A crença no arrebatamento da Igreja: seus desenvolvimentos e transformações imagéticas.

A crença no arrebatamento da Igreja faz parte de um sistema escatológico fundamentalista que costuma ser chamado de dispensacionalismo pré-milenista. Seu surgimento se dá a partir do século XIX, pelo ensino de John Nelson Darby, um pregador evangélico britânico, fundador dos Irmãos de Plymouth. Seu ensino aguarda a vinda de Cristo em duas etapas: uma, em secreto para a Igreja, há de levá-la ao Céu e poupá-la dos sete anos de tribulação que se seguirão; e outra, num aparecimento glorioso, ao final dos sete anos há de instaurar o reino milenial sobre a terra. O ensino de Darby foi popularizado nas notas de rodapé da Bíblia de Referência Scofield, publicada em 1909 por Cyrus I. Scofield, e ainda hoje se configura na crença escatológica da maioria das igrejas evangélicas fundamentalistas, tanto nos EUA quanto no Brasil. Em 2002 foi produzido o filme: Deixados para Trás que retrata esta crença bem como sua atualização para épocas recentes. Contudo, um estudo mais aprofundado desta crença expõe seu caráter de construto doutrinário, em que textos bíblicos de perspectivas diferentes, do Antigo e do Novo Testamento, são unidos para formar um quadro escatológico em vias de se cumprir.(AU)

DA PENA À PELÍCULA: AS PERSONAGENS DE CARANDIRU

Este estudo enfoca a transposição da obra literária Estação Carandiru, de Drauzio Varella, para o cinema, no que tange à construção de suas personagens. Para tanto, fez-se um levantamento das personagens e de suas características, de ambas as obras. O objetivo maior é compreender as escolhas feitas durante este diálogo entre mídias, que originou o filme Carandiru, de Hector Babenco, visto que houve uma grande redução no número de personagens. Para esta análise, adotou-se a pesquisa descritiva como procedimento metodológico. Constatou-se que a maior parte das origens das personagens cinematográficas vem de fusões de personagens literárias. Mas também foram encontradas personagens literárias que foram desmembradas e algumas que foram eliminadas. Não se encontrou nenhuma personagem acrescentada.(AU)

Desenvolvimento de bionanocompósitos: nano e microcristais de celulose com poli (álcool vinílico) e poli (ácido lático)

This work has the main objective to obtain nano and microcrystals of cellulose, extracted from the pineapple leaf fibres (PALF), as reinforcement for the manufacture of biocomposite films with polymeric matrices of Poly(vinyl alcohol) (PVA) and Poly(lactic acid) (PLA). The polymer matrices and the nano and microcrystals of cellulose were characterised by means of TGA, FTIR and DSC. The analysis was performed on the pineapple leaves to identify the macro and micronutrients. The fibers of the leaves of the pineapple were extracted in a desfibradeira mechanical. The PALF extracted were washed to remove washable impurities and subsequently treated with sodium hydroxide (NaOH) and sodium hypochlorite (NaClO) in the removal of impurities, such as fat, grease, pectates, pectin and lignin. The processed PALF fibers were hydrolysed in sulfuric acid (H2SO4) at a concentration of 13.5 %, to obtain nano and microcrystals of cellulose. In the manufacture of biocomposite films, concentrations of cellulose, 0 %, 1 %, 3 %, 6 %, 9% and 12% were used as reinforcement to the matrices of PVA and PLA. The PVA was dissolved in distilled water at 80 ± 5 oC and the PLA was dissolved in dichloromethane at room temperature. The manufacture of biocompósitos in the form of films was carried out by "casting". Tests were carried out to study the water absorption by the films and mechanical test of resistance to traction according to ASTM D638-10 with a velocity of 50 mm/min.. Chi-square statistical test was used to check for the existence of significant differences in the level of 0.05: the lengths of the PALF, lengths of the nano and microcrystals of cellulose and the procedures used for the filtration using filter syringe of 0.2 μm or filtration and centrifugation. The hydrophilicity of biocompósitos was analysed by measuring the contact angle and the thickness of biocompósitos were compared as well as the results of tests of traction. Statistical T test - Student was also applied with the significance level (0.05). In biodegradation, Sturm test of standard D5209 was used. Nano and microcrystals of cellulose with lengths ranging from 7.33 nm to 186.17 nm were found. The PVA films showed average thicknesses of 0.153 μm and PLA 0.210 μm. There is a strong linear correlation directly proportional between the traction of the films of PVA and the concentration of cellulose in the films (composite) (0,7336), while the thickness of the film was correlated in 0.1404. Nano and microcrystals of cellulose and thickness together, correlated to 0.8740. While the correlation between the cellulose content and tensile strength was weak and inversely proportional (- 0,0057) and thickness in -0.2602, totaling -0,2659 in PLA films. This can be attributed to the nano and microcrystals of cellulose not fully adsorbed to the PLA matrix. In the comparison of the results of the traction of the two polymer matrices, the nano and microcrystals have helped in reducing the traction of the films (composite) of PLA. There was still the degradation of the film of PVA, within a period of 20 days, which was not seen in the PLA film, on the other hand, the observations made in the literature, the average time to start the degradation is above 60 days. What can be said that the films are biodegradable composites, with hydrophilicity and the nano and microcrystals of cellulose, contribute positively in the improvement of the results of polymer matrices used.

