Waterfowl foods and use in managed grain sorghum and other habitats in the Mississippi Alluvial ValleyWiseman, Alicia Joy 11 December 2009 (has links)
Grain sorghum provides energy-rich seeds for waterfowl. I conducted experiments in 22 sorghum fields in Arkansas, Mississippi, and Louisiana during falls 2006 – 2007 to evaluate abundance of ratoon grain (i.e., second crop after harvest), waste grain, and natural seeds. I also conducted surveys of wintering waterfowl in flooded croplands and moist-soil wetlands to evaluate if ducks and geese differentially used habitats. Fertilized plots in 2007 produced >4 times more ratoon grain (x = 219.57 ± 39.65 [SE] kg/ha) than other treatments. Fertilized plots in southern regions of my study area produced ~5 times more ratoon grain (x = 262.93 ± 50.28 kg/ha) than others. Mallards and other ducks used moist-soil wetlands (x >65 ducks/ha) more than other habitats. I did not observe geese using flooded sorghum. I recommend not manipulating sorghum stubble after harvest, fertilizing, and flooding it after ratoon grain has matured, and integrating moist-soil wetlands into agricultural lands.

Uma jornada em quadrinhos : comparação entre as adaptações chinesa e italiana de Jornada ao Oeste /Antônio, Guilherme Henrique Gooda January 2019 (has links)
Orientador: Marcelo Magalhães Bulhões / Resumo: As transformações sociais e políticas do final do século XX trouxeram profundas considerações e discussões que foram incorporadas às produções midiáticas da época. Dentre essas mídias os quadrinhos já se destacavam como ferramenta política tanto na China como na Itália, e essas produções eram aprimoradas conforme a tecnologia se desenvolvia. Esta dissertação busca perceber, através de uma análise comparativa, como cosmovisão atua no processo de adaptação midiática. Tomando por obra base a narrativa Jornada ao Oeste do século XVI, italianos e chineses criaram obras distintas sobre todos os aspectos: O Jornada ao Oeste em Quadrinhos adaptação chinesa de 1962 e a produção italiana Lo Scimmiotto de 1976. As duas narrativas contam como a simbologia nos quadrinhos foi moldada por artistas que interpretam e ressignificam um acervo simbólico e cultural formando uma obra coesa e repleta de significações. Ao traçar os elementos comparativos entre as duas obras e apresentá-los quadro a quadro, argumentamos que embora o enredo da narrativa base se sustente, existe um hipertexto que só pode ser acessado ao conhecer o acervo histórico, social e cultural. Esse hipertexto se relaciona diretamente com a cosmovisão e com permanência das imagens como tratados nos estudos sobre arte de Warburg e Panofsky. Por fim este trabalho discute como os quadrinhos enquanto mídia se presta a receber este tipo de manifestação artística como nenhum outro meio de comunicação devido a sua linguagem própria. / Abstract: The end of the 20th century brought deep political and social discussions that were embodied by the media productions. Among those medium, comics started to point out as a political tool both in Italy and China, those production evolved together with the technology. The present work aims to point, through a comparative analysis, how the worldview acts in the adaptation process. Taking the 16th century literary work Journey to the West, Chinese and Italians created distinct adaptations among all aspects: Journey to West in Comics, the chinese adaptation from 1962 and the italian production Lo Scimmiotto from 1976. Both comics have shown us how the symbolic system in comic books were molded by artists, who interpreted and resignified a cultural collection of symbols creating a coherent work. By tracing those comparative elements and present them each comic strip at a time, we argue that although the original plot remains, there is an hypertext that can only be accessed by knowing the social, cultural and historical context. The hypertext is directly linked to the cosmovision and to the remnants of images as discussed previously by Warburg and Panofsky. Lastly the work discuss how comic books as a media offer itself to this kind of artistic expression as any due to his unique language. / Mestre

The Old Alcalde: Oran Milo Roberts, Texas's Forgotten Fire-EaterYancey, William C. 05 1900 (has links)
Oran Milo Roberts was at the center of every important event in Texas between 1857 and 1883. He served on the state supreme court on three separate occasions, twice as chief justice. As president of the 1861 Secession Convention he was instrumental in leading Texas out of the Union. He then raised and commanded an infantry regiment in the Confederate Army. After the Civil War, Roberts was a delegate to the 1866 Constitutional Convention and was elected by the state legislature to the United States Senate, though Republicans in Congress refused to seat him. He served two terms as governor from 1879 to 1883. Despite being a major figure in Texas history, there are no published biographies of Roberts. This dissertation seeks to examine Roberts's place in Texas history and analyze the factors that drove him to seek power. It will also explore the major events in which he participated and determine his historical legacy to the state.

