Abstract:
<span>This paper presents the comparison between proportional integral (PI) current controller, proportional resonance and harmonic compensator (PR+HC) current controller and modified PR+HC current controller in the inverter system. Power electronic components like inverter and current controller uses in the system produce unwanted harmonics that affect the quality of distribution power network. In this study, development and simulation of current controller using conventional proportional integral (PI), the selective harmonic compensation scheme (PR+HC), and modified version of the latter are considered so to overcome these harmonics injection. Modification is by adding control parameter randomisation technique to the PR+HC scheme. Results compare the three controllers and proved that with modification to the selective harmonic compensation scheme, the overall current THD can be reduced</span>

Abstract:
<p>The intention of this paper is to identify a suitable controller for closed loop multi converter system for multiple input sources and to improve time response of high-gain-step up-converter. Closed-loop Multi Converter System (MCS) is utilized to regulate load-voltage. This effort recommends suitable-controller for closed-two loop-controlled-SEPIC-REBOOST Converter fed DC motor. The estimation of the yield in open-two loop and closed- two-loop-circuit has been done using MATLAB or Simulink. Closed-two loop-control of Multi Converter System with Propotional+Integral (PI)- Propotional+Integral (PI) and Proportional+Resonant (PR) - Proportional+Resonant (PR) Controllers are investigated and their responses are evaluated in conditions of rise time, peak time, settling time and steady state error. It is seen that current-mode PR-PR controlled MCS gives better time domain response in terms of motor speed. A Prototype of MCS has been fabricated in the laboratory and the experimental-results are authenticated with the simulation-results.</p>

Abstract:
Field-oriented control (FOC) has achieved great success in permanent magnet synchronous motor (PMSM) control. For the PMSM drive, FOC allows the motor torque and flux to be controlled separately, which means the torque and flux are decoupled from each other. Since the torque control is achieved by the speed controller, it can be considered that the speed and the flux of the PMSM are also decoupled from each other and can be controlled separately. In this paper, we propose a PMSM vector control using decoupled speed and flux controllers based on the proportional-resonant (PR) control method. A flux controller is proposed to control the flux of the PMSM and generate the d-axis reference current, whereas the speed regulator is used to generate the torque as well as the q-axis reference current. The PR controller is proposed to control the dq-axis currents and generate the reference voltages; its design is included.Therefore, decoupled speed and flux controllers are controlled separately using the PR controller. The Matlab/Simulink environment is utilized for the simulation, while the dSPACE DS1104 is used for the experimental work. The proposed control method is simple; there are no flux or torque estimators required, so it can avoid the complexity of estimators in the control scheme. The motor is tested under different scenarios, including flux change, speed change, and load torque change. The simulation and hardware results show the effectiveness of the proposed control method in controlling the the speed and the flux of PMSM with fast motor response and good dynamic performance in the different scenarios.

Abstract:
In this paper, a current feedback control scheme is proposed using Proportional Resonant (PR) for a grid-connected converter with an LCL Filter; PR controller with harmonic compensators has high gain at the desired frequencies for decrease harmonic distortion in the alternative voltage or current. Harmonic compensators of PR controller are limited to several low-order harmonics due to the system instability when the compensated frequency is out of system control loop’s bandwidth. The average value of current flow through inductors of LCL filter is feedback to the PR current regulator. Zero D-axis Control (ZDC) is to control the generator side converter to reduce the DC-link ripples, multi-loop harmonic current controllers are applied to regulate the higher-order harmonics by PR regulators. Consequently control strategy with LCL filter is to reduce third-order function to first-order function. By this way large control loop gain can be chosen to obtain control loop for the required harmonic components of the PR controller. The simulation and experimental results have been illustrated to validate the effectiveness of the proposed method in MATLAB Simulink.

