Popular Abstract in Swedish Inom nervsystemet finns det i huvudsak två kontrollsystem: dels det somatomotoriska nervsystemet som reglerar skelettmuskulatur, dels det autonoma nervsystemet som reglerar aktivitet hos hjärta, glatt muskulatur (t.ex. blodkärl och mag-tarmkanalen) och körtlar. ?Autonom? betyder självständig och syftar till att det autonoma nervsystemet (ANS) i huvudsak inte är viljestyRespiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. In the first two studies fear-relevant pictorial s

Since the early 1980s, rapidly internationalizing start-ups have captured attention of the academia, media and institutions. These ’born global’ firms seem to disregard the traditionally established views of firm internationalization. In spite of the significant resource limitations, they manage to reach international markets rapidly and keep their competitive position in the long term, running ag

In this paper an online method for automatically reducing complex chemical mechanisms for simulations of combustion phenomena has been developed. The method is based on the Quasi Steady State Assumption (QSSA). In contrast to previous reduction schemes where chemical species are selected only when they are in steady state throughout the whole process, the present method allows for species to be se

An experiment was performed to investigate the behavior of inclined negatively buoyant jets. Such jets arise when brine is discharged from desalination plants and improved knowledge of their behavior is required for designing discharge systems that cause a minimum of environmental impact on the receiving waters. In the present experiment, a turbulent jet with a specific salinity was discharged t

This chapter addresses the question of the growth of accuracy and complexity in L2 French from the perspective of developmental sequences of morphosyntax, developmental stages and linguistic profiling. We examine the systematic growth of morphosyntactic features expressed by the learner during the acquisition process (sequences). Furthermore, we investigate the relatedness of different development

Sammanfattning I projektet ”Modellering av spårbarhet och riskanalys för säker och hållbar livsmedelsproduktion” har arbetet varit inriktat på hur producenten kan arbeta på ett proaktivt sätt med sin tillverkningsprocess utifrån ett risk- och spårbarhetsperspektiv utifrån försörjningskedjeperspektiv. För att kunna fatta medvetenbeslut kring risk och möjlighetsnivåer för en given produktionslinje h

The molecular mechanisms behind the development and progression of rheumatoid arthritis are not known in fine details. Both humoral and cellular responses against collagen type II in joint cartilage seems to be important for the disease development. Especially posttranslational modifications on collagen type II are important in regulation of molecular mechanisms implicated in the disease. In this

The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. The results were used to investigate the suggestion that the nucleo-olivary pathway is part of a negative feedback system for the

I rapporten redogörs för ett antal arbetstidsmodeller som kan användas vid en arbetstidsförkortning. Modellerna var föregångare till de digitala arbetstimodeller typ Time-care som senare utvecklades. Rapporten är ett resulatat av ett fältarbete som genomfördes tillsammans med SPRI och Stockholms läns landsting.
