Rotor Yarn Structure by Cross-Sectional Microtomy
Textile Research Journal, 1988A mathematical model is suggested for studying the radial packing density of yarn, and the proposed model is used for a comparative study of ring and rotor spun yarns. The results show that rotor spun yarn consists of a smaller number of fibers in the cross section compared to ring spun yarn, which explains the lower strength of rotor yarn.

Cross-linked albumin as supporting matrix in ultrathin cryo microtomy
Journal of Ultrastructure Research, 1972A method is described by which tissue blocks and cell cultures can be rapidly encapsulated for cryoultramicrotomy. Bovine serum albumin, insolubilized with glutaraldehyde, has been found to be a good embedding medium for biological purposes. Ultrathin frozen sections with large fields that are sufficiently uniform for low and high magnification ...

Microtomy with a Reciprocating Circular Knife and a Mechanism for Sharpening the Knife
Review of Scientific Instruments, 1946The use of a circular reciprocating microtome knife is described along with a mechanism for sharpening the knife. A reduction of distortion in serial sections for embryological reconstructions is claimed and the physics involved noted. Related subjects are discussed and special emphasis is placed on the mechanics of sectioning with such a knife.
