In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u
Although the UN concluded, already in 1997, that water would be the most contentious issue of the 21st century, water governance is still confused, nearly everywhere. Even the severe impacts of escalating water bankruptcy and global warming have so far failed to incur a marked improvement in governance systems. The global community has adopted sustainable development as a common vision and guide f
Perovskite light-emitting diodes (PeLEDs) have recently shown significant progress with external quantum efficiencies (EQEs) exceeding 20%. However, PeLEDs with pure-red (620−660 nm) light emission, an essential part for full-color displays, remain a great challenge. Herein, a general approach of spacer cation alloying is employed in Ruddlesden–Popper perovskites (RPPs) for efficient red PeLEDs wi
With the advent of nationwide mammography screening programmes, a number of natural history models of breast cancers have been developed and used to assess the effects of screening. The first half of this article provides an overview of a class of these models and describes how they can be used to study latent processes of tumour progression from observational data. The second half of the article
Lunds kommun äger LKF, Lunds Kommuns Fastighets AB. LKF i sin tur äger och förvaltar ett stort fastighetskapital. Marknadsvärdet uppskattas till omkring 16 000 miljoner kronor för närvarande. En central fråga infinner sig: förvaltas detta kapital på ett effektivt sätt? Ger den nuvarande förvaltningen en gynnsam avkastning åt medborgarna i Lunds kommun? För att finna ett svar på denna fråga har Lun
The value-belief-norm (VBN) theory has been widely used to describe pro-sustainability behavior. Despite being used to examine issues of sustainable and public transport behavior, research using the VBN has largely overlooked the pro-environmental behavior of cyclists and walkers, which is extremely significant given the role of active transport in environmental and human health. Therefore, this s
Objectives: To investigate factors associated with multiple induced abortions. Materials and methods: A multi-centre cross-sectional survey among abortion-seeking women (n = 623;14-47y) in Sweden, 2021. ‘Multiple abortions’ was defined as having had ≥2 induced abortions. This group was compared to women with a previous experience of 0-1 induced abortion. Regression analysis was conducted to determ
The pathophysiological mechanisms intersecting metabolic and neurodegenerative disorders include insulin resistance, which has a strong involvement of environmental factors. Besides central regulation of whole-body homeostasis, insulin in the central nervous system controls molecular signalling that is critical for cognitive performance, namely signalling through pathways that modulate synaptic tr
Background: Coarctation of the aorta (CoA), a congenital narrowing of the proximal descending thoracic aorta, is a relatively common form of congenital heart disease. Untreated significant CoA has a major impact on morbidity and mortality. In the past 3 decades, transcatheter intervention (TCI) for CoA has evolved as an alternative to surgery. Objectives: The authors report on all TCIs for CoA per
Aims/hypothesis: Individuals with diabetes can be clustered into five subtypes using up to six routinely measured clinical variables. We hypothesised that circulating protein levels might be used to distinguish between these subtypes. We recently used five of these six variables to categorise 7017 participants from the Outcome Reduction with an Initial Glargine Intervention (ORIGIN) trial into the
Biomolecules preserved in deep time have potential to shed light on major evolutionary questions, driving the search for new and more rigorous methods to detect them. Despite the increasing body of evidence from a wide variety of new, high resolution/high sensitivity analytical techniques, this research is commonly met with skepticism, as the long standing dogma persists that such preservation in
The meshless radial point interpolation method (RPIM) in frequency domain for electromagnetic scattering problems is presented. This method promises high accuracy in a simple collocation approach using radial basis functions. The treatment of high-order non-reflecting boundary conditions for open waveguides is discussed and implemented up to fourth-order. RPIM allows the direct calculation of high
Background: Microbial production of propionic acid (PA) from renewable resources is limited by the slow growth of the producer bacteria and product-mediated inhibition. The present study evaluates high cell density continuous PA fermentation from glycerol (Gly) using Acidipropionibacterium acidipropionici DSM 4900 in a membrane-based cell recycling system. A ceramic tubular membrane filter of 0.22
Jordbruket är en av de sektorer i samhället som har störst klimatpåverkan genom utsläppet av växthusgaser och användningen av mark. Samtidigt är jordbruket den huvudsakliga källan till utsläppet av ammoniak i Sverige. Ammoniak kan i sin tur bilda hälsovådliga partiklar. Att minska klimatpåverkan och luftutsläpp kan därför vara av stor betydelse för att nå uppsatta miljömål. Till skillnad från andr
We train and compare the performance of two different machine learning algorithms to learn changes in winter wheat production for fields from the southwest of Sweden. As input to these algorithms, we use cloud-penetrating Sentinel-1 polarimetry radar data together with respective field topography and local weather over four different years. We note that all of the input data were freely available.
PURPOSE: To investigate factors related to omitted total body skin examination (TBSE) in skin cancer diagnostics while managing patients using teledermoscopy (TDS) in Swedish primary care.METHODS: 4,987 TDS referrals from primary care centers were analyzed to identify factors associated with failing to perform TBSE. Data collected included age, gender of patient and physician, and reason for a vis
Concerns about fairness among countries remain significant obstacles to a stronger global climate treaty. This paper addresses the distributional implications of two mechanisms to strengthen the Paris Agreement, the incorporation of national carbon pricing, and the tightening of nationally determined contributions (NDCs). Both are found to be viable mechanisms. They are also less extreme, and ther
