A segurança alimentar é uma necessidade prioritária de produtores primários, processadores e distribuidores de alimentos, além dos próprios consumidores e organismos governamentais. Estas questões se tornam ainda mais importantes considerando que o segmento é composto de pequenos e médios produtores rurais e pequenas empresas que necessitam eliminar os fatores de insegurança jurídica no campo, melhorar a infraestrutura logística e reduzir custos, dentre outros fatores. Este trabalho teve por objetivo geral estudar a relação entre os agentes da cadeia da ovinocultura de corte. Para tanto, primeiramente foi realizada uma pesquisa bibliográfica baseada na teoria da segurança alimentar, produção de ovinos de corte, cooperativismo, gestão da qualidade, custos de transação, de gestão da cadeia de suprimentos, com o propósito de reunir elementos para guiar o estudo de caso único. A pesquisa de campo teve como objeto de estudo uma cooperativa na cidade de Guarapuava, Paraná, e reuniu ao todo unidades de análises compostas por: produtores rurais, gestores da cooperativa, processador e distribuidores (mercados varejista e institucional). Foram realizadas entrevistas com os agentes para identificação da gestão pelos atributos da qualidade exigidos pelos clientes em diferentes formatos: por meio dos seus desdobramentos ao longo da cadeia; das estruturas de governança; da relação e confiança entre os agentes como componentes de avaliação e de desempenho, incertezas e especificidade dos ativos para melhoria contínua dos processos. Esta estrutura resultou em um nível de gestão simples, com visão sistêmica e cooperação mútua entre os agentes desta cadeia, onde a cooperativa lidera e coordena estas ações. A principal relação entre os agentes da cooperativa é a confiança. Os resultados podem ser utilizados como referência para o planejamento da implantação da gestão da qualidade da produção animal e distribuição entre os agentes da cooperativa, assim como para estruturar e guiar auditorias internas e em fornecedores para as processadoras da carne de cordeiro e as empresas do mercado varejista/institucional, respectivamente. / The chain of sheep meat industry requires structuring to supply the demands of the domestic and foreign markets. Food safety is a priority need for primary producers, processors and distributors of food, in addition to consumers themselves and government agencies. These issues become even more important considering that this production chain is made up of small and medium farmers and small businesses that need to eliminate the legal uncertainty factors in the field, improve logistics infrastructure, reduce costs, among other factors. This work aims to study the relationship between the agentes on the sheep meat chain. Therefore, a literature search based on the theory of food security, production of sheep meat, cooperative, quality management, transaction costs, supply chain management, in order to gather information to guide the case study one of a kind. The field research was to study the object of a cooperative and gathered the whole, composite analysis units by: farmers, the cooperative managers, processors, distributors (retail and institutional markets). Interviews were conducted with agents for quality attributes for identity management required by customers in different formats: through its development along the chain; the relationship and trust between the agents as components of evaluation and performance, uncertainty and assets specificity for continuous process improvement. This structure resulted in a level of simple management, systemic vision and mutual cooperation between actors of the chain, where the cooperative leads and coordinates these actions. The main relationship between cooperative agents is trust. The results can be used as a reference for planning the deployment of animal production quality management and distribution between cooperative agents, as well as to structure and guide internal audits and suppliers to the processing of lamb and for companies retail / institutional market, respectively.

Nesta tese, é apresentada uma revisão bibliográfica de reuso potável indireto e reuso industrial. Examina-se na prática dois estudos de caso, um de reuso industrial e um de reuso potável com aplicação para a Baixada Santista. O de reuso industrial refere-se ao projeto de fornecidmento de água oriunda da represa Billings, que com pequeno tratamento é oferecida às indústrias de Cubatão para fins não nobres como por exemplo, refrigeração, aquecimento a vapor, rega de jardins, abatimento de material particulado. etc. Quanto ao de reuso potável a apresentação se faz através de experimentos de laboratórios, examinando-se trihalometanos (THM) e o poder desinfetante de alguns produtos químicos após passagem da água por carvão ativado granular e outros tratamentos, e suas consequências na rede de abastecimento de água. Concluiu-se que o melhor ponto de instalação da captação para o abastecimento de água industrial fica entre os canais de fuga da usina Henry Borden, em Cubatão, por seu melhor desempenho econômico e pela possibilidade de atendimento no futuro a outras indústrias. Ainda, se comprovou a eficiência do carvão ativado granular na remoção dos precursores de THM e o baixo poder desinfetante da cloramina. / There is in this thesis, a small literature revision about the matter, mainly about indirect potable reuse and industrial reuse. In the practical part they are examined in two cases, industrial reuse and potable reuse, both for the Santos Basin. In the Industrial Reuse, there is a project to distribute industrial water to Cubatão industries, using water from Billings after a small treatment. This water is to be used in refrigeration of steel or to boil water to obtain steam or put in solid material to avoid air pollution, etc. In Potable Reuse, there are many laboratory experiences about THM and desinfection by many chemical products and their consequences in distribuition of water. In conclusion, the best place for ínstalation of the collection of water is located between the Henry Borden Power Plant Channels, in Cubatão, for it\'s superior economic performance and for the possibility to support other industries in the future. It has already confirmed the efficiency of the granular activated carbon to remove THM precursors and its inability to desinfect ammonia chlorine.

