Studies On The Characterization And Activiation By Soluble Factor Of A Sodium-Activated, Magnesium-Dependent, Adenosinetriphosphatase In Rat Cerebral Cortex, Alan B. Forrest
University of the Pacific Theses and Dissertations
This study presented evidence for the existence of a membrane-bound, sodium-activated ATPase which does not require potassium ions for its activity. Furthermore, the data suggest the presence of a soluble factor which activates this enzyme and may play a regulatory role in sodium transport.

3,3-Diphenyl-2-Morpholinone Derivatives Of 2-Amino-2-Deoxy-D-Allose., Ram Babu
University of the Pacific Theses and Dissertations
A new cyclic protective group has been fused to the cis amino alcohol group of benzyl 2-amino-3,5-o-benzylidene-2-deoxyβ-D-Allopyranoside, by way of a unique rearrangements mechanism. To establish the 2-morpholinone structure, chemical studies, such as reduction and acetylation were conducted.
Comparative spectroscopic studies using ir, pmr, and C-13 nmr confirmed the assigned structures.
The 2-morpholinone ring was cleaved by mild alkaline hydrolysis and could be closed again with acetic anhydride in pyridine. An oxazolidinone derivation of benzyl 2-amino-4,6-o-benzylidene-2-deoxyβ-D-allopyranoside was prepared in a quantitative yield by a modification of a known method.
Protective group properties of the oxazolidinone were studied prior to the …

Horace W. Slocum Journals - Accession 23, Horace W. Slocum
Manuscript Collection
The Horace W. Slocum Journals include handwritten and typewritten accounts of Mr. Slocum’s journeys through South Carolina, North Carolina, Pennsylvania, Virginia, New York, Illinois, New Hampshire, and other states in search of rocks and minerals. Of special interest are photographs and maps of geological and mining sites in the typewritten, edited version of the journals. There is also a map index. The journals extend mainly from 1938 to 1956.
Inclusion Of Rectangular And Triangular Geometries In The Space-Dependent Kinetics Code, Fx2, Ted Perry
Inclusion Of Rectangular And Triangular Geometries In The Space-Dependent Kinetics Code, Fx2, Ted Perry
Undergraduate Honors Capstone Projects
The computer code FX2 is used to model liquid-metal fast-breeder reactors now being developed by the U. S. Atomic Energy Commission. These reactors differ from thermal reactors in that they have no moderator material in their cores and thus operate at mean neutron energies of 100 keV or more as opposed to neutron energies of less than 1 keV for thermal reactors. Also these reactors have the advantage that as a consequence of the high neutron energies, these reactors can be used to "breed" their own fuel: enriched 238U placed in the core is changed into plutonium which can …
