An innovative coaxial dual-swirl combustor was developed to address the challenges of combustion instability and NOx emissions inherent to ammonia combustion. The combustor employs an inner swirler supplying a premixed ammonia/air stream and an outer swirler generating a premixed methane/air flame that stabilizes the inner ammonia flame. Combined large-eddy simulations (LES) and planar laser-induc

Svart kol (black carbon, BC) är partiklar som bildas vid ofullständig förbränning av biomassa och fossila bränslen, och sprids framför allt genom direkta utsläpp till luft. I naturen stannar BC kvar i århundraden till årtusenden, och har en negativ påverkan på både klimat och hälsa. I följande litteraturstudie har koncentrationer från sjösediment som sträcker sig ungefär 150 år tillbaka i tiden iBlack carbon (BC) are particles that are formed during incomplete combustion of biomass and fossil fuels. BC remains in nature for centuries to millennia, has an extensive spread and a negative impact on both climate and health. In the following literature study, concentrations from lake sediments stretching back approximately 150 years in Finland, Switzerland and China have been compiled. The co

Märta Måås-Fjetterström’s textile career was largely based on a collective effort. As a textile artist in her own workshop, she drew patterns that she let employed weavers weave. Together with a few other artists, she helped elevate the craft – the carpet – to the realm of art, by signing her works early on. After Märta Måås-Fjetterström’s death, Barbro Nilsson took over the role as artistic direc

This study investigated the effects of using multiple different acoustic and linguistic features for objective Speech Reception Threshold (SRT) estimation from Electroencephalography (EEG) data, using models that estimates the neural response (EEG data) from the corresponding feature stimulus, or vice versa. The SRT is a measurement of the speech volume Signal-to-Noise Ratio where the subject unde

Transient concurrent flame spread over solid surfaces involves multiple interacting physical processes, where simplified modelling with effective parameter identification is still challenging. This study presents a modelling framework that combines scaling-based formulation with Bayesian parameter inference to quantitatively capture the transient behaviors of concurrent flame spread. Experimental

Abstract in Polish:Artykuł omawia trzy skandynawskie filmy dokumentalne: Zaćmienie duszy (2000) fińskiej reżyserki Marji Pensali, Tankograd (2010) autorstwa Duńczyka Borisa Bertrama oraz Nadzy z Petersburga (2010) w reżyserii duńskiej twórczyni Ady Bligaard Søby. Każdy z dokumentów to portret wybranego miasta w Rosji i jego mieszkańców. Odwołując się do koncepcji takich jak „rosyjska dusza”, bytieThe article discusses three documentaries made since 2000 by Scandinavian filmmakers: the Finnish director Marja Pensala’s The Eclipse of the Soul (2000) and two films by Danish authors: Boris Bertram’s Tankograd (2010) and Ada Bligaard Søby’s The Naked of Saint Petersburg (2010). All the films are portraits of Russian cities and their residents. In my study, I draw on concepts such as the “Russia

Long-distance migrants face numerous challenges during their migration, with the spring migration timing being particularly important, as early arrival at the breeding grounds often enhances breeding success. Both innate and environmental factors influence migration timing in birds, and the earlier arrival of males than females is common among songbirds breeding in temperate zones. The great reed

In the future, buildings need to be energy resilient to tackle the energy crisis. This article introduces a concept for classifying the energy resilience of buildings in extreme cold and warm weather in Finland during blackouts. It presents a techno-economic comparison between an old and a new single-family building integrated with photovoltaic (PV) systems and batteries, analyzing their resilienc

Background: Motion sickness (MS) is a common complaint during most modes of travel. Several medications can be used to treat MS but are often accompanied by side-effects. Objective: To assess whether performing the Valsalva manoeuvre can influence the subjective feeling of MS in healthy individuals. Methods: We included 16 healthy participants (4 female) that underwent two sessions of MS induction

De 6-åriga läkarprogrammen ger legitimation och förskrivningsrätt direkt efter examen.En nationell arbetsgrupp har tagit fram förslag till hur läkarstudenter under grundutbildningen ska ges möjligheter att träna på läkemedelsbehandling samt hur lärosätena ska kunna examinera kunskaper och färdigheter.Gruppen föreslår ökad tydlighet i kedjan lärandemål–aktiviteter–examination, färdighetsträning i d

INTRODUCTION: Sex differences in symptomatic carotid artery stenosis have been reported with conflicting results, with knowledge gaps regarding the degree of carotid stenosis, management and preoperative ischaemic events. This study aimed to determine sex differences in symptomatic carotid artery stenosis prior to undergoing carotid endarterectomy (CEA) or carotid artery stenting (CAS).PATIENTS AN

The paper is a commentary on the tables in George Peurbach՚s Tabulae Eclypsium and presents their mathematical background with many of the tables analyzed and recalculated. These tables, based on the Alfonsine tradition, made possible more accurate and less tedious calculations of the circumstances of solar and lunar eclipses and were in many respects an improvement over previous similar tables. T

Over one third of the population develops cancer during their life-time and stroke associated with malignancy accounts for 10% of all hospitalized patients. With and improved survival and better life quality of patients with cancer, cancer related stroke is likely to increase. It is crucial to early diagnose an underlying malignancy to optimize treatment. It is known that a major mechanism is canc
