The finite-difference computation of natural convection in a rectangular enclosure
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1966-01)
A study is made of the natural convection of a fluid contained in a long horizontal enclosure of rectangular cross section with one vertical wall heated and the other cooled. Two-dimensional motion is assumed. The governing ...
in vivo steroid biogenesis and metabolism in the human term placenta 2. in situ placental perfusion with cholesterol-7[alpha]-3H
(Elsevier, 1966-11)
Two human term placentas have been perfused with cholesterol-7[alpha]-3H. The perfusions were carried out at the time of elective repeat cesarean section and tubal ligation in term pregnancies. The major tritiated steroid ...
Interaction of concanavalin A, a phytohemagglutinin, with model substrates
(Elsevier, 1966-05-26)
Optical rotatory dispersion and absolute configuration--V. : The absolute configuration of natural plasmalogen
(Elsevier, 1966)
The 1-alkenylglycerol (III) and 1-alkylglycerol (II) obtained from natural plasmalogen (I) have been shown by optical rotatory dispersion measurements to have the same absolute configuration as natural chimyl and batyl ...
Theoretical study of bubble dynamics in purely viscous fluids
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1966-09)
This paper analyzes the growth or collapse of a spherical bubble in an incompressible, viscous fluid. Theoretical results include the timewise variations in the bubble size and its growth or collapse rate, the fluid pressure, ...
The condensing of low pressure steam on vertical rows of horizontal copper and titanium tubes
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1966-01)
Heat transfer data are presented for condensing steam at 2 in. Hg absolute pressure on the outside of nine copper and nine titanium horizontal tubes in a vertical row. The condensing coefficient correction factor was maximum ...
Concerning the molecular weight, shape, and size of polyglucose isolated from HeLa cells
(Elsevier, 1966-01-04)
Light-scattering measurements were made on a preparation of polyglucose isolated from HeLa cells. The molecular weight was determined, from a Zimm plot of the data, to be 4.6[middle dot]106. The character of the angular ...
Seed germination studies II. Pathways for starch degradation in germinating pea seedlings
(Elsevier, 1966-07-06)
Amylase activity is present in extracts of the axis tissue of etiolated pea seedlings. Several lines of evidence establish that this starch-hydrolyzing activity is due to the presence of a [beta]-amylase ([alpha]-1,4-glucan ...
