Fine Structure of Division
The mitotic, micronuclear division of the heterotrichous genus Blepharisma has been studied by electron microscopy. Dividing ciliates were selected from clone-derived mass cultures and fixed for electron microscopy by exposure to the vapor of 2 % osmium tetroxide; individual Blepharisma were encapsulated and sectioned. Distinctive features of the mitosis are the presence of an intact nuclear en...

متن کاملFine Structure of Cell Division in Chlamydomonas Reinhardi
Cell division in log-phase cultures of the unicellular, biflagellate alga, Chlamydomonas reinhardi, has been studied with the electron microscope. The two basal bodies of the cell replicate prior to cytokinesis; stages in basal body formation are presented. At the time of cell division, the original basal bodies detach from the flagella, and the four basal bodies appear to be involved in the or...
متن کاملFine-Grain Time Division Multiplexing in FPGAs
Increase in FPGA capacity combined with CMOS technology scaling has resulted in increased demands on the configurable wiring architecture. Modern FPGAs typically give over 50% of the reconfigurable area over to routing resources. Rent’s Rule [1,2] implies that static FPGA wiring is not scalable and we are approaching the point where cross chip communication is impossible within a clock cycle. I...
متن کاملFine structure of Vibrio cholerae during toxin production.
The fine structural changes associated with cell growth and toxin production have been examined in Vibrio cholerae strain 569B. No morphological alterations in the cell envelope are apparent during logarithmic growth with thin-section techniques. However, internal swelling, suggesting alteration of cell envelope permeability, is evident particularly during the late logarithmic and early station...
