Geochemical And Isotopic Characterization Of Shallow Basinal Brines From The Makgadikgadi Pans Complex, Northeastern Botswana: Determination Of The Sources Of Salinity, Loago N. Molwalefhe
Dissertations
Isotopes and chemical tracers have been used to constrain the sources and causes of salinity in shallow groundwater brine from the Makgadikgadi Basin, northeastern Botswana. The brine is massively rich in chloride and sodium, and moderately rich in carbonates, sulphate and potassium, and is distinctively poor in divalent cationic species. Various models that have been advanced to explain the origin of the brines include evaporative enrichment at the surface and density-induced infiltration, dissolution of evaporites, and trapped connate water.
This study presents the compositional variability and behaviors of ·the stable isotopes of carbon (S13C) and oxygen (S18 …
Synthesis Of Adenosine Derivatives As Transcription Initiators And Preparation Of 5 ' Fluorescein- And Biotin-Labeled Rna Through One-Step In Vitro Transcription, Faqing Huang, Guocan Wang, Tricia Coleman, Na Li
Synthesis Of Adenosine Derivatives As Transcription Initiators And Preparation Of 5 ' Fluorescein- And Biotin-Labeled Rna Through One-Step In Vitro Transcription, Faqing Huang, Guocan Wang, Tricia Coleman, Na Li
Faculty Publications
Expanding our previous finding of an adenosine-initiated transcription system, we now demonstrate that either the 5' site or the N6 site of adenosine nucleotides can be modified extensively without abolishing their ability to initiate transcription under the T7 phi2.5 promoter. Two series of amino derivatives of adenosine nucleotides were synthesized. Fluorescein and biotin groups were coupled to AMP derivatives through linkers of different sizes and hydrophobicities. Both fluorescein- and biotin-conjugated (at either the 5' or N6 site) adenosine nucleotides can act as efficient transcription initiators, producing fluorescein- and biotin-labeled RNA at the specific 5' end by a one-step transcription procedure, …

Status and Trends for Virginia Chesapeake Bay
The Virginia Chesapeake Bay and its tidal tributaries continue to show some environmental trends indicating progress toward restoration of a more balanced and healthy ecosystem. However, the Bay system remains degraded and some areas and indicators show continuing degradation. Progress in reducing nutrient inputs has made demonstrable improvements and we expect that continued progress toward nutrient reduction goals, along with appropriate fisheries management and chemical contaminant controls, will result in additional improvements to the Bay. An overall summary of findings for the major VA Bay tributaries (i.e. James, York, and Rappahannock Rivers) is bulleted below while the remainder of this …

Convergence Of Planar Domains And Of Harmonic Measure Distribution Functions, Ariel Barton
Convergence Of Planar Domains And Of Harmonic Measure Distribution Functions, Ariel Barton
HMC Senior Theses
Consider a region Ω in the plane and a point z0 in Ω. If a particle which travels randomly, by Brownian motion, is released from z0, then it will eventually cross the boundary of Ω somewhere. We define the harmonic measure distribution function, or h-function hΩ, in the following way. For each r > 0, let hΩ(r) be the probability that the point on the boundary where the particle first exits the region is at a distance at most r from z0. We would like to know, given a function f, whether there is some region Ω such that f is …

It is true that now most biology courses begin with the DNA molecule, and many chemistry courses introduce the notion of electronic orbitals in atoms and molecules, topics for which students are not well prepared, since most of them have not taken physics courses. Physics courses in turn relegate to the end some discussion of the structure of matter and electromagnetic interaction, or do not discuss that at all. Thus, students miss the overall picture.
The Mechanics Of Microeconomic Choice: A School Option Perspective, Ikwukananne I. Udechukwu
The Mechanics Of Microeconomic Choice: A School Option Perspective, Ikwukananne I. Udechukwu
Essays in Education
The development of this paper describes uniquely the mechanics of choice in the delivery of education services relative to the public school system and school options. Three components, which magnify choice, are consumer (parents), market (pupils), and producer (government). Macbeth (1989) notes that there are four groups of people who benefit from the education system, namely: (1) the pupil (children) (2) the parent (3) the owners of a school (government) and (4) society at large. The first three beneficiaries of the education system are appropriately linked to the three components of choice as illustrated in the model and discussed in …

