Abstract:
In recent years, in rural geographic studies, the topic of multifunctions of rural areas has been gaining increasing interest, especially in China, which, as an agricultural power, is undergoing new urbanization and rural revitalization. As far as China is concerned, to classify administrative villages from the perspective of their functions will contribute to scientifically guiding the configuration of urban-rural factors in terms of different regions and villages multifunctional types. This paper takes 3042 administrative villages of Tai’an city of Shandong province in eastern China as its basic study units and establishes a mapping system between land use types and rural territorial sub-functions, identifies their multifunctional types via cluster analysis, quantitatively analyzes their influencing factors with multivariate logistic regression, and summarizes their spatial structure characteristics. The results show that: 3042 administrative villages in Tai’an city can be functionally classified into seven types. The village multifunctional types are jointly decided by cities and natural production conditions. The distribution of all types of villages shows a “non-agricultural production to agricultural production” outward expansion structure. Our study can expand the research contents and methods of rural territorial multifunction.

Abstract:
Suitable applications of smart structures for multifunctional spaces are going to be found by this paper. Logical argumentation research method is applied to identify a special smart structure which its features match to architectural requirements of multifunctional spaces. Hence, the smartness of architectural structures has two distinct scales: nanoscale and real scale, the application of these structures is based on two scales. Nanoscale smart structures have the capabilities which differ from real-scale smart structures. The analysis of features of multifunctional spaces shows that these kinds of spaces require structures which are smart both in nanoscale and real scale. As a result, combined-scale smart structures are recommended for multifunctional spaces.

Abstract:
The minimum cost is an important aspect of the spacecraft design. A proposed approach is the multifunctional structure technology, which fully integrates subassemblies and performs both structural and other functions for spacecraft. By combining the structural and functional subsystems into a single unit, the mass and volume savings can be realized. In order to investigate the dynamical properties of the multifunctional structure, which contains viscoelastic components, sine-sweep tests and random vibrations are carried out in present paper. The experimental results show that the multifunctional structure could survive the vibration environment. The first resonance frequency decreases with increment of the testing levels, and the base frequency of the multifunctional structure is larger than 100 Hz for all tested loading cases, meeting the frequency requirement for most spacecraft platforms. The multifunctional structure in this paper has successfully combined the structural and battery function, indicating potential for future lightweight and cost-saving spacecraft application.

Abstract:
An original low-power low-voltage multifunctional structure with improved performances will be further presented, allowing to implement (with minor changes in the design) four important functions: the signal gain with theoretical null distortions, voltage multiplying with very good linearity and simulation of a perfect linear resistor with both positive and negative equivalent resistance. The linearity will be strongly increased by implementing original techniques, while the silicon occupied area per function will be reduced as a result of the circuit multifunctionality. The structure is implemented in 0.35 μm CMOS technology and is supplied at ±3 V. The circuit presents a very good linearity (THD < 0.1% for differential amplifier and active resistors and THD < 0.15% for multiplier), correlated with an extended range of the input voltage (-1.5 V < v1 - v2 < 1.5 V ). The tuning range of the active resistor is about 100kΩ – 1.5MΩ. The second-order effects are also considered, being proposed an original technique based on an anti-parallel connection for compensating the linearity degradation introduced by these effects.

Abstract:
EDPDB is a Fortran program that simplifies the analysis of protein structure and makes it easy to extract various types of geometrical and biologically relevant information for the molecule both in isolation as well as in its crystallographic context. EDPDB offers a large set of functions by which the user can evaluate, select and manipulate the coordinates of protein structures. Types of calculation available include the determination of solvent accessibility, bond lengths and torsion angles, determination of the van der Waals volume of a group of atoms, determination of the best-fit plane through a set of points, evaluation of crystal contacts between a molecule in a crystal and all symmetry-related molecules, and the determination of `hinge-bending' motion between protein domains. It is also possible to compare different structures, to perform coordinate manipulations and to edit coordinate files. The program augments the graphic analysis of protein structure by allowing the user to construct a simple set of commands that will rapidly screen an entire structure. It may also make special purpose analyses feasible without complicated programming.

