Background and purpose Increased intradiscal pressure and relative segmental hypermobility are in vitro observations supporting the idea of increased postoperative load being a reason for progressive degeneration of the free mobile segment adjacent to a lumbar fusion. These mechanisms have been difficult to confirm in clinical studies, and an alternative theory claims instead that the adjacent seg

BACKGROUND: Those who die by suicide and suffer from depression are known to have made more suicide attempts during their life-span as compared to other people with depression. A behavioural sensitisation or kindling model has been proposed for suicidal behaviour, in accordance with a sensitisation model of depressive episodes. The aim of the present study was to test such a model by investigating

Metabolic and psychiatric disturbances occur early on in the clinical manifestation of Huntington's disease (HD), a neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin (HTT) gene. Hypothalamus has emerged as an important site of pathology and alterations in this area and its neuroendocrine circuits may play a role in causing early non-motor symptoms and signs in HD. Lepti

This paper describes and analyses the political discourse regarding e-government (including terms earlier used) in Sweden in the period from the 1960s until today, drawing on a review of policy documents. It is found that even though both the meanings ascribed to computers, the political visions,and the main arguments have changed considerably over time, the majorplans for action have always remai

Promotion of new media industry has become a significant focus for regional development strategies, as it is generally believed that new media industry is a highly desirable form of economic activity. But is this really so? The question was put to a group of international researchers. The article which summarises their discussion and policy recommendations states that it is by no means clear that

Follicular dendritic cells (FDCs) are the antigen (Ag)-trapping accessory cells of the germinal centres (GCs), essential for the development of humoral immune responses and memory. FDCs reside in the microenvironment of secondary lymphoid tissue where Ag-activated B cells expand, and undergo isotype switching and affinity maturation prior to becoming memory B cells. In addition to delivering Ag, F

Popular Abstract in Swedish I Män, våld och moralarbete uppmärksammas hur män, som frivilligt sökt sig till verksamheter där det erbjuds behandling för våld i nära relationer, rapporterar om sina erfarenheter. Rapporteringarna består dels av svar på frågeformulär, dels genom deltagande i samtalsintervjuer. Författaren analyserar hur männen förklarar sina handlingar och gestaltar återberättade erfaMen, violence and moral work- Reports from help-seeking men at treatment centers working with violence in close relationships Men’s violence against women is an extensive social problem. In the 1970s, a new kind of centers were established in the US and UK, focusing on treating men who had been violent against their wives or girlfriends, the aim which is to end the men’s violent behavior. In the

OBJECTIVE: To study how the choice of national EQ-5D tariff may affect utility and incremental quality-adjusted life-year (QALY) estimates. METHODS: South Swedish rheumatoid arthritis patients in an observational study, starting and continuing anti-tumour necrosis factor (TNF) monotherapy (n=54) or anti-TNF plus methotrexate (n=215) for 1 year during May 2002 to April 2009, were included. EQ-5D q

By pulse modulating or deflecting a CW dye laser beam, cascade-free lifetime determinations at high spectral resolution can be performed with the decayed-coincidence technique using measuring times of about 1 minute. The method is illustrated by lifetime measurements for the 72P3/21/2 levels of cesium.

Abstract in German Das Messen von Beschleunigungen und Höhen während einer Achterbahnfahrt bietet die Möglichkeit, den Physikunterricht anwendungsbezogen zu gestalten. Dieser Ansatz erlaubt einen erlebnisorientierten Zugang speziell im Bereich der oftmals als langweilig empfundenen Mechanik. Das Beispiel der Achterbahn Kanonen in Göteborg demonstriert die vielen Möglichkeiten der Datenauswertung.

Planar laser induced fluorescence (LIF) has been utilized for two-dimensional imaging in combustion environments. By using tracer LIF the fuel distribution prior to ignition has been monitored in a GDI-engine. The results obtained were used to determine the influence from various engine parameters such as nozzle type, spray angle, duration of injection, start of injection, piston shape, etc. Two f

One of the obstacles that seem to impede a more frequent application of the modelling and simulation approach system dynamics (SD) in the software engineering community is the lack of well-defined and repeatable procedures for generating or using information that (a) stems from real industrial software development practice and (b) is suitable for SD model building. This problem can be resolved, at