Abstract Closed-loop DC Micro-Grid containing sustainable power sources, stockpiling components and burdens are introduced. The regulators for helping the control of mico-grid are numerous in the power-frameworks, yet the most normally utilized one is PI regulator. Aside from PI there are, an entire bundle of independent regulators and hybrid regulators that can serve significantly better compared to PI for microgrid framework relevance’s. Closed-loop DC microgrid framework system with FOPID-FOPID (Fractional-order-Proportional-Integral Derivative controller) and PR—PR (Proportional-Resonant Controller) based DCMG structures are investigated and re-enacted utilizing Simulink in MATLAB and their outcomes are introduced. After re-enactment analyses, some preliminary eventual outcomes of FOPID-FOPID and PR-PR controlled DCMG framework are given to actually look at the sufficiency of the proposed framework.

Abstract:
In grid connected system, unity power factor current injection into the grid is vital. This can be achieved by choosing the right inverter topology, passive filter components, current controllers, and PWM switching scheme. This paper compares the output current harmonics profile between when using the conventional proportional resonant (PR) current controller and when using the modified PR current controller. By applying the latter technique, via experimental validation using TMS320F2812, the THD of the injected grid current in a parallel connected inverters system is improved.

Abstract:
Robust control and flexible operation are the major objectives of islanded microgrid. A microgrid can have different configurations with linear loads and nonlinear loads. The harmonic current caused by nonlinear loads make Proportional Integral (PI) or Proportional Integral Derivative (PID) voltage controller far beyond excellent performance in case of microgrid operating in islanded mode. Additionally, the robustness of the PID closed loop system can not be guaranteed. The voltage control by using Proportional resonant (PR) controller are recommended. Although PR controller has the ability to sinusoidal signals. However, PR controller has a slight deviation of the frequency of selected harmonic component. This paper presents a Sliding Mode Control (SMC) for voltage control of parallel inverters operating in islanded microgrid. This controller can enhance the robustness of control system and reduced-state tracking error. The stability of the closed-system is verified by means of Lyapunov stability criterion. The control structure is based on the inner sliding mode closed-loop and the outer droop control loop. The main aim of this paper is to design inner controllers to enhance the dynamics of the microgrid. The results obtained from the simulation of Matlab.

Abstract:
Abstract The Smart Grid environment gives more benefits for the consumers, whereas the power quality is one of the challenging factors in the smart grid environment. To protect the system equipment and increase the reliability, different filter technologies are used. Even though, consumers’ expectations towards the power quality are not fulfilled. To overcome these drawbacks and enhance the system reliability, a new Custom Power Devices (CPD) are introduced in the system. Among different CPDs, the Dynamic Voltage Restorer (DVR) is one of the voltage compensating devices that is used to improve the power quality during distortions. When the distortions such as voltage swell and sag occur in the distribution system, the control strategy in the DVR plays a significant role. In this article, the DVR performance using Proportional Integral (PI), Proportional Resonant (PR) controllers are analyzed. A robust optimization algorithm called Self Balanced Differential Evolution (SBDE) is used to find the optimal gain values of the controllers in order to reach the target of global minimum error and obtain fast response. Then, a comparative analysis is performed between different controllers and verified that the performance of PR controller is superior than the other controllers. It has been found that the proposed PR controller strategy reduces the Total Harmonic Distortion (THD) values for all types of faults. The proposed SBDE optimized DVR with PR controller reduces the THD value less than 4% under voltage distoration condition. The DVR topology is validated in MATLAB/SIMULINK in order to detect the disturbance and inject the voltage to compensate the load voltage.

