Analysis of accelerants by gas chromatography-mass spectrometry and cyclic voltammetry for biosensor development
… of topics, covering fire scene examination, accelerants and present accelerant detection techniques, biosensors, the human olfactory system and electrochemical analytical techniques such as cyclic voltammetry. An overview of all these areas allows a theory to be brought together, that a …

Forensic sample analysis using supercritical fluid extraction coupled with solid phase microextraction
… examination of fire debris for the presence of accelerants are also carried out. PAH could easily be extracted from complex matrices to give recoveries of up to 97% for some analytes at the optimized conditions of 90°C at 4500 psi over a 10 minute dynamic extraction period. Pesticide extraction …

Desarrollo de métodos de caracterización de activadores en incendios
… (intentionally or accidentally). In arson, accelerants such as ignitable liquids are commonly used to initiate or accelerate a fire. The detection of ignitable liquid residues at fire scenes is therefore a key step in fire investigations. The most widely used analytical technique for the …

Braving the swarm : lowering anticipated group bias in integrated fire/police units facing paramilitary terrorism
… enemy combines small-arms with explosives or accelerants, causing extensive fires and smoke conditions, further endangering victims or hostages. To continue its position as a lead innovator in the national fire service, the FDNY must create new strategies and collaborations to frame its …

The degradation of all-dielectric self supporting cables installed in high potential electro-magnetic fields.: A theoretical and practical evaluation of optical fibre cables strung independently on overhead power transmission lines
… previously not quantified, degradation accelerants. The work classifies these accelerants into extrinsic installation and intrinsic product factors.<br/><br/>The thesis presents and reviews the implication of the electrical degradation resistance of sheaths applied to slotted-core and …

Colorimetric sensor arrays with a pre-oxidation method for gaseous analytes
… unburned substrates with the selected different accelerants and the burned residues with selected different accelerants can be detected and well discriminated with our array with the pre-oxidation technique. This work demonstrated that our technology can be used for quality control of automotive …

Absorbent Household Materials For The Collection Of Ignitable Liquid Residues From Surfaces Of Varying Porosity
<p>Ignitable liquids (ILs) are used as accelerants to burn items at a faster rate and the presence of an IL indicates that arson has occurred. Upon arrival to an arson scene, fire investigators access the scene and collect substrates containing ILs. The substrates, such as concrete and wood, are …

Mechanism of SPS acceleration in a PEG containing copper plating bath
… organic compounds, which act as suppressors and accelerants to copper electroplating solutions. The focus of this study is on the acceleration effect of bis-(3-sodiumsulfopropyl) disulfide (SPS) which is believed to go through an electrochemical reaction to form sodium …

Effects of Aquatic Exercise on Executive Function in the Aging Population
… research focused on determining causes, accelerants, impeding factors, and preventative strategies has become a focus of interest within the field. One of the principal points of study is the role that exercise plays in the maintenance or fortification against neurocognitive decline. …

Detection of gasoline from internal tissues for use in determining victim status at the time of a fire
In Ontario, fire investigators from the Office of the Fire Marshal (OFM) are responsible for determining the origin and cause of suspicious fires. As part of the investigation, fire debris samples are collected from the scene and analyzed by the Centre of Forensic Sciences. The standard practice is …
