A Response Surface Study Of Extruded Corn Starch/Skim Milk Powder Blends, Sachin Singh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Skim milk was ultrafiltered to three lactose/protein ratios and spray dried. The skim milk powder was extruded with pearled corn starch at different moisture contents, protein contents, lactose/protein ratios, and feed rates (control variables). Response surface methodology and a central composite in cube experimental design were used. This design required 30 experimental runs with 16 factorial points, 8 axial points, and 6 center points for replication. The physical and functional properties evaluated were expansion ratio, product temperature, bulk density, color, shear stress, viscosity, and water absorption index (response variables). Scanning electron microscopy was done to evaluate the microstructural attributes of …

Effects Of Nonfat Dry Milk, Whey Protein Concentrate, And Calcium Caseinate On Color And Texture Of Turkey Rolls, Brent Neeley Dobson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two studies were conducted to evaluate the effects of milk solids on restructured and emulsified turkey rolls. the milk solids used were nonfat dry milk (NFDM), whey protein concentrate (WPC), and calcium caseinate (CC). Turkey rolls consisted of 100% breast meat or 90:10 or 70:30 breast-to-thigh, salt (1%), water (10%), internal or cluster fat (10%), and 3% of various milk solids (WPC, NFDM, CC).

The objectives of these studies were to 1) determine which ratio between light and dark meat is preferred; 2) determine which of milk solids evaluated will permit the highest level of dark meat incorporation into evaluated …

Alcohol, Abstinence, Efficacy, And Social Normative Expectancies: The Relationship To Alcoholics' Level Of Drinking Following Inpatient Treatment, Martin John Toohill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been argued that individuals receiving traditional alcohol treatment do not necessarily perceive life-long abstinence from alcohol as a favorable treatment outcome, and that negative expectations associated with this abstinence goal may have an adverse effect on treatment outcome. However, "abstinence expectancies" have never been systematically explored. This study used the Theory of Planned Behavior to investigate the relationship between the abstinence outcome expectancies of alcoholics beginning treatment and subsequent alcohol consumption. The independent and combined effects of abstinence outcome expectancies, alcohol outcome expectancies, self-efficacy expectancies (to abstain from alcohol use), and the normative beliefs of individuals beginning inpatient …

The Predictive Validity Of The Battelle Developmental Inventory As A Measure Of Adaptive Behavior : A 2-3 Year, Longitudinal Comparison With The Scales Of Independent Behavior, Clarice E. Jentzsh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the last 5 years, researchers have given increased attention to preschool assessment. One test, the Battelle Developmental Inventory, has become increasingly popular for use with preschool-age children. Despite its frequent use by early intervention programs, few researchers have studied the technical adequacy of the Battelle. The predictive validity of the Battelle was examined, using 154 children with disabilities. Scores on the Battelle for children 3 to 5 years of age were compared with scores on the Scales of Independent Behavior administered to the same children 2 to 3 years later. Moderate to strong relationships were found between the scores. …

Family Perspectives Of The Professional-Paraprofessional Partnership Model Of Home-Based Early Intervention Service Delivery, Amy Sanford Walters

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current legislation regarding early intervention services has focused on the family unit, rather than the individual child, as the recipient of services. A model of family-centered care has been adopted and as a result, new models for service delivery have been developed. The present study examined family perspectives of the professional-paraprofessional partnership model, and assessed the ecological validity of this model as it relates to the basic principles of family-centered care. Families who participated in an early intervention program that utilized the professional-paraprofessional partnership model were interviewed upon program completion. Families reported receiving a wide range of child and family …

Study Of Circulating Antibodies To Heat-Shock Proteins 60 And 70 In Autistic Subjects, Fang-Yi Chiu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Autism is a behavioral syndrome characterized by a severe impairment of reciprocal social relations, and of verbal and nonverbal communications. Many different etiologic factors such as viral infection and genetic predisposition have been proposed to explain the development of this disorder. Immune abnormalities, such as a decreased lymphoblastic response to T-cell mitogen, defective antibody responses to rubella vaccine, and decreased numbers of T lymphocytes, also have been identified in a subpopulation of patients with autism, which implies that the development of autism in some cases may be due to autoimmune mechanisms.

Recent evidence suggests that immune response to the heat-shock …

Immune And Endocrine System Responses To Acute Skin-Temperature Reductions And Thermal Biofeedback, Kenneth E. Bell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine the effects of the cold pressor test on skin temperature, natural killer cell activity, plasma concentrations of interleukin-1 and cortisol, and the numbers of white blood cells, CD3+ cells, CD4+ cells, CD8+ cells, and CD56+ cells in the peripheral blood. In addition, the study examined whether thermal biofeedback, when presented following the cold pressor tests, would mitigate the effects of the cold pressor tests.

