Interaction between carbon monoxide and ethanol in fire fatalities. Impairment due to ethanol is clearly a risk factor in deaths due to fire. However, it is forensic science research paper clear whether there is a physiological interaction between ethanol and carbon monoxide CO that would alter the carboxyhemoglobin saturation However, it is less clear whether there is a physiological interaction between ethanol and carbon monoxide CO that would alter the carboxyhemoglobin saturation level COHb sat.
that accounts for death. In an attempt to explore this issue further, fire fatalities investigated by the Office of. Archaeological, radiological, and biological evidence offer insight into Inca child sacrifice, forensic science research paper. Examination of three frozen bodies, a y-old girl and a girl and boy aged 4 to 5 y, separately entombed near the Andean summit of Volcán Llullaillaco, Argentina, sheds new light on human sacrifice as a central part of the Imperial Inca Examination of three frozen bodies, forensic science research paper, a y-old girl and a girl and boy aged 4 to 5 y, separately entombed near the Andean summit of Volcán Llullaillaco, forensic science research paper, Argentina, sheds new light on human sacrifice as a central part of the Imperial Inca capacocha rite, described by chroniclers writing after the Spanish conquest.
The high-resolution diachronic data presented here, obtained directly from scalp hair, implies escalating coca and alcohol ingestion in the lead-up to death.
These data, combined with archaeological and radiological evidence, deepen our understanding of the circumstances and context of final placement on the mountain top. We argue that the individuals were treated differently according to their age, status, and ritual role. Attachment Models in Incarcerated Sex Offenders: A Preliminary Italian Study Using the Adult Attachment Interview. Results showed significant differences between offenders and control adults on both the AAI continuous score and the distribution of the two-way attachment classifications.
Furthermore, sex offenders reported more intense experiences of rejection by the father figure and abuse in the family context during early childhood compared to not offenders subjects with the same attachment classification, forensic science research paper.
Investigation of the use of luminescent markers as gunshot residue indicators. The addition of luminescent markers into ammunition cartridges is an appealing proposal to achieve a greater individual identification of the ammunition. The lanthanide elements present in these luminescent materials act as characteristic The lanthanide elements present in these luminescent materials act as characteristic chemical markers that, also, offer the great benefit of making gunshot residues GSR collection easier.
Although the use of luminescent markers offers numerous advantages, and can be a reliable future option in the cartridge ammunition market, little or nothing is known about the interaction of the marker with the ammunition compounds after the shot. For the forensic laboratories, it is of utmost importance to anticipate the commercialization of tagged luminescent ammunition by knowing the type of particles produced after the discharge. That is, to investigate if markers merge with GSR to form single particles or, on the contrary, they form individual particles that travel separately from the GSR particles.
In this work, conventional ammunition ca Study of losses of volatile compounds from dynamites. Investigation of cross-contamination between dynamites stored in polyethylene bags. The purpose of this work was to study the appropriateness of polyethylene bags for the preservation of explosive specimens. To this end, specimens of two types of dynamites, Goma-2 EC, containing nitroglycol EGDN and dinitrotoluene To this end, specimens of two types of dynamites, Goma-2 EC, containing nitroglycol EGDN and dinitrotoluene DNTand Goma-2 ECO, containing only EGDN, were placed individually inside bags and introduced into hermetically sealed glass jars, which were stored for a period of time.
Losses of volatile compounds were studied by headspace analysis using gas chromatography coupled to mass spectrometry GC-MS. The cross-contamination between dynamites was studied by using high performance liquid chromatography with mass spectrometry HPLC-MS to analyse the extracts obtained after a sequential solvent extraction of these specimens. Polyethylene bags permit the loss of volatile compounds since EGDN and DNT were detected in the headspaces of the jars.
Moreover, cross-contamination between dynamites was also demonstrated since DNT content decreased in the dynamite containing this compound and increased in the dynamite that had not contained it. Forensic discrimination of blue ballpoint pens on documents by laser ablation inductively coupled plasma mass spectrometry and multivariate analysis.
The differentiation of blue ballpoint pen inks written on documents through an LA-ICP-MS methodology is proposed. Small common office paper portions containing ink strokes from 21 blue pens of known origin were cut and measured without Small common forensic science research paper paper portions containing ink strokes from 21 blue pens of known origin were cut and measured without any sample preparation. In a first step, Mg, Ca and Sr were proposed as internal standards ISs and used in order to normalize elemental intensities and subtract background signals from the paper.
