Journal articles on the topic 'Post mortem photography'

This article explores the custom of post-mortem photography. In nineteenth century America, this was a socially acceptable, publicly acknowledged form of photography. Professional photographers accepted commissions, advertised the service, and held professional discussions in their journals about the practice. The images were publicly displayed in wall frames and albums. Initially, death pictures were portraits which attempted to deny death by displaying the body as if asleep, or even conscious. By the turn-of-the-century, the deceased were displayed in a casket with an increasing emphasis upon the funeral. Today, families make their own photos; circulating them in a private manner so that many people assume that the custom has been abandoned. Counselors working with the parents of children who have died provide evidence that these images can be useful in the mourning process. The findings of this study suggest that a more thorough examination of the place of death-related photographs in the management of grief would be of value.

Pathologists providing a coronial autopsy service are very reliant on the information, including that concerning the body at the scene, provided prior to the post-mortem examination. This ensures the case is appropriate for a non-forensic autopsy and allows proper interpretation of the pathological and laboratory findings. We present the results of an audit of the extent and accuracy of the information provided (in terms of a set of descriptors), in relation to the body at the scene; whether just the information on the coronial autopsy request form 97a is used, or if it is supplemented with details from the police form 97 and statements from attending officers and scene witnesses. The scene photographs were then reviewed to assess the accuracy of the other information sources and their value to the reporting pathologist. The audit showed that scene photographs are undertaken surprisingly frequently (29.6%) but this was only clear from the coronial request in 22% of referrals. More information was consistently available in the police information for most of the scene descriptors. This was usually accurate, but only partially so, with an average of 19% of relevant features. Viewing the scene photographs was deemed beneficial or essential in 51% and 41.1% of cases. The value of scene photography is then illustrated in a case of suspected suicidal venous air embolism, where subsequent review of the images pointed strongly to the rapidity of death, with minimal blood loss but obvious targeting of a very large varicose saphenous vein in the upper thigh.

The Taylor test is used to determine damage evolution in carbon-fibre composites across a range of strain rates. The hierarchy of damage across the scales is key in determining the suite of operating mechanisms and high-speed diagnostics are used to determine states during dynamic loading. Experiments record the test response as a function of the orientation of the cylinder cut from the engineered multi-ply composite with high-speed photography and post-mortem target examination. The ensuing damage occurs during the shock compression phase but three other tensile loading modes operate during the test and these are explored. Experiment has shown that ply orientations respond to two components of release; longitudinal and radial as well as the hoop stresses generated in inelastic flow at the impact surface. The test is a discriminant not only of damage thresholds but of local failure modes and their kinetics. This article is part of the themed issue ‘Multiscale modelling of the structural integrity of composite materials’.

AbstractThe use of sclerobiosis as a tool for paleoenvironmental and paleoecological research is undermined by a lack of comparable methods for sclerobiont data collection and analysis. We present a new method for mapping sclerobiont distributions across any host, and offer an example of how the method may be used to interpret sclerobiont data in relation to host orientation. This approach can also be used to assess the suitability of beds and fossil material for paleoenvironmental reconstruction.A sample of 150 encrusted dorsibiconvex atrypide brachiopods were selected from six beds in the Waterways Formation (latest Givetian – Early Frasnian; Alberta, Canada). The dorsal and ventral valves of each brachiopod were photographed. Sclerobiont taxa were mapped onto the photographs, and the maps were used to create stacked images with each of the 25 brachiopod specimens from each bed. Based on the life orientation of dorsibiconvex atrypides, three zones were designated on the host: the post mortem zone, (only available to sclerobionts after death and reorientation of the host); the shaded zone (brachial valve, excluding the post mortem zone); and the exposed zone (ventral valve).Randomization simulation results indicate that all beds likely exhibit non random encrustation patterns, and corroborate the hypotheses that: (1) much of the encrustation occurred while the hosts were alive, and (2) these beds and fossils have experienced little physical reworking or transport and would be suitable for paleoenvironmental analysis. Mapping sclerobionts across hosts can serve as a unifying method to increase the recognition and use of sclerobiosis in paleontological studies.

Abstract Microenvironments play a significant part in understanding the post-mortem interval in forensic taphonomy. Recently, the value of weathering factors in relation to obtaining a PMI has been investigated further. In this study, observations were made to calculate the length of time it takes for three different bone elements (femur, rib, and scapula) to bleach in a UK summer and winter. This research also investigated whether there were any physicochemical modifications to the bone caused by bleaching. Porcine femora, scapulae, and ribs were placed into open and shaded areas of an outdoor research facility located in Oxfordshire, UK, during summer (July–Sep) and winter months (Dec–Mar). The specimens were monitored at 3-week intervals using photography, and an observational scoring method was developed to quantify the extent of bleaching. As temperatures are typically much lower in the UK compared with warmer climates, a controlled indoor-simulated desert experiment was also undertaken to be used as a control. This allowed sun bleaching and changes to the bone chemistry to be monitored in a controlled, high-UV environment for comparison with the UK outdoor experiments. Fourier transform infrared spectroscopy (FTIR) was employed to analyze physicochemical modifications to both the mineral and organic components of the bone. The FTIR was used to calculate crystallinity index (CI), mineral to organic ratio, and the relative amount of carbonate concentrations. Weather data was collected and a positive correlation was found between both ultraviolet (UV) levels and accumulated degree days (ADD) when compared with observational bleaching scores. Bleaching (whitening) of the bone samples occurred in both seasons but at different rates, with the bleaching process occurring at a slower rate in winter. During summer, the initial bleaching process was evident at 6 weeks, and by 9 weeks, the bones were an off-white colour. During the winter period, whitening of the bone started at 9 weeks; however, only the scapula and rib samples displayed a similar off-white colour. This colouration was observed at 13 weeks rather than at 9 weeks. The desert simulation samples started bleaching in a similar pattern to the outdoor samples after 1 week but the bones did not fully bleach. The bone chemistry, based on physicochemical properties obtained from the FTIR, showed a significant statistical difference between the simulated desert and winter season when compared against a control sample. For the winter samples, the mineral to organic ratio was significantly higher than that in the control, suggesting a reduction in the proportion of organic. For the samples in the simulated desert environment, the crystallinity index was significantly higher than that in the control samples, suggesting an increase in crystallinity. The results of this experiment support the fact that it is possible to achieve bleaching in a UK environment and that the minimal time frame for this to occur differs in seasons.

