This paper will attempt to investigate and further define the two ideas of rest in Hebrews 3:7-4:13

Legislative Oversight in the North Dakota State Legislature

The purpose of this study is to look at the extent of legislative oversight in the North Dakota State Legislature. The State\u27s legislators meet only once every two years for about four months and the rest of the time they are fulltime private citizens and parttime legislators. Oversight of North Dakota\u27s Executive Branch must be done by legislators who are being pulled in several directions by job, family and constituents. Oversight does not rate high on the priority list in the legislative interim. In order to get an idea of what types of oversight are available to the State\u27s legislators, this study compares congressional oversight to State oversight techniques. The similarities are interesting. While there is quite a bit written about congressional oversight, little study has been done on state oversight. In order to get a handle on oversight methods available to North Dakota\u27s legislators and the methods actually used by them a series of interviews were conducted. Chester Nelson, the Legislative Council\u27s fiscal analyst and auditor was interviewed concerning fiscal oversight available to the State\u27s legislators. John Olsrud, Director of the Legislative Council staff, talked about the role of the council staff in assisting legislators in oversight. And finally, fourteen of the State\u27s legislators were interviewed to determine how they feel about oversight

Classification of tropical precipitation regimes: a comparative analysis of disdrometer, profiler, and multi-parameter radar measurements

Fall 2000.Includes bibliographical references.The key objective of the Tropical Rainfall Measuring Mission is to improve estimates of the diabatic heating in tropical precipitation. These improvements depend on the separation of the convective and stratiform components of a precipitating system since each type of precipitation exhibits a different latent heating profile. The objectives of this study were to develop a classification algorithm using multiparameter radar data and apply it and several existing classification algorithms to the TRMM-LBA data set. We have developed a precipitation classification algorithm that identifies convective precipitation within the storm complex using multiparameter radar data. This identification depends on the intensity and trend of the estimated precipitation rate. The existing algorithms use disdrometer data, Doppler profiler systems, and radar reflectivity to classify precipitation. Comparisons between each algorithm were made, which provided the opportunity to evaluate the performance of each algorithm over a variety of precipitation events. The disdrometer-based algorithm failed to classify 14% of the data, leading to poor agreement with the remaining algorithms. The profiler-based, reflectivity-based, and multiparameter algorithms agreed well; of 430 minutes of precipitation, they classified 36%, 41%, and 40% as convective respectively. The total convective area produced by the reflectivity-based algorithms and the multiparameter algorithm agreed reasonably well. Qualitative inspection of the classification results by the reflectivity­ based and multiparameter algorithm showed each algorithm's ability to identify the cellular structure within the precipitating events as convective.Sponsored by the National Science Foundation and National Aeronautics & Space Administration under grants ATM-9726464 and NAG 5-4754

Rotationally actuated prosthetic helping hand

A prosthetic device has been developed for below-the-elbow amputees. The device consists of a cuff, a stem, a housing, two hook-like fingers, an elastic band for holding the fingers together, and a brace. The fingers are pivotally mounted on a housing that is secured to the amputee's upper arm with the brace. The stem, which also contains a cam, is rotationally mounted within the housing and is secured to the cuff, which fits over the amputee's stump. By rotating the cammed stem between the fingers with the lower arm, the amputee can open and close the fingers

Detailed analysis of low energy plasma data under the Voyager Uranus data analysis program

Research effort included the PLS data analysis program where modifications to the data fitting procedure and elimination of possible noise and electron contamination were made. The analysis code corrections were used in checking the Neptune data gathered during the Voyager 2 encounter and for analyzing selected plasma spectra from the warm Io torus. A major task accomplished was the summary of Uranus-related research in the U.S. National Report to the International Union of Geodesy and Geophysics for the 1987 - 1990 quadrennium. A limited amount of work was accomplished on assessing the Pedersen conductivity of the ionosphere and comparing it with inferred values from shielding by the Uranian ring current. Under this grant there has been a great deal of effort expended on identifying and classifying plasma waves and oscillations in the magnetosheath and solar wind downstream from Uranus. Large amplitude oscillations in plasma parameters are found in the magnetosheath, with density changes of up to a factor of ten occurring on times scales of minutes. New algorithms developed for analyzing the inbound bow shock crossing of Neptune will probably be applied to a more detailed analysis of the Uranus shock in the near future

Modification of Surface Energy via Direct Laser Ablative Surface Patterning

Surface energy of a substrate is changed without the need for any template, mask, or additional coating medium applied to the substrate. At least one beam of energy directly ablates a substrate surface to form a predefined topographical pattern at the surface. Each beam of energy has a width of approximately 25 micrometers and an energy of approximately 1-500 microJoules. Features in the topographical pattern have a width of approximately 1-500 micrometers and a height of approximately 1.4-100 micrometers

The Distance to the Heliospheric VLF Emission Region

Two major episodes of heliospheric VLF emissions near 3 kHz have been observed by the Voyager spacecraft in 1983-1984 and 1992-1993. This higher-frequency component is apparently triggered by solar wind transients with sufficiently large spatial extents and energies to continue to propagate as shocks in the heliosheath. Entrainment of previously unshocked material and changed flow conditions in the heliosheath both tend to slow the shock propagation. The shock evolution is not self-similar. Rather, it is intermediate to two blast-wave similarity solutions in the moving solar wind frame. In one solution the shock moves as time to the 2/3 power and in the other as time to the 4/5 power. Using these models, the shock/Forbush decrease observed at Voyager 2 in September, 1991 and the turn-on of the 1992 emission is consistent with an emission region distance of approx. 130 AU (assuming no additional slowing of the shock in the heliosheath). If the termination shock was at approx. 70 AU when the transient shock collided with it, the true distance to the source region was probably closer to approx. 115 AU

REFINING OF MgX AND OTHER URANIUM-BEARING MATERIALS

A study of the effect of feed and ether acidity on the extraction of vanadium and molybdenum from process solutions by ethyl ether is described. Results of batch and continuous extraction tests on the extraction of uranium from process slurries by tributyl phosphate-Gulfspray naphtha are presented, including studies of the effects of feed and scrub acidities on the concurrent extraction of molybdenum. The effect of temperature on the stripping of uranium from tributyl phosphate was studied briefly. Results from fractional precipitation of MgX from dilute sulfuric acid solutions indicate that, in the presence of sufficient iron, phosphate is precipitated as ferric phosphate, and not as uranyl pho sphate.
