Inom ett par år kommer det nya materialforskningscentret ESS, The European Spallation Source, att stå färdigbyggt. Det kommer då vara det mest avancerade forskningsinstitutet i sitt slag och leverera upp till 30 gånger fler neutroner än någon annan neutronkälla i världen. En av de viktigaste komponenterna på ESS är det s.k. strålmålet som består av nästan 7000 bitar av det metalliska grundämnet voThe European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. Each pulse will deposit 357 kJ in the tungsten causing an instantaneous temperature rise of approximately 100 °C, during the 2.86 ms pulse duration. The target is w

A prototype of a surface emissions trap, a new device for reducing emissions of volatile organic compounds and particulate matter from surfaces while allowing evaporation of moisture, was used to improve the indoor air quality of a school building with elevated air concentrations of 2-ethyl-1-hexanol. A clear improvement of the perceived air quality was noticed a few days after the trap had been a

The autoantigen of endomysial antibodies in coeliac disease has been found to be an enzyme, tissue transglutaminase. Zinc inhibits the calcium-dependent activation of this thiol enzyme and also decreases the affinity between transglutaminase and the antibodies. Physiologically, transglutaminases catalyse the formation of bridges between lysine- and glutamine-containing peptides. Theoretically, if

De senaste åren har det blivit tydligt att detaljhandeln av idag måste hantera två förändringstryck: ökande internethandel och hållbarhetshänsyn. Hur fristående fysiska butiker och kedjor hanterar dessa tryck kommer att få avgörande betydelse för deras överlevnad. I detta kapitel argumenteras för att det finns en framtid för den fysiska butiken om miljöhänsyn tas på allvar ihop med de möjligheter

A whole genome scan to map quantitative trait loci (QTL) for persistency of milk yield (PMY), persistency of fat yield (PFY), persistency of protein yield (PPY) and persistency of milk energy yield (PEY) was performed in a granddaughter design in the German Holstein dairy cattle population. The analysis included 16 paternal half-sib families with a total of 872 bulls. The analysis was carried out

Twenty paternal half-sib families of a granddaughter design were genotyped for 265 genetic markers, most of them microsatellites. These were 16 Holstein families, 3 Simmental families, and 1 Brown Swiss family. The number of sires per breed was 872, 170, and 32, respectively. Two-point recombination rates were estimated both jointly for all breeds and each single breed separately. Of 1168 marker i

IMPORTANCE The positron emission tomography (PET) tracer [18F]flortaucipir allows in vivo quantification of paired helical filament tau, a core neuropathological feature of Alzheimer disease (AD), but its diagnostic utility is unclear. OBJECTIVE To examine the discriminative accuracy of [18F]flortaucipir for AD vs non-AD neurodegenerative disorders. DESIGN, SETTING, AND PARTICIPANTS In this cross-

In order to generate high-voltage high-pulsed power, klystron modulators necessarily contain at least one capacitor bank charging structure supplying the energy to be released during the pulse. Conventional charging structures are based on ac/dc front-end units typically based on diode rectifiers combined with power charging structures operated in on/off mode as a second stage, producing prohibiti

Mild haemophilia is defined by factor levels between 0.05 and 0.40 IU/mL and is characterised by traumatic bleeds. Major issues associated with mild haemophilia are that it may not present for many years after birth, and that awareness, even within families, may be low. Methodological problems exist in diagnosis, such as inconsistencies in results obtained from different assays used to measure fac

The starch industry is a key sector of the European food industry with an annual turnover of approx. €4 billion. The production processes in the starch industry are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs). Membrane processes are only rarely used. This presentation will show how membrane processes can be used to optimise

This paper evaluates the utility of the feedback particle filter (FPF) for state estimation of SE(2)-configured dynamics in a real-time context. The filter is implemented in discrete time to fuse gyroscopic-and accelerometer measurements with Ultra-Wideband (UWB) and camera measurements. With this state information, the FPF is compared to other common filters in terms of the estimate mean square e

Membrane processes, antibiotics, enzymes, biofuels and biochemicalsThe end of the 20th century was marked by the start of the third and so far final wave of biotechnology, the so-called white biotechnology, aiming to substitute chemical processes based on C2/C3 chemistry of oil and gas by biotechnological processes. The standard conversion process in biotechnology is fermentation, which is used t

Objective: To describe the design and rationale for the genetic analysis of acute and chronic cerebrovascular neuroimaging phenotypes detected on clinical MRI in patients with acute ischemic stroke (AIS) within the scope of the MRI-GENetics Interface Exploration (MRI-GENIE) study. Methods: MRI-GENIE capitalizes on the existing infrastructure of the Stroke Genetics Network (SiGN). In total, 12 inte

This contribution deals with investigations on enhanced Fischer–Burmeister nonlinear complementarity problem (NCP) functions applied to a rate-dependent laminate-based material model for ferroelectrics. The framework is based on the modelling and parametrisation of the material’s microstructure via laminates together with the respective volume fractions. These volume fractions are treated as inter

It is a human fundamental to desire to be valued, loved and respected - to be significant. Social exclusion induce significance loss which elicits a 'quest for significance' - the search for opportunities to re-gain significance. The present article establishes this relation in a laboratory experiment (N = 71, mean age = 28, SD = 10.42, 65% women, 35% men), showing that socially excluded individua

Anisotropy of gravitational wave (GW) emission results in a net momentum gained by the black hole (BH) merger product, leading to a recoil velocity up to ∼103 km s−1, which may kick it out of a globular cluster (GC). We estimate GW kick retention fractions of merger products assuming different models for BH spin magnitude and orientation. We check how they depend on BH–BH merger time and propertie

The ambition of this two-part article is to argue for immanent critique as a research strategy in sustainability studies. We do this by picking up and developing two central, cross-cutting themes in sustainability research, namely interdisciplinarity and normativity. It is widely suggested that the problem-driven and solution-focused orientation in sustainability studies necessitates interdiscipli

The estimation of dynamic panel data models with interactive effects and moving average errors is considered. This is accomplished by making an extension to the factor analytical (FA) estimator which was originally designed for dynamic panels with fixed effects only and serially uncorrelated errors. The results show that the additional allowances have no effect on the asymptotic properties of the