Four male university students completed pretest psychological inventories and were pretrained during nine laboratory sessions to increase their skin temperature to 95 degrees Fahrenheit. During the experiment, blood …

Examining The Effects Of A Self-Study Package On Teachers' Use Of Coincidental Teaching In Preschool Classrooms, Laurie A. Dinnebeil

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation examined the effects of a self-study package on three early childhood special education teachers' use of coincidental teaching with preschool children with, or at risk for, disabilities. The results of this investigation showed that all teachers performed better on a posttest than a pretest measure for knowledge of coincidental teaching. Teachers were also able to complete a series of written assignments pertaining to coincidental teaching. Increases in coincidental teaching knowledge, however, were not accompanied by changes in coincidental teaching behavior for two of the three teachers. Participating teachers reported satisfaction with the self-study package as an instructional format …

Developing A Benchmark For Evaluating The Performance Of Parallel Computers, D. Ladd Williamson

Undergraduate Honors Capstone Projects

This paper discusses the development of a portable suite of benchmarking programs for parallel computers. Comparative measurement of the performance of parallel computing systems has been limited because of the great diversity of architectures and of processor interconnection schemes. One solution is to translate benchmark codes into a consistent and portable parallel language. This paper reports on progress in developing such a portable suite of benchmarks. An extensive introduction to parallel computing is included as an appendix, to provide a thorough understanding of the factors complicating development of the performance suite. Key to the development was the use of p4, …

Scanning Electron Microscopic Examination Of The Putative Olfactory Structures Possessed By The Phorid Fly, Megaselia Halterata (Diptera, Phoridae), R. M. Pfeil, R. A. Walsh, R. O. Mumma

Scanning Microscopy

The antennae, palps, and mouth parts sheath of Megaselia halterata (Wood) (Diptera, Phoridae) were examined by scanning electron microscopy to locate putative olfactory sensilla (POS). Most POS were found on the third antenna! segment (Johnston's organ). These POS included a lanceolate peg, a bulbous peg, and two types of pit sensilla. Female flies could be distinguished from males by the predominance of the lanceolate peg on the female Johnston's organ. One type of pit sensillum with a single exterior opening was located below the cuticular surface and housed several pegs. The other type of pit sensillum was domed with a …

The Father Of ‘Talk Show Democracy’—On The Line With Larry King, Ted Pease

Journalism and Communication Faculty Publications

IN THE AFTERMATH of what surely was the most extraordinary presidential campaign ever for the American news media, the Larry King story-like the man himself-has taken on almost mythic proportions: Horatio Alger Makes Good. Real good. Today, the mantle of media greatness rests easy on the selfdescribed "Jewish kid from Brooklyn" in the wake of events that defined the "top banana of talk show hosts" as the undisputed kingmaker of the 1990S. Consider: During the presidential race, Ross Perot announced his candidacy (twice) on "Larry King Live"; after belittling the idea, an uncomfortable (and, finally, desperate) George Bush came on …

The Presidency In The New Media Age, Everette E. Dates, Ted Pease

Journalism and Communication Faculty Publications

Nowhere are the differences between journalism and history more evident than in assessments of the presidency of the United States. If journalism is generously described as "history in a hurry," so is it shortsighted and sloppy as it lurches forward, gathering news in bits and pieces, coming to conclusions based on short-term accomplishments and the court of public opinion.

Microvascular Pattern Of The Retina In The Japanese Monkey (Macaca Fuscata Fuscata), Shigenori Okada, Yoshikuni Ohta

Scanning Microscopy

The microvascular architecture of the retina in the Japanese monkey was revealed using scanning electron microscopy of microvascular corrosion casts.

At the optic nerve disc, the central retinal artery radiated to four primary retinal arterioles: the superior and inferior temporal arterioles and superior and inferior nasal arterioles. A dense retinal capillary network showed regional differences in density. The capillary networks observed were divided in four parts: the optic nerve disc, macula, equator, and ora serrata. At the optic nerve disc, the network was a multi-laminar structure containing the radial peripapillary capillaries in parallel with the nerve fibers at the innermost …

Integrated Embedding Optimization Applied To Salt Lake Valley Aquifers, A. Gharbi, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

The embedding optimization modeling approach is adapted to aid sustainable groundwater quantity and quality management of complex nonlinear multilayer aquifers. Implicit block-centered finite difference approximations of the quasi three-dimensional unsteady flow equation and Galerkin finite element approximations of the two-dimensional advection-dispersion transport equation are embedded directly as constraints in the model. Also used are nonlinear constraints describing river-aquifer interflow, evapotranspiration, and vertical flow reduction due to unconfinement. These circumvent use of large numbers of integer variables. The use of both linear and nonlinear formulations in a cyclical manner reduces execution time and improves confidence in solution optimality. The methodology is …

