Molecular Evolution of Major Epidermal Structure Genes and an Integrative Transcriptome Analysis of Chicken Epidermal Embryogenesis
Αlpha (α) and beta (β) keratins are the major structural proteins found in vertebrate epidermis and the β-keratins are only found in reptiles and birds. With the recent published 48 avian genomes, we searched and studied the molecular evolution of these gene families. We discovered that the expansion and contraction o…

The effect of mechanical stimulation on PEG-encapsulated mesenchymal stem cells
The Effect of Mechanical Stimulation on PEG-Encapsulated Mesenchymal Stem Cells By: BROOKE MCCLARREN Thesis Advisor: Dr. Ronke Olabisi Human mesenchymal stem cells (hMSCs) are multipotent cells capable of differentiating into any mesenchymal tissue, including bone, cartilage, muscle, and fat. hMSC differentiation can…
Optical Modeling and Analysis of Disordered Plasmonic Nanoparticle Ensembles
Plasmonic nanoparticle synthesis provids a facile and cost-effective bottom-up solution to fabrication of nanoscaled structures. With effective packaging methods like embedding into polymer composites and superlattice assemblies, the chemically synthesized nanoparticles are promising candidates for functional devices.…

Clústeres metálicos como almacenadores de hidrógeno : transformación isoeléctrica de los sistemas EnAl4-nH7+n- (E=Be, Mg, Ca, Sr y Ba; n=1-4)
En este trabajo de investigacion se propone el estudio teorico de nuevos hidruros metalicos disenados o generados a traves de transformaciones o modificaciones estrategicas de una especie altamente estable; especificamente para este trabajo fue el cluster atomico Al4H7- reportada por Castleman y colaboradores. Los dif…
Application of nanotechnology in mechanical engineering
New technological processes of hardening using nanotechnology have been developed, tested and used in the manufacture. In this case, an integrated approach is used in the study, which included constructive solutions at hardening, application of nano- and micro-sized coatings, the choice of material and processing tech…
Avaliação do desempenho de solventes não-halogenados na extração do poli(3-hidroxibutirato) a partir de Bacillus megaterium
Polihidroxialcanoatos (PHA) são polímeros sintetizados por diferentes bactérias, que têm despertado grande interesse industrial por suas características de biodegradabilidade e biocompatibilidade, fundamental para aplicações na área médica. Dentre o grande grupo de PHA, o polihidroxibutirato P(3HB) é o mais estudado d…
Less material / More intelligence
A small excursus of designing in a post modern vision, in order to postulate a new Ecology of thought. This paper investigates all the “diverse sensibilities” that in marble design have postulated an essential thought, interpreting the use of “less material” as an occasion for both an aesthetic and a functional resear…
Assessment of hiPSC derived cardiomyocytes maturation in extended culture by analysis of alternative splicing expression patterns
A patologia cardiovascular é um dos maiores problemas de saúde pública e uma das principais causas de morte a nível mundial. Apesar de o impacto socioeconómico destas patologias ser tão demarcado, e ser previsto que a incidência das mesmas venha a aumentar drasticamente nos próximos anos, os mecanismos celulares e mol…
Effects of the Internal Magnetic Field on the Magneto-Mechanical Properties of Magnetic Shape Memory Alloys
Shape memory alloys are a class of functional material which recover from large strains without permanent deformation. The strain is accommodated by the displacement of twin boundaries in the martensite phase. The shape memory alloy Ni-Mn-Ga is also ferromagnetic. Ni-Mn-Ga preferentially magnetizes along a certain cry…
Investigation into a high reliability micro-grid for a nuclear facility emergency power supply

Linking process-structure-property relationships: Modeling and optimization in thin film morphologies
With the rise of the plastic electronics, there has been a renewed interest in microstructure-sensitive design. Since processing conditions are known to heavily influence the microstructure, identifying optimal fabrication conditions is a crucial step towards the development of high-performance devices. A key componen…
Ruolo di K, Ca e Mg nel disseccamento del rachide

Electronic Properties of Methyl-Terminated Germanane and Hydrogen-terminatedGermanane
Two-dimensional (2D) materials have attracted much attention in the last decade.The discovery of graphene has shown that such single-atom-layer sheets exfoliated from crystalline are fundamentally different from their parent materials.Since almost all atoms are exposed to the surface, the covalent surface termination…
Using experimental patternmaking and digital technologies to design and create a self-help childrenswear ensemble
Little research exists for use of experimental patternmaking methods to create apparel in conjunction with other design techniques, for markets outside of adult apparel, or around a specific inspiration. This research explored through practice the outcome when the planar flux experimental patternmaking technique was u…
Tuning the gel structure with temperature controlled sequential gelation; Relating mechanical properties and structure in microgel self-assemblies
Control over the properties of amorphous materials requires thorough understanding of the relation between structure and elasticity. Colloidal gels have been used as model system to study morphology and mechanical properties, but correlation between these features has not been addressed. No previous work has exploited…

Investigating the Effect of Chemical Structure on the Physical Properties of Vapor-Deposited Organic and Inorganic Glasses
The existence of nanometer-sized amorphous material (glasses) is ubiquitous and plays a crucial role in the rapid growing technology community. Physical vapor deposition is commonly used to produce nano-scaled glasses, with the assumption that thin film properties will resemble those of the bulk. However, intermolecul…