SummaryIn the framework of the biodiversity initiative and barcoding project “Austrian Barcode of Life” (ABOL) post mortem examinations of the gastro-intestinal tracts of different species of wild birds were carried out and several adult helminths were retrieved. In the gizzard of two barn owls (Tyto alba) and one common kestrel (Falco tinnuculus) acuariid nematodes belonging to the species Synhimantus (Synhimantus) laticeps (Rudolphi, 1819) were discovered. This report illustrates the identification of this parasitic nematode by morphometric comparison and scanning electron microscopic photographs. Furthermore, genetic identification of individual parasites based on a fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear 18S ribosomal RNA gene was carried out. This report constitutes the first COI-based DNA barcoding of S. (S.) laticeps and its first record in the barn owl (Tyto alba) in Austria.

ABSTRACT: Histological sections of post-mortem tissues are often poorly preserved and many pathologists feel that washing tissues during the autopsy may contribute to this. This proposition was tested by immersing blocks of fresh tissue in tap water for 10 minutes and assessing the histological preservation of subsequent tissue sections. Blocks of liver were also kept in tap water for periods of up to 34 hours and the amount of tissue damage was assessed using routine histology. All slides were coded and interpreted by an observer who had not previously seen the tissues. Photographs of the various tissues stained with a variety of techniques were also offered to a group of pathologists, at a Pathological Society meeting, who also attempted to classify them as ‘washed’ or ‘unwashed’. The results were statistically random and showed that washing tissues in the manner described had no deleterious effect on subsequent histological preparations. We conclude that there is no reason to avoid washing tissues during the routine autopsy.

Documentation regarding the practical mathematicians in the early modern age is as rare as it is precious. In fact, where it exists, it permits us to document the culture of mathematics at a time of strong interchanges between the ‘artisan epistemology’ and erudite scientific culture. This paper will present a complete edition of the post-mortem inventory of the Roman mathematician Gaspare Berti (1601–1643), which was discovered among the notary papers of the Roman Court of Auditor Camerae. This document is of great interest, both generally and in particular. On the one hand, it sheds light on a figure who has remained unknown for centuries, except for his pioneering work on the vacuum in the early 17th century. On the other hand, thanks to an exceptional wealth of details, through the inventory we are given a deeper look from within at the ‘trading zone’ between practical and theoretical mathematics in the particular context of Baroque Rome. This almost photographic documentation contextualizes the lively world of practical mathematics, allowing comparison with the ‘big narrative’ of its alleged decline after Galileo’s condemnation.

Horses and donkeys belong to the genus Equus, but important differences exist between the species, many of which affect their management and welfare. This study compared skull morphology between horses and donkeys. Horse (n = 14) and donkey (n = 16) heads were obtained post-mortem, sectioned sagittally close to the midline, and photographed for subsequent measurement of various skull structures. Skull, cranial, nasal, and profile indices were calculated for topographical comparisons between the species. The olfactory bulb area (OBA), OB pitch (the angle between the hard palate and the OB axis), and whorl location (WL) were also measured. A General Linear Model determined the main effect of species with Sidak’s multiple comparisons of species’ differences among the various measurements. There was no species difference in cranial or nasal indices (p > 0.13), but donkeys had a larger cranial profile than horses (p < 0.04). Donkeys had a smaller OBA (p < 0.05) and a steeper OB pitch (p < 0.02) than horses. The WL corresponded to the level of the OB in horses but was extremely rostral in donkeys (p < 0.0001). These results show clear differentiation in skull morphology between horses and donkeys. This may be useful in validating other physiological and behavioural differences between horses and donkeys.

Whaling has decimated North Atlantic right whales Eubalaena glacialis (NARW) since the 11th century and southern right whales E. australis (SRW) since the 19th century. Today, NARWs are Critically Endangered and decreasing, whereas SRWs are recovering. We review NARW health assessment literature, NARW Consortium databases, and efforts and limitations to monitor individual and species health, survival, and fecundity. Photographs are used to track individual movement and external signs of health such as evidence of vessel and entanglement trauma. Post-mortem examinations establish cause of death and determine organ pathology. Photogrammetry is used to assess growth rates and body condition. Samples of blow, skin, blubber, baleen and feces quantify hormones that provide information on stress, reproduction, and nutrition, identify microbiome changes, and assess evidence of infection. We also discuss models of the population consequences of multiple stressors, including the connection between human activities (e.g. entanglement) and health. Lethal and sublethal vessel and entanglement trauma have been identified as major threats to the species. There is a clear and immediate need for expanding trauma reduction measures. Beyond these major concerns, further study is needed to evaluate the impact of other stressors, such as pathogens, microbiome changes, and algal and industrial toxins, on NARW reproductive success and health. Current and new health assessment tools should be developed and used to monitor the effectiveness of management measures and will help determine whether they are sufficient for a substantive species recovery.

