This paper explores selected questions involving the busing of elementary and secondary school students for desegregation. On each of the selected questions a general analysis of the issue involved is presented, followed by two subsections entitled A Critic's Position and An Advocate's Position. In these subsections, an attempt is made to show how a critic of busing for desegregation and an advocate of such busing might fashion arguments on this issue in opposition to, or in support of, busing.

A data transmission system is disclosed which includes a transmission medium which has a certain propagation delay time over its length. A number of data stations are successively coupled to the transmission medium for communicating with one another. Each of the data stations includes a transmitter for originating signals, each signal beginning with a carrier of a duration which is at least the propagation delay time of the transmission medium. Each data station also includes a receiver which receives other signals from other data stations and inhibits operation of the transmitter at the same data station when a carrier of another signal is received.

The disclosure relates to a multipolar probe using radiofrequency energy to reshape the cornea of an eye. The surface of the cornea is flushed continuously with a conductive coolant during operation.

The CaO-FeS/sub 2/ reaction was studied as a function of temperature, reaction time, Ca/S mole ratio and particle size. All reactions were carried out under a nitrogen environment. The reactions were followed principally in terms of weight loss and SO/sub 2/ emissions. The decomposition of the pyrite produces S/sub 2/ which reacts with CaO to produce SO/sub 2/ and CaS. The extent of the reaction appears to increase monotonically between 555 and 970/sup 0/C.

Five-gallon samples of naphtha, middle distillate, and heavy distillate were obtained. The middle and heavy distillate fractions were distilled into eleven 50 C-range cuts with boiling points ranging from <150/sup 0/C to >450/sup 0/C. Analyses were completed on all the samples to be used in the Task 2 pyrolysis study. Initial pyrolysis experiments using the drop-tube furnace procedure are not as satisfactory as desired. A new approach is being devised which will vaporize the sample and allow for a gas phase pyrolysis.

Tests are continuing on the shatter-resistant weathercase models and small samples. Two epoxy weathercase material samples are still undergoing accelerated tensile creep tests. Progress is reported on the design of the full scale prototype termination.

Methods for comparative evaluations of the Office of Transportation programs designed to help achieve significant reductions in the consumption of petroleum by different forms of transportation while maintaining public, commercial, and industrial mobility are described. Assessments of the programs in terms of petroleum savings, incremental costs to consumers of the technologies and activities, probability of technical and market success, and external impacts due to environmental, economic, and social factors are inputs to the evaluation methodologies presented. The methods described for evaluating the programs on a comparative basis are three ranking functions and a policy matrix listing important attributes of the programs and the technologies and activities with which they are concerned and include the traditional net present value measure which computes the present worth of petroleum savings less the present worth of costs. This is modified by dividing by the present value of DOE funding to obtain a net present value per program dollar, which is the second ranking function. The third ranking function is broader in that it takes external impacts into account and is known as the comprehensive ranking function. Procedures are described for making computations of the ranking functions and the attributes that require computation. Computations are …

Objective is to improve current understanding of sodium voiding behavior under postulated LMFBR accident conditions. Multi-dimensional computer models are being developed under low flow and low power conditions. The following computer codes are being developed and assessed: NATOF-2D, THERMIT-S-6E, and THERMIT-S-4E. The effect of virtual mass on the characteristics and numerical stability in two-phase flows was studied. (DLC)

The purpose of the Oak Ridge Flywheel Evaluation Laboratory Annual Report is to present work performed for and funded by the Mechanical Energy Storage Technology Project at Lawrence Livermore National Laboratory (LLNL). In addition to the management sections (schedules, budgets, and facility accomplishments), summaries are given for the ultimate speed evaluations of one flywheel built by Union Carbide Corporation, Nuclear Division (UCC-ND); four flywheels constructed under subcontracts from Sandia National Laboratory, Albuquerque; one fabricated by LLNL; and one manufactured by General Electric Company. Also included are the test results from two momentum transfer tests of the UCC-ND-designed flywheel. Prototype crash rings were used in a number of these tests, and a discussion of their performance is included.
