Reducing scrapping of gears by assessment of tip contact threshold torque

While striving for more competitive products as well as reaching the Global Sustainable Development Goals, automotive powertrain manufacturers increase the demands on gears, which translates to decreased manufacturing error tolerances. Too tight tolerances may, however, counteract the goal if it leads to increased material and energy consumption due to unjustified scrapping. This paper presents a

Stolar och bänkar : En sittmöbelstudie i Lunds stifts gudstjänstrum

Det pågår förändringar i våra kyrkor. Krav och behov på användande av gudstjänstrum leder till ändringar och ibland omfattande omgestaltningar. Föreliggande rapport är ett resultat av en studie som fokuserar påförändringsprocesser kopplade till sittmöbler i Svenska kyrkan, närmare bestämt bänkar och stolar avsedda för församlingen. Våra exempel är hämtade från nyligen genomförda eller pågående sit

Terminal T-wave inversion predicts reperfusion tachyarrhythmias in STEMI

INTRODUCTION: A reliable electrocardiographic predictor of ventricular fibrillation (VF) in patients with ST elevation myocardial infarction (STEMI) is lacking so far. Previous experimental/simulation study suggested a terminal T-wave inversion (TTWI) in ischemia-related ECG leads corresponding to anterior infarct localization as an independent predictor of reperfusion VF (rVF). This T-wave charac

Auraproduktion och "klassikerfiering" : Om aktivt meningsskapande som gör möbler till klassiker ‒ exemplifierat genom stolar från Sverige och Danmark

Klassiker är ett komplext fenomen. Dynamiskt och svårfångat. Artikeln undersöker hur en modern möbelklassiker skapas Begreppet kan laddas med värden av både immateriell och materiell karaktär. Auraproduktion fyller möbeln med innehåll och stärker den som objekt, vilket gör det till ett operativt och flitigt använt epitet inom både kommersiell och kulturell verksamhet. I artikeln lyfts exempel på p

Droplet, aerosol and SARS-CoV-2 emissions during singing and talking

IntroductionAs the pandemic continues to spread, more knowledge is needed about the viral transmission routes. Several super spreading events during the Covid-19 pandemic have been linked to singing in choirs and talking loud. However, in the beginning of the pandemic there was only one study about emitted aerosols and droplets from singing, published in 1968, and only a handful on emissions from

SARS-CoV-2 in aerosol particles exhaled from COVID-19 infected patients during breathing, talking and singing

In the beginning of the COVID-19 pandemic, several super spreader events occurred during choir singing, which lead to an increased attention to airborne transmission of SARS-CoV-2. Since then, aerosol generation from singing has been studied in detail, however, mainly from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 38 COVID-19 infected patients during

SARS-CoV-2 in aerosol particles exhaled from COVID-19 infected patients during breathing, talking and singing

In the beginning of the COVID-19 pandemic, several super spreader events occurred during singing in choirs, which lead to an increased attention to airborne transmission of SARS-CoV-2, the virus causing COVID-19. Since then, aerosol generation from singing has been studied in more detail, however, only from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 40

Collaborative Aspects of Open Data in Software Engineering

Engineers require high-quality data for the design and implementation of today’s software, especially in the context of machine learning (ML). This puts an emphasis on the need for the publication and sharing of data from and between organizations, public as well as private. Following the paradigm of open innovation, open data provide a mechanism to increase the availability of information, offeri