Hydrologie et géochimie des transports fluviaux dissous et particulaires dans le bassin versant du Milo (République de Guinée)Sow, Mamadou Alpha 14 May 2018 (has links) (PDF)
En Guinée, la disponibilité des ressources en eau est soumise à de graves problèmes de gestion avec des conséquences importantes pour les populations, notamment à Kankan où la plupart des puits tarissent pendant la saison sèche, et où la fourniture régulière de l’eau à partir de la rivière Milo n'est pas assurée dans tous les quartiers de la ville. Le Milo et son bassin versant représente donc un enjeu important pour les habitants de cette ville. Le Milo (480 km de long) qui draine un bassin versant 13 810 km2 est le plus important des affluents rive droite du Niger. Pour évaluer l’impact du bassin versant du Milo et de la ville de Kankan sur la qualité des eaux et des sédiments de ce cours d’eau, 30 échantillons de sédiments de fond ont été prélevés au cours d’une première campagne (juin-juillet 2013) sur l’ensemble des cours d’eau du bassin versant, tandis que durant une deuxième campagne (avril 2014-mai 2015), un suivi régulier a été mis en place sur le Milo en amont et en aval de Kankan. Au cours de cette dernière, 232 échantillons d’eau du Milo (dont 116 utilisés pour l’isotopie), et 26 échantillons de sédiments de fond ont été prélevés sur les stations de Bordo (amont de Kankan) et de Karifamoriah (aval de Kankan). Les concentrations en éléments majeurs et traces, terres rares, COP, COD, pH, alcalinité, l’azote organique, les isotopes de l’oxygène et de l’hydrogène, ainsi que la micro-granulométrie des sédiments ont été mesurés. Les résultats obtenus durant le cycle hydrologique 2014-2015 ont permis d’estimer le flux de matières exportées en solution par le Milo à Kankan à 47 863 t.an-1 et le flux de matières particulaires à 76 759 t.an-1. 92% de ce tonnage est exporté durant la période des hautes eaux. Ces flux permettent d’estimer des vitesses moyennes d’érosion physique (8 t.km-2.an-1) et d’altération chimique (5 t.km-2.an-1) du bassin relativement faibles. Le flux spécifique de CO2 consommé par l’altération chimique est lui aussi relativement faible (76.103 mole.km-2.an-1), mais il reste dans la moyenne des flux de CO2 mesurés sur les bassins couverts de sols latéritiques. Le degré de contamination des sédiments et sa variation spatio-temporelle ont été évalués grâce au calcul du facteur d’enrichissement (FE), en normalisant les concentrations en éléments traces par rapport à Al, Sc et Ti et en prenant le PAAS et l’UCC comme matériaux de référence. La quasi-totalité des éléments traces proviennent essentiellement des processus d’altération et sont d’origine naturelle. Toutefois, un enrichissement modéré à significatif (5 < FE < 20) a été mis en évidence pour Zr et Hf (enrichissements naturels) et As et Sb (impacts anthropiques). Finalement, l’apport anthropique en éléments traces, quand il existe, reste modéré. Les profils de concentrations en terres rares ont permis de montrer que la signature géochimique des sédiments de fond du Milo est homogène sur l’ensemble du bassin et caractéristique des sols latéritiques, non perturbée par la ville de Kankan et elle est proche des signatures du PAAS et de l’UCC. Pour l’ensemble des éléments traces et des terres rares la contribution anthropique reste faible et les fractions disponibles (phases labiles) sur les sédiments (extraction à l’EDTA) sont également faibles, confirmant ainsi que l’essentiel de ces éléments rentrent principalement dans la composition des phases résiduelles.

