Considerado una verdadera lección de cine, ya que es una película que se refiere al propio arte cinematográfica, La ventana indiscreta (Rear Window), dirigida por Alfred Hitchcock en 1954, tuvo como base para el guión de John Michael Hayes el cuento “Tenía que ser un asesinato” (“It had to be murder”, 1942), de Cornell Woolrich. Reconocido como uno de los mayores escritores del género policial noir, Woolrich profesaba la “poética del fracaso, [...] conduciendo gradualmente la angustia de la víctima al centro del cuadro, en contraste con la indiferencia mecánica de una sociedad que no se molestaba con su suerte”. (OLIVA, 2003, p.116- 7). La película tuvo un gran éxito de público y crítica, pero esto no había ocurrido con el cuento, que solo se hizo conocido después de su adaptación para el cine. El propósito de este trabajo es realizar un análisis comparativo entre los dos textos, subrayando los siguientes aspectos: 1) la caracterización del género noir (cuando la investigación ya no es un juego para mentes refinadas, como había sido en la narrativa policial clásica) y del suspense (narrativa de tensión que se caracteriza por el aplazamiento de la resolución del enigma), tanto en la narración literaria como en la película; 2) la autorreferencialidad en la película y en el cuento mediante el uso de la metaficción; 3) el problema de la transposición del foco en primera persona de la narrativa para el cine; 4) los diferentes desenlaces, señalando en qué medida indican visiones del mundo también divergentes.

Ocular surface diseases are often diagnosed in brachycephalic dogs. The ophthalmic parameters of the Shih Tzu dogs are evaluated in this study since this breed is among the most commonly affected by these diseases. In this study, ophthalmic parameters of this breed were partly studied under physical restraint. Schirmer tear test, breakup time test, aesthesiometry, biomicroscopy, non-contact specular microscopy, laser flaremetry, applanation tonometry, ultrasonography and ophthalmoscopy were carried in 48 eyes of 24 male and female dogs, aged from two to four years, weighing between 5 and 10kg. All dogs were from a breeding kennel. Descriptive statistics were applied to the data. Mean and standard error for Schirmer tear test was 26.145±0.803mm min-1; breakup time test, 13.668±0.538s; and aesthesiometry, 2.395±0.071cm. The biomicroscopy evaluation showed that 70.83% of the eyes had medial entropion; 42% caruncular trichiasis; 33% distichiasis, 27% mild paracentral corneal opacity; and 13% corneal melanosis. Mean and standard error for endothelial cell density was 2221.591±20.161cells mm-2; endothelial cell hexagonality, 63.770±1.805%; endothelial cell area, 451.895±4.179mm2; central corneal thickness, 0.490±0.007 mm; laser flaremetry, 1.720±0.216PC ms-1; applanation tonometry, 16.118±0.460mmHg; axial length, 20.255±0.134mm; lens thickness, 6.624±0.031mm; anterior chamber, 4.064±0.109mm; and vitreous chamber, 9.565±0.054mm. Ophthalmoscopy findings were not different from previous reports for other breeds. The results showed that the ophthalmic Shih Tzu parameters did not differ from other breeds according to data in the literature, except for the breakup time and Cochet-Bonnet aesthesiometry.

Participei do projeto de extensão Grupo de Formação: Diálogo e Alteridade, constituído por graduandos do curso de Pedagogia. Esse projeto está articulado a um curso de extensão, oferecido para professoras coordenadoras, vice-diretoras e coordenadoras pedagógicas do município de Rio Claro, e do qual também participam os graduandos. O curso, ao longo de dois anos (2011-2012), teve a pretensão de promover a sensibilização do olhar através do uso dos filmes. Em virtude das experiências vividas durante o curso e da grande presença das tecnologias em nossa sociedade, a presente pesquisa objetivou compreender quais as contribuições das mídias e dos filmes no ambiente escolar, tanto em relação ao trabalho pedagógico com os alunos como nos processos de formação continuada de professores e gestores. A partir de uma pesquisa bibliográfica realizada nos Anais da ANPEd (Associação Nacional de Pós-Graduação e Pesquisa em Educação) e do ENDIPE (Encontro Nacional de Didática e Prática de Ensino) sistematizei a produção científica que trata dos filmes no contexto educacional. Na busca por compreender quais as contribuições dos filmes para a formação das educadoras que participaram do referido curso, foi desenvolvida uma pesquisa documental a partir dos registros da pesquisadora e das escritas produzidas pelas participantes do referido curso. A pesquisa pretende contribuir para a ampliação e socialização das produções científicas acerca da temática

Esse trabalho aborda a forma como os heróis são retratados atualmente no cinema pela indústria cultural e como se dá a divergência em relação aos heróis clássicos dos mitos gregos. O mito grego adotado como parâmetro para comparação e análise é o que narra a trajetória de Ulisses de volta para a ilha de Ítaca. O filme atual sobre o qual se desenvolve o estudo comparativo do herói no cinema é Capitão América - O Priemiro Vingador, adaptação dos quadrinhos da Marvel para o cinema em 2011, pelo diretor Joe Johnston. O mito surge nos começos de toda civilização, sendo visto como uma história sagrada, da qual tomaram parte os deuses ou seres sobrenaturais que participaram desses acontecimentos.

