Encalhes de Cetáceos ocorridos no período de 1984 a 2005 no litoral do Rio Grande do Norte, Brasil

Strandings of live or dead aquatic mammals constitute an important instrument to provide information regarding the occurrence, biology and ecology of these species. The aim of this study was to register the stranded species of cetaceans, the frequency and the spatial-temporal distribution of theses strandings during the period of 1984 to 2005, in the coast of Rio Grande do Norte. Data was acquired through the monitoring of strandings in the north, north-west and south coast of RN, and through information obtained from institutions and newspaper archives of the State. A total of 122 strandings of cetaceans were registered along the coast of Rio Grande do Norte. Of the 14 species of cetaceans registered, four species had higher frequencies: Sotalia guianensis (n= 65), Steno bredanensis (n = 6), Globicephala macrorhynchus (n = 6) and Physeter macrocephalus (n = 7). Out of 118 strandings, 93 occurred in the south coast (78.8 %), 23 in the north coast (19.5%) and 2 (1.7%) in the north-west coast of the State. The highest frequency of strandings occurred during the months of August to March and the maximum number of strandings occurred from 2000 onwards, as a consequence of the intense monitoring of the Pequenos Cetáceos Project in Rio Grande do Norte

Térmitas como bioindicadores de qualidade de habitat na caatinga, Brasil: há uma sintonia entre as variáveis estruturais dos habitats e as taxocenoses amostradas?

The composition of termite assemblages was analyzed at three Caatinga sites of the Seridó Ecological Station, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized sampling protocol for termite assemblages (30h/person/site) was conducted between September 2007 and February 2009. At each site we measured environmental variables, such as soil granulometry, pH and organic matter, necromass stock, vegetation height, tree density, stem diameter at ankle height (DAH) and the largest and the smallest crown width. Ten species of termites, belonging to eight genera and three families, were found at the three experimental sites. Four feeding-groups were sampled: wood-feeders, soil-feeders, wood-soil interface feeders and leaf-feeders. The wood-feeders were dominant in number of species and number of encounters at all sites. In general, the sites were not significantly different in relation to the environmental variables measured. The same pattern was observed for termite assemblages, where no significant differences in species richness, relative abundance and taxonomic and functional composition were observed between the three sites. The agreement between the composition of assemblages and environmental variables reinforces the potential of termites as biological indicators of habitat quality

Narrativas do Brasil nas memórias de Pedro Nava

This thesis is a translation of work of the Brazilian doctor, Pedro da Silva Nava (1903-1984), in particular, his memoirs and chronicles, articulated with the writings of medicine history, aiming to defend that the autobiographical narratives are sources of research capable of promoting discussions on the expansion of the present at the confluence of complex and unequal society in constant changing process as the Brazilian. The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecléa Bosi, Ítalo Calvino, José Willington Germano, José Maria Cançado, Lev Vygotsky, Marilena Chauí, Paul Ricöeur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil

Gestão dos resíduos sólidos no Brasil e seus rebatimentos em Natal, Brasil

O artigo apresenta a gestão dos resíduos sólidos no Brasil e seus rebatimentos na cidade de Natal/RN, verificando seus aspectos ambientais, econômicos e sociais. O fracasso da coleta seletiva revelado nos baixos índices de recuperação dos materiais; a baixa relevância da inclusão socioeconômica dos catadores que participam do programa assistencialista oficial; a inexistência de estratégias oficiais para que se minimize a quantidade de resíduos que se gera cada dia e o aumento exagerado dos gastos públicos, sobretudo com o tratamento dos resíduos no aterro sanitário, demonstram que a gestão de resíduos em Natal, conforme parâmentros da Política Nacional de Residuos Sólidos, objetiva o controle destes na cidade e a consolida- ção do tratamento finalista através do envio da quase totalidade dos resíduos coletados ao aterro sanitário

