Aplicação de zinco via sementes e seu efeito na germinação, nutrição e desenvolvimento inicial do sorgo

O objetivo deste trabalho foi avaliar o efeito da aplicação de zinco em sementes de sorgo (Sorghum bicolor (L.) Moench) na nutrição, na germinação e no desenvolvimento inicial das plantas, em casa de vegetação. Utilizou-se delineamento inteiramente casualizado dos tratamentos, em esquema fatorial 2x5, duas cultivares de sorgo (BR 304 e BR 310) e cinco doses de Zn (0, 3,57, 7,14, 14,28 e 28,56 g de Zn por kg de sementes), com três repetições. Foram avaliadas as variáveis de germinação (tempo médio, média diária e a velocidade), e 28 dias depois da semeadura, determinou-se a massa da matéria seca e os teores de Zn na parte aérea e nas raízes. A aplicação de Zn nas sementes de sorgo não afetou o acúmulo de matéria seca da parte aérea, entretanto, diminuiu a germinação e o acúmulo de matéria seca das raízes e da planta inteira. O Zn aplicado nas sementes de sorgo acumulou-se principalmente nas raízes. A cultivar BR 304 apresentou maior absorção de Zn e acúmulo de matéria seca, em relação à cultivar BR 310.

O direito coletivo prestacional à saúde e o poder judiciário: a concretização do art. 196 da Constituição de 1988 pela via jurisdicional

During the ninth century, owing to the process of industrialization, new social conflicts were showed, forcing the Government not to remain inert. The necessity of answer to these new demands requires from the State some actions that assure the new economic, cultural and social rights, able to exceed the formal equality, according to the principles of redistributive equality and well-being. Among the social rights, the right to health is showed up, which is placed at the Universal Declaration of Human Rights and the International Treaty for the Economic, Social and Cultural Rights, as a necessary term to promote the dignity and the free development of the human personality. Under the Constitutional Law, it is clear that the implementation of the right to health, placed at the 6th article of the Brazilian Constitution, demands a government activity, which usually requires a provision of material goods, depending on budgetary resources. The Legislative and Executive Branches have a very important role in compliance with the constitutional regulations about the satisfactory offer of health care services, besides the correct use of the resources at this area. The adoption of public policies is the way of Government action to the planning and realization of this right. Though, some public policies are usually made apart from the social compromises, to the detriment of the basic social rights. The government has a discretionary competence to manage the health services. That is the reason it is necessary the control of the political choices, through the popular control, the extrajudicial control by the Account Courts, or the judicial review. Owed to the constitutionalization of social rights, the constitutional justice has a very relevant role, concerning to the constitutional jurisdiction, in a way the Judiciary Branch assume your position as a player that transforms the society. On the control of the public health policies, there is a cast of official instruments, judicial or not, to the guarantee of the collective right to the public health services, and to allow the citizens to reach the real implementation of the right to health

Resposta de plântulas de arroz cv. brs-soberana à aplicação de zinco via semente

A cultura do arroz constitui um dos principais cereais que apresenta alta resposta à aplicação de zinco, constituindo um dos principais cereais em que isso ocorre. Objetivou-se, no presente trabalho, avaliar a aplicação de zinco em sementes, a partir de duas fontes, sobre a nutrição e o crescimento inicial da cultura do arroz cultivar BRS-Soberana. O delineamento experimental utilizado foi o inteiramente casualizado, em três repetições. Os tratamentos foram cinco doses 1,0; 2,0; 4,0 e 8,0g de Zn por kg de semente, das fontes sulfato e óxido, além da testemunha. Após 30 dias da semeadura, avaliou-se a matéria seca (parte aérea e raiz) e o teor e acúmulo de zinco nas plantas. O sulfato de zinco não diferenciou ao óxido para produção de matéria seca total nas plântulas de arroz, entretanto, proporcionou maior absorção de Zn. A aplicação de zinco na forma de sulfato e óxido, na dose de 8g Zn.kg-1 de semente proporcionou maior produção de matéria seca atingindo teor do nutriente, na parte aérea de 281 e 163 mg.kg-1, respectivamente.

Nitrogênio e potássio em bananeira via fertirrigação e adubação convencional-atributos químicos do solo

Realizou-se um experimento em Pindorama (SP), no qual se avaliaram os efeitos da fertirrigação e da adubação convencional com N e K em alguns atributos químicos de solo sob cultivo com bananeira, durante dois ciclos de produção. Avaliaram-se a disponibilidade e a movimentação de nutrientes (P, K, Ca e Mg) no perfil do solo, bem como outros atributos químicos (matéria orgânica, acidez e saturação por bases), por meio de amostragens realizadas na implantação do experimento e ao final do primeiro e segundo ciclos de produção. Os principais efeitos dos tratamentos foram no pH do solo e no teor de K+ trocável. A adubação, tanto aplicada via fertirrigação como na forma convencional, implicou incrementos na acidez do solo, principalmente até 20 cm de profundidade. Observou-se que o impacto da adubação via fertirrigação no pH do solo foi proporcional à dose. A adubação convencional também causou decréscimo no pH, especialmente na região mais próxima das plantas, refletindo o efeito da aplicação localizada dos fertilizantes. A aplicação de adubo sólido na superfície do solo determinou significativo acúmulo de K nas camadas até 20 cm e na região mais próxima ao pseudocaule das plantas. Os efeitos da adubação via fertirrigação foram mais difusos, visto que os adubos são espalhados numa área de solo maior do que a coberta pela adubação convencional.

