Different approaches to anion exchange membranes (AEMs) are currently intensively investigated with the aim to develop materials for application in electrochemical energy devices such as alkaline fuel cells and electrolysers.1 One of the major challenges is to identify feasible synthetic strategies to AEM materials with sufficient long-term chemical and thermal stability. Studies of different smal
BACKGROUND AND OBJECTIVES: To study selective regional binding for tau pathology in vivo, using PET with [(11) C]PBB3 in PSP patients, and other conditions not typically associated with tauopathy.METHODS: Dynamic PET scans were obtained for 70 minutes after the bolus injection of [(11) C]PBB3 in 5 PSP subjects, 1 subject with DCTN1 mutation and PSP phenotype, 3 asymptomatic SNCA duplication carrie
The ctaBCDEF genes coding for cytochrome c oxidase were found to reside adjacent to a regulatory gene ctaA at 127-degrees on the Bacillus subtilis chromosome. The structural genes for subunits I and II, ctaD and ctaC, were deleted by gene-replacement using a phleomycin-resistance marker. The mutant was unable to oxidize N,N,N',N'-tetramethyl-p-phenylenediamine and oxidized cytochrome c at a signif
A multiscale modeling framework for polycrystal materials is established, using a combination of an extended vertex model and a crystal plasticity formulation. The 2D vertex model is cast to incorporate a range of mesoscale processes such as grain structure evolution and the influence of second-phase particles. It is combined with a finite strain crystal plasticity formulation whereby also texture
Background Previous viscoelastic haemostatic tests studies have often indicated a hypercoagulative test signal with citrated blood, which could influence clinical decision makings. Purpose The aim of this study was to compare fresh and citrated whole blood using two non-automated viscoelastic ROTEM and Sonoclot tests. Our hypothesis was that citrated blood would demonstrate a hypercoagulative resp
An amperometric immunoanalysis system based on monoclonal antibodies immobilized on Sepharose beads and packed into a micro-immunocolumn was developed for the quantification of microcystin-LR. Microcystin-LR (MCLR) was used as a reference microcystin variant. Inside the immunocolumn, free microcystins and microcystin-horseradish peroxidase (tracer) were sequentially captured by the immobilized ant
S100 protein is a marker for brain damage easily analysed in blood. The serum level immediatly after termination of extracorporeal circulation (ECC) is increased and associated to age and the duration of perfusion. A prolonged residual concentration indicates cellular brain damage. The objective of this study was to ascertain if the prognosis of individual patients, with stroke following ECC, coul
Neurological disorders are among the main clinical problems affecting preterm children and often result in the development of communication and learning disabilities later in life. Several factors are of importance for brain development, however the role of immunoglobulins (passive immunity transfer) has not yet been investigated. Piglets are born agammaglobulinemic, as a result of the lack of tra
We present a dual-wavelength polarimetric measurement method to distinguish species and sexes of disease transmitting mosquitoes in flight. By measuring co- and de-polarized backscattered light at 808 and 1550nm, the degree of linear polarization, wingbeat frequency, reflectance, spectral ratio and glossiness of mosquitoes can be retrieved. Body and wing contributions to these signals can be separ
Conodonts have been a key tool for biostratigraphical, evolutionary and palaeobiogeographical studies, and the GermanicBasin has been one of the most important regions for these studies. However, few modern studies provide systematic data onthe mainly endemic conodonts of the Middle Triassic Germanic Basin. Here we document conodonts from two sections inGermany, one Bithynian in age and the other
A supervisory observer is a multiple-model architecture, which estimates the parameters and the states of nonlinear systems. It consists of a bank of state observers, where each observer is designed for some nominal parameter values sampled in a known parameter set. A selection criterion is used to select a single observer at each time instant, which provides its state estimate and parameter value
Novel Sm2O3−NiO composite was prepared as the functional electrolyte for the first time. The total electrical conductivity of Sm2O3−NiO is 0.38 S cm−1 in H2/air condition at 550 °C. High performance, e.g. 718 mW cm−2, was achieved using Sm2O3−NiO composite as an electrolyte of solid oxide fuel cells operated at 550 °C. The electrical properties and electrochemical performance are strongly depended
Background: As a renewable energy solution, photovoltaics (PVs) are crucial in the transition to a more sustainable energy system. Besides large PV installations, household adoption of PVs will be an important contribution to this transition. However, the adoption of PVs on a household level faces many barriers, with gathering and understanding information being one of the major barriers. The aim
The world has become increasingly telecoupled through distant flows of information, energy, people, organisms, goods, and matter. Recent advances suggest that telecouplings such as trade and species invasion often generate spillover systems with profound effects. To untangle spillover complexity, we make the first attempt to develop a typology of spillover systems based on six criteria: flows from
This thesis deals with epitaxial growth and optical properties of semiconductor nanowires with implications and insights about materials for solar cells. The chapters leading up to the papers give a broader background and an introduction to the field and include nanowires and their synthesis, semiconductor properties, solar cell operational principles, light interaction with a nanowire array, and
