چکیده

There are numerous techniques for sampling density gradients in experiments involving the preparative ultracentrifuge. Among the sampling procedures used are: drawing liquid samples from the top of the density gradient with modified pipettes (J. B. Sinclair et al., Phytopathology 47:372, 1957), displacement through the top of the density gradient (E. Huff, H. Oxley, and C. S. Silverman, J. Bacteriol. 88:1155, 1964), piercing the side of the density tube with a needle and

A Simple Freeze Fracture Technique for Scanning Electron Microscopy of Collagenous Biomaterials

A simple freeze fracture technique for the ultrastructural analysis of fragile collagenous biomaterials is presented. Following standard methods of preparation and dehydration, fragile biomaterials are fractured with a sharp blade attached to a modified slide hammer. The sliding mass imparts a sudden impact load on the frozen surface of the material , creating a distortion free cleavage plane a...

Three gradients and the perception of flat and curved surfaces.

Researchers of visual perception have long been interested in the perceived slant of a surface and in the gradients that purportedly specify it. Slant is the angle between the line of sight and the tangent to the planar surface at any point, also called the surface normal. Gradients are the sources of information that grade, or change, with visual angle as one looks from one's feet upward to th...

Rock Brittleness Prediction Using Geomechanical Properties of Hamekasi Limestone: Regression and Artificial Neural Networks Analysis

The cold climate is a favorable parameter for the development of tension cracks and decrease of rock brittleness. Therefore, this paper attempts to investigate the Hamekasi porous limestone in order to predict the brittleness indices during freeze-thaw cycles. The freeze–thaw test was executed for one cycle including 16 h of freezing, and 8 h of thawing. The geo mechanical properties and brittl...
