QIKMIX: a quick-turnaround computer program for computing opacities of mixtures
QIKMIX is a quick-turnaround computer code developed to compute the radiative Rosseland mean opacity of specified mixtures at specified temperature and density points. The QIKLIB data base, which QIKMIX uses, has been derived from the OPLIB library. For most mixtures, QIKMIX can compute opacities over a temperature range of 50 to 25,000 eV in less than 1 min of CDC 7600 computer time. The purpose of this report is to discuss the QIKLIB data base and the operation of the QIKMIX code.

Topics in bound-state dynamical processes: semiclassical eigenvalues, reactive scattering kernels and gas-surface scattering models
The difficulty of applying the WKB approximation to problems involving arbitrary potentials has been confronted. Recent work has produced a convenient expression for the potential correction term. However, this approach does not yield a unique correction term and hence cannot be used to construct the proper modification. An attempt is made to overcome the uniqueness difficulties by imposing a criterion which permits identification of the correct modification. Sections of this work are: semiclassical eigenvalues for potentials defined on a finite interval; reactive scattering exchange kernels; a unified model for elastic and inelastic scattering from a solid surface; and selective absorption on a solid surface.

Coal feeder survey for Illinois coal gasification group. [Lockhopper, Fuller Kinyon screw, Foster Miller pocket feeder]
An evaluation of three coal feeder concepts (lockhopper, Fuller Kinyon screw and Foster Miller pocket feeder) for use in the ICGG first stage gasifier was made. For the sake of consistency, all feed concepts were evaluated on the same basis, that is, feeding a nominal 100 Tons per hour (TPH) against a back pressure of 50 psig. Also, all feed systems were assumed to have similar atmospheric storage hoppers and final injection systems. Accordingly, no further consideration of these support systems was made. This survey was accomplished by reviewing the literature, interviewing vendors, contacting applicable facilities and performing necessary original analysis. The emphasis of the survey was on the test and industrial experience of each system. The results of this survey which are summarized on Table I show that the lockhopper system still should be considered as the baseline system because it is a proven system with extensive operating experience. On the other hand, if definitive tests can prove conclusively that the Fuller Kinyon screw pump will deliver coal against 50 psig back pressure with acceptable efficiencies and coal particle attrition characteristics, it would be the preferred system because it is the lowest cost and easiest to maintain. The Foster …

The Effect of Reading Preference on Reading Comprehension of Low Socioeconomic High School Students
The problem of this study was to examine the effect of reading preference on reading comprehension of low socioeconomic high school students. Subjects were 61 participants in the Upward Bound program at a major southwestern university; they represented urban high schools with high proportions of students of low socioeconomic status. Subjects completed cloze procedure reading passages in four categories: high preference independent level, high preference frustration level, non-expressed preference independent level, and non-expressed preference frustration level. From the results gathered, it was recommended (1) that reading ability assessments include measuring performance with high preference materials, (2) that instructional personnel ascertain and utilize student preferences as foundations for reading instruction, (3) that reading material not be withheld from students on the basis of difficulty, (4) that high preference reading materials be used in reading instruction by secondary reading and content area teachers, and (5) that school patrons be made aware of the value of free preference reading in reading skill development.

Calculations Pertaining to the Design of a Prebuncher for a 150-MeV Electron Linear Accelerator. [Part] 2. Radial Motion
In the previous paper, calculated results based on a one-dimensional ballistic model were presented to indicate the extent to which a current pulse of 150-keV electrons containing 1 ..mu..C of charge and having a duration of 15 nsec (FWHM) could be bunched by a combination of accelerating and decelerating voltage gaps followed by a drift space. A very approximate perturbation model is used here to determine the extent to which the prebuncher performance determined previously is modified by radial electron motion. It is found that if a longitudinal magnetic field of 1 kG is applied in the region containing the voltage gaps and if a sufficiently strong longitudinal magnetic field (approx. 3 kG) is applied in the drift space the prebuncher performance determined here is essentially the same as that shown in the previous paper.

Nuclear waste disposal in subseabed geologic formatons: the Seabed Disposal Program
The goal of the Seabed Disposal Program is to assess the technical and environmental feasibility of using geologic formations under the sea floor for the disposal of processed high-level radioactive wastes or repackaged spent reactor fuel. Studies are focused on the abyssal hill regions of the sea floors in the middle of tectonic plates and under massive surface current gyres. The red-clay sediments here are from 50 to 100 meters thick, are continuously depositional (without periods of erosion), and have been geologically and climatologically stable for millions of years. Mineral deposits and biological activity are minimal, and bottom currents are weak and variable. Five years of research have revealed no technological reason why nuclear waste disposal in these areas would be impractical. However, scientific assessment is not complete. Also, legal political, and sociological factors may well become the governing elements in such use of international waters. These factors are being examined as part of the work of the Seabed Working Group, an international adjunct of the Seabed Program, with members from France, England, Japan, Canada, and the United States.

SHADE: a computer model for evaluating the optical performance of two-axis tracking parabolic concentrators
A computer model SHADE (Selection of Heliostat Arrangement for Distributed Engines) has been developed at the Pacific Northwest Laboratory to aid in determining the optical performance of two-axis tracking parabolic concentrators. The shading of individual mirror assemblies in a field of parabolic dishes determines the optimal field arrangement and the most efficient method of plant operation. SHADE provides a simple and inexpensive analytical tool for examining certain design aspects of solar thermal power systems using a network of point-focusing parabolic concentrators.

International development assistance for renewable technologies: current programs and institutional requirements
Within the last several years, foreign-assistance donor agencies have begun to provide significant aid for the search for renewable energy sources for developing nations. This paper reports preliminary results from a survey of development--assistance projects in renewable energy sources, indicating which areas are extensions of traditional assistance areas and which are new areas of involvement. The last two portions of the paper indicate certain shortcomings in the current effort, and linkages that must be emphasized in order to incease the effectiveness of the range of donor activities.

A Study of Texas Teachers' Fulfillment of the Educators' Code of Ethics
The purposes of this study were to determine the perceptions selected school personnel had of public school teachers' fulfillment of the code of ethics for Texas educators, if these perceptions differed significantly, and if the code had any significant impact on teachers' behavior. The subjects consisted of board members, superintendents, principals and teachers within seven urban, fourteen suburban, and fifty rural Texas school districts. Subjects’ responses to an instrument derived from the Code of Ethics for Texas Educators provided the data for testing. The findings of this study included the following: 1. Board members perceived teachers as fulfilling the code to be slightly higher than did teachers and principals and significantly higher than did superintendents. 2. Superintendents perceived teachers as fulfilling the code to a lower degree than did the other subjects surveyed. 3. Subjects selected within urban and suburban school districts are in perceptual agreement concerning teachers' fulfillment of the code. 4. Rural board members perceived teachers as fulfilling the code to a slightly higher degree than did rural superintendents. 5. Urban teachers perceived teachers as fulfilling the code to a significantly higher degree than did suburban teachers. 6. The code of ethics was perceived as having low to …

Metabolism and biological effects of alpha-emitting radionuclides
The emphasis of much of the current and planned research on the toxicity of alpha-emitting radionuclides is directed toward the complexities of actual and potential conditions of occupational environmental exposures of human beings. These, as well as the more limited studies on mechanisms of biological transport and effects, should increase our ability to predict health risks more accurately and to deal more confidently with human exposures, if and when they occur.