The high perishability of the onion has limited its conservation period and caused great post-harvest losses. The need of consuming fresh products has led the market of minimally processed products to considerably rise. Cut operations during the minimal processing may not only cause important biochemical reactions in the onion tissues, but also affect its sensorial quality, resulting in a drastic reduction in the post-harvest life of the product. In this study the influence of different cut types was assessed on the quality of minimally processed onions. 'Baia Periforme'onions were transported to the laboratory, where they were selected, cleaned, classified, peeled, minimally processed into slices, grated and chopped, and subsequently sanitized for 10 minutes in sodium hypochlorite at 100 mg L-1. The product was kept on polystyrene trays covered with plastic film (PVC) as 80 g portions and conserved in a cold chamber at 5 +/- 1 degrees C and 85 +/- 5% RH, during 6 days. Physical, chemical and physico-chemical assays were carried out. Statistical design was completely randomized with 3 treatments and 3 replications (plot group) and 5 replicationss for the control group. For sensorial analysis (aspect and smell), 10 replications were used. To compare means, Tukey test at 5% significance was adopted. During the refrigerated conservation, sliced onions kept more stable levels of soluble solids, titratable acidity, total sugars, reducing and non-reducing sugars. The grated onion was superior considering the sensorial characteristics, indicating that the cut types interfered in these features and the grated onion was more accepted by evaluators.

O caqui apresenta uma safra curta, sendo necessário estender seu período de comercialização utilizando técnicas adequadas de armazenamento. O objetivo deste trabalho foi avaliar o uso da radiação gama na qualidade pós-colheita de caquis 'Giombo' destanizados. Frutos colhidos meio-maduros e com aproximadamente 50 % da coloração verde, foram destanizados, acondicionados em bandejas de poliestireno expandido (EPS), revestidas por filme plástico de polietileno de baixa densidade (PEBD) e submetidos à radiação gama (60Co). Os frutos foram armazenados durante 35 dias, sob refrigeração (0±0,5 ºC e 85 ± 0,5% UR). Os tratamentos realizados foram: T1 - 0,0 kGy; T2 - 0,3 kGy; T3 - 0,6 kGy; T4 - 0,9 kGy; T5 - 1,2 kGy. As análises realizadas a cada 7 dias foram: perda de massa, atividade respiratória, teores de sólidos solúveis (SS), ácido ascórbico, acidez titulável (AT) e relação SS/AT. Os frutos submetidos à dose de 0,6 kGy apresentaram o menor percentual de perda de massa e produção de CO2 ao longo do período experimental. Os teores de SS e AT permaneceram estáveis e sem diferenças devido às doses de irradiação aplicadas. Os tratamentos com 0,3 KGy e 0,6 KGy foram os mais eficazes na manutenção da firmeza nos caquis. Nos teores de ácido ascórbico, observou-se redução ao longo do período experimental, sendo os menores valores apresentados para a maior dose de irradiação (1,2 KGy).

Usually organic polymeric diodes are made with a semiconductor layer placed between two electrodes in a sandwich-like architecture, where the electrodes are deposited on the surfaces of a polymeric semiconductor film. This methodology leads to two main problems: i) the polymeric film top surface is rough and irregular, resulting in non-uniform electric field into the device; ii) during the deposition of metallic electrode in the top surface polymeric film, by thermal evaporation, occurs the diffusion of metal atoms into the polymeric film, changing the material electronic structure. Thus, the metal-semiconductor junction is not well defined, which is essential for the production of good quality Schottky diode, which exhibits ideality factor close to the unity and low turn-on voltage. In order to avoid these two problems, in the present research was proposed to manufacture an organic diode with the semiconductor polymeric layer deposited over bimetallic (gold and aluminum) interdigitated electrodes. The doping of the active layer was performed by immersing the device in hydrochloric acid solution with pH 2 during different times in order to promote different doping levels of the semiconductor polymer. Was verified that the proposed diode, which exhibits well-defined metal-semiconductor junction, operates as a Schottky diode, with good ideality factor, 10 ± 3, and low turn-on voltage, 1,2 ± 0,2 V, in comparison with conventional organic polymeric diodes. Contrasting with the ideality factor and turn-on voltage, the diode rectification ratio was obtained as 7, a value lower than the expected for a good organic diode. Was also showed that the diode characteristics were dependent on the semiconductor polymer doping level, and that the diode characteristics were optimized with doping promoted by immersion in the acid solution for times longer than 50 s. Furthermore, as was showed that the diodes properties are dependent on the semiconductor...

