Authors: Figueirêdo Antonio Fábio Reis , Calasans Neylor Alves 
Published: August 2018

Com o objetivo de orientar o plano de manejo da bacia hidrográfica do rio Colônia, foi gerado um mapa de risco de salinização de solos. Considerando-se que o processo de salinização é resultado da interação de diversos fatores, o referido mapa foi gerado tendo como base mapas de clima, solos, condutividade elétrica da água, malha hídrica, declividade e cobertura vegetal. Todos os mapas foram gerados no ArcView 3.2a, que é um SIG (Sistema de Informações Geográficas), na escala de 1:500000, com resolução espacial de 30 metros. Para a definição dos pesos dos critérios, foi utilizada a técnica de análise multicritério AHP (Analytical Hierarchy Process). Foram geradas quatro classes de risco de salinização de solos, onde 9,62% da área da bacia hidrográfica do rio Colônia corresponde à classe de baixo risco de
salinização, 35,53% a médio risco de salinização, 39,86% a alto risco de salinização e 14,99% da área da bacia corresponde a risco muito alto de salinização do solo. lt;/span>

The floods in urbanized areas damage systemically the Brazilian municipalities during the highraining periods. The economic lost that the nation face with this phenomenon are not yet measured, althoughthrough the impacts’ extension it is possible to observe that they are affecting the South and Southeastregions during this decade. Disasters within the urban tissue are complex, as they turn the various types ofrisks in a mess, mixing the natural risks with the social ones and also with the technological and biologicalrisks. If society occupies inadequate areas like the floodplains of the rivers and change the hydrologicalregime of the river basins, they pay a higher price, both with the public works to control these floods, andwith the losses generated with floods and their aftermath. So, controlling a flood means intervene in severalprocesses and involved elements, trying to minimize their effects. The recognition and monitoring of areassubject to risk are indispensable tools to for avoiding or reducing the undesired effects and the measures thatassist the management of flooded areas are: maintenance, structural and non structural measures.This article objective is to study the potentialities of the non structural measures to combat the accidentsrelated to floods, through a local research. These measures can be adopted by the architects and urban planners and engineering professionals and collaborate in a systemic and efficient form to decrease these natural disasters damages and frequency.The first methodological procedure used for this research was the survey of actions and public worksimplemented in European, Asian and American cities during the last decade and analyze the probabilityof adapting these works to the Brazilian reality. These research findings are important subsidies for thepublic policies and urban projects development so that they minimize the urban floods, thus helping thesustainable development.

Published: August 2018

A água deverá tornar-se, ao longo do século XXI, um recurso natural tão importante e disputado do ponto de vista econômico, social, ambiental e político, da mesma forma, que o carvão e o petróleo ocuparam o cenário na economia mundial, social e política ao longo dos últimos 150 anos. No Brasil, a produção de petróleo offshore obriga o treinamento contínuo de pessoal no combate a incêndios em instalações petrolíferas. O Centro de Treinamento, objeto deste trabalho, treina anualmente mais de 7.000 pessoas gerando, consequentemente, um consumo elevado de água. No passado esta água era proveniente de uma reserva natural e atualmente o reúso, através de tecnologias simplificadas reduz a demanda sobre esses mananciais de água visando o combate ao desperdício. O presente trabalho avaliou numa visão crítica os processos de reúso de uma maneira geral e mais precisamente em Centro de Treinamento de Combate a Incêndio onde o treinamento consome considerado volume de água como agente extintor. Desta forma, é fundamental pensar e praticar o reúso da água. Isto remete à necessidade precípua de poupar, reduzir, reciclar e desenvolver processos de reúso que não venham na contramão da sociedade, ou seja, estejam baseadas nos princípios da precaução, considerando a possibilidade de ocorrências de contaminações de ordem química e microbiológica presentes nos efluentes.

