Temporal variability of the bioaerosol background at a subway station: Concentration level, size distribution, and diversity of airborne bacteria
(2014)Naturally occurring bioaerosol environments may present a challenge to biological detection-identification-monitoring (BIODIM) systems aiming at rapid and reliable warning of bioterrorism incidents. One way to improve the ... -
Comparative testing and evaluation of nine different air samplers: End-to-end sampling efficiencies as specific performance measurements for bioaerosol applications
(2014)Accurate exposure assessments are needed to evaluate health hazards caused by airborne microorganisms and require air samplers that efficiently capture representative samples. This highlights the need for samplers with ... -
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 ... -
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. ... -
Minute-scale period oscillations of the magnetosphere
(2011)Oscillations with periods on the order of 5–10 min have been observed by instrumented spacecrafts in the Earth's magnetosphere. These oscillations often follow sudden impacts related to coronal mass ejections. It is ... -
Time-lapse imaging of human heart motion with switched array UWB radar
(2014)Radar systems for detection of human heartbeats have mostly been single-channel systems with limited spatial resolution. In this paper, a radar system for ultra-wideband (UWB) imaging of the human heart is presented. To ... -
XML and Web services security standards
(2009)XML and Web services are widely used in current distributed systems. The security of the XML based communication, and the Web services themselves, is of great importance to the overall security of these systems. Furthermore, ... -
Exploring Network Organization in Military Contexts: Effects of Flatter Structure and More Decentralized Processes
(2011)Changes in the tasks and responsibilities of military organizations in recent decades have prompted new organizational solutions collectively known as network organization. Network organization includes changes to central ... -
Russian defense spending after 2010: the interplay of personal, domestic, and foreign policy interests
(2017)Since 2010, Russia’s defense spending has seen an average annual real growth of 10%, causing a profound shift in the composition of government expenditure. This article examines the formal and informal processes through ... -
Optical parametric master oscillator and power amplifier for efficient conversion of high-energy pulses with high beam quality
(2004)We describe a system for parametric conversion of high-energy, Q-switched laser pulses from 1.064 µm to 2.1 µm in KTiOPO4. High beam quality and efficiency are obtained by use of a two-stage system: An optical parametric ... -
Comparison of two methods for automatic range alignment in ISAR imaging
(2011)A maximum likelihood algorithm for translational motion estimation (TME) in ISAR imaging is described and compared with prominent point processing (PPP). It is suggested that the kurtosis (fourth order central moment) of ... -
Traffic flow confidentiality in federated networks - Multi-topology routing and security options
(2014)Traffic Flow Confidentiality (TFC) aims to prevent analysis of traffic flows. According to the principles of Protected Core Networking (PCN), TFC should be provided as a service in the network and not implemented by the ... -
High thresholds for avoidance of sonar by free-ranging long-finned pilot whales (Globicephala melas)
(2014)The potential effects of exposing marine mammals to military sonar is a current concern. Dose–response relationships are useful for predicting potential environmental impacts of specific operations. To reveal behavioral ... -
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 ... -
Framtiden for russisk verneplikt
(2010)Russia is currently implementing the most comprehensive reform of its Armed Forces since the 1920s – «the Serdiukov reforms». Conscription will be maintained at the same time as important parts of the Armed Forces will be ... -
The Dalton quantum chemistry program system
(2014)Dalton is a powerful general-purpose program system for the study of molecular electronic structure at the Hartree–Fock, Kohn–Sham, multiconfigurational self-consistent-field, Møller–Plesset, configuration-interaction, and ... -
Post-blast explosive residue-a review of formation and dispersion theories and experimental research
(2014)The presence of undetonated explosive residues following high order detonations is not uncommon, however the mechanism of their formation, or survival, is unknown. The existence of these residues impacts on various scenarios, ...
