Calculation of decomposition products from components of gunpowder by using ReaxFF reactive force field molecular dynamics and thermodynamic calculations of equilibrium composition
(2014)The major combustion products from munitions containing nitro-based propellants are water, carbon monoxide, carbon dioxide, hydrogen and nitrogen. In addition, compounds including hydrogen cyanide, ammonia, methane, nitrogen ... -
Calibration target for extraction of frequency dependency in synthetic aperture sonar
(2019-12-03)Synthetic aperture sonar (SAS) can provide high resolution images of the seafloor backscatter. A current research topic is whether wider bandwidth and lower frequencies can support better discrimination of different ... -
Calprotectin (S100A8/S100A9) and myeloperoxidase: Co-regulators of formation of reactive oxygen species
(2010)Inflammatory mediators trigger polymorphonuclear neutrophils (PMN) to produce reactive oxygen species (ROS: O2-, H2O2, ∙OH). Mediated by myeloperoxidase in PMN, HOCl is formed, detectable in a chemiluminescence (CL) assay. ... -
Can the absolute configuration of cyclic peptides be determined with vibrational circular dichroism?
(2023-05-16)Cyclic peptides show a wide range of biological activities, among others as antibacterial agents. These peptides are often large and flexible with multiple chiral centers. The determination of the stereochemistry of molecules ... -
Capacities of metabotropic glutamate modulators in counteracting soman-induced seizures in rats
(2013)The mechanisms underlying insulin sensitivity and fat tissue distribution in chronic renal insufficiency remain unclear. Previous studies have shown the benefits of angiotensin II receptor blockers on moderately nourished ... -
Cardiovascular and thermal strain during 3–4 days of a metabolically demanding cold‑weather military operation
(2017)Background Cardiovascular (CV) and thermal responses to metabolically demanding multi-day military operations in extreme cold-weather environments are not well described. Characterization of these operations will provide ... -
Cascade dynamics of thermomagnetic avalanches in superconducting films with holes
(2015)The submicrosecond dynamics of thermomagnetic avalanches in superconducting films with nonconducting holes (antidots) is considered. When such an avalanche reaches a hole, it is quickly filled with magnetic flux, and often ... -
CBAM: A Contextual Model for Network Anomaly Detection
(2021)Anomaly-based intrusion detection methods aim to combat the increasing rate of zero-day attacks, however, their success is currently restricted to the detection of high-volume attacks using aggregated traffic features. ... -
CEP-stable few-cycle pulses with more than 190 μJ of energy at 100 kHz from a noncollinear optical parametric amplifier
(2017)Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this ... -
Cerebrospinal Fluid Phosphate in Delirium after Hip Fracture
(2017)Aims: Phosphate is essential for neuronal activity. We aimed to investigate whether delirium is associated with altered phosphate concentrations in cerebrospinal fluid (CSF) and serum. Methods: Seventy-seven patients with ... -
Challenges for Risk and Security Modelling in Enterprise Architecture
(2019-11-19)From our experience cooperating with the Norwegian Armed Forces, we outline two interconnected challenges for modelling risk and security in an enterprise architecture: (1) modelling what is protected and why it is protected ... -
Challenges in Seafloor Imaging and Mapping With Synthetic Aperture Sonar
(2011)Synthetic aperture sonar (SAS) is emerging as an imaging technology that can provide centimeter resolution over hundreds-of-meter range on the seafloor. Although the principle of SAS has been known for more than 30 years, ... -
Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ... -
Change Detection Using Time and Look Angle Series of Geocoded TanDEM-X Staring Spotlight Images
(2021-03-26)This article describes the analysis of changes in time and look angle series of TanDEM-X (TDX) and TerraSAR-X (TSX) staring spotlight images over the regions around Kjeller near Oslo in Norway and the town Nikel in Russia ... -
Changes in dive behavior during sonar exposure in killer whales, pilot whales and sperm whales.
(2012)Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ... -
Changes in fibrinogen availability and utilization in an animal model of traumatic coagulopathy
(2013)Background Impaired haemostasis following shock and tissue trauma is frequently detected in the trauma setting. These changes occur early, and are associated with increased mortality. The mechanism behind trauma-induced ... -
Changes in inoperability for interdependent industry sectors in Norway from 2012 to 2017
(2021-03)The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using ... -
Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress
(2017)The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ...
