Sectioning of Soil

Vibratory microsurgical sectioning.

Today, the ready availability of finer instruments, suture material, and operating microscopes has provided the stimulus to further refinements in ophthalmic and other microsurgical techniques, where, only a decade ago, with adequate operative results from old techniques, interest could not be sustained in new ideas or inventions. The present paper describes the general features of a new vibrat...

Thin Sectioning: Details of Techniques

The study of cytological fine structure with the electron microscope, has as an important prerequisite, the ability to cut consistently good quality thin sections. Satisfactory techniques for doing this are well known in many laboratories and an excellent review of the subject has recently been published by Farquhar (1). However, some of the details of the practice of microtomy are not in the l...

Comprehensive approach to student sectioning

Student sectioning is the problem of assigning students to particular sections of courses they request while respecting constraints such as course structures, section limits, and reserved spaces. Students may also provide preferences on class times and course alternatives. In this paper, three approaches to this problem are examined and combined in order to tackle it on a practical level: stude...

Sectioning of tissue for electron microscopy.

A method of sectioning aspirated bone-marrow.

A technique for preparing histological sections of aspirated bone-marrow to be satisfactory should fulfil the following conditions: it should be simple and easy to perform; it should give a good concentration of marrow particles without much admixture with peripheral blood; it should produce very little lysis of the blood cells; and it should give good fixation of the tissue so that sections ca...
