description Publicationkeyboard_double_arrow_right Master thesis 2019 PortugalAuthors: Medeiros, Camila Santos;As alterações climáticas são já há algumas décadas consideradas uma ameaça real às cidades, que via de regra não estão preparadas para lidar com a incerteza que caracteriza o referido fenômeno, tampouco com seus impactos. Nas cidades costeiras essa ameaça é ainda maior em função de fenômenos como a elevação do nível médio do mar e as alterações nos padrões de precipitação intensa de curta duração, que aumentam exponencialmente o risco de inundação destes territórios, ameaçando a sua manutenção e desenvolvimento no futuro. Sendo os sistemas de transporte uma das estruturas principais para o funcionamento de uma cidade, a vulnerabilidade destes à momentos de inundação, pode determinar um alto risco para suas funções básicas. O que este trabalho pretende é abordar a vulnerabilidade dos sistemas de transporte às inundações em cidades costeiras; como os impactos das alterações climáticas são ou serão capazes de alterar os padrões de mobilidade em uma cidade; e como é possível responder a estas incertezas através dos processos de adaptação para a resiliência, com exemplos práticos de cidades que tiveram que lidar com estas questões em situações pós-desastre. Climate change has for some decades been considered a real threat to cities, which are mostly not prepared to deal with the uncertainty that characterizes this phenomenon, nor with its impacts. In coastal cities, this threat is even greater because of phenomena such as the rise in mean sea level and changes in the patterns of intense short-term precipitation that exponentially increase the risk of flooding of these territories, threatening their maintenance and development in the future . In the other hand, transport systems are one of the main structures for the operation of a city, so their vulnerability to flooding can determine a high risk for one of the basic urban functions. What this paper intends is to address the vulnerability of flood transportation systems in coastal cities; how the impacts of climate change are or will be able to change the mobility patterns in a city; and how these uncertainties can be addressed through adaptive processes for resilience, with practical examples of cities that have had to deal with these issues in post-disaster situations.

A Ilha do Porto Santo situa-se no Arquipélago da Madeira, em pleno Oceano Atlântico. A sua ocupação é um processo que dura há cerca de 600 anos, sendo que o seu resultado pode hoje ser observado: Um território pouco potenciado no aproveitamento da sua paisagem. A presente proposta de projecto final de mestrado versa sobre a ocupação desta ilha numa óptica de sustentabilidade ecológica e equilíbrio futuro.Todas as feridas que ao longo dos anos foram causadas neste território influenciaram o crescimento ecológico, cultural e económico da ilha. De que forma pode, então, a ilha do Porto Santo ser sustentável, sem as condicionantes da ocupação incial? Abordando vários casos de estudo de Ilhas em condições semelhantes, este trabalho direcciona-se gradualmente para a ilha em questão, propondo uma nova forma de habitar, com a pretensão de contribuir para a revitalização da vertente ambiental do território. Assim, faz-se conviver a ocupação Humana com as energias renováveis, a alimentação a partir da agricultura e a nova arquitectura vernacular, numa lógica de conjunto. O Laboratório da Paisagem é a relação simbiótica entre o Homem, a energia e o território. ABSTRACT: The Island of Porto Santo is located in Madeira archipelago in the Atlantic Ocean. It’s ocupation is a process that lasted for about 600 years and its result can now be observed: A territory not much enhanced in the use of its landscape. The present proposal of the final master project deals with the occupation of this island in a perspective of ecological sustainability and future equilibrium. All the wounds that were (that have been) caused to this territory over the years has (have) influenced the ecological, cultural and economic growth of the Island. In what way (how) can the Island of Porto Santo become ecologically balanced and sustainable, without the constraints of the initial occupation? Addressing several case studies of islands under similar conditons, this work gradually moves towards the island in question, proposing a new way of inhabiting with the aim of contributing to the revitalization of the environmental side of the territory. Thus, as a whole, it is possible to coexist the human occupation with renewable energy, food from local agriculture and new vernacular architecture. The Landscape Laboratory is the symbiotic relationship between Man, energy and territory. N/A

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2022 BrazilPublisher:Universidade Federal do Rio Grande do Norte Authors: Fonseca, Thales Queiroz;Factors such as environmental restrictions and technological advances have enabled the insertion of renewable energy sources (e.g. photovoltaic and wind systems) as distributed generators (DG), in the electrical grid. However, because of the intermittent nature of the energy in solar radiation and wind, control strategies for regulating the DG power flow are necessary to ensure a proper connection of these systems to the grid. These control strategies are applied to the DG and the grid interface, which is implemented by grid-connected power converters. Grid-connected power converters can be controlled to operate as a controlled current source (grid-feeding converters) or as a controlled voltage source (grid-forming converters), in which the grid-feeding power converter (GFD-PC) systems are suitable to deliver power to an energized grid, while grid-forming power converter (GFO-PC) systems can contribute for regulating the grid voltage and frequency. When connected to a low voltage grid, GFD-PC systems can cause voltage deviation in the grid, and GFO-PC systems are subject to active and reactive power coupling. These drawbacks can be overcome with the use of the virtual impedance concept, which is a technique that can change the output impedance of power converters. Therefore, it can modify the equivalent impedance between the power converter and the grid, thus improving the power flow control of GFO-PC, and achieving voltage support of GFDPC systems. In this direction, this doctoral thesis proposes implementations of virtual impedances to overcome the drawbacks of GFO-PC and GFD-PC systems connected to the low voltage grid to meet the requirements of power flow control in DG systems. ; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES ; Fatores como restrições ambientais e avanços tecnológicos têm possibilitado a inserção de fontes de energias renováveis (por exemplo, sistemas fotovoltaicos e eólicos), na forma de geradores distribuídos (GD), na rede elétrica.

