Problem statement. Forensic explosive examination - a type of forensic examination, the subject of which is the actual data (circumstances), which are related to determining the group affiliation and a single source of explosive devices as a whole or their fragments (fragments), elements of explosive devices, explosion circumstances are established on the basis of special knowledge in the field of forensic explosives on issues raised for examination. The article is aimed at determining the main factors and causes of fires and explosions during storage, detonation of explosives, as well as provide recommendations for the use of technical means for forensic explosives. The purpose of research. To analyze the main factors and causes of fire and explosion hazard during storage, detonation of explosives, provide recommendations for the use of technical means for judicial explosives, as well as recommendations for storage of explosives. In the course of fire technical examinations and research, the following issues are resolved: where was the source of the fire; the ways in which the flames spread; what is the cause of the fire; whether the Rules of fire safety at the site were violated; whether there is a causal link between the fire and the fire condition of the facility. Conclusions. In the course of explosive examinations and research, the following issues are resolved: what is the subject submitted for research; whether the object submitted for examination is equipped with an explosive; whether the object submitted for research belongs to the category of explosive devices (ammunition); Is the explosive device detonated in this place? If so, what type of device does it belong to (what are its design features, country of manufacture, etc.); whether the objects found at the scene (in the body of the victim) are parts of an explosive device; in what way, improvised or industrial, the explosive device is made; what was the way of undermining, was used in this case; if ammunition is detonated, what type they belong to (grenades, mines, shells, etc.); whether this device can cause an explosion; whether the materials provided to the expert contain data indicating the personality traits of the manufacturer of the explosive device (professional skills, degree of knowledge of the technology of manufacture and use of explosive devices, etc.); or the same design of an improvised explosive device, parts of which were found at the scene, and a model made by a citizen. The analysis of the main factors and causes of danger during storage and detonation of explosives is carried out.

Abstract:
Forensic analysis of explosives includes analysis of post-explosion residues, and detection and identification of traces of explosives on suspects’ hands, on clothing, and on other related items. Preliminary field tests may be used for screening the debris on the explosion site. They include commercially available explosive vapor detectors and chemical color tests. Like post-explosion residues, personal items suspected to contain traces of explosives and hand-swabs, are often heavily contaminated. It is therefore of major importance that the analytical procedures have to include good screening, clean-up, and extraction methods. The main explosives dealt with in this chapter include nitroaromatic explosives, such as 2,4,6-trinitrotoluene (TNT) and 2,4,6, N-tetranitro-N-methyl aniline (tetryl), nitrate esters, such as ethylene glycol dinitrate (EGDN), glycerol trinitrate (nitroglycerin, NG), and pentaerythritol tetranitrate (PETN), and nitramine explosives, such as 1,3,5- trinitro-1,3,5-triazacyclohexane, (RDX) and 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX), as well as mixtures containing one or more of these explosives. Additional explosives include triacetone triperoxide (TATP) and ammonium nitrate (AN), NH4NO3.

Abstract:
Previous analyses of organic peroxide explosives have focussed on identification of the explosive itself, and were performed using explosive samples synthesized from laboratory-grade precursors. In this work, analytical studies of precursors obtained from retail outlets identified compounds that could be carried over into the explosives as impurities during synthesis. Forensic and intelligence information may be gained by the identification of possible precursor impurities in explosive samples. This hypothesis was tested using triacetone triperoxide and hexamethylene triperoxide diamine prepared from domestically available off-the-shelf precursors. Gas chromatography–mass spectrometry analysis showed that compounds originating from such precursors could be detected in the organic peroxide samples at different stages in their purification. Furthermore, some compounds could also be detected in the residues of samples that had been subjected to thermal initiation.

