Onset Of Oscillations In Rayleigh-Benard Convection: Horizontally Unbounded Slab, Boyd F. Edwards, A. L. Fetter Jul 1984

Onset Of Oscillations In Rayleigh-Benard Convection: Horizontally Unbounded Slab, Boyd F. Edwards, A. L. Fetter

All Physics Faculty Publications

Rayleigh–Bénard convection in a laterally unbounded classical fluid layer with low Prandtl number P (ratio of kinematic viscosity to thermal diffusivity) is reexamined. An amplitude expansion with only a few normal modes yields lateral oscillations of the convective rolls, which are therefore only weakly nonlinear. For free boundary conditions, additional modes (absent for rigid boundaries) lead to long wavelength (‘‘hydrodynamic’’) oscillations, with explicit nonlinear distortions in the velocity and temperature fields. For oscillations with rigid boundaries, the finite critical wavenumbers are approximately independent of P for small P, and the calculated Rayleigh number, frequency, and wavenumber at onset agree well …

Mix Design Investigation - Roller Compacted Concrete Construction, Upper Stillwater Dam, Utah, United States Department Of The Interior, Bureau Of Reclamation Jun 1984

Mix Design Investigation - Roller Compacted Concrete Construction, Upper Stillwater Dam, Utah, United States Department Of The Interior, Bureau Of Reclamation

Dams

Upper Stillwater Dam will be the first concrete dam constructed by the Bureau of Reclamation utilizing the RCC (roller compacted concrete) construction technique. RCC is concrete with zero slump consistency, which is deposited in horizontal lifts and consolidated in place by a smooth drum vibrating roller. This method of construction was first proposed in the early 1970's [1, 2, 3]* and was demonstrated successfully in emergency spillway repairs at Tarbela Dam, Pakistan [3], in the construction of Shimajigawa Dam, Japan, and Willow Creek Dam, Oregon.

Correlations Of Phenolic Acids And Xylose Content Of Cell Wall With In Vitro Dry Matter Digestibility Of Three Maturing Grasses, Elizabeth A. Burritt, A. S. Bittner, J. C. Street, M. J. Anderson Jun 1984

Correlations Of Phenolic Acids And Xylose Content Of Cell Wall With In Vitro Dry Matter Digestibility Of Three Maturing Grasses, Elizabeth A. Burritt, A. S. Bittner, J. C. Street, M. J. Anderson

Wildland Resources Faculty Publications

Maturing reed canarygrass, Russian wildrye, and smooth bromegrass cell walls were analyzed for lignin, phenolic acids, and neutral sugars. Linear correlation between in vitro dry matter digestibility and the p-coumaric acid content was −.86. The correlation between in vitro dry matter digestibility and ratio of p-coumaric to ferulic acid was −.84. Samples with high percentages of lignin also contained high ratios of p-coumaric to ferulic acid. Thus, p-coumaric acid may be more important than ferulic acid in crosslinking lignin to structural carbohydrates. Percent xylose and in vitro dry matter digestibility also were correlated significantly in all three species. A Russian …

Anthology: A Collection Of Essays, Kathleen Mcgowan

Undergraduate Honors Capstone Projects

Last month, my roommate asked me if I wanted to join a new club she was forming. When I responded, "I really don't care," I was instantly initiated as Vice President, and quickly put to work. My assignment was recruitment. Aimlessly I wandered around the Utah State University campus randomly seeking out students to join the club. I asked them questions about their interests and aspirations. If they had any, they couldn't join. I asked them questions such as, "would you come to meetings?' and anyone who responded, "yes," was instantly rejected for caring too much. Within one week, I …

Nutritional Ecology Of The Northern Pocket Gopher: A Study Of Nitrogen Balance, Miki M. Stuebe May 1984

Nutritional Ecology Of The Northern Pocket Gopher: A Study Of Nitrogen Balance, Miki M. Stuebe

Biology

The northern pocket gopher, Thomomys talpoides, is probably not able to maintain nitrogen (N) balance in winter in northern Utah if it eats only belowground plant material typical of that found in the caches it makes. Gophers burrowing 10 h/day would meet about 81% of their daily N requirement on such a diet, which has a true N digestibility of 49.0%, and a biological value of 90.6%. However, gophers could easily meet N requirements in winter by consuming material only slightly higher in N than cached material. High-N material (both plant and animal matter) is probably available to most …


