Venous thromboembolism (VTE) is a relatively common cause of morbidity and mortality. It has an annual incidence of around 0.1- 0.3%. It is a multifactorial disease with many known risk factors, both transient and persistent. Among these, several genetic risk factors have been described. The most common genetic risk factor, factor V Leiden mutation in heterozygote form, is found in 5-8% of the Cau
Peatland net ecosystem production is a key variable to assess changes in the functional role of peatlands in the global carbon cycle. Light use efficiency (LUE) models in combination with satellite data have been used to estimate production for most major ecosystems, but peatlands have been largely ignored. The objectives of this study were: 1) to examine how the LUE parameter epsilon, ε (the amou
Recent revisions in the sunspot records illustrate the challenges related to obtaining a 400-year-long observational record of past solar-activity changes. Cosmogenic radionuclides offer the possibility of obtaining an alternative and completely independent record of solar variability. Here, we illustrate that these records offer great potential for quantitative solar-activity reconstructions far
Unveiling the determinants for transferase and hydrolase activity in glycoside hydrolases would allow using their vast diversity for creating novel transglycosylases, thereby unlocking an extensive toolbox for carbohydrate chemists. Three different amino acid substitutions at position 220 of a GH1 β-glucosidase from Thermotoga neapolitana caused an increase of the ratio of transglycosylation to hy
In order to avoid environmental pollution and eliminate the need for using fertiliser, this study assessed for the first time the optimum performance of mature (in operation since 2011) vertical flow constructed wetlands in treating domestic wastewater (with and without hydrocarbon) and the subsequent recycling of the outflow to irrigate chillies (De Cayenne; Capsicum annuum (Linnaeus) Longum Grou
The evaluation of emergency, disaster and crisis management exercises supports both individual and organisational learning, facilitates the development of response capabilities, and helps to determine whether the current level of preparedness is good enough. Nevertheless, despite its importance in the field of disaster risk management, there is a lack of a comprehensive overview of research in the
I denna artikel redogörs för uttorkning hos betong med Byggcement jämfört med andra cementsorter: Slite Std-cement samt anläggningscement. Inverkan av silikastoft på uttorkningen hos Slite Std-cement redovisas. För ändamålet studerades 14 betonger upp till ett halvt år. Inverkan av självuttorkning, lufthärdning och vattenlagring fanns med i programmet. Resultaten visar att uttorkningen i huvudsak
Flight is an economical mode of locomotion, because it is both fast and relatively cheap per unit of distance, enabling birds to migrate long distances and obtain food over large areas. The power required to fly follows a U-shaped function in relation to airspeed, from which context dependent ‘optimal’ flight speeds can be derived. Crosswinds will displace birds away from their intended track unle
I denna artikel redovisas en sammanställning av ett stort antal broprojekt mellan den japanska huvudön Honchu och den söder därom belägna ön Shikoku. Först ges en bakgrund vad gäller andra stora hängbroar och snedkabelbroar i världen. Därefter belyses och specifieras de aktuella japanska broarna i detalj. Sammantaget är brosystemen mellan Honchu och Shikoku imponerande inte bara vad gäller spännvi
