Behavioral changes following PCB 153 exposure in the Spontaneously Hypertensive rat - an animal model of Attention-Deficit/Hyperactivity disorder
(2014)Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a behavioral disorder affecting 3-5% of children. Although ADHD is highly heritable, environmental factors like exposure during early development to various ... -
Behavioral side effects of prophylactic therapies against soman-induced seizures and lethality in rats
(2014)Four medical therapies previously shown to exert varying degrees of protection against a convulsant dose of soman were assessed for potential behavioral side effects in a novelty test. In Experiment 1, HI-6 (1-[([4-(amin ... -
Spin scan tomographic array-based imager
(2014)This work presents a novel imaging device based on tomographic reconstruction. Similar in certain aspects to the earlier presented tomographic scanning (TOSCA) principle, it provides several important enhancements. The ... -
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 ... -
Trace determination of primary nerve agent degradation products in aqueous soil extracts by on-line solid phase extraction-liquid chromatography-mass spectrometry using ZrO2 for enrichment
(2014)A method for determination of the primary nerve agent degradation products ethyl-, isopropyl-, isobutyl-, cyclohexyl- and pinacolyl methylphosphonic acid in aqueous soil extracts has been developed utilizing on-line solid ... -
Seismic exploration noise reduction in the marginal ice zone
(2014)A sonobuoy field was deployed in the Marginal Ice Zone of the Fram Strait in June 2011 to study the spatial variability of ambient noise. High noise levels observed at 10–200 Hz are attributed to distant (1400 km range) ... -
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. ... -
Improved active sonar tactical support by through-the-sensor estimation of acoustic seabed properties
(2014)Accurate environmental information is required for obtaining confident sonar performance predictions. This environmental information is, however, often unreliable or unavailable. To support antisubmarine warfare (ASW) ... -
Is it Possible to Increase the Share of Military Women in the Norwegian Armed Forces?
(2014)Ever since Norway introduced general conscription for men in 1897, the participation of women in the Norwegian Armed Forces (NorAF) has been an issue for discussion. In 1984 the NorAF introduced occupational equality ... -
Strain rate dependency and fragmentation pattern of expanding warheads
(2014-12-22)For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and ductility at high strain rates, around 104 e105 /s. The flyer plate impact testing ... -
Simulation of natural fragmentation of rings cut from warheads
(2015)Natural fragmentation of warheads that detonates causes the casing of the warhead to split into various sized fragments through shear or radial fractures depending on the toughness, density, and grain size of the material. ... -
The effect of contrast in camouflage patterns on detectability by human observers and CAMAELEON
(2015)Evaluation of signature properties of military equipment is very important. It is crucial to apply the proper method out of many possible approaches, based on amongst others ranking by probability of detection, detection ... -
The Multivariate Normal Inverse Gaussian distribution: EM-estimation and analysis of synthetic aperture sonar data
(2015)The heavy-tailed Multivariate Normal Inverse Gaussian (MNIG) distribution is a recent variance-mean mixture of a multivariate Gaussian with a univariate inverse Gaussian distribution. Due to the complexity of the ... -
Heirs of Zarqawi or Saddam? The Relationship between al-Qaida in Iraq and the Islamic State
(2015)This paper examines the relationship between al-Qaida in Iraq and Islamic State, asking what remains of AQI within the current incarnation of IS. The study is based on available information concerning the backgrounds and ... -
Federated single sign on in disconnected, intermittent and limited (DIL) networks
(2015)In a military setting resource exchange amongst coalition partners is of great importance. Using SAML2.0 in a Single Sign On scheme in a federated setting can be a solution to Web authentication of Web resources. The problem ... -
A concept approach to input/output logic
(2015)This paper provides a semantics for input/input output logic based on formal concept analysis. The central result shows that an input/output logic axiomatised by a relation R is the same as the logic induced by deriving ... -
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 ... -
The final destination: building test bed apps for DIL environments
(2015)Recent years have seen a massive growth in the everyday use of smartphones and tablet (here called smart mobile devices or SMDs) and a turn towards app based software to connect to cloud based services. This has had a huge ... -