Nanozeolites have been used as solid supports for enzymes and proteins immobilization, mainly due to their physicochemical properties such as large external surface area, high dispersibility and easy adjustment of their tunable surface properties, especially regarding the surface charge and hydrophilicity/hydrophobicity properties. The main goals of this research work were the syntheses and physicochemical characterization using specific spectroscopic techniques of the nanozeolites (titanosilicalite (Nano-TS1), gismondine (Nano-GIS), (Nano-LTA), beta (Nano-BEA), and faujasite (Nano-X) and also the modulation of their surface physicochemical properties by ion exchange experiments with transition metal cations (Mn2+, Cu2+, Co2+, Zn2+ e Ni2+) and/or by functionalization of their surfaces with organic agents such as aminosilanes and glutaraldehyde. The zeolitic materials were used as a solid supports for the immobilization of fungal Rhizomucor miehei (RML) and Thermomyces lanuginosus (TLL) lipases and the catalytic potential of these nanozeolite-enzyme complexes were explored in the transesterification reactions of oil palm oil and microalgae aiming the biodiesel production for biodiesel production using ethanol as solvent. The results have indicated the nature and concentration of the divalent cations solutions have played a significant role and strongly affected the amount and the enzymatic activity of the immobilized enzymes. The best catalytic performance were obtained with the TLL enzyme immobilized on Nano-X supports ion exchanged with nickel sulfate 0.5 mol.L-1 (Nano-X/Ni/0.5M-TLL). The FAEE yields obtained with Nano-X/Ni/0.5M/TLL complexes were above 94% and a strong synergetic effect was detected for this system, since the equivalent amount of the TLL enzyme in its free form has yielded only 9.1% of ethyl esters. Physicochemical characterization of the zeolite-enzyme complexes by transmission ... Nanozeólitas têm sido exploradas como suporte para a imobilização de enzimas e proteínas devido as suas propriedades físico-químicas, tais como a grande área de superfície externa, a alta dispersibilidade e a facilidade de modulação das suas características de superfície, especialmente, em relação à carga da superfície e propriedades de hidrofilicidade/hidrofobicidade. O presente trabalho teve como objetivos principais as sínteses e caracterização das nanozeólitas (titanosilicalita (Nano-TS1), gismondina (Nano-GIS), A (Nano-LTA), beta (Nano-BEA) e faujasita (Nano-X)) e a modulação de suas propriedades físico-químicas por meio de experimentos de troca iônica com cátions de metais de transição (Mn2+, Cu2+, Co2+, Zn2+ e Ni2+) ou funcionalização de suas superfícies por agentes orgânicos como aminosilanos ou glutaraldeído. Na sequência, foi realizado o estudo desses suportes zeolíticos como matrizes sólidas para a imobilização de lipases e o estudo do potencial catalítico desses complexos nanozeólitas-enzimas na reação de transesterificação para a produção de biodiesel usando diferentes fontes de matérias primas, tais como o óleo de palma e o óleo de microalgas via rota etílica com o uso das lipases de Rhizomucor miehei (RML) e Thermomyces lanuginosus (TLL), os resultados indicaram que as espécies de cátions divalentes e a concentração molar da troca iônica dos suportes nanozeolíticos influenciaram na interação da enzima com a matriz de imobilização e, consequentemente, a atividade enzimática. Em termos catalíticos, os resultados mais relevantes foram obtidos para a enzima TLL, imobilizada no suporte Nano-X e trocada com 0,5 mol.L-1 de sulfato de níquel (Nano-X/Ni/0.5M-TLL). Os rendimentos de ésteres etílicos de ácidos graxos (FAEE) foram acima de 94%, ao passo que, para a mesma quantidade de enzima na sua forma livre, o teor obtido foi de apenas...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) ; The use of biodiesel as an alternative to fossil fuels has been increasing in recent years. Since each ton of biodiesel is generated 100 kg of glycerol, there is some concern about the destination of this byproduct, as its disposition is economically expensive and its market value is low. This way, a solution to this problem is the use of glycerol as a source of carbon in the production of biosurfactants. Despite the numerous advantages of biosurfactants, such as low toxicity, biodegradability and high stability, these compounds are not widely used due to the high cost of production. The application of alternative carbon sources can contribute to reduce production costs and increase the commercial use of biosurfactants. The aim of this research was to analyze the potential of Biodiesel glycerol as carbon source in the production of rhamnolipids from Pseudomonas aeruginosa LBI 2AI. Five samples of glycerol, including treated and untreated, were evaluated. The experiments were conducted in flask and Bioreactor. The 1L Erlenmeyer flask containing 300 mL of culture medium were incubated in a rotary shaker for 120 hours at 37°C and 200 rpm. Cultures in 13L bioreactor with 4L of culture medium were carried out for 160 hours at 37°C. The agitation speed varied between 300-900rpm in order to maintain pO2 in 5%. To improve the biosurfactant concentration, fed-batch culture was performed witch up to three pulses of glycerol feeding, inceasing the concentration of the medium by up to 30% of initial. The results show that Pseudomonas aeruginosa LBI 2AI was able to produce rhamnolipídios from residual glycerol from Biodiesel production in the strategies used in this study. Bioreactor cultures enabled an increase in the concentration of the product formed, using the treated and untreated Glycerol residues. Promising concentrations of rhamnolipids using these carbon sources were achieved increasing the concentration. ; A utilização do biodiesel como alternativa em ...

