Mechanical Behavior of Crystalline Solids: Proceedings of a Symposium, April 28-29, 1962

Description: From Introduction: "These first three chapters from a background of introduction and general ideas about dislocations. The next two chapters are concerned specifically with properties of ceramic materials, with emphasis on single crystals."

Trace Characterization: Chemical and Physical

Description: From Introduction: "This symposium focuses attention on the growing awareness of the necessity for developing and using better methods for characterizing solids. Many of the most interesting properties of solids depend directly upon these small concentrations of impurities and defects, and the illustration of this is a principal theme of this paper."

Transient Temperatures in Infinite Plates, Infinite Cylinders, and Spheres During Convective Cooling from Initially Parabolic Temperature Profiles

Description: Report presenting "the evaluations of the series which represent the solutions to the Fourier equation in rectangular, cylindrical and spherical coordinates for the case in which the initial temperature field is that owing to a spatially uniform heat source" (p. 1).

Theory of Reversible and Nonreversible Cracks in Solids

Description: The Griffith crack theory is reviewed and certain shortcomings of this theory are discussed. A new description for the shape of a crack is given which takes into account the atomic structure of material. Through consideration of the total energy of the system and the shape of the crack, expressions for crack behavior are derived which are considered to remedy the defects of the Griffith theory.

Statistical Summary of Daily Values Data and Trend Analysis of Dissolved-Solids Data at National Stream Quality Accounting Network (NASQAN) Stations

Description: From abstract: A statistical summary of the available continuous and once-daily discharge, specific-conductance, dissolved oxygen, temperature, and pH data collected at NASQAN stations during the 1973-81 water years and documentation of the period of record on which the statistical calculations were based are presented.

Description: A discussion of the fundamental aspects of vaporization is presented along with a discussion of evaporation within the theories of solids and gases. Suggestions are offered as to where assumptions might be introduced to describe the phenomenon more completely, and tenative definitions concerning factors which can give rise to vaporization coefficients are given. An effort is made to unify these concepts within the phenomenological framework of irreversible thermodynamics. (J.R.D.)

Description: A simplified model for solids deposition in the pot calcination of waste was analyzed, and numerical calculations were made. In long calcination pots of 10 to 12 in. diameter, calcination times should not exceed 24 hours and might be as low as three hours if the pot is kept full. If the pots are fed at a constant rate, the cake might form with a steady state V'' when viewed in vertical section which would progress from bottom to top. Cake deposition rates appear to be independent of pot radius. Several advantages to using larger diameter pots are discussed. (auth)

Reservoir Development Impacts on Surface-Water Quantity and Quality in the Yampa River Basin, Colorado and Wyoming

Description: From introduction: This report describes the results of an investigation in which three computer models were used to evaluate different levels of the proposed reservoir development. One model simulated streamflow conditions with alternative multireservoir configurations; a second model simulated the dissolved-solids concentrations at various locations in the basin; and a third model used streamflows and dissolved solids concentrations to simulate the water-quality conditions within certain proposed reservoirs. This study was designed to demonstrate the application of computer-modeling techniques in evaluating impacts of proposed reservoirs.

Versatile assembly of p-carboxylatocalix[4]arene-O-alkyl ethers

Description: Crystallisation of lower-rim tetra-O-alkylated p-carboxylatocalix[4]arenes from pyridine results in the formation of both bi-layer and pillar type supramolecular motifs. Full alkylation at the calixarene lower rim has significant influence over the supramolecular self-assembly motif, including preclusion of pyridine guest molecules from the calixarene cavity in the solid state.

Description: BS>A theoretical model was developed for the purpose of predicting the motion of objects translated by winds associated with "classical" blast waves produced by explosions. Among the factors omitted from the model for the sake of simplicity were gravity and the friction that may occur between the displaced object and the surface upon which it iritially rested. Numerical solutions were obtained (up to the time when maximum missile velocity occurs) in terms of dimensionless quantities to facilitate application to specific blast situations. The results were computed within arbitrarily chosen limits for blast waves with shock strengths from 0.068 to 1.7 atm (1 to 25 psi at sea level) for displaced objects with aerodynamic characteristics ranging from those of a human being to those of 10-mg stones and for weapon yields at least as small as 1 kt or as large- as 20 Mt.

Fuel Elements Conference Held at Gatlinburg, Tennessee, May 14-16, 1958

Description: The fuel element conference provided a favorable medium for presentation and discussion of recent developments in the field of solid fuel elements. The conference was designed to replace the more general Metallurgy Information Meetings held annually in the past. The scope of the meeting embraced the design fabrication, performance, and material problems of fuel elements. (W.D.M)
