Abstract:

Of the estimated 1100 species of mealybugs, approximately 6% are described as possessing degenerative legs and antennae in the adult female developmental stage or having lost these structures altogether. Fifteen genera composing 63 species are often separated into their own taxonomic group based on these vestigial features (e.g., Sphaerococcinae), and are collectively known as the "legless" mealybugs. A comparative morphological analysis of adult females was undertaken to clarify the taxonomic placement of these species and to determine their relationships. Methods were included on collecting, preserving, slide-mounting, and measuring specimens, and on preparing illustrations. Keys to genera and species of "legless" mealybugs were developed. Reduction or loss of legs and antennae apparently occurred convergently in response to similar environmental conditions and was not found supportive of homogeneity in the "legless" group as a whole. However, the genera Chaetococcus Maskell, Idiococcus Takahashi & Kanda, Kermicus Newstead, Serrolecanium Shinji, Tangicoccus Kozar & Walter, and a newly established genus share many characteristics and were treated as the tribe Serrolecaniini Shinji. The adult females of 13 species contained in these genera were redescribed, with illustrations produced for 12. A phylogenetic analysis of the tribe showed that converse to simplification in appendages, adaptations in other features (e.g., latero-projecting lobes and a caudally-directed vulva) probably developed to increase reproductive success and survivorship. The genera Acinococcus Williams, Antonina Signoret, Antoninoides Ferris, Cypericoccus Williams, Nesticoccus Tang, Paludicoccus Ferris, Parapaludicoccus Mamet, Peridiococcus Williams, Pseudantonina Green, and Sphaerococcus Maskell are not closely related to one another or to members of the tribe Serrolecaniini based on adult female morphology. These 10 genera and their type species were redescribed, and illustrations produced for all but Nesticoccus sinensis Tang. Comments or redescriptions are provided for the 21 additional species that comprise these genera; however, the taxonomic placement of 18 additional species erroneously assigned to Pseudantonina and Sphaerococcus is uncertain. Lectotypes were designated for Antonina crawi Cockerell, A. graminis Parrott, A. phragmitis Marchal, A. purpurea Signoret, A. waterstoni Newstead, Jdiococcus bambusae Takahashi & Kanda, Pseudantonina bambusae Green, Pseudolecanium disticlium Kuwana, and Sphaerococcus ethelae Fuller. A replacement name was proposed for the junior homonym Antoninella Sulc. The species names Antonina anceps Green, Antonina maritima Green, and Jdiococcus maanshanensis Tang & Wu are considered junior synonyms. Two species of Serrolecanium were described, and a new genus was established for the placement of Serrolecanium jiuhuaensis Wu and Serrolecanium sasae (Siraiwa). Six new name combinations are also made. Ph. D.

Abstract:

Supercritical fluid extraction (SFE) is becoming an attractive alternative to conventional solvent extraction for many reasons. These reasons include advantages of speed, the ability to be automated more easily than conventional solvent extractions and the lack of solvent disposal after the extraction has been performed. At this date SFE is performed in a multitude of ways with no one method out performing the others. The different ways in which SFE is performed is reviewed. Supercritical fluid extraction of analytes from aqueous solution has not received much attention. The design of a system which allows for the extraction of analytes from aqueous solution has been explored in this thesis. Several related areas (injection techniques for supercritical fluid chromatography and on-line SFE) were also developed. The injection port of a supercritical fluid chromatograph was modified to provide better ( more reproducible) sample introduction. For a 100 ppm 3,5-nitrobenzamide solution in methylene chloride the area reproducibility was increased from 3.2% RSD for the unmodified valve to 0.74% RSD for the modified valve. The method also resulted in a more narrow solvent front as well as an increase of 10% in the number of theoretical plates of the system. On-line SFE\SFC was explored as one possible configuration for the extraction of analytes from aqueous solution. Solvent elimination injection (SEI), was developed for SFC. The difference in vapor pressure between the analytes and solvent allowed for the solvent to evaporate and be transported form the system while the analytes were collected on various traps. After evaporation of the injection solvent the analytes were flushed onto a chromatographic column. SEI allowed for the reproducible injection of larger volumes of sample (solvent and analyte) into the system. SEI allowed for different hardware configurations to be tested without performing an actual supercritical fluid extraction. An off-line solid phase trapping system for SFE was developed. The system trapped the analytes from the SFE effluent onto a solid phase extraction cartridge. The cartridge could then be rinsed in a normal fashion to elute the analytes of interest. Trapping in this way was found to allow for faster extraction rates than liquid trapping. The efficiency of the trapping mechanism was found to be dependent upon the temperature of the trap, the chemical functionality of the phase bonded io the silica and the nature of the analytes. A system which allowed for the extraction of moderate volumes (3-5 mL) of aqueous solution was developed. A test solution of phenols was used to evaluate the system. The extractability of the phenols was found to be a function of pressure of the system and the chemical nature of the phenol. A decrease in extractability of the phenols was found to take place at pressures greater than 250 atm. The distribution coefficient of phenol was found to increase steadily through 400 atm. A decrease in surface area of the supercritica1 fluid passing through the aqueous solution was thought to be responsible for the apparent contradiction in behavior. Ph. D.

