It was 1871 when a baby boy was born in a tepee village on the Dakota grasslands. Hi s parents were Sioux and they named him Sitting B ull.

But after the battle he defended the actions of his people: “(…)We were camped there awaiting the will of the Great Spirit. praying to the Great Spirit to save us from the hands of our enemies.

  Injuries and fatalities occur in all forms of transportation but numerically road traffic accidents account for the great majority worldwide. In developed countries, they are the most common cause of death below the age of 50 years, and in young men this trend is even more marked. The pattern of injury, fatal and otherwise, varies considerably depending upon whether the victim is a vehicle occupant, a motorcyclist, a pedal cyclist or a pedestrian.     A number of elementary physical facts help to explain the complex pattern of traffic injuries, especially those sus- tained by the occupants of a vehicle.    o     Tissue injury is caused by a change of rate of movement. A constant speed, however rapid, has no effect whatsoever as is evident from space travel or the rotation of the earth. It is the change of rate that is traumatic - that is, acceleration or deceleration.  o     Change of rate is conveniently measured in 'graviti...

When the muzzle is held near the skin, but not actually in contact with it, a number of helpful signs are produced. Once again the appearance is naturally modified by clothing, which must always be carefully preserved and subjected to forensic scientific examination. Where clothing is present, then it will trap most, but not necessarily all, of the soot and powder grains. It will reduce the flame effects, though if the fabric is ignited even momentarily, this can diffusely scorch the skin. Assuming that the body surface is uncovered, a close discharge - one between actual contact and about 15 cm (6 inches) - is likely to show the following features: -           Singeing of hairs around the wound, unless the skin is hairless. The fine downy hairs of the trunk and limbs may be burnt away, though this is unlikely with dense, long, head hair. Where the distance is greater, the keratin of the hair may melt with the flame and then solid on cooling,...
