Synthesis and experimental study of novel double perovskite Ba2NixCo2−xO6 as promising oxygen carrier materials for CO2 capture application

Novel oxygen-deficient double-perovskite type oxide Ba2NixCo2−xO6 was applied to produce O2/CO2 mixed stream gas for oxyfuel combustion application. A series of different Co concentration substituted Ba2NixCo2−xO6 was synthesized by an EDTA-citrate sol-gel combustion method. The oxygen carriers, Ba2Ni0.25Co1.75O6, Ba2Ni0.45Co1.55O6, Ba2Ni0.65Co1.35O6 and Ba2Ni0.85Co1.15O6 were c\characterized by s

Diagnosis of Gestational Diabetes Mellitus with Point-of-Care Methods for Glucose versus Hospital Laboratory Method Using Isotope Dilution Gas Chromatography-Mass Spectrometry as Reference

Background. In Sweden, both glucose analyzers in accredited laboratories and point-of-care glucose devices are used for gestational diabetes mellitus (GDM) diagnosis. The aim of this study was to compare the diagnostic performance of the HemoCue Glucose 201+ (HC201+) and RT (HC201RT) systems with that of the hospital central laboratory hexokinase method (CL) based on lyophilized citrate tubes, usi

Diagnostic Stability of Mild Cognitive Impairment, and Predictors of Reversion to Normal Cognitive Functioning

Objective: Studies that investigate predictive factors for spontaneous recovery (reversion) from mild cognitive impairment (MCI) are only beginning to emerge, and the long-term course of MCI is not properly understood. We aimed to investigate stability of the MCI diagnosis, predictors for reversion, as well as the trajectory of MCI over the course of 12 years. Materials and Methods: Data were draw

A Quantitative Analysis of the Role of Oxygen Tension in FLASH Radiation Therapy

Purpose: Recent demonstrations of normal tissue sparing by high-dose, high-dose-rate FLASH radiation therapy have driven considerable interest in its application to improve clinical outcomes. However, significant uncertainty remains about the underlying mechanisms of FLASH sparing and how deliveries can be optimized to maximize benefit from this effect. Rapid oxygen depletion has been suggested as

Oral provocation of patients allergic to sesquiterpene lactones with German chamomile tea to demonstrate possible systemic allergic dermatitis

Background: Most patients with contact allergy to Asteraceae plants are patch test positive to sesquiterpene lactone mix (SLM). There are several reports among these patients of a flare-up of hand eczema after ingestion of food and beverages originating from Asteraceae plants. Aim: To investigate whether German chamomile tea can elicit systemic allergic dermatitis. Patients and Methods: Individual

Being Different but Striving to Seem Normal : The Lived Experiences of People Aged 50+ with ADHD

This qualitative study explored the day-to-day life of people aged 50+ diagnosed with ADHD. A phenomenological-hermeneutical method was chosen for the analysis. Two themes including sub-themes were revealed. The first theme, Being different and trying to handle my inner self, concerned emotional self-regulation, emotional resilience, social skills, and personal resource management. The second them

Hypoxia-induced release, nuclear translocation, and signaling activity of a DLK1 intracellular fragment in glioma

Glioblastoma multiforme is characterized in part by severe hypoxia associated with tumor necrosis. The cellular response to hypoxia can influence several properties of tumor cells associated with aggressive tumor growth, including metabolic adaptations and tumor cell migration and invasion. Here, we found that Delta Like Non-Canonical Notch Ligand 1 (DLK1) expression was elevated as compared with

Investigating information seeking in ravens (Corvus corax)

Measuring the responses of non-human animals to situations of uncertainty is thought to shed light on an animal’s metacognitive processes; namely, whether they monitor their own knowledge states. For example, when presented with a foraging task, great apes and macaques selectively seek information about the location of a food item when they have not seen where it was hidden, compared to when they

Differential gene expression of Plasmodium homocircumflexum (lineage pCOLL4) across two experimentally infected passerine bird species

