Measuring Atmospheric Ozone and Nitrogen Dioxide Concentration by Differential Optical Absorption Spectroscopy (open access)

Measuring Atmospheric Ozone and Nitrogen Dioxide Concentration by Differential Optical Absorption Spectroscopy

The main objective was to develop a procedure based on differential optical absorption spectroscopy (DOAS) to measure atmospheric total column of ozone, using the automated instrument developed at the University of North Texas (UNT) by Nebgen in 2006. This project also explored the ability of this instrument to provide measurements of atmospheric total column nitrogen dioxide. The instrument is located on top of UNT’s Environmental Education, Science and Technology Building. It employs a low cost spectrometer coupled with fiber optics, which are aimed at the sun to collect solar radiation. Measurements taken throughout the day with this instrument exhibited a large variability. The DOAS procedure derives total column ozone from the analysis of daily DOAS Langley plots. This plot relates the measured differential column to the airmass factor. The use of such plots is conditioned by the time the concentration of ozone remains constant. Observations of ozone are typically conducted throughout the day. Observations of total column ozone were conducted for 5 months. Values were derived from both DOAS and Nebgen’s procedure and compared to satellite data. Although differences observed from both procedures to satellite data were similar, the variability found in measurements was reduced from 70 Dobson units, with …

The European View of the Incas in the Sixteenth Century (open access)

The European View of the Incas in the Sixteenth Century

This study seeks to ascertain European views concerning the nature of the indigenous population of Peru by employing contemporary works of Spanish chroniclers. Major focus is on the ideological background of the conquest with elaborations on Iberian philosophies held by conquistadors. Equally important are evaluations of Indian religion and social customs based on such sources as Aristotelian and Thomist doctrines as understood by Spanish writers. Political organization and the hierarchy of rulers play vital roles in determining why the Spaniards overwhelmed the Indians. Conquest destroyed the socio-economic structure of the Inca Empire, and the bonds holding communities together were lost as the Incas accepted Catholicism as their cult.

The Controversial Identity of Flamenco Jazz: A New Historical and Analytical Approach (open access)

The Controversial Identity of Flamenco Jazz: A New Historical and Analytical Approach

There are certain recordings by important artists such as Lionel Hampton, Miles Davis, John Coltrane, Pedro Iturralde, Chick Corea, and Paco de Lucía, among others, that have been associated with the label flamenco jazz. This label is entering jazz discourse, and it needs to be better understood in order to clarify its history, its identity, and its impact on recent developments in flamenco that are labeled nuevo flamenco. There is a lack of agreement in the existent literature on flamenco jazz on the evaluation of these recordings and these artists' achievements and contributions to this field. These writings encompass authors from different backgrounds: journalists, critics, and musicologists, who have approached their analysis of the recordings from different perspectives. The differences in professional backgrounds, approaches, and purpose of the writings of these authors has resulted in controversy about this label. Therefore, the flamenco jazz scholarly conversation needs more objective writings from an analytical point of view. This historiographical study presents a more comprehensive evaluation of flamenco jazz by discussing selected recordings using analytical tools from jazz studies. These analytical arguments clarify the aesthetics of flamenco jazz and the artistic processes that these artists went through when combining musical elements from flamenco …

The Influence of Flamenco on Selected Works of Picasso (open access)

The Influence of Flamenco on Selected Works of Picasso

This thesis investigates, analyzes, and discusses Picasso's imagery in the cultural context of the nineteenth-century Spanish tradition of flamenco. Two published photographs featuring the elderly artist with the gypsy guitarist Manitas de Plata initiated the study, and led me to the conclusion that selected works by Picasso were influenced psychologically, thematically, and formally by his youth which was spent in the Andalusian province of Malaga and later in Barcelona. Picasso's early artistic education occurred at precisely the same time and place as The Golden Age of Flamenco in Spain, a cultural phenomenon that profoundly affected both his life and art.

An Investigation of the Traditional  Cante Jondo as the Inspiration for the Song Cycle  Five Poems of Garcia Lorca by Elisenda Fabregas (open access)

An Investigation of the Traditional Cante Jondo as the Inspiration for the Song Cycle Five Poems of Garcia Lorca by Elisenda Fabregas

The traditional cante jondo is a song unique to Andalusia as it developed from the "mosaic" of cultures that have inhabited its borders, including Arabs, Jews and Gypsies. The genre expresses the history of the region, reveals the typography of the landscape and cries the tears of its people. "Deep song," the translation for cante jondo, is the forerunner of the flamenco, but it is a communication of a dark soul rather than an exuberant entertainment. The original folk idiom is a medium less concerned with beauty than the cathartic release of pain of every day life. It expresses the soul of Andalusia. This study explores the history and the poetic and musical forms Andalusian cante jondo as the inspiration for the poetry of Federico Garcia Lorca set by Elisenda Fabregas in the song cycle, Five Poems of Garcia Lorca (1992). Lorca felt the validity of "deep song" and he was disturbed that it was being corrupted by commercialism and was afraid it would be lost to posterity. His goal was to preserve the essence of the song and lift it to an artistic plain. He saw folk music as the core of the national musical and literary identity in …
