This paper presents experimental and numerical investigations of liquid droplet/air two-phase flow through face masks. The study aims to provide a deeper understanding of the droplet filtration process, generate experimental data for modeling droplet/air two-phase flow across face masks, and develop and validate numerical models to simulate droplet motion through the mask and downstream. Droplet i
Introduction: Intact cord resuscitation promotes zero separation and facilitates skin-to-skin contact, regardless of delivery mode. Therefore, this study aims to illuminate parents' experiences of intact cord resuscitation in the mother's bed. Method: Interviews with seven mothers, one father and seven couples were analysed using Lindseth and Norberg's phenomenological hermeneutics. Results: The a
Att läsa Mario Vargas Llosas Staden och hundarna är en utmaning för svenska universitetsstudenter som läser spanska som främmande språk, men trots detta visar kursutvärderingar att de tenderar att uppskatta upplevelsen. Denna studie fokuserar på att utforska studenternas läsprocess och deras reaktioner på texten genom ett läsloggprojekt. Felskis (2008) kategorier igenkänning, kunskap, förtrollning
Low-temperature combustion (LTC) concepts, such as homogeneous charge compression ignition (HCCI) and partially premixed combustion (PPC), aim to reduce in-cylinder temperatures in internal combustion engines, thereby lowering emissions of nitrogen oxides (NOx) and soot. These LTC concepts are particularly attractive for decarbonizing conventional diesel engines using renewable fuels such as metha
Objectives: Experimental and small human studies have indicated that high total adiponectin levels have beneficial cardiometabolic effects. In contrast, however, high total adiponectin levels are also associated with higher all-cause and cardiovascular mortality in thoroughly adjusted epidemiological studies. To gain further insight into these seemingly contradictory results, we report results on
Ecological modernisation has together with sustainable development reached a hegemonic status in the current environmental discourse. In the 1970's, the environmental crisis was blamed on modernity and technology and environmental protection was a prioritised area within the environmental movement. Today, it is believed that the crisis is to be solved with technical innovations and keywords ar
Studiens syfte var att ta reda på hur mötet med patienterna påverkas när terapeuterna är trötta på sina arbeten. Det är en kvalitativ studie med sex öppet riktade intervjuer som underlag. Informanterna var anställda på den allmänpsykiatriska mottagning där även författarna arbetar. Materialet transkriberades ordagrant och texterna granskades och analyserades. I studiens huvudsakliga slutsats framk
Sedan de tidiga mänskliga civilisationerna har människan använt djur till diverse ändamål, såsom föda, kläder och arbetsredskap. I takt med människans tekniska framsteg har djur börjat användas som testsubjekt, så kallade försöksdjur, för att säkerställa att olika ämnen och behandlingar är säkra. Avseende transplantationskirurgi har djur spelat en avgörande roll i utvecklingen, och det är en reellSince early human civilizations, humans have used animals for a variety of purposes, such as food, clothing, and tools. As human technology has advanced, animals have been used as test subjects, known as laboratory animals, to ensure that various substances and treatments are safe. In transplant surgery, animals have played a crucial role in its development and there is the potential for further s
Small cell lung cancer (SCLC) is a highly aggressive form of cancer, characterized by a particularly poor prognosis. Subsequently, it has a very low five-year survival rate of only 6%. At the clinic, patients are either diagnosed at advanced stages where care is more palliative and with few therapeutic options or, when diagnosed at earlier stages, respond very positively to first-line treatments b
A significant proportion of the diversity of species seen today are insects and their host plants, and the evolutionary mechanisms behind their radiation have long captured the interest of biologists. The peacock flies of the large genus Tephritis (Tephritidae) use different host plants in the family Asteraceae for their reproduction. There is variation both in use of host plant species and in the

Reliable prediction tools are yet to be developed for estimating the accurate acoustic performance of lightweight structures, which are vital especially in the design process. This paper presents a sound insulation prediction model based on artificial Neural Networks (NN) to estimate acoustic performance for airborne and impact sound insulation of floor structures. At an initial stage, the predict
Let NDTIME(f(n),g(n)) denote the class of problems solvable in O(g(n)) time by a multi-tape Turing machine using an f(n)-bit non-deterministic oracle, and let DTIME(g(n)) = NDTIME(0, g(n)). We show that if the all-pairs shortest paths problem (APSP) for directed graphs with N vertices and integer edge weights within a super-exponential range { -2Nk+o(1),.,2Nk+o(1)}, k≥1 does not admit a truly subc
Occupational balance (OB) may be a major determinant of health outcomes due to its role in bringing a sense of purpose in the occupations that are personally experienced as a process of getting health and wellness. The Occupational Balance Questionnaire (OBQ) is a reliable instrument for measuring OB, although it has not been adapted and validated in Spain so far; therefore, this study had a doubl
The use of learning-based methods for vehicle behavior prediction is a promising research topic. However, many publicly available data sets suffer from class distribution skews which limits learning performance if not addressed. This paper proposes an interaction-aware prediction model consisting of an LSTM autoencoder and SVM classifier. Additionally, an imbalanced learning technique, the multicl
Indoor combustion processes associated with cooking, heating, and smoking are a major source of aerosols in Jordanian dwellings. To evaluate human exposure to combustion-generated aerosols in Jordanian indoor environments, regional inhaled deposited dose rates of indoor aerosols (10 nm to 25 µm) were determined for different scenarios for adult occupants. The inhaled deposited dose rate provides a
In this audio paper I will focus on two ideas. The first is the ephemeral city. The conscious re-imagining of the cityscape, from elements ranging from the historic to the fantastical, can effect an individual’s sense of place as much as the physical structures that comprise it. These imagined – or ephemeral – cities can be a way of coming to grips with an urban environment changing in rapid and dis
Tropical forests contribute a major sink for anthropogenic carbon emissions essential to slowing down the buildup of atmospheric CO2 and buffering climate change impacts. However, the response of tropical forests to more frequent weather extremes and long-recovery disturbances like fires remains uncertain. Analyses of field data and ecological theory raise concerns about the possibility of the Ama
OBJECTIVES: To describe clinical characteristics and prognosis related to heart failure (HF) phenotypes in a community-based population by applying a novel algorithm to obtain ejection fractions (EF) from electronic medical records. DESIGN: Retrospective population-based cohort study. SETTING: Data were collected for all patients with HF in Southwest Sweden. The region consists of three acute care
We examine whether exposure to gender inequality at export destinations affects the gender wage gap in exporting firms. We motivate the analysis through a stylized model where wages depend on worker productivity, and men have a comparative advantage when trading with gender-unequal countries due to customer discrimination. Empirically, we use high-quality matched employer-employee data from Sweden
