Avaliação da eficiência de filtros anaeróbios na remoção de coliformes fecais e ovos de helmintos

The technology of anaerobic reactors for sanitary wastewater treatment has been extensively developed in Brazil, and today it is practically consolidated. They present several advantages, such as low construction and operating costs, and low sludge production, the anaerobic reactors are an attractive alternative to minimize problematic lack of basic sanitation in urban areas, and also of the rural areas. The anaerobic filters have been widely used in Brazil. It produces an effluent with low concentration of organic matter and solids suspended, besides conserving the nutrients, therefore, it is good for use in irrigation, but the practice must be associated with knowledge of the pathogens presence. The main objective of this study was to evaluate the efficiency of anaerobic filters in removal faecal coliforms and helminth eggs, and to verify if the effluent can be used for agricultural purposes, according to the World Organization of Health (WHO, 1989). The protocol used to enumerate helminths eggs was the modified Bailenger method, (Ayres and Mara, 1996) recommended by WHO for evaluation of raw effluent and treated effluent. The membrane filtration method was utilized to determine the concentrations of faecal coliforms. Three different systems of sewer treatment composed by anaerobic filters were analyzed. The results, in a general analysis, showed that all the researched systems reached a larger removal than 93% to helminth eggs, resulting in an effluent with smaller average than 1 egg/L. One of these systems, Sistema RN, reached a larger removal than 99%, confirming the good performance of the anaerobic filters in removal helminths eggs. Even with low concentrations of eggs in the influent, the filters were capable to remove this parameter efficiently. About faecal coliforms, it was observed for all the researched systems an effluent with 106 CFU/100mL. The high concentrations to faecal coliforms in the effluent just allow reuse for restricted irrigation, in agreement with the guidelines of WHO. Although the researched systems have not removed faecal coliforms efficiently, the results indicated a good efficiency of the anaerobic filters in removal helminth eggs

História, memória e espaços: experiências dos ex-combatentes de Parelhas-RN na defesa do litoral brasileiro durante a Segunda Guerra Mundial

The present essay has how I aim to analyse the memories of the ex-combatants of Parelhas-RN, specially of the components of the Força de Vigilância e Segurança do Litoral - FVSL, protagonists of the Brazilian participation in the scenery of the Second World war. Along this we looked to understand in which surrounding geographicalpartner these men were living before the War and what were the consequences of a brusque change of space owing to the convocation for the Armed Brazilian Strength in that historical context. The defense of the Brazilian coast during the War was not a so simple task, I have in mind the precariedade logistics of the Armed Strength, the attacks of submarines of the Axle that killed hundreds of civilians and Brazilian soldiers and the net of espionage mounted by Germany in Brazil. Leaving from the notion of collective memory and estrangement in Maurice Halbwachs, we will use the oral history like principal methodology, with the end of rescue these underground memories what also will make possible us the vision realizes that the protagonists themselves have of the event, besides the use of documents, photos, maps and any sort of fountains that make possible us to rebuild the scenery of Parelhas in the beginning of the War and the trajectory of life of his veterans

Dinâmicas centrípetas e centrífugas na formação do Estado monárquico no Brasil: o papel do Conselho Geral da Província de São Paulo

O presente artigo avalia a formação e o funcionamento do Conselho Geral da Província de São Paulo durante o Primeiro Império. Organismo previsto na Constituição de 1824, com funções que podem ser consideradas um embrião do Poder Legislativo provincial, organizou-se efetivamente na província de São Paulo em 1828, quando o governo de D. Pedro I já se desgastava. O significado de sua existência no contexto das dinâmicas centrífugas e centrípetas atuantes na primeira construção do Estado no Brasil independente constituem o principal objetivo da presente análise.

