Van Den Berghe Dequeker syndrome, also known as ulnar hypoplasia-split foot syndrome is a very rare congenital limb malformation syndrome which is characterized by severe ulnar hypoplasia, absence of the index to pinky finger in both hands, and split-foot.
Dislocation creep is a deformation mechanism in crystalline materials.Dislocation creep involves the movement of dislocations through the crystal lattice of the material, in contrast to diffusion creep, in which diffusion (of vacancies) is the dominant creep mechanism.
Creep or plastic deformation happens when subjected to intra-oral stresses such as chewing or grinding. Creep causes the amalgam to flow and protrudes from the margin of the cavity forming unsupported edges. "Ditch" is formed around the margins of the amalgam restoration after fracture due to amalgam creep at the occlusal margins.
When amalgam fillings are drilled for height adjustment, repair or replacement, some mercury-containing amalgam is inevitably washed down drains. (See Dental amalgam controversy - Environmental impact) When amalgam fillings are prepared by dentists, improperly disposed excess material may enter landfills or be incinerated. Cremation of bodies ...
An idealized uniaxial stress-strain curve showing elastic and plastic deformation regimes for the deformation theory of plasticity. There are several mathematical descriptions of plasticity. [12] One is deformation theory (see e.g. Hooke's law) where the Cauchy stress tensor (of order d-1 in d dimensions) is a function of the strain tensor ...
Manufacturers of baby powder and cosmetic products made with talc will have to test them for asbestos under a proposal announced by the U.S. Food and Drug Administration.
A foot deformity is a disorder of the foot that can be congenital or acquired. Such deformities can include hammer toe, club foot, flat feet, pes cavus, etc.
Dr. Smita Ramanadham, a plastic surgeon in New Jersey, added: “We see a loss of volume in the face [with weight loss], and when we lose fat in the face we see signs like the cheeks are more ...
