Fire performance of selected IT-equipment

The results from a series of large scale tests are presented to establish the fire performance of a number of common pieces of IT equipment including: computer monitors, printers and CPUs. The monitors have been tested in a fully furnished scenario in the ISO 9705 room arranged in a typical bedroom setting and in a specially constructed 4 m × 5 m room arranged in a typical classroom setting. The o

A life-cycle assessment (LCA) model for cables based on the fire-LCA model

A novel life-cycle assessment (LCA) model has been developed for the investigation of the environmental impact of the choice of material in cable production. In the first application polyolefin based material and PVC material is used. In both cases equivalent fire behaviour is assumed and a fire model is established based on existing fire statistics. This study represents the second full applicati

Fire-LCA study of TV sets with VO and HB enclosure material

A novel Life-Cycle Assessment model (Fire-LCA) has been defined for the determination of the environmental impact of measures taken to attain a high level of fire safety. This study, which represents the first application of this LCA model, concentrates on a comparison between a TV with an enclosure manufactured with a flame retardant (FR) plastic (V0-rated high impact polystyrene, HIPS, typical f

Salinity mitigates cadmium-induced phytotoxicity in quinoa (Chenopodium quinoa Willd.) by limiting the Cd uptake and improved responses to oxidative stress : implications for phytoremediation

Cadmium (Cd) contamination and soil salinity are the main environmental issues reducing crop productivity. This study aimed to examine the combined effects of salinity (NaCl) and Cd on the physiological and biochemical attributes of quinoa (Chenopodium quinoa Willd.). For this purpose, 30-day-old plants of quinoa genotype “Puno” were transplanted in Hoagland's nutrient solution containing diverse

Association between hilliness and walking speed in community-dwelling older Japanese adults : A cross-sectional study: Hilliness and slow walking speed

Purpose: This cross-sectional study investigated the association between hilliness and walking speed in community-dwelling older adults, and whether it varied according to their car-driving status. Methods: Data were collected from 590 participants aged 65 and older living in Okinoshima Town, Shimane prefecture, Japan, in 2018. Comfortable walking speed (m/s) was objectively assessed. Hilliness wa

Detection of Brief Episodes of Atrial Fibrillation Based on Electrocardiomatrix and Convolutional Neural Network

Background: Brief episodes of atrial fibrillation (AF) may evolve into longer AF episodes increasing the chances of thrombus formation, stroke, and death. Classical methods for AF detection investigate rhythm irregularity or P-wave absence in the ECG, while deep learning approaches profit from the availability of annotated ECG databases to learn discriminatory features linked to different diagnosi

Bioplastic accumulates antibiotic and metal resistance genes in coastal marine sediments

The oceans are increasingly polluted with plastic debris, and several studies have implicated plastic as a reservoir for antibiotic resistance genes and a potential vector for antibiotic-resistant bacteria. Bioplastic is widely regarded as an environmentally friendly replacement to conventional petroleum-based plastic, but the effects of bioplastic pollution on marine environments remain largely u

Role of GDF-15, YKL-40 and MMP 9 in patients with end-stage kidney disease : focus on sex-specific associations with vascular outcomes and all-cause mortality

Background: Sex differences are underappreciated in the current understanding of cardiovascular disease (CVD) in association with chronic kidney disease (CKD). A hallmark of CKD is vascular aging that is characterised, amongst others, by; systemic inflammation, microbiota disbalance, oxidative stress, and vascular calcification—features linked to atherosclerosis/arteriosclerosis development. Thus,

Chronic Pain and Assessment of Pain Sensitivity in Patients With Axial Spondyloarthritis : Results From the SPARTAKUS Cohort

OBJECTIVE: To study differences in pain reports between patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA), and to assess how pain sensitivity measures associate with disease and health outcomes.METHODS: Consecutive patients with axial SpA (axSpA) were enrolled in the population-based SPARTAKUS cohort (2015-2017) and classified as AS (n = 120) or nr-ax

The influence of “scale-free” networks in the 1 sonata

This article will discuss the influence of scale-free networks on my 1 sonata (Sélection, 5th Dutilleux International Composition Compétition, 2003) for piano. An important feature of scale-free networks is that they are regulated by a small number of important nodes/hubs that are connected to many other sites. Following a power law distribution, research has found that a majority of nodes have on

Quantitative multi-parametric MRI measurements

Quantitative multi-parametric MRI measurements provide reproducible metrics of the MR properties of water to characterize brain tissue. The available parameters are determined by the acquisition protocols. These commonly utilize multiple spin-echo sequences, steady-state sequences of gradient-recalled echoes at variable flip angles or echo-planar images, besides novel non-repetitive acquisitions.

Towards robust glucose chemical exchange saturation transfer imaging in humans at 3 T: Arterial input function measurements and the effects of infusion time

Dynamic glucose-enhanced (DGE) magnetic resonance imaging (MRI) has shown potential for tumor imaging using D-glucose as a biodegradable contrast agent. The DGE signal change is small at 3 T (around 1 and accurate detection is hampered by motion. The intravenous D-glucose injection is associated with transient side effects that can indirectly generate subject movements. In this study, the aim was

A multiphonic harmonic on vibraphone (pedagogy - video)

This video presents what seems to be an unreported multiphonic harmonic on the vibraphone. For the vibraphone, a common technique in contemporary literature features the isolation and production of a single harmonic (h04) in the lower octave. However, through experiments by Olaf Tzschoppe (DE) and Michael Edgerton (SE) on the vibraphone, an unreported multiphonic was found on the lowest thirteen b