Imunoexpressão de vegf-c, vegfr-3 e hif-1α e mensuração da densidade linfática em carcinomas epidermóides de lábio inferior metastáticos e não-metastáticos: uma relação com parâmetros clinicopatológicos e prognósticos

Squamous cell carcinoma of the lower lip is among the most common malignant tumors of the oral and maxillofacial region, with good prognosis in more than 90% of patients with 5-year survival. In these carcinomas, the development of lymph node metastasis decreases the prognosis and it has been associated with the formation of new lymphatic vessels. It has been suggested the important role of vascular endothelial growth factor-C (VEGF-C), the receptor type 3 VEGF (VEGFR-3) and hypoxia-induced factor 1 (HIF-1) in this process. The aim of this study was to evaluate the immunoexpression of VEGF-C, VEGFR-3 and HIF-1α and correlate with intra and peritumoral lymphatic density in squamous cell carcinomas of the lower lip metastatic and non-metastatic. The sample consisted of 50 cases of squamous cell carcinoma of lower lip, of which 25 had regional lymph node metastasis and 25, absence of metastasis. The percentages of cells immunostained for VEGF-C, VEGFR-3 and HIF-1α in front of tumor invasion and in the center of tumor were evaluated. Microvessel density lymphatic (MDL) was determined by the counting of lymph microvessels immunostained by the anti-D2-40 in five fields (200×), in an area of evaluation with 0.7386 mm2. The invasion of the lymph vessels by malignant cells was also evaluated. Immunostaining was correlated with the presence and absence of metastasis, TNM clinical stage, local recurrence, disease outcome (remission of injury or patient death) and histological grading. The analysis of intra and peritumoral lymphatic density showed no significant association with clinicopathological parameters and immunoexpressions of VEGF-C, VEGFR-3 and HIF-1α (p > 0,05). There was a weak positive correlation, significant, between intra and peritumoral lymphatic density (r = 0,405; p = 0,004). VEGF-C showed no significant association with clinicopathological and prognosis parameters (p > 0,05). For VEGFR-3, there was scarce membrane staining and intense and homogenous cytoplasmic staining in neoplastic cells. Percentage of positive cytoplasmic VEGFR-3 in center of tumor, exhibited a statistically significant association with metastasis (p = 0,009), patient death (p = 0,008) and histological grades of malignancy proposed by Bryne et al. (1992) (p = 0,002) and World Health Organization (p = 0,003). A low positive correlation was statistically significant between the immunoreactivity of VEGFC and VEGFR-3 cytoplasmic (r = 0,358; p = 0,011) and between the percentage of positive cytoplasmic VEGFR-3 in front of tumor invasion and in the center of the tumor (r = 0,387; p = 0,005) was also demonstrated. There was no association between HIF-1α, clinicopathological and prognosis parameters, and VEGF-C and VEGFR-3. The percentage of nuclear positivity for HIF-1α was significantly higher in cases without invasion of peritumoral lymphatic (p = 0,040). Based on the results we can conclude that most cytoplasmic expression of VEGFR-3 in center of tumor in metastatic cases, high degree of malignancy and poorly differentiated, contributes to poor outcome of squamous cell carcinoma of the lower lip, including patient death. Intra and peritumoral lymphatic density seems to be not associated with lymph node metastasis in these carcinomas

Efeitos do substrato e da densidade populacional sobre as atividades comportamentais e níveis de homócitos em relação à densidade em Litopenaeus vannamei (BOONE, 1931)

