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 ... -
Deep-ultraviolet picosecond flat-top pulses by chirp-matched sum frequency generation
(2012)Picosecond, flat-top, deep-UV pulses are needed to generate high-brightness electron beams to efficiently drive x-ray free electron lasers. Current metal photocathodes have low efficiency and therefore require high-energy ... -
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 ... -
Inverse scattering of dispersive stratified structures
(2012)We consider the inverse-scattering problem of retrieving the structural parameters of a stratified medium consisting of dispersive materials, given knowledge of the complex reflection coefficient in a finite frequency ... -
Performance of a Multiband Passive Bistatic Radar Processing Scheme - Part II
(2012)Simulations based on real-life FM radio waveforms showed that the algorithm is capable of improving range resolution, and thus the accuracy, according to theory for single scatterers as is summarized. The performance of ... -
An upper-bound metric for characterizing spectral and spatial coregistration errors in spectral imaging
(2012)Coregistration errors in multi- and hyperspectral imaging sensors arise when the spatial sensitivity pattern differs between bands or when the spectral response varies across the field of view, potentially leading to large ... -
Stochastic Analysis of England Grain Prices 1750-1850
(2012)We study the prices of grain in England 1750-1850, with special attention to the Tamboro volcano eruption time period 1815-1820. Two different types of time series are constructed and compared with the historical data. ... -
On the Kinetics of Anaerobic Power
(2012)Background This study investigated two different mathematical models for the kinetics of anaerobic power. Model 1 assumes that the work power is linear with the work rate, while Model 2 assumes a linear relationship ... -
On the Big Bang Cosmology as a Kinematic Event in Newtonian Cosmology Modified by Dark Energy
(2012)The concepts dark matter and dark energy are commonly used to explain the universe. The dark energy can be conceived as a property of vacuum or the ether. However, a quite different but also common approach is to modify ... -
Role of the gerA operon in L-alanine germination of Bacillus licheniformis spores
(2012)Background The genome of Bacillus licheniformis DSM 13 harbours three neighbouring open reading frames showing protein sequence similarities to the proteins encoded from the Bacillus subtilis subsp. subtilis 168 gerA ... -
Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate and shallow diving toothed whales during exposure to naval sonar.
(2012)Naval sonar has been accused of causing whale stranding by a mechanism which increases formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased risk of decompression sickness (DCS), ... -
Demonstration of Comparison Methods for Ocean Model Validation
(2012)In recent years an increasing amount of oceanographic data has become available. This includes observations as well as data from hydrodynamic ocean models. Validation is required for establishing the necessary confidence ...
