Scalar fluctuations of the scalar metric during inflation from a non-perturbative 5D large-scale repulsive gravity model

We develop a non-perturbative formalism for scalar metric fluctuations from a 5D extended version of general relativity in vacuum. In this work we concentrate our efforts on calculations valid on large cosmological scales, which are the dominant during the inflationary phase of the universe. The resulting metric in this limit is obtained after implementing a planar coordinate transformation on a 5D Ricci-flat metric solution. We calculate the spectrum of these fluctuations with an effective 4D Schwarzschild-de Sitter spacetime on cosmological scales, which is obtained after we make a static foliation on the non-compact extra coordinate. Our results show how the squared metric fluctuations of the primordial universe become scale invariant with the inflationary expansion.Comment: Final version to be published in EPJ

Will China’s economy continue growing, or it will start shrinking in the years to come?

Treballs Finals del Grau d'Empresa Internacional, Facultat d'Economia i Empresa, Universitat de Barcelona, Curs: 2019-2020 , Tutor: Àngels Pelegrín Solé[eng] Since China started its economic reforms back in 1978, developing from a closed and communist country, to the world second largest economy and the first trading nation in the world. In spite of its large growth, China is currently facing severe challenges that are questioning its ability to continue its growth trend and eventually becoming the first economy worldwide, surpassing the United States (US). This thesis aims to analyse whether China is eligible for further growth, or otherwise if its growth path is already over. In order to verify whether China will continue growing or not, China is compared with certain developed economies with the objective of understanding at which position is China nowadays. The results show that China is on the right track, but it is still far behind from world powers in terms of living standards.[spa] Desde que China empezó las reformas económicas en 1978, ha pasado de ser un país cerrado y comunista, a la segunda economía más grande y la primera nación comercial del mundo. A pesar de su gran crecimiento, China actualmente enfrenta desafíos severos que cuestionan su capacidad de continuar su tendencia de crecimiento y eventualmente convertirse en la primera economía mundial, superando a los Estados Unidos (EE. UU). Esta tesis tiene como objetivo analizar si China continuará su tendencia de crecimiento, o si su crecimiento ya ha llegado a su fin. Para verificar si China continuará creciendo o no, China será comparada con otras economías desarrolladas con el objetivo de comprender en qué posición se encuentra China en comparación con ellas. Los resultados muestran que China está en el camino correcto, sin embargo, todavía está muy por detrás de las potencias mundiales en términos de niveles de vida

Stakeholders participation in the Innovation Process

Master's thesis in Business InnovationThis master thesis aims to study the stages in which startups include relevant stakeholders in their innovation process. The study seeks to contribute and enrich the innovation management literature regarding stakeholder inclusion. It combines existing literature with the RRI field and adds non-economic stakeholders into the mix, with the aim to enhance the innovation management capabilities of Norwegian startups by conducting a research on the members of an organization in the Oslo region. The findings suggest that innovation is widely accepted and encouraged, it also shows that firms have dynamic capabilities since they are able to reflect, absorb and adapt to some degree their innovation based on stakeholder inclusion but that these interactions focus on primary economic relationships with informal meetings and networking as the main method. The evidence also shows that most stakeholder interactions are being held at the launch and post launch stages of a new product or service development. The study concludes making an argument for the inclusion of non-economic stakeholders to be done at earlier stages of the innovation proces

The present work intends to analyze the border remote control operations carried out by European countries and how such controls act in order to intercept ongoing migrations as well as to prevent the action of the refuge through the fabrication of sovereignty and jurisdiction beyond national territories.This article aims to raise a question about the procedures used to control migrations and the Modern State legitimacy when imposing restrictive border managing operations

Effect of different shades and post-activation times on Knoop hardness of resin cement

Orientador: Lourenço Correr SobrinhoDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: A polimerização adequada de cimentos resinosos é fundamental para obter excelentes propriedades físico-mecânicas. Fatores relacionados à cerâmica e ao próprio cimento podem influenciar a passagem de luz, reduzindo a fotoativação e alterando o grau de polimerização dos cimentos. O propósito neste estudo foi avaliar a dureza Knoop após 15 min ou 24h de diferentes cores de cimento resinoso fotoativado, com ou sem a interposição da cerâmica, em diferentes profundidades. Amostras com 5 mm de diâmetro e 1 mm de espessura do cimento resinoso Variolink Veneer (Ivoclar Vivadent) nas cores HV+1, HV+2, HV+3, MV0, LV-1, LV-2 e LV-3, foram feitas em um molde de elastômero, cobertas com uma tira de poliéster e por um disco de cerâmica IPS e.max Press (Ivoclar Vivadent) na espessura de 0,7 mm e fotoativadas por 20 segundos usando o LED Radii-cal (SDI Limited), com 1.200 mW/cm2. O cimento resinoso foi transversalmente desgastado e submetido ao teste de dureza Knoop usando o aparelho HMV 2 (Shimadzu), com carga de 50g aplicada por 15 segundos, 15 min após a fotoativação e após armazenagem a 37o C por 24 horas. Cinco penetrações foram feitas na secção transversal a 100 e 700 µm da superfície de topo, sendo que vinte amostras foram confeccionadas para cada cor do cimento resinoso Variolink Veneer em cada período de armazenagem. Os dados foram submetidos à Análise de Variância em esquema de parcelas subdivididas (cor, tempo pós-ativação, modo de ativação e profundidade), seguido pelo teste de Tukey post hoc (? = 0,05). Significante diferença para a cor (p0,05), exceto para a interação cor x tempo pós-ativação (p0.05), except for shade x post-cure time (p<0.0045) and mode of activation x post-cure time (p<0.0003). The resin cement shade and indirect activation had a significant effect on the Knoop hardness. There was a significant increase in Knoop hardness after 24 h in all cements shades. The depth influenced significantly on the Knoop hardnessMestradoMateriais DentariosMestra em Materiais Dentário