Optimal Freeze-Drying Of Cryosections And Bulk Specimens For X-Ray Microanalysis, L. Edelmann

Scanning Microscopy

Electron microscopic investigations of rapidly frozen specimens of striated muscle, either frozen-hydrated or obtained after different dehydration procedures, have shown that the subcellular distribution of the main cellular cation K⁺ or its surrogates Rb⁺, Cs⁺, or Tl⁺ does not follow the water distribution but follows certain proteins. Conflicting results obtained by X-ray microanalysis of freeze-dried cryosections are explained by showing that freeze-drying of bulk specimens and cryosections must be carried out for rather long periods at low temperature in order to avoid severe shrinkage and ion redistribution artefacts. Proposals for future freeze-drying studies are …

Ultrastructural Alterations Of Golgi Apparatus In The Nerve Cells Of Cerebral Cortex In Human Hydrocephalus. A Qualitative Study Using Cortical Biopsies, Orlando J. Castejon, Melecio Diaz, Consuelo Valero

Scanning Microscopy

Cortical biopsies of 17 patients with clinical diagnosis of hydrocephalus and associated pathology were examined in the transmission electron microscope. Moderately and severely edematous neurons showed relevant structural changes of the Golgi apparatus consisting of either discrete or marked dilation, fragmentation, and partial disappearance of Golgi stacked cisternae. In Arnold-Chiari malformation small Golgi complexes of vesicular type and atrophic changes were observed in severely edematous neurons. The microtubules appeared intact, suggesting differential response between Golgi complex and microtubules. Atrophic changes of the Golgi complex coexisted with degenerated presynaptic endings.

Electron Probe X-Ray Microanalysis Of Epithelial Cells: Aspects Of Cryofixation, Karl Zierold, Hartmut Hentschel, Frank Wehner, Armin Wessing

Scanning Microscopy

Content and distribution of diffusible ions in epithelial cells were studied by scanning transmission electron microscopy and energy dispersive electron probe X-ray microanalysis of freeze-dried cryosections from trout kidney, rat liver and Malpighian tubules of Drosophila larvae. Cryofixation of small excised kidney and liver samples by rapid immersion into liquid propane resulted in intracellular K/Na-ratios < 1. In contrast, K/Na-ratios > 7 were obtained after in situ cryofixation by means of a cryopunching device which allows tissue pieces to be frozen during excision from the intact organ. Isolated hepatocytes cryofixed in a small droplet of culture medium had a K/Na-ratio of 3.7. After culturing the hepatocytes, …

Classification Using Set-Valued Kalman Filtering And Levi's Decision Theory, T.K. Moon, Scott E. Budge

Electrical and Computer Engineering Faculty Publications

We consider the problem of using Levi's expected epistemic decision theory for classification when the hypotheses are of different informational values, conditioned on convex sets obtained from a set-valued Kalman filter. The background of epistemic utility decision theory with convex probabilities is outlined and a brief introduction to set-valued estimation is given. The decision theory is applied to a classifier in a multiple-target tracking scenario. A new probability density, appropriate for classification using the ratio of intensities, is introduced.

Epistemic Decision Theory Applied To Multiple-Target Tracking, T. K. Moon, Scott E. Budge, W. C. Stirling, J. B. Thompson

Electrical and Computer Engineering Faculty Publications

A decision philosophy that seeks the avoidance of error by trading off belief of truth and value of information is applied to the problem of recognizing tracks from multiple targets (MTT). A successful MTT methodology should be robust in that its performance degrades gracefully as the conditions of the collection become less favorable to optimal operation. By stressing the avoidance, rather than the explicit minimization, of error, the authors obtain a decision rule for trajectory-data association that does not require the resolution of all conflicting hypotheses when the database does not contain sufficient information to do so reliably. This rule, …

Photoemission Measurement Of Equilibrium Segregation At Gesi Surfaces, J. E. Rowe, D. Mark Riffe, G. K. Wertheim, J. C. Bean

All Physics Faculty Publications

Photoemission spectroscopy is used to demonstrate that Ge segregates to the first atomic layer of Ge_0.5Si_0.5(100)2×1 and that the second layer is predominantly Si. Comparison of the resolved signals from the dimer atoms of the reconstructed (100)2×1 surfaces of Ge, Si, and equiatomic Ge‐Si alloy shows that the surface layer of the alloy is extremely Ge rich and the second layer is occupied mainly by Si atoms. This result is in good agreement with theoretical predictions.