Manifestações oculares em mulheres com síndrome dos ovários policísticos: prevalência e associação com fatores de risco metabólicos e inflamatórios

Objetivos: Estimar a prevalência de alterações do filme lacrimal e da doença do olho seco (DOS), comparar as mudanças na pressão intraocular (PIO) e comparar as espessuras macular e da camada de fibras nervosas da retina (CFNR), entre mulheres com síndrome dos ovários policísticos (SOP) e mulheres saudáveis, estratificando-as em condições clínicas, metabólicas e inflamatórias. Metodologia: O estudo incluiu 45 mulheres com SOP e 47 mulheres saudáveis ovulatórias submetidas a avaliações clínico-ginecológicas e oftalmológicas, incluindo propedêuticas para a avaliação do filme lacrimal e medida da PIO, e medição da espessura macular, da CFNR e parâmetros do disco óptico usando tomografia de coerência óptica. Resultados: Tempo de ruptura do filme lacrimal (TRFL; p=0.001) e impregnação por fluoresceína (p=0.006) apresentaram diferenças estatisticamente significantes entre os grupos estudados. A prevalência de DOS foi de 44,4% nas portadoras de SOP. Houve redução estatisticamente significativa do TRFL na presença de SOP (p=0.001). Além disso, houve efeito estatisticamente significativo de intolerância à glicose e síndrome metabólica/inflamação na impregnação por fluoresceina (p=0.004; p=0.015, respectivamente). A PIO encontrou-se estatisticamente mais elevada no grupo SOP que no grupo controle (p=0.011). Houve um aumento na média do IPC (índice pressão-córnea) com a associação entre SOP e da síndrome metabólica (p = 0.005); A média da espessura da CNFR superior ao redor do nervo óptico foi estatisticamente mais espessa nas voluntárias com SOP que nas voluntárias saudáveis (p=0.036); Após estratificação pela presença de resistência insulínica, as médias dos subcampos das espessuras maculares “macular interno temporal, macular interno inferior, macular interno nasal e macular externo nasal, foram mais espessas no grupo SOP que no grupo controle (p<0.05); Houve associação significativa entre obesidade e resistência insulínica (p=0.037), e intolerância à glicose (p=0.001), com aumento médio do componente principal 1 (CP1), e, na presença de síndrome metabólica (p<0.0001), com aumento médio do componente principal 2 (CP2), respectivamente, em relação à espessura macular total. Na presença de obesidade e inflamação, houve redução no escore médio da CP2 (p=0.034), em relação à espessura da CFNR na mácula. xviii Conclusões: Há uma associação da SOP, suas alterações metabólicas e inflamatórias com alterações do filme lacrimal e com mudanças na PIO. A diminuição na espessura da CFNR macular e aumento da espessura total macular estão possivelmente associadas às alterações metabólicas, e, o aumento na espessura da CFNR ao redor do nervo óptico estão provavelmente associadas às alterações hormonais, inerentes à SOP.

