Identidade e participação da comunidade rural nos processos de desenvolvimento local:desafios e competências do regulado de Nhambita-Moçambique

This thesis is defined as a reflection on the mechanisms of expression and insertion of the homo situs in the participatory governance in Mozambique. For a better understanding of this social fact, it was settled a periodization which covered the decline of colonialism at the time of the independence, which was proclaimed in June 1975, the civil war that lasted over 16 years and the period of the democratic State, further established. Therefore, we sought to understand the mechanisms and failures of the participation of the homo situs in local development projects that absorbed the needs and problems of these peasants, not mobilizing the skills and social competences of these communities. It would be essential for the homo situs a genuine democratic practice involving a political culture based on the social construction of the territories of the traditional man which was characterized by being procedural and historical, finding in participation its higher base. In this context, it would be desirable that the community development in Mozambique could contemplate and respect the choices of the homo situs. For this purpose, it would be fundamental the consistency between theory and practice, which builds and rebuilds, continually the competence of the peasants, facilitating the possibility of realization of their primordial aspirations. In the research, it became apparent that there is not a continuous process of participation of the rural communities, which appear as participants, only at the time of the implementation of the activities. Therefore, even having the participation of the communities expected by the law, with predictable moments of discussion and necessary conditions for that, the State failed to establish an ongoing process of democratic dialogue with traditional populations, as well as it failed to organize, properly, accurate informational bases to help solve the problems of rural areas. These facts have led to obstacles to the process of conquest of the human and civil rights of the traditional communities

Desenvolvimento de um ressoador retangular de fenda com múltiplas camadas de substrato e com utilização de material PBG para sistema de comunicação sem fio

In the globalized world modern telecommunications have assumed key role within the company, causing a large increase in demand for the wireless technology of communication, which has been happening in recent years have greatly increased the number of applications using this technology. Due to this demand, new materials are developed to enable new control mechanisms and propagation of electromagnetic waves. The research to develop new technologies for wireless communication presents a multidisciplinary study that covers from the new geometries for passive antennas, active up to the development of materials for devices that improve the performance at the frequency range of operation. Recently, planar antennas have attracted interest due to their characteristics and advantages when compared with other types of antennas. In the area of mobile communications the need for antennas of this type has become increasingly used, due to intensive development, which needs to operate in multifrequency antennas and broadband. The microstrip antennas have narrow bandwidth due to the dielectric losses generated by irradiation. Another limitation is the degradation of the radiation pattern due to the generation of surface waves in the substrate. Some techniques have been developed to minimize this limitation of bandwidth, such as the study of type materials PBG - Photonic Band Gap, to form the dielectric material. This work has as main objective the development project of a slot resonator with multiple layers and use the type PBG substrate, which carried out the optimization from the numerical analysis and then designed the device initially proposed for the band electromagnetic spectrum between 3-9 GHz, which basically includes the band S to X. Was used as the dielectric material RT/Duroid 5870 and RT/Duroid 6010.LM where both are laminated ceramic-filled PTFE dielectric constants 2.33 and 10.2, respectively. Through an experimental investigation was conducted an analysis of the simulated versus measured by observing the behavior of the radiation characteristics from the height variation of the dielectric multilayer substrates. We also used the LTT method resonators structures rectangular slot with multiple layers of material photonic PBG in order to obtain the resonance frequency and the entire theory involving the electromagnetic parameters of the structure under consideration. xviii The analysis developed in this work was performed using the method LTT - Transverse Transmission Line, in the field of Fourier transform that uses a component propagating in the y direction (transverse to the real direction of propagation z), thus treating the general equations of the fields electric and magnetic and function. The PBG theory is applied to obtain the relative permittivity of the polarizations for the sep photonic composite substrates material. The results are obtained with the commercial software Ansoft HFSS, used for accurate analysis of the electromagnetic behavior of the planar device under study through the Finite Element Method (FEM). Numerical computational results are presented in graphical form in two and three dimensions, playing in the parameters of return loss, frequency of radiation and radiation diagram, radiation efficiency and surface current for the device under study, and have as substrates, photonic materials and had been simulated in an appropriate computational tool. With respect to the planar device design study are presented in the simulated and measured results that show good agreement with measurements made. These results are mainly in the identification of resonance modes and determining the characteristics of the designed device, such as resonant frequency, return loss and radiation pattern

Desenvolvimento de um software de comunicação sem fio aplicado à instrumentação de unidade de elevação de petróleo tipo Plunger Lift

This dissertation aims to develop a software applied to a communication system for a wireless sensor network (WSN) for tracking analog and digital variables and control valve of the gas flow in artificial oil s elevation units, Plunger Lift type. The reason for this implementation is due to the fact that, in the studied plant configuration, the sensors communicate with the PLC (Programmable and Logic Controller) by the cables and pipelines, making any changes in that system, such as changing the layout of it, as well as inconveniences that arise from the nature of the site, such as the vicinity s animals presence that tend to destroy the cables for interconnection of sensors to the PLC. For software development, was used communication polling method via SMAC protocol (Simple Medium Access ControlIEEE 802.15.4 standard) in the CodeWarrior environment to which generated a firmware, loaded into the WSN s transceivers, present in the kit MC13193-EVK, (all items described above are owners of Freescale Semiconductors Inc.). The network monitoring and parameterization used in its application, was developed in LabVIEW software from National Instruments. The results were obtained through the observation of the network s behavior of sensors proposal, focusing on aspects such as: indoor and outdoor quantity of packages received and lost, general aspects of reliability in data transmission, coexistence with other types of wireless networks and power consumption under different operating conditions. The results were considered satisfactory, which showed the software efficiency in this communication system

