Understanding patterns of colonisation is important for explaining both the distribution of single species and anticipating how ecosystems may respond to global warming. Insular flora may be especially vulnerable because oceans represent severe dispersal barriers. Here we analyse two lake sediment cores from Iceland for ancient sedimentary DNA to infer patterns of colonisation and Holocene vegetation ...

Introduction - In the spring of 2014, there was an outbreak of Yersinia enterocolitica (YE) gastroenteritis in four Norwegian military camps—the largest outbreak ever reported in Norway. YE is usually transmitted via food, and the gastrointestinal disease caused by the bacterium is considered a public health problem in several countries. Common symptoms of YE gastroenteritis are abdominal pain, ...

Now is a good time to reflect on the way food tourism could contribute to a better future. A number of scholars comment on the COVID-19 crisis as an opportunity to re-think tourism in terms of sustainability, social and ecological justice (e.g. Gössling, Scott, & Hall, 2020; Higgins-Desbiolles, 2020). Most considerations tend to focus on recovery strategies, challenges of over-tourism and highcarbon ...

Denne afhandling undersøger hvilke type etniske stereotyper, der spiller en rolle i folks hverdagsliv i Grønland i dag; hvilke forventninger, der er fra grønlandsk perspektiv, for at tilhøre den grønlandske eller den danske etniske gruppe samt hvilke kulturelle forskelle, der kunne medføre misforståelser, der har afsæt fra en anden måde at tænke på. Det værende, for eksempel, en individualistisk og ...

This thesis is a discussion of the data that arose out of the ethnographic fieldwork I conducted over the summer of 2018 in Finland. I took part in discussions and practices at various locations in the the Finnish forest about engaging with nature in particular ways, some of which I will present in this paper. These interactions have played a role in furthering my understanding of my research ...

This thesis is intended to contribute to research in cold climate engineering. Further it intends to provide a principle solution for structural and avalanche safety due to snowfall on roofs. We have conducted a feasibility study of preventing snow from accumulating on roofs using airflows. This includes empirical, numerical and experimental methods. Snow loads on roofs makes great impact on ...

Bridge safety is an indispensable part of transportation safety. However, each bridge is unique with respect to its material, design and the environment which it is located in, and other relevant factors. This makes defining a unified framework for studying and categorizing failures in the bridges a difficult task. The current report aims at taking the first step to reach such a goal. This report ...

Background and aims - Many patients with prior intracerebral haemorrhage have indications for antithrombotic treatment with antiplatelet or anticoagulant drugs for prevention of ischaemic events, but it is uncertain whether such treatment is beneficial after intracerebral haemorrhage. STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage will assess (i) the effects of long-term antithrombotic ...

Background: It has been proposed that irritable bowel syndrome (IBS) is a low-grade mucosal inflammatory disease. <p> <p>Objective: To characterize the intestinal inflammatory profile in IBS patients with or without fructose intolerance.<p> <p>Design: Patients referred to colonoscopy with IBS complaints were screened for participation. IBS patients diagnosed according to the Rome II criteria ...