Hernandez, Ruiz Ruth. "Reliability assessment under incomplete information: an evaluative study." Thesis, Virginia Tech, 1993. http://hdl.handle.net/10919/41531.

Full text

Abstract:

Traditionally, in reliability design, the random variables acting on a system are assumed independent. This assumption is usually poor because in most real life problems the variables are correlated. The available information, most of the time, is limited to the first and second moments. Very few methods can handle correlation between the variables when the joint probability density function is unknown. There are no reports that provide information of the accuracy of these methods. This work presents an evaluative study of reliability under incomplete information, comparing three existing methods for calculating the probability of failure: The method presented by Ang and Tang which assumes the correlation between the variables to be invariant; Kiureghian and Liu/s method which accounts for the change in correlation and; Rackwitz's method under the assumption of independence. We have also developed a new algorithm to generate random samples of correlated random variables when the marginal distributions and correlation coefficients of these variables are specified. These samples can be used in IVlonte Carlo simulation which is a tool for comparison of the three methods described above. This Monte Carlo simulation approach is based on the assumption of normal joint probability density function as considered by Kiureghian and Liu. To examine if this approach is biased towards Kiureghian and Liu, a second Monte Carlo simulation approach with no assumption about the joint probability density function is developed and compared with the first one. Both methods that account for correlation show a clear advantage over the traditional approach of assuming that the variables are independent. Moreover, Kiureghian and Liu's approach proved to be more accurate in most cases than Ang and Tang's method. In this study, it is also shown that there is an error in calculating the safety index for correlated variables when either one of the methods in study is implemented, because the joint probability density function of the random variables is neglected.

Abstract:

The purpose of this study was two-fold: firstly, the MOCVD deposition behavior of Pb(thd)2 was studied in detail and a one-dimensional kinetic model was proposed to successfully predict the effect of processing conditions on the deposition rate profile for PbO. Assuming the surface reaction is the rate-limiting step in the process, the effective activation energy for the process, Ea, was found to be 82 kJ/mol while the preexponential rate constant was found to be 33 g/cm2/min (0.15 moVcm2/min). The process was found to consistently produce a combination of the high temperature, orthorhombic modification of lead monoxide with randomly oriented plates of tetragonal lead monoxide. TEM electron diffraction was used to investigate the crystal orientation of the individual plates which was found to be in the plane normal to the <201> zone. Secondly, the deposition behavior of PbTi03 and the resulting film structure and properties were investigated. Pb(thd)2 was used in conjunction with titanium ethoxide (Ti(OEt)4) as a titanium source. Stoichiometric lead titanate films which were found to be smooth, specular and transparent, and well-adhered were deposited on a variety of substrates by careful control of the experimental conditions. Film structure, composition, and thickness were studied and correlated to changes in various experimental parameters. Additionally, a high temperature regime at which the film stoichiometry is relatively insensitive to experimental conditions was found to occur. The effects of post-annealing on the as-deposited films including compositional changes, morphological changes and crystal structure was also studied. Some problems were obtained with film peeling on the ruthenium oxide (Ru02)-coated substrates which could be alleviated somewhat by the use of (100) oriented silicon wafer rather than (111) oriented silicon; a possible mechanism to explain this behavior is also suggested. Optical properties were obtained using UV -VISNIR transmission and reflectance spectroscopy; the ferroelectric hysteresis behavior of the films was observed using standard R T -66 A test equipment.