Carciniculture in Brazil occupies world-wide prominence due to shrimp culture, and the state of Rio Grande do Norte has presented the best results in the culture of the Litopenaeus vannamei in the last decade. This species has been shown to adapt easily to different environments and is between the five most cultivated penaeids of the world. The ponds are usually constructed in areas close to water courses and estuaries. Stock density and substrate ponds can pollute environment, causing losses in the growth and survival of the shrimps, being considered stress factors. Shrimps in inadequate densities and substrates can result reduced productivity of the farm; and favor diseases. So, it is important to verify how these variables influence the development of the animals in the culture farms. Our objective was to study the influence of the type of substrate and the stock density on the behavior and haemocyte count of the L. vannamei. Individually marked juvenile shrimps were kept in aquaria with 30 L of seawater and continuous aeration, in 12L-12D photoperiod. They were observed through Ad libitum and focal sampling instantaneous methods during thirty days, five times per week, six times per day (8:00 to 18:00) in windows of 15 minutes every two hours. The marking of carapace permitted quantifying molting and the feeding was supplied three times a day. Two experiments were carried out: the first one tested animals in the three different substrates (fine sand, smaller rocks-SPP and biggest rocks-SGR) with 33 shrimp/m2. In the second one, the animals were tested in three stock densities (26, 52 and 66 shrimp/m2) in fine sand substrate. At the end of experiment, biometry (first and second ones) and haemocyte count (second one) were made. The behavior of the L. vannamei seems to have been influenced by substrate and stocking density. In low granulometry of the substrate; the exploratory behavior became more frequent and inactivity of the shrimps was reduced. Burrowing was registered in sand substrate, specially in the initial period of the day. Cleaning was gradually higher along the day, presenting the biggest levels as the dark phase approached. The ingestion of feeding was more frequent in low density, and the animals were bigger and heavier at the end of the experiment. In the fine sand condition, the animals presented better growth, probably associated with the burrowing. The molting was equivalent in all types of substrate, but it was more frequent in high densities. Mortality of the shrimps was more frequent in high densities, and cannibalism and diseases were also registered in that condition. The clinical signals were similar to the ones of infectious mionecrosis (IMNV), generally associated with environment and physical stress. The haemocyte count was low for the hematologic standards of the penaeid, which we attributed for greater dilution of haemolymph in the postmolting phase. Smaller shrimps presented lower levels of haemocytes in relation to the bigger animals, count was also low in 26 shrimp/m2 density. The study demonstrates that stocking density and the granulometry of the substrate can affect the welfare, the health and the behavior of the L. vannamei. The sand substrate and low stocking density can be important tools in the management systems of shrimp production

Arranjos urbanos e subjetivos contemporâneos na invenção de territórios turísticos

We seek consistency empirical and analytical rigor to the concept of touristification in the course of the contemporary arrangements of subjectivity and urbanity stations through a landscape of social (dis)encounters between residents and foreigners living in the capital of Rio Grande do Norte, Natal. In the last three decades the city has become a major destination country for national and international tourism, making tourism an important monitor of choreography in search of synchrony between cities and subjectivities, orchestrated by the cyclical crises and the relentless battle for systemic capitalistic expansion and survival. We proceed with an ethnographic and cartographic inspiration in Ponta Negra, where the waterfront redevelopment in 2000 conducted by the government, influenced the implementation of various establishments, services and practices related to the construction of Natal s major industry hub of tourism and entertainment. We proposed an arch-genealogy of touristification inspared on Michel Foucault analytical perspective, increased by authors in confluence or in different theoretical and methodological approaches, among which stand out Karl Marx, Gilles Deleuze and Felix Guattari, Michael Hardt and Antonio Negri. The reflections that initially turned to the advancement of the sphere of consumerism as the issue capable of articulating the developmental trajectory of the capitalist system and the practice of tourism, promoting some effects (un)desirable in the conflictual dynamics of the condition of the district of Ponta Negra, territory each again (re) produces the designs to meet the consumption by affluent portion of the population and foreign, encountering social exclusion and inclusion differentiated a growing trend. We go forward with an analysis of the "liberation of desire" phenomenal features of the process of producing subjective, providing a breakdown of the recent world s financial crisis initially, but proved social and political crisis also, through a plot derived from the operation of real estate speculation, which Natal is mainly caught through touristification, showing the outlines of a generalized crisis in establishing a new order buoyed by the emergence of a context "biopolitical" since it is a major route that uses the capital to survive and expand, while guiding the process of "strategic beautification" held in Ponta Negra, problematized by us. We conclude by assessing the appropriateness of proposing on further analysis to explore the establishment of a "new social ontology in terms of interference touristification ongoing and the constitution of a "new order" local/global, away from that characterize a system's capitalist overcoming, try to give emphasis in the current stage of the radicalization of a capitalistic utopia

A experiência de adolescentes portadores de diabetes Mellitus Tipo 1: seus significados e sentido

