East Canyon Reservoir Water Intake Structure Final Environmental Assessment And Finding Of No Significant Impact, United States Department Of The Interior, Bureau Of Reclamation
East Canyon Reservoir Water Intake Structure Final Environmental Assessment And Finding Of No Significant Impact, United States Department Of The Interior, Bureau Of Reclamation
Environmental Assessments (UT)
The purpose of the proposed action is to authorize SWDC to build and operate facilities to deliver water to the Park City/Snyderville Basin area (Figure 1.2). The need for the proposed action is a growing demand for water in the Park City/Snyderville Basin area due to population growth and increased development of recreation facilities and vacation homes.
Simple Fit Of Data Relating Supermassive Black Hole Mass To Galaxy Pitch Angle, Harry I. Ringermacher, Lawrence R. Mead
Simple Fit Of Data Relating Supermassive Black Hole Mass To Galaxy Pitch Angle, Harry I. Ringermacher, Lawrence R. Mead
Faculty Publications
Seigar et al. have recently demonstrated a new, tight correlation between galactic central supermassive black hole (BH) mass and the pitch angle of the spiral arm in disk galaxies which they attribute to other indirect correlations. They fit a double power law, governed by five parameters, to the BH mass as a function of pitch. Noting the features of their fitted curve, we show that a simple linear proportion of the BH mass to the cotangent of the pitch angle can obtain the same fit, within error. Such a direct, elegant fit may help shed light on the nature of …
Diffraction Of Ocean Waves Around A Hollow Cylindrical Shell Structure, Song-Ping Zhu, Lewis Mitchell
Diffraction Of Ocean Waves Around A Hollow Cylindrical Shell Structure, Song-Ping Zhu, Lewis Mitchell
Faculty of Informatics - Papers (Archive)
In recent years, there has been renewed interest in problems of diffraction and radiation of ocean waves around structures, in relation to “green” power generation by Oscillating Water Column (OWC) devices. In this paper we present a first-order analytical solution for the diffraction of ocean waves around a hollow cylindrical shell structure suspended in an ocean of finite depth. By revisiting work done by Garrett (1970) on the problem of a bottomless harbor, but adopting a different and more direct method, we obtain the solution for the diffracted wave potential. Using the new approach, we analyze the dependence of the …
Establishment And Persistence Of Species-Rich Patches In A Species-Poor Landscape: Role Of A Structure-Forming Subtidal Barnacle, A. R. Davis, David. W. Ward

Some sessile invertebrates are capable of maintaining space in barren habitats produced by sea urchins, thereby creating species-rich patches in a species-poor landscape. We sought to determine the role of a large and common barnacle, Austrobalanus imperator, in the establishment and persistence of these species-rich patches. Barnacle density was modified in 2 experiments at sites in southeastern Australia. The first experiment concerned community establishment and involved the addition of barnacles in 4 densities (zero [control], low, medium and high) to plots on vertical rock surfaces. The addition of barnacles at ecologically realistic densities and spatial arrangements rapidly resulted in statistically …

Many reservoirs in arid regions experience highly variable water levels caused by seasonal inflow fluctuations and designated outflow requirements. At Shasta Lake, California, managers plant cereal-grain grassbeds on exposed drawdown shorelines to increase juvenile fish habitat, localize productivity, and increase invertebrate fish prey. To determine the efficacy of these plantings, the abundance of juvenile black basses Micropterus spp. (20–55 mm standard length) and the amount of periphyton and macroinvertebrate prey were compared among three treatment types: (1) planted grassbeds of cereal barley Hordeum vulgare; (2) artificial rope grassbeds, which eliminated physical deterioration and nutrient release; and (3) nonplanted control sites …

The crystal structure and the electronic and thermal properties of a high-quality polycrystalline TbFeAsO0.85 sample made by a high-pressure technique are investigated. The crystal structure, as determined by synchrotron X-ray powder diffraction, possesses a tetragonal unit cell (space group: P4/nmm) with lattice parameters of a=b=3.8851 Å and c =8.3630 Å. In order to elucidate the electronic structure and oxidation states of corresponding elements, X-ray absorption near-edge structure (XANES) spectra are presented. The XANES spectra confirm that the oxidation states of Fe, As, and Tb in the TbFeAsO0.85 sample are ~Fe2+, …
