Colapso gravitacional na teoria de Hořava-Lifshitz no limite infravermelho

O objetivo desta tese é verificar se algumas soluções de matéria da teoria da relatividade geral também satisfazem as equações da teoria de Horava-Lifshitz no limite infravermelho. Para isso, partimos das soluções mais simples possíveis, tais como é o caso de um fluido de radiação nula e de poeira, conhecidas na relatividade geral, e encontramos que estas não correspondem a quaisquer soluções na teoria de gravitação de Hořava-Lifshitz para o limite de baixas energias, infravermelho, no qual esta teoria deveria se reduzir à anterior. Este resultado nos remete a novos desafios na direção de ajustes teóricos que permitam que esta teoria descreva corretamente tanto o cenário cosmológico quanto o de formação de estruturas, estáveis ou colapsadas. Para tornar o trabalho mais claro, é feita uma introdução à teoria de Hořava- Lifshitz, tema central deste trabalho, e como ela se acopla com a matéria.

Spectacle and publics: Ava Gardner in Australia 1959

Ava Gardner’s famous line about Melbourne being the right place to film a story about the end of the world was part of the spectacle created by the print media to capitalise on her presence here to film, On the Beach in 1959. Gardner’s refusal to appear in public created different responses from the Australian print media the most interesting of which was Melbourne’s The Truth. With the help of a fledgling paparazzi, Truth used Gardner’s non-appearance to create a fictitious image of her which was mediated to create extremes of public opinion in order to generate sales. This paper examines The Truth ’s response to Gardner in the context of the creation and manipulation of public spectacle.

A imprensa em Avaí: a cidade e o urbano no Avahy-Jornal, 1927-1931

Esta monografia é resultado da pesquisa de iniciação científica “A imprensa em Avaí: a cidade e o urbano no AVAHY-JORNAL, 1927 – 1931”, e tem por objetivo fazer um levantamento e mapeamento de temas sobre as dinâmicas e transformações urbanas da cidade de Avaí - localizada na região oeste paulista -, presentes no periódico “AVAHY-JORNAL” no período compreendido entre novembro de 1927 a dezembro de 1931. Por meio da articulação entre a leitura e fichamento do jornal, documentação específica sobre o município e fontes bibliográficas das temáticas acerca da Cidade e do Urbano, História da Imprensa, História de Avaí, da região e do estado de São Paulo, este trabalho também pretende esboçar uma problematização sobre a questão social, política e econômica de Avaí do final dos anos 1920 e início dos anos 1930, além de analisar o veículo pesquisado

Configurando um AVO (Ambiente Virtual Anise de Abreu Gonçalves D'Orange Ferreira de Orientação): instrumentação de um professor em proposta de incentivo ao uso de TIC e AVA no nível de pós-graduação

In this paper, I will present a proposal for teachers’instrumentation in ICT by the configuration of a virtual learningenvironment (MOODLE) for advising Linguistics graduate students’projects on teacher education and language teaching mediated by digitaltechnologies. The context of the proposal is teaching as work,occasioned by an announcement from the IHE to encourage the use ofICT. Following the theoretical assumptions adopted by the ALTERresearch group, and confronted with the goals set in the text of theannouncement, the instrumentation involved the reorganization ofcontents provided by a graduate course in the research process steps:planning, implementation and dissemination, and of the artifactsaffordances: information, communication and production.

Seismic modelling and ava analysis of hidrocarbon traps

In this study, forward seismic modelling of four geological models with Hydrocarbon (HC) traps were performed by ray tracing method to produce synthetic seismogram of each model. The idea is to identify the Hydrocarbon Indicators (HCI‟s) such as bright spot, flat spot, dim spot and Bottom Simulating Reflector (BSR) in the synthethic seismogram. The modelling was performed in DISCO/FOCUS 5.0 seismic data processing programme. Strong positive and negative reflection amplitudes and some artifact reflection horizons were observed on produced seismograms due to rapid changes in subsurface velocity and geometry respectively Additionally, Amplitude-versus-angle (AVA) curves of each HCIs was calculated by the Crewes Zoeppritz Explorer programme. AVA curves show that how the reflection coefficients change with the density and the P and S wave velocities of each layer such as oil, gas, gas hydrate or water saturated sediments. Due to AVA curves, an increase in reflection amplitude with incident angle of seismic waves corresponds to an indicator of a hydrocarbon reservoir

Understanding mild acid pretreatment of sugarcane bagasse through particle scale modeling

Sugarcane bagasse is an abundant and sustainable resource, generated as a by-product of sugarcane milling. The cellulosic material within bagasse can be broken down into glucose molecules and fermented to produce ethanol, making it a promising feedstock for biofuel production. Mild acid pretreatment hydrolyses the hemicellulosic component of biomass, thus allowing enzymes greater access to the cellulosic substrate during saccharification. A particle-scale mathematical model describing the mild acid pretreatment of sugarcane bagasse has been developed, using a volume averaged framework. Discrete population-balance equations are used to characterise the polymer degradation kinetics, and diffusive effects account for mass transport within the cell wall of the bagasse. As the fibrous material hydrolyses over time, variations in the porosity of the cell wall and the downstream effects on the reaction kinetics are accounted for using conservation of volume arguments. Non-dimensionalization of the model equations reduces the number of parameters in the system to a set of four dimensionless ratios that compare the timescales of different reaction and diffusion events. Theoretical yield curves are compared to macroscopic experimental observations from the literature and inferences are made as to constraints on these “unknown” parameters. These results enable connections to be made between experimental data and the underlying thermodynamics of acid pretreatment. Consequently, the results suggest that data-fitting techniques used to obtain kinetic parameters should be carefully applied, with prudent consideration given to the chemical and physiological processes being modeled.

Metabolic dysfunction and laminitis

Objective: This review focuses on laminitis that develops as a result of metabolic dysfunction and aims to provide a concise assessment of the current state of knowledge on this form of the disease. Outline: The most prevalent form of laminitis is associated with metabolic or endocrinopathic diseases, such as Equine Metabolic Syndrome and pituitary pars intermedia dysfunction, and the feeding of high-energy diets, particularly those rich in non-structural carbohydrates. Insulin dysregulation is the key hormonal imbalance implicated in causing this form of laminitis and hyperinsulinaemia is an important risk factor for the disease. Hyperinsulinaemia can occur in association with insulin resistance, obesity, regionalised adiposity, dysregulated cortisol metabolism and may also be related to other factors, such as breed and genetic predisposition. Recognition of hyperinsulinaemia is best achieved by using a dynamic oral glucose test that can be performed relatively easily under field conditions. Insulin produces a unique pathological lesion in the lamellae and the features of this lesion have informed investigations on the pathogenesis of the disease. Research into the mechanism of disease is continuing so that more targeted therapies than are currently available can be developed. However, dietary restriction and exercise remain effective management strategies for metabolic disease. Conclusions: Although the pathogenic mechanism/s of metabolic and endocrinopathic forms of laminitis remain the subject of intense research, ample data on risk factors for the disease are available. Efforts focussed on preventing the disease should aim to identify metabolic disease and reduce obesity and insulin resistance in at-risk individuals.
