CFD-beräkningar vid brandteknisk dimensionering - En Round Robin studie
Föreningen för Brandteknisk IngenjörsVetenskap (BIV) har genomfört en s.k. Round Robinstudie inom beräkningsområdet CFD. I studien utförde nio deltagande aktörer samma beräkningsuppgifter utan att veta vad de andra kommit fram till. Resultat-sammanställningen visar en relativt stor spridning som till största delen kan förklaras med att deltagarna gör olika ingenjörsmässiga val.De två beräkningsfal

Animated adverts impair children’s online reading and text comprehension
In this study we examined the effects of animated adverts on children’s online reading. We conducted an eye-tracking experiment with authentic web pages to assess whether (1) advert animation primarily affects overt visual attention, or (2) animated adverts primarily affect text comprehension, or (3) both eye movements and comprehension are affected. 59 children in third grade (9-year-olds) partic

Tin-oxide nanoparticles deposited from a beam : what happens to the composition?
The debate around the oxidation states occurring in laboratory-prepared tin-oxide samples has been for a long time an obstacle for an unambiguous assignment of characterization studies performed on such samples. In particular the changes in the Sn core-level energies caused by oxidation - i.e. the chemical shifts - as measured by photoelectron spectroscopy (PES) have been under discussion. The ass
Long-Term, Targeted Delivery of GDNF from Encapsulated Cells Is Neuroprotective and Reduces Seizures in the Pilocarpine Model of Epilepsy
Neurotrophic factors are candidates for treating epilepsy, but their development has been hampered by difficulties in achieving stable and targeted delivery of efficacious concentrations within the desired brain region. We have developed an encapsulated cell technology that overcomes these obstacles by providing a targeted, continuous, de novo synthesized source of high levels of neurotrophic mole
Magnetic body alignment in migratory songbirds : a computer vision approach
Several invertebrate and vertebrate species have been shown to align their body relative to the geomagnetic field. Many hypotheses have been proposed to explain the adaptive significance of magnetic body alignment outside the context of navigation. However, experimental evidence to investigate alternative hypotheses is still limited. We present a new setup to track the preferential body alignment
Lateral episiotomy versus no episiotomy to reduce obstetric anal sphincter injury in vacuum-assisted delivery in nulliparous women : Study protocol on a randomised controlled trial
Introduction Obstetric anal sphincter injury (OASIS) occurs in 5%-7% of normal deliveries and increases with vacuum extraction (VE) to 12%-14% in nulliparous women in Sweden. Lateral/mediolateral episiotomy may reduce the prevalence of OASIS at VE in nulliparous women. The current use of episiotomy is restrictive. The protective effect and consequences are uncertain. This trial will investigate if
Responsive hydrogel colloids : Structure, interactions, phase behavior, and equilibrium and nonequilibrium transitions of microgel dispersions
Soft and responsive colloids based on polymer hydrogels have moved into the focus of the colloid community. This review gives a brief overview of the recent literature on the structure and phase behavior of neutral and ionic poly(N-isopropylacrylamide) microgel dispersions from dilute to over-packed conditions, focusing in particular on the ability of these particles to adapt their size and shape
Combining high-energy X-ray diffraction with Surface Optical Reflectance and Planar Laser Induced Fluorescence for operando catalyst surface characterization
We have combined three techniques, High Energy Surface X-Ray Diffraction (HESXRD), Surface Optical Reflectance, and Planar Laser Induced Fluorescence in an operando study of CO oxidation over a Pd(100) catalyst. We show that these techniques provide useful new insights such as the ability to verify that the finite region being probed by techniques such as HESXRD is representative of the sample sur

Formation of planetary systems by pebble accretion and migration : Growth of gas giants
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract their gaseous envelope. Previously, we have studied the growth and migration of an isolated planet in an evolving disc. Here, we generalise such models to include the mutual gravitational interaction between a high number of growing planetary bodies. We have investigated how the formation of planetary s
