With the growing interest in the issue of reducing powerconsumption in electricity applications, energy-saving devises and the problem of their operation gains more attention. The increase in the utilization of energy-saving lamps, especially LED lamps, leads to the wide interest in their influence on the power system. The impact of discussed devices on the voltage and current in the grid must be thoroughly studied before launching devices into the market. The studies undertaken on the LED lamps present in a wide range the issue of harmonic emission from lamps and their influence on power quality. Due to many anufacturing technologies, different LED devices can have various effects on the utility. It is significant to carry out researches concerning the adverse effects of energy-saving lamps in order to utilize devices that meet certain requirements which are set by the international commissions.

This thesis will explore ideas relating to the engagement of man and nature by promoting the experiences of contemplation and fellowship. The focus will be an urban academic retreat facility to provide an escape from distraction of typical modern urban life. Set within the historic Washington D.C. neighborhood of Georgetown, Dumbarton Oaks is an active academic research institution The Institute is holistically designed; architecture integrated with its surrounding landscape The Institute selects diverse scholars to think, live, and commune within the facility and landscape for up to two years. This thesis will use the existing site, themes, and history of Dumbarton Oaks as a launching point to explore the relationship between architecture, man, and landscape. A proposal to relocate the Fellows residences and reorganize the western edge of the site will help reactivate this forgotten piece of the site realize its potential.

Safety in civil aviation is increasingly important due to the increase in flight routes and their more challenging nature. Like other important systems in aircraft, fuel level monitoring is always a technical challenge. The most frequently used level sensors in aircraft fuel systems are based on capacitive, ultrasonic and electric techniques, however they suffer from intrinsic safety concerns in explosive environments combined with issues relating to reliability and maintainability. In the last few years, optical fiber liquid level sensors (OFLLSs) have been reported to be safe and reliable and present many advantages for aircraft fuel measurement. Different OFLLSs have been developed, such as the pressure type, float type, optical radar type, TIR type and side-leaking type. Amongst these, many types of OFLLSs based on fiber gratings have been demonstrated. However, these sensors have not been commercialized because they exhibit some drawbacks: low sensitivity, limited range, long-term instability, or limited resolution. In addition, any sensors that involve direct interaction of the optical field with the fuel (either by launching light into the fuel tank or via the evanescent field of a fiber-guided mode) must be able to cope with the potential build up of contamination-often bacterial-on the optical surface. In this paper, a fuel level sensor based on microstructured polymer optical fiber Bragg gratings (mPOFBGs), including poly (methyl methacrylate) (PMMA) and TOPAS fibers, embedded in diaphragms is investigated in detail. The mPOFBGs are embedded in two different types of diaphragms and their performance is investigated with aviation fuel for the first time, in contrast to our previous works, where water was used. Our new system exhibits a high performance when compared with other previously published in the literature, making it a potentially useful tool for aircraft fuel monitoring.

The evolution of knowledge and technology in recent decades has brought profound changes in science policy, not only in the countries but also in the supranational organizations. It has been necessary, therefore, to adapt the scientific institutions to new models in order to achieve a greater and better communication between them and the political counterparts responsible for defining the general framework of relations between science and society. The Federationon of Scientific Societies of Spain (COSCE, Confederacin de Sociedades Cientficas de Espaa) was founded in October 2003 to respond to the urgent need to interact with the political institutions and foster a better orientation in the process of making decisions about the science policy. Currently COSCE consists of over 70 Spanish scientific societies and more than 40,000 scientists. During its twelve years of active life, COSCE has developed an intense work of awareness of the real situation of science in Spain by launching several initiatives (some of which have joined other organizations) or by joining initiatives proposed from other groups related to science both at the Spanish level and at the European and non-European scenarios.

This project aims at describing the use of Action Research in the development of more structured assessment practices in Early Childhood Portuguese contexts. The teacher had always observed young learners activities and progress, and registered them in the form of critical incidents. This reflective process structured through this type of narratives helps tune the Class Curriculum firstly designed without much knowledge about the kids and so, difficultly responding to their specific needs and interests. The results achieved suggest kids become better prepared to face further education and life. Being early childhood assessment felt by most Portuguese kindergarten teachers as an innovative procedure, the project was seen as the launching of roots for new practices.

La presente investigacin propone un anlisis sobre la crisis poltica de Crimea en 2014 a partir del influjo que las migraciones desde Rusia han tenido en la historia reciente. As, a partir de la evaluacin de algunos de los momentos de inmigracin ms representativos en los ltimos dos siglos (1860, 1928 y 1991) se vincula el proceso de construccin de la identidad de los inmigrantes -transversal en diferentes periodos histricos en Crimea- con el desarrollo de los eventos de 2014. Lo anterior permite identificar un cierto legado de la migracin hacia Crimea en el desarrollo de la crisis, cuyo resultado principal ha sido la anexin de facto de Crimea a Rusia. sta no habra sido posible sin el particular nimo de afinidad con la idea de Rusia o Russianness- de la mayora de los habitantes de la pennsula, cuya presencia en la regin se explica en parte, a travs de los procesos migratorios antes descritos.

A Casa Grande de Romariges ter sido erguida em 1700 em Romariges, no concelho de Paredes de Coura, em torno da construo da capela de Nossa Senhora do Amparo, conformando a Quinta do Amparo. Ter servido de cenrio literrio a uma das mais simblicas obras do escritor Aquilino Ribeiro A Casa Grande de Romariges, escrita entre 1950 e 1957, ano da sua publicao. A estrutura arquitectnica foi classificada como Imvel de Interesse Pblico em 1986, atribuio que, apesar de demonstrar a preocupao de proteger e conservar este legado histrico e arquitectnico, ainda no derivou em nenhum estudo rigoroso sobre a sua evoluo morfolgica instrumento fundamental para a coerncia de futuras intervenes neste lugar. Com base nas constantes descries na obra de Aquilino Ribeiro, e do seu confronto com a documentao histrica entretanto encontrada (escrita e grfica, em grande parte indita), este trabalho de investigao prope o desenho da evoluo morfolgica da casa ao longo dos tempos, bem como a enunciao da influncia deste solar para a organizao social, cultural e econmica da aldeia de Romariges. Procura, enfim, e num sentido mais lato, indagar sobre a utilidade de um documento literrio para o lanamento de hipteses no contexto de uma investigao arquitectnica, consubstanciadas pela posterior comprovao atravs de fontes primrias; ABSTRACT: A Casa Grande de Romariges (The Great House of Romariges) was erected in early XVIII century, in Romariges, Paredes de Coura, nearby the chapel of Nossa Senhora do Amparo, the chosen name for the villa Quinta do Amparo. This house and villa has been the literary scene of one of the most remarkable works of the writer Aquilino Ribeiro (1885C1963) A Casa Grande Romariges, written between 1950 and 1957, the year of its publication. In 1986, the architectural structure is classified as cultural heritage by the Portuguese state but, despite the meaningful idea of preservation and protection of the historical legacy and architecture, there has not been an initiative to study its morphological evolution and architectural relevance key tool for future and consistent interventions in such rich and particular scenario. Based on descriptions that can be found in the work of Aquilino Ribeiro, and supported with historical documentation research (both written and graphic, mostly unpublished), this work suggests the design of the morphological evolution of the house over the years, together with the construction of its influence on social, cultural and economic organization of the village of Romariges. In a broader sense, this work intends to inquire about the usefulness of a literary document for launching assumptions in the context of an architectural research, substantiated by further evidence through primary sources.