Abstract:
Multifunctional material systems are systems that contain individual materials or components which are capable of performing multiple functions. The combination of functions into single entities allows for system-level benefits that are not possible through the optimization of subsystems independently. Benefits enabled through multifunctional designs include increased system efficiency through mass and or volume savings as well as part count reductions. Fiber reinforced polymer (FRP) composite materials are lightweight, high-strength materials that can be tailored to achieve a unique set of properties. These characteristics make composites ideal materials for multifunctional designs. The current research focuses on the production, optimization, and characterization of a multifunctional fuel cell system. This product combines fuel cell technology with composite materials technology to achieve a design that produces electrical power while also providing specific load carrying capability. The study investigates new system designs and new processing techniques, including vacuum assisted resin transfer molding (VARTM) and pultrusion. A metric which allows for the characterization of multifunctional fuel cell systems is developed and applied to three fuel cell designs. This metric uses Frostigâ s Higher Order Theory to analyze the mechanical behavior of the cells while the electrical performance of each device is based on its specific power output. For the cells investigated here, multifunctional efficiencies between 22% and 69% are achieved. The multifunctional efficiency is highly dependent on the transverse pressure applied to the fuel cell components, as this pressure determines ohmic resistances, mass transfer properties, and sealing abilities of the systems. The mechanical pressures at the GDL/Polar Plate interface of a model fuel cell system are explored via experiments with pressure-sensitive film as well as FEA studies, and an optimum structural pressure of approximately 200 psi is identified. Additionally, the effects that concentrated, bending loads have on the electrochemical performance of a model multifunctional cell are explored. The results indicate that one must give generous consideration to the out of plane loads which the fuel cell system will be subjected to (both inherent, structural loads resulting from processing conditions and external, applied loads encountered during operation) in order to achieve optimal multifunctional efficiency.

Abstract:
A multifunctional structural polymer electrolyte membrane (PEM) fuel cell was designed, developed and manufactured. The structural fuel cell was designed to represent the rear rib section of an aircraft wing. Custom membrane electrode assemblies (MEA s) were manufactured in house. Each MEA had an active area of 25cm2.The platinum loading on each electrode (anode and cathode) was 0.5mg/cm2. Sandwiched between the electrodes was a Nafion 212 electrolyte membrane. Additional components of the structural fuel included metallic bipolar plates and end plates. Initially all the components were manufactured from aluminium in order for the structural fuel cell to closely represent an aircraft wing rib. However due to corrosion problems the bipolar plate had to be manufactured from marine grade 361L stainless steel with a protective coating system. A number of different protective coating systems were tried with wood nickel strike, followed by a 5μm intermediate coat of silver and a 2μm gold top coat being the most successful. Full fuel cell experimental setup was developed which included balance of plant, data acquisition and control unit, and a mechanical loading assembly. Loads were applied to the structural fuel cells tip to achieve a static deflection of ±7mm and dynamic deflections of ±3mm, ±5mm, and ±7mm. Static and dynamic torsion induced 1° to 5° of twist to the structural fuel cell tip. Polarisation curves were produced for each load case. Finite element analysis was used to determine the structural fuel cell displacement, and stress/strain over the range of mechanical loads. The structural fuel cells peak power performance dropped 3.9% from 5.5 watts to 5.3 watts during static bending and 2% from 6.2 watts to 6.1 watts during static torsion. During dynamic bending (2000 cycles) the structural fuel cell peak power performance dropped 11% from 6.7 watts to 6 watts (3mm deflection at 190N), 23% from 6.3 watts to 4.8 watts (5mm deflection at 270N), and 41% from 7.2 watts to 5 watts (7mm deflection at 350N). During dynamic torsion (2000 cycles) the structural fuel cell peak power performance dropped 16% from 6 watts to 5.1 watt (3° of torsional loading), and 30% from 6.4 watts to 4.3 watts (5° of torsional loading). The simulated (finite element modelling) displacement of -6.6mm (At maximum bending load of 364.95N) was within 9% of the actual measured displacement of -7.2mm at 364.95N. Furthermore the majority of the simulated strain values were within 10% of the actual measured strain for the structural fuel cell.

