Simulação do sistema de esgotamento sanitário de Ponta Negra- Natal: mitigação dos riscos ambientais e estratégia de manutenção preditiva

The simulation of SES-Natal Ponta Negra: mitigation of environmental risks and predictive maintenance strategy was developed in the context of several operational irregularities in the pumping stations and sewage systems in the system Ponta Negra. Thus, the environmental risks and complaints against the company due to overflows of sewage into the public thoroughfare became common. This neighborhood has shown in recent years an increase of resident higher than the initial expectation of growth. In this sense presumed the large population growth and generation of sewers higher than expected, associated to the use of corrective maintenance and misuse of the system may be the main causes of operational failures occurring in the SES. This study aimed at analyzing the hydraulic behavior of SES Ponta Negrathrough numerical simulation of its operation associated to future scenarios of occupation. The SES Ponta Negra has a long lengthof collection networks and 6 pumping stations interconnected, being EE 1, 2, 4 coastal way, and beach Shopping interconnected EE3 to receives all sewers pumped from the rest pumping station and pumped to the sewage treatment station of neighborhood which consists of a facultative pond followed by three maturation ponds with disposal of treated effluent into infiltration ditches. Oncethey are connected with each other, the study was conducted considering the days and times of higher inflow for all lifts. Furthermore, with the aim of measuring the gatherer network failures were conducted data survey of on the networks. Thephysical and operational survey data was conducted between January/2011 and janeiro/2012. The simulation of the SES was developed with the aim ofdemonstrating its functioning, eithercurrently and in the coming years, based in population estimates and sewage flow. The collected data represents the current framework of the pumping stations of the SES Ponta Negra and served as input to the model developed in MS Excel ® spreadsheet which allowed simulating the behavior of SES in future scenarios. The results of this study show thatBeach Shopping Pumping Station is actually undersized and presents serious functioning problemsthatmay compromise the environmental quality of surrounding area. The other pumping stations of the system will reach itsmaximum capacity between 2013 and 2015, although the EE1 and EE3 demonstrateoperation capacity, even precariously, until 2017. Moreover, it was observed that the misuse of the network system, due to the input of both garbage and stormwater, are major factors of failures that occur in the SES. Finally, it was found that the corrective maintenance appliance, rather than predictive,has proven to beinefficient because of the serious failuresin the system, causing damage to the environment and health risks to users

Avaliação da flotação por ar dissolvido no polimento de efluentes de lagoa de estabilização

Experience in the use of stabilization ponds shows that this is a system with low cost, easy operation and maintenance and suitable for tropical countries. One of its disadvantages is due to high concentrations of suspended solids, mainly due to algal biomass in the effluents. Accordingly, the dissolved air flotation has been shown to be an efficient post-treatment technology. However, the efficiency of this process is related to coagulation and flocculation steps, as well as the adjustment of the involved variables in the process. The objective of this work was to evaluate the algae removal efficiency from wastewater stabilization ponds and the influence of the factors involved in the process using dissolved air flotation. For this, we used primary facultative and maturation effluents of ETE Ponta Negra in Natal. We did tests of coagulation, flocculation and flotation with the samples, using the equipment flotatest. In this process were tested coagulants aluminum sulfate and ferric chloride, and varied the factors pH, coagulant concentration, polymer concentration and rate of recirculation. At the end of the experiments were analyzed turbidity, suspended solids, color, COD and chlorophyll "a". These results were submitted to descriptive statistics to verify the efficiency of the process in general, and regression analysis to identify models that describe the process and demonstrate the factors that have greater influence on flotation. After step methodology, high values were found removal efficiency of suspended solids, reaching values greater than 90% in the best cases. It was concluded that flotation is more efficient in the facultative pond effluent using ferric chloride, and the variability of algae may negatively influence the process. Regression analyzes showed that pH is the most influential variable in the coagulation-flocculation-flotation, and its optimal value among the tested is 5.5 for both coagulants

Natureza de mulher, nome de mãe, marca de negra: identidades em trânsito e políticas do corpo na comunidade quilombola de Boa Vista dos Negros

