Approaching the diamond surface: first principles modelling the physics and chemistry of approaching radicals
No full textThe diamond surface plays a central role in much of the diamond research, and as such much of its properties are described and studied in great detail. There is a clear picture of the atomic scale structure of the different facets and their reconstructions. Also terminations with H, O, N and other atomic species as well as the incorporation of these elements has been modelled [1,2]. The electronic structure and the negative electron affinity mechanism is elucidated and so on. In contrast, however, the atomic scale models of diamond growth are much less developed, though progress is being made [3]. In these models the reaction barriers between stable and meta-stable intermediates are being calculated, providing insights into the kinetics of the surface. However, quantum mechanical models can provide much more insights than this. In this work, we simulated the approach of radical atoms and molecules towards the H-terminated diamond 001 surface. By allowing the model to equilibrate at every step, the physics and chemistry of the approach can be followed in minute detail. It allows us to indicate at which distance the surface and radical start interacting, and what that interaction entails. The charge evolution of the radical and the surface is followed by means of Hirshfeld-I charges, providing insights into charge transfer mechanisms. [4] Throughout the approach, the interaction can be followed through different physical and chemical concepts. Different types of bonding are identified as well as H-abstraction events and covalent bonding. In this work, our focus goes to C and P based radicals, showing them to behave very differently near the surface, providing insights into the requirements for improved P incorporation.The author name needs to be updated to include the middle names: Danny E.P.

Plataforma para la gestión de proyectos de investigación e investigadores de la Universidad Tecnológica de Panamá, aplicando la metodología de Experiencia de Usuario
No full textLa metodología de Experiencia de Usuario es la satisfacción del usuario al interactuar con un producto, servicio o sistema. Esta metodología brinda grandes beneficios ya que contempla aspectos importantes como lo es el diseño, la tecnología y el modelo de negocio de datos. Estos factores son importantes, sin embargo, no se tomaron en cuenta al desarrollar el sistema anterior, lo que impide obtener y generar indicadores para su análisis.

First person – Danny Legge
No full textFirst Person is a series of interviews with the first authors of a selection of papers published in Disease Models & Mechanisms (DMM), helping early-career researchers promote themselves alongside their papers. Danny Legge is first author on ‘BCL-3 promotes a cancer stem cell phenotype by enhancing β-catenin signalling in colorectal tumour cells’, published in DMM. Danny conducted the research described in this article while a PhD student in Professor Ann Williams's lab at Colorectal Tumour Biology Group, School of Cellular and Molecular Medicine, University of Bristol, UK. He is now a postdoc in the lab of Dr Keith Brown at Cancer Epigenetics Laboratory, School of Cellular and Molecular Medicine, University of Bristol, UK, investigating the role of cancer stem cells in colorectal cancer

Character of Danny Smiřický in selected Škvorecký's novels
No full textThe aim of this thesis is to examine the development of a literary character, Danny Smiřický, reoccuring in many of Josef Škvorecký's novels and representing both the role of a storyteller and a protagonist. The work mainly focuses on the way Danny Smiřický's character was constructed, describes his personality, life fates, relations to other characters and in this light, also, to observe changes the Czech society was undergoing throughout the twentieth century. Attention is drawn to the specific language used by Danny and his peers which acts, in a remarkable way, as a means of authenticity. It also largely helps to convey the generational testimony. For the analysis, selected literary texts written by Škvorecký are used, in which Danny appears and which follow in a chronological order. The work specifically analyzes the novel's Cowards, Swell season, and Tank battalion. Danny Smiřický is often considered an autobiographical character, in other words, the alter ego of the author. This is where the importance of the character comes from. KEYWORDS Danny Smiřický, Josef Škvorecký, literary character, characteristic, autobiographical element
