The Central Iapetus magmatic province : An updated review and link with the ca. 580 Ma Gaskiers glaciation

Large igneous provinces and associated silicic magmatism can have a significant global climatic effect, so we explored the relationship between the large igneous province record and the ca. 580 Ma Gaskiers glaciation. The late Ediacaran glaciation exists on at least 14 different paleocontinental blocks, and assuming synchroneity, this Gaskiers glaciation was likely of short duration, with estimate

Mono endo-6- And bis endo,endo-12-N,N-diethylcarbamoyl derivatives of Tröger’s Base. Synthesis and exo-endo isomerization study

An efficient synthetic route to the mono-endo-6- and bis-endo,endo-6,12-N,N-diethylcarbamoyl derivatives of Tröger’s base (TB), endo-7 and endo-8, is reported. Studies of reaction time, proton source, and additive allowed establishment of optimized conditions for the conversion of exo-7 into the corresponding isomer endo-7. With a longer reaction time, the exo,exo-6,12 bis-carbamoyl derivative exo

Quinoline-triazole half-sandwich iridium(iii) complexes : Synthesis, antiplasmodial activity and preliminary transfer hydrogenation studies

Iridium(iii) half-sandwich complexes containing 7-chloroquinoline-1,2,3-triazole hybrid ligands were synthesised and their inhibitory activities evaluated against the Plasmodium falciparum malaria parasite. Supporting computational analysis revealed that metal coordination to the quinoline nitrogen occurs first, forming a kinetic product that, upon heating over time, forms a more stable cyclometal

Iterative metal artifact reduction in aortic CTA after Onyx®-embolization

Purpose: Onyx® embolization causes severe artifacts on subsequent CT-examinations, thereby seriously limiting the diagnostic quality. The purpose of this work was to compare the diagnostic quality of the tailored metal artifact reducing algorithms iMAR to standard reconstructions of CTA in patients treated with Onyx® embolization. Method: Twelve consecutive patients examined with Dual Energy CTA a

Identifying normal mammograms in a large screening population using artificial intelligence

Objectives: To evaluate the potential of artificial intelligence (AI) to identify normal mammograms in a screening population. Methods: In this retrospective study, 9581 double-read mammography screening exams including 68 screen-detected cancers and 187 false positives, a subcohort of the prospective population-based Malmö Breast Tomosynthesis Screening Trial, were analysed with a deep learning–b

Working Poor? A Study of Rural Workers' Economic Welfare in Kenya

This study employs a mixed methods approach to investigate the poverty reduction potential of large‐scale farm employment in Kenya. A long‐run time series of real agricultural wages is created. The quantitative data are supplemented by life‐story interviews of agricultural workers. The analysis suggests that large‐scale farm employment can serve as a route out of deep poverty. However, to prevent

Antimicrobial resistance (AMR) has come to prominence as a priority for policy makers and healthcare professionals. There are many well-described guidelines on how healthcare professionals should handle AMR. However, professional practices are sometimes different from what the guidelines prescribe.

Politics and the plastic crisis: A review throughout the plastic life cycle

This article surveys the politics of plastics through a reading and analysis of more than 180 scientific articles in the fields of environmental science and environmental studies. Despite the many benefits of plastics, the global plastic system is increasingly being recognized as the source of severe environmental problems. Rather than orient the investigation around specific venues, levels, or ar

Ozonation of Sitagliptin : Removal Kinetics and Elucidation of Oxidative Transformation Products

Due to the increasing use and high excretion rates, high quantities of the antidiabetic drug sitagliptin (STG) enter wastewater treatment plants (WWTPs). In conventional biological treatment, only a moderate removal was achieved, and thus, STG can be detected in WWTP effluents with concentrations in the higher ng/L range. Ozonation is a widely discussed technique for advanced wastewater treatment.

Parents’ reported experiences when having a child with cataract—important aspects of self-management obtained from the paediatric cataract register (PECARE)

Parents are a crucial part in the care of children with pediatric cataract. The aim of this study was to explore and explain sense of coherence, family self-efficacy, perceived social support, fatigue and parent reported experiences (PREM), in order to improve clinical care. Questionnaires were sent to the parents of children registered in the Swedish national Paediatric Cataract Register, PECARE,

Transformative education : towards a relational, justice-oriented approach to sustainability

Purpose: This paper aims to increase related knowledge across personal, social and ecological dimensions of sustainability and how it can be applied to support transformative learning. Design/methodology/approach: The paper provides a reflexive case study of the design, content and impact of a course on eco-justice that integrates relational learning with an equity and justice lens. The reflexive

The Spanish version of the mothers' postnatal sense of security scale : Psychometric properties and predictive utility

Postnatal sense of security is a relevant construct related to several variables of motherhood. However, it has not yet been studied in the Spanish context. The aims were: (a) To analyze the psychometric properties of a Spanish version of the mothers' postnatal sense of security scale (PPSS-S); (b) analyze the factors related to mothers' sense of security during the first 2 weeks following childbi

Treatment and prognosis of patients with urinary bladder cancer with other primary cancers : a nationwide population-based study in the Bladder Cancer Data Base Sweden (BladderBaSe)

Objective: To study how patients with urinary bladder cancer (UBC) with previous or concomitant other primary cancers (OPCs) were treated, and to investigate their prognosis. Patients And Methods: Using nationwide population-based data in the Bladder Cancer Data Base Sweden (BladderBaSe), we analysed the probability of treatment with curative intent, and UBC-specific and overall survival (OS) in p

A fingerprint of climate change across pine forests of Sweden

Climate change has likely altered high-latitude forests globally, but direct evidence remains rare. Here we show that throughout a ≈1000-km transect in Scots pine (Pinus sylvestris L.) forests in Sweden, mature trees in ≈2015 had longer needles with shorter lifetimes than did trees in ≈1915. These century-scale shifts in needle traits were detected by sampling needles at 74 sites from 2012 to 2017

Multilinear singular integrals on non-commutative Lp spaces

We prove Lp bounds for the extensions of standard multilinear Calderón–Zygmund operators to tuples of UMD spaces tied by a natural product structure. The product can, for instance, mean the pointwise product in UMD function lattices, or the composition of operators in the Schatten-von Neumann subclass of the algebra of bounded operators on a Hilbert space. We do not require additional assumptions

Devising food consumption : complex households and the socio-material work of meal box schemes

The aim of this paper is to explore how digitally-enabled food provisioning platforms reconfigure households’ food consumption. Taking a market studies approach, and drawing on an ethnographic study of 15 households signing up to meal box schemes, the paper examines how meal box schemes, as market devices, work towards materially-semiotically organising household food consumption. Analysis shows t