This treatment improved the discrimination power DP and provided objective results, achieving a complete differentiation among different brands and a partial differentiation within pen inks from the same brands. The designed data treatment, together with the use of multivariate statistical tools, represents an easy and useful tool for differentiating among blue ballpoint pen inks, with hardly sample destruction and without the need for methodological calibrations, being its use potentially advantageous from a forensic-practice standpoint.
To test the procedure, it was applied to analyze real handwritten questioned contracts, previously studied by the Department of Forensic Document Exams of the Criminalistics Service of Civil Guard Spain. The results showed that all questioned ink entries were clustered in the same group, being those different from the remaining ink on forensic science research paper document. To this end, specimens of two types of dynamites, Goma-2 EC, containing nitroglycol EGDN and dinitrotoluene DNTand Goma-2 ECO, containing only EGDN, Urinary Excretion of Commonly Abused Drugs Following Uncommon Means of Administration.
Although abused drugs are administered most often by preferred routes, unconventional routes also may be employed. Urine testing is often used to document recent drug exposure, forensic science research paper.
Much of the scientific literature on urine testing concerns studies of conventional routes of drug administration. This article reviews current data on urine testing following unconventional means of administration of drugs of abuse. In each section, a brief review of the principles involved in each unusual route is followed by a discussion of studies and case reports in which urine was tested for drugs of abuse. Special mention is made of the danger of passive inhalation to small children and in utero exposure to fetuses.
It is hoped that this review will sensitize those involved in interpretation of urine test data to the many possible wa Validity testing of the TDX® cocaine metabolite assay with human specimens obtained after intravenous cocaine administration.
Urinary excretion profiles of norcarboxy-Δ9-tetrahydrocannabinol and hydroxy-Δ9-THC: cannabinoid metabolites to creatinine ratio study IV. Legal, workplace, and treatment drug testing with alternate biological forensic science research paper on a global scale.
Global trends in drug trafficking and drug usage patterns indicate a continuing pattern of escalation throughout the world. Over the last two decades, urinalysis has evolved into a highly accurate means for determining whether individuals Over the last two decades, urinalysis has evolved into a highly accurate means for determining whether individuals have been exposed to illicit drugs of abuse. Advances have also been made in the use of alternate biological matrices such as hair, oral fluids and sweat for drug testing.
Often, these new matrices demonstrate some distinct advantages over urinalysis, e. less invasive procedures, different time course of drug detection. They may even indicate impairment. National and local laws of each country provide the underpinnings of drug-testing programs, but most countries have not addressed use of these alternate matrices.
Currently, only a few countries have statutes that specifically mention use of alternate biological matrices, e. United States Florida state lawGermany, Forensic science research paper, Poland and the Czech Republic. Conversely, forensic science research paper, few countries have prohibited collection of alternate biological specimens or drug test devices that utilize such specimens.
In addition, guidelines for implementing drug testing programs have been slow to emerge and most deal primarily with workplace drug testing programs, e. United States. Currently, scientific technology utilized in drug testing is advancing rapidly, but there is a clear need for parallel development of guidelines governing the use of alternate matrices for drug testing. This article provides an overview of global drug trafficking patterns and drug use, and results from a survey of legal statutes in 20 countries covering use of alternate matrices for drug testing.
In addition, elements needed for the development of guidelines for alternate matrices testing for drugs of abuse are discussed, and specific examples of use of alternate matrices in treatment monitoring are provided. Urine testing for norcodeine, norhydrocodone, and noroxycodone facilitates interpretation and reduces false negatives.
Oral fluid results compared to self reports of recent cocaine and heroin forensic science research paper by methadone maintenance patients. Although self reports of illicit drug use forensic science research paper not be reliable, this information is frequently collected and relied upon by national drug surveys and by counselors in drug treatment programs. The addition of oral fluid testing to these The addition of oral fluid testing to these programs would provide objective information on recent drug use.
The goal of this study was to compare oral fluid tests for cocaine, benzoylecgonine, 6-acetylmorphine, morphine, codeine and 6-acetylcodeine to self reports of recent cocaine and heroin use by patients in an outpatient methadone treatment program, forensic science research paper.
