A presente pesquisa apresenta uma proposta de treinamento para a improvisação de uma cadenza na peça “The Days Fly By” de Frederick Rzewski. A improvisação é um aspecto que se manifesta de várias maneiras no trabalho e na trajetória deste compositor, sendo ele próprio pianista reconhecido por seus improvisos de cadenzas em concertos tradicionais. Seu processo de composição está intimamente relacionado ao da improvisação. É comum em suas composições a inclusão de uma seção em aberto para ser improvisada pelo intérprete. Utilizo os conceitos de referente, base de conhecimento de Jeff Pressing e ponto de partida de Bruno Nettl associados a um modelo de aprendizagem da improvisação proposto por Barry J. Kenny & Martin Gellrich. Esta pesquisa apresenta proposta de exercícios de improvisação fundamentados nos elementos detectados em uma análise da peça. / This research presents a training proposal for the improvisation of a cadenza in Frederich Rzewski!s"the Days Fly By". Improvisation is an aspect that, in several forms, appears in the work and trajectory of this composer. Himself a pianist, he is well known for his improvisations of cadenzas in traditional concerts. He has been a jazz musician and his process of composition is intimately related to the improvisation. It is usual to find in his compositions the inclusion of an open section to be improvised by the performer. I utilize Jeff Pressing!s concepts of referent, knowledge base and Bruno Netti!s point of departure associated to a training model of improvisation proposed by Barry J. Kenny and Martin Gellich. This research presents a proposal for exercises of improvisation grounded in revealed elements on an analysis of the piece.

A cultura da videira \'Niagara Rosada\' apresenta grande importância em diferentes regiões produtoras, principalmente no estado de São Paulo. Para a produção dessa uva é fundamental a utilização da técnica cultural da poda, que pode ocorrer em diferentes épocas. Dessa forma o presente estudo teve como objetivo comparar o desenvolvimento da videira \'Niagara Rosada\' podada em diferentes épocas mediante a análise de características como o comprimento dos ramos, velocidade média de crescimento de ramos, duração em dias de cada período do ciclo produtivo e soma térmica em graus-dia (GD). As épocas de poda adotadas foram de inverno, com realização em 04/08/2010 e de verão, com realização em 28/01/2011. O delineamento estatístico utilizado foi o de blocos ao acaso com 7 e 8 unidades experimentais cada, totalizando 30 unidades. Cada bloco foi uma planta e a unidade experimental foi um ramo. Para a análise de médias foi empregado o teste de Tukey para comparar os tratamentos de poda de inverno e poda de verão. As variáveis foram comparadas em relação aos períodos do ciclo produtivos: poda à colheita, brotação à colheita, poda à brotação, brotação ao florescimento, florescimento ao início da maturação dos frutos e início da maturação dos frutos à colheita. Houve resultado significativo em todas as comparações entre os tratamentos, de forma que se confirmou que em relação ao tamanho dos ramos, a poda de inverno apresentou ramos mais compridos do que a poda de verão. Em relação à velocidade média de crescimento dos ramos, esta foi superior na poda de inverno do que o observado na poda de verão. Já na duração do ciclo produtivo, houve maior duração no início do ciclo na poda de inverno e maior duração no final do ciclo na poda de verão, de forma que no ciclo como um todo a duração foi praticamente a mesma. Finalmente para a soma térmica, a poda de inverno apresentou valores superiores em todo o ciclo, excetuando-se o período do florescimento ao início da maturação dos frutos, em que a poda de verão apresentou valores superiores. / The importance of the \'Niagara Rosada\" crop is major in several regions, especially in the state of São Paulo. In the production of this vine tree the use of pruning is essential, which can occur in several seasons. With that in mind, this study has as objective to compare \'Niagara Rosada\' vine tree\'s development under different pruning seasons by analyzing characteristics as the length of the branch, average branch growth velocity, duration in days of the production cycle and degreedays (DD). The adopted pruning seasons were the winter pruning, being done in 08/04/2010, and the summer pruning, being done 01/28/2011. As experimental plot were use 4 plants, with 7 or 8 branches each, with the total of 30 branches. To analyze the results was used the Tukey test, comparing the treatments in the different periods of the production cycle (Pruning to Harvest, Sprout to Harvest, Pruning to Sprout, Sprout to Flowering, Flowering to Early Ripening and Early Ripening to Harvest. There was a significant difference between the treatments in all the comparisons. For the length of the branches, the winter pruning showed bigger branches in all the periods than the length of the summer pruning. As for the average branch velocity, it was superior in all the periods in the winter pruning. When considering the duration in days of the periods of the production cycle there was, in the beginning, a longer duration in the winter pruning an a longer duration in the end of the cycle for the summer pruning. When considering the total duration both treatments presented almost the same number. Finally, for the degree-days, the winter pruning showed a bigger rate in all the cycle, except in the Flowering to Early Ripening period, in which the summer pruning showed a bigger rate.

