A CONFLITUOSA RELAÇÃO DAS ASSEMBLEIAS DE DEUS BRASILEIRAS E A TELEVISÃO: DA PROIBIÇÃO À ACEITABILIDADE

Esta pesquisa busca abordar e analisar os caminhos da mídia televisiva nas igrejas Assembleias de Deus no Brasil, aqui trabalhadas no plural devido às muitas ramificações da denominação, em suas construções das representações simbólicas, imaginárias, culturais e midiáticas. O objetivo é analisar a dimensão simbólica na proibição do uso da televisão na denominação religiosa em questão, e os argumentos para o veto entre os fiéis, a discreta aceitabilidade da TV diante das novas concepções teológicas das ADs ao longo dos anos, investimento em canal aberto (Rede Boas Novas de Televisão) e proposta de um programa televisivo como marca midiática da denominação (Programa Movimento Pentecostal). Para viabilidade desse trabalho, a metodologia adotada consiste em pesquisa bibliográfica histórica, com foco nos temas fundamentais para o desenvolvimento das pesquisas do imaginário, identidade, cultura, nação e televisão, aliada à pesquisa documental, que tem como meta os registros históricos, que melhor elucidarão os caminhos e a ligação da TV com as Assembleias de Deus.

Growth of ultrananocrystalline diamond film by DC Arcjet plasma enhanced chemical vapor deposition

Self-standing diamond films were grown by DC Arcjet plasma enhanced chemical vapor deposition (CVD). The feed gasses were Ar/H 2/CH 4, in which the flow ratio of CH 4 to H 2 (FCH4/FH2) was varied from 5% to 20%. Two distinct morphologies were observed by scanning electron microscope (SEM), i.e. the pineapple-like morphology and the cauliflower-like morphology. It was found that the morphologies of the as-grown films are strongly dependent on the flow ratio of CH 4 to H 2 in the feed gasses. High resolution transmission electron microscope (HRTEM) survey results revealed that there were nanocrystalline grains within the pineapple-like films whilst there were ultrananocrystalline grains within cauliflower-like films. X-ray diffraction (XRD) results suggested that (110) crystalline plane was the dominant surface in the cauliflower-like films whilst (100) crystalline plane was the dominant surface in the pineapple-like films. Raman spectroscopy revealed that nanostructured carbon features could be observed in both types of films. Plasma diagnosis was carried out in order to understand the morphology dependent growth mechanism. It could be concluded that the film morphology was strongly influenced by the density of gas phases. The gradient of C2 radical was found to be different along the growth direction under the different growth conditions. © 2012 Elsevier B.V. All rights reserved.

Design and performance assessment of aortic heart valve for tissue engineering

Current artificial heart valves are classified as mechanical and bioprosthetic. An appealing pathway that promises to overcome the shortcomings of commercially available heart valves is offered by the interdisciplinary approach of cardiovascular tissue engineering. However, the mechanical properties of the Tissue Engineering Heart Valves (TEHV) are limited and generally fail in the long-term use. To meet this performance challenge novel biodegradable triblock copolymer poly(ethylene oxide)-polypropylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO or F108) crosslinked to Silk Fibroin (F108-SilkC) to be used as tri-leaflet heart valve material was investigated. ^ Synthesis of ten polymers with varying concentration and thickness (55 µm, 75 µm and 100 µm) was achieved via a covalent crosslinking scheme using bifunctional polyethylene glycol diglycidyl ether (PEGDE). Static and fatigue testing were used to assess mechanical properties of films, and hydrodynamic testing was performed to determine performance under a simulated left ventricular flow regime. The crosslinked copolymer (F108-Silk C) showed greater flexibility and resilience, but inferior ultimate tensile strength, by increasing concentration of PEGDE. Concentration molar ratio of 80:1 (F108: Silk) and thickness of 75 µm showed longer fatigue life for both tension-tension and bending fatigue tests. Four valves out of twelve designed satisfactorily complied with minimum performance requirement ISO 5840, 2005. ^ In conclusion, it was demonstrated that the applicability of a degradable polymer in conjugation with silk fibroin for tissue engineering cardiovascular use, specifically for aortic valve leaflet design, met the performance demands. Thinner thicknesses (t<75 µm) in conjunction with stiffness lower than 320 MPa (80:1, F108: Silk) are essential for the correct functionality of proposed heart valve biomaterial F108-SilkC. Fatigue tests were demonstrated to be a useful tool to characterize biomaterials that undergo cyclic loading. ^

