Surges in Southern Outfall Sewer and Flow Conditions in State Fairgrounds (Western Parkway) Pumping Plant, Louisville, Kentucky: Hydraulic Model Investigation

Description: Report of findings from various tests: "Model investigations of the surges occurring in sewer lines and of the flow conditions in a typical pumping plant, used to dispose of drainage during high river stages, were conducted as a part of the local flood protection project for Louisville, Kentucky. Studies conducted on a 1:32 scale simplified model of the Southern Outfall Sewer provided general information on the relative amount of relief from surges to be expected from the pumping station and manholes in the sewer line upstream" (p. v).

The Mechanism of Proton Polarization in High-EnergyCollisions

Description: Recently experimental evidence has accumulated showing that high-energy collisions of protons with various nuclei induce a considerable polarization in proton beams, and a mechanism has been proposed to account for this effect.

Chemical and Photochemical Reactions of Thioctic Acid and RelatedDisulfides

Description: The carbon cycle of photosynthesis is briefly reviewed in its entirety and the experiments involving it which led to the implication of disulfide rupture in photosynthesis are indicated. A review of the organic, physical and photochemistry of disulfides, with particular reference to the five-membered disulfide rings as they appear in thioctic acid, is given.

A Survey of the Rates and Products of Short-Term Photosynthesis inPlants of 9 Phyla

Description: The conclusions of this paper are: (1) Short-term photosynthetic experiments using C{sup 14}O{sub 2} and paper chromatography were performed with 27 different plants representing nine phyla: Schizophyta (Schizophyceae), Euglenophyta, Chlorophyta, Charophyta, Chrysophyta, Rhodophyta, Bryophyta, Pteridophyta, and Spermatophyta. (2) There is a remarkable uniformity in the types of ethanol-soluble compounds which became radioactive in the entire group of plants used. The amounts of the different compounds varied considerably percentage-wise among the various plants as would be expected because of their inherent metabolic differences and the variations in their physiological states induced by experimental conditions. (3) Sucrose became radioactive in very different amounts in two major groupings of plants: (a) those containing only photosynthetic tissue and (b) those containing non-photosynthetic tissue as well. The amount of radioactive sucrose in the former group was much lower than that in the latter. (4) An unidentified compound became radioactive in appreciable amounts in two of the blue-green algae, but was radioactive in very small amounts or not visible at all on the chromatograms of all other plants.

Correlation of Engineering Design with Preliminary OperationalExperience of the Bevatron Accelerator

Description: The precise relationship required between the frequency of the accelerating voltage and the magnetic field guiding particles accelerated in a high-energy proton synchrotron presents a challenging design problem ot the electronic engineer. In the University of California Bevatron, it has been necessary to develop a number of circuits whose performance follows a prescribed function to within better than one-tenth of one per cent. Control and monitoring of the acceleration cycle is carried on at a control area suitably shielded from high-energy radiation.

Behavior, a Balanced Network of Chemical Transformations(Biokinetics)

Description: While the concept of a biological system as a balanced network of chemical transformations is not a new one, experimental definition of specific systems has been lacking. This paper defines theoretically and experimentally a number of such networks and their behavior and response to some limited environmental changes.

Chemical Properties of Elements 99 and 100

Description: A description of some of the chemical properties and of the methods used in the separations of elements 99 and 100 is given. The new elements exhibit the properties expected for the tenth and eleventh actinide elements. Attempts to produce an oxidation state greater than 111 of element 99 have been successful. In normal aqueous media only the 111 state of element 100 appears to exist. The relative spacings of the elution peaks of the new elements in some separations with ion exchange resin columns are the same as the relative spacings of the homologous lanthanide elements. The results of experiments involving cation exchange resins with very concentrated hydrochloric acid eluant show that the new elements, like the earlier actinides, are more strongly complexed than the lanthanides. The new elements also exist partially as anions in concentrated hydrochloric acid, as do earlier actinide elements, and they may be partially separated from each other by means of ion exchange resins. With some eluants interesting reversals of elution positions are observed in the region Bk-Cf-99-100, indicating complex ion formation involving unusual factors.

The Chemistry of 1,2-Dithiolane (Trimethylene Disulfide) As aModel for the Primary Quantum Conversion Act in Photosynthesis

Description: Some chemical and photochemical observations of 1,2-dithiolane and its derivatives are reported with particular reference to the possible mode of function of the naturally occurring system, 6-thioctic acid. Experimental evidence is presented to demonstrate that the strain energy in this 5-membered ring is not less than 6.5 Kcals and probably larger. Reagents which both oxidize and reduce this ring are described together with the conditions required for its reformation from the corresponding dithiol. Evidence is adduced to indicate that the primary product of photolysis of this ring in acetic media is very likely a thiol and sulfenic acid or derivative thereof.