At the 2017 SPNHC meetings in Denver, a five-minute Storage Techniques for Art, Science and History (STASH) talk was presented on the cold storage of film-based media. Herein, a more in-depth presentation of the Smithsonian's archival project with a status update is provided. In February 2016 world-renowned ichthyologist John E. Randall (Jack) donated his 10,559 film-based slide collection of fishes to the Smithsonian Institution National Museum of Natural History (NMNH). Beginning in the 1970’s, Jack used predominately 120mm Ektachrome film to photograph marine fishes. The first-generation slides were stored in cool storage, approximately 40F/4.5C, for much of their lives, thus preserving film color quite well as well as extending the life expectancy of film. Although digital surrogates of the slides have been created, the Division of Fishes intends to ensure the stabilization of the original color film by placing the slides in cold (-4F/-20C) storage. Color dyes used in Ektachrome slide film are fairly fugitive, and a known strategy to slow the rate of fading is to store slides in the coldest storage possible. NMNH Division of Fishes rehoused slides based on methods developed by the US National Park Service and the US National Gallery of Art. Prior to placing into cold storage, the slides were rehoused using archival supplies. The packaging methods we used are to prevent or reduce inherent deterioration as well as to help prevent any condensation buildup during the acclimation period that can occur when moving between quite differing temperature environments. In this discussion, I will evaluate the processes and materials used as well as to reflect on post-mortem takeaways.

Over the last decade, with the advent of aberration correctors and energy-filters, transmission electron microscopes (TEMs) have seen phenomenal developments both in regards to spatial and spectral resolutions. Today, the TEM is a characterisation tool pervasive to nanoscaled sciences and technologies. Imaging and identifying single atoms, including low Z elements such as B or C, is within reach of a skilful operator with access to this new generation of microscopes.Parallel to these advances, sample holders have also been evolving. Instead of just fixing and orienting the sample for observation, these ancillary components of TEMs have gradually been morphing into full-fledged instruments. Increasingly sophisticated devices enable a multitude of experiments performed inside the column of the TEM which includes the manipulation and exposure of discrete nanostructures to a variety of stimuli (heat, pressure, electrical current…). An example is the real-time observation of solid-vapour phase transitions in filled carbon nanotubes acting as interconnects and experiencing the dynamical effects of Joule heating. Together with resolution improvements, these added capabilities represent a paradigmatic shift in how we perceive and work with TEMs. No longer is the electron microscopist limited to simply analyse specimens in “post-mortem” state but (s)he can now take hold of a full set of physical and chemical experiments that encompass a much broader range of scientific interests.Despite all progress, there is a crucial part of the TEM capabilities that is still awaiting a similar leap in resolution: the time-domain. In result of the past dominance of “post-mortem” analysis, a temporal resolution enhancement has been overlooked by most instrument manufacturers and researchers. However, with the growing interest on in situ methodologies, the ability to perform time-resolved experiments has suddenly become a fundamental necessity. Classically, registering tools such as photographic films, charge-coupled devices or video-rated cameras have been adequate to acquire data on events that take place on timescales ranging from seconds to hours. Such temporal resolution is not sufficient for an immensity of life- and materials science-related processes. To illustrate this, Figure 1 shows the before and after states of a ZnS-filled carbon nanotube that was subjected to a pulse of electrical current. Although it is possible to observe clearly the end result, one can only speculate on how the confined semiconductor was released, transported and delivered to the receiving substrate. Considering that the pulse lasted for 250 ms, a temporal resolution of at least 50 ms (or 20 frames per second) for the registering device would be necessary to build a reasonable impression of the mechanism behind this delivery-procedure.PMFJC acknowledges the support from the Fundação para a Ciência e Tecnologia (Ciencia2007 Fellowship and project grant PTDC/EME-PME/112073/2009) and Alexander von Humboldt Foundation (Advanced Researcher Fellowship).

Background: The sternum is one of the skeleton parts with frequently detected variation in cross-sectional images or autopsy series. The anatomical or congenital variations of the sternum in the anterior chest wall may involve malignancies, injuries or severe traumas. The aim of the study was undertaken to evaluate the incidence of anatomical and congenital variations of human dry sternum bones.Methods: This study was carried out on 120 dry human sternum bones irrespective of age and sex at Varun Arjun medical college- Banthra, UP, KMCT Medical College, Manassery-Calicut and Melaka Manipal Medical College-Manipal. All the sternum bones were macroscopically inspected for the anatomical and congenital variations of human dry sternum bones. Photographs of the anatomical and congenital variations were taken for proper documentation.Results: Complete sternal foramina in the body of the sternum were noted in 9 bones (7.5%), with an average vertical diameter of 17mm and transverse diameter of 16mm (The highest vertical diameter of 19mm and transverse diameter of 17mm was noted); Incomplete sternal foramina in the body of the sternum were noted in 4 bones (3.3%);Complete sternal foramina in the xiphoid process of the sternum were noted in 7 bones (5.8%) with an average vertical diameter of 6mm and transverse diameter of 8mm; Unusual complete sternal foramina in the body and incomplete sternal foramina in the xiphoid process of the sternum were noted in 8 bones (6.6%); Very rare longer xiphoid process (7.3 cm) with complete sternal foramina was noted in 7 bone (5.8%); Unusual Longer xiphoid process with an average length of 6.7cm with sharp bifid ends was noted in 8 bones (6.6%).Conclusions: The knowledge of existence of anatomical variants and congenital foramina of sternum and xiphoid process found in our study is essential, especially for bone marrow sampling, radiology (X - ray, CT, MRI, and USG) reporting, pathology autopsy and forensic medicine post-mortem reporting and patoacupuncture practice to avoid complications during various surgical procedures.