Las políticas de salud destinadas a las mulheres de la comunidad quilombola de Boa Vista son, de manera general, las mismas políticas destinadas al resto de las mujeres de la región rural del Seridó norterriograndense y también las que se corresponden con regiones marginales del Brasil entero. Aquí, el cuerpo femenino es concebido bajo parámetros universalizantes que lo toman como una entidad homogénea y comparable con otros cuerpos femeninos a partir de su traducción en índices, tasas y estadísticas. En este sentido, decimos que son cuerpos desnudos, cuya intervención no considera los rasgos exteriores, aquellos llamados de culturales, como marcadores de identidad. Por otro lado, la noción de Salud de la Mujer Negra propuesta por recientes políticas de Estado a nivel nacional, se muestra inexistente en la comunidad. El cuerpo que se se exalta hoy a partir de los parámetros de reivindicación étnica es un cuerpo negro, pero también bello, jovem e sobre todo, fuerte; donde la noción de salud no penetra. De esta forma, las dos políticas conciben sujetos sociales diferentes. Sin embargo, existe otro espacio, que es el espacio de las prácticas vernáculas, en el que las mujeres experimentan la articulación entre feminilidad y negritud, pero a partir de otros parámetros local e históricamente delineados. Aquí, tanto las trayectorias de las mujeres como las redes de parentesco y cuidado locales se muestran especialmente significativas, ayudando a comprender las concepciones particulares sobre el cuerpo que imaginan y practican las mujeres de esta comunidad, y revelando la importancia de la maternidad como principio ordenador de identidades sociales. Para eso, hemos realizado un trabajo de observación participante, una serie de 30 entrevista com mujeres de Boa Vista y un estudio de las redes de parentesco organizadas alrededor del término mãe. Con esto, demostramos que existe un espacio cargado de significados sobre el cuerpo femenino y la feminilidad que es construido a partir de una interpretación local de la triple condición de mulher, de mãe y de negra

Influência das áreas verdes no microclima local: um estudo do conjunto habitacional Ponta Negra, Natal/RN

Owing to na intense process of urban development, urban uneasiness and discomfort in the daily life of populations have nowadays, especially in the big cities, become increasingly ordinary issues. Population density, degeneration of central areas and pollution are some of the environmental stressors the urban man is subjected to. The existence of open areas in the urban network contributes to a better movement of the air and transforms salubrity conditions. Yet, it has been noticed that parks and squares are disappearing from the heart of the city districts. In their place there are either unused plots of land where garbage has been dumped or nearly all-paved squares with meager or no vegetation at all. Such areas, when handled properly, play an important role in the city because in addition to being zones for rendering a mild climate they perform social, cultural and hygienic functions. Aiming at demonstrating that proper handling of green areas can favorably influence the local microclimate, we have attempted to develop analysis from the point of view of bioclimatizing attributes of urban form and their relationship to the local microclimate found in the eight open areas located in the Ponta Negra Housing Complex in the city of Natal/RN

Configurando a cidade contemporânea em Natal : os processos espaciais em Ponta Negra

This dissertation is about the spatial configuration in Natal and processes in the Ponta Negra neighborhood today. Ponta Negra has undergone a number of critical social and spatial changes due to tourism development after the 1990s. It is of special interest to consider the intensification of real estate investment after 2000, when the new airport terminal, located in the neighboring municipality of Parnamirim, was in use. Ponta Negra is the place where most tourists go to, so attracting considerable public investments. New agents of transformation have produced change in the neighborhood as well. The present study aims at analysing the spatial processes in this part of the city. Here, the spatial configuration that resulted from extended real estate investments, both public and private, in recent years, is analysed in detail. The study identifies the multually differentiated, however internally homogenous areas. The concepts of production of space, contemporanean urban development and spatial dynamics are discussed. The research is based on document analysis and field work. Results were plotted to maps and tables. A detailed analysis of the spatial processes in the Ponta Negra neighborhood is undertaken as a conclusion, considering the contemporanean global scenario

De gata borralheira a Cinderela :nova espacialidade decorrente do desenvolvimento turístico, diferenciada pelo estilo de vida em Ponta Negra, Natal, RN

The transformations economical, social and politics in you finish them decades of the century XX brought changes that didn't just limit to the production system. The flexible accumulation took many workers lost her/it their workstations and they look for her/it new survival forms, migrating for administrative activities, of services rendered and for the tourist activity of small and medium load. The State has been investing in the implantation of plans of tourist development in order to create favorable conditions for the reproduction of the tourist activity in Brazil, mainly in the Northeast. A space when it starts to present a predominant economical activity suffers a restructuring in their social and economical relationships. The restructuring of these relationships takes to the construction of a new espacialidade. In the city of Christmas, in Rio Grande do Norte, the neighborhood of Black Tip is the most representative of the public investments for the tourist development. After intense process of tourist urbanization, Black Tip passed interfering in the global context consolidating as the tourist locus in the city. The tourist urbanization of the neighborhood took to the transformation of the space in merchandise that is sold and consumed as such. The recreation of fragments of other cultures brought by social actors, resulting from migratory processes stimulated by the tourist development, it has been presenting ruled social relationships in the informational technology, consumption of global goods and in the fragmentation of the urban space characterized by the internationalization and cosmopolitização. That process has been masking the inequalities partners and cultural as well as the territorial appropriation for an economical elite. The spaces are being appropriate for investors of the tourist section, private investors, agents and real estate producers, where the inequality is not just economical, but also cultural. The local population, mainly of the urban fraction of the Town of Black Tip, it doesn't participate of the productive process in function of the little or any professional qualification and he/she doesn't also have access to the consumption process. To the native ones it remains the fight for the preservation of his/her cultural identity and for the survival