Abstract:
A agricultura familiar tem grande relevância quando se apresentam os números de propriedades produtoras de alimentos brasileiros que abastecem o mercado interno. Neste cenário, destaca-se o cultivo de cogumelos que podem servir de complemento de renda a pequenos produtores, em virtude da utilização de pequenos espaços e da boa aceitação mercadológica. O cogumelo A. blazei é um fungo consumido em decorrência de seu valor medicinal e das propriedades fortalecedoras do sistema imunológico. O cultivo desse tipo de fungo possui características específicas de cuidados, como o monitoramento constante da umidade e temperatura, fatores abióticos fundamentais que podem possibilitar o bom desempenho da safra. Diante disso, este trabalho propõe a automação do controle e do monitoramento de temperatura e umidade por meio de sensores e dispositivos microcontrolados, a custo acessível para a agricultura familiar, propiciando a diminuição da mão de obra do agricultor. Utilizou-se a plataforma Arduino para esse fim. O experimento foi realizado em duas fases, manual e automatizada, a fim de comparar os resultados e identificar a produtividade e a melhor forma de cultivo, assim como a umidade ideal para o desenvolvimento da safra na região em que o experimento foi realizado. Os canteiros que em que os sensores de umidade e temperatura foram instalados apresentaram facilidades no manejo da safra. A segunda safra automatizada apresentou produção de 59,86kg, com 4,31kg de cogumelo A. blazei in natura a mais do que a primeira fase manual. O A. blazei apresentou melhor desempenho no canteiro com a umidade próxima aos 80%, com desvio padrão de 1,13. Nesse cenário, constata-se que a região na qual foi realizado o experimento apresenta condições propícias para o cultivo de cogumelo A. blazei. As informações foram encaminhadas via conexão com a Internet para a plataforma web de Internet das Coisas (IoT) Thingsboard, para armazenamento de dados, o que possibilitou identificar, monitorar e acompanhar os aspectos referentes ao crescimento do A. blazei a distância. Conclui o trabalho que a utilização de sensores e microcontroladores facilita a produção, a identificação da melhor umidade para o desenvolvimento do cultivar e reduz os custos com mão de obra.
Family farming has great relevance when presenting the numbers of Brazilian food producing properties that supply the domestic market. In this scenario, we highlight the cultivation of mushrooms that can supplement income for small producers, due to the use of small spaces and good market acceptance. The A. blazei mushroom is a fungus consumed due to its medicinal value and the strengthening properties of the immune system. The cultivation of this type of fungus has specific characteristics of care, such as the constant monitoring of humidity and temperature, fundamental abiotic factors that can enable the good performance of the crop. In view of this, this work proposes the automation of the control and monitoring of temperature and humidity by means of sensors and microcontrollable devices, at affordable cost for the family agriculture, propitiating the reduction of the workmanship of the farmer. The Arduino platform was used for this purpose. The experiment was carried out in two phases, manual and automated, in order to compare the results and identify the productivity and the best form of cultivation, as well as the ideal humidity for the development of the crop in the region where the experiment was carried out. The beds in which the humidity and temperature sensors were installed showed facilities to handle the harvest. The second automated harvest showed a yield of 59.86 kg, with 4.31 kg of A. blazei mushroom in natura more than the first manual phase. The A. blazei presented better performance at the site with humidity close to 80%, with a standard deviation of 1.13. In this scenario, it is verified that the region in which the experiment was performed presents propitious conditions for the cultivation of A. blazei mushroom. The information was sent via Internet connection to the Thingswo Internet Things (IoT) web platform for data storage, which enabled the identification, monitoring and follow-up of the aspects of A. blazei growth at a distance. It concludes the work that the use of sensors and microcontrollers facilitates the production, identification of the best moisture for the development of the cultivar and reduces labor costs.

