Ex-situ manometric activity test for evaluation of mainstream anammox in Moving Bed Biofilm Reactors

Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. The method was found to be reliable and re

Building Gender-Just Citizenship in Northern Ireland : Women’s Political Participation and Transversal Politics in a Deeply Divided Society

This thesis analyses women’s public, political participation, cross-community activities, and the potential for transversal citizenship in post-Agreement Northern Ireland through data collected in semi-structured interviews, participant observation and document analysis. The theoretical framework explores how gender, citizenship and ethno-nationalism intersect in deeply divided transitional societ

Derangement of the senses or alternate epistemological pathways? Altered consciousness and enhanced functioning

This article summarizes and integrates research on the relation between altered consciousness (including states and traits, as well as procedures and practices to induce them) and enhanced functioning. The latter include improved psychophysiological control as well as enhanced performance in controlled parapsychological experiments. Multiple studies on meditation, hypnosis, sensory homogenization,

Deconvoluting Energy Transport Mechanisms in Metal Halide Perovskites Using CsPbBr3 Nanowires as a Model System

Understanding energy transport in metal halide perovskites is essential to effectively guide further optimization of materials and device designs. However, difficulties to disentangle charge carrier diffusion, photon recycling, and photon transport have led to contradicting reports and uncertainty regarding which mechanism dominates. In this study, monocrystalline CsPbBr3 nanowires serve as 1D mod

Heterotrophic Foraminifera Capable of Inorganic Nitrogen Assimilation

Nitrogen availability often limits biological productivity in marine systems, where inorganic nitrogen, such as ammonium is assimilated into the food web by bacteria and photoautotrophic eukaryotes. Recently, ammonium assimilation was observed in kleptoplast-containing protists of the phylum foraminifera, possibly via the glutamine synthetase/glutamate synthase (GS/GOGAT) assimilation pathway impo

Antibiotic Prescription Rates After eVisits Versus Office Visits in Primary Care : Observational Study

BACKGROUND: Direct-to-consumer telemedicine is an increasingly used modality to access primary care. Previous research on assessment using synchronous virtual visits showed mixed results regarding antibiotic prescription rates, and research on assessment using asynchronous chat-based eVisits is lacking.OBJECTIVE: The goal of the research was to investigate if eVisit management of sore throat, othe

Exploring Emotional Distress, Psychological Traits and Attitudes in Patients with Chronic Migraine Undergoing OnabotulinumtoxinA Prophylaxis versus Withdrawal Treatment

This explorative cross-sectional study aims at exploring emotional distress, psychological profiles, and the attitude towards receiving psychological support in eighty-seven patients with chronic migraine (CM) undergoing OnabotulinumtoxinA prophylactic treatment (OBT-A, n = 40) or withdrawal treatment (WT, n = 47). The outcomes were explored through a specific battery of questionnaires. 25% of pat

First-order synchronization transition in a large population of strongly coupled relaxation oscillators

Onset and loss of synchronization in coupled oscillators are of fundamental importance in understanding emergent behavior in natural and man-made systems, which range from neural networks to power grids. We report on experiments with hundreds of strongly coupled photochemical relaxation oscillators that exhibit a discontinuous synchronization transition with hysteresis, as opposed to the paradigma

Cerebrospinal fluid influx drives acute ischemic tissue swelling

Stroke affects millions each year. Poststroke brain edema predicts the severity of eventual stroke damage, yet our concept of how edema develops is incomplete and treatment options remain limited. In early stages, fluid accumulation occurs owing to a net gain of ions, widely thought to enter from the vascular compartment. Here, we used magnetic resonance imaging, radiolabeled tracers, and multipho

Basins of attraction for chimera states

Chimera states - curious symmetry-broken states in systems of identical coupled oscillators - typically occur only for certain initial conditions. Here we analyze their basins of attraction in a simple system comprised of two populations. Using perturbative analysis and numerical simulation we evaluate asymptotic states and associated destination maps, and demonstrate that basins form a complex tw

A Prospective Observational Cohort Study on Pharmacological Habitus, Headache-Related Disability and Psychological Profile in Patients with Chronic Migraine Undergoing OnabotulinumtoxinA Prophylactic Treatment

Chronic Migraine (CM) is a disabling neurologic condition with a severe impact on functioning and quality of life. Successful therapeutic management of patients with CM is complex, and differences in therapeutic response could be attributable to genetically determined factors, sensitivity to pharmacological treatment, psychosocial and relational factors affecting the patient's compliance and appro

Numerical simulation of solid oxide fuel cells comparing different electrochemical kinetics

Solid oxide fuel cells (SOFCs) produce electricity with high electrical efficiency and fuel flexibility without pollution, for example, CO2, NOx, SOx, and particles. Still, numerous issues hindered the large-scale commercialization of fuel cell at a large scale, such as fuel storage, mechanical failure, catalytic degradation, electrode poisoning from fuel and air, for example, lifetime in relation

A multi-input and single-output voltage control for a polymer electrolyte fuel cell system using model predictive control method

Efficient and robust control strategies can greatly contribute to the reliability of fuel cell systems, and a stable output voltage is a key criterion for evaluating a fuel cell system's reliability as a power source. In this study, a polymer electrolyte fuel cell (PEFC) system model is developed, and its performances under different operating conditions are studied. Then two different novel contr

Survival of infants born with esophageal atresia among 24 international birth defects surveillance programs

Background: Esophageal atresia (EA) affects around 2.3–2.6 per 10,000 births world-wide. Infants born with this condition require surgical correction soon after birth. Most survival studies of infants with EA are locally or regionally based. We aimed to describe survival across multiple world regions. Methods: We included infants diagnosed with EA between 1980 and 2015 from 24 birth defects survei

Routine blood tests are associated with short term mortality and can improve emergency department triage : A cohort study of >12,000 patients

Background: Prioritization of acutely ill patients in the Emergency Department remains a challenge. We aimed to evaluate whether routine blood tests can predict mortality in unselected patients in an emergency department and to compare risk prediction with a formalized triage algorithm. Methods: A prospective observational cohort study of 12,661 consecutive admissions to the Emergency Department o

18th congress of european mycologists bioblitz 2019 – naturalists contribute to the knowledge of mycobiota and lichenobiota of białowieża primeval forest

A total of 561 records of 233 species of fungi are reported from the Polish part of Białowieża Forest as a result of a short-term inventory that was conducted during the 18th Congress of European Mycologists (September 18–29, 2019). Four species new to Poland (Bryocentria brongniartii, Tremella coppinsii, T. hypocenomycis, and Zevadia peroccidentalis), and eight species new to Białowieża Primeval