BACKGROUND The papillary muscle basal connections have significant clinical implications. Variety of studies done on its morphology and function by various specialists in different departments. A close look on these revealed the interconnections of papillary muscles to one another and to the interventricular septum of both ventricles is related to uncoordinated contractions of papillary muscles, leading to hyper or hypokinesia or prolapse or even its rupture. METHODS Our study done in 25 formalin soaked hearts revealed after the deep and meticulous dissection, reflecting the walls of ventricles laterally the numerous interconnections of papillary muscles at its bases and IVS. Ventricles are opened by inverted ‘L’ shaped incision and its reflected more laterally till all the papillary muscles is visible in one frame after incising the moderator band. The connections were noted, measured, photographed, tabulated, compared with similar studies and analysed with experts with respective fields. RESULTS Almost all the specimens did have the interconnections. Further the post mortem findings of the cardiac related deaths with involvement of papillary muscles suggest damage to such ‘bridges’. The moderator band extensions to the base of right APM, and its extension to the posterior groups is noted in all the specimens. The bridge from the IVS to bases of both the groups of papillary muscles is noted in left ventricle. In90% of specimens the one PPM is found to be loosely connected, more so in left ventricle. CONCLUSIONS We are of a conclusion that such basal interconnections and to the interventricular septum are responsible for rhythmic contractions of papillary muscles of both ventricles. Since the AV valves have to open simultaneously, interconnections becomes mandatory as the impulse has to reach it before it reaches the trabeculae carniae. One of the Posterior papillary muscles is loosely connected to other papillary muscles, may be the reason for its rupture, more so in left ventricle.

The only direct source of information about hominin brain evolution comes from the fossil record of endocranial casts (endocasts) that reproduce details of the external morphology of the brain imprinted on the walls of the braincase during life. Surface traces of sulci that separate the brain’s convolutions (gyri) are reproduced sporadically on early hominin endocasts. Paleoneurologists rely heavily on published descriptions of sulci on brains of great apes, especially chimpanzees (humans’ phylogenetically closest living relatives), to guide their identifications of sulci on ape-sized hominin endocasts. However, the few comprehensive descriptions of cortical sulci published for chimpanzees usually relied on post mortem brains, (now) antiquated terminology for some sulci, and photographs or line drawings from limited perspectives (typically right or left lateral views). The shortage of adequate descriptions of chimpanzee sulcal patterns partly explains why the identities of certain sulci on australopithecine endocasts (e.g., the inferior frontal and middle frontal sulci) have been controversial. Here, we provide images of lateral and dorsal surfaces of 16 hemispheres from 4 male and 4 female adult chimpanzee brains that were obtained using in vivo magnetic resonance imaging. Sulci on the exposed surfaces of the frontal, parietal, temporal, and occipital lobes are identified on the images based on their locations, positions relative to each other, and homologies known from comparative studies of cytoarchitecture in primates. These images and sulcal identifications exceed the quantity and quality of previously published illustrations of chimpanzee brains with comprehensively labeled sulci and, thus, provide a larger number of examples for identifying sulci on hominin endocasts than hitherto available. Our findings, even in a small sample like the present one, overturn published claims that australopithecine endocasts reproduce derived configurations of certain sulci in their frontal lobes that never appear on chimpanzee brains. The sulcal patterns in these new images also suggest that changes in two gyri that bridge between the parietal and occipital lobes may have contributed to cortical reorganization in early hominins. It is our hope that these labeled in vivo chimpanzee brains will assist future researchers in identifying sulci on hominin endocasts, which is a necessary first step in the quest to learn how and when the external morphology of the human cerebral cortex evolved from apelike precursors.

One of the great paradoxes of the modern world is that India, the land that produced such major world religions as Buddhism Jainism is now torn apart by caste and communal violence. Pakistan and Sri Lanka, like India, face severe ethnic problems. Law and order are to be emphasized. Caste and community must be protected by the executive branch of the Indian Government. This bas been laid down in the rules framed by the legislative branch. When this is not done there is a breakdown. No one is safe and no group is secure. In India today this is clearly the case. This book by M. J. Akbar is a collection of 15 journalistic pieces, written for Akbar's newspaper and magazine, The Telegraph and Sunday over the last decade. Because it is journalism, the important "burning" issues are covered such as the Moradabad massacre in 1980, the slaughter of the Uttar Pradesh Harijans in 1981 and the ongoing Babri Masjid controversey. It is journalism, but the writing is of high quality and evocative: "It is early morning and a mist lies on the river, making the pre-dawn haze more blurred. A part of the Howrah Bridge looms through the gauze, like a picture deliberately created by a photographer in search of art. The fires are out." (p. 170) Akbar's material is hard, brittle, compelling stuff. He writes with the passion of the committed and his commitments are to secularism, to humanity, to the truth, as he sees it, on the ground. Here, a brief account of Dr. Akbar's cultural background seems appropriate: He was born in 1951 and has become the English-speaking voice of post-Midnight's Children of India. The significance of post 1947 independence as a dividing line is generally not fully appreciated. Missing is the literary, sentimental romanticism of the earlier Indian generation of writers. Don Moraes and Ved Mehta already appear as dated figures of the past. Their India is another country. In Akbar's background there is no punting on English rivers, laboring at Oxford intonations, getting drunk after the Oxford-Cambridge boat race nor leisurely reading of the English romantic poets on the banks of the Cam. Akbar lives in the urban nightmare of Calcutta and in his nostrils is the smell of burning flesh and rotting corpses. Missing, though he is aware of the loss, is the romantic vision of Nehru and the religious idealism of Gandhi. Akbar is an Indian writing with a white-hot pen for Indians of today's India ...