Resumo: A cidade de Curitiba no começo do século XX passava por mudanças. O aumento da população, o crescimento de seu território e a modernização urbana e arquitetônica representavam, para uma parcela da sociedade curitibana, a sua transformação em um centro urbano de importância no cenário nacional. No entanto, associadas ao imaginário da cidade moderna, estavam as sensações de medo e insegurança, relacionadas especialmente ao outro, ao desconhecido que se esconde entre a multidão e nas sombras e becos das cidades. Entre os grupos que compõe as "classes perigosas", estão as prostitutas. Classificadas como "mulheres públicas", são o alvo de práticas de vigilância e controle empreendidas pelas instituições policiais. O objetivo deste trabalho é investigar uma destas práticas: a implantação, por parte da Polícia Civil do Paraná, dos prontuários de identificação das meretrizes. Iniciado em 1929, o registro perdurou até 1937. Em um primeiro momento, serão analisados o contexto curitibano e o lugar da prostituição nesta sociedade. Este lugar está relacionado a posição da ciência no século XIX, que transformou os indivíduos das "classes perigosas" em objetos de investigação. O pensamento científico, através do seu estatuto de verdade, passa a influenciar práticas de ordem social, inclusive aquelas relativas à segurança pública. Para compreender o desenvolvimento dos métodos de identificação, será necessário analisar a predominância do pensamento científico e seus desdobramentos no que se refere aos comportamentos que escapam à norma. Em um segundo momento, serão analisadas as apropriações e ressignificações do discurso científico em outras esferas do campo social e na configuração de práticas de vigilância do meretrício. Por fim, analisarei os prontuários de identificação enquanto dispositivo do poder, mas também, sob a perspectiva de que constituem para o historiador uma forma de aproximação, mesmo que intermediada, com o grupo do meretrício e o seu cotidiano nas ruas de Curitiba. A análise da documentação se divide em duas etapas, a primeira se dedicando à parte escrita e a segunda à análise dos registros fotográficos disponíveis nos prontuários. Através destes dados será possível analisar as mulheres identificadas enquanto indivíduos ativos no que se refere a sua constituição enquanto sujeitos. Palavras-chave: Prostituição. Relações de poder. Métodos de identificação.
Abstract: The city of Curitiba, in the beginning of the 20th century, underwent several changes. The increasing population, the territorial expansion, urban and architecture modernization represented, for a share of the society, the transformation of the city into an important urban center on the national scene. Nevertheless, associated to the modern city imaginary, laid the feelings of fear and insecurity, especially related to the otherness, to the unknown that hides amongst the crowds, shadows and alleys in the cities. Among the groups that form the "dangerous classes" are the prostitutes. Rank as "public women", they represent the target of vigilance and control practices engaged by the police institutions. The aim of this thesis is to investigate one of these practices: the implantation, issued by the Civil Police of Paraná, of records that identified the prostitutes. Initiated in 1929, the registration endured until 1937. At first, the analysis will focus on the context of the city and the place prostitution occupied in this society. This place is linked to the role of science in the 19th century, that transformed individuals of "dangerous classes" into investigation objects. The scientific thought , through its statements of truth, started to influence practices of social order, including those related to public security. Comprehending the development of identification methods requires the analysis of scientific thought persistency and its effects regarding behaviors that escape the norm. Furthermore, the analysis will focus on the appropriations and resignifications of the scientific speech in other spheres of the social field and the configuration of vigilance practices in prostitution. Finally, this research will analyze the identifying records as a device of power, likewise, under the perspective that these represent for historians an approximation, even if intermediate, with the prostitution group and its routine on the streets of Curitiba. The document analysis has been separated in two parts, the first being dedicated to writing and the second to the analysis of photographic registrations available in the medical records. Through this data, it will be possible to analyze the women that were identified as active individuals regarding its constitution as subjects. Key-words: Prostitution. Power relations. Identifying methods.

