Transition from Boundary-Driven to Bulk-Driven Acoustic Streaming Due to Nonlinear Thermoviscous Effects at High Acoustic Energy Densities
Acoustic streaming at high acoustic energy densities Eac is studied in a microfluidic channel. It is demonstrated theoretically, numerically, and experimentally with good agreement that frictional heating can alter the streaming pattern qualitatively at high Eac above 400 J/m^3. The study shows how as a function of increasing Eac at fixed frequency, the traditional boundary-driven four streaming r
Using an ionomer as a size regulator in γ-radiation induced synthesis of Ag nanocatalysts for oxygen reduction reaction in alkaline solution
Ag nanoparticles (Ag NPs) are among the most promising candidates to replace Pt as the catalyst for the oxygen reduction reaction (ORR) in anion exchange membrane fuel cells (AEMFCs). However, synthesizing size-controlled Ag NPs with efficient catalytic performance is still challenging. Herein, uniform Ag NPs are produced through a γ-radiation induced synthesis route in aqueous solutions, using th
Consumption of ultraprocessed food and development of chronic kidney disease : the Tianjin Chronic Low-Grade Systemic Inflammation and Health and UK Biobank Cohort Studies
BackgroundMany ultraprocessed food (UPF)-derived by-products may play a role in the development of chronic kidney disease (CKD). Although several studies have assessed the association of UPFs with kidney function decline or CKD in various countries, no evidence has been shown in China and the United Kingdom.ObjectivesThis study aims to evaluate the association between UPF consumption and risk of C

Finance for Fossils – the Role of Public Financing in Expanding Petrochemicals
The petrochemicals industry (mainly plastics and fertilizer production) is expanding, despite increasing attention to the environmental impact of petrochemicals. In our paper, we explore the role public finance plays in the petrochemicals industry. We do so by mapping the public and private financial flows into large-scale petrochemical projects for the decade 2010-20 and discuss the role of publi

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
