The Hotel Payload 2 campaign: Overview of NO, O and electron density measurements in the upper mesosphere and lower thermosphere
(2011)The ALOMAR eARI Hotel Payload 2 (HotPay 2) rocket campaign took place at Andøya Rocket Range, Norway, in January 2008. The rocket was launched on January 31, 2008 at 19:14 UT, when auroral activity appeared after a long ... -
Postnatal exposure to PCB 153 and PCB 180, but not to PCB 52, produces changes in measures of attention, activity level and impulsivity in outbred male Wistar Kyoto rats
(2011)Background Polychlorinated biphenyls (PCBs) are a class of organic compounds that bioaccumulate due to their chemical stability and lipophilic properties. Humans are prenatally exposed via trans-placental transfer, ... -
Increasing the Lifetime of Roadside Sensor Networks Using Edge-Betweenness Clustering
(2011)Wireless Sensor Networks are proven highly successful in many areas, including military and security monitoring. In this paper, we propose a method to use the edge-betweenness community detection algorithm to determine ... -
Clostridium botulinum Group I Strain Genotyping by 15-Locus Multilocus Variable-Number Tandem-Repeat Analysis
(2011)Clostridium botulinum is a taxonomic designation that encompasses a broad variety of spore-forming, Gram-positive bacteria producing the botulinum neurotoxin (BoNT). C. botulinum is the etiologic agent of botulism, a rare ... -
Systemic Chemical Desensitization of Peptidergic Sensory Neurons with Resiniferatoxin Inhibits Experimental Periodontitis
(2011)Background and objective: The immune system is an important player in the pathophysiology of periodontitis. The brain controls immune responses via neural and hormonal pathways, and brain-neuro-endocrine dysregulation ... -
Effects of Cultural Diversity on Trust and its Consequences for Team Processes and Outcomes in Ad Hoc Distributed Teams
(2011)This quasi-experimental study explores trust as a mediator, explaining how cultural diversity may affect team processes and outcomes in distributed ad hoc teams. Data were collected both through self-report and direct ... -
Multiple episodes of fluid flow in the SW Barents Sea (Loppa High) evidenced by gas flares, pockmarks and gas hydrate accumulation
(2012)Gas and gas hydrates have gained considerable attention in the last 20 yr due to their possible impact on global climate change from methane escalations. Our study area, the SW Barents Sea, is unique in its evolution due ... -
Multi-channel and multi-polarisation ship detection
(2012)Norway's large ocean areas in the North require efficient methods to detect vessels in the High North. Radar satellites in orbit today offer dual- or quad-polarised data, which ease the task of detecting vessels in a SAR ... -
Converting the Iranian heavy water reactor IR-40 to a more proliferation-resistant reactor
(2012)This article assesses the feasibility and benefits of converting the Iranian heavy water research reactor, IR-40, from using natural uranium to low-enriched uranium fuel. Based on neutronics calculations for a detailed ... -
Real-time PCR and NASBA for rapid and sensitive detection of Vibrio cholerae in ballast water
(2012)Transport of ballast water is one major factor in the transmission of aquatic organisms, including pathogenic bacteria. The IMO-guidelines of the Convention for the Control and Management of Ships’ Ballast Water and ... -
Turbulence characterization and image processing data sets from a NATO RTO SET 165 trial in Dayton, Ohio, USA
(2012)The performance of optical systems is degraded by atmospheric turbulence. Over propagation distances that exceed several kilometers, it is difficult to evaluate its impact because of terrain variability - a factor that ... -
Behavioral Responses of Captive Herring to Sonar Signals (1-1.6 kHz) of a Naval Frigate Throughout a Yearly Cycle
(2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -
Brutal oppmerksomhet: Al-Qaida i Irak på nett
(2012)Voldelige grupperinger som al-Qaida i Irak benytter seg av internett for å få internasjonal oppmerksomhet. De er imidlertid fortsatt avhengig av en viss grad av territoriell kontroll, og det kan oppstå et motsetningsforhold ... -
Measurements of IR propagation in the marine boundary layer during the September 2011 SQUIRREL trial
(2012)A multinational field trial (SQUIRREL) was performed at the Eckernförder Bucht, in the Baltic Sea, during September 2011 to study infrared ship signature and atmospheric propagation effects close to the sea surface in a ... -
Characterization of airborne bacteria at an underground subway station
(2012)The reliable detection of airborne biological threat agents depends on several factors, including the performance criteria of the detector and its operational environment. One step in improving the detector's performance ... -
Genotyping of B. licheniformis based on a novel multi-locus sequence typing (MLST) scheme
(2012)Background Bacillus licheniformis has for many years been used in the industrial production of enzymes, antibiotics and detergents. However, as a producer of dormant heat-resistant endospores B. licheniformis might ... -
Flow noise reduction from superhydrophobic surfaces
(2012)This work investigates how a highly (super)hydrophobic surface can be used to reduce turbulence-generated drag and noise on a towed streamer cable. The work is done by analyzing full-scale drag and flow noise measurements ... -
Mechanical Properties of Smokeless Composite Rocket Propellants Based on Prilled Ammonium Dinitramide
(2012)Ammonium dinitramide (ADN) is a high performance solid oxidizer of interest for use in high impulse and smokeless composite rocket propellant formulations. While rocket propellants based on ADN may be both efficient, clean ... -
Neutral Polymeric Bonding Agents (NPBA) and Their Use in Smokeless Composite Rocket Propellants Based on HMXGAP- BuNENA