Diferenciais de mortalidade adulta por nível de escolaridade no Brasil e regiões

The study of mortality by various differentials has been an important tool to guide public health policies, due to better describing the events of deaths in a population. This research aims to seek disparities in mortality according to educational level, sex and adulthood in large Brazilian regions and consequently for Brazil as a whole. A vast literature has shown that people with more education tend to have lower risk of death. Studies on inequalities in mortality by level of education in Brazil are still very specific and has still known very little about Brazil about mortality according to educational level, due to lack of information about the well-filled school in the records of deaths arising from the Mortality Information System (MIS) of the Ministry of Health. This data source has shown improvement in the coverage of sub reports in the last decade, however, it has still perceived negligence in completing the question regarding schooling of death (about 30% of registered deaths in 2010 to Brazil, Given this scenario, this work contributes to the national literature on the behavior of adult mortality differentials having as proposed, using data from the new variable mortality of the 2010 Census (CD 2010), assuming the characteristics of education of the head the household for deaths occurring in the same. It is therefore considered that the probability of mortality is homogeneous within the household. Events of deaths were corrected only for the records come from households where the head possessed levels of schooling and Instruction Elementary Education No Incomplete and Primary Education and Secondary Education Complete Incomplete through the Generations Extinct Adjusted method. With deaths already corrected, probabilities of death were calculated between 15 and 60 years life, as well as tables by sex and level of education to all regions of Brazil. No que se refere às probabilidades de morte por idade, nas idades entre 15 e 60 anos as maiores probabilidades seguem um gradiente, maior probabilidade para os menos escolarizados. Results corroborate the literature, the more educated the population is, the greater the life expectancy. In all Brazilian regions, life expectancy of the female population is greater than that of men at all levels of schooling. With respect to probabilities of death by age between the ages of 15 and 60 years the most likely follow a gradient, most likely to the least educated. At older ages (from 70 years), this behavior has presented another pattern, the lowest level of education has the lowest odds in the regions, North, Northeast, South and Midwest, except in the Southeast region

Fundamentos dos cuidados com crianças e adolescentes: um olhar sobre o Rio Grande do Norte entre 1964 e 1988

Childhood and adolescence care has frequently caused theoretical and methodological discussions. At national level, the way of dealing with this public has always been on the agenda, either by maintaining a paternalistic treatment, or by coercive and repressive expression with which this public is treated. Given the above, this research presents a thorough study of social policies focused on children and adolescents in Brazil, with the overall purpose of investigating how this process of implementation of public policies for poor children and adolescents in the state of Rio Grande do Norte was. In previous studies, it was identified that there are no official records regarding the policy implementation process for this population in the state of Rio Grande do Norte. A retrospective study about the care towards children and adolescents in Brazil was held. It ranged from the XXVIII century, through the period of assistance, until the historical period in which the child started to be considered from the perspective of a policy. Thus, a certain period was framed, so that, through the historical research method, this study could focus on gathering data about the attention focused on childhood and adolescence in the state of Rio Grande do Norte, between the years 1964 and 1988. Data was listed from newspaper files that circulated in the state during period mentioned above. This time framing corresponds to the regency of the National Policy of Child Welfare. In the state of Rio Grande do Norte, the implementation of institutions such as FUNBERN and then FEBEM did not differ from the national standard, since many projects and care programs for poor children and teenagers were executed in this period. The implementation of these institutions revealed the concern of the state in solving the problem of “minors” regarding to situations of abandonment or "delinquency" which they were involved with. However, the kind of protection provided by the state toward this population was based on the current ideology that supported the political system at the time: the military dictatorship. Thus, the main way to provide care to this population was through its institutionalization, through taking children to daycare centres and adolescents to “reeducational” institutes for “minors”.