Fabrication of sub-10 nm lamellar structures by solvent vapour annealing of block copolymers

Fabrication of nanoscale patterns through the bottom-up approach of self-assembly of phase-separated block copolymers (BCP) holds promise for nanoelectronics applications. For lithographic applications, it is useful to vary the morphology of BCPs by monitoring various parameters to make “from lab to fab” a reality. Here I report on the solvent annealing studies of lamellae forming polystyrene-blockpoly( 4-vinylpyridine) (PS-b-P4VP). The high Flory-Huggins parameter (χ = 0.34) of PS-b-P4VP makes it an ideal BCP system for self-assembly and template fabrication in comparison to other BCPs. Different molecular weights of symmetric PS-b-P4VP BCPs forming lamellae patterns were used to produce nanostructured thin films by spin-coating from mixture of toluene and tetrahydrofuran(THF). In particular, the morphology change from micellar structures to well-defined microphase separated arrangements is observed. Solvent annealing provides a better alternative to thermal treatment which often requires long annealing periods. The choice of solvent (single and dual solvent exposure) and the solvent annealing conditions have significant effects on the morphology of films and it was found that a block neutral solvent was required to realize vertically aligned PS and P4VP lamellae. Here, we have followed the formation of microdomain structures with time development at different temperatures by atomic force microscopy (AFM). The highly mobilized chains phase separate quickly due to high Flory-Huggins (χ) parameter. Ultra-small feature size (~10 nm pitch size) nanopatterns were fabricated by using low molecular weight PSb- P4VP (PS and P4VP blocks of 3.3 and 3.1 kg mol-1 respectively). However, due to the low etch contrast between the blocks, pattern transfer of the BCP mask is very challenging. To overcome the etch contrast problem, a novel and simple in-situ hard mask technology is used to fabricate the high aspect ratio silicon nanowires. The lamellar structures formed after self-assembly of phase separated PS-b-P4VP BCPs were used to fabricate iron oxide nanowires which acted as hard mask material to facilitate the pattern transfer into silicon and forming silicon nanostructures. The semiconductor and optical industries have shown significant interest in two dimensional (2D) molybdenum disulphide (MoS2) as a potential device material due to its low band gap and high mobility. However, current methods for its synthesis are not ‘fab’ friendly and require harsh environments and processes. Here, I also report a novel method to prepare MoS2 layered structures via self-assembly of a PS-b-P4VP block copolymer system. The formation of the layered MoS2 was confirmed by XPS, Raman spectroscopy and high resolution transmission electron microscopy.

May the Giant Be With You: Twin Peaks Season Two, Episode One and the Television Auteur

The premiere of Season Two of Twin Peaks garnered some of the highest ratings of the series, with celebrated filmmaker and co-creator David Lynch stepping back into the director’s chair. Yet, within this episode many traditional television conventions are flouted, and in response the following week the ratings dropped dramatically. From its slow-paced opening scenes in which an old man admonishes the wounded, bleeding protagonist to drink his warm milk before it gets cold, followed by a vision of a giant speaking in riddles, this episode not only tested its audience’s patience but also seemed to set out to deliberately confuse them. In this essay I will explore how this episode is an example of auteur television, an episode in which the director expresses a consistency of style and theme that is similar to their other work, as well as examine how Lynch’s approach to televisual aesthetics has influenced the way that contemporary film directors have crossed over into the television medium. However, when taking into account the differences in the two media of film and television notions of authorship, with regards to the position of the director, become complicated, especially when considering contemporary television and the rise of the showrunner as key creative force. Even when looking back at Lynch’s contribution to Twin Peaks it becomes clear that the series was deeply collaborative, with Lynch absent during parts of the filming. Yet, when examining the extensive material that has been written about Twin Peaks there is still a continuing tendency to place Lynch as the sole author. The placement of Lynch as author can be argued in relation to the episodes he directed (as will be explored below in relation to the first episode of Season Two), but cannot be attributed to him alone when considering the series as a whole. Finally, I will discuss how the figure of the television auteur has become a central element of television reception rather than production, an integral part of a viewer’s search for narrative meaning in a medium where complexity and mystery are now expected and enjoyed. Just as fans scrambled to uncover the many secrets and mysteries of Twin Peaks by looking to Lynch’s other works for answers, a similar process is experienced by fans of television shows existing today.
