La Escuela Oficial de Cine como creadora de maestros: Juan Julio Baena, Luis Enrique Torán y Luis Cuadrado, los primeros profesionales de la luz realista del cine español

Este artículo tiene como objetivo fundamental mostrar cómo el Instituto de Investigaciones y Experiencias Cinematográficas (IIEC) fue, desde finales de los años cuarenta hasta mediados de los años sesenta, el creador de una escuela de maestros de la luz y cómo la enseñanza de estos nuevos métodos de iluminación traspasó las fronteras de las aulas y marcó el inicio del Nuevo Cine Español. Para ello se han revisado las principales fuentes bibliográficas de los que consideramos fueron los primeros maestros de fotografía que dio el IIEC: Juan Julio Baena, Luis Enrique Torán y Luis Cuadrado, y se ha realizado un aná­lisis fílmico de la primera obra audiovisual de cada uno en la que se instaura un ambiente de renovación, un cambio estético y el uso de unas técnicas fotográficas más realistas. Así mismo, hemos observado cómo la nueva docencia de la fotografía fue trasladada a otras personas que también llegaron a ser maestros y no estudiaron en el IIEC. Por tanto, se trata de una escuela generadora de maestros tanto dentro como fuera de sus aulas.

Empreendedorismo e Cultura: um estudo sobre empreendedores estrangeiros no RN

This present study analyses the relationship between national culture and entrepreneurship, in order to contribute in understanding the impact and the influence of Brazilian culture under the business practices of foreign entrepreneur on the tourism area of Rio Grande do Norte state. Researchers in entrepreneurship field, such as Schumpeter (2005), Weber (2006), McClelland (1972), Murphy, Liao, Welsch (2006), Peyrefitte (1999), Blanchflower (1988), Filion (2000), among others, and in the national culture, high-lighting Caldas and Woods (1999), Hofstede (1997) and Barros and Prates (1996), are put together to create a starting point to this present research, that reaches out for a differential approach, in order to create a correlation between Brazilian culture and the foreign entrepreneur, who chose Rio Grande do Norte state to live and invest. It was observed that in the case of the Switzerland entrepreneur, where the cultural difference is more strong, either in Hofstede's perspective than in Brazilian s authors, the management practices are more negatively affected. The rationalization adopted by the entrepreneur and the employee s logic are in battle in a day-to-day operation of the company. In the case of the Argentinean entrepreneur, the cultural difference exists, but it does not impact as much, because of her personal characteristics and the similarities of Latin culture than surfaces the differences. Finally, this study showed the necessity of analyzing the enterprising regarding the cultural issue, in a way to highlight the different rationalities in different atmospheres where it is practiced the enterprise

The influence of photon excitation and proton irradiation on the luminescence properties of yttria stabilized zirconia doped with praseodymium ions

Lanthanide doped zirconia based materials are promising phosphors for lighting applications. Transparent yttria stabilized zirconia fibres, in situ doped with Pr3+ ions, were grown by the laser floating zone method. The single crystalline doped fibres were found to be homogeneous in composition and provide an intense red luminescence at room temperature. The stability of this luminescence due to transitions between the 1D2 → 3H4 multiplets of the Pr3+ ions (intra-4f2 configuration) was studied by photo- and iono-luminescence. The evolution of the red integrated photoluminescence intensity with temperature indicates that the overall luminescence decreases to ca. 40% of the initial intensity at 14 K when heated to room temperature (RT). RT analysis of the iono-luminescence dependence on irradiation fluence reveals a decrease of the intensity (to slightly more than ∼60% of the initial intensity after 25 min of proton irradiation exposure). Nevertheless the luminescence intensity saturates at non-zero values for higher irradiation fluences revealing good potential for the use of this material in radiation environments.