Abstract:
This thesis seeks to augment the understanding of gelled micro-particulate suspensions known as sheared/fluid gels, by investigating the use of dairy proteins (whey, WPI) as the gelling material. The research used a microstructural approach to probe the underlying design principles governing the formation, and subsequent material properties of WPI microgel systems. The work initially focused on preparing suspensions through both thermal and cold-set approaches. By controlling two key processing parameters: shear and gelling rate, it was shown that a range of suspension properties could be produced. In both cases, it was demonstrated that structural characteristics could be controlled, for tailored rheologies. The shear technology was then applied to a more complex system of oil and whey protein, resulting in the formation of microcapsules; as the WPI gelled around the oil droplets in a core-shell model. Again, controllable structural properties were obtained, however, the lipophilic core provided a reservoir for potential delivery. This multi-functional formulation was then investigated under gastro-intestinal conditions, highlighting controllable release as a function of the type of oil used in production. Therefore, the potential use of WPI/WPI-oil micro-particles have been presented as a multi-functional composite for both structure and delivery within food ingredients.

Abstract:
Dan Beaty (1937-2002) was a prolific composer, pianist, researcher, educator, and writer. His large compositional output included chamber works, choral works, songs, orchestral pieces, electronic music, and keyboard works. Beaty was well versed in traditional Western music as well as the more avant-garde and perplexing idioms of the twentieth century. Beaty's compositions reflect the many fascinating, if not always popular, musical trends of his time. His music encompasses styles from serial to jazz, shows compositional influences from Arnold Schoenberg to Indonesian music, and demonstrates thought-provoking and highly intellectual craftsmanship. This document explores several of Beaty's songs through a discussion of the composer's life and compositional process. Songs included in this document are Three Weeks Songs, October, November, A Sappho Lyric, Love Song, That Night When Joy Began, and War Lyrics. This document was written to accompany the author's DMA Lecture-Recital at the University of North Texas. Unfortunately, Beaty's vocal music was never published and is mostly unknown. One goal of the project was to initiate interest in Beaty's songs. Through this document, Lecture-Recital, and additional performances, considerable strides have been made to bring Beaty's songs to new audiences throughout the United States. In addition, the author has received permission from the Beaty family to publish Dan Beaty's songs.