Published: August 2018

Most commercial process simulators have its origin at the petrochemical industry and their use in other sectors depends on testing. In this context a model of an industrial column system of bioethanol distillation heated by direct injection of vapor was developed and implemented using the simulator Aspen HYSYS, which was compared with experimental data obtained in the industrial plant. The system basically consists of four columns heated by direct vapor injection and the model of the system was developed using this approach together with the simulation blocks for columns heated by reboilers available on Aspen HYSYS. For such a task it was admitted a null termal load for the reboiler and a direct vapor stream was added in the side of the column. Overall deviations between simulated values and those measured in the distillery were 2.3 % for temperatures, 12.95 % for concentrations, and 1.07 % for bioethanol production in the industrial distillation system (IDS). The low values of the deviations obtained when comparing the data of the real process with simulated data indicate that IDS is well sized and the model implemented as well as the process simulator adopted can be used in the sugar-ethanol industry with distillation columns heated by direct injection of vapor.
SIMULAÇÃO NUMÉRICA NÃO-LINEAR DO COMPORTAMENTO DE PLACAS DE AÇO PERFURADAS SOB COMPRESSÃO UNIAXIAL EM ESTRUTURAS NAVAIS E OFFSHORE
Authors: Baptista Lillian Gonçalves , Real Mauro De Vasconcellos 
Published: August 2018

Placas são elementos estruturais de superfície plana amplamente empregados em engenharia, cuja espessura é pequena quando comparada com as demais dimensões. Estas estruturas laminares podem ser delimitadas por linhas retas, denominadas enrijecedores, formando parte integrante de estruturas de navios, plataformas de petróleo offshore, comportas e docas flutuantes. É muito comum encontrar perfurações nessas placas para inspeção e manutenção, e o tamanho desses furos tem significativa importância no desempenho da estrutura. Uma análise não-linear da flambagem com base no método dos elementos finitos, considerando-se as imperfeições geométricas iniciais e as não-linearidades do material, foi realizada para um grupo de 150 placas onde a largura é mantida constante e o comprimento é variado, assim como a espessura e o diâmetro do furo circular centralizado. A modelagem computacional foi realizada no software ANSYS, onde foi possível obter a carga de ruptura última para cada modelo e analisar a influência do tamanho do furo, da esbeltez e do comprimento variável na capacidade de carga das placas. Ficou evidente que a força máxima é significativamente reduzida pelo furo. Nota-se também que quanto mais espessa a placa, maior sua resistência, que a capacidade de carga é raramente afetada com a variação de seu comprimento.

Published: August 2018

As oleaginosas vêm sendo uma importante alternativa ao uso do petróleo como matéria-prima para combustíveis. A extração de óleo de mamona é um elo de fundamental importância sobre a cadeia produtiva do biodiesel, principalmente no Nordeste do Brasil. Juntamente com a torta e a casca, co-produtos da extração, podem contribuir para reduzir a pobreza nas regiões semiáridas do Brasil. A mamoneira é uma oleaginosa de alto valor econômico, cujas aplicações são bastante várias, dando origem a produtos variados, que vão desde a fabricação de graxas e lubrificantes, tintas, vernizes, espumas e materiais plásticos para diversos fins, até a produção de cosméticos, produtos alimentares, farmacêuticos e o biodiesel. Além disso, o processamento desta oleaginosa vem gerando impactos sociais significativos por ser produzida dentro do conceito de agricultura familiar. O objetivo principal deste estudo foi fornecer subsídios aos agricultores familiares de cooperativas do Pólo São Francisco para avaliação dos custos e benefícios da comercialização do óleo e torta em lugar do grão de mamona. Para isto foi realizada a otimização do processo de extração por solvente do óleo a partir do grão de mamona produzido pelas Cooperativas e também uma análise econômica comparativa entre a comercialização do grão e do óleo extraído. Os resultados obtidos permitem concluir que a qualidade do óleo da semente de mamona do tipo BRS Paraguaçu, cultivada pelas cooperativas, tem qualidade satisfatória relativa à sua estabilidade à oxidação e índice de acidez, além de prever vantagem em comercializar o óleo de mamona em relação à comercialização do grão, com aumento da margem de lucro de 67 para 81%. A margem aumenta para 126% quando levada em consideração a comercialização da torta.
Biomass Gasification for Power Generation: A Comparison with Steam Boilers in the Brazilian Scenario
Authors: Miguel João , Filho Tiberio , Pereira Ricardo , Maturana Aymer 
Published: August 2018