O objetivo deste estudo foi verificar se existe associação entre a qualidade da água para abastecimento público proveniente do Sistema Guarapiranga e o clima da Região Metropolitana de São Paulo (RMSP). Realizou-se a análise dos dados meteorológicos adquiridos junto à Estação Meteorológica do Instituto de Astronomia, Geofísica e Ciências Atmosféricas da Universidade de São Paulo (IAG/USP) e dos resultados de análises laboratoriais da água do Reservatório Guarapiranga adquiridos junto à Companhia de Saneamento Básico do Estado de São Paulo (SABESP). A partir da relação entre as variáveis observadas em gráficos e testes de associação/correlação, verificou-se a associação/correlação entre a densidade de cianobactérias e as variáveis meteorológicas na RMSP, tais como temperatura atmosférica (T°C), insolação (horas de brilho do sol) e precipitação (mm). Para analisar as interações e relações de cada uma das variáveis meteorológicas em relação à densidade de cianobactérias, foram feitos diferentes recortes de tempo. Todos os dados foram organizados em Planilhas Microsoft® Excel 15.0 (Office 2013) e analisados em gráficos e testes estatísticos. Segundo os resultados deste estudo, a densidade de cianobactérias apresenta associação positiva com os períodos de chuva e temperaturas elevadas (outubro a março) e, juntamente com as análises de dados climáticos dos últimos 42 anos, verificou-se que as condições climáticas ideais para a proliferação de cianobactérias no Reservatório Guarapiranga vêm se acentuando ao longo das últimas quatro décadas, particularmente nos últimos 20 anos. Conclui-se que há indicações de que a densidade de cianobactérias no Reservatório do Sistema Guarapiranga tenha relação temperaturas mais elevadas e pluviosidade e que a proliferação de cianobactérias pode aumentar caso se mantenha a tendência do clima. / This study has aimed to verify if there is a relation between the quality of the water in the Guarapiranga System (reservoir), as it is supplied to the inhabitants, and the climate in the São Paulo Metropolitan Area (RMSP). We have analyzed the data obtained from the Weather station of the Astronomy, Geophysics and Atmospherical Sciences Institute at the University of São Paulo (IAG/USP), as well as the results of the reservoir water laboratory analysis, provided by the basic sanitation company in the State of São Paulo (SABESP). Cyanobacteria density and meteorological variables in the RMSP, such as atmospheric temperature (ToC), insolation (daily solar irradiance) and precipitation (mm), were verified through association/correlation tests and graphics. To analyze the interaction and relation between cyanobacteria density and meteorological variables, were have resorted to different time spans. Data was organized in Microsoft® Excel 15.0 (Office 2013) tables and graphics, and statistically analyzed. According to this study results, cyanobacteria density might be positively associated to periods of rainfall and high temperatures (October to March). Also, along with data analysis of climate throughout the last 42 years, we have observed that the ideal climate conditions for cyanobacteria proliferation in the Guarapiranga reservoir have been stressed in the last four decades, especially during the last 20 years. Therefore, frequency and intensity of cyanobacteria proliferation in the Guarapiranga reservoir may increase according to climate trend in the RMSP.