Várias Conferencias das Partes (COP) foram realizadas, definindo ações e metas a serem cumpridas pelas nações, que visem valorizar os ecossistemas e a reduzir a extinção de espécies, garantindo a diversidade genética; o uso sustentável da biodiversidade e o reconhecimento real do custo dos serviços ecossistêmicos prestados à sociedade; a repartição de benefícios do uso dos recursos genéticos junto as suas comunidades de origem, incluindo suas sequencias digitais; a disponibilização de recursos financeiros relevantes para garantir a capacitação e a cooperação técnica e científica; e, o acesso a transferência de tecnologia de forma equitativa à todos os países. Todas elas pressupõem o uso de tecnologias e sua disseminação para as populações locais, além de ações no marco do conceito de Bioeconomia. O presente texto procura trazer referências para questões que envolvem os usos dos recursos biológicos, a biodiversidade, e o uso econômico, a bioeconomia, e sugere uma reflexão: se a parceria é legítima, qual o melhor modelo? Abstract: Biodiversity conservation, a subject that was previously distant from the Brazilian society, is addressed in different international forums, led by the United Nations (UN) notably in the Convention on Biological Diversity (CBD). Several Conferences of the Parties (COP) were held and defined actions and goals to be met by nations, which aim to value ecosystems and reduce the extinction of species, guaranteeing genetic diversity; the sustainable use of biodiversity and the real recognition of the cost of ecosystem services provided to society; the sharing of benefits from the use of genetic resources with their communities of origin, including their digital sequences; the provision of relevant financial resources to guarantee training, technical and scientific cooperation; and, equitable access to technology transfer to all countries. All of them require the use of technologies and their dissemination to local populations, in addition to actions within the framework of the bioeconomy concept. This text seeks to bring references to issues involving the use of biological resources, biodiversity, and its economic use, bioeconomy, and suggests a reflection: if the partnership is legitimate, what would be the suitable model?

The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly due to long periods of storage. Because of this, the oxidation stability has been the focus of numerous researches since it directly affects the producers, distributors and users of fuel. One of the possibilities to increase the resistance of biodiesel is the autoxidation treatment with inhibitors of oxidation. The antioxidants can be used as potential inhibitors of the effects of oxidation on the kinematic viscosity and the index of acidity of biodiesel, thereby increasing oxidative stability. This work aims to examine the efficiency of antioxidants, α-tocopherol and butylated hydroxy-toluene (BHT), added the biodiesel content of remembrance through Pressurized-Differential Scanning Calorimetry (P-DSC), Thermogravimetry (TG) and Petrology. The results showed that the use of antioxidant BHT, at the concentration of 2000ppm, increased resistance to oxidation of the biodiesel and oxidative induction time (OIT), which is a better result as antioxidant than the α-tocopherol. With the thermogravimetric analysis, it was observed that the biodiesel presented an initial decomposition temperature of lower tendency than that of oil, demonstrating to be more volatile, bearing great similarity to the diesel and being characterized as an alternative fuel. The rheological analysis indicated that each sample of biodiesel behaved as a Newtonian fluid ; O biodiesel é definido como o derivado mono-alquil éster de ácidos graxos de cadeia longa, proveniente de fontes renováveis como óleos vegetais ou gordura animal, cuja utilização está associada à substituição de combustíveis fósseis em motores ciclo diesel.

