Critical Pressure Ratio for a Nozzle with Two-Phase Fog Flow

Description: In many cases of analysis of two-phase flow in systems, considerable computation or program time could be saved if the critical pressures ratio were known. If a reservoir or plenum pressure is fixed, the usual computational procedure involves the assumption of several critical pressures and the generation of several momentum terms to find the applicable critical pressure ratio and thereby the critical flow. The formulation of an equation of state make it possible to compute critical pressure ra… more

A Critical Survey of Neutron Cross Sections

Description: From introductory paragraphs: "The central problems in neutron research are the understanding of nuclear structure and the study of the properties of nuclear particles, particularly the properties of the neutron. The most fruitful attack on these problems is the determination of the probability of interactions between neutrons and nuclei, i.e., the measurement of neutron cross sections. Ideally, this involves the study of all possible types of neutron interaction with all available nuclei at al… more

Criticality-Accident Dosimetry Studies

Description: Experiments were carried out to (1) explore possibilities for developing a less expensive device than the Hurst threshold detector unit (TDU) for monitoring possible accidental critical reactions in uranium-processing facilities, (2) to study the precision and accuracy of the TDU, and (3) to evaluate the ORNL film badge in mixed neutron-gama radiation fields.

"Crud" Scrubbing with a Purex-Type Zebra Cartridge

Description: Entrained solids have in the past been one of the major factors limiting solvent extraction fission product decontamination. These solids are known to be surface active, to absorb fission products, and to form interfacial films or "cruds". A major step in eliminating these cruds was taken when the Purex columns were modified to operate with the interfaces at the waste ends of the columns rather than the product ends. This type of operation tended to flush the solids out with the waste rather th… more

Crude Oil: Qualitative and Quantitative Aspects: The Petroleum World

Description: Report issued by the U.S. Bureau of Mines discussing qualitative and quantitative aspects of the petroleum industry. As stated in the introduction, "the purpose of this report is to present authoritative qualitative data from many sources in such a manner as to form an authentic and understandable picture of crude oil as we know it today. The qualitative facts will be augmented by some semi-quantitative data to provide a somewhat broader perspective" (p. 2). This report includes tables, and ill… more

A Cryostat for Temperature Control in the Range from Ambient to - 150 degrees C

Description: This note describes a simple cryostatic device, which, by utilizing the latent heat of vaporization of liquid nitrogen, enables accurate control of temperature between ambient and - 150 degrees C. The advantages of this cryostat over other models known are simplicity of design and operation, ability to operate accurately from ambient to - 150 degrees C, economy, and large working space.

Crystal Structure of a Sodium Cobalt Molybdate

Description: The cobalt and molybdenum positions had been derived from a three-dimensional Patterson function based on complete data out to λ-1 sin θMo≈ 1. From the separation of the separation of the Mo atoms it was thought that the structure contained free, unlinked MoO4 -2 ions, and this, together with the observed density and analyses for Co and Mo, suggested that the composition was probably Co2(MoO4)3. The paucity of structural information on complex oxide systems and the interesting properties, both … more

Crystal Structure Of B 'Cu0.75Al0.25

Description: The problem of crystal structure of the martensitic B1 phase of the eutectic alloy in the Cu-Al system still requires a more accurate clarification (Hun ger and Dienst 1960, Tarora 1949). Martensitic phases in general are formed through small thrust (shear) deformations of the original lattice. On this basis the results of Hunger and Dienst (1960) are doubtful, since the lattice constants found by them have required a considerable reclassification. From the known lattice constants of the B1 pha… more

The Crystal Structure of Bis(Meta-Chlorobenzoyl) Methane

Description: Technical report. From Abstract : "The crystal structure of bis(meta-chlorobenzoyl) methane has been determined by three dimensional anisotropic least squares refinement of scintillation counter data. The molecule was found to be nearly planar with a maximum deviation from the least squares molecular plane of 0.068Å and an average deviation of 0.023Å. Fourier transform techniques to locate phenyl rings provided the key to the structure determination. The intramolecular bond distances and therma… more

Crystal Structure of Bis (Meta-Chlorobenzoyl) Methane

Description: Technical report. From Abstract : "The determination of the crystal structure of bis(meta-chlorobenzoyl)-methane was undertaken by x-ray methods in an effort to clarify the ambiguous position of the hydrogen atom on the enolic form of β - diketones and hence in intramolecular hydrogen bonds."

The Crystal Structure of Bismuth Subchloride

Description: Technical report. From Abstract : "The stoichiometric formula of the lower chloride in the BiCl3-Bi system has been established as Bi12Cl14 (BiCl1.167) through a dingle crystal, X-ray determination of its structure. ... Previous studies of the Bi-Cl3-Bi system are re-examined in the light of the structural results."

The Crystal Structure Of Cobalt Sulfate Hexahydrate

Description: Calorimetric measurements by Rao and Giauque (1960) showed some unaccountable residual entropy in crystals of [formula] at low temperatures. We have investigated the crystal structure in search of an explanation of the disorder. The resulting structure offers no possibility of disordered rings of hydrogen bonds such as were found in [formula], nor do we find any other explanation of the entropy discrepancy.

The Crystal Structure of LiCuCl3-2H2O*

Description: This report undertakes research to study LiCuCl3-2H2O is from a structural standpoint, revealing the oxygen positions. The study uses the Levy-Bussing anisotropic temperature factor treatment and least squares program to determine a discrepancy factor for the visually determined intensities. The structure of the molecule is also found to have interesting magnetic properties which has inspired a new study at Brookhaven.

Crystal Structure Of Propionic Acid

Description: The crystal structures of the normal fatty acids of low molecular weight have been rather neglected until recently. Formic acid and acetic acid occur in the solid as hydrogen-bonded linear polymers, while several acids with eleven or more carbon atoms per molecule exist in the solid as dimers. The melting points of these acids, when plotted against number of carbon atoms, fall on two rather similar curves for even and odd numbers of carbon atoms, respectively, each with a minimum near five carb… more

Crystalline Field Splittings in Holmium and Dysprosium Ethylsulfates

Description: From report : "It has become apparent that pragmatic resonance data alone are insufficient to correctly evaluate crystal field parameters for rare-earth ethylsulfates, and that heat capacity data above 20°K are a useful aid in determining whether low lying levels obtained by absorption spectroscopy have been correctly identified."

Crystallography of Some of the Transition Element Beryllides

Description: A crystallographic study of the transition element beryllides was undertaken in support of phase diagram work. These beryllides are very high melting, and the use of ordinary methods make it difficult to determine stoichiometry. We have succeeded in establishing the compositions and complete crystal structure description of all of the room temperature stable or metastable compounds of the beryllides of niobium, tantalum, titanium zirconium, hafnium, vanadium, chromium and molybdenum. Since some… more
