THE (5-PHENYL-2-OXAZOLYL)PYRIDINES AS FLUORESCENT pH INDICATORS. AN APPLICATION TO CHEMICAL RADIATION DOSIMETRY

Description: The three isomeric (5-phenyl-2-oxazolyl)pyridines have been shown to be sensitive fluorescent pH indicators which show a pronounced change to increased visible fluorescence as the pH is lowered. Absorption and fluorescence spectral data and pK values are given. Selective excitation of fluorescence from the conjugate acid in the presence of the free base was found possible. The sensitivity of the 4-isomer was demonstrated to be adequate for determining the small amounts of acid produced in certa… more

Aerodynamic Characteristics at a Mach Number of 6.8 of Two Hypersonic Missile Configurations, One With Low-Aspect-Ratio Cruciform Fins and Trailing-Edge Flaps and One With a Flared Afterbody and All-Movable Controls

Description: Report presenting an investigation to determine the aerodynamic characteristics in pitch at a Mach number of 6.8 of hypersonic missile configurations with cruciform trailing-edge flaps and all-movable control surfaces. Testing indicated that all-movable controls on the flared-afterbody model should be capable of producing much larger values of trim lift and of normal acceleration than the trailing-edge-flap configuration. Some of the configurations tested include body alone, body with 5 degree … more

Aerodynamic Heating of Blunt Nose Shapes at Mach Numbers Up to 14

Description: From Introduction: "The importance of blunt noses as a means of reducing the heat transfer to high velocity missiles has recently received much publicity. The question of just what blunt shape is best is still moot, and it is the purpose of this paper to present and examine some recent experimental results which may throw some light on this problem."

Airborne Radioactivity Surveys in Geologic Exploration

Description: The following report describes the use of airborne radioactivity surveying and analytical techniques in geologic exploration by examples of the analysis or evaluation of airborne data related to specific geologic settings. The airborne radioactivity surveying program was begun in 1949 by the U.S. Geological Survey to assist in uranium exploration.

Analysis of effects of interceptor roll performance and maneuverability on success of collision-course attacks

Description: From Introduction: "In the present paper, calculations are presented to show the relative effects of wide variations in the roll performance and normal-accleration capability. Brief analyses are also included to show the effect on the success of attacks of other design factors such as speed and radar range."

Analytical and Experimental Investigation of Aerodynamic Forces and Moments on Low-Aspect-Ratio Wings Undergoing Flapping Oscillations

Description: "Aerodynamic forces and moments associated with flapping oscillations of finite wings at low speeds are considered. A comparison of theoretical and experimental results is made for a rectangular wing of aspect ratio 2. Calculated results are also given for three tapered wings of aspect ratio 3 with varying amounts of sweepback" (p. 1).

Bonding of DATB progress report

Description: A series of DATB (diaximotrinitrobenzine) pressings were made in an effort to find the most suitable binder. The requirements for this binder were as follows: Thermal stability (Must be as stable as DATB or not show any reaction with DATB at 200 degrees C); Density (Must press to 95% theoretical or higher); Compressive Strength (Must be strong enough to machine, and stronger if possible); Moldability (Must be adaptable to isostatic pressing conditions). After investigating various materials suc… more

Boron and zirconium from crucible refractories in a complex heat-resistant alloy

Description: In a laboratory study of the factors involved in the influence of induction vacuum melting on 55ni-20cr-15co-4mo-3ti-3al heat resistant alloy, it was found that the major factor was the type of ceramic used as the crucible. The study concluded that trace amounts of boron or zirconium derived from reaction of the melt with the crucible refactories improved creep-rupture properties at 1,600 degrees F. Boron was most effective and, in addition, markedly improved hot-workability.

Boundary-layer stability diagrams for electrically conducting fluids in the presence of a magnetic field

Description: From Summary: "The effectiveness of a magnetic field in stabilizing the laminar flow of an incompressible, electrically conducting fluid is studied. The neutral stability curves pertaining to a two-dimensional sinusoidal disturbance are presented for flow over a semi-infinite flat plate in the presence of either a coplanar or transverse magnetic field and for channel flow in the presence of a coplanar or transverse magnetic field and for channel flow in the presence of a coplanar magnetic field… more

A CHEMICAL ENGINEERING DEVELOPMENT PROGRAM-AN INVESTIGATION OF THE KINETIC MECHANISMS OF URANYL SALT ION EXCHANGE

Description: Recent literature concerning uranyl salt complex chemistry and ion exchange was reviewed in an effort to develop the present state of understanding of the equilibria and kinetic mechanisms involved. In the light of this, a development program is discussed which hopefully would lead to further enlightenment. Various kinetic mechanisms of sorption and elution are proposed and a comprehensive mathematical development is given for one such sorption mechanism. (auth)

Chemical Technology Division Unit Operations Monthly Progress Report, March 1958

Description: The alpha activity for scintillation area measurement was estimated to be 10/sup -6/ of that for the ( alpha ,n) methcd. The UF/sub 6/ recovery during Run FBR-16 was 67.3% of the theoretical recovery for the Fluorox reaction. Hydroclones were used for collection of thoria loop slurries with recoveries exceeding 99%. Flame calcination studies were continued with thoria dispersed in methanol by oxalic acid, using graphite and zirconia reflected burners and acetyleneoxygen flame. Equations for com… more

Chemical Technology Division, Unit Operations Section Monthly Progress Report for January 1958

Description: Absolute calibration of neutron yields from a polonium nitrate- fluorocarbon interface gave 8 neutrons/min, sq cm, mc/ml. In two Fluorox fluidized bed reactor runs UF/sub 6/ recoveries of 47 and 70% theoretical were attained. Washing and descaling operations for Loop P-1 have been completed. Preliminary studies of ThO/sub 2/ classification by hydroclones showed that particles as small as 0.5 micron could be classified. Continuous, self- sustaining operation of the Darex dissolver, stripper, and… more

COMPRESSIBILITY FACTORS AND FUGACITY COEFFICIENTS CALCULATED FROM THE BEATTIE-BRIDGEMAN EQUATION OF STATE FOR HYDROGEN, NITROGEN, OXYGEN, CARBON DIOXIDE, AMMONIA, METHANE, AND HELIUM

Description: Compressibility factors and fugacity coefficients for hydrogen, niftrogen, oxygen, carbon dioxide, ammonia, methane, and helium were calculated by use of the Beattie-Bridgeman equation of state. The results are tabulated for various pressures up to several hundred atmospheres, and temperatures up to several hundred degrees, at sufficiently close intervals to allow for easy interpolation. A comparison is made of the calculated compressibility factors with the experimental values over those range… more

Coolant water transient in K Reactor following line rupture

Description: This investigation is the second study of short period flow decay in the Hanford reactors. The first study was made on the D-Reactor. As in the analysis for D-Reactor quantitative analyses were made for ruptures that might result from sabotage. A visual inspection of the entire process water piping system was also made to check for any glaring deficiencies with respect to earthquake resistance. A brief discussion of the earthquake resistance of the system is also included in this report.
