Abstract:

A radiação UV pode causar danos à pele humana, e, evitar estes danos, é uma preocupação crescente para a população e um desafio à comunidade científica. Para uma ação efetiva de fotoproteção, a associação de filtros, como avobenzona (BMBM) e ρ-metoxicinamato de octila (EHMC), são empregados. Devido à semelhança estrutural com os filtros solares químicos, a rutina (RUT), tal como outros flavonoides, apresenta atividade fotoprotetora. Apesar da disponibilidade de diferentes classes de filtros solares, o desenvolvimento de fotoprotetores contendo filtros químicos é um desafio, devido à insta

Abstract:

This dissertation has two intersecting foci; firstly, the discovery of a new methodology for the growth of high surface area cuprous oxide (Cu2O) substrates. Secondly, the synthesis and characterization of electron-accepting molecules, and their incorporation into excitonic solar cells (XSCs) using the Cu2O substrates as electrodes. Increasing the surface area of the semiconductor creates more locations for charge transfer to occur thus increasing the overall efficiency of the device. Zinc oxide (ZnO) has been widely studied, and can be easily grown into many different films with high surface

Abstract:

This dissertation has focused on studying the effect of four glycine derivatives on the solid state properties of mannitol, glycine, and sucrose when freeze dried into blended mixtures. The primary goal was to assess their value for use in the stabilisation of vaccines in the solid state, by examining key physical and chemical characteristics, which have been documented to be beneficial to the stabilisation of biopharmaceutical formulations. The novel excipients; dimethyl glycine, and trimethyl glycine, were shown to retard the crystallisation and increase the overall glass transition temperat

Dans le but d'améliorer le rendement des cellules à colorant de type p (DSSC-p), ces travaux s'attachent à la synthèse et la caractérisation de matériaux semi-conducteurs de type p (SCs-p) sous forme de nanoparticules. En ce sens, des SCs-p répondant à un cahier des charges (bande de valence basse en énergie, grande surface spécifique, bon conducteur et bonne transparence) ont été étudiés. Dans ce cadre, une stratégie a été développée pour améliorer les propriétés de NiO (l'actuel matériau de référence) en optimisant sa nanostructuration, sa forte non-stœchiométrie en nickel et par son dopage

Abstract:

This thesis addresses the quality of ‘difference’ in L2 English argumentative essays written by Japanese students by focusing on the use of metadiscursive nouns. It does this by comparing the similarities and differences in the use of 33 shell nouns (Schmid, 2000) as discourse construction devices in two corpora: the Japanese subcorpus of ICLE – Japanese writing in English as a foreign language – and the US subcorpus of LOCNESS – Americans writing in English as a first language. Based on Schmid’s (2000) theory, discourse roles of shell nouns are analysed according to three aspects: noun freque

Abstract:

The purpose of this study was to determine whether the Anxiety Disorders Interview Schedule for DSMâ IV: Parent Version (ADISâ P) is a valid diagnostic tool in assessing Oppositional Defiant Disorder (ODD) in youth. Although there is considerable evidence that the ADISâ P is effective when diagnosing anxiety disorders in youth, no studies have yet examined its utility in assessing ODD, even though the ADISâ P contains an ODD module. In contrast, a number of studies support the Diagnostic Interview Schedule for Childrenâ Version IV (DISCâ IV) as a reliable and valid tool for assessing ODD

Abstract:

This thesis is a contribution to the field of learner corpus studies. It compares a number of different measures of accuracy and complexity in second language writing, applying those measures to a sample of 308 essays written by Kurdish university students majoring in English in three schools in Iraqi Kurdistan (at two years of study: third year and fourth year). It proposes an innovative method for measuring correctness, and integrates a number of different measures of accuracy into an Integrated Approach to Achievement.

Abstract:

Willingness to communicate in a second language (L2 WTC) has become an important focus of inquiry in applied linguistics over the last decade or so. However, little is currently understood about the practical tasks of producing communicatively competent L2 users in Chinese higher education, an aim which has been fully recognized by the English language teaching (ELT) sector in China. In order to fill this gap, this research study was conducted in one of the universities in mid-east China over a period of one academic term with the aim to produce an empirically-supported fine-grained portrait o

Abstract:

In the first part of the present study the immune responses in NIH mice against asexual blood stages of either avirulent DK or virulent DS strains of P. chabaudi adami, in single or mixed infections, were examined using the ELISA test for the detection and measurement of cytokine and antibody production. The present results showed that the profile of the immune response in all the above infections suggests a sequential Thl/Th2 CD4+ T cell response. Previous studies have shown that there is a sequential Thl/Th2 response in Plasmodium chabaudi AS infection which is reflected in the activation of

Abstract:

Inflammatory bowel diseases, (IBD), are a group of chronic disorders of the gastro-intestinal tract, and include Crohn’s disease (CD) and Ulcerative Colitis (UC). The pathogenesis is not known, but involves at least in part a loss of tolerance towards the commensal colonic microbiota. In this thesis, we show in animal models of CD and UC that the colonic mucosal blood flow increased compared to healthy animals. This blood flow increase is due to an up regulation of endothelial nitric oxide synthase (NOS). Further, we show in the UC model that the thickness of the firmly adherent colonic mucus

Abstract:

Wavelength division multiplexing (WDM) is essential for further enhancement of the transmission capacities of optical telecommunication systems. Key devices in WDM networks are multiplexing/demultiplexing components, which enable the combination/separation of several carrier waves with different wavelengths for the purpose of simultaneous transmission through one optical fibre. These components can be realized using Bragg diffraction from volume holographic gratings. Especially reflection holograms provide a pronounced wavelength selectivity which makes them attractive for free-space WDM
