Trabalho de Projeto apresentado à Escola Superior do Instituto Politécnico de Castelo Branco para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Música – Área de Especialização em Piano. ; El objetivo principal de mi trabajo lo constituye el análisis de la Sonata para piano Sz. 80 (1926), pero representa en igual medida un acercamiento a la extraordinaria personalidad de su creador, el compositor húngaro Bela Bartok. Existe muchísima información con respecto a su obra, a su desarrollo, sus influencias, sus innovaciones, sus fuentes de inspiración, la estructura de sus composiciones etc. pero no muchos datos sobre la personalidad del hombre Bela Bartok, que resulta cada vez más fascinante a medida que se nos revelan los detalles referentes a su tormentosa existencia. Por estos motivos comenzaré mi estudio con su biografía, que está unida de manera intrínseca a su obra, ya que se podría decir que la vida personal de Bela Bartok se ha identificado, durante toda la existencia del compositor, con su música. Después de repasar las principales etapas de su vida, empezando por su juventud, pasando por la ansiedad provocada por los extraordinarios cambios sociales y políticos que ocurrieron en la sociedad en la que vivía después de la primera guerra mundial, analizando los motivos por los que tuvo que auto-exiliarse en América como consecuencia de la segunda guerra mundial, acabaré presentando sus últimos años de vida en suelo americano, su lucha contra la cruel enfermedad que padecía y, finalmente, su muy temprana muerte. Haré también una presentación de sus principales obras escritas a lo largo de su vida, tanto en Europa como en América, en los últimos años de su vida. Seguiré después presentando y analizando musicalmente y formalmente la Sonata para piano Sz 80 compuesta en 1926, análisis precedido por unas consideraciones sobre la escritura pianística de Bela Bartok. Al final del análisis de cada movimiento añadiré unas consideraciones personales sobre las principales dificultades técnicas que se pueden encontrar en cada uno de los tres movimientos de la sonata. Me ha parecido interesante incluir en este trabajo un análisis comparativo de dos interpretaciones de la sonata para piano pertenecientes a dos reputados pianistas, muy distintos uno del otro en sus formas de tocar y de interpretar la música de Bartok; ellos aportan, por estos mismos motivos, riqueza y universalidad a la música de Bela Bartok. ; Abstract: The main purpose of my work is the analysis of the Sonata for piano Sz. 80 (1926), but it represents an approach to the extraordinary personality of its creator, the Hungarian composer Bela Bartok in equal measure. There is a lot of information with respect to their work, their development, their influences, their innovations, their sources of inspiration, the structure of his compositions etc. but not many data on the personality of the man Bela Bartok, which become increasingly more fascinating as will reveal the details of his stormy existence. That`s why I`ll begin my study with his biography, which is linked intrinsically to its work, since it could be said that the personal life of Béla Bartók has been identified, throughout the existence of the composer, with his music. After reviewing the main stages of his life, beginning with his youth, through the anxiety caused by the extraordinary social and political changes that took place in the society in which he lived after the first world war, analyzing the reasons of his self-exile in America as a result of the second world war, I will finish this work presenting his last years of life on American soil, his struggle against the cruel disease that suffered and, finally, his early death. I`ll make also a presentation of his main works written throughout his life, both in Europe and in America, in the last years of his life. I will continue later presenting and analyzing musically and formally Sz 80 piano Sonata composed in 1926, analysis preceded by a few considerations on the piano writing of Béla Bartók. At the end of each movement, I will add some personal considerations on the main technical difficulties that can be found in each of the three movements of the sonata. I found interesting to include in this work a comparative analysis of two interpretations of the piano sonata that belong at two reputed pianists, very different one from the other in its forms of perform the Bartók music; they provide, for these same reasons, richness and universality to the music of Béla Bartók.

The technological process of obtaining the compound feeds involves the mixing of the milled cereals in the mills of the work installation with protein flours, mineral salts and vegetable oils. During the activities of grinding cereals and obtaining granules of finished product, it can be detached fine particles which forming the dust that is released in the air. This article analyzes the technological process for the preparation of compound feeds with accent on the stages of grinding, granulation and homogenization of the finished product, for study the problems who can appear due to the eliminated dust in the air by the working installations. The measurements effectuated attest the efficiency of the use of special filtres and automatized control systems of dust concentrations according to the pollution norms imposed by the European Union in order to protect the environment.

The long term objective of Romanian economy is that of putting the bases of a real market economy, which will integrate in the structures of the European Union and will respect the Community provisions. This way, even for the industry production sector from the zoo-technical domain, reaching of this objective means the endowment with modern, efficient equipment, with a higher level of mechanization, automation and computerization, with higher productivity and lower specific consumptions. In this article is made an analysis of dust concentration in flue gases emitted of a Compound Feed Factory (CFF), regarding the conformity to European norms concerning the quality of the environment.

Remote sensing is a powerful tool used in biometeorology to study the interactions between the atmosphere and living organisms, particularly plants. Through satellite-based sensors, researchers can observe and analyze a range of biophysical parameters related to vegetation, such as leaf area index, biomass, vegetation cover, and land surface temperature. This data can be used to estimate plant growth, productivity, and water use efficiency, as well as monitor environmental conditions, such as drought, heat stress, and air pollution. Remote sensing is used in the development of crop models for agricultural management and to study the impact of climate change on plant communities and ecosystems. By tracking changes in vegetation cover and productivity, as well as changes in phenology, remote sensing helps researchers identify optimal planting times, irrigation schedules, and predict crop yields.
