Abstract:

A range of small molecules of interest for use in organic semiconductor devices were studied computationally. Trends in geometry, absorption spectra, molecular orbitals, electrostatic potentials, reorganisation energies were studied. Results suggest that, as with acenes, the performance of non-linear cata-condensed polyaromatic hydrocarbons improves as number of fused benzene rings increases. The torsion in these molecules did not appear to have a large impact on the conjugation across the core and little effect on the absorption spectra, although it did affect the reorganisation energies on w

Abstract:

Ce mémoire vise à questionner les liens entre l'auteur, sa posture, sa figure et la réception critique de son oeuvre. Depuis que Michel Foucault a défini l'auteur comme étant un"être de raison", les études portant sur la figure de l'auteur se sont déployées, suivant le développement de la sociologie de la littérature et l'étude des trajectoires d'écrivains. Un sujet cependant reste guère exploité : peu de recherches se penchent sur le rôle que joue la"façon d'être" d'un écrivain sur la figure qui en découle par la suite, et qui est nécessairement construite par l'ensemble des agents du champ.

The measurements were done with a dual rotating compensator ellipsometer. The measured wavelength region was from 240 to 1000 nm and the angle of incidence from 25° to 75° in most of the cases.

Light reflected from the scarab beetles Cetonia aurata (C. aurata) and Chrysina gloriosa (C. gloriosa) has left-handed polarization. In this work the polarizing properties and structural characteristics of the cuticles of these two beetles are investigated with two different techniques: scanning electron microscopy (SEM) and Mueller-matrix spectroscopic ellipsometry (MMSE). SEM is used to get cross section images of the epicutucle and the endocuticle. Thicknesses around 18 μm were measured for both layers for C. aurata and between 12 and 16 μm for C. gloriosa.

Abstract:

Conversations among scholars in the study of Chaucer have been essential in constructing the foundations on which we now stand. However, in light of recent pressures in the very competitive and practical aspects of academic life, the scholarly conversation is often lost amidst the desire to find any obscure point on which to publish simply for the reason that no one has yet said anything about it. There is certainly a usefulness to exploring all facets of Chaucer's work, but there is also a need to slough off the cumbersome coat of 'publish-or-perish' scholarship in favor of carrying on a more

Chrysin has been shown as a potent aromatase inhibitor, which may increase the concentration of serum and urinary testosterone and lead to violate the doping control rule. However, the effects of the chrysin supplementation on blood and urinary testosterone levels in human have yet to be elucidated. PURPOSE: This study was to investigate whether the chrysin supplementation would increase serum testosterone by altering the synthesis of the testosterone pathway. Moreover, the ratio of testosterone to epit

They are located mostly in the mid- and low-latitude regions of the northern hemisphere of Mars. The formation of the plateau-like crater rims has been suggested to be caused by the mixing of the impact ejecta with water vapor during the impact explosion. Their distribution has therefore been used as indicators of potential sites of underground water or subsurface ice. In addition, their shapes and morphologies can provide important

Studies showed that Ni-exposure promotes the invasive potential of human lung cancer cells through TLR4 signaling. Quercetin and chrysin, two flavonoids, are ubiquitously present in vegetables and fruits. Our previous study found that quercetin and chrysin significantly inhibited Ni-induced invasion and migration in human lung cancer cells. However the possible mechanisms are unclear. Thus, the present study investigated whether quercetin and chrysin inhibit the effects of Ni through the regulatio

It can initiate a multitude of biological effects through the activation of transmembrane protein tyrosine kinase receptor-PDGF receptor- (PDGFR-) contributing to SM

Cancer is one of the leading causes of death worldwide. Owing to the complex ways in which this disease develops, there is a constant demand for new drugs. Natural products have delivered great promise in inspiring chemotherapy, for example, Taxol, Trabectedin, Plinabulin, Marizomib, Midostaurin, etc. Endophytic fungi have potentiated this promise by producing potent bioactive compounds. They live symbiotically in the internal tissues of higher organisms. Marine endophytic fungi offer a diverse chemical space for the discovery of novel anticancer compounds, sustainably.

RESUMO: A ocorrência de neoplasias malignas é considerada um dos principais problemas de saúde pública ao nível mundial, sendo a segunda causa de morte em países desenvolvidos. Nos últimos 10 anos, os avanços na terapêutica utilizada no tratamento do cancro veio aumentar a taxa de sobrevivência dos doentes oncológicos. Infelizmente, a doença metastática é ainda a principal responsável pela mortalidade e morbilidade associadas à doença. Em 2000, Hanahan e Weinberg publicaram a sistematização das principais características da transformação maligna em seis categorias: autossuficiência para a pr
