International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Aircraft Research and Development Unit (ARDU) of the Royal Australian Air Force (RAAF) is the only agency in Australia that performs the full spectrum of military flight testing and is the new custodian of the instrumented weapons range at Woomera. Receiving early attention will be the upgrade and integration of ARDU's telemetry systems with the meteorological and tracking data acquisition capabilities at Woomera to minimize overhead and data turnaround time. To achieve these goals, maximum modularity, extensibility, and product interoperability is being sought in the proposed architecture of all the systems that will need to cooperate on the forecast test programmes. These goals are also driven by the need to be responsive to a wide variety of tasks which presently include structural flight testing of fighter and training aircraft, weapons systems performance evaluation on a variety of combatant aircraft, and a host of other tasks associated with all fixed and rotary wing aircraft in the Army and Air Force inventory. Of all these tasks however, ARDU sees that responsiveness to future testing of F-111Cs fitted with unique Digital Flight Control Systems along with USAF standard F-111Gs may place the most significant demands on data handling —particularly in regard to providing an avionics bus diagnostic capability when performing Operational Flight Programme (OFP) changes to the mission computers. With the timely assistance and advice of Loral Test & Information Systems, who has long-term experience in supporting USAF F-111 test programmes, ARDU is confident of making wise design decisions that will provide the desired flexibility and, at the same time, minimize life-cycle costs by ensuring compliance with the appropriate telemetry and open systems standards. As well, via cooperative agreements with the USAF, the potential exists to acquire proven software products without needing to fund the development costs already absorbed by the USAF. This paper presents ARDU's perception of future needs, a view by LTIS of how best to meet those needs, and, based on ARDU data, a view of how LTIS' proposal will satisfy the requirement to provide maximum extensibility with minimum life-cycle costs.

Plugged and abandoned well pads throughout the Uintah Basin face reclamation challenges due to factors including a harsh climate, invasive species, and high salt loads. Finding ways to alleviate soil sodicity could improve soil reclamation success. Gypsum, sulfur, activated carbon, and Biochar are being applied to improve soil parameters negatively impacted by sodicity, but the direct impact of these amendments on Uintah Basin soils is still largely unknown. The aim of this study was two-fold. (1) Evaluate the effectiveness of gypsum, sulfuric acid, Biochar, activated carbon, and combinations of these amendments in reducing the impact of soil sodicity of the Desilt and Conglomerate soils by measuring amendment impact on percent dispersion, saturated hydraulic conductivity, crust bulk density, infiltration, and crust formation. (2) Compare a crust bulk density method using ImageJ to the clod wax density method and a modified linear extensibility percent equation to the linear extensibility percent equation to assess whether the novel methods can be used to accurately measure and calculate soil crust bulk density and shrink swell potential while reducing human error and analysis time.

L’auto-assemblage de macromolécules amphiphiles dans des solutions aqueuses est un mécanisme important sous-jacent à de nombreux processus présents dans les organismes vivants. La formation spontanée de structures auto-organisées de phospholipides et de biomacromolécules se produit en raison d'un équilibre délicat entre les forces d'attraction et de répulsion. Ces forces comprennent l'attraction hydrophobe, la liaison hydrogène, les forces de coordination des métaux et la répulsion stérique ou électrostatique. En outre, l'auto-assemblage de molécules amphiphiles synthétiques est largement utilisé dans divers domaines technologiques. Un exemple frappant est celui des surfactants de faible poids moléculaire qui peuvent modifier de manière significative les propriétés des systèmes. Les autres domaines importants dans lesquels les tensioactifs et les macromolécules amphiphiles sont activement utilisés sont la cosmétologie et l'hygiène. Cependant, l'utilisation de structures auto-organisatrices de macromolécules amphiphiles nécessite une étude approfondie et soulève quelques questions pour les chercheurs concernant leur structure, leur comportement sous l'influence de facteurs externes et leur stabilité. L'objectif principal de la thèse était de développer une théorie de champ analytique auto-cohérente de l'auto-organisation dans des solutions de copolymères de déblocage non ioniques linéaires dendritiques et dendritiques doubles dans des solvants sélectifs. Cette théorie nous permet de prédire comment la dendronisation d'un ou des deux blocs affecte les propriétés structurelles et thermodynamiques d'assemblages auto-organisés formés par des copolymères. Il a été démontré que la dendronisation des corona bloc permet d’obtenir les micelles stables de taille relativement petite, mais avec de nombreux groupes terminaux. Cette dernière caractéristique est particulièrement intéressante dans le contexte de la liberation contrôlée, puisque les groupes terminaux exposés à l'environnement peuvent être facilement fonctionnalisés par des groupes de ligands pouvant être ciblés. Ces deux caractéristiques peuvent être obtenues