Download or read book Canines written by Lauryn E. DeGreeff and published by CRC Press. This book was released on 2022-01-31 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection canines have been utilized throughout the world for over a century, and while numerous attempts have been made to replicate the canine’s ability to detect substances by mechanical means, none has been as successful. The olfactory system is a highly intricate and sophisticated design for chemical sensing, and the olfactory capacity of many animals, including canines, is considered unmatched by machine due to not only their great sensitivity and superior selectivity but also their trainability and mobility. These unique features have led to the use of such animals as "whole-animal" biosensors. Amplifying the benefits and diminishing the limitations of detection canines' interdisciplinary research is crucial to understanding canine olfaction and detection and enhancing this powerful and complex detector. The past 50 years have produced vast advancements in animal behavior/training technology to develop canines into more proficient and reliable sensors, while scientific research has provided tremendous support to help practitioners better understand how to utilize this powerful sensor. This book assembles a diverse group of authors with expertise in a variety of fields relating to detection canines and the chemical sensing industry, including both research and operational perspectives on detection canines. It illustrates how science enhances our understanding of how canines are employed for solving some of the world’s leading detection challenges.

Book Synopsis Detection and Characterization of Volatile Organic Compounds from Burned Human and Animal Remains in Fire Debris by : Eimi I. Taormina

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Debris collected from various test sites where mammalian remains (human and porcine) had been burned in a variety of full-scale fire scenarios was evaluated for the presence of volatile residues characteristic of those remains. Levels of light volatiles were measured using the method commonly used for fire debris analysis: gas chromatography-mass spectrometry (GC-MS). Homologous n-aldehydes (n-hexanal, n-heptanal, and n-octanal) proved to be a significant indicator of the presence of burned mammalian tissue as they were observed in nearly all of the samples. The lighter-weight aldehyde, n-hexanal, appeared more frequently than the heavier aldehydes, n-heptanal and n-octanal; such aldehydes are created by the combustion of animal fats. Ethanol was detected in two-thirds of the samples, while acetone appeared in about three-fourths of the samples, but both were detected at much lower concentrations than n-hexanal. There appeared to be no distinction between volatile n-aldehydes produced from burned porcine carcasses and those from human cadavers. However, more in-depth research will be needed to confirm the significance of acetone and ethanol in body-related fire debris analysis and to explore the possible contributions of non-fire decomposition processes. Since the n-aldehydes are not produced by the pyrolysis or combustion of any normally encountered substrate (carpet, bedding, wood products or upholstery), their detection by normal fire debris methods appears to be a reliable indicator of the presence of burned mammalian remains. This data will also provide guidance to fire debris analysts as to the nature of volatiles associated with the combustion of human bodies in real-world fires.

Book Synopsis Soil in Criminal and Environmental Forensics by : Henk Kars
Download or read book Soil in Criminal and Environmental Forensics written by Henk Kars and published by Springer. This book was released on 2016-09-08 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This introductory volume to a new series on Soil Forensics gives a kaleidoscopic view of a developing forensic expertise. Forensic practitioners and academic researchers demonstrate, by their joint contributions, the extent and complexity of soil forensics. their reports exemplify the broad range of sciences and techniques applied in all stages of forensic soil examinations, from investigations at crime scenes to providing evidence that can be used in court proceedings. Moreover the necessity is depicted of co-operation as a condition for any work in soil forensics between scientists of different disciplines, but no less between scientists and law enforcers.Soils play a role in environmental crimes and liability, as trace evidence in criminal investigations and, when searching for and evaluating, buried human remains. This book shows soil forensics as practiced in this legal context, emerging and solidifying in many countries all over the world, differing in some respects because of differences in legal systems but ultimately sharing common grounds.
Book Synopsis Determination of Biogenic Amines in Decomposition Odor Using Gas Chromatography Mass Spectrometry by : Mackenzie Renee Wisor
Download or read book Determination of Biogenic Amines in Decomposition Odor Using Gas Chromatography Mass Spectrometry written by Mackenzie Renee Wisor and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a forensic investigation of missing persons or a suspected murder the detection of the corpse is often the most important piece of evidence. Human remain detection dogs (HRD) are the most common method used in locating human remains. Although these dogs are useful in distinguishing between animal and human remains little is known about how they are able to do this. The HRD dog’s ability to detect human remains depends on volatile organic compounds (VOCs) that are emitted during decomposition. Previous studies reported that a variety of different compounds including acids, alcohols, ketones, sulfides, and nitrogen containing compounds are present in decomposition odor. Although these researchers found a variety of compounds they do not report the presence of biogenic amines like putrescine and cadaverine. These amines are produced during the decomposition process through decarboxylation of amino acids and is responsible for the distinct odor released by decomposing corpses. Our hypothesis is that these biogenic amines are not being detected due to the limitation of the analytical methods used by other researchers. Primary amines often have high basicity, high polarity, and low volatility compared to other VOCs, they tend to absorb and decompose in the GC column, sample vessels, and injection system making them hard to detect in low concentrations and difficult to analyze using GC-MS. To obviate this problem, our goal is to develop an analytical method to analyze these amines by derivatizing them before the introduction into the GC system. Reacting with a suitable derivatization agent these amines can be converted into more volatile and less polar derivatives making analysis by GC-MS a feasible method. Several derivatization methods were used. One was a method that used tetrafluoroacetylacetone (FAA) in a Schiff base reaction and another used pentafluoroproponic anhydride (PFPA) in an acylation reaction and neither produced the results that was desired so a different method was used. The current reaction is formation of carbamates using chloroformates. This reaction is particularly used on primary, secondary, tertiary amines, and is generally less reactive with water. To use a chloroformate derivatizing agent it has to be in a pH controlled environment to complete the reaction. To extract them for analysis via liquid-liquid extraction toluene is used. Isobutyl chloroformate was the specific derivatizing agent used and was chosen for its higher peak response with the derivatives. This has yielded clear and constant data that has indicated that the amines are being derivatized by the isobutyl chloroformate and that they can be detected in the GC-MS reliably. A calibration curve was made to fulfill the second goal of derivatization which is to quantify the amines. This method was also used on various soil samples and pseudo scent products to explore the practical application of this derivatization method. Amines were found in most of the practical samples tested and were quantified.