Este estudo tem como tema o princípio da universalização do acesso à saúde, na região Fronteira Noroeste do Estado do Rio Grande do Sul (RS). O objetivo é identificar as concepções dos brasileiros e dos estrangeiros quanto ao direito à inserção no sistema de atenção à saúde no Brasil. A partir das propostas de rearticulação mundial do capital e da lógica da formação dos blocos regionais, neste caso específico o MERCOSUL, esta pesquisa discute a interferência das mesmas sobre a cidadania e os direitos sociais em um mundo sem fronteiras, a partir de categorias centrais como: direitos, cidadania e nacionalidade. Resgata e descreve as políticas de proteção social do Brasil e da Argentina e, a partir desta construção, estabelece uma análise comparativa entre o direito à saúde nesses dois países. Aborda as categorias de acessibilidade e determinantes em saúde como fatores condicionantes na procura dos estrangeiros argentinos pelos serviços de saúde no Brasil. Contextualiza o espaço onde é realizado o estudo e apresenta os dados e a análise dos resultados da pesquisa de campo realizada, abordando a situação do direito à saúde na região. O estudo utiliza como marco de referência a saúde como um direito universal, o que implica ultrapassar os usuais limites territoriais de cada uma das nações. Sua abordagem é dialético-crítica e oferece contribuições para o conhecimento dessa realidade no âmbito profissional em si e subsídios aos gestores para os processos decisórios em relação às políticas de saúde para a área fronteiriça. As descobertas da pesquisa apontam para uma significativa movimentação de usuários argentinos nos serviços de saúde brasileiros e distinções entre os sistemas de saúde do Brasil e da Argentina, assentadas no acesso, na qualidade, na atenção integral e gratuidade dos serviços e ações oferecidas à população. O princípio da universalização do acesso à saúde ainda não foi concretizado nesta região, pois o atendimento aos estrangeiros acontece somente em casos de urgência e emergência. A percepção dos usuários brasileiros sobre a inserção dos estrangeiros no Sistema Único de Saúde (SUS) não é unívoca, porém perpassa a lógica de que devem ser atendidos sempre que se fizer necessário; barreiras e restrições ao acesso deste direito foram identificadas. Os usuários brasileiros relacionam o direito à condição de nacionalidade, atrelam a cidadania ao espaço, ao território. Os estrangeiros não percebem sua inserção no SUS como um direito universal, mas seu ingresso está relacionado a fatores como facilidade no acesso devido à proximidade e localização geográfica e à não existência do serviço de saúde equivalente no país e/ou região de origem.

Family farming is configured as an important strategy for sustainable rural development, food production, job creation and community building and productive practices. In this context, the cities of Toledo and Maripá have increased both in fish production and productivity. Toledo is the first state of the producer in the fish farming sector with a production of about 50 million fry and about six million kilos of fish killed in 2015. But the municipality of Maripá in addition to the production there are the productivity. There are 89 fish farmers, who cultivate an area of about 125.0 ha of water surface, with an average yield of 7.0 t/ha, while the state average is about 2.5 t/ha. As such, good management of small rural property is of great importance for both tax requirements as to the knowledge of the results of the activity. Balance sheets, income statements and other reports based on rural accounting tools are of paramount importance for property management. Thus, this thesis analyzed the financial control of the activity of fish farming in family farming in the cities of Toledo and Maripá in the west of Paraná, listing the aspects of family farming, sustainable development and management real estate. Therefore, on the basis of documentary literature interviews, literature and field-directed fish farmers Toledana Aquaculture Association - Atoaqui and the Association of Aquaculture Aquaculture Producers - Aquimap. The results highlighted the low level of education of fish farmers, a greater financial dependence on activity by Maripá fish farmers, lack of effective financial control in the activity, the situation has an impact development of strategies and future investment. Also noteworthy are the weak provision of technical assistance by associations and the highest percentage of issuance of producer tax notes among Maripá fish farmers. As far as the environmental aspects are concerned, most of the properties comply with the legislation in force. In addition, there is no effective treatment of effluent produced by fish farms in both cities. In addition, research has shown the importance that activity on the income of the families surveyed, which contributes to the improvement of the quality of life of these. However, the major challenge in dealing with this same time, with all the daily financial, political and environmental activities and still manage related to rural properties. Thus, it is expected that this research will contribute to future studies, as well as contribute to the development of family farming, which has an important role in the development of cities and the country
A agricultura familiar configura-se como uma importante estratégia para o Desenvolvimento Rural Sustentável, produzindo alimentos, gerando empregos e estimulando práticas associativas e produtivas. Nesse contexto, os municípios de Toledo e Maripá vem se destacando tanto na produção quanto na produtividade piscícola. Toledo é o 1º produtor do Estado no setor da piscicultura com uma produção de aproximadamente 50 milhões de alevinos e cerca de seis milhões de kg de peixes abatidos em 2015. Já o município de Maripá, além da produção, destaca-se pela produtividade. São 89 piscicultores, os quais cultivam uma área de aproximadamente 125,0 ha de lâmina d água, com produtividade média de 7,0 t/ha, enquanto a média do Estado gira em torno de 2,5 t/ha. Nessa capacidade produtiva, uma boa gestão da pequena propriedade rural é de grande importância, tanto para exigências fiscais quanto para o conhecimento dos resultados da atividade. Os balanços patrimoniais, demonstrações de resultados e outros relatórios extraídos da contabilidade rural são ferramentas de extrema importância para a gestão da propriedade. Assim, a presente dissertação analisou o controle financeiro na atividade da piscicultura na agricultura familiar nos municípios de Toledo e Maripá no Oeste do Paraná, elencando aspectos da agricultura familiar, do desenvolvimento sustentável e da gestão da propriedade. Para tanto, baseou-se em pesquisa documental, bibliográfica e de campo, com entrevistas direcionadas aos piscicultores da Associação Toledana de Aquicultura Atoaqui e da Associação dos Aquicultores de Maripá - Aquimap. Os resultados apontaram para a baixa escolaridade dos piscicultores, maior dependência financeira da atividade por parte dos piscicultores de Maripá, falta de um controle financeiro efetivo na atividade, situação está que impacta negativamente em estabelecer estratégias e projetar investimentos futuros. Indicaram, ainda, a baixa prestação de assistência técnica por parte das associações e o maior percentual de emissão de notas fiscais do produtor entre os piscicultores de Maripá. Em relação a aspectos ambientais, a maioria das propriedades atende à legislação vigente. Por outro lado, não existe um efetivo tratamento dos efluentes produzidos pelas pisciculturas em ambos os municípios. Ademais, a pesquisa evidenciou a importância que a atividade tem na renda das famílias pesquisadas, contribuindo com a melhoria da qualidade de vida destas. No entanto o grande desafio este em trabalhar, ao mesmo tempo, com as questões financeiras, políticas e ambientais e ainda lidar com todas as atividades diárias inerentes as propriedades rurais. Assim, espera-se que está pesquisa contribua com estudos futuros, além de colaborar para o desenvolvimento da agricultura familiar, a qual possui um papel relevante no desenvolvimento dos municípios, bem como do país