simultanément car la dendronisation des corona bloc réduit le nombre d'agrégation à l'équilibre et les dimensions globales des micelles par rapport aux micelles formées par des molécules de copolymères diblocs linéaires homologues tout en conservant un grand nombre de groupes terminaux par micelle. La dendronisation du bloc insoluble peut être utilisée pour augmenter le nombre d'unités monomères terminales dans le core. Nous avons également démontré que la dendronisation des blocs solubles favorise la formation de micelles sphériques, alors que les gammes de stabilité thermodynamique des micelles cylindriques et des dendrimersomes sont déplacées vers un degré plus élevé de polymérisation des séquences insolubles. Au contraire, la dendronisation du bloc insoluble a l'effet inverse et conduit à un élargissement des gammes de stabilité des polymeres et des micelles cylindriques.Nous avons étudié les effets de l'extensibilité finie dans les brosses polyélectrolytes à chaîne linéaire et à dendron contenant des groupes ioniques. Nous avons développé la théorie analytique des brosses polyélectrolytiques dans l'approximation de Poisson-Boltzmann qui explique explicitement l'extensibilité finie des chaînes de polyélectrolytes formant des brosses. Il a été montré que pour la même série de paramètres de la brosse, la théorie basée sur l’élasticité non linéaire des polyions prédit une épaisseur de la brosse plus faible et une plus grande amplitude du saut de la densité du polymère au bord du pinceau. Les connaissances obtenues fourniront une base rationnelle pour la conception moléculaire de nouveaux copolymères à blocs complexes sur le plan architectural, y compris ceux destinés à des applications médicales. / An important mechanism underlying many processes occurring in living organisms is self-assembly of amphiphilic (macro)molecules in aqueous solutions. Spontaneous formation of self-organized structures of phospholipids and biomacromolecules occurs because of a delicate balance between attraction and repulsion forces. Such forces include hydrophobic attraction, hydrogen bonding, metal coordination forces and steric or electrostatic repulsion.In addition, self-assembly of synthetic amphiphilic molecules is widely used in various technical fields. A striking example are low molecular weight surfactants (small amphiphilic molecules) that can significantly change the properties of systems. Other important areas in which surfactants and amphiphilic macromolecules are actively used are cosmetology and hygiene. However, the use of self-organizing structures of amphiphilic macromolecules requires detailed study and raises a few questions for researchers regarding their structure, behavior under the influence of external factors and their stability.The main goal of the present work was development of the theory of self-assembly of diblock copolymers where one or both of blocks (soluble or/and insoluble) exhibit dendritic branching and established relations between degree of branching of the block(s) and structural properties (size, shape, aggregation number) of the self-assembled aggregates.The major focus of the thesis was on developing an analytical self-consistent field theory of self-organization in solutions of non-ionic linear-dendritic and double-dendritic deblock copolymers in selective solvents. This theory enables us to predict how dendronization of one or both blocks affects structural and thermodynamic properties of self-organized assemblies formed by copolymers. It was demonstrated that dendronisation of the corona blocks allows obtaining the stable micelles of relatively small size, but with many terminal groups.The latter feature is most attractive in the context of controlled delivery, since the exposed to the environment terminal groups can be readily functionalized by targetable ligand groups. Both these features can simultaneously be achieved because dendronization of the corona blocks reduces the equilibrium aggregation number and overall dimensions of micelles compared to micelles formed by homologous linear-linear diblock copolymer molecules while keeping large number of terminal groups per micelle. Dendronization of the insoluble block may be used for increasing of the number of terminal monomer units in the core. Such terminal groups can be further functionalized to be able to interact with active drugs, thereby increasing the loading capacity of the micelle.We have also demonstrated that dendronization of the soluble blocks favors formation of spherical micelles, whereas the ranges of thermodynamic stability of cylindrical wormlike micelles and dendrimersomes are shifted to larger degree of polymerisation of the insoluble blocks. On the contrary, dendronization of the insoluble block has the opposite effect and leads to widening of the stability ranges of polymersomes and cylindrical micelles.We investigated effects of finite extensibility (non-linear elasticity) in linear chain and dendron polyelectrolyte brushes containing ionic groups. We developed the analytical theory of polyelectrolyte brushes within the Poisson-Boltzmann approximation which explicitly accounts for finite extensibility of the brush-forming polyelectrolyte chains. It was shown that for the same set of the brush parameters the theory based on non-linear elasticity of the polyions predicts smaller thickness of the brush and larger magnitude of the jump in polymer density at the edge of the brush.The obtained knowledge will provide a rational background for molecular design of novel architecturally complex block copolymers, including those for medical applications.

