ELEPHANT CONTRACEPTION IS INCREASINGLY being identified as a solution to the problem of growing elephant numbers in conservation areas. As a result, it is now being incorporated into elephant management and policy in South Africa. We point out that elephant contraception may have numerous physical, social and ecological side-effects. These side-effects should be identified in advance and their ...

Results of studying the glow that occurs when a bullet passes through ballistic gel are presented. This phenomenon is all more interesting as in various areas gel, including those have not contacted directly with bullet. The emission spectrum consists mainly continuous component atomic lines superimposed on it. can be explained different ways: one options thermal radiation; however, description...

Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullet geometry is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions have been analysed by physically sectioning bullets – an approach which rules out any subsequent...

Megacity growth in the developing world is fueled by a desire to access their large local labor markets. Growing megacities suffer from high levels of traffic congestion and pollution, which degrade local quality of life. Transportation technology that allows individuals to access the megacity without living within its boundaries offers potentially large social benefits, because individuals can...

Bronchopulmonary dysplasia (BPD) continues to be the most common and most important complication in preterm infants with RDS. The incidence varies from 20 to 60 % in preterm infants whose weight are < 1500 gram. The presence of BPD is often associated with significant mortality and short term and long term morbidity, including growth failure and neurodevelopment delay. The exact mechanism and p...

It was Claude Bernard, a French physician and physiologist, who first correlated pain with sympathetic nervous system in the mid1800’s [1]. The first detailed descriptions of sympathetically-mediated pain came from one of his students, Silas Weir-Mitchell, in his book “Gunshot Wounds and other Injuries of Nerves”, published in 1864 [2]. During the American Civil War, Mitchell noted that some so...

Analytic philosophers have until recently heen reluctant to investigate the complex historical roolc; of their own philosophical tradition. Slowly, but surely, however, the necessary work is being done, and it is interesting in this respect that not only the Anglo-Saxon hut also the Continental roots of analytic philosophy are heing usefully illuminated .2 For as Michael Dummett points out in h...

The 3D shape and position of objects inside the human body are commonly detected using Computed Tomography (CT) scanning. CT is an expensive diagnostic option in economically disadvantaged areas and the radiation dose experienced by the patient is significant. In this dissertation, we present a technique for reconstructing the 3D shape and position of bullets from multiple X-rays. This techniqu...

An unusual case of head injury with a direct bullet injury to the pituitary gland is described. The hormonal profile one month after the injury showed severe panhypopituitatism which did not improve one month after surgical removal of the intrasellar bullet fragment.
