Using the Power Balance Model to Simulate Cross-Country Skiing on Varying Terrain
(2014)The current study adapts the power balance model to simulate cross-country skiing on varying terrain. We assumed that the skier’s locomotive power at a self-chosen pace is a function of speed, which is impacted by friction, ... -
Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
(2014)Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ... -
L-alanine-induced germination in Bacillus licheniformis -the impact of native gerA sequences
(2014)Background L-alanine, acting through the GerA receptor, was recently found to be an efficient germinant in Bacillus licheniformis ATCC14580/DSM13. Results In this study, we show that several of 46 examined B. ... -
Microvesicle Shedding and Lysosomal Repair Fulfill Divergent Cellular Needs during the Repair of Streptolysin O-Induced Plasmalemmal Damage
(2014)Pathogenic bacteria secrete pore-forming toxins that permeabilize the plasma membrane of host cells. Nucleated cells possess protective mechanisms that repair toxin-damaged plasmalemma. Currently two putative repair scenarios ... -
Selected Issues of QoS Provision in Heterogenous Military Networks
(2014)Tactical ad-hoc networks are evolving today towards complex heterogeneous networks in terms of architecture, protocols and security. Due to the difference in network resources and reliability, end-to-end quality of service ... -
A Framework for Authentication in NBD Tactical ad hoc networks
(2011)Network-based defense (NBD) and the all-IP network make authentication ever more important. However, a generally accepted and comprehensive authentication suite is lacking. This work is a step toward filling the gap. The ... -
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 ... -
ELEMENTAL ABUNDANCES IN THE FAST SOLAR WIND EMANATING FROM CHROMOSPHERIC FUNNELS
(2010)We carry out a model study to determine whether a funnel-type flow geometry in the solar wind source region leads to sufficiently fast hydrogen flow to offset heavy element gravitational settling and can thus explain why ... -
Temperature dependent lattice constant of Al0.90Ga0.10AsySb1-y
(2010)Using x-ray diffraction, the in-plane and out-of-plane lattice constants of Al0.90Ga0.10AsySb1−y epilayers grown on GaSb and GaAs substrates were determined between 30 and 398 °C for y = 0.003–0.059. The bulk lattice ... -
The Rise of Muslim Foreign Fighters Islam and the Globalization of Jihad
(2010)Why has transnational war volunteering increased so dramatically in the Muslim world since 1980? Standard explanations, which emphasize U.S.-Saudi support for the 1980s Afghan mujahideen, the growth of Islamism, or the ... -
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 ... -
Neurotoxic effects of perfluoroalkylated compounds: mechanisms of action and environmental relevance
(2012)Perfluoroalkylated compounds (PFCs) are used in fire-fighting foams, treatment of clothes, carpets and leather products, and as lubricants, pesticides, in paints and medicine. Recent developments in chemical analysis have ... -
Heat stress in chemical protective clothing: porosity and vapour resistance
(2011)Heat strain in chemical protective clothing is an important factor in industrial and military practice. Various improvements to the clothing to alleviate strain while maintaining protection have been attempted. More recently, ... -
Wireless power transfer in the presence of metallic plates: Experimental results
(2013)We demonstrate efficient wireless power transfer between two high Q resonators, especially in a complex electromagnetic environment. In the close proximity of metallic plates, the transfer efficiency stays roughly the same ... -
High pulse energy and symmetrical far field from an optical parametric oscillator in the red spectral range
(2011)Red pulses with >30 mJ energy and <0.6 nm bandwidth have been demonstrated using a type 2 phase matched optical parametric oscillator pumped at 532 nm. A symmetrical signal beam with beam diameter-divergence product of ~3 ... -
Ultrawideband Gated Step Frequency Ground-Penetrating Radar
(2012)We describe a prototype ultrawideband radar. We show how the system was designed and how the hardware was developed for the radar prototype. Waveform generation, radar parameters, and signal processing for the stepped ... -
Iron Cannot Fight - The Role of Technology in Current Russian Military Theory
(2011)Contemporary Russian military theory is dominated by three schools of thought: the ‘traditionalists’, the ‘modernists’ and the ‘revolutionaries’. On the role of technology in future warfare, the traditionalists argue for ... -
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 ... -
O and Ne in an H-He Fast Solar Wind
(2011)We have studied the abundances and ion fractions of O and Ne in an H-He fast solar wind with emphasis on gravitational settling in the chromosphere and corona. We use a time-dependent numerical model that spans the mid- ... -
MODELING IRON ABUNDANCE ENHANCEMENTS IN THE SLOW SOLAR WIND
(2011)We have studied the behavior of Fe ions in the slow solar wind, using a fluid model extending from the chromosphere to 1 AU. Emphasis is on elemental "pileup" in the corona, i.e., a region where the Fe density increases ...
