The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
Epiphysiodesis is a pediatric orthopedic surgery procedure that aims at altering or stopping the bone growth naturally occurring through the growth plate also known as the physeal plate. There are two types of epiphysiodesis: temporary hemiepiphysiodesis and permanent epiphysiodesis. Temporary hemiepiphysiodesis is also known as guided growth ...
Child bone fracture. A child bone fracture or a pediatric fracture is a medical condition in which a bone of a child (a person younger than the age of 18) is cracked or broken. [1] About 15% of all injuries in children are fracture injuries. [2] Bone fractures in children are different from adult bone fractures because a child's bones are still ...
Old Sheffield Plate (or OSP) is the name generally given to the material developed by Thomas Boulsover in the 1740s, a fusion of copper and silver which could be made into a range of items normally made in solid silver. [1] The material rapidly gained popularity as a substitute for solid silver, as it was much cheaper to produce.
Pelso Plate – Small tectonic unit in the Pannonian Basin in Europe. Timor Plate – Microplate in Southeast Asia carrying the island of Timor and surrounding islands. Tisza Plate – Tectonic microplate, in present-day Europe. Juan de Fuca Plate – Small tectonic plate in the eastern North Pacific – 250,000 km 2.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Vitreous enamel. Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy".
A typical arthropod exoskeleton is a multi-layered structure with four functional regions: epicuticle, procuticle, epidermis and basement membrane. [1] Of these, the epicuticle is a multi-layered external barrier that, especially in terrestrial arthropods, acts as a barrier against desiccation. The strength of the exoskeleton is provided by the ...
