We report an extensive set of two-dimensional MHD simulations exploring the role and evolution of magnetic fields in the dynamics of supersonic plasma clumps. We examine the influence of both ambient field strength and orientation on the problem. Of those two characteristics, field orientation is far more important in the cases we have considered with β0 = pg/pb ≥ 1. That is due to the geometry...

Background Paravertebral catheters are generally inserted and removed without complications. However, catheter breakage occurs rarely. This is the first report describing breakage of a thoracic paravertebral catheter and retention of the catheter fragment within the patient. Case presentation A 65-year-old female patient complained of an unusual sensation in her back during postoperative chem...

Bullet rosette particles are common in ice clouds, and the bullets may often be hollow. Here the singlescattering properties of randomly oriented hollow bullet rosette ice particles are investigated. A bullet, which is an individual branch of a rosette, is defined as a hexagonal column attached to a hexagonal pyramidal tip. For this study, a hollow structure is included at the end of the column...

Abullet located in the interventricular septum is shown in frontal (A) and right lateral (B) chest radiography and in an echocardiogram (C; RA indicates right atrium; RV, right ventricle; LA, left atrium; and LV, left ventricle. Superior white arrow, labeled BULLET, shows the bullet located at the interventricular septum). It is from a 37-year-old policeman who was shot while on duty. The bulle...

PURPOSE To determine whether plain film and CT findings help predict the presence and severity of vascular trauma. METHODS The records of 65 patients with gunshot wounds of the neck were reviewed. There were 58 men and 7 women ranging in age from 2 to 72 years. All had angiography of the cervical vessels; in addition, 64 had plain radiography, 22 had CT, and 14 had a barium swallow. The resul...

The operating principle of electromagnetic rail gun by store capacitor was analyzed. A simulation model about the bullet velocity in the electromagnetic rail gun was built. The results of computer simulation experiment showed the relationships between the bullet velocity and the capacitor charging voltage and the pellet mass. By ten coil targets, a new kind of measuring method for the bullet ve...

We describe an unusual case of a postoperative bone cyst resulting from a retained fragment of surgical glove. We highlight some of the problems associated with gloves and suggest ways of safeguarding against similar complications.

Godrej Security Solution Division has developed bullet resistant solutions like Bullet resistant doors, Mantraps, Bullet resistant screening for banks, and bullet resistant cabins etc which are designed as per the requirements mentioned in various standards like National institute of Justice (NIJ), Underwriters Laboratory (UL), etc. These agencies have established the performance criteria and c...

BACKGROUND Penetrating aortic trauma remains one of the most challenging injuries with a high mortality rate if left untreated, or if the surgical treatment is delayed. We present an uncommon case of a late diagnosed abdominal firearm injury, in which the bullet partially penetrated the wall of the aorta, creating a plug that prevented immediate death due to massive bleeding. CASE PRESENTATIO...