Abstract:
The article is devoted to study of problems of microtraces classification at the general theoretical and scientific forensic level with subsequent extrapolation to microtraces which form a typical trace evidence picture of forensic characteristics in terrorist nature crimes. The analysis of scientific approaches to the definition of microtrace allows us to identify and outline main features typical for this definition, namely: small size; small amount of substances and materials: invisible or faintly visible under normal conditions of observation; peculiarities of their detection, record, seizure and research. The classification of microtraces based on various grounds is provided. Thus, according to organization of matter (form of physical embodiment), microtraces (microparticles) are divided into: single physical formations (individual physical bodies with a stable form); substances (materials) that do not take the from of an individual body (liquids, powdered substances). In accordance with immediate source of origin, micro-objects are classified into two large groups: parts of natural origin (from natural objects); parts separated from objects that are largely processed or man-made. In the first group, four subgroups must be distinguished: microtraces that have separated from the human body; micro-objects from animal; microparticles from plants; micro-objects of mineral nature. When considering micro-objects in conjunction with carrier objects, they are differentiated by a trace-forming object and the type of contact with the carrier: overlay; inclusion; layering. It is noted that the most typical ways of committing terrorist nature crimes are the use of firearms, cold weapons and the use of explosive weapons and / or explosives. Taking into account the fact that manufacture, possession and use of explosive weapons or explosives for the investigation of crimes of this category affects the criminal law qualification, tactics of individual investigative actions (eg site inspection, search, etc.). Microtraces can be classified according to conditions and time of their formation into the following groups: formation of microtraces that are associated with illegal manufacture, acquisition, storage, sale of explosive weapons or explosives; microtraces of preparation of explosive weapons directly before the explosion; microtraces of explosive weapons. The analysis of the essence of these situations allowed the author to establish and provide an appropriate list of typical microtraces in investigation of terrorist nature crime.

Abstract:
Производство судебных экспертиз по фактам произошедших взрывов и пожаров являются одними из наиболее сложных в работе экспертов. Это связано как с существенным изменением или уничтожением вещной обстановки на местах происшествия, так и с многообразием исследуемых в рамках экспертиз ситуаций и объектов. В случаях, когда на месте происшествия имели место как взрыв, так и пожар, что наиболее часто происходит при взрывах топливно-воздушных смесей и пожарах на складах хранения взрывчатых веществ и боеприпасов, требуется производство соответствующих комплексных экспертиз. В статье рассмотрены вопросы, разрешаемые в рамках комплексной судебной взрыво- и пожарно-технической экспертизы. Приводится подробный анализ экспертных исследований взрыва топливно-воздушной смеси, в том числе взры­ва бытового газа в жилом доме, сопровождающегося пожаром, а также пожара и взрыва на режимном объекте. Forensic examinations of explosive and fire are most difficult expert’s work due to dramatic changes or destructions of scene of accidents and high variability of situation and object that experts have to examine. In cases where explosive and fire happen at once (that most often take place under explosive of fuel-air mixture and fire in the depots of explosive materials and ammunition) complex examinations are necessary. Matters of complex forensic examinations of explosive and fire are considered in article. Detailed analysis of expert examination of explosion and fire of fuel-air mixture in dwelling house and explosive materials in depot of ammunition are considered.

Abstract:
The article deals with the possibilities of digital radiography when conducting diagnostic studies of industrial ammunition and improvised explosive devices during forensic explosive examinations. It is indicated that when conducting diagnostic studies of industrial-made ammunition and improvised explosive devices, there is a possibility of an abnormal operation (explosion) of the ammunition (a high level of danger to the life and health of experts). Therefore, in order to solve diagnostic problems in forensic explosive technical examinations, modern research methods are used, one of which is the non-destructive method. It is indicated that of the available non-destructive methods, the methods of X-ray and gamma-ray transmission have the greatest clarity and objectivity. It can be concluded that the most widespread method for diagnostic studies of industrial ammunition and improvised explosive devices is the method of X-ray transmission from the listed capabilities and characteristics of these methods. The X-ray examination is a non-destructive method of diagnosing research objects using digital radiography. There are listed main tasks of X-ray studies of explosive devices. Further, in the article are presented the possibilities and results of X-ray studies of industrial-made ammunition carried out by experts from the Kyiv Scientific Research Institute of Forensic Expertise of the Ministry of Justice of Ukraine using an X-ray television introscope Go-Scan, manufactured by Teledyne ICM (Belgium). From the results of the analysis of the capabilities of digital radiography during diagnostic studies of industrial-made ammunition and improvised explosive devices, it is concluded that digital radiography makes it possible to determine the internal design of explosive devices without dismantling its, its condition, a possible principle of activation, obtain objective quantitative data, document the obtained in the course of research data, and the addition of additional channels of information makes it possible to significantly expand the amount of information received, to make it more visual, accessible for comparative research, to obtain parametric indicators, which, in turn, improves the quality of diagnostic studies of explosive devices. In addition, a serious advantage of the X-ray method is the ability to conduct research at the location of ammunition and improvised explosive devices or in laboratory conditions without dismantling its, which allows to preserve the research object for its further or re-examination, as well as providing it in the future in the courtroom as physical evidence.

