Association between hearing status and tinnitus distress

BackgroundDegree of distress perceived due to tinnitus is different in every individual. Underlying mechanisms for this are yet unclear.ObjectiveInvestigating the relationship between hearing status and tinnitus distress.Material and methodsThis is a case-control study. 38 individuals with tinnitus, divided into normal hearing (NHT, n = 19) and hearing impaired (HIT, n = 19) groups. Groups were ag

Increasing climatic sensitivity of global grassland vegetation biomass and species diversity correlates with water availability

Grasslands are key repositories of biodiversity and carbon storage and are heavily impacted by effects of global warming and changes in precipitation regimes. Patterns of grassland dynamics associated with variability in future climate conditions across spatiotemporal scales are yet to be adequately quantified. Here, we performed a global meta-analysis of year and growing season sensitivities of v

Use of measuring tools in practice development projects—A critical perspective

Background: Occupational therapists are generally positive towards use of measuring tools. However, such use may be problematic.Purpose: To illuminate hidden and adverse effects of using measuring tools in occupational therapy.Method: A Foucauldian inspired thematic analysis of the use of measuring tools in 13 reports of practice development projects in Denmark.Findings: Three themes were construcBackground.Occupational therapists are generally positive towards use of measuring tools.

Impacts of long-term land use on terrestrial organic matter input to lakes based on lignin phenols in sediment records from a Swedish forest lake

Organic carbon burial in lake sediments plays an important role in the global carbon cycle, and is heavily affected by the terrestrial organic matter input. However, few studies have focused on long-term changes in terrestrial organic matter input to lakes in response to land-use changes. The aim of this study was to assess variations in sedimentary terrestrial organic matter over the last 1000 ye

Ultraviolet vision aids the detection of nutrient-dense non-signaling plant foods

To expand our understanding of what tasks are particularly helped by UV vision and may justify the costs of focusing high-energy light onto the retina, we used an avian-vision multispectral camera to image diverse vegetated habitats in search of UV contrasts that differ markedly from visible-light contrasts. One UV contrast that stood out as very different from visible-light contrasts was that of

Numerical study of the combustion and application of SNCR for NOx reduction in a lab-scale biomass boiler

In this paper, a numerical study of flow, reactions and NOx emissions from a biomass boiler is presented. Detailed reaction mechanisms for the decomposition of tar species, combustion of hydrocarbons and formation of NOx are employed by adopting appropriate reaction sets from literature. The proposed mechanism is used to perform CFD simulations of a laboratory-scale biomass boiler, and temperature

Analyses of thermal performance and pressure drop in a plate heat exchanger filled with ferrofluids under a magnetic field

This paper experimentally investigates the effect of various magnetic fields on the performance of a plate heat exchanger filled with ferrofluids. Spherical nanoparticles Fe3O4 with an average diameter of 20 nm are dispersed into DI-water to synthesize the ferrofluid. Thermal performance and flow characteristics of the ferrofluid with 0.1% particle concentration are investigated based on various a

Controlled experimentation in continuous experimentation : Knowledge and challenges

Context: Continuous experimentation and A/B testing is an established industry practice that has been researched for more than 10 years. Our aim is to synthesize the conducted research. Objective: We wanted to find the core constituents of a framework for continuous experimentation and the solutions that are applied within the field. Finally, we were interested in the challenges and benefits repor

Impact of climate change on wetland ecosystems : A critical review of experimental wetlands

Climate change is identified as a major threat to wetlands. Altered hydrology and rising temperature can change the biogeochemistry and function of a wetland to the degree that some important services might be turned into disservices. This means that they will, for example, no longer provide a water purification service and adversely they may start to decompose and release nutrients to the surface

Measurement of relative static permittivity and solvatochromic parameters of binary and ternary CO2-expanded green solvents

CO2-expanded liquids (CXLs) is a class of solvent systems giving relatively low viscosity in comparison to neat organic solvents. The challenge is to achieve a high overall polarity of the CXL, despite the presence of compressed liquid CO2. In this study, the relative static permittivity (εr) was measured for binary and ternary one-phase mixtures of CO2 + green solvent using an in-line microfluidi

Dynamics of hydrogen loss and structural changes in pyrolyzing biomass utilizing neutron imaging

We present results from neutron-imaging studies of slow, vacuum pyrolysis of beech, poplar and conifer wood, and pelletized biomass from room temperature up to 1000 °C. A detailed and quantitative method to extract 2D (in situ neutron radiography, NR) and 3D (ex situ neutron computed tomography, NCT) information on structural transformation and elemental hydrogen content has been developed. NCT an

Age impairs mnemonic discrimination of objects more than scenes : A web-based, large-scale approach across the lifespan

Recent findings suggest that the effect of aging on recognition memory is modality-dependent, affecting memory for objects and scenes differently. However, the lifespan trajectory of memory decline in these domains remains unclear. A major challenge for assessing domain-specific trajectories is the need to utilize different types of stimuli for each domain (objects and scenes). We tested the large

Validation of surrogate measures of safety with a focus on bicyclist–motor vehicle interactions

Surrogate measures of safety (SMoS) can enable quick, pro-active, and detailed safety evaluations by studying near-crashes. A critical concern regarding SMoS is their validity. This study focused on the validity of two commonly used SMoS indicators—minimum time to collision and post-encroachment time—with a specific focus on bicyclist–motor vehicle interactions. The study was divided into two main

Integrating risk assessment and business impact assessment in the public crisis management sector

Risk and Vulnerability Assessments (RVAs) are often conducted by public sector organizations to prevent or prepare for hazards and threats. In Sweden, practitioners increasingly adopt approaches that are based on Business Continuity Management (BCM), where Business Impact Assessments (BIA) are used to gain organizational understanding, in favor of more traditional risk assessments. Both processes

Relationship between atrial fibrillatory rate based on analysis of a modified base-apex surface electrocardiogram analysis and the results of transvenous electrical cardioversion in horses with spontaneous atrial fibrillation

Objectives: To compare the atrial fibrillatory rate (AFR) derived from a local right atrial intracardiac recording (RA-FR) and from a single-lead surface electrocardiogram (ECG) during atrial fibrillation (AF) and to evaluate the correlation with transvenous electrical cardioversion (TVEC) threshold (in Joules), number of shocks and cardioversion success rate in horses. Animals: ECGs and clinical