Abstract:
Les textiles jouent un rôle important dans notre vie quotidienne. La plupart des fibres textiles et des tissus sont fabriqués à partir de polymères à base de pétrole, des matériaux inflammables et potentiellement dangereux. Afin de conférer le caractère ignifuge aux fibres textiles; entre autres, les composés halogénés sont plus efficaces et largement utilisés pour améliorer le comportement ignifuge des matières textiles. Cependant, en raison de la toxicité des composés halogénés et de l'épuisement progressif des ressources pétrolières, les communautés scientifiques et industrielles sont obligées de trouver des solutions alternatives. Par conséquent, on s’intéresse de plus en plus aux ressources durables, en particulier au développement de systèmes ignifugeants fabriqués à partir de ressources biologiques et respectueux de l’environnement non halogénés. Dans le contexte de l’utilisation de ressources biologiques, une attention particulière a été appelée pour la biomasse. Après la cellulose, la lignine est le deuxième polymère de biomasse le plus abondant et le principal à base d'unités aromatiques. En particulier, la lignine est avantageuse car c’est un coproduit des industries de la pâte à papier et de la fabrication du papier et non une ressource qui nécessite une production spécifique. En fait, sa structure chimique hautement aromatique permet d’améliorer différentes propriétés fonctionnelles telles que la résistance aux UV, l’antioxydant et l’ignifugation des polymères. Récemment, la lignine a fait l’objet d’une grande attention en tant qu’additif retardateur de flamme d'origine biologique en raison de son aptitude élevée à la formation de carbone après la décomposition thermique. Cette capacité de formation de carbone de la lignine en fait un candidat de choix comme source de carbone pour un système intumescent avec un autre additif ignifuge. Lors du chauffage, les matériaux intumescents ignifuges (FR) forment une couche carbonisée cellulaire expansée; agissant comme une barrière physique contre le transfert de chaleur et de masse, qui protège le matériau sous-jacent de l'action du flux de chaleur et de la flamme.Au meilleur de nos connaissances, aucune étude n'a été publiée concernant l'introduction de la lignine en tant que source de carbone dans les structures textiles pour leur conférer des propriétés ignifugeantes. Par conséquent, dans cette étude, la lignine a été introduite dans la structure textile lors de la composition. Cette thèse porte sur le développement de la structure textile ignifuge entièrement biosourcée. Pour atteindre cet objectif, l'approche en plusieurs étapes est adoptée. Dans une première étape, la matrice polymère biosourcée a été sélectionnée pour produire la structure textile et la méthode d’incorporation de la lignine a été étudiée et optimisée. Ensuite, les propriétés ignifuges apportées par la lignine ont été caractérisées et améliorées en ajoutant un additif ignifuge dans les formulations (par exemple, utilisation de sources acides pour développer un système intumescent pouvant améliorer la résistance des textiles au feu). Dans la deuxième phase du projet, la lignine a été combinée à la source d'acide d'origine biologique pour développer une nouvelle génération de structures durables (100% biosourcées) destinées aux marchés du textile. La principale avancée technologique consiste à utiliser et à combiner différents composants biosourcés utilisés dans d'autres industries, telles que l'industrie du plastique, afin de développer des solutions textiles
It has been chosen to study valorization of low-cost industrial lignin as additive in designing the flame retardant (FR) system for polyamide 11 (PA) to develop biobased textile structure. The main focus of this thesis work is to consider lignin as carbon source and introduce in a textile structure in combination with phosphinate salt (FR agent). In the primary study, chemically different industrial lignins were incorporated in PA by extrusion to investigate the charring and fire retardant behaviour of the prepared binary blends. In addition, the introduction of sulphonated lignins significantly reduced the peak of the heat release rate (PHRR) and of the total heat release (THR), and a noticeable increase of the char residue was observed after forced combustion test. In the next approach, lignin was exploited as carbon source in combination with commercially available phosphinate FR (i.e., ZnP and AlP). To achieve this objective, a preliminary study carried out with laboratory grade lignin (LS) combined with ZnP to investigate the thermal stability and fire performance as well as the possible synergy between lignin and ZnP and with the polymer matrix. The results obtained in this study permitted to continue further, the practical implementation of lignin and multifilament production. In the next step, flame retarded blends were developed with direct addition of low-cost industrial lignins (LL and DL) with phosphinate FR. For the systematic understanding, various FR formulations were developed by varying the lignin and FR loading and characterized. Thermal decomposition analysis showed that the presence of lignin decreases the initial decomposition temperature (T5%) due to the decomposition of lignin which starts at a lower temperature region with the evolution of less thermally stable compounds and the maximum decomposition temperature (Tmax) shifts to higher temperature region, at this stage the formation of phenolic, carbonyls, hydrocarbons and CO2 along with phosphinate compounds occurs. Meanwhile, in the condensed phase thermally stable aromatic charred layer is formed because of lignin decomposition and phosphate compounds formation due to the presence of phosphinate metal salt. A higher amount of char residue is obtained when LL combined with ZnP/AlP as compared to the DL and ZnP/AlP blends. It is assumed that, during decomposition of LL, the sulfonate compounds release SO2 and transformed into thermally stable Na2SO4, hence giving rise to the stable char residue. The fire properties were assessed by cone calorimeter tests revealed the combination of lignin and phosphinate FR significantly reduced the PHRR and other fire-related parameters due to the formation of a protective char layer. The presence of lignin not only improve fire retardancy but also reduced the evolution of carbon monoxide (CO). More enhanced fire retardant properties were obtained with LL and ZnP/AlP combination reaches to 10 wt% in ternary blends, which not only promotes char formation but also confer the stability to char in the condensed phase. Furthermore, the most enhanced forced combustion results were obtained with LL and AlP (in particular, PA80-LL10-AlP10). Multifilament yarns were successfully produced for PA-DL-ZnP and PA-LL-ZnP combinations. However, the blends of AlP with lignin were not spinnable because of low compatibility and dispersion level of AlP in the polymer. Optical microscopy and tensile tests were performed to study the physical properties of multifilaments. A double layer (interlock structure) knitted fabrics were developed to evaluate fire behaviour analysis on fabric samples