AbstractThe photoreceptor-specific nuclear receptor Nr2e3 is not expressed in Nr2e3rd7/rd7 mice, a mouse model of the recessively inherited retinal degeneration enhanced S-cone sensitivity syndrome (ESCS). We characterized in detail C57BL/6J Nr2e3rd7/rd7 mice in vivo by fundus photography, optical coherence tomography and fluorescein angiography and, post mortem, by histology and immunohistochemistry. White retinal spots and so-called ‘rosettes’ first appear at postnatal day (P) 12 in the dorsal retina and reach maximal expansion at P21. The highest density in ‘rosettes’ is observed within a region located between 100 and 350 µM from the optic nerve head. ‘Rosettes’ disappear between 9 to 12 months. Non-apoptotic cell death markers are detected during the slow photoreceptor degeneration, at a rate of an approximately 3% reduction of outer nuclear layer thickness per month, as observed from 7 to 31 months of age. In vivo analysis of Nr2e3rd7/rd7 Cx3cr1gfp/+ retinas identified microglial cells within ‘rosettes’ from P21 on. Subretinal macrophages were observed in vivo and by confocal microscopy earliest in 12-months-old Nr2e3rd7/rd7 retinas. At P21, S-opsin expression and the number of S-opsin expressing dorsal cones was increased. The dorso-ventral M-cone gradient was present in Nr2e3rd7/rd7 retinas, but M-opsin expression and M-opsin expressing cones were decreased. Retinal vasculature was normal.

Taphonomic studies through experimental research at Forensic Anthropological Research Facilities are continuously developing our understanding of soft tissue decomposition in controlled environments. Photographic archives provide an alternative means to study decomposition using associated detailed case notes, environmental variables surrounding the death and (if known) post-mortem interval (PMI). Leccia, Alunni and Quatrehomme (2018) utilized this resource to calculate the total body surface area (TBSA) in bodies with extensive and complete mummification using “the rule of nines,” a method where the body is sectioned into nine anatomical sections to assess TBSA burnt however they did not test this statistically. This article aims to revise their study by implementing the more representative Lund and Browder chart (Yasti et al. 2015) to visually assess all degree of mummification and skeletonization, through a secondary data analysis study using autopsy photographs of 17 cases from Allegheny County Medical Examiner’s Office, Pittsburgh, between 2007–2016. Principal component analysis (PCA) was conducted on the body section scores to reveal high correlation co-efficients (>0.95) between anatomical sections indicating a high confidence, mummification and/or skeletonization on multiple body parts will co-exist on a decomposed body. PCA of recorded variables revealed that after body position was removed from analysis, the majority of variables had strong values. i.e., those with a numerically large magnitude (.750 to .850, -.767 to -.840). Multiple regression analysis and ANOVA revealed age to be the significant independent variable at 10% significance level. The results of this study have forensic application for crime scene investigators, mummification and skeletonization percentages can be effectively recorded upon examination of a body, whilst also demonstrating variables that have a significant effect on presentation of these two post-mortem changes. Further examination of globally dependant variables affecting modern mummification is encouraged.

