The upgraded version of the GEM side-on thermal neutron detector was successfully tested in a neutron diffraction experiment on a reference sample using the INES diffractometer at the ISIS spallation neutron source, UK. The performance of the new 10B4C-based detector is compared to that of a standard 3He tube, operating at the instrument as a part of the detectors assembly. The results show that t

Dementia is one of the burdensome diseases in older age for which there is no cure known. The demand for carers of dementia patients is growing as the population ages. We analyse serious games as an approach to provide dementia carers with training on care related problem solving and modelling real-world cases. We present the behaviour model of improved care process by applying serious games, desc

Leadership scholars are beginning to understand leadership as a distributed phenomenon, produced in interaction and emerging in social situations. Although this perspective has contributed to understanding leadership processes in more detail, it has also been noted that its proponents have largely neglected power and asymmetrical hierarchical relations. In this paper, I address these issues by dra

The results of a search for new heavy W′ bosons decaying to an electron or muon and a neutrino using proton–proton collision data at a centre-of-mass energy of s=13 TeV are presented. The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 fb-1. As no excess of events above the Standard Model prediction is

Films engineered to control the transport of liquids are widely used through society. Examples include barriers in packaging, wound care products, and controlled release coatings in pharmaceutics. When observed at the macroscopic scale such films commonly appear homogeneous, however, a closer look reveals a complex nano- and microstructure that together with the chemical properties of the differen

The swelling of ionic microgel particles is investigated at a wide range of concentrations using a combination of light, X-ray and neutron scattering techniques. We employ a zero-average contrast approach for small-angle neutron scattering experiments, which enables a direct determination of the form factor at high concentrations. The observed particle size initially decreases strongly with the pa

MoOx/n-CdTe photosensitive heterostructures were prepared by the deposition of molybdenum oxide thin films onto three different n-type CdTe substrates (ρ1=0.4 Ωfirst>cm, ρ2=10 Ωfirst>cm, ρ3=40 Ωfirst>cm) by DC reactive magnetron sputtering. The height of the potential barrier and series resistance of the MoOx/CdTe heterojunctions were investigated. The dominating current transport mechanisms throu

We study thermal equilibrium of classical pointlike counterions confined between symmetrically charged walls at distance d. At very large couplings when the counterion system is in its crystal phase, a harmonic expansion of particle deviations is made around the bilayer positions, with a free lattice parameter determined from a variational approach. For each of the two walls, the harmonic expansio

The parasitoid wasp Neodryinus typhlocybae (Ashmead) was introduced to Europe for the biological control of nearctic planthopper Metcalfa pruinosa (Say), which causes severe damage to both crops and ornamental species in the absence of specialized natural enemies. We performed a series of experiments to evaluate the host instar preference and the effects on parasitoid offspring sex. Results showed

The present study investigates the use of gestures by 18-, 24- and 30-month-old Swedish children, as well as their practical actions in coordination with verbs. Previous research on connections between children’s verbs and gestures has mainly focused only on iconic gestures and action verbs. We expand the research foci in two ways: we look both at gestures and at practical actions, examining how t

Pathogens are one of the main forces driving the evolution and maintenance of the highly polymorphic genes of the vertebrate major histocompatibility complex (MHC). Although MHC proteins are crucial in pathogen recognition, it is still poorly understood how pathogen-mediated selection promotes and maintains MHC diversity, and especially so in host species with highly duplicated MHC genes. Sedge wa

The barrier properties of cellular membranes are increasingly attracting attention as a source of inspiration for designing biomimetic membranes. The broad range of potential technological applications makes the use of lipid and lately also polymeric materials a popular choice for constructing biomimetic membranes, where the barrier properties can be controlled by the composition of the membrane c

Digitala plattformar som erbjuder så kallade Massive Open Online Courses (MOOCs) är sedan några år tillbaka ett fenomen som växt sig gradvis starkare. Moocar har lyfts fram som ett lovande exempel på tillgängliggörandet av universitetsutbildning till en bredare allmänhet och som rätt använt också har potential att nå nya studieovana målgrupper runt om på jorden. Fördelarna till trots, har utveckli

In modernity’s tourism, nature is just a resource. In modernity, enterprises exploit human and natural resources, churning out products to feed the modern desire to consume. In the process, people and nature are carelessly ‘used up’. Thus, Brundtland’s famous exhortation for sustainable development (Brundtland, 1987) remains unheeded, and the rhetoric of sustainable tourism (Bramwell & Lane, 1

Målsättningar för och behov av hållbara transporter i städer är idag ett etablerat område inom trafik- och samhällsplaneringen och ökad cykling har sedan många år varit högt prioriterat av politiker och planerare. Trots dessa ambitioner har cyklingen i stället minskat på många håll under senare år. Det finns alltså ett stort behov av att identifiera och utveckla strategier och åtgärder som främjar
