Objectives Dietary supplements may ameliorate SARS-CoV-2 infection, although scientific evidence to support such a role is lacking. We investigated whether users of the COVID-19 Symptom Study app who regularly took dietary supplements were less likely to test positive for SARS-CoV-2 infection. Design App-based community survey. Setting 445 850 subscribers of an app that was launched to enable self

OBJECTIVE: Poor metabolic health and unhealthy lifestyle factors have been associated with risk and severity of COVID-19, but data for diet are lacking. We aimed to investigate the association of diet quality with risk and severity of COVID-19 and its interaction with socioeconomic deprivation. DESIGN: We used data from 592 571 participants of the smartphone-based COVID-19 Symptom Study. Diet info

The main focus of this paper is the empirical modelling of the wear of carbon brushes. Rather than determining the dominant wear mechanisms, an approach towards the prediction of wear under a range of different conditions was used. The models were obtained by multiple regression analysis using lifetime (LT) data contributed by the biggest European manufacturer of vacuum cleaner motors. This includ

BACKGROUND: Although gambling disorder is traditionally considered an adult phenomenon, the behavior usually begins in childhood or adolescence.OBJECTIVE: The aim of this study was to explore the frequency of problem gambling among Swedish adolescents and the suspected associated factors.METHODS: This study was based on data collected through a public health survey distributed in 2016 to pupils in

This collection seeks to illustrate the state of the art in territoriological research, both empirical and theoretical. The volume gathers together a series of original, previously unpublished essays exploring the newly emerging territorial formations in culture, politics and society.While the globalisation debate of the 1990s largely pivoted around a ‘general deterritorialisation’ hypothesis, sin

Controllable doping in semiconductor nanowires is essential for development of optoelectronic devices. Despite great progress, a fundamental challenge remains in controlling the uniformity of doping, particularly in the presence of relatively high levels of geometrical inhomogeneity in bottom-up growth. A relatively high doping level of 1E18 cm-3 corresponds to just ~1000 activated dopants in a 2µ

Incorporating rigid cyclic acetal and ketal units into polymer structures is an important strategy towards high-performance materials from renewable resources. In the present work, citric acid, a widely used platform chemical derived from biomass, has been efficiently converted into diand tricyclic diketones. Ketalization with glycerol or trimethylolpropane afforded rigid spirodiols, which were ob

Biografisk artikel om lundastudenten och docenten Hans Henric Hallbäck (1838-1885) med fokus på hans roll som upphovsman till den omstridda "Lincolnvisan" och hur denna kom att prägla hans karriär. Vidare något om visans fortsatta öden.

Historien om den första magisterpromotionen vid Lunds universitet 1670, om de deltagare häri som kunnat identifieras och om hur promotioner generellt gick till under universitetets äldsta tid samt även något kort om den första teologie doktorspromotionen 1672.

Very few countries have managed to decouple economic growth from greenhouse gas emissions in absolute terms and where this was achieved at rates too slow to meet the climate targets of the Paris agreement. To do so, technological solutions would need to be combined with sufficiency-oriented policies in a post growth context. Contributing to such a policy strategy, this paper explores the potential

BACKGROUND: Self-management programs are recognized as a valuable approach to supporting people with long-term conditions, such as stroke, in managing their daily lives. Bridges Self-Management (Bridges) focuses on how practitioners interact and support patients' confidence, skills, and knowledge, and it is an example of a complex intervention. Bridges has been developed and used across multiple h

There is a clear and urgent need to accelerate the implementation of sustainability solutions. We must move beyond simple conceptual understanding of solutions, instead experimenting with collaborators in contexts in order to improve effectiveness, share learnings with others, and avoid future mistakes that waste time.In this episode, we discuss nature-based solutions as a holistic approach addres