Photograph by Gonzalo Echeverria (2010)Doubt has been my closest companion for several years as I struggle to make sense of certain hidden events from within my family’s history. The actual nature of such events, although now lost to us, can nevertheless be explored through the distorting lens of memory and academic research. I base such explorations in part on my intuition and sensitivity to emotional experience, which are inevitably riddled with doubt. I write from the position of a psychoanalytic psychologist who is also a creative writer and my doubts increase further when I use the autobiographical impulse as a driving force. I am not alone with such uncertainties. Ross Gibson, an historian and filmmaker, uses his doubts to explore empty spaces in the Australian landscape. He looks to see “what’s gone missing” as he endeavours with a team of colleagues to build up some “systematic comprehension in response to fragments” (Gibson, “Places” 1). How can anyone be certain as to what has transpired with no “facts” to go on? he asks. What can we do with our doubts? To this end, Gibson has collected a series of crime scene photographs, taken in post war Sydney, and created a display – a photographic slide show with a minimalist musical score, mostly of drumming and percussion, coupled with a few tight, poetic words, in the form of haiku, splattered across the screen. The notes accompanying the photographic negatives were lost. The only details “known” include the place, the date and the image. Of some two thousand photos, Gibson selected only fifty for display, by hunch, by nuance, or by whatever it was that stirred in him when he first glimpsed them. He describes each photo as “the imprint of a scream”, a gut reaction riddled with doubt (Gibson and Richards, Wartime). In this type of research, creative imaginative flair is essential, Gibson argues. “We need to propose ‘what if’ scenarios that help us account for what has happened…so that we can better envisage what might happen. We need to apprehend the past” (Gibson, “Places” 2). To do this we need imagination, which involves “a readiness to incorporate the unknown…when one encounters evidence that’s in smithereens”, the evidence of the past that lies rooted in a seedbed of doubt (Gibson, “Places” 2). The sociologist, Avery Gordon, also argues in favour of the imaginative impulse. “Fiction is getting pretty close to sociology,” she suggests as she begins her research into the business of ghosts and haunting (Gordon 38). As we entertain our doubts we tune in with our uncertain imaginations. “The places where our discourse is unauthorised by virtue of its unruliness…take us away from abstract questions of method, from bloodless professionalised questions, toward the materiality of institutionalised storytelling, with all its uncanny repetitions” (Gordon 39). If we are to dig deeper, to understand more about the emotional truth of our “fictional” pasts we must look to “the living traces, the memories of the lost and disappeared” (Gordon ix). According to Janice Radway, Gordon seeks a new way of knowing…a knowing that is more a listening than a seeing, a practice of being attuned to the echoes and murmurs of that which has been lost but which is still present among us in the form of intimations, hints, suggestions and portents … ghostly matters … . To be haunted is to be tied to historical and social effects. (x) And to be tied to such effects is to live constantly in the shadow of doubt. A photograph of my dead baby sister haunts me still. As a child I took this photo to school one day. I had peeled it from its corners in the family album. There were two almost identical pictures, side by side. I hoped no one would notice the space left behind. “She’s dead,” I said. I held the photo out to a group of girls in the playground. My fingers had smeared the photo’s surface. The children peered at the image. They wanted to stare at the picture of a dead baby. Not one had seen a dead body before, and not one had been able to imagine the stillness, a photographic image without life, without breath that I passed around on the asphalt playground one spring morning in 1962 when I was ten years old. I have the photo still—my dead sister who bears the same name as my older sister, still living. The dead one has wispy fine black hair. In the photo there are dark shadows underneath her closed eyes. She looks to be asleep. I do not emphasise grief at the loss of my mother’s first-born daughter. My mother felt it briefly, she told me later. But things like that happened all the time during the war. Babies were born and died regularly. Now, all these years later, these same unmourned babies hover restlessly in the nurseries of generations of survivors. There is no way we can be absolute in our interpretations, Gibson argues, but in the first instance there is some basic knowledge to be generated from viewing the crime scene photographs, as in viewing my death photo (Gibson, "Address"). For example, we can reflect on the décor and how people in those days organised their spaces. We can reflect on the way people stood and walked, got on and off vehicles, as well as examine something of the lives of the investigative police, including those whose job it was to take these photographs. Gibson interviewed some of the now elderly men from the Sydney police force who had photographed the crime scenes he displays. He asked questions to deal with his doubts. He now has a very different appreciation of the life of a “copper”, he says. His detective work probing into these empty spaces, digging into his doubts, has reduced his preconceptions and prejudices (Gibson, "Address"). Preconception and prejudice cannot tolerate doubt. In order to bear witness, Gibson says we need to be speculative, to be loose, but not glib, “narrativising” but not inventive, with an eye to the real world (Gibson, "Address"). Gibson’s interest in an interpretation of life after wartime in Sydney is to gather a sense of the world that led to these pictures. His interpretations derive from his hunches, but hunches, he argues, also need to be tested for plausibility (Gibson, Address). Like Gibson, I hope that the didactic trend from the past—to shut up and listen—has been replaced by one that involves “discovery based learning”, learning that is guided by someone who knows “just a little more”, in a common sense, forensic, investigative mode (Gibson, “Address”). Doubt is central to this heuristic trend. Likewise, my doubts give me permission to explore my family’s past without the paralysis of intentionality and certainty. “What method have you adopted for your research?” Gordon asks, as she considers Luce Irigaray’s thoughts on the same question. It is “a delicate question. For isn’t it the method, the path to knowledge, that has always also led us away, led us astray, by fraud and artifice” (Gordon 38). So what is my methodology? I use storytelling meshed with theory and the autobiographical. But what do you think you’re doing? my critics ask. You call this research? I must therefore look to literary theorists on biography and autobiography for support. Nancy Miller writes about the denigration of the autobiographical, particularly in academic circles, where the tendency has been to see the genre as “self indulgent” in its apparent failure to maintain standards of objectivity, of scrutiny and theoretical distance (Miller 421). However, the autobiographical, Miller argues, rather than separating and dividing us through self-interests can “narrow the degree of separation” by operating as an aid to remembering (425). We recognise ourselves in another’s memoir, however fleetingly, and the recognition makes our “own experience feel more meaningful: not ‘merely’ personal but part of the bigger picture of cultural memory” (Miller 426). I speak with some hesitation about my family of origin yet it frames my story and hence my methodology. For many years I have had a horror of what writers and academics call “structure”. I considered myself lacking any ability to create a structure within my writing. I write intuitively. I have some idea of what I wish to explore and then I wait for ideas to enter my mind. They rise to the surface much like air bubbles from a fish. I wait till the fish joggles my bait. Often I write as I wait for a fish to bite. This writing, which is closely