The aim of this thesis was to investigate how fiber growth of goats is determined by genotype, (purebred Angora and crossbred between Angora and Boer goat), physiological stages of the females from mid pregnancy until fifty days after the kids had been weaned and the plane of nutrition. Twelve Angora (pure bred) and ten Angora x Boer goat doe's with an initial mass of 28.70±4.42, between three and five years of age were used. Half of them received 120% NRC energy requirements and the other half received 80% requirements. Mohair patches of 100cm2 were collected from the animals at parturition, mid-lactation, weaning and fifty days post weaning. The fiber greasy weight started declining with commencement of lactation in crossbred animals of both high and low nutrition. The greasy mass again increased from the period of weaning until fifty days post weaning suggesting that crossbred animals do not produce a lot of fiber at the expense of fetal and kid growth. Since fiber production from the crossbred animals is lower, I recommend that the Angora genotype be increased to gain more fiber and further research be done on the topic. / Dissertation (MInstAgrar)--University of Pretoria, 2010. / Animal and Wildlife Sciences / unrestricted

Two thousand and twelve marked the fortieth anniversary of Title IX and the first Summer Olympic Games in which all attending nations sent female competitors. Too often, scholars of sport history conservatively frame the experiences of girls and women within a narrative of progress. College women's sport participation in particular is framed as a linear narrative beginning with the "new woman's" foray in college physical training, the non-competitive interwar coed, and the post Title IX female athlete. It is within this narrative that the college play day, a sport practice emerging in California and Washington in 1926 began to gain momentum as an additional form of extramural competition for college women. In this dissertation I interrogate which historical and societal forces contributed to the invention, diffusion, and evolution of the college play day. Though the play day is briefly included in descriptive narratives about women's physical activity and sport during the interwar era, deeper explorations are absent. This study aims to further elucidate the extent and variety of forms that the play day took. I aim to explore its general value within the college setting and its reception among women physical educators, colleagues, and play day participants. An additional research question I pose is what are the roles and contributions of certain individuals, alliances, and organizations involved in the invention, adoption, and evolutions of the college play day? Last, I question whether or not the play day is a site in which gender relations or other intersecting relations of power were reproduced, constructed, or transformed?

Field and laboratory experiments were conducted to elucidate various factors influencing the temperature-dependent larval eclosion of winter moth, Operophtera brumata L, in New England. We found no difference in duration of the embryonic stage of eggs reared from larvae collected in Massachusetts (MA) and on Vancouver Island, British Columbia (BC), where winter temperatures are rarely below freezing. The number of growing degree days (GDD) required for larval eclosion declined with the number of days chilled in the laboratory and number of days below freezing in the field, confirming the findings of previous studies. Thus, eggs hatched with fewer GDD, when the spring came later than usual. Date of oviposition had no effect on date of hatch. Eggs laid by naturally occurring (feral) females hatched sooner with lower GDD than eggs from laboratory-reared females from MA and BC held on the same trees over the winter. South-facing eggs on the stems of trees hatched on average 1.6 days sooner than north-facing eggs. Growing degree days calculated from bi-hourly measures of temperature were 15% greater than GDD estimates based on the average of daily maximum and minimum temperatures, as used by many GDD estimates made for online sources. Over two years, the mean GDD in ⁰C for hatch of feral eggs based on bihourly temperature measurements, a 1 Jan start date and a 3.9⁰C developmental threshold was 176.53 ± 6.35SE

The Markov chain process for predicting the occurence of a sequence of rainless days, a standard technique, is critically examined in light of the basic underlying assumptions that must be made each time it is used. This is then compared to a simple binomial model wherein an event is defined to be a series of rainless days of desired length. Computer programs to perform the required calculations are then presented and compared as to complexity and operating characteristics. Finally, an example of applying both programs to real data is presented and further comparisons are drawn between the two techniques.

