Smoke from western North American wildfires reached the stratosphere in large amounts in August 2017. Limb-oriented satellite-based sensors are commonly used for studies of wildfire aerosol injected into the stratosphere (OMPS-LP (Ozone Mapping and Profiler Suite Limb Profiler) and SAGE III/ISS (Stratospheric Aerosol and Gas Experiment III on the International Space Station)). We find that these m
OBJECTIVES: To evaluate the intra- and inter-rater agreement for myometrial lesions using Morphologic Uterus Sonographic Assessment terminology. METHODS: Thirteen raters with high (n = 6) or medium experience (n = 7) assessed 30 3-dimensional ultrasound clips with (n = 20) and without (n = 10) benign myometrial lesions. Myometrial lesions were reported as poorly or well defined and then systematic
Artificial groundwater recharge is commonly used for drinking water supply. The resulting water quality is highly dependent on the raw water quality. In many cases, pre-treatment is required. Pre-treatment improves the drinking water quality, although how and to what extent it affects the subsequent pond water quality and infiltration process, is still unknown. We evaluated two treatment systems b
Microcontrollers have become an integral part of modern everyday embedded systems, such as smart bikes, cars, and drones. Typically, microcontrollers operate under real-time constraints, which require the timely execution of programs on the resource-constrained hardware. As embedded systems are becoming increasingly more complex, microcontrollers run the risk of violating their timing constraints,
Perovskite solar cells have rapidly been developed over the past several years. Choice of the most suitable solar cell structure is crucial to improve the performance further. Here, we attempt to determine an optimum cell structure for methylammonium lead iodide (MAPbI3) perovskite sandwiched by "2 and spiro-OMeTAD layers, among planar heterojunction, mesoporous structure, and extremely thin absor
Terrestrial ecosystems are the largest sink for carbon, and their ecosystem gross primary productivity (GPP) regulates variations in atmospheric carbon dioxide (CO2) concentrations. Current process-based ecosystem models used for estimating GPP are subject to large uncertainties due to poorly constrained parameter values. In this study, we implemented a global sensitivity analysis (GSA) on paramet
Water flows through time are connected to specific instances of socionatural and sociotechnical assemblages of human and non-human components. We propose the concept of “water palimpsest” in order to characterize the complex histories of chemical and metabolic alterations embodied in water flows, potentially disruptive for humans and other living beings. Through the concept of palimpsest we interp
Abstract in French:Cette recherche s'intéresse à la mobilisation transnationale de la diaspora autour du vote externe et à l'implication des organisations diasporiques dans le processus électoral du pays d'origine. Plusieurs approches expliquent la transnationalisation politique des groupes diasporiques ; cependant, elles ne parviennent pas à clarifier (1) comment certains moments historiques (parThis research is concerned with transnational diaspora mobilisation around external voting and diaspora organisations’ involvement in the homeland electoral process. There are several approaches that explain the political transnationalisation of the diasporic groups; yet, they fail to clarify (1) how some historical moments (e.g., extending the voting right to non-resident nationals) can generate
OBJECTIVE: This systematic review aimed to assess the clinical outcomes of branched endovascular aneurysm repair (BEVAR) with inner branches (iBEVAR) and inner/outer branches (oBEVAR).DATA SOURCES: A systematic literature review was performed using the electronic bibliographic databases MEDLINE, Embase, Scopus, Web of Science, and the Cochrane Library up to May 2024.REVIEW METHODS: The review was
Context. TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups using nearly the same set of HARPS spectra have provided measurements of planetary masses that differ by ∼2σ. Aims. Our aim in this work is to solve the inconsistency in the published planetary masses by significa
Background: Access to improved water and sanitation infrastructures are key determinants of health. The sub-Saharan African region in particular is lagging behind the ambitious goal of the 2030 Agenda for Sustainable Development to ensure universal access to improved and reliable water and sanitation for all (Sustainable Development Goal (SDG) 6). Large mining projects can promote economic growth
IntroductionThe start of the 21st century is combined with the continuous replacement of classic C2/C3 chemistry with biological processes. This conversion process started at the end the 20th century and is combined with the integration of membrane processes as high selective and low energy consuming separation technologies in the production of fermentation based products. In fermentation based pr
Starting from the human and societal need to safeguard cultural heritage (CH) in order to connect to past generations’ knowledge and human experience, digital preservation (DP) is a common practice undertaken by cultural heritage organisations (CHOs). DP is heavily relying on the use of information and communication technology (ICT) as the fundamental enabling equipment. However, ICT is coming wit
Mobila exergames, det vill säga mobilspel som uppmuntrar användaren till fysisk aktivitet, har ökat i popularitet de senaste åren i samband med spel som Pokémon GO och Harry Potter: Wizards Unite, men stora brister råder fortfarande när det gäller tillgänglighet för personer med funktionsnedsättning. I denna uppsats undersöks tillgängligheten i ett antal mobila exergames på marknaden för att utredMobile exergames, that is mobile games that encourage the user to engage in physical activities, have increased in popularity during the last years due to the success of games such as Pokémon GO and Harry Potter: Wizards Unite, but there is a substantial lack when it comes to accessibility for people with disabilities. In this thesis the aim is twofold, first the accessibility of mobile exergames
Talade utrymningslarm installeras som en riskreducerande åtgärd i byggnader där det vistas personer som inte kan väntas ha god lokalkännedom. En grundförutsättning för att utrymningslarmet ska uppfylla sin riskreducerande effekt är att det är hörbart, därav är ett talöverföringsindex, STI, på 0,55 rekommenderat. STI är ett mått på taluppfattbarhet som inte tar hänsyn till den subjektiva upplevelseVoice evacuation alarms are installed as a risk mitigation measure in buildings where people reside who cannot be expected to have good local knowledge. Voice evacuation alarms have basic requirements that need to be meet such as auditability, where a speech transmission index, STI, of 0,55 is recommended. STI is a measure of speech intelligibility that does not include the subjective experience o
Vräkning är en av de mest ingripande åtgärder och traumatiserande upplevelser som någon, särskilt ett barn, kan vara med om. Under 2017 vräktes enligt Kronofogdemyndighetens statistik 392 barn och hyresskulder utgör den vanligaste orsaken till att en barnfamilj avhyses. I nästan hälften av fallen sker avhysningen för hyresskulder för belopp under 10 000 kronor. Detta trots att det är mer fördelaktEviction is one of the most traumatic experiences anybody experience – a fact which holds especially true for children. According to the statistics of the Swedish Enforcement Authority 392 children were evicted in Sweden during the year of 2017. Rental debt is the most common cause of the eviction of families, and in almost half of all cases the debt amounts to less than 10 000 SEK. That said, it
When evaluating future technologies for smart metering and automatic meter reading (AMR) E.ON Elnät Sverige AB has set up a pilot to test a communication technology supplied by Connode AB. Connode have developed a mesh radio solution based on 6LoWPAN, IPv6 over Low Powered Wireless Personal Area Network. By using this technology the communication unit on every meter is acting as both receiver and
