The red-sky enigma over Svalbard in December 2002
(2005)On 6 December 2002, during winter darkness, an extraordinary event occurred in the sky, as viewed from Longyearbyen (78° N, 15° E), Svalbard, Norway. At 07:30 UT the southeast sky was surprisingly lit up in a deep red ... -
Redrawing borders, reshaping orders: Russia’s quest for dominance in the Black Sea region
(2021-01-04)Since Russia’s annexation of Crimea in March 2014, severe limitations have been placed on Ukraine’s coastal state rights and navigational freedoms in the Black and Azov Seas and the Kerch Strait. The "Kerch Strait clash" ... -
Reducing scalloping in synthetic aperture radar images using a composite image transform
(2015)In burst mode SAR imaging, echo intensity depends on the target's azimuth position in the antenna pattern. As a result, an amplitude modulation known as scalloping may appear, particularly in ScanSAR images of ocean ... -
Regulation of CCN1 (Cyr61) in a porcine model of intestinal ischemia/reperfusion
(2015)Intestinal ischemia is a serious condition that may lead to both local and systemic inflammatory responses. Restoration of blood supply (reperfusion) to ischemic tissues often increases the extent of the tissue injury. ... -
Relative Heading Estimation for Pedestrians Based on the Gravity Vector
(2021-03-15)Inertial navigation of pedestrians carrying a smart device is a core component of many indoor positioning systems. While infrastructure-based solutions typically depend on an installation of dedicated hardware, inertial ... -
A reluctant European: How Norway responds to the EU's quest for strategic autonomy
(2022-11-09)The development of the EU as an actor in the field of security and defence is a challenge for Norway. Being a NATO member, but outside the EU, Norway offers an interesting case study of how a non-member adapts to the growing ... -
Resilient internetwork routing over heterogeneous mobile military networks
(2015)Mobile networks in the military tactical domain, include a range of radio networks with very diverse characteristics and which may be employed differently from operation to operation. When interconnecting networks with ... -
Response of circulating immune cells to major gunshot injury, haemorrhage, and acute surgery
(2005)Purpose: The purpose of this study was to use an established porcine model to investigate the effects on immune function of severe gunshot injury. Methods: Twelve pigs sustained two standardised rounds, one through ... -
Responses of male sperm whales (Physeter macrocephalus) to killer whale sounds: implications for anti-predator strategies
(2013)Interactions between individuals of different cetacean species are often observed in the wild. Killer whales (Orcinus orca) can be potential predators of many other cetaceans, and the interception of their vocalizations ... -
Responsible Research and Innovation Associated With Risk Communication and Public Engagement on Health Emergency Preparedness at the Local Level
(2022-04-05)Responsible Research and Innovation (RRI) associated with public health emergency preparedness (PHEP) and response pose major challenges to the scientific community and civil society because a multistakeholder and ... -
Results of a Ka Band Campaign for the Characterisation of Propagation Conditions for SatCom Systems at High Latitudes
(2017)Satellite services in the High North are utilized extensively for both communication purposes and for earth and climate observations. This paper presents results of two year measurements at 20 GHz and co-sited meteorological ... -
Review and analysis of the explosion accident in Drevja, Norway: A consequence of fire in a mobile explosives manufacturing unit (MEMU) carrying precursors for the on-site production of bulk explosives
(2017)On 17 December 2013, in Drevja, Nordland county, Norway, an uncontrollable fire in a mobile explosives manufactory unit (MEMU) carrying ammonium nitrate-based products and gassing agents for the on-site production of bulk ... -