Abstract:

This study examined a neglected area in long term care and adult day care research: staff development. The specific purposes of this study were to describe the provision of a comprehensive staff development program in adult day care centers in Virginia in order to (a) differentiate those centers providing only the minimum required inservice training from those centers providing more comprehensive staff development programs and (b) define what meaning is placed upon staff education programs by center administrators. A mail survey design was used for this study. The questionnaire developed for the study has three sections: (a) center characteristics, (b) staff characteristics, and (c) the meaning of staff development. Quantitative analysis was conducted on the first two sections while qualitative analysis was used to examine the final section. A conceptual model for adult day care staff development programs was also developed for the study. The model was used to compare the staff development programs across adult day care centers in Virginia. The sample included all licensed adult day care center administrators in Virginia (n=43). The total response rate for this survey was 88%. Results were discussed in terms of the provision of staff development programs, as well as the meaning that was placed on staff development by the responding center administrators. The results showed that much importance is placed upon staff development programs by the center administrators and they follow through with this by providing a well rounded staff development program for their staff.

Abstract:

This thesis seeks to create an environment that encourages the learning process by addressing issues of emotional and physical well-being. The concept implies that success in learning can be linked to the environment of an elementary school. The building does not have to teach by itself, but merely facilitate the learning process through the making of a comfortable environment. Designing an elementary school demands that the architect look at the world through the eyes of a child. If the architect considers the scale of the building, both in terms of size and perception, the school becomes an oasis of security for the child that inspires intellectual growth. By integrating environmental design issues that are traditionally ignored in contemporary schools, like natural ventilation or daylighting, the school becomes less of an institution and more like a home.

Full text

Abstract:

In drug-testing experiments the primary responses of interest are efficacy and toxicity. These can be modeled as a bivariate quantal response using the Gumbel model for bivariate logistic regression. D-optimal and Q-optimal experimental designs are developed for this model The Q-optimal design minimizes the average asymptotic prediction variance of p(l,O;d), the probability of efficacy without toxicity at dose d, over a desired range of doses. In addition, a new optimality criterion, T -optimality, is developed which minimizes the asymptotic variance of the estimate of the therapeutic index. Most experimenters will be less familiar with the Gumbel bivariate logistic regression model than with the univariate logistic regression models which comprise its marginals. Therefore, the optimal designs based on the Gumbel model are evaluated based on univariate logistic regression D-efficiencies; conversely, designs derived from the univariate logistic regression model are evaluated with respect to the Gumbel optimality criteria. Further practical considerations motivate an exploration of designs providing a maximum compromise between the three Gumbel-based criteria D, Q and T. Finally, 5-point designs which can be generated by fitted equations are proposed as a practical option for experimental use. Ph. D.

Abstract:

The tensile behavior of two ceramic matrix composites (CMC's) was observed. The materials of interest in this study were a glass-ceramic matrix composite (GCMC) reinforced with Nicalon fibers and a BlackglasTM composite also reinforced with Nicalon fibers. Both had a symmetric cross-ply layup. Initial observations of the composites showed significant porosity and some cracking in the Blackglasâ ¢ samples. The GCMC samples showed considerably less damage. From the observed tensile behavior of the cross-ply composites, a 'back-out' factor for determining the 0Â° ply data of the composite was calculated using Classical Lamination Theory (CLT). The predicted behavior of the 0Â° ply was then compared to actual data supplied by McDonnell Douglas Corporation. While the Blackglasâ ¢ material showed good correlation, the GCMC did not. Analysis indicates that the applicability of this technique is strongly influenced by the initial microstructure of the composite, i.e., porosity, cracking. Fracture mirror measurements were also observed to determine the in-situ strength of the Nicalon fibers. Resulting characteristic strength and Weibull modulus values combined with measured fiber pullout lengths were then used to determine material parameters such as the ultimate tensile strength, strain to failure, work of pullout, sliding distance at the characteristic strength, and interfacial shear stress. Comparisons of measured and calculated ultimate tensile strengths and strains to failure showed good agreement. This research was sponsored by the Naval Surface Warfare Center (NSWC) in Dahlgren VA.