Worldwide, the diabetes mellitus is considered a serious problem of public health; it also involves high costs for its treatment and its complications. Even though the onset of diabetes mellitus type 1 is on 5% to 10% of the diabetic population, it is the most aggressive type of anifestation; furthermore, it is the commonest chronic disease in childhood and adolescence. Such data show the importance of understanding the development of this disease from the moment the individual perceives it, according to their experience, observing the complexity of the phenomenon thoroughly. This study aimed to comprehend the experience of the adolescent with onset of diabetes mellitus type 1 in order to learn how these young individuals perceive and reason their place in the world when they experience this illness. The methodological strategy was based on qualitative research of phenomenological inspiration. We applied the main ideas of heideggerian ontology and some concepts of existential phenomenological psychology to guide our reflexive path. The participants were 10 young individuals (06 female and 04 male), ages between 15 and 18, under treatment in the city of Recife, Pernambuco. The methodological resource was the narrative, which allowed us access to the adolescents experience. The comprehension of the reports was based on the heideggerian hermeneutics, whose priority is the interpretation of the meaning expressed by the participants speech. The results showed that factors such as social, family, economic and cultural context greatly influence the perception and the way the individuals deal with, perceive and reason their experience. We noticed that the diabetes type 1 may often represent a limitation, but it does not make it impossible to be part of the world with others. The data show a significant affective ambivalence regarding the content more directly related to the disease. This demonstrates the unique way which each one gives meaning and reasons their condition of existence. This research points out the need to understand the complexity of this phenomenon in a more complete manner, considering the adolescent in their timely and historical context. We believe we can encourage thinking that may become actions which are more fit to the reality researched regarding all the parties involved with the subject, such as health professionals, adolescents, family, support programs and public health policies

A humanização no parto e no nascimento: os saberes e as práticas no contexto de uma maternidade pública brasileira

The practice of medicine related to the gestational processes tend to be organized according to the context and the place of work, being thus dependent of the conditions both social and economical, and of the physical structure and the functionality of the services. The high mortality rate in this process has diminished, since 1986, the study made by the World Health Organization (WHO) as to the technical aspects and the social inequalities that influence this situation in different geographical contexts. This culminated recommendations that proposed the reorientation of the dynamical practice of medicine, with a focus on the safety of maternities. Brazil adopted, in the year 2000, the suggestions of the OMS, emphasizing the humanization as the main reason for these actions. However, this discussion tends to not consider the problems caused by the social inequalities and the epidemiological and social conditionings that define the actions of the Unified Health System (Sistema Único de Saúde SUS). In this area, this research seeks to analyze the practices, cares taken, and the universal symbol that promotes and rewards the assistance to the birth of children by the SUS. Besides the analysis of the public documents that deal with this subject, an ethnographic study was developed in a maternity in Natal/RN, considered a model of humanization after receiving the Galba de Araújo prize in 2002. In this stage, the methodological strategies were observed, and the focus of the individual interviews with workers and users of this service. In the analysis of the data, it became evident that the different professional workers and women who gave birth, tend to show concern of the standards the delimit production and reproduction of the practice of medicine, as they favor the absence of a critical posture of the actions destined to the population. Besides this, if became evident that the institutional difficulties associated to the economical, cultural, and political problems also difficult the involvement and the reflection of the workers in favor of assisting changes of the process. There is also a utilization of a perspective prescriptive of humanization in the everyday life of the social workers, without reflection of its meaning. Some workers present, in their statements, a preoccupation with the social and economical aspects that affect the practice of medicine, and with the limitations of the humanization discourse that disarticulates the necessities of those involved in the process of formation, and soon tend to return to the discussion of humanization while a kind practice characterized by the minimization of the interventionist actions. Now the users of the system show themselves before the dynamic of the services, submitting themselves to what is offered while assistance, without questioning and/or reflecting about their usual shortages. Therefore, to think of changes in the know and do of the practice of medicine destined to the birth of children implies reflection on the quotidian production of these practices and of the social contexts that influence the process of assistance in the practice of medicine. Herein it would be possible to predict the appropriation, by different workers concerning their exasperations and necessities, making them active in the pursuit of their rights as citizens