The Third Sector Institutions have acquired an important role on the society through the years, with new demands that have been given to them in financial and human terms. Manny studies were made under the sustainability of PISS (Private Institutions of Social Solidarity). However, this study is going to be focused on Cerebral Palsy PISS’s, where economic and financial problems still persist. Also, this is a very sensible area of the society where resources are scarce due to the lack of economic and financial support. The main objective of this study is to determine which factors may put in cause the sustainability of the PISS’s. Several methods were utilized to determine the statistics of our analysis. Those are, the quantitative method, a series of questionnaires and the analysis of multiple data that was available to us. In this study we also pretend to verify which factors may lead to the loss of sustainability of this Institutions, the risks zones they face, in the area of Cerebral Palsy. These areas are their own indebtedness, the marking of possible areas on where value can be generated, the formulation of possible suggestions, and the prioritization of transformation programs. In general, the factors that have contributed to the economic vulnerability of this PISS’s are according with the respondents, and in the majority of the cases, related with their own management and their economic and financial aspects. Also, with this study, we pretend to innovate, creating guidelines and limiting sustainability risk zones. These guidelines aim to serve in the future, several PISS managers and technicians, with the intent of detecting this referred symptom’s, which may lead these Institutions to an economic default and also to a state of bankruptcy. Due to the fact of these Institutions being highly dependent from Public State economic support, is required from their leader’s several innovative measures, as much in human and technical terms, measures which allow them to be self-sustainable and at the same time permitting these agents to be important in the social intervention, with significant impact on the underprivileged populations. As Instituições do Terceiro Setor têm vindo a adquirir um importante papel na Sociedade ao longo dos tempos, com novas exigências lhe são impostas, tanto em recursos humanos como financeiros. Muitos estudos se têm vindo a realizar no âmbito da Sustentabilidade das IPSS. No entanto, este irá abranger o Setor das IPSS de Paralisia Cerebral, Instituições onde os problemas económico-financeiros são determinantes, e também por ser um uma das áreas mais sensíveis da Sociedade, onde os recursos são escassos. O objetivo principal deste estudo é o de saber quais os fatores que poderão pôr em causa a Sustentabilidade das IPSS de Paralisia Cerebral. Para isso utilizou-se o método quantitativo, através de um questionário por Inquérito e pela análise dos Balanços e das Demonstrações de Resultados, por forma a completar, em termos estatísticos, a nossa análise. Da interpretação desses resultados pretende-se determinar quais os fatores da perda da Sustentabilidade destas IPSS, quais as zonas de risco que enfrentam, nomeadamente o endividamento, identificar as áreas passíveis para a Criação de Valor, formular possíveis recomendações e priorizar iniciativas para a implementação de um programa de transformação. Os fatores que de uma maneira geral que contribuíram para a vulnerabilidade financeira destas IPSS segundo os participantes inquiridos, estão na grande maioria dos casos, relacionados com sintomas relativos com a parte económico-financeira e de gestão. Com este estudo, também se procurou inovar, criando um quadro orientador e limitador das zonas de risco de perda de sustentabilidade, mapa esse que poderá servir no futuro aos gestores e técnicos das IPSS, para detetarem o aparecimento de tais sintomas, os quais podem levar as Instituições a situações de incumprimento e eventualmente a um estado de falência. A situação de subsídio dependência em relação ao Estado, requer por parte dos dirigentes a adoção de novas medidas inovadoras, quer em termos técnicos quer humanos, que lhes permitam serem autossustentáveis, continuando a serem agentes importantes na intervenção social, com impacto significativo junto das populações mais desfavorecidas.

Such preference is justified by landscape and aesthetic's value, as well as the need for recreation and leisure activities of individuals. The tourism industry, aiming profitability, appropriates themselves of such reality by means of a discourse based on sustainability. Such scenario has already reached the State of Sergipe, which has a diversity of splendiferous landscapes and a cultural diversity that express tourist potentialities. Vaza-Barris estuary is engaged in this context, since it has been touristic explored, specifically, after the construction of Orla Pôr do Sol (Sunset Edge) and Joel Silveira's brigde. In this sense, the activities that occur in the estuary, specifically, on Pôr-do- Sol Orla, Ilha da Paz (Island of Peace), and Ilha Paraiso (Paradise Island), are being damaged by touristic activities and these places don't have any kind of management plan, which has been compromising the local sustainability. In this context, this study aimed to analyze the sustainability of tourist's activities developed at the estuary of Vaza-Barris’s River, since these Islands are areas of intense touristic visitation as well as they are considered Permanent Preservation Areas (APP's) but they don't present until now any kind of management plans. As methodology we used exploratory research, documentary and bibliographic, and data collection instruments such as: questionnaires, observation of the study area and semi-structured interviews with the residents of the locality and Public bodies. Reach the conclusion that the systematic examination of the relationship between the General Law of Tourism, public policies for sustainable tourism in Sergipe State and the reality of tourism in the Mosqueiro Village hasn't showed favorable trends for sustainability, being necessary a intervention from the public bodies of tourism and the public bodies of environmental government in order to elaborate a plan for public use of this places as well as it is ...

Não recebi financiamento ; A energia fotovoltaica vem ganhando cada vez mais espaço na matriz energética brasileira. Sendo assim, levantou-se a hipótese de utilizar espaços remanescentes de Universidades Públicas, onde geralmente são deixados de lado por serem uma grande área em desuso, para instalação de uma usina fotovoltaica. Onde o principal foco é a instalação de uma usina de minigeração fotovoltaica distribuída compartilhada. Os campus a serem estudados no decorrer da análise, foram três campus da Universidade Estadual Paulista - UNESP, sendo eles: Itapeva, Ourinhos e Rosana, na qual, suas áreas disponíveis são respectivamente 32,4 mil m², 65,13 mil m² e 37,77 mil m². Nestas áreas apresentadas, é possível instalar usinas de até 6,91MW, 13,86MW e 8,04MW. Ou seja, temos que todos os campus atingiriam uma potência maior de 5MW, na qual seria possível a instalação de uma usina para minigeração e ainda haveria espaço suficiente para ampliação do sistema, ou ainda criação de uma usina híbrida. ; Photovoltaic energy has been gaining more and more space in the Brazilian energy matrix. Therefore, the hypothesis was raised of using remaining spaces of Public Universities, where they are usually left aside because they are a large area in disuse, for the installation of a photovoltaic plant. Where the main focus is the installation of a shared distributed photovoltaic minigeneration plant. The campuses to be studied during the analysis were three campuses of Universidade Estadual Paulista - UNESP, namely: Itapeva, Ourinhos and Rosana, in which their available areas are respectively 32.4 thousand m², 65.13 thousand m² and 37 .77 thousand m². In these areas presented, it is possible to install plants of up to 6.91MW, 13.86MW and 8.04MW. That is, we have that all campuses would reach a power greater than 5MW, in which it would be possible to install a plant for minigeneration and there would still be enough space for expansion of the system, or even the creation of a hybrid plant.

