Abstract:

The present thesis aims to use novel observations as to the behaviour of anaphoric 'one' when under modification in order to explore more acutely the structure of the nominal phrase. There has been decades of disagreement as to the syntactic nature of anaphoric 'one'. This work highlights novel observations about anaphoric 'one' and offers structural analyses for them. Anaphoric 'one' behaves in a markedly distinct way when modified by a prenominal modifier versus when it is modified by a postnominal modifier. Specifically the indefinite article, numerals, and certain quantifiers are able to b

Abstract:

For nearly two decades inclusion compounds (ICs) have been formed by threading polymer chains into the cyclic starches, cyclodextrins (CDs). Non-covalently bonded crystalline ICs have been formed by threading CDs, onto guest nylon-6 (N6) chains. When excess N6 is employed, non-stoichiometric (n-s)-N6-CD-ICs with partially uncovered and dangling N6 chains result. We have been studying the constrained crystallization of the N6 chains dangling from (n-s)-N6-CD-ICs in comparison with bulk N6 samples, as a function of N6 molecular weights, lengths of uncovered N6 chains, and the CD host used.

Abstract:

Although the concept of tensegrity structures was invented in the beginning of the twentieth century, the applications of these structures are limited, partially due to their low stiffness. The stiffness of tensegrities comes from topology, configuration, pre-stress and initial axial element stiffnesses. The first part of the present work is concerned with finding the magnitude of pre-stress. Its role in stiffness of tensegrity structures is to postpone the slackening of cables. A high pre-stress could result in instability of the structure due to buckling and yielding of compressive and tens

CRISPR (clustered regularly interspaced short palindromic repeats)-guided nucleases such as Cas9 remain atop the most exciting biological systems in gene editing and therapeutic potential. The modern adaptation of the Streptococcus pyogenes (Spy) Cas9 machinery for directed DNA editing relies on two major components; a Cas9 protein, and an RNA guide. This study aims at modification of the guide RNA to probe structural requirements and modification tolerance while studying the biochemical properties of the ribonucleoprotein complex.

Genes SMN1 and SNM2 encode SMN protein which is essential for motor neurone survival. In Spinal Muscular Atrophy patients, absence of functional SMN1 means functional SMN protein is encoded by SMN2 alone. SMN2 splicing products do not usually include exon 7, which is required for functional SMN production. Therefore, methods for increasing exon 7 inclusion levels of SMN2 spliced products were investigated. 2’OMe RNA annealer and enhancer sequences were synthesised based on Targeted Oligonucleotide Enhancers of Splicing (TOES) with the addition of HEG linkers and bioconjugation intermediates.

These observations are discussed with reference to previous studies of molten 2:1 salts, ion polarization effects and directional dependence of interionic forces.

However, this requires a clearer understanding of the relationship between the molecular structures of AXs and their immune-modulating activities (the structure-activity relationship).

Hydrogen is an emerging energy carrier for oil refining and fuel cell applications. The development of an efficient and stable catalyst to produce hydrogen gas is required for industrial applications.

Industrial catalysts that are frequently overwhelmed by such issues are substituted or re-treated, which is not time and cost efficient. Therefore, developing durable catalysts that are resistant to sintering and carbon fouling remains an area of interest. A

Abstract:

Après avoir mis au point une méthode d'identification et de quantification des triglycérides du beurre, un modèle de variation naturelle (saison et terroir) reliant la texture du produit à sa composition a pu être établi. Quatre groupes de triglycérides ont été identifiés comme étant des éléments déterminants de la variation naturelle de la fermeté du beurre. En tenant compte des résultats obtenus, deux procédés de modification de la texture ont été étudiés, procédés compatibles avec la conservation de l'image légale et traditionnelle du beurre: tout d'abord, une technique classique, fondée su

Abstract:

Les nouveaux matériaux carbonés modifiés par des films organiques constituent un domaine de recherche très actif depuis plusieurs décennies. Ces matériaux suscitent un intérêt grandissant dans les secteurs de l’énergie, de la santé et de l’environnement. Afin d’améliorer les performances de ces matériaux, les innovations reposent notamment sur la maîtrise de la fonctionnalisation des surfaces, le contrôle de la stabilité de la couche immobilisée ou encore sur les nouvelles propriétés liées à la modification. Selon les fonctions chimiques greffées, les applications sont multiples : détection et
