An Investigation Of The Dynamic Response Of The Activated Sludge Process, Tin-Bai Pan

Dissertations

A new mathematical model, derived from first principles of mass balance, is proposed for describing the mass transfer response of an activated sludge aeration tank in terms of a fluidized bed. The operational data to verify the proposed model were taken from an existing conventional wastewater treatment plant and a bench scale pilot plant.

The mass transfer rate, (K_dA_s), was presented by an empirical dimensionless group function as follows:

((K_dA_s)D_p/D_v) = fA_c (uD_p/ν)a ((ν/D_ν)(MLSS))^b

Or

Sh = f(A_c/A_s ) …

Impact Of The 1975 Wallsburg Fire On Antelope Bitterbrush (Purshia Tridentata), Fred J. Wagstaff

Great Basin Naturalist

Antelope bitterbrush (Purshia tridentata) is a preferred browse species that is susceptible to decreases in population density due to fire. The reduction in density of this species due to fire was determined by sampling areas within and adjacent to the burn. The 1975 burn caused a significant reduction in the population density of bitterbrush. It was also determined that rate of growth was lower for plants within the burn.

A New Species Of Fossil Chrysothamnus (Asteraceae) From New Mexico, Loran C. Anderson

Great Basin Naturalist

The new, presumably extinct species, Chrysothamnus pulchelloides, is formally described and illustrated. The plant materials came from Holocene packrat middens. Anatomical and phyletic relationships of the fossil species to extant taxa are discussed.

New American Bark Beetles (Coleoptera: Scolytidae), With Two Recently Introduced Species, Stephen L. Wood

Great Basin Naturalist

Species named as new to science include: Conophthorus michoacanae, C. teocotum, Hylesinus aztecus (Mexico), Phloeocleptus punctatus (Costa Rica), Pseudothysanoes atomus (Venezuela), P. leechi (California), Pityogenes mexicanus, Araptus speciosus, Amphicranus spectus (Mexico), and Xyleborus praestans (Panama). Also reported are the first records of the notorious Xylosandrus compactus (Eichhoff) from South America (Brazil), and the first American records of Xyleborus fornicatus Eichhoff (Panama) and X. validus Eichhoff (New York and Pennsylvania).

Flood Frequency And The Assemblage Of Dispersal Types In Hanging Gardens Of The Narrows, Zion National Park, Utah, George P. Malanson, Jeanne Kay

Great Basin Naturalist

Hanging gardens of the Narrows, Zion National Park, Utah, are plant communities growing at permanent seeps on the canyon walls. The gardens are isolated from each other and from other plant communities by vertical expanses of sandstone. Gardens consist mostly of herbaceous species less than 1 m tall. Though not individually species-rich, the hanging gardens are diverse as a group, and very dissimilar.

This study considers two explanations of the heterogeneous distribution of species in hanging gardens. The assemblages of dispersal types in gardens of different spatial attributes and disturbance frequencies are examined. The G_H statistic, a log likelihood …

Zonation Patterns In The Potholes Of Kalsow Prairie, Iowa, Jack D. Brotherson

Great Basin Naturalist

Kalsow Prairie, a mesic prairie remnant in central Iowa, was acquired by the state in 1949 and later established as a botanical reserve. This study concerns a complex of 14 potholes and adjacent drainage areas within the prairie. The potholes varied in depth and degree of fill and are thus useful in studies of plant succession. All 14 potholes exhibit zonation patterns. A total of 36 transects were taken in the various community zones. Canopy cover data were taken in every zone. The zones are ordinated into three-dimensional space as well as clustered. Interspecific association patterns are elucidated. A successional …

Terrestrial Vertebrate Fauna Of The Kaiparowits Basin, N. Duane Atwood, Clyde L. Pritchett, Richard D. Porter, Benjamin W. Wood

Great Basin Naturalist

This report includes data collected during an investigation by Brigham Young University personnel from 1971 to 1976, as well as a literature review. The fauna of the Kaiparowits Basin is represented by 7 species of amphibians (1 salamander, 5 toads, and 1 tree frog), 29 species of reptiles (1 turtle, 16 lizards, and 12 snakes), 183 species of birds (plus 2 hypothetical), and 74 species of mammals. Geographic distribution of the various species within the basin are discussed. Birds are categorized according to their population and seasonal status. Avian habitat relationships are discussed, and extensions of range are reported for …
