Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios. 相似文献

Stab wounds were made in parenchymatous organs (e.g. liver, spleen, kidneys, lungs) using a variety of instruments. The shape of the resulting canal was investigated by X-ray analysis after introduction of an X-ray contrast medium. The best contrast was obtained using a contrast medium containing barium. The shape of the canal gave a direct representation of the outline of the instrument used. The width of the canal was however, always several millimeters smaller than the corresponding blade of the instrument. The position of the blade back in single-edged blades could be demonstrated with stronger contrast. 相似文献

In many states, legal representation for parents of dependent children is inadequate and can be a source of delays in securing permanency for children and unnecessarily protracted court proceedings. Often, such parents also face barriers to accessing services and independent evaluators. These issues are being addressed in the state of Washington through two approaches. The first is a successful enhanced legal representation program that has substantially improved case outcomes. The second is a statewide committee using innovative means to examine systemic responses to the challenges of the Adoption and Safe Families Act. 相似文献

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process. 相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

In this essay I examine the criminal defense file. I argue that being a largely neglected “object” of the legal field, upon
a close examination, the file discloses its intriguing materiality as what is predicated on the structure of the fold that
allows for the objective, virtual, and narrative spheres to overlap in a specific act-object, which, with Gilles Deleuze,
I call objectile. A subsequent phenomenological analysis of the legal file as objectile shows how its constitutive features help the attorney
shape ordinary matters into plentiful matters, turning the file into a locally designed sign system. Once exposed, this system
reveals its relations to the legal system at large, with individual activities, institutional practices, and legal procedures
all being a part of a complex manifold that is law. 相似文献