A educação popular para todos de uma cidade educadora (Natal, Rio Grande do Norte, 1957-1964)

This work has as a research subject of popular education policies of the city of Natal, Rio Grande do Norte, in the years 1957 to 1964. It aims to identify and analyze popular education policies developed and implemented by the Municipality of Natal in these years. To get the historical data, we establish as a guiding reserch question the following: Which elaborated educational policies were implemented by the Municipality of Natal in the years 1957-1964? and took over as the method Evidential Paradigm as proposition in Pinheiro (2009). This is anchored in documentary sources of Educational Legislation at National, State and Municipal levels as well as in the newspapers Folha de Tarde and Jornal de Natal; in existing documents from the archives of the Historical and Geographical Institute of Rio Grande do Norte (IHGRN), the Municipal Public Archives of Natal; iconographic sources; interviews and academic publications. In addition to these sources, we were inspired by the works of Aristotles (2011), Hobbes (2009), Freire (2011), Góes (1980), Germano (1989), Cortez (2005) and Galvão (2004). This research allowed us to understand that policies of popular education of Natal (RN) were based on a democratic educational practice, supported on three pillars, namely: participation and involvement of Natal population; construction and reconstruction of teaching practices in prioritizing their action programs to mass literacy and the training of lay teachers; and the democratization of culture. This historical process made Natal on educating city.

Efeitos de fungicidas alternativos em folhas de Carthamus tinctorius L. (Asteraceae), potencial espécie para cultivo em agricultura familiar

The currently main development model on global society is driven by an economic rationality that endangers the environment and social justice. More and more, attention to this way of production and consumption is increasing, boosting research for sustainable development, with an environmental rationality that can harmonize nature preservation and welfare of all socioeconomic classes. One of the efforts on this sense is changing the sources supplying the energy demand, replacing fossil fuels for renewable and cleaner sources, such as biofuels. Carthamus tinctorius (safflower) is an oilseed crop with potential for biodiesel production, with good oil yield and chemical profile, allied to good adaptation to climates such like the northeastern semiarid lands of Brazil. With public policies fomentation, the use of this species may be an interesting alternative for family farming. In farming in general, the use of pesticides to prevent and combat diseases and plagues is common, which is not a sustainable practice. Thus, there are researched alternative, less dangerous substances. In this study, it was aimed to assess if neem (Azadirachta indica) leaf extract (20% m/v) and Bordeaux mixture (copper sulfate) have effects on safflower. It was also aimed to verify acceptance of farmers on safflower crop in Apodi, a municipality in Rio Grande do Norte state, Brazil, in view of it being localized in the aimed region for this crop cultivation. Besides that, understanding that the farmers’ knowledge and inclination to adopt the crop is fundamental for the introduction of this species and socioeconomic growth due to its exploration. In addition, a booklet with basic information on safflower was produced. In the field experiment, the fungicides were pulverized on plants cultivated in field experimental plots, with collection of leaf samples for analysis on anatomy, cuticle, and epicuticular wax morphology, the protective layer that interfaces with the surrounding ambient. In Apodi, forty-five farmers from Potiguar Cooperative of Apiculture and Sustainable Rural Development (COOPAPI) underwent semi-structured interviews, which also addressed their assessment on currently cultivated crops and perception of pesticide uses and sustainable alternatives. After comparing using analysis of variance, it was found that there was no difference between treatments in the experiment, as well as no anatomical or morphological modifications. Safflower acceptation among farmers was wide, with 84% of interviewees believing in a perspective of good incomes. The current scenario, comprised of low crop diversity, fragile in face of droughts and plagues, can partially explain this opinion. The booklet was effective in catching people attention for the species potential. There was wide acknowledgement on the importance of alternative pesticides, justified by health security. Based on the assessed parameter in the results of this research, the treatments here utilized may be recommended as fungicides for safflower. Given the crop susceptibility to fungi in heavy rainy period, it is advised that its potential introduction on the region shall be focused on semiarid areas.