Abstract:
Raman spectroscopy is often considered a nondestructive analytical technique; however, this is not always the case. The 300-mW 785-nm near-infrared (NIR) laser source used with many commercially available instruments has sufficient power to burn samples. This destructive potential is of special concern if the sample is irreplaceable (e.g., fine art, forensic evidence, or for in vivo medical diagnostics) or a hazardous energetic material (explosive or pyrophoric samples). This study quantifies the heat resulting from illuminating an extensive color array with a 785-nm NIR laser and relates these values to the hazards associated with Raman analysis. In general, darker colors were found to be more problematic. Since visible colors are not ideally correlated with absorptive characteristics at 785 nm, predictions based on thermography are not perfect; however, this approximation gives a useful method for predicting the thermal response of unknown samples to NIR exposure. Additionally, experimental studies evaluated the analysis of flammable organic solvents, propellants, military explosives, mixtures containing military explosives, shock-sensitive explosives, and gunpowders (i.e., smokeless, black, and Pyrodex powders). Safety guidelines for analysis are presented.

Detailed spectroscopic measurements of high explosive detonation breakout in the ultraviolet region are presented. Molecular features associated with CN, NH, OH, and N2 are observed and analyzed. Spectra indicate extreme temperatures well in excess of 5000 K in the first few microseconds after breakout. Molecular bands are found to originate from the detonation products, as opposed to the ambient air, and are strongly attenuated in the presence of oxygen. Implications for forensic analysis of source explosive are discussed.

Abstract:
Attention is focused on the interdependence of the relevance of publication with a shortage of scientific and methodological support for forensic research related to the facts of the shelling. The views of international organizations on the use of explosive weapons are presented. It was determined that the use of explosive weapons in populated areas poses a danger of humanitarian problems, which include immediate and long-term consequences for the life and health of civilians, as well as affect civilian infrastructure and the functioning of life support services. Attention is drawn to the dependence of the possibility of access for military personnel who plan to conduct hostilities (operations) in settlements to information on the location and nature of the activities of critical infrastructure facilities and basic life support services of the population on specific conditions. Massive use of high-explosive ordnance in modern armed conflicts is noted. The development trend of this type of ammunition is highlighted. The main damaging factors of the fragmentation and high-explosive ordnance are determined and their characteristics are given. The mechanism of the formation of signs of the direction of an artillery shot to be documented at the scene of the incident is considered. The basic methodological approaches to the study of issues put to resolution in the designated judicial military examinations related to the facts of shelling are shown. The list of basic terms and the most characteristic sources of information about the circumstances of the shelling is given. The main approaches to the procedure for recording the facts of the use of explosive weapons in settlements, as well as in the verification and analysis of relevant data and information regarding the determination of the types of weapons used in shelling, are determined. The list of basic input data required for the study is given. Attention is drawn to the inevitability of the presence of contradictions in the results of documentation, as well as approaches to resolving them are indicated.

Abstract:
Nanotechnology is an important and powerful tool in most the areas including medicine, imaging, andforensic sciences. It is rapidly growing region of research with potential in various fields, running frommedical care to production and physical science. Nanotechnology has a potential to make significantpositive contribution in forensic science in crime detection. Forensic science applies knowledge andmethods from natural science in order to identify, individualize, and assess evidence. Hence, with theaid of evidence, crime scenes can be rebuilt, investigations can be directed, and offenders can be prose-cuted. Nano-analysis use tools like UV Vis spectroscopy, atomic force microscope (AFM), XRD,EDX, Raman micro spectroscopy (Raman), scanning electron microscope (SEM), and transmissionelectron microscope (TEM) (Raman). Moreover, in current article, an attempt was made to elucidatehow nanotechnologies could be crucial in addressing current forensic investigation issues such asexplosive detection, forensic toxicological analysis, finger print analysis, forensic DNA analysis, detec-tion of explosive residue, forensic nano trackers, drug facilitated crime.