Desenvolvimento de um protocolo de comunicação para automação de subestações móveis via satélite

One of the most important decisions to turn a substation automatic and no attended it relates to the communication media between this substation and Operation Center. Generally energy companies uses radio or optic fiber, depending of distances and infrastructure of each situation. This rule applies to common substations. Mobile substations are a particular case, therefore they are conceived for use at provisional situations, emergencies, preventive or corrective maintenance. Thus the telecommunication solution used at common substations are not applied so easily to mobile substations, due absence of infrastructure (media) or difficulty to insert the mobile substation data in existing automation network not long. The ideal media must supply covering in a great geographic area to satisfy presented requirements. The implantation costs of this big infrastructure are expensive, however a existing operator may be used. Two services that fulfill that requirements are satellite and cellular telephony. This work presents a solution for automation of mobile substations through satellite. It was successfully implanted at a brazilian electric energy concessionaire named COSERN. The operation became transparent to operators. Other gotten benefits had been operational security, quality in the supply of electric energy and costs reduction. The project presented is a new solution, designed to substations and general applications where few data should be transmitted, but there is difficulties in relation to the media. Despite the satellite having been used, the same resulted can be gotten using celullar telephony, through Short Messages or packet networks as GPRS or EDGE.

Desenvolvimento de um middleware para comunicação via web services e sua aplicação em sistemas de aquisição de dados industriais

The control of industrial processes has become increasingly complex due to variety of factory devices, quality requirement and market competition. Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network

Conversão do metano via oxicloração em reator de leito fixo utilizando catalisador do tipo CuCl2/SiO2

Supported catalysts of CuCl2 on sílica were used in the methane oxychlorination reaction. The materials were synthesized by the ion exchange technique in a basic solution, using a copper-ammonia complex with 3 and 6 % of nominal copper loading. The materials where characterized by thermogravimetry (TG), X-ray Fluorescence Spectroscopy (XRF), Temperature Programmed Reduction (TPR), Scanning Electron Microscopy with X-ray microanalysis (SEM/EDS), BET specific area and pore distribution. The characterization confirms the presence of copper on the support surface, concluding that the ion exchange technique was adequate in the catalyst synthesis. For the reaction test, an oxychlorination bench scale unit was employed. The tests were carried at 673 and 773 K. The results showed the influence of temperature and catalyst copper content on the oxychlorination of methane reaction

Transient stability analysis of electric energy systems via a fuzzy ART-ARTMAP neural network

This work presents a methodology to analyze transient stability (first oscillation) of electric energy systems, using a neural network based on ART architecture (adaptive resonance theory), named fuzzy ART-ARTMAP neural network for real time applications. The security margin is used as a stability analysis criterion, considering three-phase short circuit faults with a transmission line outage. The neural network operation consists of two fundamental phases: the training and the analysis. The training phase needs a great quantity of processing for the realization, while the analysis phase is effectuated almost without computation effort. This is, therefore the principal purpose to use neural networks for solving complex problems that need fast solutions, as the applications in real time. The ART neural networks have as primordial characteristics the plasticity and the stability, which are essential qualities to the training execution and to an efficient analysis. The fuzzy ART-ARTMAP neural network is proposed seeking a superior performance, in terms of precision and speed, when compared to conventional ARTMAP, and much more when compared to the neural networks that use the training by backpropagation algorithm, which is a benchmark in neural network area.

Structural FRF acquisition via electric impedance measurement applied to damage location

Continuing development of new materials makes systems lighter and stronger permitting more complex systems to provide more functionality and flexibility that demands a more effective evaluation of their structural health. Smart material technology has become an area of increasing interest in this field. The combination of smart materials and artificial neural networks can be used as an excellent tool for pattern recognition, turning their application adequate for monitoring and fault classification of equipment and structures. In order to identify the fault, the neural network must be trained using a set of solutions to its corresponding forward Variational problem. After the training process, the net can successfully solve the inverse variational problem in the context of monitoring and fault detection because of their pattern recognition and interpolation capabilities. The use of structural frequency response function is a fundamental portion of structural dynamic analysis, and it can be extracted from measured electric impedance through the electromechanical interaction of a piezoceramic and a structure. In this paper we use the FRF obtained by a mathematical model (FEM) in order to generate the training data for the neural networks, and the identification of damage can be done by measuring electric impedance, since suitable data normalization correlates FRF and electrical impedance.