Análise dos efeitos da legislação urbanística na formação e crescimento do Bairro de Lagoa Nova: planos diretores de 1974, 1984 e 1994

To Analyze the Managing Plans of Natal in the decades of 1970, 1980 and 1990, identifying elements that had contributed for the growth of the Lagoa Nova quarter, capital one of the Rio Grande do Norte state. Ahead of the sped up growth of the urban centers, many times is not given to analyze which law had taken care of to its objective, and which the imperfections that had appeared during the application of these laws. To make the comparisons in you square them chosen at there distantinct times made possible to analyze the form as the ground of Lagoa Nova absorbed the proposals laws.Therefore toanalyze influences it of the Managing Plans, to make comparatives analyses between the urbanistics condicion, made possible to understand that the fabric urban of the quarter of Lagoa Nova is a true granary of information that it makes possible to the dedicated ones to the urban studies, a true field of analysis

Ecologia alimentar e reprodutiva da piaba-do-rabo-amarelo, Astyanax cf. lacustris (Reinhardt, 1874) (Osteichthyes: Characidae) na Lagoa do Piató, Assu, Rio Grande do Norte, Brasil

The feeding habits and biological aspects of the reproductive cycle of two-spot astyanax, Astyanax cf. lacustris (Reinhardt, 1874) were investigated. Fish samples were captured on a monthly basis, using gillnets of 4 cm mesh size, from the Piató Lake, Assu, Rio Grande do Norte, during the period of September, 2006 to August, 2007. Physico-chemical parameters, such as, temperature, electrical conductivity and dissolved oxygen of the lake were registered. The monthly values of rainfall also were obtained. The 360 individuals captured, were measured, weighed, dissected, and stomach weight and the stage of gonadal maturity were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion with limnological parameters and rainfall. The food items identified were separated into distinct groups according to their origin. Sex ratio and Gonadosomatic Relation of females were verified to determine the spawning period and fecundity. The physico-chemical parameters presented the following annual mean values: temperature = 28.8ºC, electrical conductivity = 992.5 µS.cm-1; dissolved oxygen = 4.9 mg.L-1 during the study period. The annual mean of the rainfall was 63.5 mm. The results indicate that this species present an omnivorous feeding habit with a tendency towards insectivory, with an increase in feeding activity during the dry season. The aquatic oxygen to interfere very importance in the feeding activity than the others factors physico-chemicals of water and rainfall. There was a predominance of females, with a sex proportion of 1M:7F. The macroscopic characteristics of the ovaries and testicles revealed four stages of gonadal development: immature, maturing, mature and spent. A temporal variation was observed for the gonadal development of males and females. There was reproductive activity through out the year, with peaks in the months of February, April and June to correspond with the rain of precipitation of the region. The mean fecundity was 7.681 mature oocytes, varying from 4.476 to 12.036, with mean of 7.681. There was positive relation between fecundity and body mass. Condition Factor is not an efficient indicator of the reproductive period of this species. The species A. cf. lacustris is an opportunist and is well adapted to the conditions of the semi-arid Caatinga Biome

Comunidade fitoplanctônica e qualidade da água da lagoa do jiqui, parnamirim, rn

It is important to evaluate the quality of water for proper management of these resources, since the increase of environmental degradation and the multiple use of water resources are decreasing the quality of water consumed by living beings. The objective of this study was to characterize the phytoplankton community and its variations during periods of dray and rain in Jiqui Lake located in Parnamirim, RN. It was also aimed to analyze the physical and chemical factors of this environment, in order to contribute to the knowledge of water quality used for human consumption. The collection of water samples were carried out in September 2008 to August 2009. The collection of the phytoplankton community was carried out in four sampling sites (surface, bottom, margin of the lake without macrophytes and site dominated by macrophytes). Phytoplankton was collected using plankton net of 20m. The analysis of nutrients and identification of phytoplankton were performed in the laboratory. The results indicate that concentration of chlorophyll a was high in the bottom with mean value of 1.07 μgL-1 (SD ± 1.61). During the study period there was a dominance of the following species: Euglena gracilis, Trachelomonas sp, Cyclotellas sp, Gomphonema apuncto, Navicula cuspidata var. cuspidata, Navicula sp, Rhopalodia gibba. There was homogeneity between limnological values in the four study sites, with significant difference between the periods of drought and rain. The Jiqui Lake is considered oligotrophic due to its low concentrations of chlorophyll a, high transparency and low levels of nutrients. The values of BOD and chlorophyll a concentration remained below the permitted standards existing for freshwaters in Brazil, thus the water from Lake Jiqui is of good quality, suitable for human consumption.