Desenvolvimento de novos biolubrificantes hidráulicos derivados dos óleos de maracujá e de moringa in natura e epoxidados

With the increasing environmental awareness, maximizing biodegradability and minimizing ecotoxicity is the main driving force for new technological developments. Thus, can be developed new biodegradable lubricants for use in environmentally sensitive areas. The aim of this study was to obtain new bio-lubricants from passion fruit (Passiflora edulis Sims f. flavicarpa Degener) and moringa (Moringa oleifera Lamarck) epoxidized oils and develop a new additive package using experimental design for their use as a hydraulic fluid. In the first stage of this work was performed the optimization of the epoxidation process of the oils using fractional experimental design 24-1 , varying the temperature, reaction time, ratio of formic acid and hydrogen peroxide. In the second step was investigated the selectivity, thermodynamics and kinetics of the reaction for obtaining the two epoxides at 30, 50 and 70 °C. The result of the experimental design confirmed that the epoxidation of passion fruit oil requires 2 hours of reaction, 50 °C and a ratio H2O2/C=C/HCOOH (1:1:1). For moringa oil were required 2 hours reaction, 50 °C and a ratio of H2O2/C=C/HCOOH (1:1:1.5). The results of the final conversions were equal to 83.09% (± 0.3) for passion fruit oil epoxide and 91.02 (±0,4) for moringa oil epoxide. Following was made the 23 factorial design to evaluate which are the best concentrations of corrosion inhibitor and anti-wear (IC), antioxidant (BHA) and extreme pressure (EP) additives. The bio-lubricants obtained in this step were characterized according to DIN 51524 (Part 2 HLP) and DIN 51517 (Part 3 CLP) standards. The epoxidation process of the oils was able to improve the oxidative stability and reduce the total acid number, when compared to the in natura oils. Moreover, the epoxidized oils best solubilized additives, resulting in increased performance as a lubricant. In terms of physicochemical performance, the best lubricant fluid was the epoxidized moringa oil with additives (EMO-ADI), followed by the epoxidized passion fruit oil with additives (EPF-ADI) and, finally, the passion fruit in natura oil without additives (PFO). Lastly, was made the investigation of the tribological behavior under conditions of boundary lubrication for these lubricants. The tribological performance of the developed lubricants was analyzed on a HFRR equipment (High Frequency Reciprocating Rig) and the coefficient of friction, which occurs during the contact and the formation of the lubricating film, was measured. The wear was evaluated through optical microscopy and scanning electron microscopy (SEM). The results showed that the addition of extreme pressure (EP) and anti-wear and corrosion inhibitor (CI) additives significantly improve the tribological properties of the fluids. In all assays, was formed a lubricating film that is responsible for reducing the coefficient of metal-to-metal wear. It was observed that the addition of EP and IC additives in the in natura vegetable oils of passion fruit and moringa did not favor a significant reduction in wear. The bio-lubricants developed from passion fruit and moringa oils modified via epoxidation presented satisfactory tribological properties and shown to be potential lubricants for replacement of commercial mineral-based fluids.

