2	Determinação empírica da evapotranspiração em zona ripária e áreas vizinhas (Cerrado stricto sensu e eucalipto) / Empirical determination of evapotranspiration in the riparian zone and neighboring areas (Cerrado stricto sensu and eucalyptus) Hatum Ponton, Andres Felipe 03 March 2017 (has links) Em zonas ripárias o nível freático encontra-se próximo à superfície do solo e tem contato com as raízes da vegetação. Como resultado, as taxas de evapotranspiração (ET) são elevadas, gerando flutuações diárias do nível de água subterrânea. Apesar da riqueza hídrica que a América Latina possui, estudos sobre a evapotranspiração nas suas zonas ripárias são raros. Os prováveis motivos da pouca investigação na área podem ser atribuídos ao difícil acesso econômico para adquirir equipamentos necessários para a sua medição. Além disso, a aplicação de técnicas como sensoriamento remoto, eddy covariance ou a razão de Bowen é limitada, devido à bordadura das zonas ripárias, que geralmente é estreita. O objetivo deste trabalho foi determinar a ET em zona ripária e áreas vizinhas através de métodos baseados na flutuação diária do nível de água subterrânea. No desenvolvimento deste estudo foram instalados poços de monitoramento na bacia hidrográfica do Ribeirão da Onça. A profundidade do nível freático foi registrada em dataloggers em intervalos de 15 minutos, no período de 09/2015 a 10/2016. O rendimento específico transiente (Sy) foi estimado através da modernização do funil de Haines acoplado a uma balança de precisão.Em função do regime de flutuação diária do nível freático, foi adotado o Sy correspondente a 6 horas de drenagem. Os resultados mostram que na zona ripária a evapotranspiração oscila entre 2,74 e 14,90 mm/d. Para o Cerrado stricto sensu e o eucalipto, a variação da ET é de 1,23 a 2,02 mm/d e 1,96 a 5,45 mm/d, respectivamente, sendo coerentes com resultados prévios obtidos no Brasil. A aplicação de métodos da flutuação diária mostra ser economicamente viável e ter potencial para estimar a evapotranspiração em áreas estreitas. / In riparian zones the groundwater is close to the soil surface and the roots of its vegetation have contact with it. As a result, evapotranspiration (ET) rates are high, generating diurnal groundwater level fluctuations. Despite Latin America\'s water resources wealth, reports of evapotranspiration in its riparian zones are scarce. The probable reasons of little investigation in the area can be attributed to the economical difficulties to access the equipments necessary for this kind of measurement. Furthermore, the application of techniques as remote sensing, eddy covariance or Bowen ratio is limited, due to the usual narrow fetch that are found in the riparian zones. The aim of this study was to determine the ET in the riparian zone and its surroudings areas, using methods based on the diurnal groundwater level fluctuations. To develop this study, monitoring wells were installed in the Ribeirão da Onça basin. The water table depth was recorded in dataloggers using a 15-minute interval, from 09/2015 to 10/2016. The transient specific yield was estimated by improving the Haines funnel coupled to a precision balance. In function of the daily fluctuation regime of the groundwater table, it was adopted the S*y corresponding to 6 hours of drainage. The results show that, in the riparian zone, evapotranspiration ranges from 2,74 to 14,90 mm/d. For Cerrado stricto sensu and eucalyptus, the ET variations are 1,23 to 2,02 mm/d and 1,96 to 5,45 mm/d, respectively, being consistent with previous studies performed in Brazil. The application of diurnal groundwater level fluctuations methods shows to have the potential to estimate evapotranspiration in narrow areas, with low economic investment.