Um lugar que passa e sobrevive:o passado e o presente na Vila de Ponta Negra

The Ponta Negra borough is a part and the originally core of Ponta Negra quarter, placed on the South area of Natal/RN city. Its population was constituted by fishermen whose, beyond the fishing work, cultivated small plantations, made carbon and lace. For a long period of time, the borough was isolated from the rest of the city because of the great ground distance and due the fact that the local inhabitants found their own maintenance on the place. The scenery was being little by little modified from de 80 s because of the neighborhood urban development, that became one of the most searching tourism places in the city that turns the borough into a expensive place to live, with plenty of entertainment and high income, due the new habitation standards, new economic activities, new inhabitants belonging to higher social classes, new habits and way of living. The present work aims to verify weather or not, in the middle of all changes, the original social actors that still live in the Ponta Negra borough, are able to keep the traditional community bounds that once guided their existences. On that sense, we will analyze the conflicts that pass through the community, with attention on the sociability, space usage and appropriation

Programa alfabetização solidária: um estudo sobre a experiência no município de Lagoa de Pedras/RN (1997 - 2003)

The educational reform of the 90 s was tainted by the objectives of the fiscal adjustments, resulting in the redefinition of the state s role in the financing and offering of teaching services, and bringing about a shuffling of the responsibility between the public and private sectors to promote education to young people and adults. The 90 s also highlighted the proliferation of providers and the multiplication of Educational Programs for Youths and Adults (EJA), implemented through partnerships between governmental and nongovernmental agencies. During this period of time, the agenda of educational responsibilities concerning analphabetism was organized in a process of decentralized of the state, with the following political, social, and economic objectives: to reduce the public deficit, increasing public savings and the financial capacity of the state to concentrate resources in areas considered indispensable to direct intervention; to increase the efficiency of the social services moffered or funded by the state, giving citizens more at a lower cost, and spreading services to more remote areas, expanding access to reach those most in need; to increase the participation of citizens in public management, stimulating communitarian acts as well as developing efforts towards the effective coordination of public figures in the implementation of associated social services. Thus, Assistance Programs co-financed by the government try to deal with the problem of analphabetism. Within the sphere of the 90 s educational policy decentralization, we come to see how the agenda dedicated to the reduction of analphabetism was formed by the Solidarity Alphabetization Program (PAS). Between 1997 and 2003, the latter agenda s decentralizing proposal was integrated in the management partnership for the operationalization of tasks and resources faced with the execution of the formal objectives. In this study, we identify the dimensions of the implantation and progress of the tasks carried out by PAS, in the municipality of Lagoa de Pedras/RN. However, we consider these Programs to assist in the process without guaranteeing the reduction of the causes or substituting the responsibility of the system once the monetary resources for program maintenance provided by the partners is exhausted

A luta do Bispo Dom José de Medeiros Delgado por educação escolar para todos (Caicó-RN, 1941-1951)

The socioeducational program of actions developed by Dom José de Medeiros Delgado, first Bishop of Diocese of Caicó city in Rio Grande do Norte, from 1941 to 1951, is analyzed by the present work in a historical perspective, based upon the school culture refecence.Through this reference point, the general and peculiar school culture proper of catholic schools founded by Dom Delgado was learned.The schools are: the Ginásio Diocesano Seridoense (1942), the Escola Doméstica Popular Darci Vargas (1943, the Prevocacional School of Caicó (1944) and the Santo Cura d ars Seminar (1946). The socioeducational actions of Dom Delgado Bishop affected seven other towns surrounding Caicó. Places where catholic schools were founded and named after Escola do Pobre . In fight for schools for all social segments of city and rural natures, Dom Delgado founded four rural schools in the surroundings of Serra Negra, São João do Sabugi, Jardim do Seridó e Lagoa Nova. It is also part of his beneficial work the creation of rural cooperatives for the parents of the students from such schools