Desenvolvimento e avaliação tribológica de emulsão O/A a partir de óleo vegetal epoxidado para aplicação em fluídos de corte

The cutting fluids are lubricants used in machining processes, because they present many benefits for different processes. They have many functions, such as lubrication, cooling, improvement in surface finishing, besides they decreases the tool wear and protect it against corrosion. Therefore due to new environment laws and demand to green products, new cutting fluids must be development. These shall be biodegradable, non-toxic, safety for environment and operator healthy. Thus, vegetable oils are a good option to solve this problem, replacing the mineral oils. In this context, this work aimed to develop an emulsion cutting fluid from epoxidized vegetable oil, promoting better lubrication and cooling in machining processes, besides being environment friendly. The methodology was divided in five steps: first one was the biolubricant synthesis by epoxidation reaction. Following this, the biolubricant was characterized in terms of density, acidity, iodo index, oxirane index, viscosity, thermal stability and chemical composition. The third step was to develop an emulsion O/A with different oil concentration (10, 20 and 25%) and surfactant concentration (1, 2.5 and 5%). Also, emulsion stability was studied. The emulsion tribological performance were carried out in HFRR (High Frequency Reciprocating Rig), it consists in ball-disc contact. Results showed that the vegetable based lubricant may be synthesized by epoxidationreaction, the spectra showed that there was 100% conversion of the epoxy rings unsaturations. In regard the tribological assessment is observed that the percentage of oil present in the emulsion directly influenced the film formation and coefficient of friction for higher concentrations the film formation process is slow and unstable, and the coefficient of friction. The high concentrations of surfactants have not improved the emulsions tribological performance. The best performance in friction reduction was observed to emulsion with 10% of oil and 5% of surfactant, its average wear scar was 202 μm.

Metodologia númerico-experimental para avaliação da espessura de filmes de nitreto de titânio obtidos por processamento a plasma

In recent decades, changes in the surface properties of materials have been used to improve their tribological characteristics. However, this improvement depends on the process, treatment time and, primarily, the thickness of this surface film layer. Physical vapor deposition (PVD) of titanium nitrate (TiN) has been used to increase the surface hardness of metallic materials. Thus, the aim of the present study was to propose a numerical-experimental method to assess the film thickness (l) of TiN deposited by PVD. To reach this objective, experimental results of hardness (H) assays were combined with a numerical simulation to study the behavior of this property as a function of maximum penetration depth of the indenter (hmax) into the film/substrate conjugate. Two methodologies were adopted to determine film thickness. The first consists of the numerical results of the H x hmax curve with the experimental curve obtained by the instrumental indentation test. This methodology was used successfully in a TiN-coated titanium (Ti) conjugate. A second strategy combined the numerical results of the Hv x hmax curve with Vickers experimental hardness data (Hv). This methodology was applied to a TiN-coated M2 tool steel conjugate. The mechanical properties of the materials studied were also determined in the present study. The thicknesses results obtained for the two conjugates were compatible with their experimental data.

Gravidade do olho seco em pacientes internados em unidade de terapia intensiva: análise de conceito e construção de definições

Dry eye syndrome is a multifactorial disease of the tear film, resulting from the instability of the lacrimal functional unit that produces volume change, up or tear distribution. In patients in intensive care the cause is enhanced due to various risk factors, such as mechanical ventilation, sedation, lagophthalmos, low temperatures, among others. The study's purpose is to build an assessment tool of Dry Eye Severity in patients in intensive care units based on the systematization of nursing care and their classification systems. The aim of this study is to build an assessment tool of Dry Eye Severity in hospitalized patients in Care Unit Intensiva.Trata is a methodological study conducted in three stages, namely: context analysis, concept analysis, construction of operational definitions and magnitudes of nursing outcome. For the first step we used the methodological framework for Hinds, Chaves and Cypress (1992). For the second step we used the model of Walker and Avant and an integrative review Whitemore seconds, Knalf (2005). This step enabled the identification of the concept of attributes, background and consequent ground and the construction of the settings for the result of nursing severity of dry eye. For the construction of settings and operational magnitudes, it was used Psicometria proposed by Pasquali (1999). As a result of context analysis, visualized from the reflection that the matter should be discussed and that nursing needs to pay attention to the problem of eye injury, so minimizing strategies are created this event with a high prevalence. With the integrative review were located from the crosses 19 853 titles, selected 215, and from the abstracts 96 articles were read in full. From reading 10 were excluded culminating in the sample of 86 articles that were used to analyze the concept and construction of settings. Selected articles were found in greater numbers in the Scopus database (55.82%), performed in the United States (39.53%), and published mainly in the last five years (48.82). Regarding the concept of analysis were identified as antecedents: age, lagophthalmos, environmental factors, medication use, systemic diseases, mechanical ventilation and ophthalmic surgery. As attributes: TBUT <10s, Schimer I test <5 mm in Schimer II test <10mm, reduced osmolarity. As consequential: the ocular surface damage, ocular discomfort, visual instability. The settings were built and added indicators such as: decreased blink mechanism and eyestrain.

