Reclassification of bridges, i.e., a change in load rating, using reliability-based methods and a direct update with proof load information has been presented by many authors. However, bridge reclassification has hardly been studied from a decision analytic perspective, i.e., with quantification of the risks and benefits of different classification choices, and the expected benefit gain from proof

Microplastics provide a new ecological niche for microorganisms, and the accumulation levels of microplastics (MPs) in terrestrial ecosystems are higher than those in marine ecosystems. Here, we applied the zymography to investigate how MPs — polyethylene [PE], and polyvinyl chloride [PVC]) at two levels (0.01% and 1% soil weight) impacted the spatial distribution of soil hydrolases, nutrient avai

PURPOSE: To evaluate the outcomes of preserving the internal iliac artery (IIA) with iliac branched devices (IBDs) during acute endovascular repair of ruptured aortoiliac aneurysms.MATERIAL AND METHODS: This is a multicenter retrospective review of all consecutive patients undergoing acute endovascular repair of ruptured aortoiliac aneurysm with an IBD at 8 aortic centers between December 2012 and

Under början av 1700-talet förändrades Göteborg. Stadens invånare, tomter och bebyggelse kom i allt större utsträckning att bevaras inom en tidigmodern struktur. Göteborg 1713 – en visuell mikrohistoria är en bok som handlar om stadens invånare och deras möjligheter att själva definiera sin omgivning under århundradets inledande decennier. Staden i boken är en plats i förändring som i skuggan av s

Objectives: Estimations of glomerular filtration rate (eGFR) are based on analyses of creatinine and cystatin C, respectively. Coronavirus disease 2019 (COVID-19) patients in the intensive care unit (ICU) often have acute kidney injury (AKI) and are at increased risk of drug-induced kidney injury. The aim of this study was to compare creatinine-based eGFR equations to cystatin C-based eGFR in ICU

To quickly identify maritime sites polluted by heavy metal contaminants, reductions in the size of instrumentation have made it possible to bring an X-ray fluorescence (XRF) analyzer into the field and in direct contact with various samples. The choice of source-sample-detector geometry plays an important role in minimizing the Compton scattering noise and achieving a better signal-to-noise ratio

East Asian societies, which have been under the influence of Confucian ethics, underwent profound and diverse socioeconomic transformations after the Second World War such as rapid economic growth, socialist reforms, and renewed engagement with global neoliberalism. These changes have led to major shifts in the roles and functions of the family, as witnessed in demographic patterns such as ultra-l

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

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

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

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

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

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
