The Relative Desirability of Two Types of Junior College Operation
The problem of this study was to determine whether it is more desirable to operate a two-year college in the Dallas metropolitan area as a county college or to operate a two-year college under the administration of the Dallas Independent School District.

CHEMISTRY OF +1 IODINE IN ALKALINE SOLUTION
The iodine species formed either by adding hypochlorite to a basic iodide solution or by adding triiodide to sodium hydroxide, was identified as hypoiodite ion. The absorption spectrum of IO{sup -} was investigated in the wavelength range from 450 m{micro} to 280 m{micro}. The kinetics of the reaction I{sup -} + ClO{sup -} = IO{sup -} + Cl{sup -} was studied spectrophotometrically in alkaline solution. The forward rate law was found to be d(IO{sup -})/dt = k(I{sup -})(ClO{sup -})/OH{sup -}. At 25 C and an ionic strength of 1.00 M, k is 61 {+-} 3 sec{sup -1}. It was found spectrophotometrically that for certain ratios of the initial iodide to hydroxide concentrations, there was evidence of the presence of I{sub 3}{sup -}, I{sub 2}OH{sup -}, and I{sub 2}O{sup 2-} along with IO{sup -}. The equilibrium constants between IO{sup -} and these three species were evaluated by a graphical method. The formal potential of the cell: Pt:H{sub 2}:1 M NaOH : 1M NaOH, KI, NaIO : Au was found to be 1.297 v at 25 C. The equilibrium constant, K{sub 2} = (I{sub 3}{sup -})(OH{sup -}){sup 2}/(IO{sup -})(I{sup -}){sup 2}, of the reaction IO{sup -} + 2I{sup -} + H{sub 2}O …

Sanitary Engineering Aspects of Long-Range Fallout from Nuclear Detonations
From abstract: Results of a study of the sanitary engineering aspects of fallout from nuclear weapons are reported. Data were obtained from: a. Weekly surface water samples from 22 stations on streams and reservoirs in Eastern Massachusetts, collected from March, 1952 to July, 1953, and assayed for radioactivity. b. Weekly rain samples from March to July, 1953. c. Stream mud and soil samples collected before and after a large fallout. d. Results of fallout activity measurements by others based on samples from Massachusetts and the vicinity of Rochester, New York. Plots are presented showing the relations of the radiological data to the timing of detonations and the daily precipitation and showing daily deposition of activity and concentration in runoff. Runoff coefficients for fallout radioactivity are calculated.

Relative Yields of Nitrogen-17 Produced by 190-Mev Deuteron Bombardment
"Yields of N¹⁷ relative to that produced in LiF have been measured in the 190-Mev deflected deuteron and the 380-Mev alpha beams of the 184-inch synchrocyclotron. The measurements have been performed in all the light elements from 0 through V, with the exception of Sc and the noble gases. In addition, yields were measured in the separated isotopes of Mg...Comparisons are made with other types of yield studies performed with neutrons and protons, and the areas of agreement are noted."

The Method of Moments in Quantum Mechanics ; The [Pi]-Mesic Disintegration of the Deuteron
The following report contains two reports to summarize a thesis: first, a report describing the classical moment techniques of Tchebycheff, Markov, and Stieltjes that have been applied to the problem of diagonalizing the Hamiltonian operator; and the second report describes an investigation of the higher-order corrections to the mesic disintegration of deuterons that is considered.

Compton Scattering on Nucleons
From introduction: "The present paper deals with a classical calculation in which some of the meson effects can be included to all orders in the meson-nucleon coupling coupling constant, in particular those having to do with the gyration of the nucleon spin and isotopic spin. Such a treatment leads to results qualitatively different from the weak coupling calculations."

Capacity Factors in the Performance of Perforated Plate Distillation Columns
From abstract: "A study of factors affecting the vapor handling capacity of perforated plate liquid-vapor contacting columns. Vapor phase pressure drop across plates, liquid entrainment upward from plate to plate, and plate stability were investigated as functions of operational and geometric column parameters."

Production of Neutral Photopions as a Function of Atomic Weight
Thesis discussing the relative yield of neutral pions from elements in a reaction "as a function of the quantum-limit energy (the maximum energy of the quanta in the bremsstrahlung beam) of the Berkeley synchrotron." Interpretation of the results leads to values for the mean free path for absorption of the neutral pions in nuclear matter.

Analysis of the Interaction of 300-Mev Neutrons with Xenon
Abstract: And investigation of the interactions between 300-Mev neutrons and xenon was made by means of a cloud chamber in a pulsed magnetic field of 21,700 gauss placed in the neutron beam of the 184-inch Berkeley cyclotron. Eighty-seven negative pion events and 257 other stars were analyzed. In addition an experimental check was made on the energy of the incoming neutrons. Classification, identification, and angular and energy distributions of prongs associated with all events are presented. Interpretations of results are given.