Abstract:
Raman chemical imaging (RCI) has been used to detect and identify explosives in contaminated fingerprints. Bright-field imaging is used to identify regions of interest within a fingerprint, which can then be examined to determine their chemical composition using RCI and fluorescence imaging. Results are presented where explosives in contaminated fingerprints are identified and their spatial distributions are obtained. Identification of explosives is obtained using Pearson's cosine cross-correlation technique using the characteristic region (500–1850 cm−1) of the spectrum. This study shows the ability to identify explosives nondestructively so that the fingerprint remains intact for further biometric analysis. Prospects for forensic examination of contaminated fingerprints are discussed.

The paper reflects various aspects of the use of X-ray investigation methods, their advantages and application in forensic science of the phase composition of metals, paint and varnish coatings and paintwork materials, fragments of explosive devices. Practical examples of X-ray diffraction analysis application for thin film specimens made on the basis of paints containing alkyd varnish, pigments, fillers and solvents of various colour range have been examined. Influence of true physical broadening, on lines of diffractograms taken for samples exposed to shock wave action was also studied. It was found that this broadening is directly connected with influence of microstrains and fine dispersion of mosaic structure blocks. Based on the obtained X-ray diffraction analysis data, the dislocation density was calculated by three methods. Based on summarized experimental and literature data, the dependence of microstrains on the explosive weight was plotted, which can be used as a reference standard for comparison in expert studies of samples exposed to shock-wave impact.

Abstract:
During the armed conflict in Colombia, homemade improvised antipersonnel landmines were used to neutralize the adversary. Many active artifacts remain buried, causing damage to biodiversity by exploding. The extensive literature describes the effects and injuries caused to humans by conventional landmines. However, there is considerably less information on the behavior and effects of homemade antipersonnel landmines on fauna and good field investigation practices. Our objectives were to describe the characteristics of a controlled explosion of a homemade antipersonnel landmine (using ammonium nitrate as an explosive substance), to compare the effectiveness of some evidence search patterns used in forensic investigation, and to determine the effects on a piece of an animal carcass. The explosion generated a shock wave and an exothermic reaction, generating physical effects on the ground and surrounding structures near the point of explosion. The amputation of the foot in direct contact with the device during the explosion and multiple fractures were the main effects on the animal carcass. Finally, it was determined that finding evidence was more effective in a smaller search area. Many factors can influence the results, which must be weighed when interpreting the results, as discussed in this manuscript.

Abstract:
The growing threat of terrorism in many parts of the world has called for the urgent need to find rapid and reliable means of analyzing explosives. This is in view to help forensic scientists to identify different swabs from post-blast debris. The present study aims to achieve an efficient separation and identification of a mixture of sixteen explosive compounds (including nitroaromatics, nitramines, and nitrate esters) by high performance liquid chromatography using a diode array detection (HPLC/DAD) and an Agilent Poroshell 120 EC-120 C18 column at two wavelengths (235 and 214 nm). Relevant chromatographic parameters such as capacity factors, resolution, selectivity and number of theoretical plates have been optimized in order to achieve the best separation of the different components. In this respect, the effects of various parameters such as gradient time, column temperature, flow rate of mobile phase and initial percentage organic mobile phase on the separation of these compounds were investigated. It was revealed that the method allowed a fairly acceptable separation of all the compounds in less than 15 minutes except for two isomers, namely 4-A-2,6-DNT, 2-A-4,6-DNT and 2,6- DNT which could not be resolved by the used C18 column. This shortcoming notwithstanding, the developed method produced satisfactory results and demonstrated sensitive and robust separation, furthermore indicating that the HPLC developed method can be both fast and efficient for the analysis of complex mixtures of explosive compounds.

Abstract:
There are many computational techniques to model the consequences to built infrastructure when subject to explosive blast loads; however, the majority of these do not account for the uncertainties associated with system response or blast loading. This paper describes a new computational model, called “Blast-RF” (Blast Risks for Facades), that incorporates existing (deterministic) blast-response models within an environment that considers threat and (or) vulnerability uncertainties and variability using probability and structural reliability theory. The structural reliability analysis uses stress limit states and the UK Glazing Hazard Guide's rating criteria to calculate probabilities of glazing damage and occupant safety hazards conditional on a given blast scenario. This allows the prediction of likelihood and extent of damage and (or) casualties, useful information for risk mitigation considerations, emergency service's contingency and response planning, collateral damage estimation, weaponeering, and post-blast forensic analysis.

