Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / The intensification of agricultural production systems is increasing in the current agriculture. In this sense, the simultaneous planting forage to grain crops, constitutes an alternative in the intensification of the production system, which can increase or not the productivity of the main crop, and produce straw for mulching. In order to check the occurrence of changes in the physical properties of the soil and in corn yield and dry matter production due to the corn consortium / forage in two sowing dates, this study was conducted in the experimental area of the Department of Agricultural Engineering of the Federal University of CearÃ. The design was used in a randomized block design in a factorial scheme (3x2) + 1 with four replications, totaling 28 experimental units. The treatments consisted of three forages: Brachiaria, Panicum maximum cv. MombaÃa and Crotalaria spectabilis intercropped with maize in two of fodder sowing dates, between the lines of simultaneous sowing maize (season 1 - E1) and corn leading the V4 stage of corn (season 2 - E2), and the control. The results showed that intercropping maize / forage did not interfere in phytotechnical characteristics of corn, nor in productivity, however produced changes in soil physical properties when the day of sowing in season 1. Despite the changes that have occurred in the soil, they were not sufficient to enhance the productivity of maize, which could possibly be related assessments on only one crop cycle. But when the goal was the production of dry straw, it is concluded that fodder Brachiaria brizantha and Mombasa at the time 1 (E1) are recommended / A intensificaÃÃo dos sistemas de produÃÃo agrÃcola à cada vez maior na atual agricultura. Nesse sentido, o plantio simultÃneo de forrageiras com culturas produtoras de grÃos, constitui em uma alternativa na intensificaÃÃo do sistema de produÃÃo, que poderà incrementar ou nÃo a produtividade da cultura principal, alÃm de produzir palha para cobertura do solo. Com o objetivo de verificar a ocorrÃncia de mudanÃas nas propriedades fÃsicas do solo, bem como na produtividade do milho e produÃÃo de matÃria seca em funÃÃo do consÃrcio milho/forrageiras em duas Ãpocas de semeadura, o presente trabalho foi conduzido na Ãrea experimental do Departamento de Engenharia AgrÃcola da Universidade Federal do CearÃ. Foi utilizado o delineamento em blocos ao acaso, no esquema fatorial (3x2) + 1 com quatro repetiÃÃes, totalizando 28 unidades experimentais. Os tratamentos foram constituÃdos por trÃs forrageiras: Brachiaria brizantha, Panicum maximum cv. MombaÃa e CrotalÃria spectabilis consorciadas com o milho em duas Ãpocas de semeadura das forrageiras, na entrelinha do milho simultÃneo a semeadura (Ãpoca 1 â E1) e na entrelinha do milho no estÃdio V4 do milho (Ãpoca 2 â E2), alÃm da testemunha. Os resultados permitiram concluir que a consorciaÃÃo milho/forrageiras nÃo interferiram nas caracterÃsticas fitotÃcnicas do milho, nem tampouco, na produtividade, porÃm proporcionaram modificaÃÃes nas propriedades fÃsicas do solo quando da realizaÃÃo da semeadura na Ãpoca 1. Apesar das modificaÃÃes ocorridas no solo, as mesmas nÃo foram suficientes em incrementar a produtividade do milho, o que possivelmente pode estar relacionado as avaliaÃÃes em apenas um ciclo da cultura. Jà quando o objetivo foi a produÃÃo de matÃria seca de palha, conclui-se que as forrageiras Brachiaria Brizantha e MombaÃa na Ãpoca 1 (E1) sÃo recomendadas

This study is concerned with the vertical combinations resulting from late sixteenth century cadential formulae and in passages immediately preceding these formulae. The investigation is limited to Masses dating from the last half of the sixteenth century and utilizes compositions from the following composers: Handl, Kerle, Lassus, Merulo, Monte, and Palestrina, Victoria. This study concludes that the progressions I-V-I and I-IV-I appear to be the only two root progressions receiving high enough percentages to be regarded as significant. These percentages are tempered by the fact that I-V-I and I-IV-I may be interpreted as repetitions of standardized cadential formulae found in the sixteenth century. The study also concludes that root motion by fifth accounts for no less than 67.35 per cent of the root movements analyzed during the investigation. The percentage differential between root movement by fifth and root movement by second (the interval receiving the next highest percentage) at no time drops below 40.41 per cent. The evidence indicates that root movement by fifth does account for the majority of the root motion analyzed in final cadential passages of Masses dating from the late sixteenth century. The percentage differential between root motion by second and root motion by third decreases as the chord progressions become longer. None of the differential percentages were judged to be high enough as to merit placing any significance of root motion by second over root motion by third.

For most of the twentieth century, opera singers were not beholden to the ideal physical standard of women dictated by popular culture, but rather focused on serving the music and perfecting their artistry. Unprecedented sociocultural changes throughout the twentieth century exposed the shifting ideals of each generation and how they were promoted through mass media and advertising. This thesis surveys the time period of the 1890s to the present day for the purpose of analyzing cultural trends, philosophies and technologies that shaped the century. Societal pressure to make the body a project and the focus of one's own intense attention now reflects back onto the opera stage where audience members expect to see what society has dictated to be an acceptable female form. Artistic and stage directors are influenced by society's decree that only thin is beautiful, imbedding into the mindset of the art form notions that now affect how female professional opera singers are depicted and even employed.

As lirico-spinto soprano commonly indicates a soprano with a heavier voice than lyric soprano and a lighter voice than dramatic soprano, there are many problems in the assessment of the voice type. Lirico-spinto soprano is characterized differently by various scholars and sources offer contrasting and insufficient definitions. It is commonly understood as a pushed voice, as many interpret spingere as ‘to push.' This dissertation shows that the meaning of spingere does not mean pushed in this context, but extended, thus making the voice type a hybrid of lyric soprano voice type that has qualities of extended temperament, timbre, color, and volume. This dissertation indicates that the lack of published anthologies on lirico-spinto soprano arias is a significant reason for the insufficient understanding of the lirico-spinto soprano voice. The post-Verdi Italian group of composers, giovane scuola, composed operas that required lirico-spinto soprano voices. These giovane scuola composers include Alfredo Catalani (1854 –1893), Umberto Giordano (1867 –1948), Pietro Mascagni (1863 –1945), Giacomo Puccini (1858 –1924), and Riccardo Zandonai (1883 –1944). Descriptions of the soprano voices that premiered these roles are included in this document to determine the suitability of the lirico-spinto soprano voice for each role.

This project explores the intersection of literature and science from the mid-eighteenth century to the mid-nineteenth century in the context of this shift in conceptions of space and time. Confronted with the rapid and immense expansion of space and time, eighteenth and nineteenth-century philosophers and authors sought to locate humans' relative position in the vast void. Furthermore, their attempts to spatially and temporally map the universe led to changes in perceptions of the relationship between the exterior world and the interior self. In this dissertation I focus on a few important textual monuments that serve as landmarks on this journey. During the eighteenth and nineteenth centuries, the intersection of literary and scientific texts transformed perceptions of space and time. These transformations then led to further advancements in the way scientific knowledge was articulated. Imagination became central to scientific writing at the same time it came to dominate literary writing. My project explores these intersecting influences among literature, astronomy, cosmology, and geology, on the perceptions of expanding space and time.

The purpose of this project is to conduct and analysis of the role and symbolism of the trumpet in two early eighteenth century Spanish music dramas: La Guerra de los Gigantes by Sebastian Duron and Los Desagravios de Troya by Joaquin Martinez de la Roca.
