Molecular Engineering Of Side-Chain Liquid Crystalline Polymers By Living Polymerizations, Coleen Pugh, Alan L. Kiste

Chemistry and Biochemistry

“Living” anionic, cationic, metalloporphyrin and ring-opening metathesis polymerizations have been used to prepare well-defined side-chain liquid crystalline homopolymers, block and graft copolymers and statistical copolymers. This paper analyzes their successes and failures by reviewing the mechanistic aspects and experimental conditions of each type of polymerization, and identifies other classes of mesogenic monomers that could be polymerized in a controlled manner in the future. The emerging structure/property relationships are then identified using well-defined SCLCPs in which only one structural feature is varied while all others remain constant.

The thermal transitions of liquid crystalline polymethacrylates, polynorbomenes and poly(viny1 ether)s reach their limiting …

An Assessment Of Elementary School Service-Learning Teaching Methods: Using Service-Learning Goals, Clifford Akujobi, Robert Simmons

Special Topics, General

The purpose of this study is to examine the progress and the difficulties teachers encounter in implementing service-learning programs in an urban elementary school. The study characterizes each service-learning project using the Kahne and Westheimer (1996) service-learning goals matrix. Based on our investigation, most of the service-learning projects at the upper elementary level emphasize emotional intelligence such as character building, social reconstruction, and additive experience. In contrast, service-learning projects at the lower elementary level focused more on social reconstruction and academic knowledge. While most service-learning projects at the upper levels create learning opportunities for students, teachers rarely challenged students' thinking …

Development Of Constructed Wetlands For The Reuse Of Wastewat R In Semi-Arid Regions, Byung J. Kim, Sherwood C. Reed, Thomas Andrew, Patrick D. Sullivan, U.S. Army Corps Of Engineers

All U.S. Government Documents (Utah Regional Depository)

Hill Air Force Base (AFB), UT, is responsible for the operation and maintenance of the Utah Test and Training Range (UTTR). The range contains waste-water treatment and disposal facilities that consist of two infiltration ponds operated in parallel, followed by an emergency overflow basin that safeguards against unexpectedly high flow rates. A previous evaluation concluded that the existing facilities should be replaced, at a relatively high cost and with no possibility for beneficial water reuse. The U.S. Army Construction Engineering Research Laboratories (USACERL) was requested to further evaluate the system and to identify cost-effective, feasible alternatives. USACERL researchers identified a …

Logging Utilization - Utah, 1993, United States Department Of Agriculture, Forest Service

Forestry

Data collected on 20 logging operations in Utah in 1993 provided board-foot and cubic-foot conversion factors of log scale and factors to apply to harvest volume estimates to obtain removals estimates. The components of timber products and removals, obtained by application of these factors to the 1992 Utah timber harvest, are included. Additional findings, presented in table form, are the diameter distribution of trees removed from growing stock per thousand cubic ft of products and the volume of logging residue in pieces 6 ft and longer as a proportion of product volume. Survey methods and estimates of data reliability are …

Utah Timber Production And Mill Residue, 1992, United States Department Of Agriculture, Forest Service

House log volume was 1.6 million cubic feet (8.2 million board feet). Lodgepole pine comprised 48 percent, Uintah County 29 percent, and National Forest lands 78 percent of the harvest. Mill residue volume was 7 million cubic feet, 82 percent of which was used, most for fencing, firewood, animal bedding, or industrial plant fuel.

Potential Regional Impacts Of Global Warming On Precipitation In The Western United States, United States Department Of The Interior, Bureau Of Reclamation

Meterology

Snow and melting of the snowpack provide the principal supply of water to much of the Western United States. Whether global warming threatens this water supply is the focus of this research. This study builds upon a previous Global Climate Change Response Program investigation. Charts were generated of four geopotential height parameters for a domain covering the eastern North Pacific Ocean and western North America. Out of 131 total winter months (from 1946-89), 35 were selected as analogues.

Monthly mean precipitation values for areas in western Montana, northern Utah, and east central Arizona were compared with median values for the …

Mathematical Instantons With Maximal Order Jumping Lines, A. Prabhakar Rao

Mathematics and Statistics Faculty Works

A mathematical instanton bundle on P (over an algebraically closed field) is a rank two vector bundle ε on P with c = 0 and with H (ε) = H (ε(-2)) = 0. Let c (ε) = n. Then n > 0. A jumping line of ε of order a, (a > 0), is a line ℓ in P on which ε splits as script O sign (-a)⊕script O sign (a). It is easy to see that the jumping lines of ε all have order ≤ n. We will say that ε has a maximal order jumping line if it has a …

Lyapunov Exponents Of Linear Stochastic Functional-Differential Equations. Ii. Examples And Case Studies, Salah-Eldin A. Mohammed, Michael K. R. Scheutzow

Articles and Preprints

We give several examples and examine case studies of linear stochastic functional differential equations. The examples fall into two broad classes: regular and singular, according to whether an underlying stochastic semi-flow exists or not. In the singular case, we obtain upper and lower bounds on the maximal exponential growth rate $\overlineλ₁$(σ) of the trajectories expressed in terms of the noise variance σ . Roughly speaking we show that for small σ, $\overlineλ₁$(σ) behaves like -σ² /2, while for large σ, it grows like logσ. In the regular case, it is shown that a discrete Oseledec …

Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey

Arkansas Water Resources Center Technical Reports

Mercury (Hg) contamination of fish is a widespread problem throughout much of the United States and the world (Louisiana WWW page, 1997). Levels ofHg in fish suffic1ent to exceed the FDA action level of 1 mg kg-1 have been found in many water bodies, including some in Arkansas and Louisiana. As a result of the serious public health ramifications for developing fetuses and for people that subsist on native fish, fish consumption advisories due to Hg contamination have been issued in 29 states. Contamination of surface water bodies by Hg results from deforestation, forest fires, fossil fuels, mining, natural emissions …

Odour Detection In The Desert Locust, Schistocerca Gregaria: Antennal Structure And Function, Samuel A. Ochieng'

All PhD Dissertations

Insects are among the most successful organisms in the animal Kingdom. Their capacity to survive and reproduce depends greatly on their ability to identify and respond selectively to cues from a heterogeneous environment. They can identify conspecifics and mates, differentiate between hosts, both plant and animal, and distinguish between many microclimatic factors such as variation in humidity, temperature and airflow. All these factors are attributed to the complexity of their sensory systems that facilitate both simple and complex behaviours. The insect is, however, isolated from its external surroundings by a cuticular structure that is relatively impermeable to chemical sensation. But …

Bang-Bang Control Development Of Permeability Changes In A Membrane Model, Robert Melendy

Faculty Publications - Department of Electrical Engineering and Computer Science

The application of systems and control theory to membrane physiology is presented here. Modeling efforts have focused on describing those physiologically realistic mechanisms which govern the regulation of membrane permeability in nerve. The motivation behind identifying such mechanisms lies in understanding the morphology of neural activity on a meaningful and analytically tractable level. The suggested merit of integrating control theory into the analysis lies in providing how a membrane effectively adapts to changes in permeability and through what governing mechanisms. The value in producing such an understanding lies in mirroring biological reality in a more formal manner than could be …