Leave a light on – Terracotta lamps from Agia Paraskevi of Arachamitai, from the Classical period until Roman times

This thesis deals with terracotta lamps found at the archaeological site of Agia Paraskevi of Arachamitai during the years 2010–2014. The research questions are: What kind of lamps were used on the site and when? For what purposes were the lamps used? Where were they manufactured? In order to address these questions, a total of fifty lamps have been chosen to form the body of research material. To answer the first research question, a typology for these lamps has been created with twenty-one types and one variant, after examining various lamp typologies and previous publications. The find contexts and distribution of the lamps are both examined to test the dates for the different lamp types gathered from other publications, and to answer the question on what purposes the lamps were used on the site. Visual observation of the clay of the lamps and information on clay materials from other sites are both examined to determine the lamps' origins. The lamps in this study date from the 5th century BC to the 2nd century AD. The find contexts allow the dating of the lamps according to the other publications, but suggestions of more site-specific dates are given to some lamps. The distribution of the lamps indicates that while most were used for everyday lighting at the sanctuary, some may have had ritual connections. Most of the lamps were manufactured locally or at a nearby Arcadian site. Few lamps can be regarded as imports.

Abordagem quantitativa do coolhunting ao sector da iluminação

Vivemos um momento de crise, com profundas mudanças globais, a nível político, económico-social e tecnológico, que afetam todos os setores de atividade de forma transversal. A iluminação não está de forma alguma imune a estas alterações. A sobrevivência das empresas requer uma atenção permanente às mudanças do mercado. As formas tradicionais de olhar os mercados e os consumidores, podem tornar-se insuficientes face à rapidez com que as mudanças ocorrem. Algumas metodologias heterodoxas de abordagem ao mercado, como é o caso do coolhunting, começam a ser olhadas de outra forma. Uma das limitações apresentadas na literatura relativamente ao coolhunting é o peso da intuição ou de outras metodologias subjetivas nos resultados obtidos. Numa altura de escassez de recursos, poderá ser problemático para um empresário apostar recursos sem poder contar com números na tomada de decisão, mas apenas em imagens e conceitos. Partindo dos resultados qualitativos de um relatório de coolhunting, este Projeto de Mestrado propõe-se criar e testar uma metodologia que seja capaz de fazer uma análise quantitativa desses resultados de forma que seja possível responder à questão: num determinado mercado que conceitos-chave poderão ter um maior potencial de difusão? Um conjunto de países, de entre os chamados BRIC e os PALOP, foram escolhidos para testar a metodologia. Foi assim possível obter valores em forma de índice comparativo desse potencial de difusão. A metodologia utilizada tem ainda um grande potencial de aperfeiçoamento. Na parte final é apresentada um conjunto de pistas com este objetivo.

Efficient daylighting approach by means of light-shelve device adequate for habitat program in Aarhus City

The concepts of light shelves consist of windows that have face towards the sun, which receive a vast quantity of energy that could be used for healthy day lighting. This paper debates a main assessment, investigates the optimization of daylight requirement by means of light shelves system. An experimental test was carried out assessing the measurements and lighting simulations of a model of a building in order to elucidate the characteristics of indoor lighting. Light shelf is an architectural element that permits daylight to enter deep into a building. It constitutes an optimal solution for an incorrect building orientation and less sunny days. The essential objective of this study is to highlight the vital role of light shelves in residential buildings in northern Europa where the requirement is to improve the daylight in the interior functional spaces. The main objects of this paper are to investigate the effect of daylight in the interior functional spaces using light shelves, the effect of natural light diffusion in interior space in the period of low daylight season, and glare effect in this field. This paper investigates a procedure for analysing the daylight performance using software habitat function

Role of substrate quality on the performance of semipolar (11 2 - 2) InGaN light-emitting diodes

We compare the optical properties and device performance of unpackaged InGaN/GaN multiple-quantum-well light-emitting diodes (LEDs) emitting at ∼430 nm grown simultaneously on a high-cost small-size bulk semipolar (11 2 - 2) GaN substrate (Bulk-GaN) and a low-cost large-size (11 2 - 2) GaN template created on patterned (10 1 - 2) r-plane sapphire substrate (PSS-GaN). The Bulk-GaN substrate has the threading dislocation density (TDD) of ∼ and basal-plane stacking fault (BSF) density of 0 cm-1, while the PSS-GaN substrate has the TDD of ∼2 × 108cm-2 and BSF density of ∼1 × 103cm-1. Despite an enhanced light extraction efficiency, the LED grown on PSS-GaN has two-times lower internal quantum efficiency than the LED grown on Bulk-GaN as determined by photoluminescence measurements. The LED grown on PSS-GaN substrate also has about two-times lower output power compared to the LED grown on Bulk-GaN substrate. This lower output power was attributed to the higher TDD and BSF density.