Abstract:
O presente trabalho procurou analisar a disseminação dos metais pesados na drenagem, oriundos das atividades de uma empresa de mineração de chumbo localizada às margens do ribeirão do Rocha, afluente do rio Ribeira de Iguape, na divisa dos estados do Paraná e São Paulo. Foram realizadas análises para chumbo, cobre e zinco nos sedimentos de fundo (fração<2um) e águas superficiais. Os sedimentos foram submetidos a abertura ácida forte (concentrações Totais) e análise química sequencial, o que juntamente com o levantamento dos principais parâmetros físico-químicos das água, permitiram a precisa identificação dos focos de contaminação da drenagem e as principais associações dos metais pesados com o material particulado(transporte), cujas preferências encontradas foram entre os oxidróxidos de ferro e manganês e os carbonatos. Em todos os pontos amostrados foram ultrapassados os limites toleráveis para os metais pesados em questão nos sedimentos. Realizaram-se também análises para a dosagem de chumbo nos cabelos do escalpo de crianças moradoras das imediações da mineração. Os resultados mostraram que apesar das concentrações encontradas estarem dentro do limite tolerável, pode estar ocorrendo a incorporação do chumbo via ingestão (intestinal) nos indivíduos amostrados.
The purpose of this work is to study the dispersion of heavy metals from lead mining on the Rocha stream tributary of the Ribeira de Iguape river at the border of the States of São Paulo and Paraná. Lead, copper and zinc were determined in the bottom sediments (fraction <2um) and surficial waters. The sediments were analized by strong acid dissolution methods(total concentrations) and sequencial chemical analysis, that together with the study of the main physic-chemical parameters of waters, allows us to identify contamination points within the drainage by means of heavy metals associations with particulate matter(transported); preferential associations were with iron and manganese oxides/hydroxides and carbonates. Every analized sample contained concentrations of the mentioned sedimentary heavy metals corresponding to levels way beyond tolerable limits. Lead determinations were also obtained for the hair of children living in the vicinities of the mining activities. Results should that in spite of the fact that the values were within the tolerable limits there may be a substantiable addition of lead to the living tissues of the sampled individuals by intestinal absorbtion.

