BACKGROUND Gun possession by high-risk individuals presents a serious threat to public safety. U.S. federal law establishes minimum criteria for legal purchase and possession of firearms; many states have laws disqualifying additional categories for illegal possession. METHODS We used data from a national survey of state prison inmates to calculate: 1) the proportion of offenders, incarcerate...

Objectives—One way law enforcement oYcers support firearm safety is by promoting the use of gun locks. This investigation examined law enforcement oYcers’ willingness to use gun locks on their own guns, as well as their opinions regarding gun locks in general. Setting—Law enforcement oYcers from an urban agency in the southern region of the United States. Methods—Free keyed cable gun locks were...

In this contribution we investigate the problem of linear velocity estimation of a Gun Launched Micro Air Vehicle (GLMAV), which is a new Micro Air Vehicle (MAV) concept, intended for outdoor flight, and using two-bladed coaxial contra-rotating rotors. The linear velocity estimation is realized using a simple time-varying Luenberger-like observer, and only using partial measurmements of an Iner...

This paper presents a novel interface for 3D modeling in augmented reality, aiming at developing a form gradually in the early phase of a product design process. Previous VR/AR based modeling systems have focused largely on geometrical algorithms and system performance issues. From a designers’ perspective, this study analyzed the conventional form creating processes and developed a more intuit...

Gunshot wounds are traumatic events that emergency departments around the country treat on a daily basis. An increasing number of these wounds are being caused by air rifles that shoot ball bearings (ie, BB guns) and, although uncommon, the results can be fatal. The general public and most practitioners may not realize the damage these "toys" can inflict. This article highlights an unfortunate ...

We review the status of indirect Dark Matter searches, focusing in particular on the connection with gamma-ray Astrophysics, and on the prospects for detection with the upcoming space telescope GLAST and Air Cherenkov Telescopes such as CANGAROO, HESS, MAGIC and VERITAS. After a brief introduction where we review the fundamental motivations for indirect searches, we tackle the question of wheth...

The tension was soft and there was no perception of light (Fig. 1). X-ray Localization.-A round foreign body 5 x 5 x 5 mm. was lying 1 mm. above the horizontal plane of the cornea, 21 * 5 mm. back from the centre of the cornea, and I 5 mm....

BACKGROUND Gun theft is an important source of guns used by criminals. Yet no empirical work has focused on the characteristics of gun owners that distinguish those who have had their guns stolen from those who have not. In this study, we examine the demographics and behavioral characteristics of gun owners who report having had a gun stolen. METHODS Data come from a nationally representative...

BACKGROUND Currently the standard femoral cementing technique requires cement injection gun to deliver bone cement into the femoral canal. The standard cement gun is expensive and must be imported. There is no previous study about the use of a household caulking gun for femoral cementation. OBJECTIVE To compare the radiographic quality of cementing technique in proximal femur between using st...
