Purpose: The vast majority of previous studies suggest that there is no relationship between the acceptable noise level (ANL) and pure-tone hearing thresholds reported as the average pure-tone hearing thresholds (pure-tone average). This study aims to explore (a) the relationship between hearing thresholds at individual frequencies and the ANL and (b) a measure of the slope of the audiogram and AN
In the near future, the number of connected mobile devices and data-rates are expected to dramatically increase. Demands exceed the capability of the currently deployed (4G) wireless communication systems. Development of 5G systems is aiming for higher data-rates, better coverage, backward compatibility, and conforming with “green communication” to lower energy consumption. Massive Multiple-Input
Rett syndrome (RTT) is a rare neurodevelopmental disorder usually affecting females. It is associated with intellectual and multiple disabilities leading to a high level of dependency in all aspects of daily living including participation in physical activities. This study explored facilitators and barriers to “uptime” (non-sedentary) activities in Danish girls and women with RTT as perceived by p
Background: In stage I/II natural killer (NK)/T-cell lymphoma, concurrent chemoradiotherapy (CCRT) had previously been shown to result in superior outcome compared with anthracycline-containing regimens, which have since been considered ineffective. The role of CCRT in comparison with approaches employing nonanthracycline-containing chemotherapy (CT) and sequential radiotherapy (RT) in such patien
Background: Seasonal variation in glucose metabolism might be driven by changes in daylight. Melatonin entrains circadian regulation and is directly associated with daylight. The relationship between melatonin receptor 1B gene variants with glycemic traits and type 2 diabetes is well established. We studied if daylight length was associated with glycemic traits and if it modified the relationship
Ion-beam thermography (IBT) is used to determine the chemical composition of atmospheric aerosols. The aerosols are analyZed by a combination of four ion-beam techniques PIXE, PESA, pNRA and cPESA during thermography. These techniques monitor the concentrations of the available elements during the stepwise heating of the sample. For each element a thermogram, i.e., the concentration vs. temperatur
The measurement of potential enzymatic activities has been proposed as an efficient method to infer nutrient limitations for microorganisms in environmental samples. To validate this use, confirmation with direct methods of microbial growth responses to resource additions are required. We experimentally manipulated nutrient-poor soils from the afromontane subtropics with relatively low (grassland
An estimation model which uses the gross heat release data and the fuel energy to estimate the total amount of emissions and unburned Hydro Carbon (HC) is developed. Gross heat release data is calculated from a self-tuned heat release method which uses in-cylinder pressure data for computing the energy released during combustion. The method takes all heat and mass losses into account. The method e
Bullous pemphigoid (BP) is an autoimmune bullous disease, associated with autoantibodies directed against the hemidesmosomal components BP180 and BP230. In this study for the first time different laboratories have analyzed the autoantibody profile in the same group of 49 prospectively recruited BP patients. The results show that: 1) disease severity and activity correlated with levels of IgG again
BACKGROUND: The proteasome system plays an important role in synaptic plasticity. Induction and maintenance of long term potentiation is directly dependent on selective targeting of proteins for proteasomal degradation. The 20S proteasome activator PA28αβ activates hydrolysis of small nonubiquitinated peptides and possesses protective functions upon oxidative stress and proteinopathy. The effect o
In five primary hip arthroplasties and in six revisions with impacted, morselized allografts and cement, roentgen stereophotogrammetric analysis (RSA) was planned to be used to measure the subsidence of the polished and double-tapered Exeter femoral stem, relative both to the cement and the femur. Only in two primary arthroplasties and in two revisions could the tantalum markers be adequately imag
Particulate methane monooxygenase (pMMO) is one of the few enzymes that can activate methane. The metal content of this enzyme has been highly controversial, with suggestions of a dinuclear Fe site or mono-, di-, or trinuclear Cu sites. Crystal structures have shown a mono- or dinuclear Cu site, but the resolution was low and the geometry of the dinuclear site unusual. We have employed quantum ref
OBJECTIVES: To analyze the initial clinical and radiological findings, the surgical treatment, and the clinical outcome following surgical decompression in patients with space-occupying bilateral cerebellar infarction.MATERIALS AND METHODS: Ten patients with expansive bilateral cerebellar infarction and decreased level of consciousness were operated with suboccipital craniectomy, removal of the in
Importance: The increasing burden due to cancer and other noncommunicable diseases poses a threat to human development, which has resulted in global political commitments reflected in the Sustainable Development Goals as well as the World Health Organization (WHO) Global Action Plan on Non-Communicable Diseases. To determine if these commitments have resulted in improved cancer control, quantitati
Transition-metal ion doping has been demonstrated to be effective for tuning the photoluminescence properties of perovskite quantum dots (QDs). However, it would inevitably introduce defects in the lattice. As the Mn concentration increases, the Mn dopant photoluminescence quantum yield (PLQY) first increases and then decreases. Herein the influence of the dopant and the defect states on the photo
In 2015, LIBER commissioned the “Working group on Research and Education”. The goal was to collect best practices in library support to both education and research, in part by examining user survey data. As a first step the group started a European LibQUAL consortium, which was evaluated in 2016. As a second step, a survey sent to all 301 European LIBER university libraries asking questions pertai
