Recognition of drilling-induced defects in Fiber Reinforced Polymers using Machine Learning

The machining of Fiber Reinforced Polymers (FRP) is accompanied by specific defects such as delamination, uncut fibers, and others. Such defects are unique in their shape and size for different FRP types, used tools, and applied cutting conditions. Therefore, defect recognition and quantification remain a central challenge in the quality control of FRP components from an accuracy and time balance

Finite Element Modelling of Fluid-Structure Interaction

The dynamic interaction between a non-viscid, compressible fluid and an elastic structure is studied. Finite element formulations, using the weighted residual method, are derived. Different primary variables in the fluid domain are used and different source functions are considered.When a potential field is used, the dynamic interaction between fluid and structure yields nonsymmetric matrices.

Beware Europe’s New Green Colonialism

Europe is leading the world in cutting carbon emissions. By 2020, the European Union had reduced emissions by an estimated 34 percent compared to 1990 levels, which puts its promised 55 percent reduction by 2030 safely within reach. By comparison, the United States has managed only a 7 percent reduction over the same period.However, this European success story comes with a big asterisk. The EU has

Lipid-associated macrophages transition to an inflammatory state in human atherosclerosis, increasing the risk of cerebrovascular complications

The immune system is integral to cardiovascular health and disease. Targeting inflammation ameliorates adverse cardiovascular outcomes. Atherosclerosis, a major underlying cause of cardiovascular disease, is conceptualized as lipid-driven inflammation in which macrophages play a nonredundant role. However, evidence emerging so far from single-cell atlases suggests a dichotomy between lipid-associa

Maternal separation differentially modulates early pathology by sex in 5xFAD Alzheimer’s disease-transgenic mice

Alzheimer’s disease (AD) is the most common neurodegenerative disease. Most cases of AD are considered idiopathic and likely due to a combination of genetic, environmental, and lifestyle-related risk factors. Despite occurring decades before the typical age of an AD diagnosis, early-life stress (ELS) has been suggested to have long-lasting effects that may contribute to AD risk and pathogenesis. S

The EAT-Lancet diet, genetic susceptibility and risk of atrial fibrillation in a population-based cohort

BACKGROUND: The EAT-Lancet Commission proposed a global reference diet with both human health benefits and environmental sustainability in 2019. However, evidence regarding the association of such a diet with the risk of atrial fibrillation (AF) is lacking. In addition, whether the genetic risk of AF can modify the effect of diet on AF remains unclear. This study aimed to assess the association of

Bakom kulisserna i Edens lustgård : Antika fiendebilder och behovet av den Andre

I mötet med människor som avviker från normen sker något viktigt med oss. Det ärmycket tack vare »den Andre« de som inte är som vi som vi får reda på vilka vi egentligen är.I västerlandet har kristendomen varit norm i tusen år, och det var under kristendomenstidiga historia som många av vår kulturs traditionella fiendebilder föddes. De har spelat en viktig roll för framväxten av vårt moderna samhä

Regulation and Mitigation of Greenhouse Gases

While most greenhouse gases are not toxic and no pollutants, their increasing concentration in the atmosphere is enhancing the greenhouse effect and causing climate change. Climate change however is a massive threat to all global life-sustaining systems, and it will among other highly damaging consequences probably also create significant health problems. This chapter first explains the natural sc

Cognitive decline and risk of dementia in older adults after diagnosis of chronic obstructive pulmonary disease

Cognitive screening has been proposed for older adults diagnosed with chronic obstructive pulmonary disease (COPD). Therefore, we examined the change over time in cognitive function and the risk of incident dementia in older adults after COPD diagnosis. A sample of 3,982 participants from the population-based cohort study Good Aging in Skåne was followed for 19 years, and 317 incident COPD cases w

Glyptothorax vatandousti, a new species of torrent catfish from the upper Karkheh drainage in Iran (Teleostei: Sisoridae)

