Traction substation: A traction substation or traction current converter plant is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current.Dynamic strain aging: Although sometimes dynamic strain aging is used interchangeably with the Portevin–Le Chatelier effect (or serrated yielding), dynamic strain aging refers specifically to the microscopic mechanism that induces the Portevin–Le Chatelier effect. This strengthening mechanism is related to solid-solution strengthening and has been observed in a variety of fcc and bcc substitutional and interstitial alloys, metalloids like silicon, and ordered intermetallics within specific ranges of temperature and strain rate.Posterior vitreous detachment: A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina.Placental expulsion: Placental expulsion (also called afterbirth) occurs when the placenta comes out of the birth canal after childbirth. The period from just after the baby is expelled until just after the placenta is expelled is called the third stage of labor.Mechanobiology: Mechanobiology is an emerging field of science at the interface of biology and engineering. It focuses on the way that physical forces and changes in cell or tissue mechanics contribute to development, physiology, and disease.Poecilia sphenops: Poecilia sphenops is a species of fish, of the genus Poecilia, known under the common name molly; to distinguish it from its congeners, it is sometimes called short-finned molly or common molly. They inhabit fresh water streams and coastal brackish and marine waters of Mexico.Vitreous membrane: The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically.Optic disc pit: An optic disc pit is a congenital excavation (or regional depression) of the optic nerve head resulting from a malformation during development of the eye. Optic pits are important because they are associated with posterior vitreous detachments (PVD) and even serous retinal detachments.Focal adhesionPars plana: The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long, located near the point where the iris and sclera touch and is scalloped in appearance.Friction burnCervical fractureFemoral fractureSodium polyacrylateScoliosis Research SocietyMechanochemistry: Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g.Hip spica cast: A hip spica cast is a sort of orthopedic cast used to immobilize the hip or thigh. It is used to facilitate healing of injured hip joints or of fractured femurs.Joint dislocationCell adhesionHaptotaxis: Haptotaxis (from Greek ἅπτω (hapto, "touch, fasten") and τάξις (taxis, "arrangement, order")) is the directional motility or outgrowth of cells, e.g.Neuro-ophthalmology: Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field.Peripheral nerve injury classification: Classification of peripheral nerve injury assists in prognosis and determination of treatment strategy. Classification of nerve injury was described by Seddon in 1943 and by Sunderland in 1951.Vinculum (ligament): In anatomy, a vinculum (pl. vincula) is a band of connective tissue, similar to a ligament, that connect a flexor tendon to a phalanx bone.Pedicure: A pedicure is a superficial cosmetic treatment of the feet and toenails. It provides a similar service to a manicure.Bakri balloon: The Bakri™ Balloon http://www.cookmedical.TSOM: Through-Focus Scanning Optical Microscopy (TSOM) is an imaging method that produces nanometer-scale three-dimensional measurement sensitivity using a conventional bright-field optical microscope. TSOM has been introduced and maintained by Ravikiran Attotahttp://www.Extracellular matrix
