A general term for any break in a rock attributable to tectonic forces, magma movement, thermal processes; glacial or erosional loading or unloading, and earth tides. (Exact causes of fractures are not always known.) They occur in all types of rocks. Incomplete fractures are cracks; a fault is a fracture zone along which movement occurs. Fractured-rock aquifers often have a fast, turbulent flow; are less isotropic and less homogeneous than porous media, and Darcy's law may not apply to them. Hydrogeologic investigations in fractured rock are usually either discrete studies (based on the careful measurement of each fracture) or continuum studies (which investigate the properties of large regions of the fractured material).
Leg dangles loosely, animal limps. Muzzle the animal with a strip of cloth if necessary. Carefully wrap the broken leg with newspaper for support as a temporary splint. Place him on plywood so that he can be carried without undue movement. Keep him warm with a blanket. Take him to your veterinarian as soon as possible
A break in a bone. See comminuted; compound; condylar; fissure; metacarpal; oblique; saucer; sesamoid; slab; spiral; simple; stress. See "Fractures" subsection of "Musculoskeletal System" in veterinary supplement for a more detailed explanation.
A break in the rock, the opening of which allows mineral-bearing solutions to enter. A "cross-fracture" is a minor break extending at more-or-less right angles to the direction of the principal fractures.
(frac´-ture) The way in which a mineral breaks, other than along planes of cleavage, e.g. conchoidal fracture. A crack, joint, fault, or other break in rocks. Any rupture in fast ice or pack ice, from a few meters to many kilometers in length. Deformation due to a momentary loss of cohesion or of resistance to differential stress and a release of stored elastic energy.
A general term to include any kind of discontinuity in a body of rock if produced by mechanical failure, whether by shear stress or tensile stress. Fractures include faults, shears, joints, and planes of fracture cleavage.
Fractures are often described by the appearance of the surface of the break in a piece of steel. Crystalline is bright and glittering, failure having developed along the cleavage planes of individual crystals and can be typical of brittle material. A silky fracture has a smooth dull grain indicative of ductile material such as a mild steel. In tensile testing fractures are described by shape, e.g. cup and cone.
A break in bone or cartilage. Although usually the result of trauma, a fracture can be caused by an acquired disease of bone such as osteoporosis or by abnormal formation of bone in a disease such as osteogenesis imperfecta ("brittle bone disease"). Fractures are classified according to their character and location as, for example, a greenstick fracture of the radius. See the entire definition of Fracture
a break in a bone. giant cell arteritis (Also called cranial arteritis, temporal arteritis, or Horton's disease.) - disease causing inflammation of the temporal arteries and other arteries in the head and neck, causing the arteries to narrow, reducing blood flow in the affected areas; may cause persistent headaches and vision loss;
The breaking or chipping of a stone along a direction other than a cleavage plane. ull-cut Brilliant A brilliant-cut diamond or coloured stone with the usual total of 58 facets, consisting of 32 facets and a table above the girdle and 24 facets and culet below.
A fracture is a break in the bone or cartilage. It usually is a result of trauma. It can, however, be a result of disease of the bone, such as osteoporosis, or an abnormal formation of the bone in rare congenital (from time of birth) diseases, such as osteogenesis imperfecta. Fractures are classified by their character and location. Examples of classification include "spiral fracture of the femur", "greenstick fracture of the radius", "impacted fracture of the humerus", "linear fracture of the ulna", "oblique fracture of the metatarsal", "compression fracture of the vertebrae", and "depressed fracture of the skull". Fractures are also named by the trauma event that caused the bone breakage. Examples include "boxer's fracture" of the metacarpal bone of the hand, "blowout fracture" of the bones behind the eye, and "stress fracture" of the bones of tibia. Some fractures are also named by conditions associated with the bone breakage.
Fracture is a 2004 New Zealand film written and directed by Larry Parr and based on the novel by Maurice Gee. The film is set in Wellington and stars Kate Elliot, Jared Turner and Australian John Noble.