Abstract:
Abstract Multifunctional enzyme type 2 (MFE-2) catalyses the second and the third reactions in the eukaryotic peroxisomal β-oxidation cycle, which degrades fatty acids by removing a two-carbon unit per each cycle. In addition to the 2-enoyl-CoA hydratase 2 and (3R)-hydroxyacyl-CoA dehydrogenase activities, mammalian MFE-2 has also a sterol carrier protein type 2-like (SCP-2L) domain. In contrast, yeast MFE-2 has two (3R)-hydroxyacyl-CoA dehydrogenases, one 2-enoyl-CoA hydratase 2 and no SCP-2L domain. The physiological roles of yeast (3R)-hydroxyacyl-CoA dehydrogenases (A and B) were tested by inactivating them in turn by site-directed mutagenesis and testing the complementation of Saccharomyces cerevisiae fox-2 cells (devoid of endogenous MFE-2) with mutated variants of Sc MFE-2. Growth rates were lower for fox-2 cells expressing only a single functional domain than for those expressing the Sc MFE-2. Kinetic studies with purified Candida tropicalis MFE-2 and its mutated variants show that dehydrogenase A catalyzes the reaction more efficiently with the medium- and long-chain substrates than dehydrogenase B, which in turn is the only one active with the short chain fatty acids. The structural basis of the substrate specificity difference of these two dehydrogenases was solved by X-ray crystallography together with docking studies. Protein engineering was used to produce a stabile, homogenous recombinant protein of C. tropicalis dehydrogenases in one polypeptide. The heterodimeric structure contains the typical fold of the short-chain alcohol dehydrogenase/reductase (SDR) family. Docking studies suggest that dehydrogenase A binds medium chain-length substrates as bended, whereas short chain substrates are dislocated, because they do not reach the hydrophobic contacts needed for anchoring the substrate to the active site, but are instead attracted by L44. Dehydrogenase B has a more shallow binding pocket and thus locates the short chain-length substrates correctly for catalysis. Thus the data provide clues for structural basis of the different substrate specificities. The molecular basis of the patient mutations of MFE-2 (DBP deficiency) was studied using the recently solved crystal structures of rat (3R)-hydroxyacyl-CoA dehydrogenase, human 2-enoyl-CoA hydratase and SCP-2L. The predicted effect of the mutations on protein structure could in several cases be explained, and these data supported the conclusion that a genotype-phenotype correlation exists for DBP deficiency.

Abstract:
The type I R-M enzyme EcoR124I is a multifunctional, multisubunit molecular motor with the ability to self-assemble. In the presence of hydrophobic compounds, subunit disassembly has been observed leading to the possibility of using the enzyme as a nanoactuator in toxicity biosensors. A better understanding of single molecule interactions between the subunits has been investigated using atomic force microscopy (AFM), a powerful tool for measuring forces and dynamics between single molecules with a picoNewton sensitivity. AFM imaging of DNA fragments with a single recognition binding site for EcoR124I positioned in the middle or at 1/3 of the length of DNA, was used to study the assembled holoenzyme. Reproducible DNA imaging was investigated using divalent cations (Mg2+, Ca2+, Ni2+). The presence of only one EcoR124I holoenzyme bound to DNA was observed, confirming the specificity of binding. Molecular volume (Vm) measurements were used to identify subunits and complexes. The effect of ATP analogues (ATP-γ-S and AMP-pnp) on enzyme stability was also investigated. The addition of ATP, although not novel, confirmed the enzyme activity by showing the ability of the enzyme to translocate. Biotin-avidin interactions were studied using AFM force curves as a model to probe the novel HsdR-MTase system. AFM tips were functionalised using both glutaraldehyde and a PEG linker. In the former, many multiple event force curves were seen, although the final “pull-off” event yielded information on single-molecule or near single-molecule interactions: a single biotin-avidin interaction at 56 ± 13 pN was measured, with further periodic force maxima at 98 ± 15 and 161 ± 3 pN (two and three interactions, respectively). The use of a PEG linker allowed more sensitive measurements to be made, with a single biotin-avidin interaction at 47 ± 9.5 pN and, again, periodic maxima were seen at 93 ± 7 and 143 ± 4 pN. The PEG linker method allowed more single molecules interactions to be measured (ca. 70% of analysed forcedistance curves). Forces between a GST-HsdR(PrrI) motor subunit attached to an AFM tip using a PEG linker and MTase on poly-L-lysine pre-treated mica were studied using dynamic force spectroscopy (DFS). A single barrier in the energy landscape of the complex was found in the dissociation pathway (xdiss) to be located 13.5 Å from the bound state. The value kdiss for the GST-HsdR(PrrI)-MTase complex was calculated to be 0.16 s-1 and the lifetime t(0) of the GST-HsdR(PrrI)-MTase bond was found to be 6.25 s. GST – anti GST antibody interactions and HsdR – anti-GST antibody interactions suggest that forces measured between HsdR and MTase were realistic for the GSTHsdR(PrrI)-MTase complex.

