hydrological applications. Rainfall estimations from different elevation angles of the radar (levels) are compared at one-minute and single-event ti
The presence of paralytic shellfish poisoning toxins (PSTs) in drinking water resources has urged the development of simple and fast screening tools for drinking water surveillance. This article aims to validatea quick test kit for freshwater PSTs detection. Preliminary estimates of the limit of detection (LODs)were done for 5 PSPs variants, namely C1 toxin (a “C” toxin); GTX5(a Gonyautoxin); and
GaN nanowires are potential candidates for use in scanning probe microscopy due to their well-defined, reproducible, geometric shapes, their hardness, and their light guiding properties. We have developed and investigated probes for high resolution atomic force microscopy and scanning tunneling microscopy utilizing GaN nanowires as probes. The nanowires are n-doped and the morphology of the nanowi
We have developed an electrochemical cell for in situ 2-Dimensional Surface Optical Reflectance (2D-SOR) studies during anodization and cyclic voltammetry. The 2D-SOR signal was recorded from electrodes made of polycrystalline Al, Au(111), and Pt(100) single crystals. The changes can be followed at a video rate acquisition frequency of 200 Hz and demonstrate a strong contrast between oxidizing and
The nucleation of Alzheimer-associated Aβ peptide monomers can be catalyzed by preexisting Aβ fibrils. This leads to autocatalytic amplification of aggregate mass and underlies self-replication and generation of toxic oligomers associated with several neurodegenerative diseases. However, the nature of the interactions between the monomeric species and the fibrils during this key process, and indee
Energy dispersive x-ray spectroscopy in a transmission electron microscope is often the first method employed to characterize the composition of nanowires. Ideally, it should be accurate and sensitive down to fractions of an atomic percent, and quantification results are often reported as such. However, one can often get substantial errors in accuracy even though the precision is high: for nanowir
Fluid transport in the perivascular space by the glia-lymphatic (glymphatic) system is important for the removal of solutes from the brain parenchyma, including peptides such as amyloid-beta which are implicated in the pathogenesis of Alzheimer’s disease. The glymphatic system is highly active in the sleep state and under the influence of certain of anaesthetics, while it is suppressed in the awak
How genome-wide association studies-identified single-nucleotide polymorphisms (SNPs) affect remote genes remains unknown. Expression quantitative trait locus (eQTL) association meta-analysis on 496 prostate tumor and 602 normal prostate samples with 117 SNPs revealed novel cis-eQTLs and trans-eQTLs. Mediation testing and colocalization analysis demonstrate that MSMB is a cis-acting mediator for S
Abstract: Ceramic matrix composites based on cubic boron nitride with a TaC binder phase are sintered under conditions of high pressure and high temperature. The sintering is carried out in a high-pressure apparatus of the toroid type in the temperature range of 1450–2450°C. It is shown that a chemical reaction between components of the mixture with the formation of TaB2 takes place at a sintering
Investigations of social-genetic effects, whereby a social partner’s genotype affects another’s outcomes, can be confounded by the influence of the social partner’s rearing environment. We used marital information on more than 300,000 couples from Swedish national data to disentangle social-genetic from rearing-environment effects for alcohol use disorder (AUD). Using observational and extended-fa
The transition to a resource efficient economy that makes effective use of raw materials and energy is a multi-level dynamic process requiring a wide systems perspective. To operationalize this transition in a holistic manner, the concept of Circular Economy (CE) has been championed by major economies around the world. The idea with CE is to strive towards maximizing the utilization of products, c
Many parents perceive the urban environment as hazardous for their children and therefore prescribe and circumscribe young people’s access to the environment (Malone, 2001). Consequently, spontaneous unregulated play in neighbourhood spaces is decreasing as children are primarily encouraged to participate in regulated play environments in their homes, friends houses and commercial facilities. Simu
Throughout this thesis, samples of various materials with applications in energy converting devices have been prepared by focused ion beam machining and investigated by transmission electron microscopy. Energy converting devices can be solar cells or light emitting diodes, which turn light into electricity or vice versa. They can also be fuel cells or electrolyzer cells, which turn chemical energy
Market-based instruments have become a widely used approach to motivate landowners to conserve forests instead of clearing them. However, such market-based instruments are increasingly criticized for their simplistic view on complex environmental, social and economic issues; for their ethical stance; and for creating exchange value for essential ecosystems services, which potentially perpetuates a
Popular Abstract in English Look around and notice how many items have been manufactured or transported using petroleum-based products. In modern life, it is almost an impossible task to exclude them from our daily routine. They are present in plastics, cosmetics, cleaning products, medicaments, food, etc. To diminish our dependence on the demanded black liquid, a lot of research efforts have beenDepletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. Efficient processes for the conversion of pla
BackgroundPatients with advanced ovarian cancer (AOC) who undergo primary and interval debulking surgery are often anemic at diagnosis, with iron deficiency being the most common cause. The aim was to investigate whether preoperative anemia and iron deficiency impact short-term recovery.MethodsThis retrospective cohort study included 262 patients with AOC who underwent surgery at Skane University
Micro-LEDs have emerged as a hot research topic due to their potential for next-generation display and lighting applications, necessitating advanced characterization techniques to optimize their performance. This study demonstrates the advantage of cathodoluminescence in the scanning electron microscope to be a critical tool for the optical characterization of InGaN platelets with red quantum well