4	John Haines and American Nature Writing: An Environmental Ethic of Quiet Attention Sam T Dobberstein (9182327) 30 July 2020 (has links) The idea of “wilderness,” of nature itself, is being interrogated in history, philosophy, and English departments throughout the academy; books on our place in the natural world have prominent spaces on shelves in bookstores; newspapers feature editorials on climate change and nature preservation. More attention than ever is being paid to environmental philosophers and nature writers as the ongoing climate crisis slowly but steadily worsens. All the while, however, some important thinkers on these subjects of nature and wilderness are utterly forgotten. My thesis focuses on the work of one of these neglected thinkers, the poet and essayist John Haines (1924-2011). Haines’s name is not mentioned often, if ever, in discussions of prominent American nature writers, and I aim to demonstrate why that is an unfortunate exclusion. Guided by his decades as a subsistence hunter and fur-trapper in the Alaskan bush, John Haines offers a perspective on the world outside of us that deserves consideration. I compare and contrast his ideas with those of other nature writers and poets, as well as environmental philosophers and theorists, and argue that he offers a unique and transformative vision of our relationship to the natural world and the non-human animals that live all around us.<br> Literature John Haines Environmental ethics Nature poetry Environmental literature Nature writing
5	Savage in limbo a study in lighting design Haines, Kenneth 01 May 2012 (has links) Designing the elements of a theatrical production is a unique and often experimental process. This process changes from show to show, and it can be difficult for a viewer to differentiate mistakes from design choices without a background in lighting. That is why it is important to take a look at the design process step by step. Two goals I strove for when designing Savage In Limbo were, how the director's concept blended with a design and if the integrity of the designer's vision was evident on stage. To explore these goals, script analysis and consideration of the director's vision are two very important processes. Additionally, an exploration of the design process will better describe the growth and personal achievements of the design. This thesis will show the process of the lighting design for The University of Central Florida's 2011 production of John Patrick Shanley's Savage In Limbo. The project will highlight the design achievements and the goals explained previously, and create a formal dialogue on this specific design in order to provide insight into the process. When analyzing the design it was important that I assessed the process as well as the product by looking at whether the design met the expectations of the script and audience. This thesis will also explore how my past experiences, education and current skill level have prepared me for this design process in order to create a guideline for others interested in the development of knowledge needed for design.

Instituto de Química. Programa de Pós-Graduação em Geociências-Geoquímica. Niterói, RJ / Através do modelo de área limitada Eta, que foi desenvolvido pela Universidade de Belgrado em conjunto com o Instituto de Hidrometeorologia da Iugoslávia, aplicou-se a este modelo o Índice de Haines que é especialmente um índice de estabilidade atmosférica desenvolvido para uso previsão de desenvolvimento de queimadas. Este índice é determinado combinando a estabilidade atmosférica e a umidade do ar de níveis pré-determinados da atmosfera resultando em valores de propagação de fogo. Para estabelecer e discutir sobre as queimadas no Brasil, é necessário saber as condições atmosféricas favoráveis para que ocorra este fenômeno. Assim foram feitas análises dinâmicas e sinóticas de grande escala sobre a América do Sul e do Brasil. Foram observadas imagens de satélite e também foram coletados dados de normais climatológicas para obter-se uma visão geral do escoamento da atmosfera, direção dos ventos, sistemas sinóticos dominantes e os fenômenos atmosféricos que influenciam o tempo, clima e microclima de cada região do Brasil. Para tal, foram gerados mapas do Índice de Haines durante os anos de 2003 e 2004, reanálise e gráficos comparativos matriciais entre os focos de calor com as imagens de satélite NOAA-12, para verificar a validade deste índice para o Brasil. O Índice de Haines é usado em vários países como o Canadá, Estados Unidos, Austrália, países da União Européia e no Sudeste Asiático. O número de focos de incêndios cresce a cada ano, assim este estudo visa estabelecer mais uma ferramenta para as medidas de prevenção e de controle dos focos de calor no Brasil / Through the model of limited area Eta, that was developed by the University of Belgrade together with the Institute of Hidrometeorology of Yugoslavia, was applied to this model the Index of Haines that is especially