The principles of continuum mechanics provide a consistent
framework for the derivation of mathematical statements describing
transport of water and solute, and growth in plant tissue. These
derivations are based upon the explicit consideration of the tissue as
a mathematical continuum composed of a cell wall matrix, water, and
solute...
Three isolates of Escherichia coli were labeled by their resistance
to sodium azide and, separately, to novobiocin, nalidix acid, and tetracycline.
The strains exhibited a high degree of persistence in the soil
environment and were recoverable on strain specific media at levels
within the 95% confidence interval of the numbers...
Selenomethionine and methionine have been postulated to be similarly
involved in protein synthesis. This thesis has evaluated this
hypothesis from a molecular and genetic approach. Selenomethionine
and methionine were incorporated into rabbit reticulocyte hemoglobin
at the same rates and in equal quantities. Each methionine demonstrated
competitive inhibition for its analog...
Heat transfer measurements have been made from a long (L/D = 15)
horizontal cylinder in water parallel to a heated vertical wall. The
cylinder and wall boundary conditions were isothermal, and they were
maintained at equal temperatures. The investigation covered Rayleigh
numbers based on cylinder diameter from 400,000 to 10,000,000....
Studies were directed toward the formulation of a selective
Aeromonas medium that would permit the isolation of Aeromonas
species in the presence of other common bacterial flora. The final
composition of this medium, PBG Agar, in grams per liter, is:
Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5;
sodium...
