Dynamic Rheooptical Behavior of Isolated Bovine Cornea

The mucopolysaccharides of bovine cornea.

The mucopolysaccharides isolated from various mesodermal tissues have, in several instances, been shown to consist of complex mixtures, and not of single compounds as was believed formerly. In view of the rather contradictory findings reported in the literature, it was thought advisable to reinvestigate the mucopolysaccharide fractions of the cornea. In this paper, the separation of three disti...

Atomic force microscopic studies of isolated collagen fibrils of the bovine cornea and sclera.

Isolated collagen fibrils from the bovine cornea and sclera were investigated by atomic force microscopy (AFM) in a non-contact mode. AFM imaging visualized the surface topography of both corneal and scleral collagen fibrils with quantitative information on their height and width. The corneal collagen fibrils had a height of 15.6 +/- 1.5 nm and a D-periodicity of 63.9 +/- 0.5 nm. On the other h...

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...

The relation between hydration and mechanical behavior of bovine cornea in tension.

The cornea is a transparent soft tissue covering the front of the eye. The biomechanical properties of the cornea have been commonly investigated by uniaxial tensile and inflation testing methods. The cornea like many other hydrated tissue swells when immersed in an ionic solution. Previous studies on hydrated tissues have shown that mechanical properties and hydration are closely related. The ...
