In warfare, airports can become the focus of intense fighting, for example the Battle of Tripoli Airport or the Battle for Donetsk Airport, both taking place in 2014. An airport primarily for military use is called an airbase or air station. Most of the world's airports are owned by local, regional, or national government bodies.
Age of viability. The age at which a premature baby can survive outside of the uterus. The age of viability occurs sometime between 22 and 26 weeks, usually when the weight is greater than 500 grams. The probability of survival is slim at 22-23 weeks, but increases to approximately 85% at 26-28 weeks. Respiratory problems are the most common complications that a preterm infant experiences.
How do I read my results? The T-score: The âyoung normalâ or T-score indicates how your BMD compares to that of a healthy 30 year-old. Peak bone density is reached by age 30 and should ideally be maintained at this level throughout your life. As BMD decreases from this peak density, fracture risk increases.The T-score is in units of standard deviations (SD) and shows whether your bones are more dense (+) or less dense (-) than those of a 30 year-old. This is the most important value and the one that is used to interpret what your BMD means.s BMD decreases from this peak density, fracture risk increases.