A small space based telescope is being designed by the Charles Stark Draper Laboratory, Inc. in conjunction with MIT. The design goal of this project is to use existing technology to gather ground data from low earth orbit at a minimal cost. A structure was constructed at MIT that allows the satellite to survive launch loads and maintains the optical stability of the satellite. The structure is a double hull design constructed of AS4/3501-6 graphite epoxy with a zero coefficient of thermal expansion lay-up to prevent defocussing of the optics due to thermal loading. The overall design goal at MIT is to construct a space worthy structure. This thesis includes the preliminary design of the inner structure that houses the optics for the telescope. Design of the outer structure, the connections between the inner and the outer structure and detailed design of the inner structure are not included in this work. The analytical techniques used in this project included thermal analyses of structures in various earth orbits, determination of structural requirements from optical performance calculations, designing of near zero Coefficient of Thermal Expansion (CTE) laminates, consideration of manufacturing and material variations in design, strength analysis of composite laminates, and determination of vibration modes and associated frequencies of tubular structures with anisotropic sandwich construction. Experimental work included the building of co-cured honeycomb panels, curved panels, and tubular sections to verify the structure as designed was manufacturable. These efforts culminated in the production of a space-worthy component. Testing was preformed to verify the analysis and design. Testing included flatwise tension testing to verify integrity of the honeycomb bonding, tensile testing to verify stiffness calculations and experimentally determine the failure load for the desired lay-up, and testing to verify the CTE was within acceptable bounds to prevent the optics from defocussing.

Abstract:
This research focuses on elucidating on the processing-structure-property relationship in hierarchically-structured polymer composites that are being developed for multifunctional structures. This is accomplished through characterization of the transition in mechanical behavior that occurs across length scales and compositions by: (a) development of model hierarchically-structured composite materials using a combination of model nanoscale and microscale ingredients (carbon nanofibers (CNFs) and carbon microfibers (CMFs)) reinforcing a High Impact Polystyrene (HIPS) thermoplastic polymer that can be extruded or solvent processed, (b) characterization and modeling of the transition compositions in the polymer nanocomposites through melt rheology, and (c) the effect of the CNF on the dynamic compressive behavior of CMF-reinforced polymer composites.

Abstract:
Abstract Natural frequencies and damping ratios of doubly clamped and cantilever alviminum pipes filled with high pressure gas (Argon or, Xenon fuel) or high pressure liquid (Water) were measured using shaker and hammer test techniques. The results show that natural frequencies and damping are a little sensitive to the pipe internal pressure. The damping ratios were slightly affected by the pipe filler material. However, the natural frequencies of the pipe filled with water was lower compared to those filled with Argon and Xenon fuel. The damping ratios measured using a shaker were almost two orders of magnitude lower than those measured using hammer tests. This could be due to the extra damping induced to the system from the magnetic field of the shaker.
