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
(2012)Very few efficient bonding agents for use in solid rocket propellants with nitramine filler materials and energetic binder systems are currently available. In this work, we report the synthesis, detailed characterization, ... -
Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) 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 ... -
On the Use of Computational Fluid Dynamics to Investigate Aerosol Dispersion in an Industrial Environment: A Case Study
(2012)Aerosol dispersion in the area surrounding an existing biological treatment facility is investigated using large-eddy simulation, with the objective to investigate the applicability of computational fluid dynamics to complex ... -
Bandwidth optimizations for standards-based publish/subscribe in disadvantaged grids
(2012)NATO has identified Web services as a key enabler for its network enabled capability. Web services facilitate interoperability, easy integration and use of commercial off-the-shelf components, and while request/response-based ... -
A connectionless multicast protocol for MANETs
(2012)In this paper, the connectionless multicast routing MCOM (Multipoint relay Connectionless Multicast) is introduced for mobile Ad hoc networks. MCOM adapts over a wide ranges of density of group members. It appears as unicast ... -
Adapting OLSR for WSNs (iOLSR) Using Locally Increasing Intervals
(2012)Proactive link state routing protocols, popular within the Mobile Ad hoc NETwork framework, have not been as successful in wireless sensor networks. This is mainly due to the extensive energy usage by control traffic ... -
Chirped pulses sum frequency generation for deep-UV picosecond pulse shaping
(2012)We show by experiments and simulations that properly chirped laser pulses enable efficient and broadband sum frequency generation in nonlinear crystals. We achieved high energy, picosecond deep-UV pulses with spectral ... -
Deletion of the γ-aminobutyric acid transporter 2 (GAT2 and SLC6A13) gene in mice leads to changes in liver and brain taurine contents
(2012)The GABA transporters (GAT1, GAT2, GAT3, and BGT1) have mostly been discussed in relation to their potential roles in controlling the action of transmitter GABA in the nervous system. We have generated the first mice lacking ... -
A survey of the polar cap density based on Cluster EFW probe measurements: Solar wind and solar irradiation dependence
(2012)The plasma density above the Earth's polar caps provide crucial information about the state of the magnetosphere. This region of space is known for its tenuous plasma and extremely low plasma densities, thus making traditional ... -
Improved discretisation and linearisation of active tension in strongly coupled cardiac electro-mechanics simulations
(2012)Mathematical models of cardiac electro-mechanics typically consist of three tightly coupled parts: systems of ordinary differential equations describing electro-chemical reactions and cross-bridge dynamics in the muscle ... -
