The Forum Of Conscience: Applying Standards Under The Free Exercise Clause, Paul Marcus
The Forum Of Conscience: Applying Standards Under The Free Exercise Clause, Paul Marcus
Faculty Publications
The 1973 Supreme Court decision in Wisconsin v. Yoder reenforced and amplified the Court's earlier holding in Sherbert v. Verner that the free exercise clause of the first amendment requires the state to render substantial deference to religiously motivated behavior in the application of its laws and regulatory schemes. In this article, Mr. Marcus traces the evolving standards of free exercise doctrine and observes that the "balancing test" which has resulted from that evolution requires still further refinement to give religious freedom its full constitutional due. The author then illustrates how the new standards of free exercise might be applied …

Wigner And Racah Coefficients For Su3, J. P. Draayer, Yoshimi Akiyama
Faculty Publications
A general yet simple and hence practical algorithm for calculating SU 3 ⊃ SU2 × U1 Wigner coefficients is formulated. The resolution of the outer multiplicity follows the prescription given by Biedenharn and Louck. It is shown that SU3 Racah coefficients can be obtained as a solution to a set of simultaneous equations with unknown coefficients given as a by-product of the initial steps in the SU3 ⊃ SU2 × U1 Wigner coefficient construction algorithm. A general expression for evaluating SU3 ⊃ R3 Wigner coefficients as a sum over a simple subset of the corresponding SU3 ⊃ SU2 × U1 …

Electrochemical Reduction Of Molybdenum(Vi) Compounds In Molten Lithium Chloride-Potassium Chloride Eutectic, Branko N. Popov, H. A. Laitinen
Electrochemical Reduction Of Molybdenum(Vi) Compounds In Molten Lithium Chloride-Potassium Chloride Eutectic, Branko N. Popov, H. A. Laitinen
Faculty Publications
Molybdenum (VI) oxide reacts with molten LiCl-KCl eutectic at 450° to form MoO2CI2, which probably is present as an anion MoO2Cl4=, and pyromolybdate, Mo2O7=. Both of these species are electrochemically reduced to MoO2, which can be reoxidized to MoO2Cl2 by current reversal. A second reduction step, observed whether MoO3 or Mo2O72− is added to the melt, can be attributed to the reduction of MoO4−−, formed as a secondary reaction product in the first …

For the past several years; much emphasis has been placed on open enrollment plans involving bussing that enable black and white students to attend schools together. The Laboratory School of the University of Northern Iowa in Cedar Falls has been involved in such a program since 1968. As the project developed; the potential for very serious problems relating to racial tension and student frustration became evident. To approach these problems and to promote more openness and understanding between students from different communities and differing cultural backgrounds; cross-cultural group counseling sessions were developed. The groups during the past two years have …

Utterances of two adults males were analyzed and synthesized by a fast Fourier Transforms method. Each of the two voices was synthesized in each of the twenty‐seven combinations of three levels each of rate, mean FØ, and variance of FØ (a total of fifty‐four “voices” generated from two). The effects of the rate, mean FØ, and variance of FØ manipulations, the interactive effects of rate and variance of FØ, and the effects due to speaker were all statistically significant predictors of personality ratings given the voices. They accounted for 86%, 4%, 3%, 2%, and I% of the …

X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve Ii. Sodium, Keith H. Brown, J. Dean Barnett
Faculty Publications
Coherent x-ray diffraction patterns for liquid Na have been extracted from measured patterns at 0.5, 7.5, 17, and 43 kbar along the melting curve. The experimentally determined liquid structure factor and resulting radial distribution function are given at each pressure. The position of the principal x-ray intensity peak is reproducible to within 0.5% and shows shifts of the order of 12%. The resulting nearest neighbor distance in the radial distribution function also shifts 12% but is reproducible only to approximately 2%. The distribution functions obtained at points along the melting curve suggest a simple dimensional compression or scaling; however, a …

X-Ray Diffraction Studies On Liquids At Very High Pressures Along The Melting Curve. I. Methods And Techniques, Keith H. Brown, J. Dean Barnett
Faculty Publications
A technique using the tetrahedral anvil high-pressure x-ray system has been developed to extract coherent x-ray intensity patterns of liquids near melting from measured scattering curves in the presence of high-background counts. Radial distribution functions for liquids along the melting curve to pressures of at least 50 kbar can be obtained. At each pressure scattering curves are recorded for the liquid and solid on opposite sides of the melting curve and a subtraction is made to eliminate background and incoherent scattering. Theoretical estimates of the thermal diffuse scattering from the solid are added to the appropriately corrected difference patterns to …

The delayed-proton spectrum following the β decay of 9C (t1/2=126.5±1.0 msec) was found to consist primarily of a continuum extending from 13 to 1.5 MeV, the latter being the lowest energy observed. In addition to the previously observed peaks at 9.28 and 12.30 MeV (C.M.), possible peaks between 3 and 7 MeV have been tentatively identified.

Wells And Streams: Relationship At Law, Peter N. Davis
Faculty Publications
Groundwater constitutes one of the major sources of water for municipalities, irrigators, and rural dwellers. Conflicts between groundwater users are bound to arise from time to time, as is evidenced by a recent Missouri case, Higday v. Nickolaus, discussed elsewhere in this issue.' Such conflicts may increase in frequency in the future as the demand for groundwater increases. Although a majority of cases will involve allocation of groundwater between users of that class of water, many groundwater diversion cases will involve adverse effects on the flow of water in streams. It is –to the latter situation that this article is …
