Ecologia do fitopl��ncton impactado por cultivo de til��pia do Nilo, oreochromis niloticus, em tanques-rede no a��ude Ministro Jo��o Alves, Parelhas, Rio Grande do Norte

The dams are limnic ecosystems of great importance for its multiple uses, among them, water supply for the public and to culture of artisanal fish are most relevant. The aim of the present study is to evaluate the physical-chemical characteristics and the phytoplankton community in two chosen sites (Point 1 littoral zone of point source; Point 2 pelagic zone of non-point source) of the Minister Jo��o Alves dam, which is also known as Boqueir��o de Parelhas/RN. This represents the spatial distribution of the phytoplankton species in order to understand any possible alterations of the water quality and the phytoplankton composition in relation to the water quality originating from the impact of the tilapia, Oreochromis niloticus, culture. The study period also encompasses temporal variations exhibited in two seasons of an annual cycle, one during the dry season (Oct, Nov and Dec of 2008 and Jan of 2009), and the other rainy season (Mar, Apr, May and June of 2008) to extend the observation. The physicalchemical parameters, such as pH, temperature, electrical conductivity, concentration of dissolved oxygen were measured in situ and the values of the inorganic nutrients (nitrate, ammonium and orto-phosfato) and chlorophyll in the laboratory. The quali-quantitative analyses of the phytoplankton had been carried through sedimentation technique and the enumeration of the random of 400 cells, colonies and filaments counted using Sedgwick-Rafter counting chamber. The results of pH varied widely from the acidic to alkaline range with the minimum of 5.8 (�� 0.8) and the maximum of 9.2 (�� 0.7-0.8), at point 1 and 2. The dissolved oxygen content was higher in the rainy period than that in the dry period. The maximum electrical conductivity was of 1409 μScm-1 in point 1 and 431 minim of μScm-1, in point 2. There was a considerable alteration in the levels of inorganic nutrients such as nitrate-nitrogen, ammoniacal nitrogen and orthophosphate during the two cycles of study period. Phytoplankton assemblages presented a picture of alternate dominance among species Cyanobacteria, Bacillariophyceae and Chlorophyceae. The trophic state index diagnosed to the category of mesotrophic, which is based on the values of chlorophyll, total phosphorus and Secchi-disc measurements. The wind driven turbulence of the water column and the fresh inflow of water (flushing and dilution) during rainy season acted as constraint and did-not allow an exaggerated growth of the species of cyanobacteria. On the basis of the present we conclude that the culture of tilapias in cage-culture fails to produce pollution load that could compromise the quality of the water of the dam, probably be due to small dimension of the culture in relation to the size, volume of the water and the reservoir capacity support its own environment

Rede de atendimento socioeducativo: possibilidades e limites da garantia de direitos

The results of the research systematized on this analysis sought apprehend the linkage of the socio-educational service network, destined to adolescents who comply with socioeducational measure of confinement, in the region of the Serid�� of the state of the Rio Grande do Norte, especially in the city of Caic��, central town of this region. The achievement of this study was stimulated by the interest in unraveling the contradictory reality imposed by neoliberal State, sparing the guarantee of rights, especially to these teens, who are seen as authors of violations and are stigmatized by capitalist society. The research was carried in the period July-September 2013, under critical perspective, using the documental analysis and the observational techniques and interviews with professionals of the Educational Center (CEDUC), of the Unified Health System (SUS), of the Social Policies of Social Assistance, and of the State Department of Education, which should make the service network that gravitates around the National System of Socio-educational Services (SINASE). The Statute of Children and Adolescents (ECA) and SINASE define that the application of socioeducational measures cannot occur isolated of the public policies, becoming indispensable the linkages of the system with the social policies of social assistance, education and health. However, it was observed that the neoliberal logic of the capitalist State has developed broken, disconnected, focal and superficial social policies, who fail give effect to the rights acquired beyond the legal sphere. In this perspective, it is possible affirm that the everyday of the Brazilian poor teens is marked by the action of the State, which aims to control those who disturb the order of capital, who threaten the production, the market, the consume and the private property. This way, actions are promoted criminalizing poverty and imprint a legal action over this expression of the social issue to the detriment of social policies that meet the real needs of adolescents. Face of this reality, it becomes necessary to put on the agenda of the here and now to fight for rights, aiming at a broad public debate involving professionals, researchers and social movements in support of the viability of rights, which aims to support reflections and to strengthen ways to confront this social problem. With the approximations of this study, it was learned that the struggle for rights is a fight for another project of society, beyond what is laid.

Educa����o profissional e tecnol��gica de turismo no Brasil: an��lise atrav��s da percep����o de docentes da rede federal de educa����o

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.

