Electron-microscope observations of mitosis and cytokinesis in multinucleate protoplasts of soybean.
Multinucleate soybean protoplasts produced by spontaneous fusion during enzyme digestion of the cell wall initiated cell division after approximately 40 h in culture. The structure of these protoplasts during mitosis and cytokinesis was studied with both light and electron microscopes. Most nuclei did not fuse but divided synchronously. Interphase nuclei was commonly connected by short narrow n...
In order to study the effect of different gap ratios on thermofluid-dynamic field around a bluff body located in proximity heated wall, series experiments and numerical simulations have been conducted. The former were carried out using an open circulating water tank experimental platform single cylinder square column as geometrical models (their characteristic length being D). latter based well...
Streiblová, Eva (Czechoslovak Academy of Sciences, Prague, Czechoslovakia), I. Málek, and K. Beran. Structural changes in the cell wall of Schizosaccharomyces pombe during cell division. J. Bacteriol. 91:428-435. 1966.-Individual stages of growing and dividing cells of Schizosaccharomyces pombe were studied by means of fluorescence and electron microscopy with the use of metal-shadowed isolated...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
This study investigates color perception in a scene with two different illuminants. The two illuminants, in opposite corners, simultaneously shine on a (simulated) scene with an opaque dividing wall, which controls how much of the scene is illuminated by each source. In the first experiment, the height of the dividing wall was varied. This changed the amount of each illuminant reaching objects ...
BACKGROUND Breast reconstruction with pedicled transverse rectus abdominis myocutaneous (TRAM) flap can result in significant abdominal wall donor-site morbidity. We present our technique of transversely dividing the anterior fascia and rectus abdominis combined with reinforcement above the arcuate line for closure of the anterior abdominal wall defect to prevent contour deformities performed b...