The sol-gel process is a technique based on the hydrolysis and polycondensation of metal alkoxides have been investigated as an alternative for the preparation of vitreous or glassceramic materials, for allowing the obtaining of high-purity materials at low temperatures, and to obtain hybrid materials with different compositions. When ORMOSILs are doped with nanoparticles, are called nanocomposites, and its functionality arises when electrons confined in scale three-dimensional structures near zero are excited. In principle, such materials exhibit discrete energy level, with peaks in the absorption spectrum. Therefore, the glasses doped semiconductor nanocrystals are important candidates for the preparation of optical filters with sharp cut-off, and are being exploited commercially for coloring glasses. This study evaluates the optical properties presented by hybrid films of silica doped with copper nanoparticles. The matrix was prepared using the alkoxides 3-glycidoxypropyltrimethoxysilane (GPTS) and tetraethylorthosilicate (TEOS) doped with Cu2O and hydrolyzed under reflux conditions in two different acidic conditions (HCl and HBr). After thermal treatment at temperatures between 100 °C and 170 °C and/or under the action of commercial black light radiation, CuCl and CuBr present in the hybrid film are transformed into nanoparticles of CuCl or CuBr. The UV-VIS absorption identified the absorption bands, and its variation

This work shows the preparation and characterization of the new nanocomposites based on fibroin and biocellulose. Bacterial cellulose (BC) is an exopolysaccharide produced by bacteria of the genus Gluconacetobacter, which it has identical chemical structure of the cellulose from plants and it has gained attention in the field of research for its unique properties as excellent mechanical properties when dry and hydrated , higher capacity of water retention, moldability , biodegradability and excellent biological affinity . Silk fibroin (SF) is a structural protein present in the cocoon of the silkworm, Bombyx mori, has been identified as suitable for developing optical devices, tissue engineering application, enzyme immobilization, controlled release drug agent biopolymer. Silk fibroin/bacterial cellulose nanocomposite films were prepared impregnating different cellulose charges (0.5 %, 1.0 %, 1.5 %, 2.5 %, 5.0 % and 10.0 %) weight/weight. According mechanical tests and water and Paynes's cup permeability showed that SF/BC 1% nanocomposite has the most relevant results. Poliethylenoglicol (PEG) containing SF films improved optical and mechanical properties when compared to pristine SF film. New SF/BC nanocomposites could be applied in Medicine, as biodegradable packaging and flexible substrates for OLEDs.

Once petroleum is na exhaustible source of energy, alternative fuels are having more prominence. A much discussed option for replacing fossil fuels is the use of biofuels derived from oils or fats, especially biodiesel. The biodiesel preparation is through a reaction named transesterification, a reaction of triglycerides with a short chain alcohol with a catalyst, producing a mixture of fatty acid esters and glycerol. According to ANP (National Petroleum Agency) specifications, biodiesel can have contaminants due to the catalyst or oil used on its synthesis, such as phosphorus, wich can damage the catalytic converter and cause significant increase in the particles emission. This project aims to develop na alternative method using chemically modified electrodes with iron nanoparticles for determination of phosphorus in biodiesel. For the formation of the iron nanoparticles film on the surface of a glassy carbon electrode, was used a iron sulfate solution. The film was formed after 10 successive cycles, with a scanning speed of 50 mV s-1 and a potential range of -0,9 to -1,25 V. To reduce possible oxides on the surface and activate the electrode, it has been subjected to a cathodic polarization with a potential of -1,25 V for 15 minutes in a sodium hydroxide solution. In cyclic voltammograms obtained in the study of the speed of scanning, there is an increase in the intensity of the anodic and cathodic current peaks. The cathodic peak current varied linearly with the square root of scan rate, showing that the electrode is controlled by diffusion. After successive additions of phosphate there is a linear variation in the current peak in the concentration range of 1,0 x 10-7 a 1,0 x 10-6 mol L-1. To determine if the concentration of phosphorus in real sample, the method of adding standard was used by adding aliquots of phosphate ions in the solution containing soy biodiesel extracted with ....
