The development of improved biomass pyrolysis models is vital for more accurate modelling and design of biomass conversion equipment. Such improved models must be based on reliable experimental data: biomass should be pyrolyzed at high heating rates and the reaction products should be measured using an on-line, non-intrusive method. Therefore, a heated grid reactor with heating rate of 300-600 K/s

Preeclampsia is one of the most serious pregnancy-related diseases and clinically manifests as hypertension and proteinuria after 20 gestational weeks. The worldwide prevalence is 3-8% of pregnancies, making it the most common cause of maternal and fetal morbidity and mortality. Preeclampsia lacks an effective therapy, and the only "cure" is delivery. We have previously shown that increased synthe

Ecosystem productivity is influenced by the start and end of the growing season, and ecosystem models that simulate productivity need reliable representations of the phenology. For the seasonal development, autumn events are less understood than spring events, with comparatively fewer modelling attempts have been made for leaf senescence than for budburst. The few existing models for autumn phenol

Purpose of review In the modern transfusion service, analysis of the ABO allele underlying a donor or recipient's A or B subtype phenotype is becoming a mainstream adjunct to the serological investigation. Although an analysis of the ABO gene can be helpful in establishing the nature of the subtype phenotype, numerous confounding factors exist that can lead to a discrepancy between the genotype an

The influence of soil pH on the phospholipid fatty acid (PLFA) composition of the microbial community was investigated along the Hoosfield acid strip, Rothamsted Research, UK - a uniform pH gradient between pH 8.3 and 4.5. The influence of soil pH on the total concentration of PLFAs was not significant, while biomass estimated using substrate induced respiration decreased by about 25%. However, th

Doctoral dissertation Abstract Background The relation between mental illness and accountability, may at its best be described as unclear. A negative correlation them between was established thousands of years ago, and has since formed a more or less self-evident supposition. This dissertation is an effort to test this construction. Aims and hypothesis The overall aim of this thesis is to cla

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
