CHEMISTRY OF +1 IODINE IN ALKALINE SOLUTION

Description: 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 … more

Thermal Conductivity and Viscosity of Gas Mixtures

Description: Correlations based upon empirical modified equations derived from kinetic theory were developed for the thermal conductivity and viscosity of gas mixtures. The conductivity equation was compared to 226 binary mixture conductivities in temperatures from 0 to 774 deg C from the literature and this work. The average deviation is 2.1%. In correlating conductivity data of mixtures of polyatomic molecules, the energy transport is considered in two parts, i.e., one protion transferred by collision and… more

Spallation-Fission Competition in Neptunium Compound Systems. Decay-Scheme Studies

Description: The results of a radiochemical study of fission and spallation products induced in U/sup 234/, U/sup 235/, and U/sup 236 and spallation products induced in U/sup 238/ by deuterons of less than 24 Mev are presented. The (d,n) reactions are interpreted as the result of direct interactions between the deuteron and the target nuclei, while the (d,n) reactions are thought to be taking place primarily by compound-nucleus mechanisms. A method for predicting the peak values of the cross section for (d,… more

On the Photofission Cross Sections Near Threshold of Nuclei in the Region of the Very Heary Elements

Description: Variations in the photofission cross section near ''threshold'' with initial kind of nucleus were investigated for seven spheroidal nuclei in the region of atomic numbers 90, 92, 93. The photofission cross sections at the two discrete energies 6.14 and 7.0 Mev were determined for the following even-even nuclide . Th/sup 232/, U/sup 234/, U/;sup 236/, and U/sup 238/; and also the odd- A nuclides. U/sup 233/, U/sup 235/ and Np/sup 237/. Nuclear excitation of the target nuclei was achieved via gam… more

A Study of the Effects of Elevated Temperatures on the Growth and Inheritance of Saccharomyces Cerevisiae

Description: A comparative study was made of the growth of yeast in various media at the optimum temperature (30 ) and at supraoptimum temperatures. It was found that at elevated temperatures there is a decrease in the ability of yeast to grow, which may be alleviated by increasing the percentage of yeast extract in the medium, adding oleic acid to the medium, or using an inoculum of cells that have previously been grown at the elevated temperature. Because of these findings, it is believed that growth at e… more

The Radiation Chemistry of the Symmetrical Dichloroethylenes

Description: Purified, degassed samples of cis- and trans-1,2dichloroethylene were irradiated in glass cells with 48Mev helium ions at energy inputs up to 10/sup 21/ ev/cc. The principal volatile radiolysis products are acetylene, hydrogen chloride, chloroacetylene, vinyl chloride, hydrogen, and dichloroacetylene, in order of decreasing yield. The use of a mass spectrometer in conjunction with gas chromatography made possible the identification of several higher-boiling, or ''polymer,'' products as tetrachl… more

[Chemistry Thesis] Part 1: The Spectra of Some Aliphatic Aldehydes and Their Monodeutero Derivatives,

Description: BS>An investigation of the infrared and near-ultraviolet spectra of three aliphatic aldchydes and their monodeutero derivatives is described. The infrared spectra of the acetaldehydes (CH/sub 3/CHO and CH/sub 3/CDO) were in agreement with work reported recently. A few new bands are reported and discussed. The infrared spectra of C/sub 2/H/sub 5/CHO, C/sub 2/H/sub 5/CDO, C/ sub 3/H/sub 7/CHO, and C/sub 3/H/sub 7/CDO at 450 to 4000 cm/sup -1/ were observed, and an assignment of the observed bands… more

Angular Distribution of Photopions From Hydrogen

Description: ABS>An accurate measurement of the differential cross section for the photoproduction of positive pions was made at the Berkeley synchrotron, for photon energies of 280 and 290 Mev. The mesons were produced in a thin-walled liquid hydrogen target, and the meson detection apparatus utilized the characteristic pi -- mu decay of the meson. The measurements were done in two steps, from 0 to 50 deg with equipment specifically designed to reduce a very high positron background, and from 30 to 160 deg… more

Free Convection Heat Transfer to Horizontal Cylinders From an Ordinary Fluid Containing a Volume Heat Source

Description: Outside heat transfer coefficients for several horizontal tubes cooling an ordinary fluid containing a volume heat source by free convection were obtained experimentally. Water was used as the coolant, and a very dilute solution of HC1 was the bulk fluid. The basic equipment included a Lucite test cell which contained the bulk fluid, Cu screen grids through which an alternating current was passed to generate a volume heat source in the bulk and several horizontal 1/4 in. O.D. stainless steel tu… more

Nuclear Reaction Mechanisms in the Heavy-Element Region

Description: Angular distributions of the heavy recoils produced in the ( alpha ,2n), ( alpha ,3n), ( alpha ,4n), ( alpha ,t), (d,n), (d,2n), (d,3n), and (d,p) reactions of Bi/sup 209/ have been measured at various incident-particle energies. The mechanisms of the ( alpha ,2n), ( alpha ,3n), and (d,3n) reactions have been inierpreted by comparison of these angular distributions with theoretical angular distributions resulting from Monte Carlo calculations based on a simple evaporation model.

Some Problems in Horizontal Two-Phase Tow-Component Flow

Description: An experimental investigation was conducted on the flow of air-water mixtures in a number of horizontal rectangular Lucite test sections, whose aspect ratios varied from two to sixteen. These test sections were assembled in various combinations to permit the study of the effect of a sudden change in flow area on the significant flow parameters. A technique was developed for measuring the volume fraction of each phase, making use of the difference of the attenuation characteristics of the liquid… more

Preliminary Testing of a Proportional Counter for Neutron Spectroscopy With Helium-3

Description: The He/sup 3/(n,p)T reaction can be utilized in a proportional counter for neutron-energy determination in the region 100 kev to 1 Mev. This has already been demonstrated and the reaction cross section in this energy region has been measured with a counter. For practical application of the counter as a spectrometer, such as in health physics work, it is desirable to increase the counter efficiency. A proportional counter utilizing an anticoincidence ring to reduce wall effect has been construct… more

The Deuteron-Pickup Reaction in an Optical-Model Approximation

Description: in which the nuclear interactions of the incoming and outgoing particles are considered. Two different formal expressions that give the transition amplitude are derived, and the wave functions in this amplitude are approximated by an optical-model procedure in which it is assumed that the initial- and final- state particles scatter elastically in the nucleus. The inelasticscattering effects are shown to be small. Several closed forms for these optical-model wave functions are derived on the hsi… more

[Chemistry Thesis] Part 2: High Intensity Light Sources

Description: A stable carbon arc operated in controlled atmosphere is described. The arc was designed to serve as a light source during lifetime studies of the B/sup 2/ SIGMA state of the CN molecule. The CN radiation from the plasma of the arc was investigated and found to have a brightness temperature of 5500 icient laborato K at lambda 3883 A. This is considerably higher than an estimate of the value required for lifetime measurements. The stability of the carbon arc under various conditions is discussed… more

Maria Edgeworth as a Precursor of Realism

Description: The purpose of this thesis is to study the novels of Maria Edgeworth in an attempt to discover whether or not her novels have merit beyond their representation of the manners and morals of her historical period. This involves first an examination of her novels in the light of such criticism as has given rise to the question of their importance.
