Scapula Winging
A winged scapula (scapula alata) is a skeletal medical condition in which the shoulder blade protrudes from a person's back in an abnormal position. In rare conditions it has the potential to lead to limited functional activity in the upper extremity to which it is adjacent. It can affect a person's ability to lift, pull, and push weighty objects. In some serious cases, the ability to perform activities of daily living such as changing one's clothes and washing one's hair may be hindered. The name of this condition comes from its appearance, a wing-like resemblance, due to the medial border of the scapula sticking straight out from the back. Scapular winging has been observed to disrupt scapulohumeral rhythm, contributing to decreased flexion and abduction of the upper extremity, as well as a loss in power and the source of considerable pain. A winged scapula is considered normal posture in young children, but not older children and adults. Signs and symptoms The severity ...

Wing Foiling
Wing foiling or wing surfing or winging is a wind propelled water sport that developed from kitesurfing, windsurfing and surfing. The sailor, standing on a board, holds directly onto a wing. It generates both upward force and sideways propulsion and thus moves the board across the water. The recent development of foilboards, which plane very early on a hydrofoil fin and thereby lift off the water producing low friction, represent the ideal complementary hydrodynamic platform for wings. This young sport is poised to become wildly popular. History Precursors The history of wing foiling begins with the invention of wing surfing dating back to 1981, when aeronautical engineer Jim Drake, the inventor of windsurfing, and Uli Stanciu, European windsurfing pioneer, together invented the first wing. Their patented concept was based on the symmetrical shape of the flying fish. Unlike windsurfing, their wing was hand held and not fixed to the board via a mast. About the same time ...

Aerodynamic Flight
Flight or flying is the process by which an object (physics), object motion (physics), moves through a space without contacting any planetary surface, either within an atmosphere (i.e. air flight or aviation) or through the vacuum of outer space (i.e. spaceflight). This can be achieved by generating lift (force), aerodynamic lift associated with gliding flight, gliding or air propulsion, propulsive thrust, aerostatically using buoyancy, or by ballistics, ballistic movement. Many things can fly, from Flying and gliding animals, animal aviators such as birds, bats and insects, to natural gliders/parachuters such as patagium, patagial animals, anemochorous seeds and ballistospores, to human inventions like aircraft (airplanes, helicopters, airships, balloons, etc.) and rockets which may propel spacecraft and spaceplanes. The engineering aspects of flight are the purview of aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the atm ...

Shovel-shaped Incisors
Shovel-shaped incisors (or, more simply, shovel incisors) are incisors whose lingual surfaces are scooped as a consequence of lingual marginal ridges, crown curvature or basal tubercles, either alone or in combination. Shovel-shaped incisors are significantly common in Amerindians from North, Central and South America. They are also common in East and Central Asians, Hungarians, the Inuit and Aleut peoples of Northeast Asia and North America (including but not limited to the Inuit peoples of eastern Alaska, arctic Canada and Greenland). In European and African groups, shovel-shaped upper incisors are uncommon or not present. There is a spectrum of the degree of shoveled-ness, ranging on a scale from 0 to 7 of spatulate incisors to shoveled incisors. It was theorized that positive selection for shovel shaped incisors over the spatulate incisors are more commonly found in anthropoids within cultures that used their teeth as tools due to a greater structural strength in increased sho ...
