Letter from W. E. Potter to Representative Burdick Regarding Garrison Dam, US Army Engineers, and Water Systems for Van Hook and Sanish, North Dakota, April 6, 1950

This letter, dated April 6, 1950, from Colonel W. E. Potter of the United States (US) Army Corps of Engineers to US Representative Usher Burdick concerns the authorization of the US Army Engineers to assist in the construction of new water and sewage systems for Van Hook and Sanish, North Dakota. In it, Potter reference Burdick\u27s February 16 letter on the topic, stating that Sanish and Van Hook have no publicly owned water and sewage systems, instead obtaining water from private wells and cisterns. He goes on to discuss the relocation of Sanish and details the proposed North, South, and East sites, giving estimates for water systems for each site, and ultimately suggesting that combining the two towns may be the best option, as this would enlarge the community and make use of a modern sewage system. He concludes by stating that the US Army Engineers are not authorized to provide public water and sewage which have no existing counterparts in present towns, and that instead the owners of the private water systems would be compensated by the acquisition of real properties.https://commons.und.edu/burdick-papers/1446/thumbnail.jp

Letter from W. E. Potter to Representative Burdick Regarding the Budget for Projects in the Missouri Basin, January 21, 1955

This letter, dated October 1, 1945, from United States Brigadier General W. E. Potter of the United States (US) Army Engineers to US Representative Usher L. Burdick informs Burdick that Potter has prepared an analysis of the funds recommended in the President’s budget for the United States Corp of Engineers, of which $20,000,000.00 is the recommended appropriation for the Garrison Dam. In an underlined section, Potter writes that Construction and land acquisition in the Williston area are not included in the work programmed for fiscal year 1956. The letter goes on to outline specific dam projects in South Dakota, Nebraska, and Wyoming and their proposed budgetary expenditures.https://commons.und.edu/burdick-papers/1555/thumbnail.jp

Electrochemical sintering process for producing electrodes from cadmium felt and a nickel or silver grid

Electrochemical sintering process produces cadmium felt electrodes. Two pieces of cadmium felt are sandwiched around a nickel screen or silver expanded metal grid, held together by mold compression, and electrochemically sinitered by being put through several charge and discharge cycles at low current density

Providing Web Surfers With Useful Information About Plants via PlantSage

The World Wide Web has opened substantial avenues for research into accessing and disseminating vast amounts of information to millions of users all over the world. As a result, it is now very common for people at all levels of computer literacy to “surf the net” in search of information. However, finding useful information can be a laborious and tedious task, especially for those unfamiliar with the Web. Our goal is to improve both the usefulness and the ease of web-based information gathering. In particular, we place a special emphasis on horticulture-based information. In the PlantSage project, we provide access to three different sources of information: a local database, a search on selected “partner” sites, and a search on the entire web that not only returns names and URLs of relevant sites but also collates and uniformly formats potentially useful information. This paper will describe each of these processes and our plans for enhancing them

The role of freestream turbulence scale in subsonic flow separation

The clarification of the role of freestream turbulence scale in determining the location of boundary layer separation is discussed. Modifications to the test facility were completed. Wind tunnel flow characteristics, including turbulence parameters, were determined with two turbulence generating grids, as well as no grid. These results are summarized. Initial results on the role of scale on turbulent boundary layer separation on the upper surface of an airfoil model are also discussed

The Peak Brightness and Spatial Distribution of AGB Stars Near the Nucleus of M32

The bright stellar content near the center of the Local Group elliptical galaxy M32 is investigated with 0.12 arcsec FWHM H and K images obtained with the Gemini Mauna Kea telescope. Stars with K = 15.5, which are likely evolving near the tip of the asymptotic giant branch (AGB), are resolved to within 2 arcsec of the nucleus, and it is concluded that the peak stellar brightness near the center of M32 is similar to that in the outer regions of the galaxy. Moreover, the projected density of bright AGB stars follows the visible light profile to within 2 arcsec of the nucleus, indicating that the brightest stars are well mixed throughout the galaxy. Thus, there is no evidence for an age gradient, and the radial variations in spectroscopic indices and ultraviolet colors that have been detected previously must be due to metallicity and/or some other parameter. We suggest that either the bright AGB stars formed as part of a highly uniform and coherent galaxy-wide episode of star formation, or they originated in a separate system that merged with M32.Comment: 9 pages of text, 3 figures.

Volcanic Stratigraphy and Age Model of the Kimama Deep Borehole (Project Hotspot): Evidence for 5.8 Million Years of Continuous Basalt Volcanism, Central Snake River Plain, Idaho

The Snake River Plain of central Idaho represents the world’s best example of a mantle hotspot track impinging upon continental crust and provides a record of bimodal volcanism extending over 12 Ma to the present. Project Hotspot recovered almost 2 km of continuous drill core from the Kimama borehole, located in central Idaho on the axial volcanic zone. The Kimama drill core represents the most complete record of mafic volcanism along the Yellowstone–Snake River Plain hotspot track. A total of 432 basalt flow units, representing 183 basalt flows, 78 basalt flow groups, and 34 super groups, along with 42 sediment interbeds are recognized using volcanic facies observations, stratigraphic relationships, borehole geophysical logs, and paleosecular variation in magnetostratigraphy. Rhyolite and other non-basaltic volcanic materials were not encountered in the drill core. Ages for six basalt lava flows were determined by 40Ar/39Ar using incremental heating experiments. Paleomagnetic inclination was measured on over 1200 samples collected at roughly 2-m-depth intervals, yielding mean values of paleosecular variation between ±50° to ±70° in Kimama flow groups, close to the expected 61° axial dipole average for the Kimama borehole location. Twenty-three magnetic reversals were identified and correlated to dated geomagnetic chrons and subchrons and compared with the 40Ar/39Ar radiometric ages. A linear fit to 40Ar/39Ar dates, geomagnetic chron and subchron boundaries, and volcanogenic zircon U-Pb ages defines a mean accumulation rate of ∼320 m/m.y. and extrapolates to a bottom hole age of 6.3 Ma. Average thicknesses of lithologic units increase from 2.7 m (sediment), 4 m (flow units), 10 m (flows), 23 m (flow groups), to 53 m (super groups). On average, one lava flow inundated the Kimama borehole location every 33 k.y. Intercalated sediments, ranging from 0.06 to 24.5 m thick, make up roughly 6% of the drill core and indicate lulls in local volcanic activity that may have lasted up to 77 k.y. Neutron and gamma-ray logs supplement observations from the drill cores: neutron logs document individual flow units through the contrast between massive flow interiors and more porous flow surfaces, and gamma-ray logs document the depth and thickness of sedimentary interbeds and high–K-Fe basalts. The 5.8 m.y. duration of basaltic volcanism in the Kimama drill core implies a steady rate of volcanism, indicating a relatively stable rate of mantle upflow along the lithosphere-mantle boundary in the wake of Yellowstone–Snake River Plain plume volcanism
