Popular Abstract in Swedish Hållfastheten hos en balk av konstruktionsvirke är beroende av balkens spännvidd och typ av belastning. En längre balk har en lägre hållfasthet än en kort balk på samma sätt som en balk med konstant moment har lägre hållfasthet än en balk belastad med en punktlast. Orsaken till denna längd- och lastberoende bärförmåga är variationen i hållfasthet längs med en balk. VariThe load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber. This variability is, in turn, due to the presence of knots, the slope of grain a

Tidigare var den största anledningen till restriktivitet med träning hos gravida rädslan för förhöjd temperatur. Kroppstemperaturen stiger dock inte hos gravida vid upp till submaximal träning på grund av förbättrad temperaturreglering. Det paradoxala fenomenet att kroppstemperaturen sjunker samtidigt som kvinnan känner sig varmare och svettas lättare, tolkar vi som en förbättrad temperaturregleri

The kinetics of a catalyst for hydrocarbon-selective catalytic reduction (HC-SCR) exhaust aftertreatment has been examined by means of transient experiments on a heavy-duty diesel engine rig. The influences of temperature, NO2 concentration, and the transient injection of hydrocarbon on the conversion of NO,, CO, and hydrocarbon were studied in a systematic manner. Hydrocarbon conversion was high

The present work is a contribution to the study of Christian Arabic literature. An apologetic treatise on the unity and trinity of God incorrectly attributed to Yahya ibn Adi (d. 974) is edited for the very first time and provided with a comprehensive word index. The edition is based on six manuscripts found in Egypt. Four of these manuscripts have so far not been known to scholarly research. The

The ion channel-forming peptide AlaM (alamethicin) is known to permeabilize isolated mitochondria as well as animal cells. When intact tobacco (Nicotiana tabacum L.) Bright Yellow-2 cells were treated with AlaM, the cells became permeable for low-molecular-mass molecules as shown by induced leakage of NAD(P)(+). After the addition of cofactors and substrates, activities of cytosolic as well as mit

Popular Abstract in Swedish Sjukgymnaster har behandlat patienter i samband med kirurgisk behandling sedan början på 1900-talet och den dominerande uppgiften har varit att förebygga lungkomplikationer och blodproppar samt att bedöma behovet av vidare rehabilitering efter utskrivning. Den medicinska utvecklingen går emellertid snabbt framåt och sjukgymnasten har en utmanande uppgift i att utveckla The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible. It was shown that an airflow of 42.5

In the present work we report data from experiments comparing the proliferative stimuli demonstrated by Streptococcal Protein-G and Staphylococcal Protein A on human peripheral blood mononuclear cells. Protein-G and Protein-A are presented to the cells in solution as well as linked to plastic or Sepharose beads, or incorporated within the cell wall of whole bacteria. The cellular response is measu

We devise a stochastic and spatially explicit model for the dynamics of the initials cells in a stratified shoot apical meristem (SAM). The meristem is composed of three layers with seven initials per layer. We investigate the probability and number of divisions for a mutant lineage to either reach fixation or becoming purged through selection or drift. In contrast to previous studies our results

The mechanisms underlying biphasic insulin secretion have not been completely elucidated. We compared the pattern of plasma insulin changes during hyperglycemic clamps in mice to that of glucose-induced insulin secretion and cytosolic calcium concentration ([Ca2+](c)) changes in perifused mouse islets. Anesthetized mice were infused with glucose to clamp blood glucose at 8.5 (baseline), 11.1, 16.7