Book Synopsis Current Concepts in Forensic Entomology by : Jens Amendt
Download or read book Current Concepts in Forensic Entomology written by Jens Amendt and published by Springer Science & Business Media. This book was released on 2010-01-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forensic Entomology deals with the use of insects and other arthropods in medico legal investigations. We are sure that many people know this or a similar definition, maybe even already read a scientific or popular book dealing with this topic. So, do we really need another book on Forensic Entomology? The answer is 13, 29, 31, 38, and 61. These are not some golden bingo numbers, but an excerpt of the increasing amount of annual publications in the current decade dealing with Forensic Entomology. Comparing them with 89 articles which were published d- ing the 1990s it illustrates the growing interest in this very special intersection of Forensic Science and Entomology and clearly underlines the statement: Yes, we need this book because Forensic Entomology is on the move with so many new things happening every year. One of the most attractive features of Forensic Entomology is that it is multid- ciplinary. There is almost no branch in natural science which cannot find its field of activity here. The chapters included in this book highlight this variety of researches and would like to give the impetus for future work, improving the dev- opment of Forensic Entomology, which is clearly needed by the scientific com- nity. On its way to the courtrooms of the world this discipline needs a sound and serious scientific background to receive the acceptance it deserves.

Available in PDF, EPUB and Kindle. Book excerpt: Forensic archaeology is mostly defined as the use ofarchaeological methods and principles within a legal context.However, such a definition only covers one aspect of forensicarchaeology and misses the full potential this discipline has tooffer. This volume is unique in that it contains 57 chapters fromexperienced forensic archaeological practitioners working indifferent countries, intergovernmental organisations orNGO’s. It shows that the practice of forensic archaeologyvaries worldwide as a result of diverse historical, educational,legal and judicial backgrounds. The chapters in this volume will bean invaluable reference to (forensic) archaeologists, forensicanthropologists, humanitarian and human rights workers, forensicscientists, police officers, professionals working in criminaljustice systems and all other individuals who are interested in thepotential forensic archaeology has to offer at scenes of crime orplaces of incident. This volume promotes the development offorensic archaeology worldwide. In addition, it proposes aninterpretative framework that is grounded in archaeological theoryand methodology, integrating affiliated behavioural and forensicsciences.
Book Synopsis Environmental and Criminal Geoforensics by : D. Pirrie
Download or read book Environmental and Criminal Geoforensics written by D. Pirrie and published by Geological Society of London. This book was released on 2013-12-05 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological techniques are widely used in two aspects of serious criminal investigations: (1) the search for clandestine burial sites, based on near-surface geophysics or through the detection of decomposition signals and (2) the analysis of trace evidence to identify its source location or test the possible association between the trace evidence and a known location of an offence. Although geoforensics is used in such investigations world-wide there are still considerable gaps in the published literature. In addition, there is increasing concern regarding the illegal release of wastes either into the atmosphere, water courses or on to the land surface, and a growing realization that the techniques used in criminal forensics are equally useful in the investigation of environmental crime. This book bridges the gap between environmental and criminal geoforensics with conceptual, methodological and case study contributions. This demonstrates the significant potential that geoforensics holds for investigating and regulatory officers.