an index of Atmospheric stability developed for use forecast of development of burning. This index is determined combining the atmospheric stability and of the humidity of the air in the lowest level of the atmosphere resulting in values of fire propagation for other levels of the atmosphere. To establish and to discuss on the burning in Brazil, it was necessary to know the favorable atmospheric conditions so that it happens this phenomenon, they were made like this dynamic analyses and sinotics of great scale on South America and of Brazil, satellite images were observed and also data of climatological normal were collected, to obtain a general vision of the drainage of the atmosphere, direction of the winds, systems dominant sinotics and the atmospheric phenomena that influence the weather, climate and microclimatic of each area of Brazil. Maps of the Index of Haines were generated during the years of 2003 and 2004, reanalisys and graphs comparative matrix among the burning with the satellite images NOAA-12, to verify the validity of this index to Brazil. The Index of Haines is used at several countries as Canada, United States, Australia, countries of the European Union and in the Asian Southeast. The number of focuses of fires grows every year. This study seeks to establish one more tool for the prevention measures and of control of the focuses of heat in Brazil Sensoriamento remoto Meteorologia Queimadas Climatologia Índice de Haines Focos de calor ou queimadas Modelagem numérica Meteorologia Climatologia Modelo Eta Satélites ambientais Sensoriamento remoto Produção intelectual Remote sensing Meteorology Burned
7	The Limits of Fire Support: American Finances and Firepower Restraint during the Vietnam War Hawkins, John Michael 16 December 2013 (has links) Excessive unobserved firepower expenditures by Allied forces during the Vietnam War defied the traditional counterinsurgency principle that population protection should be valued more than destruction of the enemy. Many historians have pointed to this discontinuity in their arguments, but none have examined the available firepower records in detail. This study compiles and analyzes available, artillery-related U.S. and Allied archival records to test historical assertions about the balance between conventional and counterinsurgent military strategy as it changed over time. It finds that, between 1965 and 1970, the commanders of the U.S. Military Assistance Command, Vietnam (MACV), Generals William Westmoreland and Creighton Abrams, shared significant continuity of strategic and tactical thought. Both commanders tolerated U.S. Army, Marine Corps, and Allied unobserved firepower at levels inappropriate for counterinsurgency and both reduced Army harassment and interdiction fire (H&I) as a response to increasing budgetary pressure. Before 1968, the Army expended nearly 40 percent of artillery ammunition as H&I – a form of unobserved fire that sought merely to hinder enemy movement and to lower enemy morale, rather than to inflict any appreciable enemy casualties. To save money, Westmoreland reduced H&I, or “interdiction” after a semantic name change in February 1968, to just over 29 percent of ammunition expended in July 1968, the first full month of Abrams’ command. Abrams likewise pursued dollar savings with his “Five-by-Five Plan” of August 1968 that reduced Army artillery interdiction expenditures to nearly ten percent of ammunition by January 1969. Yet Abrams allowed Army interdiction to stabilize near this level until early 1970, when recurring financial pressure prompted him to virtually eliminate the practice. Meanwhile, Marines fired H&I at historically high rates into the final months of 1970 and Australian “Harassing Fire” surpassed Army and Marine Corps totals during the same period. South Vietnamese artillery also fired high rates of H&I, but Filipino and Thai artillery eschewed H&I in quiet areas of operation and Republic of Korea [ROK] forces abandoned H&I in late 1968 as a direct response to MACV’s budgetary pressure. Financial pressure, rather than strategic change, drove MACV’s unobserved firepower reductions during the Vietnam War. 11th marines 12th marines abrams air force allied american way of war ammunition army artillery attrition arvn australian b-52 birtle budget cap cea classical clausewitz clifford coled-v collins communist congress constraints conventional counter-battery counterinsurgency dollar expenditures filipino finances fire support firepower five-by-five free world military fwmaf h&i haines harold harrassment hunt hybrid interdiction johnson kalergis komer korean krepinevich laird leonard taylor lewy lyndon macv marines mcnamara mekong nagl new zealand nixon nva observed operations philippine preemptive preparatory resor restraint riverine rok savings sensors sorley south vietnamese strategy summers tactics thai third country trinity unconventional unobserved usarv van fleet viet cong vietnam westmoreland wheeler wise men
