(International Mountain Society (IMS) and United Nations University, 2019-10-18)Glacial mountain environments are changing rapidly as a result of climate change and the expansion of nature-based recreation. Anticipatory planning to adapt to such changes is a key management challenge. The aim of this study was to explore how ...

ABO blood group does not impact incidence or outcomes of surgery for acute type A aortic dissection (Informa UK Limited, 2019-10-23)Objectives. To evaluate the distribution and impact of ABO blood groups on postoperative outcomes in patients undergoing surgery for acute type A aortic dissection (ATAAD). Design. A total of 1144 surgical ATAAD patients from eight Nordic centres ...

(Springer Science and Business Media LLC, 2019-01-24)Genome-wide association studies (GWAS) of quantitative electrocardiographic (ECG) traits in large consortia have identified more than 130 loci associated with QT interval, QRS duration, PR interval, and heart rate (RR interval). In the current study, ...

(Elsevier BV, 2019-06)Background: Evidence on associations between occupational diesel exhaust and gasoline exposure and colorectal cancer is limited. We aimed to assess the effect of workplace exposure to diesel exhaust and gasoline on the risk of colorectal cancer. Methods: ...
-
(University of Copenhagen, 2018-09-05)Teachers who encounter difficulties when implementing technology in their classes often hesitate to give it another try. They expect too many technical problems to emerge, reducing time spent on learning mathematics. Still, if a task requires only ...

-
(Elsevier BV, 2019-06)Population movement is a major driver for infectious disease transmission and can impact the success of disease control and elimination strategies. The relationship between disease transmission and permanent migration is well documented, but fewer ...
-
(Cambridge University Press (CUP), 2019-04-11)Mass-balance measurements of Icelandic glaciers are sparse through the 20th century. However, the large archive of stereo images available allows estimates of glacier-wide mass balance in decadal time steps since 1945. Combined with climate records, ...
-
(Oxford University Press (OUP), 2019-03-20)Genomes are dynamic biological units, with processes of gene duplication and loss triggering evolutionary novelty. The mammalian skin provides a remarkable case study on the occurrence of adaptive morphological innovations. Skin sebaceous glands (SGs), ...
-
(Elsevier BV, 2019-06)This work reports identification of muons by their characteristic life-time of 2.20 μs after laser-induction of their precursor mesons, both kaons K± and KL 0 and pions π± in ultra-dense hydrogen H(0). The pair-production signal from scattered muons ...
-
(Wiley, 2019-04-16)Lung cancer as a second primary malignancy (lung-2) is increasingly common, but its prognosis is poorly understood. This study aims to examine the overall and cancer-specific survival of patients diagnosed with lung-2 compared to lung-1. Primary lung ...