End-of-the-World Trade: On the Speculative Economies of Art and Extraction

Fri 21 June 3pm – 6pm : RHB 342 Sat 22 June 10 – 6 pm : RHB 312 This two-day event explores how ‘end-of-the-world’ scenarios and processes have given financial capitalism a new lease of life. Bringing together researchers, artists, theorists the event will consider how over the last decade financialisation has mutated new techniques of value extraction and emulation. All of which indicate emerging frontiers of social struggle spanning cultural, digital, geological, biological and sensual fields of knowledge and experience. The two watchwords of the larger research programme for this event are ‘extraction’ and ‘mimesis’. Extraction inasmuch as the scraping of value from exhausted resources is the current model of endgame capitalism, from the ‘gig economy’ to socially and geophysically devastating mining to the energy demands of the infrastructure servicing the digital economy, with cryptocurrency mining as the nexus where dominant as well as emergent models of social and energy extraction collide and comply. Here, emulation plays an important role, as capital increasingly mimics human biology and social exchange for profit, while the human and the social needs to retrofit itself as forms of capital in order to survive in a landscape of scarcity, commodification and debt. Mimesis is the worldmaking side of emulation, however, recalling aesthetic philosophies which re-imagine the nature-culture divide as not moving from exploitation to immersion, as much ‘new materialist’ thinking does, but to forms of mutual re-invention and adaptability which requires a profound shift in the material and social boundaries that reproduce nature and culture as polarities and as sites of escalating crisis. Art and financial technologies, specifically cryptocurrencies and all digital ledger-based forms of accounting, encapsulate both sides of the extraction/mimesis continuum, particularly with how contemporary cultural and political practices bring up close the agency of financial technologies in expanding the space of incalculability and contingency but also in enclosing the incalculable and sensate in routines of financial accumulation and extraction.

Optimización de técnicas de medida de dispersión cromática a frecuencias ópticas

En los últimos años la fibra óptica se ha convertido en el medio de transmisión principal para los sistemas de comunicación. Su capacidad de manejo de grandes cantidades de datos así como su inmunidad frente al ruido y el aislamiento eléctrico son algunas de las características que hacen que esta tecnología sea ideal para usarse en los sistemas de comunicación. Al objeto de explotar al máximo todo el potencial que ofrece la fibra, nos encontramos con que la dispersión cromática es el mayor limitante de la velocidad y distancia de transmisión de datos. En el departamento TSC se estudian nuevos métodos de caracterización de la dispersión cromática y se dispone de las herramientas de laboratorio necesarias para calcular su impacto. El objetivo principal del proyecto es estudiar las técnicas de medida de dispersión cromática ya existentes para analizar sus limitaciones y proponer así nuevos métodos que optimicen sus prestaciones. En concreto se presentarán tres métodos, el MPSM, el ABCM y el RF Scan. Realizaremos sus estudios teóricos que posteriormente nos permitirán contrastar sus resultados en el laboratorio. Los procesos de medida de la dispersión cromática en el laboratorio son controlados mediante ordenador. Se dispone de un primer prototipo de una interfaz gráfica denominada Fiber Test orientada a guiar al usuario durante el proceso de medida y a realizar los controles de instrumentos necesarios para llevar a cabo las medidas. Se propone como objetivo elaborar una nueva versión de la interfaz que racionalice la distribución de menús y que presente al usuario un entorno más amigable y visual, con nuevas opciones de interés y que permita que la interfaz vaya creciendo de manera modular para ir incorporando los nuevos métodos de medida que se van desarrollando. Hasta el momento la interfaz incorpora únicamente un método de medida. La idea es ampliar y mejorar la interfaz para que nos permita llevar a cabo las medidas correspondientes a los tres métodos mencionados anteriorment