The Effects Of Altered Prey Availability And Shrub Architecture On Spider Community Parameters: A Field Experiment In A Shrub-Steppe Ecosystem, Kathryn Wing May 1984

The Effects Of Altered Prey Availability And Shrub Architecture On Spider Community Parameters: A Field Experiment In A Shrub-Steppe Ecosystem, Kathryn Wing

Biology

The effects of altered prey availability and shrub architecture on spider community parameters were studied in a field experiment in northeastern Utah. Treatments of 2 states of foliage density--"normal" and tied (= high density)--and 2 states of insect attractant-- control and baited--were applied to big sage shrubs (Artemisia tridentata) using a factorial experimental design. Temperature and humidity were not significantly different between the 2 types of shrub architecture. The species array and abundance of shrub insects were not significantly altered by the foliage density treatment. Shrubs with insect attractant had significantly larger insects (as measured by body length) …


Isozyme Variation Among Geographic Populations Of The Alfalfa Weevil, Hypera Postica (Gyllenhal), In Utah, John M. Stutz May 1984

Isozyme Variation Among Geographic Populations Of The Alfalfa Weevil, Hypera Postica (Gyllenhal), In Utah, John M. Stutz

Biology

The objectives of this study were to estimate the amount of genetic variation present among populations of the alfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae), and to determine the amount of divergence between these populations. The enzyme products of 25 loci (acid phosphatase, alcohol dehydrogenase-2, alcohol dehydrogenase-3, amylase-1, amylase-2, aldehyde oxidase, esterase-1, esterase-2, esterase-3, fumarase, glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, glutamate-oxaloacetate-transaminase, alpha-glycerophosphate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase, malate dehydrogenase-1, malate dehydrogenase-2, malate dehydrogenase-3, malate dehydrogenase-4, malic enzyme, superoxide dismutase, tyrosinase-1, tyrosinase-2, tyrosinase-3, xanthine dehydrogenase) were examined using polyacrylamide gel electrophoresis for four Utah alfalfa weevil populations; two from the north (Logan and Payson) …


Xylorhiza Glabriuscula Var. Linearifolia (Asteraceae - Astereae): Stabilized Hybrid Derivative Or Evolutionary Intermediate?, Tamalyn Stockton May 1984

Xylorhiza Glabriuscula Var. Linearifolia (Asteraceae - Astereae): Stabilized Hybrid Derivative Or Evolutionary Intermediate?, Tamalyn Stockton

Biology

Morphological, ecological, flavonoid, and cytological studies were conducted to determine the origin of Xylorhiza glabriuscula var. linearifolia. These data strongly suggest that X. glabriuscula var. linearifolia (2n = 12, 24) has a hybrid origin, the putative parental taxa being X. glabriuscula var. glabriuscula (2n = 12) and X. tortifolia var. imberbis (2n = 12). Variety linearifolia is intermediate to the latter taxa morphologically and ecologically. In addition, it has a partially additive profile of the flavonoids found in the parental taxa. All the major types of flavonoids found in the parental taxa are represented in variety linearifolia, but it …


A Comparison Of The Desiccation Resistances Of Three Species Of Crab Spiders Occuring Sympatrically In Northern Utah, Eric James Zurcher May 1984

A Comparison Of The Desiccation Resistances Of Three Species Of Crab Spiders Occuring Sympatrically In Northern Utah, Eric James Zurcher

Biology

Respiration rates, water contents, water loss rates, and abilities to withstand water loss were assessed at 15, 25, and 35 C for adults of three species of crab spiders occuring sympatrically on shrub-steppe vegetation in northern Utah. The three species, Misumenops lepidus (Thorell), Xysticus cunctator (Thorell), and Philodromus histrio (Latreille), differ in their apparent seasonal distributions, with M. lepidus being collected most frequently in spring and fall, X. cunctator appearing most frequently in summer, and P. histrio occuring in all seasons. Rates of oxygen consumption paralleled casual observations of the general rates of activities of these spiders. Hence the generally …
