Simulated chainsaw injury bone fracture data.

Forensic analysis is often required to determine the cause of an injury. Data for this purpose were acquired by simulating an injury to a limb inflicted by a chainsaw. A surrogate forearm was constructed from gel and a bone simulant.

Forensic application of inverse and reverse projection photogrammetry to determine subject location and orientation when both camera and subject move relative to the scene.

We present a case study of a mountain bicycle accident captured by the rider's chest-mounted action camera. The objective of the investigation was to determine the orientation of the bicycle relative to the ground and the location of the rider's center of gravity relative to the bicycle. The problem faced in the investigation was that the camera was moving relative to the scene and rider, and the bicycle was moving relative to the camera.

Methodology for determining accidental versus intentional injury afflicted by a chainsaw.

Forensic analysis is often required to determine whether an injury was inflicted intentionally or accidentally. We have developed a method for addressing this issue in the case of an injury to a limb inflicted by a chainsaw. We discuss the potential use of this methodology to the more general case of injuries inflicted by power tools.

Mechanical Aspects of Intervertebral Disc Injury and Implications on Biomechanics.

Study Design: This article comprises a review of the literature.

Objective: The purpose of this study was to elucidate the different types of structural failures exhibited in intervertebral discs (IVDs), summarize their potential causes with respect to mechanical loading conditions and the consequences on cell homeostasis and biomechanics.

Summary Of Background Data: Many studies have been performed to gain insight into how discogenic back pain progresses in humans both in vitro and in vivo as well as in animal disc models.

Police Officer performance and perception using light, medium and heavy weight tactical batons.

Objective: Compare the effectiveness of light, medium and heavy weight Police expandable batons from a performance and a user perception perspective.

Rationale: Police Officers are required to control combative individuals using less lethal tactics in proportion to the threat they face. Officers need to deliver sufficient force quickly and accurately.
