Relative peripheral blood volume changes induced by premature ectopic beats and their role in hemodialysis

Hemodialysis patients often suffer from cardiovascular disorders and uremic neuropathy, increasing the propensity to homeostatic imbalance that, in turn, may result in intradialytic complications like cramp, nausea, and, worse, hypotension. Ectopic beats, being abundant in such patients, may lead to imbalance through repeated, sudden drops in blood pressure. By exploring the properties of postecto

Prediction of intradialytic hypotension using PPG and ECG

Intradialytic hypotension (IDH) is the most common complication during hemodialysis; early prediction and prevention of IDH would dramatically improve the living conditions for patients with end stage renal disease. A recently published study suggests that a decrease in the envelope of the photoplethysmograpy (PPG) signal can be used for predicting acute symptomatic IDH. In the present study, the

Detection of heart rate turbulence in photoplethysmographic signals

In this study, alterations in the cardiovascular system caused by ventricular premature beats (VPBs) are investigated by analyzing the photoplethysmographic (PPG) signal. A simple algorithm for PPG-based detection of VPBs is devised and evaluated, and then employed for the analysis of heart rate turbulence (HRT), here labelled "pulse rate turbulence" (PRT). The pulse transit time is also studied a

Welfare State Supporter and Civil Society Activist: Church of Sweden in the “Refugee Crisis” 2015

2015 was a year of an unprecedented migration from the Middle East to Europe. Sweden received almost 163,000 asylum applications. The civil society, including the former state church, took a notable responsibility. In a situation where the welfare systems are increasingly strained, and both the welfare state and the majority church are re-regulated, we ask: how does this play out in local contexts

Quasi-free-standing monolayer hexagonal boron nitride on Ni

The electronic structure of monolayer hexagonal boron nitride grown on Ni by the diffusion and precipitation method was studied by x-ray absorption spectroscopy, emission spectroscopy, x-ray photoelectron spectroscopy and micro-ultraviolet photoemission spectroscopy. No indication of hybridization between h-BN π and Ni 3d orbitals was observed. That is, the monolayer h-BN was found to be in the qu

This article explores the genesis of the diplomatic law of international organizations in science and the doctrine of international law of Uzbekistan. The theoretical principles and the legal content of the diplomatic law of international organizations are learned. The inter-branch nature of the diplomatic law of international organizations as the sub-branch of law is disclosed.

Applying the theory of planned behavior to explain geospatial data sharing for urban planning and management : Cases from urban centers in Tanzania

This paper illustrates the potential use of the theory of planned behavior as a guiding framework for understanding intentions and behavior in geospatial data sharing in Tanzania. A structured questionnaire survey, was constructed and sent to local governments as well as academic and private organizations that are major producers and/or users of geodata. The questionnaire covered issues of how col

Maintaining cognitive function with internet use : A two-country, six-year longitudinal study

Objectives: Maintaining good cognitive function with aging may be aided by technology such as computers, tablets, and their applications. Little research so far has investigated whether internet use helps to maintain cognitive function over time.Design: Two population-based studies with a longitudinal design from 2001/2003 (T1) to 2007/2010 (T2).Setting: Sweden and the Netherlands.Participants: Ol

Renal concentration capacity in adult patients with urinary tract infections

The maximal urine concentration capacity was studied in patients with acute pyelonephritis and in patients with clinically diagnosed acute cystitis. In the former group renal concentration ability was reduced in 16 of 22 patients and improved in all but two patients. Among patients with symptoms of acute cystitis 6 of 22 had a concentration capacity below 2 SD of normal values. Several of these pa

Massive MIMO with a Generalized Channel Model : Fundamental Aspects

Massive multiple-input multiple-output (MIMO) is becoming a mature technology, and has been approved for standardization in the 5G space. Although there are many papers on the theoretical analysis of massive MIMO, the majority of relevant work assumes the simplified, yet overly idealistic, Kronecker-type model for spatial correlation. Motivated by the deficiencies of the Kronecker model, we invoke

Phase Noise Compensation for OFDM Systems Exploiting Coherence Bandwidth

Millimeter-wave (mmWave) systems must overcome severe phase noise impairment to exploit its full advantage (e.g. high data rate). However, the estimation of phase noise combined with wireless channel requires not only high-computational complexity, but also does not guarantee a stable solution. In this paper, the fact that the coherence bandwidth of a mmWave system is much larger than those of con

High spin states of the normally deformed bands of y 83

Level lifetime and side-feeding time measurements were performed on the excited states of the normally deformed bands of Y83 using the Doppler-shift attenuation method (DSAM). The high spin states of Y83 were populated using the fusion-evaporation reaction Ni58(S32,α3p)Y83 at 135 MeV. Twenty-two level lifetime and side-feeding times were determined in most of the cases by comparing the line shapes

Non-invasive evaluation of the effect of metoprolol on the atrioventricular node during permanent atrial fibrillation

The aim of this study was to evaluate changes in AV nodal properties during administration of metoprolol, using a novel ECG-based method for parameter estimation. The AV nodal parameters account for the probability of an impulse not passing through the fast pathway, the absolute refractory periods of the slow and fast pathways (aRPs and aRPf), representing the functional refractory period, and rel

Prevalence of intimate partner violence against women in Sweden and Spain : A psychometric study of the 'Nordic paradox'

The high prevalence of intimate partner violence against women (IPVAW) in countries with high levels of gender equality has been defined as the "Nordic paradox". In this study we compared physical and sexual IPVAW prevalence data in two countries exemplifying the Nordic paradox: Sweden (N = 1483) and Spain (N = 1447). Data was drawn from the European Union Agency for Fundamental Rights Survey on v

Diffusion of sustainable HVAC innovations in BIM platforms

Sustainability attributes of building ventilation products have considerable impacts on building performance aspects such as energy efficiency and indoor environmental quality. Heating, Ventilation and Air Conditioning (HVAC) manufacturers allocate resources to develop innovating ideas for improving the sustainability attributes of their products. The diffusion of those sustainable innovations, ho

Positron emission tomography visualized stimulation of the vestibular organ is localized in Heschl's gyrus

The existence of a human primary vestibular cortex is still debated. Current knowledge mainly derives from functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) acquisitions during artificial vestibular stimulation. This may be problematic as artificial vestibular stimulation entails coactivation of other sensory receptors. The use of fMRI is challenging as the strong