Hydrologie et géochimie des transports fluviaux dissous et particulaires dans le bassin versant du Milo (République de Guinée) / Hydrology and geochemistry of dissolved and particulate fluvial transport in the Milo watershed (Republic of Guinea)Sow, Mamadou Alpha 14 May 2018 (has links)

Then the Milo river and its watershed represent an important issue for the inhabitants of Kankan. The Milo river (480 km in length) which drains an area of 13 810 km2 is the most important right-bank tributary of the Niger river. To evaluate the impact of the Milo watershed and of the Kankan city on the water and sediments of this river, 30 samples of bottom sediments have been collected during a first campaign (June-July 2013) on the main course from upstream to downstream and on the main tributaries, whereas during a second campaign (April 2014-May 2015) a regular monitoring was set up on the Milo river, upstream and downstream Kankan city. During this campaign, 232 river water samples (of which 116 for isotopic analyses) and 26 bottom sediment samples have been collected at Bordo (upstream) and Karifamoriah (downstream) stations. The concentrations of major and trace elements, rare earth elements, POC and PON, DOC, pH, alkalinity, the isotopic composition of O, H and the micro-granulometry of sediments have been measured. The results obtained during the hydrological cycle 2014-2015 allowed to estimate the fluxes of dissolved (47 863 t.y-1) and particulate (76 759 t.y-1) matters exported by the Milo river at Kankan. 92% of these fluxes are exported during the high flow period. These fluxes allowed us to estimate very low average rates of physical erosion (8 t.km-2.y-1) and chemical weathering (5 t.km-2.y-1) of the Milo catchment. The specific flux of CO2 consumed by chemical weathering (76.103 mole.km-2.y-1) is relatively low but within the range of CO2 fluxes measured in catchments draining lateritic soils. The degree of sediment contamination and its spatio-temporal variation have been assessed using the enrichment factor (EF), by normalizing the trace element concentrations with Al, Sc and Ti and by taking PAAS and UCC as the reference materials. Almost all the trace elements mainly originate from weathering processes and are of natural origin. Nevertheless, moderate to significant enrichments (5 < EF < 20) have been calculated for Zr and Hf (natural enrichments) and As and Sb (anthropogenic impacts). Finally, the anthropogenic contribution of trace elements, when it exists, remains moderate. The rare earth concentration patterns allowed to show the geochemical signature of river bottom sediments is homogeneous within the Milo catchment and characteristic of lateritic soils, non- perturbed by the city of Kankan and close to the PAAS and UCC patterns. For most of the trace and rare earth elements, the anthropogenic contribution remains low and the available fractions (labile phases) in the sediment (EDTA extraction) are also low, confirming that the main part of these elements are mainly in the residual phases.

The classical in the contemporary : contemporary art in Britain and its relationships with Greco-Roman antiquityCahill, James Matthew January 2018 (has links)
From the viewpoint of classical reception studies, I am asking what contemporary British art (by, for example, Sarah Lucas, Damien Hirst, and Mark Wallinger) has to do with the classical tradition – both the art and literature of Greco-Roman antiquity. I have conducted face-to-face interviews with some of the leading artists working in Britain today, including Lucas, Hirst, Wallinger, Marc Quinn, and Gilbert & George. In addition to contemporary art, the thesis focuses on Greco-Roman art and on myths and modes of looking that have come to shape the western art historical tradition – seeking to offer a different perspective on them from that of the Renaissance and neoclassicism. The thesis concentrates on the generation of artists known as the YBAs, or Young British Artists, who came to prominence in the 1990s. These artists are not renowned for their deference to the classical tradition, and are widely regarded as having turned their backs on classical art and its legacies. The introduction asks whether their work, which has received little scholarly attention, might be productively reassessed from the perspective of classical reception studies. It argues that while their work no longer subscribes to a traditional understanding of classical ‘influence’, it continues to depend – for its power and provocativeness – on classical concepts of figuration, realism, and the basic nature of art. Without claiming that the work of the YBAs is classical or classicizing, the thesis sets out to challenge the assumption that their work has nothing to do with ancient art, or that it fails to conform to ancient understandings of what art is. In order to do this, the thesis analyses contemporary works of art through three classical ‘lenses’. Each lens allows contemporary art to be examined in the context of a longer history. The first lens is the concept of realism, as seen in artistic and literary explorations of the relationship between art and life. This chapter uses the myth of Pygmalion’s statue as a way of thinking about contemporary art’s continued engagement with ideas of mimesis and the ‘real’ which were theorised and debated in antiquity. The second lens is corporeal fragmentation, as evidenced by the broken condition of ancient statues, the popular theme of dismemberment in western art, and the fragmentary body in contemporary art. The final chapter focuses on the figurative plaster cast, arguing that contemporary art continues to invoke and reinvent the long tradition of plaster reproductions of ancient statues and bodies. Through each of these ‘lenses’, I argue that contemporary art remains linked, both in form and meaning, to the classical past – often in ways which go beyond the stated intentions of an artist. Contemporary art continues to be informed by ideas and processes that were theorised and practised in the classical world; indeed, it is these ideas and processes that make it deserving of the art label.
