Coupling of dual channel waveform als and sonar for investigation of lake bottoms and shore zones
In this work, we proposed to include remote sensing techniques as a part of the methodology for natural lake bottom mapping, with a focus on the littoral zone. Due to the inaccessibility of this zone caused by dense vegetation, measurements of the lake bottom and the coastline are also difficult to perform using traditional methods. The authors of this paper present, discuss and verify the applica
Mobilizing Scandinavian Children and Youth for the Environment : Launching a Transnational Campaign 1968–1971
In 1968, Swedish insurance company Folksam launched the information campaign Front mot miljöförstöringen (“Front against Environmental Degradation”). The campaign culminated in 1969 with large public hearings where young people addressed local politicians and industry leaders about environmental problems. Throughout this campaign, the aim was to activate youth and make them co-creators of large-sc
Do ectomycorrhizal exploration types reflect mycelial foraging strategies?
Ectomycorrhizal exploration types are commonly assumed to denote spatial foraging patterns and resource-related niches of extraradical mycelia. However, empirical evidence of the consistency of foraging strategies within exploration types is lacking. Here, we analysed ectomycorrhizal foraging patterns by incubating root-excluding ingrowth mesh bags filled with six different substrates in mature Pi
Photoluminescence Polarization of MAPbBr3 Perovskite Nanostructures. Can the Dielectric Contrast Effect Explain It?
The dielectric contrast effect is usually evoked to explain anisotropy of optical properties of elongated nanoobjects, for example, semiconductor nanowires. We applied two-dimensional polarization imaging microscopy to measure the polarization of photoluminescence (PL) excitation and PL intensity of nanoaggregates of in-situ formed MAPbBr3perovskite nanoparticles in a stretched polymeric matrix. S
Role of Hydrophobicity at the N-Terminal Region of Aβ42 in Secondary Nucleation
The self-assembly of the amyloid β 42 (Aβ42) peptide is linked to Alzheimer's disease, and oligomeric intermediates are linked to neuronal cell death during the pathology of the disease. These oligomers are produced prolifically during secondary nucleation, by which the aggregation of monomers is catalyzed on fibril surfaces. Significant progress has been made in understanding the aggregation mech
The use of carvone in consecutive patch testing
Background: Carvone (l-carvone) is a mint-tasting flavour additive that most of us is exposed to and can cause allergic contact reactions. Objectives: To analyse the frequency and the relevance of positive carvone reactions in a dermatitis population. Method: A retrospective analysis of dermatitis patients consecutively tested with carvone from 2017 to 2021. Data were retrieved from the department
Two-peakedness in South Swedish and the Scandinavian tone-accent typology
This chapter presents the results of a production study with twelve speakers of South Swedish. The results show that South Swedish has so-called two-peak contours in non-utterance-final nuclear accents and in phrase-initial accents (so-called initiality accents). The shape of the two-peak contours is reminiscent of contours reported from East Norway and West Sweden. These results contradict previo
Sialyl-Tn Antigen-Imprinted Dual Fluorescent Core-Shell Nanoparticles for Ratiometric Sialyl-Tn Antigen Detection and Dual-Color Labeling of Cancer Cells
Sialyl-Tn (STn or sialyl-Thomsen-nouveau) is a carbohydrate antigen expressed by more than 80% of human carcinomas. We here report a strategy for ratiometric STn detection and dual-color cancer cell labeling, particularly, by molecularly imprinted polymers (MIPs). Imprinting was based on spectroscopic studies of a urea-containing green-fluorescent monomer 1 and STn-Thr-Na (sodium salt of Neu5Acα2-
Using Prosogram to study final rises in South Swedish : Implications for the Scandinavian tone accent typology
This paper presents a production study investigating the frequency of utterance-final rises in South Swedish. These rises are interesting from a dialect typological perspective. Recent findings suggest that South Swedish has two-peak accents utterance medially, whereas previous typologies have assumed only one-peak accents for South Swedish dialects. The South Swedish two-peak accents are similar
Atomic Hydrogen Annealing of Graphene on InAs Surfaces and Nanowires : Interface and Morphology Control for Optoelectronics and Quantum Technologies
Folding two-dimensional graphene around one-dimensional III-V nanowires yields a new class of hybrid nanomaterials combining their excellent complementary properties. However, important for high-quality electrical and optical performance, needed in many applications, are well-controlled oxide-free interfaces and a tight folding morphology. To improve the interface chemistry between the graphene an
A country in focus : Research on foreign language learning, teaching and assessment in Sweden 2012 - 2021
This review provides an account of salient research topics in current Swedish research in the field of foreign language (FL) education, with the aim of making locally published work available outside Sweden. A corpus of work on English and other FLs published between 2012 and 2021 has been scrutinized. Focus has been placed on research conducted and disseminated in Sweden, in some cases adding int
Online and Approximate Network Construction from Bounded Connectivity Constraints
The Network Construction problem, studied by Angluin et al., Hosoda et al., and others, asks for a minimum-cost network satisfying a set of connectivity constraints which specify subsets of the vertices in the network that have to form connected subgraphs. More formally, given a set V of vertices, construction costs for all possible edges between pairs of vertices from V, and a sequence S1,S2,…,Sr
Talk less : The risk of over-communication with seriously ill patients
Common Mode Current Measurements in Traction Systems for Electric Vehicles
The market for partly or fully electrified vehicles is expanding fast. The number of sources and loads that are connected to the vehicles traction voltage systems (TVS) increase and thus also the ElectroMagnetic Compatibility (EMC) requirements on these sources and loads. These requirements should make sure that neither function nor lifetime of any source or load is severely affected by another. T
Substitution of PINK1 Gly411 modulates substrate receptivity and turnover
The ubiquitin (Ub) kinase-ligase pair PINK1-PRKN mediates the degradation of damaged mitochondria by macroautophagy/autophagy (mitophagy). PINK1 surveils mitochondria and upon stress accumulates on the mitochondrial surface where it phosphorylates serine 65 of Ub to activate PRKN and to drive mitochondrial turnover. While loss of either PINK1 or PRKN is genetically linked to Parkinson disease (PD)
Ultrafast laser spectroscopy uncovers mechanisms of light energy conversion in photosynthesis and sustainable energy materials
The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to neodymium-glass lasers produced reasonably well-behaving picosecond pulses. This triggered an intense activity, with respect to developing improved laser pulse sources, measurement techniques, and application to chem
Quantification of [18F]florbetaben amyloid-PET imaging in a mixed memory clinic population : The ABIDE project
Introduction: We investigated amyloid-burden quantification in a mixed memory clinic population. Methods: [18F]Florbetaben amyloid-PET (positron emission tomography) scans of 348 patients were visually read and quantified using the Centiloid (CL) method. General linear models were used to assess CL differences across syndromic and etiological diagnosis. Linear mixed models were fitted to assess th
Toward Biomass-Derived Recyclable Polyesters
Fossil-based plastics have become a matter of concern due to their negative environmental impacts such as greenhouse gas emissions and threats to the health of living beings. Alternative polymers derived from sustainable biomass resources have thus become an attractive research field since the last decade. Currently, there is a strong demand in the development of new bio-based polymers with enhanc
Novel sediment sampling method provides new insights into vertical grain size variability due to marine and aeolian beach processes
In sandy beach systems, the aeolian sediment transport can be governed by the vertical structure of the sediment layers at the bed surface. Here, data collected with a newly developed sand scraper is presented to determine high-resolution vertical grain size variability and how it is affected by marine and aeolian processes. Sediment samples at up to 2 mm vertical resolution down to 50 mm depth we