Constraint Datalog In Trust Management, Scot Anderson
Constraint Datalog In Trust Management, Scot Anderson
School of Computing: Dissertations, Theses, and Student Research
Constraint Datalog holds an increasing role in Trust Management. We discuss several Trust Management systems and give a description of the environment and requirements for Trust Management. Constraint Datalog using addition constraints and approximation theory provides an expressive semantic with which to describe security policies for credentials, delegations and authorizations. Approximation theory allows halting in Constraint Datalog over addition constraints. We use the decision problem of Diophantine equations to show that Constraint Datalog over addition constraints is complete. Combining these two concepts provides an approximately complete, safe language. The problem of constant additions to closed languages provides reasons for using …

Clinical Effectiveness Of A Subperiosteal Anchorage Device, Monica Anne Witte
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this pilot study was to evaluate the clinical efficacy of a subperiosteal anchorage device, the palatal OnPlant™, during orthodontic retraction of protruding anterior teeth in cases requiring maxillary premolar extraction. Seven subjects (5 female, 2 male), ages 13 to 55, were selected for the study. The OnPlant was surgically placed in the mid-palatal region through a well-defined subperiosteal tunnel. Following the manufacturer recommended osseointegration period of four months, the OnPlant was uncovered and attached to the first molars by means of a transpalatal bar. Standard orthodontic treatment then commenced to retract the anterior teeth after the first …

An Investigation On The Impact Of The Structure Of Summative Student Evaluation On Self-Regulated Learning, John Charles Ritzler
An Investigation On The Impact Of The Structure Of Summative Student Evaluation On Self-Regulated Learning, John Charles Ritzler
Dissertations
Many hypotheses have been offered regarding the impact on learning caused by the most traditional practice of summative student evaluation, namely that of assigning marks to students. Sufficient evidence exists to suggest this practice often has detrimental effects. This study was designed to investigate the following three questions: (1) How does the method of summative student evaluation impact self-regulated learning in low-achieving high school mathematics students? (2) How does the cognitive level of the task mediate the relationship between method of summative student evaluation and self-regulated learning? (3) How does the length of time students are exposed to a method …
Likelihood-Based Specification Analysis Of Continuous-Time Models Of The Short-Term Interest Rate, Garland B. Durham
Likelihood-Based Specification Analysis Of Continuous-Time Models Of The Short-Term Interest Rate, Garland B. Durham
Finance
An extensive collection of continuous-time models of the short-term interest rate is evaluated over data sets that have appeared previously in the literature. The analysis, which uses the simulated maximum likelihood procedure proposed by Durham and Gallant (2002), provides new insights regarding several previously unresolved questions. For single factor models, I find that the volatility, not the drift, is the critical component in model specification. Allowing for additional flexibility beyond a constant term in the drift provides negligible benefit. While constant drift would appear to imply that the short rate is nonstationary, in fact, stationarity is volatility-induced. The simple constant …

Analysis Of Articles Published In Eight Selected Higher Education Journals On Selected Variables To Reveal Scholarly Development Of The Discipline, Kathy Brock Enger
Theses and Dissertations
The development of a discipline is reflected in its literature. Higher education is a fairly young discipline, as shown by the large amount of its literature beginning in the 1970s or later. Studying the literature of a discipline reveals various aspects of its development, and gives those engaged in its development an assessment of what is being done and who is doing it at a particular point in time. Using bibliometrics, or the literature as data, this dissertation examined articles in eight selected higher education scholarly journals in 1995 and 2000 to determine characteristics of the authors producing higher education …

Multiple Sclerosis, Time Of Day, And Subjectively Measured Sleep Effects On Neurological Functioning Using A Neuropsychological Battery, Julia R. Fitzgerald Smith
Theses and Dissertations
This study examined the impact of time of day of testing and subjectively measured daytime sleepiness and nighttime sleep on memory performance in adults with multiple sclerosis (MS) and in unimpaired adults. Thirty-four multiple sclerosis subjects (a.m.; N=17 and p.m.; N=17) and forty controls (a.m.; N=16 and p.m.; N=24) were assessed using the Logical Memory, Visual Reproductions, and Digit Span subtests of the Weschler Memory Scale-Ill, California Verbal Learning Test, and several questionnaires about mood, sleep, and physical symptoms. The primary result of this study was the absence of significant differences between the multiple sclerosis participants and controls on many …