Abstract:
Acquiring a clear perspective of events and artefacts that occur over time is a challenging objective to accomplish in digital forensics. Reconstruction of the timeline of events and artefacts, which enables digital investigators to understand the timeline of digital crime and interpret the conclusion in the form of digital evidence, is one of the most paramount and challenging tasks in digital forensics. This challenging task requires the analysis of immense amounts of events because of the explosive growth of the internet, interconnected devices, and innovative technology nowadays. Various approaches have been developed during the last decade, but most of them are not able to handle huge volumes of data, explore evidence, and enhance the understandability of timelines in a competent way to assist the investigator. For this purpose, we introduce a methodology backed by an abstraction concept and forensic tools that can support investigators during the reconstruction, understanding of the timeline of events and artefacts, and interpretation of evidence by tracing the activities performed by users of the typical computer system. The Java programming language is used to implement the proposed methodology, which is object-oriented and follows the symmetry definition in software. Generally, symmetry in software can be viewed as an invariant change that aims to preserve a specific property of the system, namely its structure, behaviour, regularity, similarity, familiarity and uniformity. Similarly, the abstraction-based methodology also permits us to follow the properties of symmetry. For instance, a uniform structure is stipulated for all the sources at the particular level of abstraction, such as the number of fields to be considered to provide the abstract level of timeline. The primary purpose of this approach is to assist with the analysis of the timeline in an optimum way. This paper illustrates the approach and then focuses on conceptual aspects of the methodology. The performed experiment shows that the proposed approach enhanced the analysis of the timeline.

Abstract:
"Romania is currently in an explosive expansion of digitalization created unexpectedly by the COVID-19 pandemic and imposes the need to implement a standardized system in the field of forensic accounting expertise. A digitalized accounting system is essential for streamlining the collaboration between the judiciary and forensic experts. We define digital transformation as the result of fundamental changes in the way literal documentation processes work. This sometimes means moving away from the long-term processes on which the old procedures were built in favour of relatively new practices, which are still undefined. We need a regulatory framework to implement public strategies and policies in the field of digital transformation and the information society. In this sense, a new structure has been organized and operates, the Authority for the Digitization of Romania (ADR), with legal personality within the working apparatus of the Government and under the coordination of the Prime Minister, which includes all departments and services of strategy, coordination, supervision, and implementation in the field of e-government. Analyzing the other branches of the economy we can see areas in which standardized data access systems have been implemented or will be implemented in accordance with the technical requirements of the authorities. An already implemented system can be found in the transfer pricing files where we work in DAC6, an end-to-end cloud solution, which allows collaboration with EU Member States, by reporting xml files. The exhaustive analysis of the situations dealing with the approached subject uses qualitative methods, quantitative methods and the revision of the specialized literature. The aim of the paper is to show how digitization can improve the process of conducting forensic accounting reports, how can justice be more efficient through digitization, what are the challenges of implementing the digitized system in conducting forensic accounting and last but not least what are the aspects of its ethics."

Abstract:
Introduction. Liquefied hydrocarbon gases (LHG) are widely used in various fields. The main components of LHG are: propane, isobutane and n-butane, which are not only combustible, but also explosive gases capable of detonation combustion. The detection of LHG in the air is a very urgent task in expert studies. To determine the component composition of various flammable liquids, for the purpose of their identification, chromatographs equipped with a capillary quartz column with a phase that allows detecting saturated hydrocarbons of the homologous series from pentane to pentatetracontane inclusive are used in the Forensic Expertise Institutions of Federal Fire Service of EMERCOM of Russia. However, it is not possible to analyze the component composition of lighter hydrocarbons according to the previously proposed and used in expert practice method for detecting and studying flammable liquids/high liquids under these conditions. To solve the problem of unification of the use of the instrumental base for the detection of residues of flammable liquids, liquid liquids and light hydrocarbons, new chromatography conditions were selected using the existing equipment set. Goals and objectives. The aim of the study is to select the analysis conditions for detecting the remains of liquefied hydrocarbon gases after explosions of steam-air mixtures on the basis of the instrumental gas chromatographic complex in service with the Forensic Expertise Institutions of Federal Fire Service of EMERCOM of Russia. Research methods. To detect and determine the composition of residues of combustible components during explosions of vapor-gas-air mixtures, a hardware-software instrumental complex based on a gas-liquid chromatograph equipped with a flame ionization detector, a ZB-50 capillary column, and an attachment from a two-stage thermal desorber was used. Results and its discussion. In the course of the study, the optimal conditions for conducting gas chromatographic analysis were defined and selected in order to detect liquefied hydrocarbon gases. Recommended pressures are given for various carrier gases. It is shown that, by varying the pressure and inlet temperature, light hydrocarbons propane, butane, isobutane is fairly well separated on a gas-liquid chromatograph with a flame ionization detector and on a ZB-50 capillary column 30 meters long. Conclusion. The research shows that the problem of combining a hardware-software instrumental complex based on a gas chromatograph with an attachment from a two-stage thermal desorber used for the analysis of two groups of substances (liquefied hydrocarbons and flammable liquids, gas liquids) is solved by varying the pressure and temperature of the input. Keywords: gas-liquid chromatography, thermal desorption, liquefied petroleum gases, light hydrocarbons, air-fuel mixtures, vapor-gas-air mixtures, explosion, fire examination.

