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. ... -
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 ... -
Carbon monoxide (CO) emissions from camping stoves
(2010)Small commercially available camping stoves of four different brands (Optimus, MSR, Coleman and Sigg) were examined for carbon monoxide emission. Without a pot placed onto the stove the carbon monoxide production is very ... -
Card GAP test of Comp A-5
(2008)Comp A-5 pressed to 95.4 %TMD (1.702 g/cm3) has been tested in NOL Card Gap test. The transition between no go and go was found to be 222-3 cards or 56.5 mm. This result indicates that Comp A-5 is relatively shock sensitive ... -
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 ... -
Causes of terrorism : an expanded and updated review of the literature
(2005)This report presents a critical survey of the academic literature on the causes of terrorism. The study focuses primarily on theories that seek to explain why some societies are more exposed to terrorism than others, i.e. ... -
Cavity expansion theory applied to the penetration of high speed spheres into weak targets
(2002)As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the deceleration of spherical steel projectiles in soap has been carried out. Experimental data were compared to numerical ... -
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 ... -
Cetaceans and naval sonar : the 3S-2009 cruise report
(2009)Forsvaret har utrykt behov for å få kartlagt sjøpattedyrs følsomhet overfor sonarsignaler, også atferdsmessige påvirkninger. 3S-konsortiet, som for tiden består av fire partnere, FFI, Woods Hole Oceanographic Institution ... -
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, ... -
Change detection in SAR-images from the TerraSAR-X satellite with main focus towards harbors and container terminals
(2013-10-01)The detection of changes or no change in a set of images of the same scene recorded at different times is of importance in many applications. The time scale could be from seconds to days or months. Man-made constructions ... -
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 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 ...
