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
vilket påverkar hur vi ser på hållbarhetsaspekter vid planering av städer och i förlängningen enskilda bygg- och anläggningsprojekt. Detta medför att bygg- och fastighetsföretags sociala ansvarstagande blir en alltmer relevant del av verksamheten, inte minst vad gäller upphandling av entreprenörer och konsulter där det läggs en större vikt avseende sociala aspekter än tidigare.Trafikverkets upphan
The present study explored presence of meaning in life, search for meaning in life, and their correlation with health anxiety. The Meaning in Life Questionnaire and the Short Health Anxiety Inventory were completed by 753 individuals. Results indicated higher presence of meaning in life was associated with lower health anxiety, while the opposite was observed for search for meaning in life. Result
Purpose/Objective • Behavioral interventions hold enormous promise for managing a variety of motor and nonmotor symptoms in Parkinson's disease (PD). Despite this, prior studies have suggested that the utilization of these interventions is relatively low. The current study seeks to understand factors that could relate to the utilization of PD behavioral strategies. Specifically, the study evaluate
Shifts in hemispheric dominance were previously proposed to play a role in hypnosis. Participants (N = 32) were exposed to an active–alert hypnosis induction and a music-control condition while electrodermal activity was registered bilaterally, providing information on alterations in hemispheric dominance. The results suggest that highly hypnotizable participants show a shift to right-sided and lo
