Modelling polar bear maternity den habitat in east Svalbard
, 2020 We evaluated a novel tool that predicts possible maternity den habitat of the polar bear (Ursus maritimus) based on a physical snow transport model, a digital terrain model and weather data.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
AGU AdvancesWith its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole

Polar bears observed climbing steep slopes to graze on scurvy grass in Svalbard
, 2017 It is well known that polar bears feed on vegetation. Here, I report novel observations of polar bears grazing on polar scurvy grass (Cochlearia groenlandica) at the foot of a large seabird colony on a cliff on Spitsbergen, Svalbard, in the summers of ...

On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022
Western countries responded to the full-scale Russian attack on Ukraine on 24 February 2022 by imposing strong sanctions to isolate Russia. Norway has adhered to this policy, with exceptions for cooperation on border control, search and rescue, and ...

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

On the seasonal components of polar motion
Geophysical Research Letters, 1989 The excitation functions for the seasonal components (annual and semiannual) of polar motion are calculated based on the atmospheric antisymmetric Rossby‐Haurwitz wave (1;−3). The meridional structures of geopotential and horizontal wind of this wave are reasonable approximations of the quasi‐standing seasonally varying Rossby waves propagating within ...