Compara����o do controle do inversor trif��sico conectado �� rede com filtro LCL considerando o amortecimento passivo e ativo

Distributed generation systems must fulfill standards specifications of current harmonics injected to the grid. In order to satisfy these grid requirements, passive filters are connected between inverter and grid. This work compares the characteristic response of the traditional inductive (L) filter with the inductive-capacitive-inductive (LCL) filter. It is shown that increasing the inductance L leads to a good ripple current suppression around the inverter switching frequency. The LCL filter provides better harmonic attenuation and reduces the filter size. The main drawback is the LCL filter impedance, which is characterized by a typical resonance peak, which must be damped to avoid instability. Passive or active techniques can be used to damp the LCL resonance. To address this issue, this dissertation presents a comparison of current control for PV grid-tied inverters with L filter and LCL filter and also discuss the use of active and passive damping for different regions of resonance frequency. From the mathematical models, a design methodology of the controllers was developed and the dynamic behavior of the system operating in closed loop was investigated. To validate the studies developed during this work, experimental results are presented using a three-phase 5kW experimental platform. The main components and their functions are discussed in this work. Experimental results are given to support the theoretical analysis and to illustrate the performance of grid-connected PV inverter system. It is shown that the resonant frequency of the system, and sampling frequency can be associated in order to calculate a critical frequency, below which is essential to perform the damping of the LCL filter. Also, the experimental results show that the active buffer per virtual resistor, although with a simple development, is effective to damp the resonance of the LCL filter and allow the system to operate stable within predetermined parameters.

Boletim de Cultura da Câmara Municipal de ��vora, A Cidade de ��vora

Franz Joseph Haydn (1732-1809) confirma-se como o compositor modelar para uma avalia����o dos circuitos cosmopolitas da m��sica instrumental ao mais alto n��vel da aristocracia, complementando alian��as e compromissos selados pela partilha de um gosto musical. Entre outros estudos, refiram-se as conclus��es recentes de Stephen C. Fischer sobre a circula����o das Sinfonias de Haydn em Espanha. Neste trabalho o music��logo demonstra que a corte, a Casa de Alba e a Casa de Osuna y Benavente estavam entre as Livrarias da aristocracia europeia que recebiam novas obras de Haydn por via directa do compositor em finais do s��culo XVIII. Em Portugal tamb��m a reputa����o da m��sica de Franz Joseph Haydn se situou ao mais alto n��vel no per��odo compreendido entre as d��cadas de 1780 e de 1820, tanto na sinfonia, como m��sica de câmara, sobretudo para tecla.

[strategies For Integration Of Health Care Practices And Sanitary Surveillance In The Context Of The Implementation Of Rede Cegonha - A Brazilian Mother And Infant Health Care Network].

Mother and infant mortality has been the scope of analysis throughout the history of public health in Brazil and various strategies to tackle the issue have been proposed to date. The Ministry of Health has been working on this and the Rede Cegonha strategy is the most recent policy in this context. Given the principle of comprehensive health care and the structure of the Unified Health System in care networks, it is necessary to ensure the integration of health care practices, among which are the sanitary surveillance actions (SSA). Considering that the integration of health care practices and SSA can contribute to reduce mother and infant mortality rates, this article is a result of qualitative research that analyzed the integration of these actions in four cities in the State of S��o Paulo/Brazil: Campinas, Indaiatuba, Jaguari��na and Santa B��rbara D'Oeste. The research was conducted through interviews with SSA and maternal health managers, and the data were evaluated using thematic analysis. The results converge with other studies, identifying the isolation of health care practices and SSA. The insertion of SSA in collectively-managed areas appears to be a potential strategy for health planning and implementation of actions in the context under scrutiny.

Diretrizes curriculares nacionais para o ensino m��dio: avalia����o de documento

This text offers some contributions to the debate on the changes proposed to the National Curricular Directives to reform secondary education in Brazil. In the first part, the political and economic scene is evaluated as the context which generated the last stage of reforms in the educational field in the 90s. It questions the option for a model of structural reform (in the Brazilian case more restricted to the Program for Reform of Professional Education - PROEP) and of the curriculum, whose themes find their justification in the contemporary economic, social cultural and political context. It discusses the use of a model that bases itself on experiences developed in other countries and takes the international orientation of the multilateral organizations as its theoretical methodological reference, leaving out the peculiarities and injunctions of the Brazilian political administrative system. Such a policy measure can increase the tension and distance normally existing between government programs and the possibility of their real implementation in the school network. In the second part, it discusses the Resolution of the National Education Council, the Congress on Basic Education, no.3, of 16.698 that instituted the National Curricular Directives for secondary education, as well as the Legal Bases - Part I - of the National Curricular Parameters for secondary education. The analysis of official discourse takes Bardin's (1977, p. 209) proposals as its methodological reference for the models of structural analysis, seeking to make the implicit values and the connotations of the legal texts explicit

Quantifica����o de fluxos de merc��rio gasoso na interface solo/atmosfera utilizando câmara de fluxo din��mica: aplica����o na bacia do Rio Negro

Gaseous mercury sampling conditions were optimized and a dynamic flux chamber was used to measure the air/surface exchange of mercury in some areas of the Negro river basin with different vegetal coverings. At the two forest sites (flooding and non-flooding), low mercury fluxes were observed: maximum of 3 pmol m-2 h-1 - day and minimum of -1 pmol m-2 h-1 - night. At the deforested site, the mercury fluxes were higher and always positive: maximum of 26 pmol m-2 h-1 - day and 17 pmol m-2 h-1 - night. Our results showed that deforestation could be responsible for significantly increasing soil Hg emissions, mainly because of the high soil temperatures reached at deforested sites.