description Publicationkeyboard_double_arrow_right Master thesis 2019 PortugalAuthors: Medeiros, Camila Santos;As alterações climáticas são já há algumas décadas consideradas uma ameaça real às cidades, que via de regra não estão preparadas para lidar com a incerteza que caracteriza o referido fenômeno, tampouco com seus impactos. Nas cidades costeiras essa ameaça é ainda maior em função de fenômenos como a elevação do nível médio do mar e as alterações nos padrões de precipitação intensa de curta duração, que aumentam exponencialmente o risco de inundação destes territórios, ameaçando a sua manutenção e desenvolvimento no futuro. Sendo os sistemas de transporte uma das estruturas principais para o funcionamento de uma cidade, a vulnerabilidade destes à momentos de inundação, pode determinar um alto risco para suas funções básicas. O que este trabalho pretende é abordar a vulnerabilidade dos sistemas de transporte às inundações em cidades costeiras; como os impactos das alterações climáticas são ou serão capazes de alterar os padrões de mobilidade em uma cidade; e como é possível responder a estas incertezas através dos processos de adaptação para a resiliência, com exemplos práticos de cidades que tiveram que lidar com estas questões em situações pós-desastre. Climate change has for some decades been considered a real threat to cities, which are mostly not prepared to deal with the uncertainty that characterizes this phenomenon, nor with its impacts. In coastal cities, this threat is even greater because of phenomena such as the rise in mean sea level and changes in the patterns of intense short-term precipitation that exponentially increase the risk of flooding of these territories, threatening their maintenance and development in the future . In the other hand, transport systems are one of the main structures for the operation of a city, so their vulnerability to flooding can determine a high risk for one of the basic urban functions. What this paper intends is to address the vulnerability of flood transportation systems in coastal cities; how the impacts of climate change are or will be able to change the mobility patterns in a city; and how these uncertainties can be addressed through adaptive processes for resilience, with practical examples of cities that have had to deal with these issues in post-disaster situations.

A Ilha do Porto Santo situa-se no Arquipélago da Madeira, em pleno Oceano Atlântico. A sua ocupação é um processo que dura há cerca de 600 anos, sendo que o seu resultado pode hoje ser observado: Um território pouco potenciado no aproveitamento da sua paisagem. A presente proposta de projecto final de mestrado versa sobre a ocupação desta ilha numa óptica de sustentabilidade ecológica e equilíbrio futuro.Todas as feridas que ao longo dos anos foram causadas neste território influenciaram o crescimento ecológico, cultural e económico da ilha. De que forma pode, então, a ilha do Porto Santo ser sustentável, sem as condicionantes da ocupação incial? Abordando vários casos de estudo de Ilhas em condições semelhantes, este trabalho direcciona-se gradualmente para a ilha em questão, propondo uma nova forma de habitar, com a pretensão de contribuir para a revitalização da vertente ambiental do território. Assim, faz-se conviver a ocupação Humana com as energias renováveis, a alimentação a partir da agricultura e a nova arquitectura vernacular, numa lógica de conjunto. O Laboratório da Paisagem é a relação simbiótica entre o Homem, a energia e o território. ABSTRACT: The Island of Porto Santo is located in Madeira archipelago in the Atlantic Ocean. It’s ocupation is a process that lasted for about 600 years and its result can now be observed: A territory not much enhanced in the use of its landscape. The present proposal of the final master project deals with the occupation of this island in a perspective of ecological sustainability and future equilibrium. All the wounds that were (that have been) caused to this territory over the years has (have) influenced the ecological, cultural and economic growth of the Island. In what way (how) can the Island of Porto Santo become ecologically balanced and sustainable, without the constraints of the initial occupation? Addressing several case studies of islands under similar conditons, this work gradually moves towards the island in question, proposing a new way of inhabiting with the aim of contributing to the revitalization of the environmental side of the territory. Thus, as a whole, it is possible to coexist the human occupation with renewable energy, food from local agriculture and new vernacular architecture. The Landscape Laboratory is the symbiotic relationship between Man, energy and territory. N/A

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2022 BrazilPublisher:Universidade Federal do Rio Grande do Norte Authors: Fonseca, Thales Queiroz;Factors such as environmental restrictions and technological advances have enabled the insertion of renewable energy sources (e.g. photovoltaic and wind systems) as distributed generators (DG), in the electrical grid. However, because of the intermittent nature of the energy in solar radiation and wind, control strategies for regulating the DG power flow are necessary to ensure a proper connection of these systems to the grid. These control strategies are applied to the DG and the grid interface, which is implemented by grid-connected power converters. Grid-connected power converters can be controlled to operate as a controlled current source (grid-feeding converters) or as a controlled voltage source (grid-forming converters), in which the grid-feeding power converter (GFD-PC) systems are suitable to deliver power to an energized grid, while grid-forming power converter (GFO-PC) systems can contribute for regulating the grid voltage and frequency. When connected to a low voltage grid, GFD-PC systems can cause voltage deviation in the grid, and GFO-PC systems are subject to active and reactive power coupling. These drawbacks can be overcome with the use of the virtual impedance concept, which is a technique that can change the output impedance of power converters. Therefore, it can modify the equivalent impedance between the power converter and the grid, thus improving the power flow control of GFO-PC, and achieving voltage support of GFDPC systems. In this direction, this doctoral thesis proposes implementations of virtual impedances to overcome the drawbacks of GFO-PC and GFD-PC systems connected to the low voltage grid to meet the requirements of power flow control in DG systems. ; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES ; Fatores como restrições ambientais e avanços tecnológicos têm possibilitado a inserção de fontes de energias renováveis (por exemplo, sistemas fotovoltaicos e eólicos), na forma de geradores distribuídos (GD), na rede elétrica.

