Data were collected on 24 traits to characterize and classify 35 white floury corn (Zea mays L.) landraces collected on native reserves in Ontario. Several landrace x landrace and landrace x inbred crosses were evaluated. Test crosses were made to determine whether the landraces carry the floury-l (fl$ sb1$) allele. Most traits examined exhibited considerable variation among the landraces. Variation was also observed within many of the landraces for ear and cob colour, for endosperm texture and row number. The landraces were grouped into 10 clusters by centroid clustering analysis. Significant

The design of core/shell nanoparticles is of great interest for a wide range of applications. The primary focus of this dissertation is on the design and optimization of two synthetic routes. The first one is an aqueous reduction method using sodium borohydride and sodium citrate. This method was extended to design two types of core/shell nanoparticles, both of which have many applications in bio-sensing, magnetic resonance imaging, and magnetically guided SERS for the identification of environmental threats. The first, Fe/Ag core/shell nanoparticles were designed using a novel one-pot method

Four embryo-specific sequences and one constitutive sequence were characterized further by RNA blot hybridization and DNA sequence determination.

Synthesis of water soluble carboxylate-terminated Fe4S4-core was carried out. Convergent method was chosen to build three generations of dendrons. Several synthetic schemes were explored. The syntheses were conducted with 4,4-bis(hydroxyphenyl)penthanol as a repeat unit and N,N-dimethyl thiocarbamate and methyl ester or methoxy-methyl as protecting groups. The conditions for deprotection and ligand exchange have been proposed. 1H, 13C and MALDI-MS were used to characterize synthesized molecules.

Abstract:

Regeneration is a process that renews damaged or lost cells, tissues, or even of entire body structures, and is a phenomenon which is widespread in the animal kingdom. Urodeles such as newts and salamanders have a remarkable regeneration ability. They can regenerate organs such as gills, lower jaws, retina, appendages like fore- and hind limbs, and also the tail including the spinal cord. The regeneration process requires the use of resident stem cells or somatic cells, which have to be reprogrammed. In both cases the reprogrammed cells are less differentiated, meaning the cell would have the

Abstract:

Spinal cord injury (SCI) results in a well-orchestrated inflammatory response which causes secondary tissue damage. Activated macrophages contribute to this cytotoxic response, which includes damage to neurons, glia and myelin, and tissue loss that worsens functional outcomes after SCI. However, activated macrophages in the spinal cord under other conditions are not cytotoxic, such as after intraspinal injection of lysophosphatidylcholine (LPC), a potent demyelinating agent. Recovery from SCI may be optimized by reducing the detrimental effects of macrophages while promoting their beneficial o

Tableau d'honneur de la Faculté des études supérieures et postdorales, 2015-2016<br>Le but de ce travail est de produire et de caractériser des structures sandwich à trois couches asymétriques avec ou sans cœur moussé. Pour ce faire, le travail est divisé en deux sections. Dans la première partie, l'effet de la variation des quantités d'agent de couplage et de fibres sont étudiés. La microscopie et la caractérisation mécanique sont utilisées pour évaluer l'effet du polyéthylène greffé d’anhydride maléique (MAPE) sur l'amélioration de la compatibilité entre les fibres de chanvre et le polyéthyl

Tese de mestrado, Química (Química) Universidade de Lisboa, Faculdade de Ciências, 2017<br>Cork is the outer bark of the Mediterranean tree Quercus suber L., and it is used in several industries due to aesthetic look, thermal and sound isolation capacities, although one of the main application is the production of cork stoppers. The cork, after being cleaned and grinded, is boiled and compressed (simultaneously), in order to agglutinate using the endogenous resin. Afterwards, the block is cut with the necessary dimensions. Cork sub-products (CKSP) are generated in the cork processing industry,

Abstract:

This document will review the mechanical tests that were conducted in order to evaluate and identify an optimization threshold for the relative mixtures between standardized polymers and cork. Polyethylene, Polycarbonate and ABS were mixed with varying percentages of cork grains to provide insight into the applicability of utilizing cork as a sustainable alternative in the helmet’s outer shell without statistically significant deterioration of mechanical resistance. This study was conducted to investigate the usage of a composite material composed by a mixture of polymer with cork, for helmet