Serviço Social e Política: uma análise da participação dos assistentes sociais no Conselho Regional de Serviço Social 14ª região

This paper analyzes the political participation of Social Workers at the Social Service Regional Council Region 14th. The theoretical and methodological framework of this investigation has as its perspective the totality of social life and its determining relations within the object of study. To the production, analysis and collecting of data it was used a qualitative approach considering a bibliographical and documental research as well as a series of twelve interviews with 2005-2008 and 2008-2011 managing counselors of CRESS/RN. It was also used the data obtained from other special interviews held with the social workers in the period between 2007 and 2008. The results of this study allow and affirm the political dimension of Caseworkers and the CRESS/RN as a space of political activity with opportunities for effective and collective elaboration of strategies in order to reach the fulfillment of the ethical and professional policy of the Social Work. From a historical viewpoint, the beginning of this process is marked by the struggle for democracy, the end of military dictatorship, the establishment of the State of Human Rights. The Democratization of the so called Federal Council of Social Workers and its Regional Councils of Social Workers, CFAS / CRAS, respectively, area a result of the participation of the category in an effort to fight for democratization in Brazil. The objective of this research, so, is to understand which the socio-historical determinants are, that focus objectively and subjectively in the demobilization of social workers in CRESS Region 14th - in the contemporary and historical context. Among the results obtained we identified the ignorance of some professional workers and also of some advisors, regarding the existence and the role of the Council, as well as the commercialization of Education that compromises the quality of the professional training in its theoretical and methodological, ethical and political dimensions. According to our understanding, this shows a the presence of a non-critical professional profile based on a false reality, on the precariousness of employment contracts which undermine the political organization and submit the worker to various social exploring mechanisms such as double shift and ultimately the fragility of the management of the Regional Council -, as a consequence of the offensive capitalist system that ideologically invests to stop the political organization founded in a critical and democratic perspective. The low participation of some advisors and, in general, the category in CRESS / RN, despite its objective conditions, is a reality and it is presented to us as a challenge to future managements and policy consolidation to society. Inasmuch as the category intends to guarantee the high quality of its social workers, the demands of future counselors, their skills and abilities in dealing with regulatory issues, administrative policies that pervade the everyday life of CRESS / RN are necessary

Tracoma em crianças do ensino fundamental no município de Bauru: Estado de São Paulo, Brasil

OBJETIVO: Foi realizado um estudo transversal, por amostragem de escolares, frequentadores das escolas estaduais de Bauru, São Paulo, com o objetivo de detectar possíveis portadores de tracoma. MÉTODOS: Foram examinadas 1.749 crianças do ensino fundamental, de 6 a 14 anos, durante o ano de 2005. As escolas foram escolhidas por sorteio, de acordo com o número de estudantes e com a localização da escola dentro do setor da cidade (centro, região intermediária e periferia). O diagnóstico dos casos foi clínico, seguindo as normas da Organização Mundial de Saúde (OMS), confirmado laboratorialmente pelo método da imunofluorescência direta para detecção de Chlamydia trachomatis. RESULTADOS: A prevalência de tracoma inflamatório foi de 3,8%, tendo sido diagnosticado tracoma folicular em 3,7% e tracoma intenso em 0,06% das crianças examinadas. As crianças com tracoma moravam principalmente na região intermediária e periférica da cidade, áreas onde o fornecimento de água pode ser descontínuo e o tratamento do esgoto pode estar ausente. Um programa de controle foi desenvolvido e os comunicantes foram diagnosticados e tratados. CONCLUSÃO: A prevalência de tracoma inflamatório em Bauru - Estado de São Paulo - é de 3,8%. Além da oportunidade de reconhecer e tratar os portadores e contatantes, os autores realçam o fato positivo da mobilização da comunidade bauruense no sentido de prevenir a cegueira pelo tracoma.