Research was conducted using the Soil-Plant-Atmosphere-Research (SPAR) units at Mississippi State University, Starkville, MS to investigate temperature effects on warm- and cool-season turfgrasses. Data collected include clipping yield, total root biomass, and relative chlorophyll index (RCI). Cultivars and species in the study included: ‘Latitude 36’, ‘Tifway’, ‘MSB-285’, and ‘TifEagle’ bermudagrass, ‘Meyer’ zoysiagrass, ‘Penn A1/A4’ and ‘Penncross’ creeping bentgrass, ‘Midnight’ Kentucky bluegrass, ‘Fiesta 4’ perennial ryegrass, and ‘Falcon V’ tall fescue. Grasses were grown in the SPAR units at varying day/night temperature regimes. Clipping yield was collected every three days, and regression was used to determine the temperature at which clipping yield equaled zero. Root biomass was collected at the conclusion of the trial, while RCI was taken once weekly. Base temperature for warm-season grasses ranged from 12.5 to 13.2°C. Determined optimum temperatures ranged from 31.8 to 36.1°C for warm-season turfgrasses and 18.8 to 20.6°C for cool-season turfgrasses.

An improved knowledge regarding what spatial scale temperature data is needed for ice-prediction would improve calculations how ice-coverage has been affected over time. Which by extension would give insight how ice might response to climate change. The purpose of this study was to find out if ice-growth in Sävar River could be explained by both local and regional temperature data, and what factors beyond temperature affect ice-growth. To accomplish this, I analyzed time-lapse photos from Sävar River during a three-month period. I found out that the use of regional temperature data to explain ice-growth on a local scale is limited due to the differences in accumulated degrees. The local temperature data measurement accumulated -2281 °C from ice began to grow until the whole channel was ice-covered and the regional temperature data accumulated -1901 °C under the same period. My findings support the assumption that frazil ice in large concentrations seem to increase ice-growth. Furthermore, no relation between ice-growth/decrease and precipitation or wet spots was found in this study.

The purpose of this study is to compile the major eschatological prophecies and teachings found in the scriptures and in the discourses and writings of Latter-day Saint General Authorities; to include sufficient explanatory material to interrelate and clarify the events which are expected to transpire; and to establish, in so far as is possible, the order of these eschatological events.

Since 1978 casino and gaming facilities in the United States have grown substantially. Drawing outside customers has helped to improve the local communities surrounding the gaming facilities. In a similar fashion, United States horse racing aims at increasing traffic and wagering at race tracks throughout the United States (but unlike casinos little expansion). Along with the fiscal impact to the United States, the horse racing industry has created thousands of jobs, and the industry is experiencing continual growth in nominal gross wagering. Many state’s have breeder programs that enhance purses and horses bred and raced in- state. The goal of this research was to assess whether these state bred event days (SBED) attendance and/or wagering were comparable to controls, the proximal weeks. Data was collected over a three year period and included sixteen states with such programs. The data was analyzed using ordinary least squares regression methods. Two models were run, an on-track wagering model, and an attendance model on a set of structural variables. In the on-track wagering model positive variables, including purse levels, change in track venue, and SBED concurrent with a major national race day (Triple Crown or Breeders’ Cup days), were associated with an increase in on-track wagering. California and New York SBED experienced significant increases in on- track wagering over open race days. The attendance model had similar results. While SBED programs are not used in every state, their overall contribution to horse racing is apparent and substantial. The enhancement and introduction of new well planned SBED programs in United States racing jurisdictions might increase attendance and wagering.