The Water Supply of Byzantine Constantinople is one of the most outstanding achievements of hydraulic engineering from the Roman world. Working entirely as a gravity-fed system, this infrastructure relied on hundreds of kilometres of masonry channels, winding along the hills of Turkish Thrace and carrying water to Constantinople across different watersheds. The Water Supply was built in two main phases: the first in the mid-fourth century, following the foundation of Constantinople in 330 AD; and the second in the early fifth century. It is not clear whether the aqueducts from these two phases worked independently or as a single system, yet the scale of this would have been colossal, reaching lengths of 450 km between the two aqueducts. However, a full and close understanding of its hydraulic design and function has until now been missing. As such, this investigation aims to: (1) establish a clear route for the aqueducts, both in terms of length and gradient (mapping); (2) determine likely volumes of water entering the system at the various intakes (hydrology); and (3) evaluate its hydraulic behaviour and flow characteristics (hydraulics). While previous work on similar Roman aqueducts yielded only estimates of maximum capacity, this work delves into the engineering of the ancient infrastructure to provide a more realistic assessment of theWater Supply discharge to the City. The physical configuration of the aqueducts is reinterpreted based on the latest archaeological records comprising Global Positioning System (GPS) measurements and field observations, and validated against modern satellite terrain data in a Geographic Information System (GIS). Refined estimates of length and gradient are proposed, along with a reassessment of all channel observations, bridges and tunnels along the system. It is found that the total length of the aqueducts would have been around 426 km if they operated as a single system, and up to 565 km if they continued in parallel all the way to Constantinople; the gradient of the system would have been well below 0.1% throughout, decreasing from upstream to downstream, with steeper slopes only at the intakes. To estimate reasoned inflow conditions for the Water Supply intakes at the time of its operation, modern spring flow records are investigated, and climatic changes from the Early Byzantine period are studied by means of Macrophysical Climate Modelling (MCM). Monthly and daily resolutions are addressed: monthly inflow data can capture the extent of the seasonal variations that may have occurred at the springs, accounting for karst hydrogeology; daily inflow data allows the study of flow attenuation in the Water Supply in the short term. Simplified models and engineering judgement are employed to recreate monthly and daily inflow series from limited modern data for karstic springs and weather stations in Thrace. The results from GIS mapping, combined with the proposed inflow scenarios, are used to develop open-channel flow modelling of the Water Supply at a global scale. Aqueduct flow is numerically simulated by means of both steady (monthly) and unsteady (daily) analysis using the river modelling software HEC-RAS. The system capacity and hydraulic performance are studied for the fourth and fifth century aqueducts operating either as parallel lines or joining into a single system. An estimation of water delivered to Constantinople is proposed for typical dry, average and wet years. Results of this work are employed in a parallel research investigation on the management and distribution of water within the ancient city.

Before this research study began, relatively little was understood of the water supply in Constantinople, particularly within the walls of the city. Archaeological work had focused on collecting details of 160 cisterns and a small number of channels and pipes were incidental finds in other excavations. Although no-one had considered the water supply in Constantinople as a whole, the evidence seemed to indicate a sophisticated water management system. With the available data fragmented, and the potential for more evidence limited to serendipitous finds associated with construction work, the only way to move the understanding of the water supply forward is to take a radically different perspective: civil engineers are well placed to envisage the water supply as a working system and make use of their modern design skills and tools to fill in the gaps between the fragmented data. This reimagining of the water supply system was driven by a key piece of knowledge: the water supply worked, and worked for many centuries. That fact, combined with the fragments of physical and literary evidence, the largely unchanged landscape and the fundamental physical laws governing gravity-fed water systems, are enough to start filling in the information to create a complete system. The core work in reimagining the water supply system has been developing an understanding of the physical infrastructure of the distribution system. Although the two most recent and comprehensive studies appeared to agree that there were about 159 cisterns in the city, close examination of the available data showed that there were actually 209 with the possibility of more. An evaluation of the aqueduct routes in previous studies highlighted inconsistencies with newly available evidence: alternative routes were designed that tied together the available evidence, providing a consistently downhill route, shorter and more straightforward to construct. Having established the number and spread of cisterns and the locations of the aqueducts, it was possible to create a network delivering water from the aqueduct channels to the cisterns for collection by the public. Consideration has also been given to what occurs at either end of this physical infrastructure. At the upstream end, quantifying and characterising the water source defines the water available to distribute and helps to indicate the purpose of the cisterns. At the downstream end, developing even a basic model of water consumption has enabled the distribution network to move from a static artefact to a system with a quantifiable purpose. The combination of the physical infrastructure, inflow data and demand assumptions in an agent-based model demonstrate that the decisions and assumption made within each element work together and allow a fourth element, management, to be considered. The agent-based model of the water supply enables consideration of a dynamic system and the exploration of a number of 'what if?' scenarios. This exploration concludes that the cistern-based distribution system probably developed because of fluctuations in inflow. It may have been possible for the city to use a merged arrangement on the Aqueduct of Valens inflow, but the burden of pro-active management required to make it successful suggests that a parallel arrangement is more likely. There was likely to be an interconnection between the two main aqueducts, which would have enabled the use of water stored in the largest open-air cisterns.