Abstract:
Nanotechnology is a powerful tool and fast-growing research area in many novel arenas, ranging from biomedicine to engineering and energy storage. Nanotechnology has great potential to make a significant positive contribution in forensic science, which deals with the identification and investigation of crimes, finding relationships between pieces of evidence and perpetrators. Nano-forensics is related to the development of nanosensors for crime investigations and inspection of terrorist activity by analyzing the presence of illicit drugs, explosives, toxic gases, biological agents, and so forth. In this regard, carbon nanomaterials have huge potential for next-generation nanosensors due to their outstanding properties, including strength combined with flexibility, large specific surface area, high electrical conductivity, and little noise. Moreover, their combination with polymers can provide nanocomposites with novel and enhanced performance owed to synergy between the composite components. This review concisely recapitulates up-to-date advances in the development of polymer composites incorporating carbon-based nanomaterials for forensic science. The properties of the different carbon nanomaterials, several methods used to analyze functional polymeric nanocomposites, and their applications in forensic investigation are discussed. Furthermore, present challenges and forthcoming outlooks on the design of new polymer/carbon nanomaterial composites for crime prevention are highlighted.

Abstract:
Improved protective measures and medical care has increased the survivability from battlefield injuries. In an attempt to reduce the debilitating consequences of blast injury, understanding and mitigating the effects of explosion on the extremities is key. In this study, forensic biomechanical analyses have been applied to determine mechanisms of injury after the traumatic event. The aims of this study were (i) to determine which effects of the explosion are responsible for combat casualty extremity bone injury in two distinct environments, namely open, free-field (open group), and in vehicle or in cover (enclosed group), and (ii) to determine whether patterns of combat casualty bone injury differed between environments. Medical records of casualties admitted to a military hospital in Afghanistan were reviewed over a six-month period. Explosive injuries have been sub-divided traditionally into primary, secondary and tertiary effects. All radiographs were independently reviewed by a military radiologist, a team of military orthopaedic surgeons and a team of academic biomechanists, in order to determine ‘zones of injury’ (ZoIs), and their related mechanisms. Sixty-two combat casualties with 115 ZoIs were identified. Thirty-four casualties in the open group sustained 56 ZoIs; 28 casualties in the enclosed group sustained 59 ZoIs. There was no statistical difference in mean ZoIs per casualty between groups ( p = 0.54). There was a higher proportion of lower limb injuries in the enclosed group compared with the open group ( p < 0.05). Of the casualties in the open group, 1 ZoI was owing to the primary effects of blast, 10 owing to a combination of primary and secondary blast effects, 23 owing to secondary blast effects and 24 owing to tertiary blast effects. In contrast, tertiary blast effects predominated in the enclosed group, accounting for 96 per cent of ZoIs. These data clearly demonstrate two distinct injury groups based upon the casualties' environment. The enclosed environment appears to attenuate the primary and secondary effects of the explosion. However, tertiary blast effects were the predominant mechanism of injury, with severe axial loading to the lower extremity being a characteristic of the fractures seen. The development of future mitigation strategies must focus on reducing all explosion-related injury mechanisms. Integral to this process is an urgent requirement to better understand the behaviour of bone in this unique environment.

