A case of a suicidal gunshot wound of the head where the projectile ricocheted within the calvarium and exited through the entrance wound is reported. Findings at the scene and from examination of the victim and the suspect weapon are presented and discussed.

Introduction Evaluation of the delivered dose of externally wedged photon beams by external diode dosimeters during the treatment process requires the estimation of exit surface dose correction factors in various wedge angles and field sizes. Materials and Methods A system of absorbed dose evaluation, using p-type diode dosimeters placed on the exit surface of a phantom, was characterized for e...

introduction: delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. according to icru, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. absorbed dose accuracy is investiga...

The incorporation of qualitative information into tracking systems is a challenging topic of research in the computer vision area. Within the context of an outdoor scenario, it is usual to find some patterns of human motion and, in general there is a reduced set of typical entrance and exit points. In this work we present a method to analyze an existing set of trajectories obtained in a selecte...

Pheromone-binding proteins (PBP) supply olfactory neuron cells with pheromones by binding the ligands they are tailored for and carrying them to their receptor. The function of a PBP as an efficient carrier requires fast ligand uptake and release. The molecular basis of the ligand-binding mechanism was addressed here for the intriguing case of the PBP of the silk moth Bombyx mori. This PBP comp...

Photoelectron-photofragment coincidence ~PPC! spectroscopy has been used to study the dissociative photodetachment of H2O2 2 and D2O2 . The observed partitioning of photoelectron and photofragment translational energies provides information on the dynamics in the transition state region of the reaction between two hydroxyl radicals: OH1OH→O(P)1H2O. The data reveal vibrationally resolved product...

The presentation explores diplophonia via numerical simulations of glottal vibrations. The aim of the study is to improve the understanding of glottal wall vibration and area waveform patterns of nonmodal phonation as observed via laryngeal highspeed videos. Diplophonia has been described as the simultaneous perception of two pitches during voicing. A broader definition is the vibration of diff...

Gap winds produced by a uniform airstream flowing over an isolated flat-top ridge cut by a straight narrow gap are investigated by numerical simulation. On the scale of the entire barrier, the proportion of the oncoming flow that passes through the gap is relatively independent of the nondimensional mountain height e, even over that range of e for which there is the previously documented transi...