informed by my reading, occurs in an intuitive way, as if by instinct. I follow the associations that erupt in my mind, even as I explore another’s theory, and if it is at all possible, if I can get hold of these associations, what I, too, call hunches, then I follow them, much as Gibson and Gordon advocate. Like Gordon, I take my “distractions” seriously (Gordon, 31-60). Gordon follows ghosts. She looks for the things behind the things, the things that haunt her. I, too, look for what lies beneath, what is unconscious, unclear. This writing does not come easily and it takes many drafts before a pattern can emerge, before I, who have always imagined I could not develop a structure, begin to see one—an outline in bold where the central ideas accrue and onto which other thoughts can attach. This structure is not static. It begins with the spark of desire, the intercourse of opposing feelings, for me the desire to untangle family secrets from the past, to unpack one form, namely the history as presented within my family and then to re-assemble it through a written re-construction that attempts to make sense of the empty spaces left out of the family narrative, where no record, verbal or written, has been provided. This operates against pressure from certain members of my family to leave the family past unexplored. My methodology is subjective. Any objectivity I glean in exploring the work and theories of others comes through my own perspective. I read the works of academics in the literary field, and academics from psychoanalysis interested in infant development and personality theory. They consider these issues in different ways from the way in which I, as a psychotherapist, a doubt-filled researcher, and writer, read and experience them. To my clinician self, these ideas evolve in practice. I do not see them as mere abstractions. To me they are living ideas, they pulse and flow, and yet there are some who would seek to tie them down or throw them out. Recently I asked my mother about the photo of her dead baby, her first-born daughter who had died during the Hongerwinter (Hunger winter) of 1945 in Heilo, Holland. I was curious to know how the photo had come about. My curiosity had been flamed by Jay Ruby’s Secure the Shadow: Death and Photography in America, a transcript on the nature of post-mortem photography, which includes several photos of dead people. The book I found by chance in a second-hand books store. I could not leave these photographs behind. Ruby is concerned to ask questions about why we have become so afraid of death, at least in the western world, that we no longer take photographs of our loved ones after death as mementos, or if we take such photos, they are kept private, not shared with the public, for fear that the owners might be considered ghoulish (Ruby 161). I follow in Gordon’s footsteps. She describes how one day, on her way to a conference to present a paper, she had found herself distracted from her conference topic by thoughts of a woman whose image she had discovered was “missing” from a photo taken in Berlin in 1901. According to Gordon’s research, the woman, Sabina Spielrein, should have been present in this photo, but was not. Spielrein is a little known psychoanalyst, little known despite the fact that she was the first to hypothesise on the nature of the death instinct, an unconscious drive towards death and oblivion (Gordon 40). Gordon’s “search” for this missing woman overtook her initial research. My mother could not remember who took her dead baby’s photograph, but suspected it was a neighbour of her cousin in whose house she had stayed. She told me again the story she has told me many times before, and always at my instigation. When I was little I wondered that my mother could stay dry-eyed in the telling. She seemed so calm, when I had imagined that were I the mother of a dead baby I would find it hard to go on. “It is harder,” my mother said, to lose an older child. “When a child dies so young, you have fewer memories. It takes less time to get over it.” Ruby concludes that after World War Two, postmortem photographs were less likely to be kept in the family album, as they would have been in earlier times. “Those who possess death-related family pictures regard them as very private pictures to be shown only to selected people” (Ruby 161). When I look at the images in Ruby’s book, particularly those of the young, the children and babies, I am struck again at the unspoken. The idea of the dead person, seemingly alive in the photograph, propped up in a chair, on a mother’s lap, or resting on a bed, lifeless. To my contemporary sensibility it seems wrong. To look upon these dead people, their identities often unknown, and to imagine the grief for others in that loss—for grief there must have been such that the people remaining felt it necessary to preserve the memory—becomes almost unbearable. It is tempting to judge the past by present standards. In 1999, while writing her historical novel Year of Wonders, Geraldine Brooks came across a letter Henry James had written ninety eight years earlier to a young Sarah Orne Jewett who had previously sent him a manuscript of her historical novel for comment. In his letter, James condemns the notion of the historical novel as an impossibility: “the invention, the representation of the old consciousness, the soul, the sense of horizon, the vision of individuals in whose minds half the things that make ours, that make the modern world,” are all impossible, he insisted (Brooks 3). Despite Brooks’s initial disquiet at James’s words, she realised later that she had heard similar ideas uttered in different contexts before. Brooks had worked as a journalist in the Middle East and Africa: “They don’t think like us,” white Africans would say of their black neighbours, or Israelis of Arabs or upper class Palestinians about their desperately poor refugee-camp brethren … . “They don’t value life as we do. They don’t care if their kids get killed—they have so many of them”. (Brookes 3) But Brooks argues, “a woman keening for a dead child sounds exactly as raw in an earth-floored hovel as it does in a silk-carpeted drawing room” (3). Brooks is concerned to get beyond the certainties of our pre-conceived ideas: “It is human nature to put yourself in another’s shoes. The past may be another country. But the only passport required is empathy”(3). And empathy again requires the capacity to tolerate doubt. Later I asked my mother yet again about what it was like for her when her baby died, and why she had chosen to have her dead baby photographed. She did not ask for the photograph to be taken, she told me. But she was glad to have it now; otherwise nothing would remain of this baby, buried in an unfamiliar cemetery on the other side of the world. Why am I haunted by this image of my dead baby sister and how does it connect with my family’s secrets? The links are still in doubt. Gibson’s creative flair, Gordon’s ideas on ghostly matters and haunting, the things behind the things, my preoccupation with my mother’s dead baby and a sense that this sister might mean less to me did I not have the image of her photograph planted in my memory from childhood, all come together through parataxis if we can bear our doubts. Certainty is the enemy of introspection of imagination and of creativity. Yet too much doubt can paralyse. Here I write about tolerable levels of doubt tempered with an inquisitive mind that can land on hunches and an imagination that allows the researcher to follow such hunches and then seek evidence that corroborates or disproves them. As Gibson writes elsewhere, I tried to use all these scrappy details to help people think about the absences and silences between all the pinpointed examples that made up the scenarios that I presented in prose that was designed to spur rigorous speculation rather than lock down singular conclusions. (“Extractive” 2) Ours is a positive doubt, one that expects to find something, however “unexpected”, rather than a negative doubt that expects nothing. For doubt in large doses can paralyse a person into inaction. Furthermore, a balanced state of doubt fosters connectivity. As John Patrick Shanley’s character, the parish priest, Father Flynn, in the film Doubt, observes, “there are these times in our life when we feel lost. It happens and it’s a bond” (Shanley).

