New approaches to evacuation modelling for fire safety engineering applications
This paper presents the findings of the workshop “New approaches to evacuation modelling”, which took place on the 11th of June 2017 in Lund (Sweden)within the Symposium of the International Association for Fire Safety Science (IAFSS). The workshop gathered international experts in the field of fire evacuation modelling from 19 different countries and was designed to build a dialogue between the f

Batch and Continuous Flow Production of 5-Hydroxymethylfurfural from a High Concentration of Fructose Using an Acidic Ion Exchange Catalyst
5-Hydroxymethylfurfural (HMF), a product of catalytic dehydration of C6 sugars, is a versatile and key renewable platform chemical. The possibility to use a high substrate concentration with high yield in a single-solvent system is one of the solutions to reduce solvent usage, energy consumption, reaction volume, and operating cost. A heterogeneous catalyst and single-solvent system were employed
Att beskriva det som syns men inte sägs : Om syntolkning
Syntolkning erbjuder personer med synnedsättning och blindhet en rikare upplevelse av exempelvis film och gör det lättare för användare att förstå och leva sig in i vad som händer. Syntolkens främsta uppgift är att beskriva det som syns men inte hörs. Bidraget fokuserar på syntolkning av en narrativ filmscen ur ett produktionsperspektiv (hur syntolkar gör) och receptionsperspektiv (hur syntolkning
Red-Shifted Photoluminescence from Crystal Edges Due to Carrier Redistribution and Reabsorption in Lead Triiodide Perovskites
Photoluminescence (PL) of CH 3 NH 3 PbI 3 perovskites depends strongly on sample preparation, atmosphere, crystal size, and so forth. However, the origin of these dependencies is always misunderstood because of the co-works of many different factors. Herein, we prepared hexagonal-shaped single crystals with tens of micrometers in size and observed a red-shifted PL emission (800-830 nm) mainly
14.7% Efficiency Organic Photovoltaic Cells Enabled by Active Materials with a Large Electrostatic Potential Difference
Although significant improvements have been achieved for organic photovoltaic cells (OPVs), the top-performing devices still show power conversion efficiencies far behind those of commercialized solar cells. One of the main reasons is the large driving force required for separating electron-hole pairs. Here, we demonstrate an efficiency of 14.7% in the single-junction OPV by using a new polymer do
Bayesian model selection with fractional Brownian motion
We implement Bayesian model selection and parameter estimation for the case of fractional Brownian motion with measurement noise and a constant drift. The approach is tested on artificial trajectories and shown to make estimates that match well with the underlying true parameters, while for model selection the approach has a preference for simple models when the trajectories are finite. The approa
Two-photon excitation spectroscopy of 1,5–Diphenyl-1,3,5-hexatriene using phase modulation
We have used two-photon Fourier transform spectroscopy to investigate the first singlet excited state (S1) of a prototypical polyene molecule 1,5—Diphenyl-1,3,5-hexatriene. As the S1 state in the polyenes is a one-photon forbidden transition, the structure of its vibrational levels cannot be studied using resonant linear excitation. Although this level is accessible with two-photon excitation, pre

Stratigraphy and geothermal assessment of Mesozoic sandstone reservoirs in the Öresund Basin - exemplified by well data and seismic profiles
The Øresund Basin in the transnational area between Sweden and Denmark forms a marginal part of the Danish Basin. The structural outline and stratigraphy of the Mesozoic succession is described, and a novel interpretation and description of the subsurface geology and geothermal potential in the North Sjælland Half-graben is presented. The subsurface bedrock in the basin includes several Mesozoic i
The circular RNome of primary breast cancer
Circular RNAs (circRNAs) are a class of RNAs that is under increasing scrutiny, although their functional roles are debated. We analyzed RNA-seq data of 348 primary breast cancers and developed a method to identify circRNAs that does not rely on unmapped reads or known splice junctions. We identified 95,843 circRNAs, of which 20,441 were found recurrently. Of the circRNAs that match exon boundarie
Fysisk aktivitet ökar muskelstyrkan och minskar antalet fall
En av de mest växande medicinska problemen i samhället är den allt ökande frakturfrekvensen i befolkningen. Vilka individer som drabbas av en frakturberor på ett samspel mellan en rad olika faktorer som benmassan, skelettarkitekturen, muskelstyrkan, muskelfunktionen, balansen och falltendensen. Det har övertygande visats att fysisk aktivitet kan påverka en rad av dessa riskfaktorer för fraktur. Ök
