BACKGROUND Penetrating neck injuries result from missiles and stab wounds. A gas pistol is a non-lethal weapon for self-defence. CASE REPORT We present a case where the use of a modified gun led to multiple injuries in a single shot. Four projectiles were embedded in the neck, one in the larynx and three in the cervical spine. The first was removed via a combined external and endoscopic appro...

the aim of this research was determination of nutritive value of cressa cretica with gas test method, in vivo digestibility and degradability with nylon bag method in three phenological stages. the amount of crude protein decreased significantly in seeding stage. but the amount of ndf and adf increased in seeding stage. the degradability of dry matter and rapid and slowly degradable fractions d...

OBJECTIVES One way law enforcement officers support firearm safety is by promoting the use of gun locks. This investigation examined law enforcement officers' willingness to use gun locks on their own guns, as well as their opinions regarding gun locks in general. SETTING Law enforcement officers from an urban agency in the southern region of the United States. METHODS Free keyed cable gun ...

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 The nail gun is a commonly utilized tool in carpentry and construction. When used properly with appropriate safety precautions, it can facilitate production and boost efficiency; however, this powerful tool also has the potential to cause serious injury. The most common site of nail-gun injuries in both industrial and nonoccupational settings is the hand. MATERIALS AND METHODS We r...

A new paradigm for an effective delivery of therapeutics into cancer cells is presented. Degradable porous silicon carriers, which are tailored to carry and release a model anti-cancer drug, are biolistically bombarded into in-vitro cancerous targets. We demonstrate the ability to launch these highly porous microparticles by a pneumatic capillary gene gun, which is conventionally used to delive...

Abstract The effect of rifling height on erosion for cannon barrel was studied in this paper. An velocity kernel function which is an Arrhenius type revealing thermal and chemical effects proposed. employed numerical simulations to obtain the depth after several rounds two kinds gun barrels at commencement full rifling. By comparing final depths obtained by firing tests, it can be concluded tha...

OBJECTIVE School-associated firearm violence among children and adolescents is a national public concern. The objective of this study was to determine the accessibility of firearms, methods of firearm access and firearm safety knowledge among middle and high school students in Orange County, California. METHODS After permission from school officials and parents was obtained, a 24-question sur...

A 60 kV neutral lithium diagnostic beam probes the edge plasma of JET for the measurement of electron density profiles. This paper describes recent enhancements of the diagnostic setup, new procedures for calibration and protection measures for the lithium ion gun during massive gas puffs for disruption mitigation. New light splitting optics allow...