Nanozeolites have been used as solid supports for enzymes and proteins immobilization, mainly due to their physicochemical properties such as large external surface area, high dispersibility and easy adjustment of their tunable surface properties, especially regarding the surface charge and hydrophilicity/hydrophobicity properties. The main goals of this research work were the syntheses and physicochemical characterization using specific spectroscopic techniques of the nanozeolites (titanosilicalite (Nano-TS1), gismondine (Nano-GIS), (Nano-LTA), beta (Nano-BEA), and faujasite (Nano-X) and also the modulation of their surface physicochemical properties by ion exchange experiments with transition metal cations (Mn2+, Cu2+, Co2+, Zn2+ e Ni2+) and/or by functionalization of their surfaces with organic agents such as aminosilanes and glutaraldehyde. The zeolitic materials were used as a solid supports for the immobilization of fungal Rhizomucor miehei (RML) and Thermomyces lanuginosus (TLL) lipases and the catalytic potential of these nanozeolite-enzyme complexes were explored in the transesterification reactions of oil palm oil and microalgae aiming the biodiesel production for biodiesel production using ethanol as solvent. The results have indicated the nature and concentration of the divalent cations solutions have played a significant role and strongly affected the amount and the enzymatic activity of the immobilized enzymes. The best catalytic performance were obtained with the TLL enzyme immobilized on Nano-X supports ion exchanged with nickel sulfate 0.5 mol.L-1 (Nano-X/Ni/0.5M-TLL). The FAEE yields obtained with Nano-X/Ni/0.5M/TLL complexes were above 94% and a strong synergetic effect was detected for this system, since the equivalent amount of the TLL enzyme in its free form has yielded only 9.1% of ethyl esters. Physicochemical characterization of the zeolite-enzyme complexes by transmission ... Nanozeólitas têm sido exploradas como suporte para a imobilização de enzimas e proteínas devido as suas propriedades físico-químicas, tais como a grande área de superfície externa, a alta dispersibilidade e a facilidade de modulação das suas características de superfície, especialmente, em relação à carga da superfície e propriedades de hidrofilicidade/hidrofobicidade. O presente trabalho teve como objetivos principais as sínteses e caracterização das nanozeólitas (titanosilicalita (Nano-TS1), gismondina (Nano-GIS), A (Nano-LTA), beta (Nano-BEA) e faujasita (Nano-X)) e a modulação de suas propriedades físico-químicas por meio de experimentos de troca iônica com cátions de metais de transição (Mn2+, Cu2+, Co2+, Zn2+ e Ni2+) ou funcionalização de suas superfícies por agentes orgânicos como aminosilanos ou glutaraldeído. Na sequência, foi realizado o estudo desses suportes zeolíticos como matrizes sólidas para a imobilização de lipases e o estudo do potencial catalítico desses complexos nanozeólitas-enzimas na reação de transesterificação para a produção de biodiesel usando diferentes fontes de matérias primas, tais como o óleo de palma e o óleo de microalgas via rota etílica com o uso das lipases de Rhizomucor miehei (RML) e Thermomyces lanuginosus (TLL), os resultados indicaram que as espécies de cátions divalentes e a concentração molar da troca iônica dos suportes nanozeolíticos influenciaram na interação da enzima com a matriz de imobilização e, consequentemente, a atividade enzimática. Em termos catalíticos, os resultados mais relevantes foram obtidos para a enzima TLL, imobilizada no suporte Nano-X e trocada com 0,5 mol.L-1 de sulfato de níquel (Nano-X/Ni/0.5M-TLL). Os rendimentos de ésteres etílicos de ácidos graxos (FAEE) foram acima de 94%, ao passo que, para a mesma quantidade de enzima na sua forma livre, o teor obtido foi de apenas...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) ; The use of biodiesel as an alternative to fossil fuels has been increasing in recent years. Since each ton of biodiesel is generated 100 kg of glycerol, there is some concern about the destination of this byproduct, as its disposition is economically expensive and its market value is low. This way, a solution to this problem is the use of glycerol as a source of carbon in the production of biosurfactants. Despite the numerous advantages of biosurfactants, such as low toxicity, biodegradability and high stability, these compounds are not widely used due to the high cost of production. The application of alternative carbon sources can contribute to reduce production costs and increase the commercial use of biosurfactants. The aim of this research was to analyze the potential of Biodiesel glycerol as carbon source in the production of rhamnolipids from Pseudomonas aeruginosa LBI 2AI. Five samples of glycerol, including treated and untreated, were evaluated. The experiments were conducted in flask and Bioreactor. The 1L Erlenmeyer flask containing 300 mL of culture medium were incubated in a rotary shaker for 120 hours at 37°C and 200 rpm. Cultures in 13L bioreactor with 4L of culture medium were carried out for 160 hours at 37°C. The agitation speed varied between 300-900rpm in order to maintain pO2 in 5%. To improve the biosurfactant concentration, fed-batch culture was performed witch up to three pulses of glycerol feeding, inceasing the concentration of the medium by up to 30% of initial. The results show that Pseudomonas aeruginosa LBI 2AI was able to produce rhamnolipídios from residual glycerol from Biodiesel production in the strategies used in this study. Bioreactor cultures enabled an increase in the concentration of the product formed, using the treated and untreated Glycerol residues. Promising concentrations of rhamnolipids using these carbon sources were achieved increasing the concentration. ; A utilização do biodiesel como alternativa em ...

