It has been long recognised that dispersal is an important life-history trait that plays a key role in the demography and evolution of populations and species. This then suggests that dispersal play a central role in the response of populations and species to ever-increasing global change, including climate change, habitat loss and fragmentation, and biological invasions. During a symposium held a

In this thesis, a computational fluid dynamics (CFD) approach is used to study turbulent premixed and partially premixed combustion. The CFD approach is based on large eddy simulation (LES) in which the large-scale structures of the flow are resolved on a grid, leaving only the small-scale structures (subgrid scales) to be modeled. The combustion modelling is based on the flamelet concept in which

Chaos in the chaos research: Reply to Stig Welinder, who commented in META 1989: 4 on the article Jes Wienberg, "Kaos i tiden", META 1989: 3

The successful planning, design and management of a traffic system is impossible without knowledge of how the traffic environment affects the behaviour of road users and how the behaviour is related to the main qualities of the traffic system (e.g. safety, efficiency). Automated video analysis is a promising tool for traffic behaviour research in that it enables collection of micro-level behaviour

OBJECTIVE: To investigate the recently defined Positive and Negative Syndrome Scale for Schizophrenia remission criteria in a naturalistic setting of psychotic patients; to identify causal factors that change remission status; and to validate the criteria against global indices of illness, cognitive functions, and social outcome. METHODS: This was a longitudinal naturalistic study of 162 patients,

BACKGROUND: Thylakoid-stabilised emulsions have been reported to possess satiety-promoting effects and inhibit pancreatic lipase-colipase activity in vitro, which prompted the investigation of their interfacial properties.RESULTS: Thylakoid membranes isolated from spinach were used as an emulsifier/stabiliser in oil (triglyceride)-in-water emulsions. Emulsions were characterised with respect to dr

Adjunctive treatment with hyperbaric oxygen therapy has recently been shown to improve ulcer healing in patients with chronic diabetic foot ulcer. The aim of the present study is to evaluate whether hyperbaric oxygen therapy improves the health related quality of life in these patients.

Objective: Bone loss and periosteal expansion is found after menopause. The accelerated early postmenopausal bone loss is not permanent but if the same accounts for the periosteal expansion is unknown. Methods: Bone mineral density (BMD) and skeletal structure of the distal forearm were followed from menopause and on average 24 years (range 18-28) by single-photon absorptiometry at 12 occasions in

OBJECTIVE. We re-evaluated a cohort of patients referred for reflux symptoms and objectively diagnosed with pathological reflux, with the purpose of clarifying the course of conservatively treated gastroesophageal reflux disease (GERD). MATERIAL AND METHODS. All consecutive patients with GERD diagnosed between 1984 and 1988 showing pathologic 24-h pH-metry in the interval 3.8-10% and without any p

Natural radiative lifetimes of 20 levels (energy range between 20 000 35 000 cm(-1)) in Cd II and 5 levels (energy range between 43 000-49 000 cm(-1)) in Gd III have been measured using time-resolved laser-induced fluorescence III a laser-produced plasma.
