Although a substantial ice cover has been identified within the mid-latitudes of Mars, there is uncertainty regarding the formation, current and former volume, and dynamic evolution of these ice masses. Here, we present the first comprehensive ice volume estimate of martian glacier-like forms (GLFs) from systematic population scale mapping and volumetric analysis. The outlines of 1243 GLFs were ...

Subarctic permafrost peatlands are important soil organic carbon pools, and improved knowledge about peat properties and peatland sensitivity to past climate change is essential when predicting future response to a warmer climate and associated feedback mechanisms. In this study, Holocene peatland development and permafrost dynamics of four subarctic peat plateaus in Finnmark, northern Norway have ...

The aim of this study was to prepare and optimize a novel type of in situ gel-forming solid dosage form (gfSDF) to be used in the treatment of mucosal/skin ulcerations. For this purpose, a simple but reliable syringe-based hot melt/moulding method was employed. Chloramphenicol (antibiotic) and ibuprofen (anti-inflammatory) were chosen as model active pharmaceutical ingredients (APIs) to be loaded ...

Red cell distribution width (RDW), a measure of variability in size of circulating erythrocytes, is associated with arterial cardiovascular disease (CVD), but the underlying mechanism remains unclear. We aimed to investigate the impact of chronic inflammation as measured by high sensitivity CRP (hs-CRP) on this relationship, and explore whether RDW could be a mediator in the causal pathway between ...

By analyzing a data set from the European Incoherent SCATter (EISCAT) Very High Frequency (VHF) radar at Tromsø, we find that both radar reflectivity and upward ion velocity in a polar mesospheric summer echo (PMSE) layer simultaneously increased at the commencement of a local geomagnetic disturbance, which occurred at midnight on 9 July 2013. The onset of the upward velocity was followed by periodic ...

This article addresses the diachronic development of so-called rival forms, i.e., words or grammatical constructions that appear to be synonyms, based on a detailed empirical analysis of two seemingly synonymous constructions in Russian. Corresponding to the English ‘decade construction’ <i>in the twenties</i>, Russian has two rival constructions, viz. <i>v dvadcatye gody</i> [<i>lit</i>. “in the ...

Background: <br>Contents published on social media have an impact on individuals and on their decision-making. Knowing the sentiment towards diabetes is fundamental to understanding the impact that such information could have on people affected with this health condition and their family members. The objective of this study is to analyze the sentiment expressed in messages on diabetes posted ...

Arctic homeotherms counter challenges at high latitudes using a combination of seasonal adjustments in pelage/plumage, fat deposition and intricate thermoregulatory adaptations. However, there are still gaps in our understanding of their thermal responses to cold, particularly in Arctic birds. Here, we have studied the potential use of local heterothermy (i.e. tissue cooling that can contribute to ...

The Nordmøre grid is regarded as an efficient bycatch reducing device and is used in various shrimp trawl fisheries globally. However, in some shrimp fisheries bycatch remains a problem that seriously impacts commercial trawl activities. This study tested and compared the performance of two versions of the Nordmøre grid in the Northeast Arctic Deepwater Shrimp (Pandalus borealis) fishery; a standard ...

In the laboratory, we investigated which sizes of <i>Nephrops</i> (<i>Nephrops norvegicus</i>) could pass through the meshes of different size and shape to establish a predictive model for the creels size selectivity. Predictions agreed well with the results from experimental fishing, demonstrating the reliability of this simple method. <i>Nephrops</i> minimum target size is 20 mm carapace length ...