Abstract:
Abstract Purpose Explosion-related deaths are uncommon events which require expertise and confidence so that an appropriate death investigation can be performed. The present study aims to provide a detailed forensic analysis of the issues and implications arising in the event of an explosion. Methods A retrospective review of casualty data was conducted on electronic literature databases. Cases concerning deadly explosions registered at the Milan Institute of Legal Medicine were examined and analyzed altogether. Results Explosions may involve closed or open systems. A security assessment of the site is always necessary. Alterations of the site due to rescue procedures can occur; thus, on-site forensic investigation should be adapted to the environment. Then, a study protocol based on autopsy procedures is presented. Application of the postmortem radiology enforces forensic procedures both for the analysis of blast injuries and skeleton fractures, and for identification purposes. Blast injuries typically cause lacerations of the lungs, intestine and major vessels; moreover, hyoid fractures can be documented. Histopathology may help to define blast injuries effectively. Forensic chemistry, toxicology and ballistics provide useful investigative evidence as well as anthropology and genetics. Different forensic topics regarding explosions are discussed through five possible scenarios that forensic pathologists may come across. Scenarios include self-inflicted explosion deaths, domestic explosions, work-related explosions, terrorist events, and explosions caused by accidents involving heavy vehicles. Conclusion The scenarios presented offer a useful instrument to avoid misinterpretations and evaluation errors. Procedural notes and technical aspects are provided to the readers, with an insight on collaboration with other forensic experts.

Abstract:
The thriving terror activity is a menace to our society. To mitigate this, there is a dire need of upgraded and innovative analytical techniques for forensic analysis of explosives. The complexity in the matrix, restrictions in the sample quantity and ambiguity in the data interpretation are the different challenges that a forensic scientist face. The solution to these problems lies in upgradation of extraction technique, screening technique & confirmatory techniques. In this paper, the identification and forensic analysis of post blast residues recovered from controlled blast site has been presented. The targeted sample was extracted from soil by using Accelerated Solvent Extraction technique. The target compound was primarily identified to be PETN (PentaErythritol TetraNitrate) by color test and TLC (Thin Layer Chromatography). The confirmatory test for the target analyte was done by using a hyphenated technique LC-MS/MS (Liquid Chromatography Mass Spectrometer with tandem Mass). This manuscript demonstrates the viability of LC-MS/MS in Forensic Science for a fast, accurate and quality-assured analysis of post-blast residue.

Abstract:
Since the introduction of commercial Fourier transform infrared (FTIR) microscopic systems in 1983, IR microscopy has developed as an important analytical tool in research, industry and forensic analysis. Because of the frequent encounter of small quantities of physical evidence found at crime scenes, spectroscopic IR microscopes have proven particularly valuable for forensic applications. Transmittance and reflectance measurements have proven very useful. Reflection-absorption, specular reflection, and diffuse reflection have all been applied. However, it has been only very recently that an internal reflection (IRS) objective has been commercially introduced.The IRS method, also known as attenuated total reflection (ATR), has proven very useful for IR analysis of standard size samples. The method has been applied to adhesive tapes, plastic explosives, and general applications in the analysis of opaque materials found as evidence. The small quantities or uncontaminated areas of specimens frequently found requiring forensic analysis will often be directly applicable to microscopic IRS analysis.

Abstract:
A mass disaster is a situation that involves criticality between the number of victims and resources, in terms of both men and means, present on the site of an event that is mostly unexpected and sudden. In the multidisciplinary teams that intervene, the role of forensic pathologists, who are responsible for the direction and coordination of post-mortem operations, is central, and must remain so. The authors report the case of an explosion of a pyrotechnic artifice factory, as a result of which numerous victims and injuries are recorded. So, the team completed the autopsies and created a protocol to obtain biological samples (bones, blood, teeth, muscles), while the forensic pathologists contacted the families of the alleged victims and each provided a blood sample that was collected for the DNA. The geneticist, using the method of gene extraction and amplification, obtained the DNA from each bone, tooth, and muscle of blood taken from the victims and then compared it with that extracted from the blood samples of the relatives; the electropherograms showed at least one allele for each genetic marker of the “Combined DNA Index System” in common between the victims and the families, thus allowing to establish the identity of all the subjects involved in the event. Having established the identity of all workers, it was possible to determine their whereabouts in the environment at the time of the location of fires and explosions. The results of the various forensic analyzes (autopsies, genetic investigations and even traumatological investigations) have allowed us to validate a scientific method useful in all mass disasters even when any type of anthropological or forensic dental research is difficult.