Abstract:
Objetivou-se identificar as espécies de formigas cortadeiras (saúvas) na região de Londrina, bem como as principais espécies vegetais utilizadas por elas e adequações nas principais estratégias de controle. Visando a caracterização das espécies de saúvas, foram coletados 10 soldados por ninhos, em áreas do cinturão verde da cidade e na universidade. O registro das espécies vegetais forrageadas foi realizado tanto nas referidas áreas de coletas, como em outras localidades da região de Londrina. Avaliou-se a redução da atividade de forrageamento em ninhos submetidos a diferentes tratamentos: iscas granuladas (á base de sulfluramida e fipronil), termonebulização (óleo diesel e óleo diesel + deltametrina), polvilhamento (pó à base de deltametrina); além da testemunha. No caso do controle com iscas e pó, direcionou-se a dose nos 3 olheiros de forrageamento mais ativos dos ninhos. Os dados foram submetidos ao teste de Scott Knott. Verificou-se que a espécie de saúva na região de Londrina é Atta sexdens, com forrageamento tanto de dicotiledôneas como monocotiledôneas. Os melhores tratamentos para seu controle foram as iscas granuladas à base de fipronil e sulfluramida, cuja dose, distribuída nos 3 olheiros mais ativos, resultou em satisfatória redução da atividade de forrageamento.
The objective was to identify the species of cut ants (saúvas) in the region of Londrina, and the main species used by them and adustments in the main control strategies. Aiming to characterize the species of ants they were collected by 10 soldiers nests in areas of green belt of the city and university. The record of plant species foraged was carried out in both these areas of collections, as in other locations in Londrina region. We evaluated the reduction of foraging activity in nests undergo different treatments: granulated bait (to the base of sulfluramide and fipronil), fogging (diesel oil and diesel + deltamethrin), powdering (deltamethrin-based powder); and the control. The experimental design was completely randomized blocks, with six treatments and four replications. In the case of control with baits and dust, the dose was directed us 3 scouts foraging more active nests. The data were submitted to the Scott Knott test. It was found that the species of ants in the London area is Atta sexdens with foraging both dicots and monocots. The best treatments for their control were pelleted bait based on fipronil and sulfluramide whose dose, distributed in three scouts more active, resulted in satisfactory reduction of foraging activity.

Sprinkler irrigation, an artificial method of water application, supplies the whole or part of water that crops need. It can be used in several crops. Besides, it is easily adapted to different soils and topographies. Irrigation should be carried out according to the right bulk and uniformity, since it is an important factor to be considered when irrigation systems are under evaluation. Most losses are associated to a direct evaporation and wind drift of water. Thus, this study aimed at evaluating daytime and nighttime irrigation of a conventional sprinkler system, using the Christiansen Uniformity Coefficient (CUC) and quality control techniques. It was carried out at Adroaldo Augusto Colombo, a State Agricultural School in Palotina, Paraná. At the irrigation period, four Xcel-wobbler sprinklers were used, with an anti-drift system during day and nighttime. The weather parameters were recorded during the essays with an anemometer and thermo-hygrometer and both were digital and portable. The Christiansen Uniformity Coefficient was correlated with the process capability index ( ), and by Shewhart control charts, it was observed that irrigation was under control over time. In sprinkler irrigation, the best performance of the system was registered during the night period. At last, this trial concluded that in Palotina, PR, from July to September, the best period for sprinkler irrigation was up from four o clock P.M.
Irrigação por aspersão, método artificial de aplicação de água, supre total ou parcialmente as necessidades hídricas das plantas. Pode ser utilizada em várias culturas, além de ser facilmente adaptada a diferentes tipos de solos e topografias. A irrigação deve ser feita em quantidade e uniformidade satisfatórias, pois é um importante fator a ser considerado na avaliação dos sistemas de irrigação. A maioria das perdas está relacionada com a evaporação direta e arraste pelo vento da água aspergida. Assim, o objetivo deste trabalho foi avaliar a irrigação noturna e diurna de um sistema por aspersão convencional, utilizando o Coeficiente de Uniformidade de Christiansen (CUC), bem como técnicas de controle de qualidade. O experimento foi realizado no Colégio Agrícola Estadual Adroaldo Augusto Colombo, em Palotina, PR. Nas irrigações, foram utilizados quatro aspersores Xcel-wobbler, com sistema antideriva nos períodos diurno e noturno. Os parâmetros climáticos foram monitorados durante os ensaios com um anemômetro e um termohigrômetro, ambos digitais e portáteis. O Coeficiente de Uniformidade de Christiansen foi correlacionado com o índice de capacidade do processo ( ) e gráficos de controle de Shewhart. Foi possível observar que a irrigação esteve sob controle ao longo do tempo e o melhor desempenho do sistema ocorreu no período noturno. No período entre julho e setembro, o horário a partir das 16 horas mostrou-se como o mais indicado para realizar irrigações por aspersão na localidade de Palotina-PR.

