The Zeppelin-Lindau D.I had stressed skin fuselage and wings.. In mechanical engineering, stressed skin is a rigid construction in which the skin or covering takes a portion of the structural load, intermediate between monocoque, in which the skin assumes all or most of the load, and a rigid frame, which has a non-loaded covering.
Stiff skin syndrome (also known as "Congenital fascial dystrophy" [1]) is a cutaneous condition characterized by ‘rock hard’ induration, thickening of the skin and subcutaneous tissues, limited joint mobility, and mild hypertrichosis in infancy or early childhood. Immunologic abnormalities or vascular hyperactivity are not present in ...
In embryogenesis, the skeletal system is derived from the mesoderm germ layer. Chondrification (also known as chondrogenesis) is the process by which cartilage is formed from condensed mesenchyme tissue, which differentiates into chondroblasts and begins secreting the molecules (aggrecan and collagen type II) that form the extracellular matrix.
The difference between the unmodified and modified forms of chitinous arthropodan exoskeletons can be seen by comparing the body wall of say a bee larva, in which modification is minimal, to any armoured species of beetle, or the fangs of a spider. In both those examples there is heavy modification by sclerotisation.
The word skin originally only referred to dressed and tanned animal hide and the usual word for human skin was hide. Skin is a borrowing from Old Norse skinn "animal hide, fur", ultimately from the Proto-Indo-European root *sek-, meaning "to cut" (probably a reference to the fact that in those times animal hide was commonly cut off to be used as garment).
Inter-(from Latin inter 'between') is used to indicate something that is between. [15] For example, the intercostal muscles run between the ribs. Super-or Supra-(from Latin super, supra 'above, on top of') is used to indicate something that is above something else. [16] For example, the supraorbital ridges are above the eyes.
In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans ( butterflies and moths ), scales are plates on the surface of the insect wing , and provide coloration.
Contact between a rigid conical indenter and an elastic half-space In the case of indentation of an elastic half-space of Young's modulus E {\displaystyle E} using a rigid conical indenter, the depth of the contact region ϵ {\displaystyle \epsilon } and contact radius a {\displaystyle a} are related by [ 17 ]
