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

Interstitial laser-induced thermotherapy (ILT) destroys tumors thermally, ILT was performed for treatment of liver tumors in rats to investigate the effect of hepatic inflow occlusion on temperature distribution and lesion size. Tumors were irradiated for 20 min with near-infrared light from a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser, The laser light at a power of 1.5 W was delivered throu

Resultaten från denna studie tyder på att åldrat slaggrus som används utblandat med planteringsjord (här 50 vikt-%), till exempel i sluttäckningsändamål, inte ger upphov till betydande förhöjda metall- och metalloidhalter i engelskt rajgräs under en växtsäsong jämfört med vanliga anläggningsmaterial (här schaktmassa och bergkross). Studien visar även på vikten av att ta hänsyn till damning och

BACKGROUND: Patterns of subsequent malignancies in patients with cancer of unknown primary (CUP) may provide etiological insight into the primary tumor. The objective of the present study is to quantify risks of the subsequent cancers in CUP patients since such studies are lacking. PATIENTS AND METHODS: A population-based cohort of CUP was identified from the Swedish Family-Cancer Database of year

BackgroundThe presence of orthostatic hypotension (OH) predicts all-cause mortality and incident cardiovascular disease. Whether or not OH is associated with the development of heart failure (HF) remains unknown.MethodsIn this Swedish population-based prospective study (the Malmö Preventive Project), the incidence of HF in relation to baseline OH, defined as decrease in systolic (SBP) >/=20 mm Hg

A resolution model for evolutionary conflicts of interest is proposed. We assume that two conflicting parties originally have different evolutionarily stable strategies (ESS) with respect to a continuous variable, but that only one value of the variable is simultaneously possible. Individuals from the two parties meet in antagonistic encounters. The side that invests more in the antagonistic behav

Angiosarcoma is a rare complication of breast cancer treatment. In order to define predictors, clinical presentation, and outcome, we characterized a population-based 50-year cohort of angiosarcomas after breast cancer. Clinical data were collected from all females with previous breast cancer who developed angiosarcomas/lymphangiosarcomas on the thoracic wall/upper extremity between 1958 and 2008

Popular Abstract in Swedish Hantering av avlopp och avfall är en del av alla människors vardag. Vår hälsa och miljö påverkas av metoderna vi tillämpar för att ta hand om rester från hushåll och industrier. Genom teknikens utveckling används idag bakterier i vattenreningsverk där avloppsvatten renas från alla skadliga föremål och föreningar. Med hjälp av matematiska uttryck och analyser, i samspel Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. Mathematical models of biofilms in wastewater are used to understand the underlying processes and to describe and analyze b