Várias Conferencias das Partes (COP) foram realizadas, definindo ações e metas a serem cumpridas pelas nações, que visem valorizar os ecossistemas e a reduzir a extinção de espécies, garantindo a diversidade genética; o uso sustentável da biodiversidade e o reconhecimento real do custo dos serviços ecossistêmicos prestados à sociedade; a repartição de benefícios do uso dos recursos genéticos junto as suas comunidades de origem, incluindo suas sequencias digitais; a disponibilização de recursos financeiros relevantes para garantir a capacitação e a cooperação técnica e científica; e, o acesso a transferência de tecnologia de forma equitativa à todos os países. Todas elas pressupõem o uso de tecnologias e sua disseminação para as populações locais, além de ações no marco do conceito de Bioeconomia. O presente texto procura trazer referências para questões que envolvem os usos dos recursos biológicos, a biodiversidade, e o uso econômico, a bioeconomia, e sugere uma reflexão: se a parceria é legítima, qual o melhor modelo? Abstract: Biodiversity conservation, a subject that was previously distant from the Brazilian society, is addressed in different international forums, led by the United Nations (UN) notably in the Convention on Biological Diversity (CBD). Several Conferences of the Parties (COP) were held and defined actions and goals to be met by nations, which aim to value ecosystems and reduce the extinction of species, guaranteeing genetic diversity; the sustainable use of biodiversity and the real recognition of the cost of ecosystem services provided to society; the sharing of benefits from the use of genetic resources with their communities of origin, including their digital sequences; the provision of relevant financial resources to guarantee training, technical and scientific cooperation; and, equitable access to technology transfer to all countries. All of them require the use of technologies and their dissemination to local populations, in addition to actions within the framework of the bioeconomy concept. This text seeks to bring references to issues involving the use of biological resources, biodiversity, and its economic use, bioeconomy, and suggests a reflection: if the partnership is legitimate, what would be the suitable model?

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Master thesis 2014 BrazilPublisher:Universidade Federal do Rio Grande do Norte Authors: Galvão, Luzia Patrícia Fernandes de Carvalho;The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly due to long periods of storage. Because of this, the oxidation stability has been the focus of numerous researches since it directly affects the producers, distributors and users of fuel. One of the possibilities to increase the resistance of biodiesel is the autoxidation treatment with inhibitors of oxidation. The antioxidants can be used as potential inhibitors of the effects of oxidation on the kinematic viscosity and the index of acidity of biodiesel, thereby increasing oxidative stability. This work aims to examine the efficiency of antioxidants, α-tocopherol and butylated hydroxy-toluene (BHT), added the biodiesel content of remembrance through Pressurized-Differential Scanning Calorimetry (P-DSC), Thermogravimetry (TG) and Petrology. The results showed that the use of antioxidant BHT, at the concentration of 2000ppm, increased resistance to oxidation of the biodiesel and oxidative induction time (OIT), which is a better result as antioxidant than the α-tocopherol. With the thermogravimetric analysis, it was observed that the biodiesel presented an initial decomposition temperature of lower tendency than that of oil, demonstrating to be more volatile, bearing great similarity to the diesel and being characterized as an alternative fuel. The rheological analysis indicated that each sample of biodiesel behaved as a Newtonian fluid ; O biodiesel é definido como o derivado mono-alquil éster de ácidos graxos de cadeia longa, proveniente de fontes renováveis como óleos vegetais ou gordura animal, cuja utilização está associada à substituição de combustíveis fósseis em motores ciclo diesel.