Abstract:
This chapter examines how the PRI’s candidate selection and recruitment changed from the hegemonic to the democratic era to capture how electoral competition strengthened the governors at the expense the corporatist sectors and other PRI groups. Under hegemony, the president controlled (through choosing or vetoing) which PRI politician appeared on the ballot, and thus could punish or benefit ambitious politicians within the wide-flung coalition. Once competition grew, however, a candidate’s popularity with voters began to weigh on these decisions and governors began to demand control over nominations for subnational and federal posts. Regime leaders had to devolve power over federal candidacies to state executives because of their ability to win votes for the party, decentralizing the party. National party leaders won a good deal of control over the closed-list PR seats for both the Chamber and the Senate. Most party-affiliated unions lost nomination power because they were unable to choose popular candidates or procure electoral victories, weakening their position within the party.

Abstract:
AbstractUnresectable locally recurrent breast cancers (LRBCs) lead to life-threatening situations and a tremendous loss of quality of life. Most patients have received radiotherapy (RT) during primary treatment and re-irradiation (re-RT) using standard doses might be denied due to the risk of unacceptable cumulative toxicity. Therefore, an effective tumor control is often abandoned.Mild hyperthermia (39–43 °C), allows for significant reductions in re-RT dose and effective tumor responses with acceptable toxicity even after heavy pretreatment. More than 280 patients have been treated with superficial hyperthermia by water-filtered infrared A (wIRA-HT), which can cover even large lesions. Hyperthermia was immediately followed by hypofractionated re-RT of 5x4 Gy, once a week.Evaluating 201 patients, overall response rate was 94%. 170 patients with macroscopic LRBC were stratified into 4 size classes (rClasses), and detailed response rates are presented. Accordingly, response rates of 31 patients with microscopic disease after resection of LRBC are communicated.RT-related acute and late toxicity was limited to grades 1 and 2. Due to this low toxicity, re-recurrences after CR and new local progression after PR could be re-treated using the same treatment schedule. Real-time thermographic and visual controls have allowed to almost exclude the risk of thermal skin damage.

Abstract:
There is a need for refining data security and privacy protection in virtual reality systems which are interactive, creative and dynamic, i.e. where at run-time mutually interactive objects can be added or removed in different contexts while their behavior can be modified. In virtual worlds of this kind, operations on particular objects either should or shouldn’t be allowed to users playing different roles with respect to inter-object interactions. In the VR-PR method presented in this chapter, where VR-PR stands for “Virtual Reality–Privilege Representation”, privileges are represented by pairs, each comprising an object and a meta-operation. Meta-operations are induced automatically from possible object interactions, i.e. generated using automatic analysis of the object method call graphs. Meta-operations reflect the method call scope admitted and are used in the process of creating and modifying privileges, which in turn is controlled by a validation mechanism. Expressive and flexible, privileges based on meta-operations are consistent with a set of objects composing a virtual world, as well as with the interactions between those objects, both interactions and objects permanently evolving. In this chapter it is shown in a series of use cases how the VR-PR approach can be applied to various types of object-oriented virtual worlds. The examples are followed by a broader discussion of the privilege lifecycle in the same virtual environment.