Ionisation and discharge in cloud-forming atmospheres of brown dwarfs and extrasolar planets

Brown dwarfs and giant gas extrasolar planets have cold atmospheres with rich chemical compositions from which mineral cloud particles form. Their properties, like particle sizes and material composition, vary with height, and the mineral cloud particles are charged due to triboelectric processes in such dynamic atmospheres. The dynamics of the atmospheric gas is driven by the irradiating host star and/or by the rotation of the objects that changes during its lifetime. Thermal gas ionisation in these ultra-cool but dense atmospheres allows electrostatic interactions and magnetic coupling of a substantial atmosphere volume. Combined with a strong magnetic field , a chromosphere and aurorae might form as suggested by radio and x-ray observations of brown dwarfs. Non-equilibrium processes like cosmic ray ionisation and discharge processes in clouds will increase the local pool of free electrons in the gas. Cosmic rays and lighting discharges also alter the composition of the local atmospheric gas such that tracer molecules might be identified. Cosmic rays affect the atmosphere through air showers in a certain volume which was modelled with a 3D Monte Carlo radiative transfer code to be able to visualise their spacial extent. Given a certain degree of thermal ionisation of the atmospheric gas, we suggest that electron attachment to charge mineral cloud particles is too inefficient to cause an electrostatic disruption of the cloud particles. Cloud particles will therefore not be destroyed by Coulomb explosion for the local temperature in the collisional dominated brown dwarf and giant gas planet atmospheres. However, the cloud particles are destroyed electrostatically in regions with strong gas ionisation. The potential size of such cloud holes would, however, be too small and might occur too far inside the cloud to mimic the effect of, e.g. magnetic field induced star spots.

Medidas de eficiência energética numa indústria cerâmica

O presente relatório resulta de um estágio realizado no âmbito da eficiência energética assente no programa Galp 20-20-20 que tem por génese uma parceria entre a Universidade de Aveiro e a empresa de coberturas cerâmicas, CS – Coelho da Silva S.A. A Fábrica alvo de estudo é uma consumidora intensiva de energia, despendeu no ano de 2013 cerca de 3.768 tep. Devido aos seus processos de cozedura e secagem, apresenta uma elevada dependência de Gás Natural, representando pouco mais de 78% do consumo global da fábrica. Deste consumo de energia térmica, 83% respeita ao forno e os restantes 17% encontram-se alocados ao secador, pelo que as medidas de eficiência energética presentes neste relatório centram-se da redução deste vetor energético. São então propostas três medidas para a redução da dependência deste vetor. A primeira, incide na recuperação de calor residual presente nos gases de exaustão através da instalação de um permutador de calor. Esta medida permite uma redução do consumo na ordem dos 10% e conta com um payback de 2,3 anos resultante de uma economia anual de 150.000 €. Para este estudo foi desenvolvido um modelo dinâmico em excel que permite a simulação de diversos cenários. São também propostas mais duas intervenções que incidem na alteração do circuito térmico. Estas medidas têm um impacte mais reduzido no que respeita ao percentual de redução energético, ambas com menos de 1% de redução do consumo global da fábrica. Contudo são medidas bastante interessantes dada a sua simplicidade e contam com poupanças anuais na ordem dos 6.000 € que resultam num payback inferior a 2 meses. Paralelamente executaram-se dois estudos para a iluminação, o primeiro sugere a instalação de um modelador de tensão que reduz a potência de iluminação em 36%, implicando uma redução da iluminância de cerca de 5%. A redução da potência resulta numa economia energética na ordem dos 0,4% da energia global da instalação. Este equipamento poderá ser adquirido por completo ou em renting. Ao optar pela compra integral, o investimento será apenas ressarcido em 2,8 anos resultante de uma poupança anula de perto de 6.500 €. Caso seja por renting este não tem qualquer custo adicional e as economias monetárias são partilhadas entre a empresa que fornece o equipamento e a CS-Coelho da Silva, S.A. Por fim é sugerida a substituição de parte da iluminação atual da fábrica por tecnologia LED, com esta medida reduz-se o consumo global em 0,76%. Esta medida gera uma economia monetária na ordem dos 11.500 € sendo ressarcida em 2,1 anos.