This work compares biomass gasification and conventional direct combustion in steam boilers for producing power in the context of Brazilian sugar cane mills. The objective of this technical report is to show that gasification could be a more attractive way to convert biomass in energy, compared to using steam boilers, which in some cases can show a low efficiency. The idea is to use the gasifiers in sugarcane mills that have low pressure boilers (21 to 42 kgf/cm2) that are currently dedicated only to generate steam or electrical power for the mill own energy consumption. The results shows that gasification could be a cost-effective alternative for power production in Brazilian sugar cane plants with some additional advantages like the bagasse usage between the season and off-season periods to maintain a constant power generation throughout the entire year, higher energy availability and efficiency. However, nowadays in Brazil the economic advantage of gasification depends highly on political support and reliable long-term stable political framework conditions with an enough timeframe for the development, construction and operation of biomass gasification plants.

Published: August 2018

This paper presents a detailed design of an on-grid PV system that meets the electrical needs of a typical domestic building in the southern corner (i.e. Khulna) of Bangladesh. The system comprising of the photovoltaic array to capture solar energy, a power converter to change over between AC and DC, grid connection and lead acid battery to store energy. The modelling is completed by assessing the required load, choosing and deciding the proper specifications of the components associated with the system. Different factors, for example, the geographic area, atmospheric condition, solar irradiance and load consumption upon which the whole work depends are all considered. The cost optimization of the system is performed as per the system’s net present cost, cost of energy, operating expense and initial capital. Additionally, an efficient algorithm to manage the system energy along with power flow is proposed. The techno-economic analysis of the proposed system is performed by using HOMER simulation software. Simulated results indicate that the proposed model meet the load demand and show tasteful execution.
Analysis of yield stress ratio and overconsolidation ratio as parameter determination preconsolidation in eemian gyttja
Authors: Malinowska Edyta E. , Bajda Marek 
Published: August 2018

Abstract
The preconsolidation stress is an important phenomenon that determines the value of stress history exerted in the past on the subsoil in the geotechnical engineering. Overconsolidation ratio (OCR) is one of the main criteria conditioning soil behaviour and its characteristics. Here thought, the yield stress ratio (YSR) is used to determine the value of preconsolidation stress resulting from mechanical overburden than can be changed by many post depositional processes like secondary and tertiary compressibility, cementation, aging, temperature change and others. The yield stress ratio (YSR) is defined as the relationship between vertical yield stress (σ’vy) to the effective vertical stress (σ’v0). The eemian gyttja was used as a foundation in the engineering construction. In practical geotechnical engineering, evaluation of stress history is usually based on the overconsolidation ratio (OCR). The yield stress ratio (YSR) was used in the laboratory as one of the basic parameters for the geotechnical design of the structure. To know the relation between geological background, history and mechanical behaviour in long-time process of the soil aims a knowledge that can help engineers who often have to predict soil behaviour based upon the soil geological history and a few geotechnical data. In order to evaluate the yield stress ratio of eemian gyttja it is necessary to restore this soft, organic soil as much as possible to the in situ conditions. The laboratory tests were used to determinate the vertical yield stress and then the yield stress ratio. The laboratory tests were made in the automatic oedometer and the in situ tests were carried out on the dilatometer test (DMT). The comparison between the determination the yield stress ratio of eemian gyttja from the laboratory and the overconsolidation ratio from in situ test has been done. The studies have shown that the values of the overconsolidation ratio determinate from the laboratory tests are a little higher than determinate from the in situ tests.
