Complex dynamics of water quality mixing in a warm mono-mictic reservoir

Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions and other factors such as oligotrophication, eutrophication, and microbial activities. In addition, hydrological variability can cause greater differences in water residence time and cycling of constituents in man-made lakes (reservoirs) than in natural lakes. Thus, investigations are n

Preparation and thermophysical property analysis of nanocomposite phase change materials for energy storage

Paraffin wax and various nanoparticles (CuO, Al2O3 and Fe3O4) were used as matrix and heat conduction enhancer of phase change materials (PCMs), respectively. The dispersant Span 80 was added into the nanocomposite to provide stable PCMs. Based on analyses of melting and freezing curves and infrared thermal imaging tests, the phase change latent heat, viscosity, and thermal conductivity of the nan

Occupation, socioeconomic status and chronic obstructive respiratory diseases – The EpiLung study in Finland, Estonia and Sweden

Objective: To study occupational groups and occupational exposure in association with chronic obstructive respiratory diseases. Methods: In early 2000s, structured interviews on chronic respiratory diseases and measurements of lung function as well as fractional expiratory nitric oxide (FENO) were performed in adult random population samples of Finland, Sweden and Estonia. Occupations were categor

Assembly of Multicompartment Glycopolymer Worms in Aqueous Solution

Hierarchical self-assembly is a versatile technique that allows the formation of many complex architectures on the nano- and microscale. However, many of these structures are formed in harsh organic solvents with nonbiocompatible polymers. Here, we investigate in more detail a synthetic path to produce biologically compatible, crosslinked, multicompartment worms (MCWs) in aqueous solution by incor

Deep learning-based classification of organs at risk and delineation guideline in pelvic cancer radiation therapy

Deep learning (DL) models for radiation therapy (RT) image segmentation require accurately annotated training data. Multiple organ delineation guidelines exist; however, information on the used guideline is not provided with the delineation. Extraction of training data with coherent guidelines can therefore be challenging. We present a supervised classification method for pelvis structure delineat

Critical perspectives on Arts on Prescription

The positive outcomes of engaging in the arts are increasingly reported in the research literature, supporting the use of the arts to enhance individual and community health and wellbeing. However, little attention is given to the less positive aspects of arts engagement. In some countries, healthcare practitioners and link workers can refer service-users experiencing mental health issues to socia

Association between flexibility activity and blood-pressure change among older adults in Japan : A 5-year longitudinal study

This longitudinal study examined the relationship between flexibility-activity and blood-pressure (BP) change among older adults in Japan. Our study included 452 older adults who took part in our survey in both 2012/2013 and 2017/2018. The seated systolic blood pressure (SBP) and diastolic BP (DBP) were measured both at baseline and at the 5 years follow-up. The frequencies of the different physic

Kan træer have en form for bevidsthed? Kan de handle på eget initiativ?Thomas Arentzen er ekspert indenfor tidlig kristen poesi og litteratur og har forsket i de tidlige kristnes opfattelse af træer. Sidste efterår var Arentzen i Istanbul. Her mødte han træer, som har stået på hellige steder i hundredvis af år.

Detection of Short Supraventricular Tachycardias in Single-lead ECGs Recorded Using a Handheld Device

Short supraventricular tachycardias (S-SVTs) have been associated with a higher risk of developing atrial fibrillation (AF). Hence, identification of participants with such arrhythmias may increase the yield of AF screening. However, the lower signal quality of ECGs recorded using handheld screening devices challenges the detection of S-SVT. In the present work, a new method for detection of S-SVT

Estimation of f-wave Dominant Frequency Using a Voting Scheme

Atrial fibrillation (AF) is the most common heart arrhythmia, characterized by the presence of fibrillatory waves (f-waves) in the ECG. We introduce a voting scheme to estimate the dominant atrial frequency (DAF) of f-waves. Methods: We analysed a subset of Holter recordings obtained from the University of Virginia AF Database. 100 Holter recordings with manually annotated AF events, resulting in

Standardization of serum creatinine is essential for accurate use of unbiased estimated GFR equations : Evidence from three cohorts matched on renal function

Background: Differences in the performance of estimated glomerular filtration rate (eGFR) equations have been attributed to the mathematical form of the equations and to differences between patient demographics and measurement methods. We evaluated differences in serum creatinine (SCr) and eGFR in cohorts matched for age, sex, body mass index (BMI) and measured GFR (mGFR). Methods: White North Ame

The COVID-19 pandemic and the timing of government response : A comparison of four Nordic countries March–June 2020

Objectives: The aim is to compare Sweden, Denmark, Finland and Norway regarding government response to the COVID-19 pandemic in mid-March–June 2020 using the Oxford Government Response Tracker. Study design: Descriptive longitudinal ecological study. Methods: Descriptive analysis of time series data. Results: Sweden displayed a far lower response index in March. By late April indexes were similar.

Trade and the transnational cleavage in European party politics

Theorists of the transnational cleavage, defined as a political reaction against European integration and immigration, also regularly conceptualise international trade preferences as a component of this contemporary societal divide. Yet empirical analyses of this cleavage focus on the former two topics, while trade and the transnational cleavage has not been systematically investigated. Making use

A phylogenomic perspective on the relationships of subfamilies in the family Geometridae (Lepidoptera)

Geometrid moths, the second largest radiation of Lepidoptera, have been the target of extensive phylogenetic studies. Those studies have flagged several problems in tree topology that have remained unanswered. We address three of those: (i) deep nodes of Geometridae (subfamilies Sterrhinae + Larentiinae, or Sterrhinae alone as sister to all other subfamilies), (ii) the taxonomic status of subfamil

An Overview of Plant-Based Protein Rich Products

Deleterious impact of animal meat production and consumption on environment and consumers health has developed interests for exploring relatively safer, healthier, and sustainable food sources. Promoting the production and consumption of plants as alternative to meat proteins do not merely conserve the ecosystem but also promote consumers health and well-being by consistent modification of their f