The purpose of this research was to study the synthesis and remodeling of extracellular matrix (ECM) by fibroblasts with special emphasis on the culture environment (media composition and initial ECM composition) and the resulting mechanical integrity of the ECM. This was investigated by culturing fibroblasts for 3 weeks in a variety of culture conditions consisting of collagen gels, fibrin gels, or media permissive to the self-production of ECM (Cell-Derived Matrix), and quantifying the mechanics of the resulting ECM. The mechanical characteristics were related to the biochemistry of the resulting ECM, notably in terms of collagen accumulation and collagen fibril diameters. The ultimate tensile strength (UTS) of the collagen gels and fibrin gels at the end of the 3-week period was 168.5 ± 43.1 kPa and 133.2 ± 10.6 kPa, respectively. The ultimate tensile strength of the cell-derived matrices was 223.2 ± 9 kPa, and up to 697.1 ± 36.1 kPa when cultured in a chemically-defined medium that was developed for the rapid growth of matrix in a more defined environment. Normalizing the strength to collagen density resulted in a UTS / Collagen Density in these groups of 6.4 ± 1.9 kPa/mg/cm3, 25.9 ± 2.4 kPa/mg/cm3, 14.5 ± 1.1 kPa/mg/cm3, and 40.0 ± 1.9 kPa/mg/cm3, respectively. Cells were synthetically more active when they produced their own matrix than when they were placed within gels. The resulting matrix was also significantly stronger when it was self-produced than when the cells rearranged the matrix within gels that corresponded to a significantly larger fraction of non-acid and pepsin extractable collagen. These studies indicate that cell-derived matrices have potential both as in vitro wound healing models and as soft connective tissue substitutes.

Tortilla sales are projected to exceed 9.5 billion by 2014. However, currently no wheat cultivars have been identified that possess the intrinsic quality attributes needed for the production of optimum quality tortillas. Tortillas made with refined wheat flour low in dietary fiber (DF) are popular in the United States due to their sensory properties. This study explored the use of wheat lines (WL) possessing variations in high molecular weight glutenin allele sub-units (HMW-GS) for production of tortillas and also investigated the use of corn based resistant starches (RS), type II (RS2) and wheat based RS type IV (RS4) to increase DF in tortillas. Tortillas were made with 0-15 percent RS and 100 percent whole white wheat (WW). Flour protein profiles, dough, and tortilla properties were evaluated to determine the effects of the allelic variations and RS substitution on tortilla quality. Sensory properties of tortillas with RS were determined. Variations in HMW-GS composition significantly affected the protein quality and tortilla properties. Flour from WL possessing allelic combinations (2*, 17+18, 7, 2+12), (1, 17+18, 5+10), (2*, 17, 2+12) and (1, 2*, 17+18, 2+12) had 12.8-13.3 percent protein. These WL had extensible doughs and produced large diameter tortillas with superior (greater than or equal to 3.0) flexibility after 16 days compared to control. However, WL with (17+18 and 5+10) and (2*, 17+7, 5) produced extensible doughs, large, but less flexible, tortillas compared to control. WL with (2*,17+18,5+10) and (1,2*,7+9,5+10) produced smaller diameter tortillas, but with superior flexibility compared to control. RS2, WW, and cross-linked-pre-gelatinized RS4 (FiberRite) produced hard, less-extensible doughs and thinner tortillas compared to control, due to high water absorption. Cross-linked RS4 (Fibersym) dough and tortillas were comparable to control. 15 percent of RS2 and RS4 increase DF in control to 6 and 14 percent respectively, compare to control (2.8 percent DF). WW tortillas were less acceptable than control in appearance, flavor and texture, while tortillas with 15 percent Fibersym had higher overall acceptability than control. RS2 negatively affected dough machinability and tortilla shelf stability. However, 15 percent RS4 improved the DF in refined flour tortillas to meet FDA's "good source of fiber claim," without negatively affecting dough/tortilla quality.