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

O Desenvolvimento local sustentável no semi-árido nordestino: um estudo de caso na comunidade de mirandas, Caraúbas/RN

Brazil s semi-arid region is an immense territory characterized by a mosaic of natural environments and human settlements. Inside this multifaceted framework, there are problems that are specific to the region (the water resources situation, for example) while others are more universal (such as the inequality between men and women). The circumstances that give rise to these problems are complex and require a holistic view so that our understanding can go beyond the simple concept that this is a problem region . The semi-arid must be perceived as a viable area in need of a new analysis, taking into account its successes, limitations, challenges and the strategic public policy framework that guarantees its sustainable development. The dissertation analyzes, from a sustainable local development perspective, the experience of the Northeastern Brazil Groundwater Project (PROASNE), carried out from 2001 to 2003, in partnership with the Waters and Sewers Company of Rio Grande do Norte (CAERN) in the rural community of Mirandas, municipality of Caraúbas/RN, situated in the middle of the northeastern Brazil semi-arid region

Quilombolas e desenvolvimento sustentável: análise a partir da comunidade Capoeira dos Negros (Macaíba/RN)

Quilombo communities remaining are groups marked by insufficient public assistance and characterized by living in rural and conducting economic activities such as agriculture. The development on a sustainable basis is important to ensure strategies for economic growth and environmental preservation. This work aims to study the remaining Quilombo Capoeira Black community, located in the municipality of Macaíba, Rio Grande do Norte, considering the principles of sustainable development. Attempt to respond to what level such community can be considered sustainable from an analysis of their social practices. The methodological procedures used consisted of a literature review and documentary, questionnaires, conducting semi-structured interviews and direct observation. The final results show that the family farm has characteristics that approximate the principles of sustainable development, including the diversification of labor, food production with less environmental damage and strengthening the rural environment, and indicate that the main economic activities practiced in Capoeira dos Negros community are agriculture, manufacturing of cassava flour and brick manufacturing, which, in turn, are linked to negative environmental impacts, such as sedimentation pond, groundwater contamination, air pollution and soil erosion. What lead to the conclusion that the social practices of the community are not in line with the dimensions of sustainable development. It is hoped that the survey results provide subsidies for development and implementation of public policies

A comunicação interna numa organização pública

The present study compose an analysis on the process of internal communication at a public organization, built on the survey data originary of administrative conduct, observation on the cultural model of the organization and how the interdepartmental and interpersonal relations shows up. The research, exploratory descriptive kind, had theoretical basis on two knowledge areas Administrative Science and Social Communication and was developed at Instituto do Desenvolvimento Econômico e Meio Ambiente IDEMA, in Rio Grande do Norte. During data collection, were conducted spontaneous and semi structured interviews with directors and coordinators, besides the application of directed questionnaire to functionaries in two unites of the institution. Through the analysis and interpretation of the data, we came to the conclusion that the process of internal communication at a public organization fall in with same challenges of private organizations, but with peculiarities that attracts the scientific look specially, in concern of the attitude assumed by the administrators in the conduction of communication functions inside the organization, the profile of social actor and the communication channels used. Although the organizational communication represents more and more a strategic function, as an administration tool, the point that research gets to shows that in public organizations the communication refrains from administrative purpose and with the major objective of giving publicity to the institutional acts and actions

Avaliação da qualidade da água do Rio Piranhas-Açu/RN utilizando a comunidade de macroinvertebrados bentônicos

The biomonitoring technique for water quality in water bodies has been incorporated increasingly in management of the natural resources, using mainly indices of its aquatic community characteristics. In Brazil the first efforts to use this technique was restricted to the South and the Midwest region of this country. Located in the northeast region, this study was conducted at Rio Grande do Norte state and had as main objective the assessment of water quality in the Piranhas-Açu river using benthic macroinvertebrates community as biological indicators. Thus, were applied two biotic indices, the BMWP (Biological Monitoring Working Party score system) and the IBF (Family Biotic Index). According the requirements of these indices, two periods of sampling were determined as basic methodology, in dry seasons of 2006 and 2007. The sampling sites were around the municipalities of Açu, Ipanguaçu, Alto do Rodrigues and Pendências. Physical-chemical measurements; a protocol of rapid assessment of diversity of habitats, and determination of the degree of tolerance of each taxon to organic pollution were also performed. The most abundant organisms found in the river were tolerant with the prevalence of Chironomidae (Diptera) and Melanoides tuberculata. This results, together with those ones got in indices application, showed a considerable organic pollution in the four sample places and the reaches were classified as modified to impacted. According to the used indices, this study suggest that this river have significant alteration in the biotic community and water quality on the organic pollution, and this fact, occurs in the reach of the river further downstream, where were expected a good water quality. Considering these results, measures aiming the conservation of this water body are needed regarding as it is inserted into a fragile ecosystem with dry season phenomenon, and the water of this river has extremely importance for the local economy
