The Sideband Technique In A Variable Frequency NMR Spectrometer

Description: The purpose of this Note is to point out the advantages of the sideband technique over the derivative method in wideline NMR spectroscopy. In the sideband technique the absorption spectrum is recorded directly and the modulation amplitude is no longer a determining factor in the resolution.

Double Meson Production In Proton-Deuteron Collisions. II

Description: In a previous publication we reported measurements of the momentum spectra of He<sup>3 and H<sup>3 nuclei produced in collisions of 740-MeV protons with deuterium. The He<sup>3 spectrum exhibited an anomaly in the form of a peak in the region corresponding to double pion production. For reactions resulting in a He<sup>3 the two pions (or particle) can be isotopic spin states 0 or 1; if a H<sup>3 nucleus results only 1 = 1 is allowed. We have since repeated the experiment with a new arrangement … more

Engineering Testing of the F-48 Columbium Alloy

Description: The F-48 columbium base alloy maintains useful mechanical properties for structural application up to 2600 degree F. Short-time tensile and creep rupture strengths have been determined for four F-48 plates, each from a different heat and with a different work history. Flow testing in a high-temperature, high-pressure air stream has been conducted to study oxidation behavior of the bare meatal. Auto-ignition is found to occur at a stream temperature of 2600 degree F. The phenomenon appears to be… more

Sheet Metal Can Furnace

Description: A need for a small vertical cylinder-type furnace arises frequently in the Chemistry Department at the Lawrence Radiation Laboratory (LRL). Adequate heat is the major requirement; close control or calibration is not usually necessary. A heating unit of this type can either be used for quickly concentrating solutions in centrifuge cones or, by the addition of a refractory pedestal--can be made into a crucible furnace for size 0 and 00 crucibles. Because much of the chemistry done at LRL is with … more

A Study of Sick Leave Practices of Texas Independent School Districts

Description: The problem of this study is threefold: (1) to determine whether the sick leave policies and practices differ significantly between school districts of different sizes; (2) to determine whether there is significant relationship between the number of days of sick leave allowed and the number of days taken by teachers; and (3) to determine whether significant trends in sick leave policies and practices can be detected between the years 1957 and 1960.

Factors Related to Change of Major by College Students

Description: The problem of this study is to discover what factors are associated with change of major in college students. Questions that need to be answered are (1) Is academic success or failure related to change of major? (2) Is mental ability associated with change of major? (3) Is change of interest related to change of major? (4) Are there reasons that are personal and peculiar to the individual that are associated with change of major? (5) Is inadequate occupational information related to change of … more

Remote Plastic Bag Passout Unit For High-Level Radiochemical Operations

Description: This system presents a method for making remote sealed-bag passouts from a multicurie-level chemistry processing enclosure. In addition, the polyethylene bags are changed remotely without exposing contaminated surfaces while always maintaining a low leak-rate seal. Our system employs an interchange box (the Passout Box) attached to the chemistry enclosure. Integrated with the box is a hydraulically operated jack that raises and lowers the bags, and a welder-cutter for sealing them. A single mas… more

The Influence of Rural and Urban Residence on Friendship Choices as Measured by a Sociometric Technique

Description: This study will be concerned with evaluating the degree of acceptance of rural students in an urban school. Because of increased interaction between the two groups on account of better modes of transportation, consolidation of schools, and a general trend in creating a more homogenous environment between the two groups the following null hypotheses have been formulated: 1. That there will be no significant difference in acceptance between the rural and urban pupils. 2. That there will be no sig… more

Development and Validation of a Sound Plan of Reorganization of the Public School Districts in Texas

Description: The problem of this study was to develop and validate a sound plan of reorganization of the public school districts in Texas. It may best be stated if considered as two subproblems: (l) to develop and validate criteria for reorganization of public school districts in the light of sound guiding principles; and (2) to devise a plan for school district reorganization In Texas in the light of the criteria established.

Literature Survey on World Isotope and Radiation Technology : First Interim Report Covering the Period from June 15, 1961 to August 14, 1961

Description: Abstract: "This is the first interim report of a literature survey investigating the uses and technology of radioscopes in the countries of the world, with particular emphasis necessarily placed on those more highly industrialized nations. Part I includes a general summary of the quantity and quality of radioisotope work being performed in these countries. Among the outstanding radioisotope applications with respect to quantity is the work of Japan in chemical research, that of USSR in metals r… more

A Pulsed Nanosecond Light Source

Description: A system for scintillations from nuclear events has been developed and is presently in use at the Lawrence Radiation Laboratory. This paper primarily describes the pulsed light source used to simulate nuclear events; it also describes the necessary nanosecond pulse techniques to measure the light source parameters and to operate large numbers of lamps. Considerations concerning distribution networks are shown. Use of the light source as a spark gap trigger is also discussed.
