Recycling of brake pads is a tough but promising work considering the current end of lifecycle. This study assesses the environmental performance of brake pads made up of recycled friction materials in terms of energy use, CO2 footprint and airborne particle number. Energy use and CO2 footprint are calculated with the data from CES Edupack and airborne emission particle number is measured on a pin
Reliable prediction tools are yet to be developed for estimating the accurate acoustic performance of lightweight structures, which are vital especially in the design process. This paper presents a sound insulation prediction model based on artificial Neural Networks (NN) to estimate acoustic performance for airborne and impact sound insulation of floor structures. At an initial stage, the predict
Background: In patients with chronic obstructive pulmonary disease (COPD), the relationship between short-term bronchodilator reversibility and longer-term response to bronchodilators is unclear. Here, we investigated whether the efficacy of long-acting bronchodilators is associated with reversibility of airflow limitation in patients with COPD with a low exacerbation risk not receiving inhaled co
Background: Mitral valve (MV) and tricuspid valve (TV) apparatus geometry are essential to define mechanisms and etiologies of regurgitation and to inform surgical or transcatheter interventions. Given the increasing use of cardiovascular magnetic resonance (CMR) for the evaluation of valvular heart disease, we aimed to establish CMR-derived age- and sex-specific reference values for mitral annula
Degradation of extracellular matrix, is a prerequisite for processes like tumor invasion and angiogenesis. Numerous studies indicate that plasminogen activation, initiated by u-PA, is a key process in malignant tumor growth. The expression of u-PA as well as its receptor is increased in malignant ovarian tumors. Additionally, u-PA stimulates signal transduction leading to cell proliferation and mi
Adaptive and flexible approaches based on implementing different measures as new information emerges have been proposed as a way of enabling robustness towards uncertain future climate change. However, the success of flexible approaches in practice depends on the stability of the relevant organizational landscapes. In this paper, we draw upon key insights from the institutional theories of organiz
The brain simulates the world around us using sensory information and provides an estimation of reality in which actions can be executed. This estimation of reality is controlled by attention which decides which information is accepted, further processed and ignored. The process of attending a certain part of the sensory information while ignoring other parts is called selective attention. I have
The attachment of the 2,2′-bipyridine (bpy) moieties to the surface of planar silicon(111) (photo)electrodes was investigated usingab initiosimulations performed on a new cluster model for methyl-terminated silicon. Density functional theory (B3LYP) with implicit solvation techniques indicated that adventitious chlorine atoms, when present in the organic linker backbone, led to instability at very
Aims: Alexithymia has been linked to cardiovascular disease. The aim was to explore whether the immuno-inflammatory variables galectin-3 binding protein (Gal3BP), soluble (s)CD163 and galectin-3 were independently associated with alexithymia, while controlling for known risk factors for cardiovascular disease, such as depression, anxiety, impaired glycemic control, obesity, smoking, and physical i
A (polysaccharide-rich) waste stream derived from a combined starch and ethanol factory was investigated regarding hydrolysis of the nonstarch carbohydrates for ethanol production. The material was characterized and processed to yield the maximum amount of sugars. The starch fraction was hydrolyzed with amylolytic enzymes, and the resulting fibrous material was separated by filtration. This materi
BACKGROUND: Infections caused by Chlamydia pneumoniae are considered to participate in inflammatory processes leading to coronary artery disease. After a primary infection, the bacteria remain dormant intracellularly causing a chronic inflammatory stimulus. MATERIALS AND METHODS: Blood samples were obtained from 235 patients with acute myocardial infarction (AMI) and 108 patients with unstable ang
Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be
Konceptet att sågtandande polyper kan leda till kolorektal cancer är relativt nytt. Sågtandade polyper orsakar upp till en tredjedel av all sporadisk kolorektal cancer. Trots detta är kunskaperna om sågtandade polypers etiologi, incidens, prevalens och naturalförlopp ofullständiga. Sågtandade polyper är svåra att identifiera och ta bort endoskopiskt. Endoskopister och patologer måste ha kunska
Background/aim: People with profound cognitive disabilities are not expected to learn powered mobility use. The Driving to Learn project focussed on what this population could achieve from practising in a joystick-operated powered wheelchair. By means of using grounded theory methodology an eight-phase process 'growing consciousness of joystick-use' was identified. In addition, a tool for assessme
The presence of various mechanisms of non-genetic inheritance is one of the main problems for current evolutionary theory according to several critics. Sufficient empirical and conceptual reasons exist to take this claim seriously, but there is little consensus on the implications of multiple inheritance systems for evolutionary processes. Here we use the Price Equation as a starting point for a d
An eight-channel, 1 ns bin-size, 23 b dynamic range, single-chip, multihit, time-to-digital converter (TDC) is presented in this paper. A new architecture mixing two previous TDC realizations has been adopted. The chip can execute common-start or common-stop operations on the trailing, leading, or both transitions of the input channels; it stores at least 32 events/channel with a double-hit resolu
In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. The time resolution is sufficient for investigating the dynamics of adsorption and desorption in systems of this
Accessibility in public outdoor environments is an important issue for persons with reduced functional capacity, for example older persons, and is also crucial for older pedestrians’ safety. The aim of the paper is to evaluate the importance and satisfaction of accessibility issues in public outdoor environments the year around as perceived by older persons (65 years old and above). Within two bef
BACKGROUND: There has been a growing body of evidence associating consumption of ultra-processed foods (UPF) with adverse health outcomes including depression, cardiovascular disease, all-cause mortality. However, whether UPF are associated with dementia is unknown. The authors investigated the associations between UPF and dementia incidence in UK biobank.METHODS: We included 72,083 participants (