O figurino na narrativa dos filmes de Guel Arraes: O Auto da Compadecida (2000) e O Bem Amado (2010)

This research focuses on the course of Guel Arraes, moviemaker, and picks two movies for analysis: O Auto da Compadecida (2000) and O Bem Amado (2010), as well as their costumes. The focus on the costume is based on Semiology and aims to decode the meanings that stem out of the clothes. Three of the movies characters will have their costumes analyzed based on Roland Barthes’ theory, mainly considering semiology elements (language and speech), (significant and meaning) and (system and syntagma). The influence of the Armorial movement into the movie O Auto da Compadecida and the Kitsch aesthetic in O Bem Amado deserve consideration, aside from the study on costumes function within narrative, supported by Roland Barthes’ structural analysis of the narrative. We sought to highlight the balance between characters’ lines and the image of the costumes in the movies. Adding to the study on how costumes strongly accounts to narrative, we observed characteristic traits of director and scriptwriter Guel Arraes present in his works, which are the northeastern man identity, a presentation of the Northeast and popular comedy. We believe that his choices when creating and his life influences are not separate from one another. Our research was movie-appraisal centered and had a thorough investigation all over language. The main considerations are supported by the following theories: Barthes (2007), Figueirôa and Fechine (2008), Moles (2001), Stuart Hall (2005) and Mikhail Bakhtin (2013).

Concentração do óleo de girassol em compostos insaturados utilizando destilação molecular

Vegetable oils are characterized as important raw materials in the supplying of natural substances of interest pharmaceutical, food and cosmetic industry. Sunflower oil stands out for its important composition present in unsaturated fatty acids such as oleic acid (C18:1) and linoleic (C18:2), responsible for many health benefits. The main objective of this study is obtain enriched fractions in unsaturated compounds from refined sunflower oil. The oil used in this study was characterized by the determination of some properties, like iodine number, acid number and viscosity. A transesterification was done to transform the triglycerides into their corresponding methyl esters of fatty acids. These was submitted the molecular distillation process, for present as an efficient alternative to separation and purification of these substances, using high vacuum and low temperatures. Of the esters fractions that was obtained, were analyzed by gas chromatography. The experimental design technique was used to evaluate the influence of the temperature variation of evaporation and condensation system on the percentage obtained residue. The evaporator temperature proved to be the most influential variable on the studied response. The optimized conditions for the answer was studied at 100 °C for evaporator temperature and 10 °C for the condenser temperature. The graph of "split ratio" showed that for the lowest flow feed (1 mL/min) and higher evaporator temperature (110 °C) was obtained in the largest fraction of distillate. It also used the study of the influence of evaporator temperature on the concentration of unsaturated compounds. The best operating conditions for temperature was 90 °C reached 82.21 % of unsaturated compounds. Elimination curves of the unsaturated compounds present in the distillate stream were obtained. The simulation results of the molecular distillation process of sunflower oil showed the concentration profiles for three different feed flow rates. The speed, temperature and thickness profiles of the liquid film were obtained. The speed of the film increases as the fluid flows through the walls of the evaporator, reaching a maximum on length of 0.075 m. The film thickness decreases on the route, since many compounds are volatilized. The result of the temperature profile had to be consistent with the literature reproduced, being constant after reaching the maximum operating temperature in the length of 0.15 m. This study allowed characterizing and focusing, through experimental analysis, unsaturated compounds and observing the sunflower oil´s behavior through process simulation.