Plasmodium parasites are present in a wide range of host species, some of which tend to be more susceptible than others, potentially as an outcome of evolved tolerance or resistance. Common starlings seem to cope with malaria infection while common crossbills are more susceptible to the same infections. That raises the question if the parasites rely on the same molecular mechanisms regardless of h

Comparison of the duration of hospital stay after laparoscopic or open distal pancreatectomy : randomized controlled trial

Background: Studies have suggested that laparoscopic distal pancreatectomy (LDP) is advantageous compared with open distal pancreatectomy (ODP) regarding hospital stay, blood loss and recovery. Only one randomized study is available, which showed enhanced functional recovery after LDP compared with ODP. Methods: Consecutive patients evaluated at a multidisciplinary tumour board and planned for sta

On the Stability of Solitary Water Waves with a Point Vortex

This paper investigates the stability of traveling wave solutions to the free boundary Euler equations with a submerged point vortex. We prove that sufficiently small-amplitude waves with small enough vortex strength are conditionally orbitally stable. In the process of obtaining this result, we develop a quite general stability/instability theory for bound state solutions of a large class of infi

The microevolutionary response to male-limited X-chromosome evolution in Drosophila melanogaster reflects macroevolutionary patterns

Due to its hemizygous inheritance and role in sex determination, the X-chromosome is expected to play an important role in the evolution of sexual dimorphism and to be enriched for sexually antagonistic genetic variation. By forcing the X-chromosome to only be expressed in males over >40 generations, we changed the selection pressures on the X to become similar to those experienced by the Y. This

Mild to Moderate Cognitive Impairment Does Not Affect the Ability to Self-Report Important Symptoms in Patients With Cancer : A Prospective Longitudinal Multinational Study (EPCCS)

Context: Patients with advanced cancer commonly suffer from both distressing symptoms and cognitive impairment, but the effect of cognitive impairment on the reliability and validity of symptom self-report is unknown. Objectives: To evaluate the reliability and validity of symptom self-report in cancer outpatients with and without mild to moderate cognitive impairment. Methods: This was an analysi

Exploiting Flexible Memristors Based on Solution-Processed Colloidal CuInSe2 Nanocrystals

Compared to analogous bulk materials, colloidal nanocrystals have presented a powerful platform for building up electronic devices on the nano/micrometer scale and flexible portable electronic apparatus with the benefits of solution-based processing approach at room temperature. Herein, memristors based on CuInSe2 (CISe) colloidal nanocrystals prepared using a solution-based process at room temper

Managing an altered social context—Patients experiences of staying away from home while undergoing proton beam therapy

Aim: To illuminate the experience of an altered social context for patients with primary brain tumours living away from home while undergoing proton beam therapy. Design: A descriptive, qualitative cross-sectional interview study. Methods: Nineteen patients were interviewed between December 2015–August 2016, either during (N = 7) or before and after (N = 12) their proton beam therapy. A hermeneuti

The HepMC3 event record library for Monte Carlo event generators

In high-energy physics, Monte Carlo event generators (MCEGs) are used to simulate the interactions of high energy particles. MCEG event records store the information on the simulated particles and their relationships, and thus reflect the simulated evolution of physics phenomena in each collision event. We present the HepMC3 library, a next-generation framework for MCEG event record encoding and m

Bureaucracy and Growth

We revisit the hypothesis that a Weberian bureaucracy enhances economic growth. Theoretically, we develop arguments for why such a bureaucracy may enhance growth and discuss plausible counterarguments. Empirically, we use new measures capturing various Weberian features in countries across the world, with some time series extending back to 1789. The evidence base from previous large-N studies is s

Staying or leaving? The effects of university availability on educational choices and rural depopulation

Universities are often viewed as engines of local economic growth that could mitigate rural depopulation. However, university studies might make individuals more prone to move. We explore this issue in a quasi-experiment arising due to a sudden reduction in the number of student places at a regional university in northern Sweden in 1998. We find that the reduction in student places affected both e