Abstract:

The purpose of this study was to determine the extent of the direct and indirect influence of previous grades, quality of instruction, motivation, quantity of instruction, and homework on Hispanic-American eighth grade students' academic achievement, while controlling for important background variables (family background, student's English proficiency, and gender). Few researchers have examined both direct and indirect effects of school learning variables and background influences simultaneously. Path analytic techniques were used to test a model of school learning on Hispanic-American eighth grade students' achievement, while controlling for background variables. The National Education Longitudinal Study of 1988 (NELS:88) was used to test the model. NELS:88 is a large, nationally representative survey of eighth graders developed by the National Center for Education Statistics (NCES). Results indicate that the achievement of Hispanic-American students was strongly influenced by previous grades, motivation, quantity of instruction, and time spent on homework. The most influential background variables were family background and English proficiency, while gender had a small but significant influence, indicating boys doing better than girls on achievement. These results support both the variables tested and the framework derived from school learning theory. Ph. D.

Full text

Abstract:

A crush test fixture for measuring energy absorption of flat plate specimens from an earlier study was redesigned to eliminate the problem of binding of the load transfer platen with the guide posts. Further modifications were to increase the stroke, and combine the two scaled test fixtures into one. This new crush test fixture was shown to produce load displacement histories exhibiting well developed sustained crushing loads over long strokes. An experimental study was conducted on two material systems: AS4/3502 graphite/epoxy, and a hybrid AS4-Kevlar/3502 composite. The effect of geometric scaling of specimen size, the effect of ply-level and sublaminate-Ievel scaling of the stacking sequence of the full scale specimens, and the effect of trigger mechanism on the energy absorption capability were investigated. The new crush test fixture and flat plate specimens produced peak and sustained crushing loads that were lower than obtained with the old crush test fixture. The trigger mechanism used influenced the specific sustained crushing stress (SSCS). The results of this study indicated that to avoid any reduction in the SSCS when scaling from the 1/2 scale to full scale specimen size, the sublaminate-level scaling approach should be used, in agreement with experiments on tubes. The use of Kevlar in place of the graphite 45Â° plies was not as effective a means for supporting and containing the 0Â° graphite plies for crushing of flat plates and resulted in a drop in the SSCS. This result did not correlate with that obtained for tubes. Master of Science

Abstract:

An on-line, passive method for monitoring the moderator temperature coefficient (MTC) in a pressurized water reactor is described and compared to an analytical model. The method correlates fluctuations in the neutron flux with fluctuations in the coolant temperature. Results show that the frequency response function between the in-core neutron flux and thermocouple signals is proportional to the MTC and can be used to monitor changes in the MTC throughout the fuel cycle. An analytical model is also formulated and used to investigate how the neutron flux and coolant temperature fluctuations are related and change in the axial core direction. The analytical model results agree reasonably well with the experimental results. Ph. D.

Abstract:

The membership and participation within Indianapolis Challenge (I-Challenge) has increased significantly over the past year through diversification of both members and organizations. We have developed into a well balanced countywide-represented coalition. This local action plan for the Indianapolis Challenge represented a culmination of efforts and support of the group by major institutions within Marion County. Groups offering support include the following: the Mayor's Office, the State Prosecutor's Office, the Community Service council, the united Way of Central Indiana, Marion County Justice Agency, the Greater Indianapolis Council on Alcoholism and Fairbanks Hospital. Through their research, the Funding Committee, in conjunction with the Planning and Development Committee, were able to make known the needs of the community. One major finding is that there is a moderate effort of coordination taking place in Marion County. Many of the major institutions have acquiesced in the I-Challenge mission by necessity; I-Challenge reviews grants to ensure consistency with the local comprehensive plan for the Department of Mental Health and the Department of Justice substance abuse funds. The data from Marion County is insufficient and agencies have trouble addressing the needs of the community. This is particularly true of those agencies depending on public monies and whose primary mission is to serve the poor. I-Challenge is developing a county-wide strategic plan which will determine the actions necessary to meet the needs of the city. Master of Science in Education
