Introduction - Physical harm from Colorectal Cancer Screening tends to be inadequately measured and reported in clinical trials. Also, studies of ongoing Colorectal Cancer Screening programs have found more frequent and severe physical harm from screening procedures, e.g., bleeding and perforation, than reported in previous trials. Therefore, the objectives of the study were to systematically review ...

Objective - Sham acupuncture has been used as a control in acupuncture efficacy trials. However, questions have been raised about whether it is a physiologically inert placebo. We aimed to understand global research trends and provide guidance for future research by conducting a bibliometric analysis of sham acupuncture studies.<p> <p>Methods - Journal articles published to date related to sham ...

The Early Miocene Upper Marine Molasse (OMM) in south-western Germany contains a diverse fossil ecosystem in which elasmobranch teeth are especially abundant. However, the scarcity of outcrops and sometimes poor preservation of fossils resulted in scant recent literature about the OMM. Here, we focus on the elasmobranch fauna to determine the trophic relationships within the OMM, using fossil ...

Arctic tundra vegetation is affected by rapid climatic change and fluctuating herbivore population sizes. Broad-billed geese, after their arrival in spring, feed intensively on belowground rhizomes, thereby disturbing soil, mosses, and vascular plant vegetation. Understanding of how springtime snowmelt patterns drive goose behavior is thus key to better predict the state of Arctic tundra ecosystems. ...

Ruminants are dependent on their gut microbiomes for nutrient extraction from plant diets. However, knowledge about the composition, diversity, function, and spatial structure of gut microbiomes, especially in wild ruminants, is limited, largely because analysis has been restricted to faeces or the rumen. In two geographically separated reindeer subspecies, 16S rRNA gene amplicon sequencing revealed ...

For a ski guide, updating on the ever-changing natural conditions and group dynamics is essential to stay safe and provide a good experience for clients. In this paper, we explore how guides update their understanding in the mountains. Our data arise out of a one-season participant ethnography of ski guiding in Norway. The research team had two authors collecting data, one as an “outsider” and another ...

Background - Comparing the impact of the COVID-19 pandemic on the incidence of newly diagnosed breast tumors and their tumor stage between the Netherlands and Norway will help us understand the effect of differences in governmental and social reactions towards the pandemic.<p< <p>Methods - Women newly diagnosed with breast cancer in 2017–2021 were selected from the Netherlands Cancer Registry and ...

This paper reports a detailed study of the flow in cyclone separators, with the use of most up to date computational fluid dynamics simulations, which are validated with positron emission particle tracking (PEPT) experiments tracing the movement of particles through the cyclone. The parameters varied were the viscosity of the carrier liquid, the flowrate and, in the numerical simulations, the ...

Surfers daring the harshest waves, including the frigid arctic waters of Norway, rely on wetsuits for extended cold-water sessions. Understanding the thermal behavior of wetsuit materials is crucial for enhancing surfers' comfort and safety. In this study, we investigate the thermal properties of neoprene and natural rubber, the primary materials used in wetsuit construction, with a focus on conductive ...

This article attempts to make sense of the speaker in Johann Wolfgang von Goethe’s «Wandrers Nachtlied II» and Rainer Maria Rilke’s «Herbst». It starts from the observation that the utterance in both poems combines a rhetorical function with a space-creating function, and that both functions participate in the poem’s organization as a communicative act in decisive ways. My conclusion is that the ...