Prevalência e localização espacial dos casos de tracoma detectados em escolares de Botucatu, São Paulo - Brasil

OBJETIVO: Avaliar a prevalência de tracoma em escolares de Botucatu/SP-Brasil e a distribuição espacial dos casos. MÉTODOS: Foi realizado um estudo transversal, em crianças de 7-14 anos, que frequentavam as escolas do ensino fundamental de Botucatu/SP, em novembro/2005. O tamanho da amostra foi estimado em 2.092 crianças, considerando-se a prevalência histórica de 11,2%, aceitando-se erro de estimação de 10% e nível de confiança de 95%. A amostra foi probabilística, ponderada e acrescida de 20%, devido à possível ocorrência de perdas. Examinaram-se 2.692 crianças. O diagnóstico foi clínico, baseado na normatização da Organização Mundial da Saúde (OMS). Para avaliação dos dados espaciais, utilizou-se o programa CartaLinx (v1.2), sendo os setores de demanda escolar digitalizados de acordo com as divisões do planejamento da Secretaria de Educação. Os dados foram analisados estatisticamente, sendo a análise da estrutura espacial dos eventos calculadas usando o programa Geoda. RESULTADOS: A prevalência de tracoma nos escolares de Botucatu foi de 2,9%, tendo sido detectados casos de tracoma folicular. A análise exploratória espacial não permitiu rejeitar a hipótese nula de aleatoriedade (I= -0,45, p>0,05), não havendo setores de demanda significativos. A análise feita para os polígonos de Thiessen também mostrou que o padrão global foi aleatório (I= -0,07; p=0,49). Entretanto, os indicadores locais apontaram um agrupamento do tipo baixo-baixo para um polígono ao norte da área urbana. CONCLUSÃO: A prevalência de tracoma em escolares de Botucatu foi de 2,9%. A análise da distribuição espacial não revelou áreas de maior aglomeração de casos. Embora o padrão global da doença não reproduza as condições socioeconômicas da população, a prevalência mais baixa do tracoma foi encontrada em setores de menor vulnerabilidade social.

Contextualização da pesca mundial de lagostas e características de comercialização de Scyllarides spp. E Panulirus spp. na Baixada Santista, estado de São Paulo, Brasil

This study aimed to contextualize the world's lobster fishing and identify the characteristics of their trades in Santos region (SP). For this purpose, were realized surveys about the captures of 56 years referring the families traded in the world through the informations supplied by the FAO (Food and Agriculture Organization). To State of São Paulo, consults were made in the data base Propesq (Fishing Institute) about the fishing and prices. Besides interviews in fishmonger, businessmen of fishing and restaurant, we observed the trade and the economical potential compared the lobsters Scyllarides spp. and Panulirus spp. The worldwide the family Nephropidae is the one that has been presenting bigger growth in the captures from 1950 and the one that has the biggest observed captures, the Palinuridae showed a little growth of the captures up to the 80' years, and leaving from there it is oscillating without many expressive changes; Scyllarides began to stand out as fisheries only 70' in Asia, precisely where the other two Families had low catches proportional. In the State of São Paulo, two types of lobsters are sold in Baixada Santista, with conspicuous differences in prices between them. There is also a difference in the flow of trade in relation to active fishing gear. Traders notice a decrease in both abundance and size of individuals of both genders and a clear preference to sell the slippers lobsters (Scyllarides spp.) both for the quality of meat as the lowest price.

O Banco Mundial e modelos de gestão educativa para a América Latina

Este artigo empreende a análise do discurso dos capítulos cinco e sete do documento do Banco Mundial: Para além do consenso de Washington: a importância das instituições, identificando e questionando a proposição de modelos teóricos para as reformas da administração pública e educacional na América Latina, com fundamento em autores preocupados em examinar o conceito de modelo teórico. A intenção é discutir as categorias envolvidas, suas ambigüidades e seu caráter inovador/conservador e definir se as propostas contidas no texto referido são nacional e regionalmente adequadas, se detêm o poder de transformar a realidade ou constituem apenas algo mais sobre a mesma coisa ou, pior, traduzem o resgate/elogio de modelos remodelados, inspirados na teoria empresarial, que alimentam a crítica dos acadêmicos regionais há décadas.
