No. of bitstreams: 1 LIGIA SAMPAIO REIS - TESE PPGEA 2006..pdf: 39057759 bytes, checksum: b8a95f345aae5194c46d6f9979e44ece (MD5) Previous issue date: 2006-12 / CNPq / O conhecimento sobre o crescimento das espécies cultivadas permite planejar e manejar de forma racional os cultivos, contribuindo para que as espécies consigam expressar todo seu potencial, além de fornecer dados para a construção de modelos matemáticos capazes de descrever a necessidade de água das culturas, através do conhecimento da evapotranspiração. O objetivo principal deste trabalho foi a caracterização energética e hídrica no desenvolvimento do tomate caqui em ambiente protegido, visando determinação da necessidade de água. Foram feitas as seguintes determinações: fluxos de calor sensível e latente pelos métodos do balanço de energia de Bowen e pelo método de Penman- Monteith; coeficiente da cultura através dos métodos de Linacre, Penman-Monteith e radiação; e evapotranspiração pelos métodos do balanço hídrico e Penman-Monteith. Durante o período experimental, foram tomadas medidas semanais de altura das plantas e comprimento e largura das folhas. Foram ajustados modelos para determinação do índice de área foliar, em função da largura e comprimento das folhas. Comparado ao modelo de Penman-Monteith, o modelo de Linacre subestimou os valores de ETo, quando o saldo de radiação (Rn) foi superior a 7,0 MJ m ; por outro lado, quando Rn ocorreu na faixa de 4 MJ m2 o método de Linacre superestimou a ETo. O saldo de radiação foi consumido em 71% para o fluxo de calor latente no interior do ambiente protegido, e em 15% para o fluxo de calor sensível. Apesar do comportamento dos dois métodos serem os mesmos, os valores encontrados pelo método do balanço hídrico foram maiores que os encontrados pelo método de Penman-Monteith. A relação Rgi e Rge permaneceu constante durante o ciclo com transmissividade de 89%, mostrando, portanto, redução de 18%, provocada pela cobertura de polietileno. A Rg apesar de mostrar uma concordância elevada, apresentou um maior erro quando comparada aos outros elementos, mostrando que existem diferenças significativas entre as mediadas obtidas dentro da estufa e as estimadas pelos dados externos. O valor médio de frutos por planta foi de 21,5, com uma produção de 3,04 kg planta e uma produtividade de 7,6 kg m" , totalizando uma produtividade de 76 t ha" , valor este maior que a média Nacional. Verificou-se, que o maior consumo de água ocorreu na fase reprodutiva. / The knowledge on growth of cultivated species allows to planning and to manage, in a rational way, the cultivations, contributing so that the species get to express ali its potential, besides supplying data for construction of mathematical models capable to describe the need of water by crops, through the knowledge of evapotranspiration. The main objective of this work was the energy and hydric characterization in the development of tomato kaki in greenhouse, seeking determination of the need of water. The following determinations were performed: sensitive and latent heat flows by the methods of energy balance of Bowen and by the method of Penman-Monteith; crop coefficient through the methods of Linacre, Penman-Monteith and radiation; and evapotranspiration by the methods of water balance and Penman-Monteith. During the experimental period, weekly measures of plants height and length and width of leaves were taken. Models were adjusted for determination of the foliar area index, in function of the width and length of the leaves. Compared to the model of Penman-Monteith, the model of Linacre underestimated the values of ETo, when the radiation balance (Rn) was superior to 7.0 MJ m" ; on the other hand, when Rn happened in the strip of 4 MJ m"2 the method of Linacre overestimated ETo. The radiation balance was consumed in 71% by the latent heat flow inside of the greenhouse, and in 15% by the sensitive heat flow. In spite of the behavior of the two methods be the same, the values found by the water balance method were larger than the ones found by the method of Penman- Monteith. The relationship Rgi and Rge stayed constant during the cycle with transmissivity of 89%, showing, therefore, reduction of 18%, provoked by the covering of polyethylene. The Rg, in spite of showing a high agreement, presented a larger error when compared to the other elements, showing that significant differences exist among the measures obtained inside of the greenhouse and the ones estimated by the externai data. The mean value of fruits per plant was of 21.5, with a production of 3.04 kg plant"1 and a productivity of 7.6 kg m"2, totaling a productivity of 76 t ha"1, which is a value larger than the National mean. It was verified that the largest water consumption happened in the reproductive phase.

The purpose of this dissertation is to offer a greater understanding of the potential of genograms through my clinical work from a Bowen Family Systems lens. I account for how I processed and effectively blended metaphorical components, by examining six cases from my two-year journal entries, of bringing genograms to life in sessions. I also explain how I created a useful tool, the Metaphoric Generative Genogram, that can benefit other clinicians working with children and families in the foster care community.

The primary reinforcement used for construction of structural concrete members has a yield strength of 60 ksi. This reinforcement grade was incorporated into construction over 50 years ago and remains the standard. Recent advances in material technology have led to the development of commercially available reinforcing steel with yield strengths of 100 ksi. While greater yield strengths can be utilized in design, it is essential that the bars can be properly anchored and spliced to fully develop their strength. Although design expressions are available for this purpose, they were established considering 60 ksi reinforcement. Therefore, the objective of this research program is to evaluate the development of high-strength reinforcing steel and establish a design expression for the development and splicing of this steel. Two phases of experimental tests were conducted. Phase I was performed by Glucksman (2018) and investigated the influence of splice length and transverse reinforcement on bond strength over four series of beam tests. This study (Phase II) was conducted following Phase I and consisted of reinforced concrete slab and beam testing over three series. An investigation was conducted on reinforcement development with a focus on the effect of splice length, concrete compressive strength, stress-strain relationships of the steel (ASTM A615 vs. ASTM A1035), and transverse reinforcement. Based on the results, the influences of test variables were identified, and a new confinement model was developed that estimates the transverse reinforcement contribution to bond strength. Finally, a design expression is provided for calculating the development and splice lengths of high-strength reinforcement.

From the first electric lights in London along Pall Mall, and in the Holborn Viaduct in 1878 to the nationalisation of National Grid in 1947, the narrative of the simple ascendency of a new technology over its outdated predecessor is essential to the way we have imagined electric light in London at the end of the nineteenth century. However, as this thesis will demonstrate, the interplay between gas and electric light - two co-existing and competing illuminary technologies - created a particular and peculiar landscape of light, a 'lightscape', setting London apart from its contemporaries throughout the late nineteenth and early twentieth centuries. Indeed, this narrative forms the basis of many assertions made in critical discussions of artificial illumination and technology in the late-twentieth century; however, this was not how electric light was understood at the time nor does it capture how electric light both captivated and eluded the imagination of contemporary Londoners. The influence of the electric light in the representations of London is certainly a literary question, as many of those writing during this period of electrification are particularly attentive to the city's rich and diverse lightscape. Though this has yet to be made explicit in existing scholarship, electric lights are the nexus of several important and ongoing discourses in the study of Victorian, Post-Victorian, Modernist, and twentieth-century literature. This thesis will address how the literary influence of the electric light and its relationship with its illuminary predecessors transcends the widespread electrification of London to engage with an imaginary London, providing not only a connection with our past experiences and conceptions of the city, modernity, and technology but also an understanding of what Frank Mort describes as the 'long cultural reach of the nineteenth century into the post-war period'.