Glyptothorax vatandousti, new species, from the upper Karkheh drainage, a tributary of the Iranian Tigris, is distinguished from its congeners in the Persian Gulf basin by having the flank with a fine, pale-brown mottled pattern overlaid by small and large, blackish or dark-brown blotches, deep caudal-peduncle (its depth 1.1–1.3 times in length), and without, or with a pale-brown triangle-shaped b

A pilot study of an organised population‐based testing programme for prostate cancer

ObjectiveTo determine the feasibility of a digitally automated population-based programme for organised prostate cancer testing (OPT) in Southern Sweden.Patients and MethodsA pilot project for a regional OPT was conducted between September 2020 and February 2021, inviting 999 randomly selected men aged 50, 56, or 62 years (y). Risk stratification was based on PSA, PSA density (PSAD), and biparamet

Fast-track Sociology? Reflections on Research During a Pandemic

When the coronavirus spread globally in early 2020, many governments issued national lock downs of schools, institutions, and businesses. As the epidemic turned into a pandemic, the health crisis also became a societal crisis, and many universities and research foundations issued COVID-19 grants to study the societal implications of the crisis. In this article, we discuss sociological research dur

Tinkering with malleable grassroots infrastructures : Kenyan local currencies in informal settlements

The article examines how dwellers in Kenya’s informal settlements engage in continuous tinkering of a particular grassroots infrastructure: local currencies. The article argues that the malleability of these grassroots infrastructures enables grassroots networks to actively and creatively engage in reclaiming and reorganizing money, a critical infrastructure. The argument is built in three steps.

Circular Economy in the Nordic Real Estate and Construction Industry: A Policy Review

Circular economy (CE) has gained attention in the real estate and construction policy, practice, and research in the past few years. This study explores how two neighboring Nordic countries and EU member states, Sweden and Finland, are transitioning toward circularity in the real estate and construction industry context. The aim is reached through a review of CE policies on the national and indust

Improved identification of Streptococcus bovis-Streptococcus equinus-complex species and subspecies by MALDI-TOF MS using a novel library

ObjectivesTo develop an in-house matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) library for improved identification of species and subspecies of the Streptococcus bovis/Streptococcus equinus-complex (SBSEC).Methods236 SBSEC isolates from blood stream infections and culture collections, determined by whole genome sequencing to subspecies level, were grow

Isolation and Purification of Mycobacterial Extracellular Vesicles

Bacterial extracellular vesicles (EVs) contain numerous active substances that mediate bacterial interactions with their host and with other microbes. Best defined are the EVs from Gram-negative bacteria that have been shown to deliver virulence factors, modulate the immune responses, mediate antibiotic resistance, and also inhibit competitive microbes. Due to the complex cell wall structures of G

Raptor vision

Diurnal raptors (birds of the orders Accipitriformes and Falconiformes), renowned for their extraordinarily sharp eyesight, have fascinated humans for centuries. The high visual acuity in some raptor species is possible due to their large eyes, both in relative and absolute terms, and a high density of cone photoreceptors. Some large raptors, such as wedge-tailed eagles and the Old World vultures,

Genome-wide association meta-analyses and fine-mapping elucidate pathways influencing albuminuria

Increased levels of the urinary albumin-to-creatinine ratio (UACR) are associated with higher risk of kidney disease progression and cardiovascular events, but underlying mechanisms are incompletely understood. Here, we conduct trans-ethnic (n = 564,257) and European-ancestry specific meta-analyses of genome-wide association studies of UACR, including ancestry- and diabetes-specific analyses, and

Effects of lactobacillus plantarum and lactobacillus paracasei on the peripheral immune response in children with celiac disease autoimmunity : A randomized, double-blind, placebo-controlled clinical trial

Two Lactobacillus strains have proven anti-inflammatory properties by reducing pro-inflammatory responses to antigens. This randomized double-blind placebo-controlled trial tested the hypothesis that L. plantarum HEAL9 and L. paracasei 8700:2 suppress ongoing celiac disease autoimmunity in genetically at risk children on a gluten-containing diet in a longitudinally screening study for celiac disea