Lagoa do Piató: a educação como uma obra de arte

A partir de una concepción de la educación como una obra de arte, la disertación revela los estudios realizados en una escuela de la comunidad de Areia Branca Piató, en la Laguna de Piató en Assú, Estado de Rio Grande do Norte. Como una forma de hacer dialogar conocimientos científicos y saberes tradicionales, la investigación establece el intercambio de saberes y afectos sobre todo por intermedio del intelectual de la tradición Francisco Lucas da Silva. Para construir un conocimiento pertinente (Edgar Morin), el que forma parte de un contexto, buscamos aquí la comprensión de una pedagogía viva e imaginativa. La disertación encontró en la Laguna un laboratorio vivo para pensar en una enseñanza educativa y para ejercer el pensamiento complejo. A partir de estudios e investigaciones anteriores, pude organizar lo que considero que se constituye como constelaciones de saberes que permiten dar continuidad a ese eje de investigación que empezó desde 1986 en el Grupo de Estudios de la Complejidad GRECOM. En la construcción de este trabajo, pude aprender valores que creo que son importantes para una educación compleja: la humildad delante de la vida; la abertura para diferentes lenguajes del mundo; el diálogo con la naturaleza; la apuesta en nuestras creencias; el sueño de resignificar a la realidad a partir del lazo entre la profundidad de nuestro ser y el mundo; el uso pleno de nuestras potencialidades imaginativas y creativas; y, finalmente, la vivencia intensa de los sentidos. Partiendo de ese aprendizaje, la investigación teórico‐práctica tuvo como elemento central el desarrollo de talleres sobre el tema del agua con alumnos de la enseñanza básicas de diversas series, y con la participación activa de dos profesoras de la comunidad de Areia Branca Piató. Fueron llevadas adelante experiencias que contemplaron una visión sistémica de la naturaleza, las fotografías, los atelieres, las clases de campo, el arte de educar, la narración de historias y sobre todo las enseñanzas del intelectual de la tradición Francisco Lucas da Silva

A educação escolar na comunidade negra de Sibaúma: a trajetória educacional da Escola Municipal Armando de Paiva

The black communities, nowadays known as quilombolas, have long been segregated in social and cultural distances in relation to other groups in the country. Gradually, the establishment of public policy has enabled the inclusion of these social communities in new instances, favoring the improvement of standards of learning. In order to know the route of the school in relation to its surroundings, this paper presents a reflection on the educational history of the Municipal School Padre Armando de Paiva, inserted in the context of afrodescendência (African descendants), in the community called Sibaúma, municipality of Tibau do Sul - RN, characterized as the object of this study. Methodologically, this study is limited in a descriptive research of the historical reconstruction of the school, a case considered worthy of analysis. From a reflection on the presence of African descent in Brazil and in Rio Grande do Norte, the study also presents information on education in Brazil. Finally, it presents the trajectories directed to the analysis of physical conditions, the dynamics of registration, and avoidance of repetition of its students and the qualifications of its teaching staff. Survey selected for analysis five-year academic periods, a series which began in the year nineteen eighty and ends in the year two thousand and ten

Zona adensável de Ponta Negra em Natal/ RN: as conseqüências decorrentes da lei complementar 27/2000 na visão dos moradores da área

The quarrel on the urban intensific use of determined areas of the city is carried through in some levels of the society, which had to the fact to bring direct influences the population that inhabits it. The question to become an area to intensific use, implies in determining that the local infrastructure has the capacity to take care of to a bigger amount of people, inhabitants or passers-by. In the quarter of Ponta Negra, in Natal city (state of RN), its condition of area to intensific use to the municipal Law 27/2000 happened due that it starts to allow a bigger level of occupation of part of the quarter. This law has a direct relation with the installation of a complementary infrastructure in the quarter, to put does not send to its complementation and maintenance, what it takes the consequences that are felt by the population. This work has as main objective the identification of the decurrent significant consequences of the creation of Ponta Negra s Intensific Use Zone, according to vision of the population of the quarter. The way followed for this involves the compatible bibliography research with the subject, analysis of documents that treat on the quarter, mappings of the area in search of a physical characterization and mainly, an application of questionnaire next to local population. In this questionnaire it is the main point of the necessary collection of data to the work, indicating the point of view of the population not only on the negative points, but also on the positive points that had happened since the creation of Intensific Use Zone. The answers indicate problems of natures social, infrastructure and enviromental, compatible with the problems of other areas that had passed the same for process, as point the studied bibliography, indicating imperfections in the planning process and maintenance of Ponta Negra s Intensific Use Zone