The Third Sector Institutions have acquired an important role on the society through the years, with new demands that have been given to them in financial and human terms. Manny studies were made under the sustainability of PISS (Private Institutions of Social Solidarity). However, this study is going to be focused on Cerebral Palsy PISS’s, where economic and financial problems still persist. Also, this is a very sensible area of the society where resources are scarce due to the lack of economic and financial support. The main objective of this study is to determine which factors may put in cause the sustainability of the PISS’s. Several methods were utilized to determine the statistics of our analysis. Those are, the quantitative method, a series of questionnaires and the analysis of multiple data that was available to us. In this study we also pretend to verify which factors may lead to the loss of sustainability of this Institutions, the risks zones they face, in the area of Cerebral Palsy. These areas are their own indebtedness, the marking of possible areas on where value can be generated, the formulation of possible suggestions, and the prioritization of transformation programs. In general, the factors that have contributed to the economic vulnerability of this PISS’s are according with the respondents, and in the majority of the cases, related with their own management and their economic and financial aspects. Also, with this study, we pretend to innovate, creating guidelines and limiting sustainability risk zones. These guidelines aim to serve in the future, several PISS managers and technicians, with the intent of detecting this referred symptom’s, which may lead these Institutions to an economic default and also to a state of bankruptcy. Due to the fact of these Institutions being highly dependent from Public State economic support, is required from their leader’s several innovative measures, as much in human and technical terms, measures which allow them to be self-sustainable and at the same time permitting these agents to be important in the social intervention, with significant impact on the underprivileged populations. As Instituições do Terceiro Setor têm vindo a adquirir um importante papel na Sociedade ao longo dos tempos, com novas exigências lhe são impostas, tanto em recursos humanos como financeiros. Muitos estudos se têm vindo a realizar no âmbito da Sustentabilidade das IPSS. No entanto, este irá abranger o Setor das IPSS de Paralisia Cerebral, Instituições onde os problemas económico-financeiros são determinantes, e também por ser um uma das áreas mais sensíveis da Sociedade, onde os recursos são escassos. O objetivo principal deste estudo é o de saber quais os fatores que poderão pôr em causa a Sustentabilidade das IPSS de Paralisia Cerebral. Para isso utilizou-se o método quantitativo, através de um questionário por Inquérito e pela análise dos Balanços e das Demonstrações de Resultados, por forma a completar, em termos estatísticos, a nossa análise. Da interpretação desses resultados pretende-se determinar quais os fatores da perda da Sustentabilidade destas IPSS, quais as zonas de risco que enfrentam, nomeadamente o endividamento, identificar as áreas passíveis para a Criação de Valor, formular possíveis recomendações e priorizar iniciativas para a implementação de um programa de transformação. Os fatores que de uma maneira geral que contribuíram para a vulnerabilidade financeira destas IPSS segundo os participantes inquiridos, estão na grande maioria dos casos, relacionados com sintomas relativos com a parte económico-financeira e de gestão. Com este estudo, também se procurou inovar, criando um quadro orientador e limitador das zonas de risco de perda de sustentabilidade, mapa esse que poderá servir no futuro aos gestores e técnicos das IPSS, para detetarem o aparecimento de tais sintomas, os quais podem levar as Instituições a situações de incumprimento e eventualmente a um estado de falência. A situação de subsídio dependência em relação ao Estado, requer por parte dos dirigentes a adoção de novas medidas inovadoras, quer em termos técnicos quer humanos, que lhes permitam serem autossustentáveis, continuando a serem agentes importantes na intervenção social, com impacto significativo junto das populações mais desfavorecidas.

Such preference is justified by landscape and aesthetic's value, as well as the need for recreation and leisure activities of individuals. The tourism industry, aiming profitability, appropriates themselves of such reality by means of a discourse based on sustainability. Such scenario has already reached the State of Sergipe, which has a diversity of splendiferous landscapes and a cultural diversity that express tourist potentialities. Vaza-Barris estuary is engaged in this context, since it has been touristic explored, specifically, after the construction of Orla Pôr do Sol (Sunset Edge) and Joel Silveira's brigde. In this sense, the activities that occur in the estuary, specifically, on Pôr-do- Sol Orla, Ilha da Paz (Island of Peace), and Ilha Paraiso (Paradise Island), are being damaged by touristic activities and these places don't have any kind of management plan, which has been compromising the local sustainability. In this context, this study aimed to analyze the sustainability of tourist's activities developed at the estuary of Vaza-Barris’s River, since these Islands are areas of intense touristic visitation as well as they are considered Permanent Preservation Areas (APP's) but they don't present until now any kind of management plans. As methodology we used exploratory research, documentary and bibliographic, and data collection instruments such as: questionnaires, observation of the study area and semi-structured interviews with the residents of the locality and Public bodies. Reach the conclusion that the systematic examination of the relationship between the General Law of Tourism, public policies for sustainable tourism in Sergipe State and the reality of tourism in the Mosqueiro Village hasn't showed favorable trends for sustainability, being necessary a intervention from the public bodies of tourism and the public bodies of environmental government in order to elaborate a plan for public use of this places as well as it is ...

Não recebi financiamento ; A energia fotovoltaica vem ganhando cada vez mais espaço na matriz energética brasileira. Sendo assim, levantou-se a hipótese de utilizar espaços remanescentes de Universidades Públicas, onde geralmente são deixados de lado por serem uma grande área em desuso, para instalação de uma usina fotovoltaica. Onde o principal foco é a instalação de uma usina de minigeração fotovoltaica distribuída compartilhada. Os campus a serem estudados no decorrer da análise, foram três campus da Universidade Estadual Paulista - UNESP, sendo eles: Itapeva, Ourinhos e Rosana, na qual, suas áreas disponíveis são respectivamente 32,4 mil m², 65,13 mil m² e 37,77 mil m². Nestas áreas apresentadas, é possível instalar usinas de até 6,91MW, 13,86MW e 8,04MW. Ou seja, temos que todos os campus atingiriam uma potência maior de 5MW, na qual seria possível a instalação de uma usina para minigeração e ainda haveria espaço suficiente para ampliação do sistema, ou ainda criação de uma usina híbrida. ; Photovoltaic energy has been gaining more and more space in the Brazilian energy matrix. Therefore, the hypothesis was raised of using remaining spaces of Public Universities, where they are usually left aside because they are a large area in disuse, for the installation of a photovoltaic plant. Where the main focus is the installation of a shared distributed photovoltaic minigeneration plant. The campuses to be studied during the analysis were three campuses of Universidade Estadual Paulista - UNESP, namely: Itapeva, Ourinhos and Rosana, in which their available areas are respectively 32.4 thousand m², 65.13 thousand m² and 37 .77 thousand m². In these areas presented, it is possible to install plants of up to 6.91MW, 13.86MW and 8.04MW. That is, we have that all campuses would reach a power greater than 5MW, in which it would be possible to install a plant for minigeneration and there would still be enough space for expansion of the system, or even the creation of a hybrid plant.
