Three experiments were set up to study how drivers estimate mean travel speeds on trips with different speed limits. To specify, participants judged mean speeds of trips with speed limits on different distances of the trip. Study I showed that the mean speed on a road with a temporary 30km/h speed limit was overestimated if the speeds were greater than 80km/h on the rest of the trip. Study 2 repli
The European Standard on sleeping bag requirements (EN 13537:2002) describes a procedure to determine environmental temperature limits for safe usage of sleeping bags regarding their thermal insulation. However, there are several possible sources of error related to this procedure. The main aim of this work was to determine the influence of the various measuring parameters on the acuity of the res
The valence band electronic structure of Pr0.5Sr0.5MnO3 has been investigated across its paramagnetic metallic (PMM)-ferromagnetic metallic (FMM)-antiferromagnetic insulator (AFMI) transition. Using surface sensitive high resolution photoemission we have conclusively demonstrated the presence of a pseudogap of magnitude 80 meV in the near Fermi level electronic spectrum in the PMM and FMM phases a
In this study we have obtained 17 cosmogenic exposure ages from three well-developed moraine systems - Halland Coastal Moraines (HCM), Goteborg Moraine (GM) and Levene Moraine (LM) - which were formed during the last deglaciation in southwest Sweden by the Scandinavian Ice Sheet (SIS). The inferred ages of the inner HCM, GM and LM are 16.7 +/- 1.6, 16.1 +/- 1.4 and 13.6 +/- 1.4 ka, respectively, w
This study explores metabolic responses of germinating barley seeds upon the application of pulsed electric fields (PEE). Malting barley seeds were steeped in aerated water for 24 h and PEF-treated at varying voltages (0 (control), 110, 160, 240, 320, 400 and 480 V). The seeds were then allowed to finish germination in saturated air. It is shown that exposure of germinating barley to PEE affects r
Det har gått nästan sju år sedan dåvarande SOF:s Namnkommitté presenterade ett första utkast till svenska namn på alla världens fågelarter. Efter det att förslagslistan lades ut togs många synpunkter på namnen emot, men därefter gick projektet i stå fram till dess att Taxonomikommittén (Tk) vid sitt möte i september 2013 beslutade att slutföra arbetet.
An inventory of vascular plants in the poorly known forested lowland parts of the provinces of Lule and Torne lappmark has been started. The purpose of the project is to gather distributional data for a forthcoming Swedish atlas of vascular plants. Field work has so far been carried out in the southeastern part of Lule lappmark, from which preliminary results are given.
Abstract in UndeterminedMany species of birds show evidence of secondary contact zones and subspeciation in their Scandinavian distribution range, presumably resulting from different post-glacial recolonization routes. We investigated whether this is the case also in the Scandinavian bluethroat Luscinia svecica, a species that has been suggested to consist of two separate populations: one SW-migra
Abstract in UndeterminedThe two main chromatographic modes based on hydrophobicity, hydrophobic interaction chromatography (HIC) and reversed-phase chromatography (RPC), are widely used for both analytical and preparative chromatography of proteins in the pharmaceutical industry. Despite the extensive application of these separation methods, and the vast amount of studies performed on HIC and RPC
Effects of various enzymes and extraction conditions on yield and molecular weight of beta-glucans extracted from two batches of commercial oat bran produced in Sweden are reported. Hot-water extraction with a thermostable alpha-amylase resulted in an extraction yield of approximate to 76% of the beta-glucans, while the high peak molecular weight was maintained (1.6 x 10(6)). A subsequent protein
Transverse momentum spectra of pi(+/-), K-+/- and p((p) over bar) up to p(T) = 20 GeV/c at mid-rapidity in pp, peripheral (60-80%) and central (0-5%) Pb-Pb collisions at v root s(NN) = 2.76 TeV have been measured using the ALICE detector at the Large Hadron Collider. The proton-to-pion and the kaon-to-pionratios both show a distinct peak at p(T) approximate to 3 GeV/c in central Pb-Pb collisions.
Popular Abstract in Swedish Arktiska ekosystem utgör en viktig del av det globala terrestra utbytet av växthusgaser och energi med atmosfären. I ett klimat som förändras, särskilt uttalat i Arktisk, bör tänkbara framtidsprognoser av växthusgasutbytet från dessa områden övervägas noga när framtida klimat modelleras. En förutsättning för detta är detaljerade studier av nyckelprocesser som påverkar vArctic ecosystems represent an important component in the global terrestrial exchange of greenhouse gases and energy with the atmosphere. In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts. As a prerequisite for this, detailed studies of key processes affe
