A circular economy maximizes the value of material resources and minimizes greenhouse gas emissions, resource use, waste and pollution. We will posit that circularity needs to be understood as a property of a system (e.g., the mobility system of a city), rather than a property of an individual product or service (e.g., a car or a car-sharing service). Hence, there is a need for more knowledge on h
BackgroundRight ventricular (RV) function is a major determinant of outcome in patients with pulmonary hypertension. Cardiac magnetic resonance (CMR) is gold standard to assess RV ejection fraction (RVEFCMR), however this is a crude measure. New CMR measures of RV function beyond RVEFCMR have emerged, such as RV lateral atrio-ventricular plane displacement (AVPDlat), maximum emptying velocity (S’C
Elevated blood pressure (BP) is a worldwide burden, leading to over 10 million deaths yearly. May Measurement Month (MMM) is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for BP screening. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of
Electrocardiographic (ECG) criteria for the diagnosis of inferior myocardial infarction (IMI) have high specificity but low sensitivity. Vectorcardiographic IMI criteria attain higher sensitivity without sacrificing specificity. One approach to improving ECG interpretation is to synthesize VCG loops from the 12-lead ECG. The performance of synthesized VCG (SVCG) was assessed, using the Frank VCG c
Ethics, Science and Society: Challenges for BioPolitics is an international project of academic research, scientific dissemination, and social and political responsibility, sponsored by the Luso-American Development Foundation. Its main objective is to stress the importance of this triptych-style approach – ethics, science, society – to address some of the current and major challenges facing huma
Purpose. This study aimed to investigate the effects of using hand grip or resisted wrist extension as the reference contraction, and two electrode positions, on field recordings of forearm extensor muscle activity. Materials and methods. Right forearm extensor muscle activity was recorded using two electrode pairs (over the most prominent part (position 2) and proximal to that (position 1)) durin
We ask what caused poverty to decline in Brazil during the first decade of the 21st century. Our contribution lies in the introduction of a structural change perspective to assess the evolution of poverty by considering the sectoral impact of growth and the social policies at the federal, state and municipal level. By structural change we mean the recomposition of output and employment over time.
Populärvetenskaplig sammanfattning Främsta källan till läkemedel i miljön är att vi människor inte bryter ner det vi stoppar i oss och att avloppsreningsverk inte heller helt eliminerar resterna i reningsprocessen. Koncentrationerna i naturen är dock ofta låga men vattenlevande organismer kan ackumulera vissa läkemedel så koncentrationen i deras kroppar blir högre än i omgivningen, så kallad bioacPharmaceuticals are found at low concentrations (ng/L) in aquatic environments but bioaccumulation may result in aquatic organisms reaching internal effect levels (µg/L). Environmental hazard assessments include standardized bioaccumulation tests but contrary to the model substances around which the frameworks are built most pharmaceuticals are designed to mimic endogenic chemicals, ionizable, and
Anthropogenic pressure in the high altitude lakes such as Titicaca and Uru (Bolivia) may favor the production of methylmercury (MeHg) known to accumulate in trophic chains. Periphyton associated with emerged aquatic plants (totoras) from the lake shores accumulates and demethylates MeHg providing a potential cost-effective water treatment technique. In this laboratory study, we measured the MeHg u
Efficient unit propagation for clausal constraints is a core building block of conflict-driven clause learning (CDCL) Boolean satisfiability (SAT) and lazy clause generation constraint programming (CP) solvers. Conflict-driven pseudo-Boolean (PB) solvers extend the CDCL paradigm from clausal constraints to integer linear constraints, also known as (linear) PB constraints. For PB solvers, many diff
BACKGROUND: In December 2013, it was discovered that drinking water supplied to one third of the households in Ronneby, southern Sweden, was highly contaminated by PFAS (sum level >10,000 ng/L) originated from firefighting foams used at a nearby military airport.OBJECTIVES: To report serum PFAS levels of Ronneby residents participating in a biomonitoring program, and to describe the variation by a
Camouflage may promote fitness of given phenotypes in different environments. The tawny owl (Strix aluco) is a color polymorphic species with a gray and brown morph resident in the Western Palearctic. A strong selection pressure against the brown morph during snowy and cold winters has been documented earlier, but the selection mechanisms remain unresolved. Here, we hypothesize that selection favo
One aim of the Bunkeflo project is to evaluate if daily school physical activity (PA) is associated with higher final school grades and improved eligibility for upper secondary school. One elementary school extended PA throughout elementary school to 200 minutes/week while control schools continued with in mean 60 minutes/week. We then registered final school grades and eligibility for upper secon
Flight activity recorders have recently confirmed that alpine and common swifts spend the majority of their non-breeding period on the wing, which may last 6–10 months. Here we test the hypothesis that the closely related pallid swift, a species with a breeding distribution around the Mediterranean, lead a similar aerial life-style during its migration and wintering periods. The pallid swift usual
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract their gaseous envelope. Previously, we have studied the growth and migration of an isolated planet in an evolving disc. Here, we generalise such models to include the mutual gravitational interaction between a high number of growing planetary bodi
Mozambique is one of the largest coal exporters in Africa. Usually miningactivities generate polluted water that is discharged into the Zambezi river basin in the Moatize area without treatment, increasing the risk both to the local environment and to public health because of this water containing significant amounts of metals and metalloids. At the same time, Mozambique is one of the largest prod
The evolution of assortative mating is a key part of the speciation process. Stronger assortment, or greater divergence in mating traits, between species pairs with overlapping ranges is commonly observed, but possible causes of this pattern of reproductive character displacement are difficult to distinguish. We use a multidisciplinary approach to provide a rare example where it is possible to dis
Animal reproductive proteins, especially those in the seminal fluid, have been shown to have higher levels of divergence than non-reproductive proteins and are often evolving adaptively. Seminal fluid proteins have been implicated in the formation of reproductive barriers between diverging lineages, and hence represent interesting candidates underlying speciation. RNA-seq was used to generate the