In view of the scarcity of literature data on the use of radiological imaging techniques in forensic veterinary medicine, while at the same time the number of reported crimes against animals involving the use of firearms is rising, this paper attempts to assess the usefulness of radiography and computed tomography (CT) in the post-mortem diagnosis of gunshot wounds (GSW) in comparison to classic necropsy. The design of the experiment was as follows: preparation of the research material (13 dog carcasses), shooting of the material from different distances (1.5 and 12 m, plus one contact shot to the head) and using different types of ammunition, followed by X-rays and CT scans in each case to examine the injuries resulting from the shot. The final steps of the experiment were photographic documentation and autopsy by the Virchow method. In the examined material, post-traumatic bone lesions and the presence of metallic foreign bodies were successfully imaged by both radiography and CT. GSW analysis using CT provided much better data quality and some additional information. Two general conclusions can be drawn from the results of the experiment. First, damage caused by gunshots is correlated with the calibre, initial velocity and kinetic energy of the projectile, as well as the distance from the muzzle of the gun to the object shot. Second, radiological examination is useful in preparing forensic veterinary opinions. Used as a complement to classic necropsy, they increase the possibility of an accurate post-mortem diagnosis of shooting victims.

PurposeForensic dentistry is the application of dentistry in legal proceedings that arise from any facts relating to teeth. The ultimate goal of forensic odontology is to identify the individual when there are no other means of identification such as fingerprint, Deoxyribonucleic acid (DNA), iris, hand print and leg print. The purpose of selecting dental record is for the teeth to be able to withstand decomposition, heat degradation up to 1600 °C. Dental patterns are unique for every individual. This work aims to analyze the contour shape extraction and texture feature extraction of both radiographic and photographic dental images for person identification.Design/methodology/approachTo achieve an accurate identification of individuals, the missing tooth in the radiograph has to be identified before matching of ante-mortem (AM) and post-mortem (PM) radiographs. To identify whether the missing tooth is a molar or premolar, each tooth in the given radiograph has to be classified using a k-nearest neighbor (k-NN) classifier; then, it is matched with the universal tooth numbering system. In order to make exact person identification, this research work is mainly concentrate on contour shape extraction and texture feature extraction for person identification. This work aims to analyze the contour shape extraction and texture feature extraction of both radiographic and photographic images for individual identification. Then, shape matching of AM and PM images is performed by similarity and distance metric for accurate person identification.FindingsThe experimental results are analyzed for shape and feature extraction of both radiographic and photographic dental images. From this analysis, it is proved that the higher hit rate performance is observed for the active contour shape extraction model, and it is well suited for forensic odontologists to identify a person in mass disaster situations.Research limitations/implicationsForensic odontology is a branch of human identification that uses dental evidence to identify the victims. In mass disaster circumstances, contours and dental patterns are very useful to extract the shape in individual identification.Originality/valueThe experimental results are analyzed both the contour shape extraction and texture feature extraction of both radiographic and photographic images. From this analysis, it is proved that the higher hit rate performance is observed for the active contour shape extraction model and it is well suited for forensic odontologists to identify a person in mass disaster situations. The findings provide theoretical and practical implications for individual identification of both radiographic and photographic images with a view to accurate identification of the person.

The onset of damage caused by the free-edge effect in plain-woven carbon fiber reinforced plastic (CFRP) specimens with an out-of-plane waviness under tension-tension fatigue loading is investigated. Numerical calculations show that interlaminar and intralaminar stresses close to the out-of-plane waviness are higher than the equivalent stresses at the surrounding edge regions. Using submodels, the influence of the chosen out-of-plane waviness can be better assessed. The free-edge effect of the considered specimens, which originates from stress gradients between plies of different orientation, is altered by the change in the stress field caused by the out-of-plane waviness. Large interlaminar stresses between plies of the same orientation are obtained, which contrasts with existing literature. In experimental fatigue testing it is found that cracks at the free edge appeared at the predicted locations, and after reaching crack saturation, in regions close to the out-of-plane waviness, interlaminar and intralaminar stresses lead to additional cracks along the whole free edges. The experimental tests are supported by a three dimensional image correlation system (3D-DIC), a thermal-imager and a digital photographic camera, which allows detailed examination of selected areas. Visual observation during fatigue testing and post-mortem inspection show good agreement between experimental data and numerical calculations in relation to the location of the damage initiation. As a result, out-of-plane waviness at free edges must be considered as an additional significant fatigue damage initiation location in laminate analysis.