Consórcio de cártamo e feijão caupi: alternativa para a produção de biodiesel na agricultura familiar

The new development strategies should operate mainly in the areas of energy efficiency and sustainable agriculture. Thus, the substitution of fossil fuels with biofuels, such as biodiesel, is increasingly on the agenda. The cultivation of oilseed plants for biodiesel production must take place in integrated systems that enable best environmental benefits and are more economically significant. The objectives of this study were to assess the morphological, anatomic, and physiological characteristics of safflower (Carthamus tinctorius L., promising oilseed for biodiesel production) grown in monoculture and intercropping with cowpea bean (Vigna unguiculata L. Walp.); and identify socioeconomic family farmers and verify their acceptance about safflower as an energy crop. The methodology used for the analysis of safflower growth in monoculture and intercropped with beans, were morphoanatomical and histochemical analyzes, made with samples of plants grown in the field in two cropping systems throughout the range of the life cycle of these plants. There were no changes in growth and anatomy of plants, even in the consortium, which is satisfactory to indicate the intercropping system for those crops and can be a good alternative for the family farmer, who may have safflower as a source of income without giving up planting their livelihood. To check the acceptance of safflower by farmers, interviews were made to family farmers by Canudos agrovila in Ceará-Mirim/RN. It was noticed that many of them accept the introduction of safflower as oil crop, although unaware of the species, and that, being more resistant to drought, safflower help in the stability of families who depend on the weather conditions for success their current crops. In general, it is concluded that safflower has features that allows it to be grown in consortium for biodiesel production combined with the production of food, such as cowpea, and can be used enabling better development for family farmers.

A argamassa da casa e do conflito: os usos políticos da construção da cidade da esperança feitos pelo grupo aluizista (1964-1966)

Nous nous proposons à analyser les usages politiques que le groupe lié au gouvernement Aluízio Alves a fait d’un complexe d’habitation s’appelé Cidade da Esperança, qui a été construit en Natal dans les années 1960. Ce nouvel espace a été utilisé pour solutionner la crise d’habitation dans la capital, dont le número de personne augmentait fortement. Cette élévation, néanmoins, n’a été pas accompagné pari passu pour l’expansion de l’offre des maisons pour le marché et ce pénurie se transformer dans un problème social e politique. La Cidade da Esperança, alors, a été une réponse de l’État à la population et entre ces dynamiques, le groupe du gouvernement Aluízio Alves a su explorer la question parce qu’il a utilisé l’espace pour négocier avec differents agentes sociaux et il aussi a réussi élire Agnelo Alves, le diretor de la construction, à maire de Natal. Par la construction de cette analyse nous utilisons le journal gouvernamental Tribuna do Norte et le journal catholique A Ordem. Ils ont représenté dans ces pages les problèmes de pénurie des maisons et aussi les appropriations de la Cidade da Esperança. Pour ça nous pouvons reconstruire ces processus historiques. Pour les journaux est possible connaître du quotidien des travaux, les actions des sujets réponsable et les tensions politiques du groupe aluizista avec l’autre lié à Dinarte Mariz. Ainsi, ils possibilites l’étude de l’utilisation de la Cidade da Esperança dans l’intérieur d’une réseau des tensions et l’examen de la recherche pour legitimité dans un champ politique très poralisé.

(A)cerca do espaço: a nacionalização da questão agrária pelo MST (1984-2002)

This work has as objective to analyze the social movement called Movimento dos Trabalhadores Rurais Sem Terra and their relation to land reform from the idea of nation. In the decade of its emergence, 1980, Brazilian nationalism was deeply tied to aspirations for democracy and this consisted of a kind of political language of the period that included not only the MST, but also conservative sectors of Brazilian politics. The MST then develop a way to realize their different social function of the movements that preceded it as the Ligas Camponesas, incorporating the element of the nation as political capital to strengthen their practice. This relationship will be studied from a debate on contemporary Marxism and its key concepts.

Determinação da condutividade do solo para agricultura: uma metodologia utilizando propagação de ondas AM

Agriculture is an essential activity to the human development, the tendency is that their need to increase according to the increase in world population. It is very important to take the maximum performance that is possible of each land without degrading it, a frequently monitoring is essential for the best performance. The purpose of this work is, nondestructively, to monitor the surface electrical conductivity of the soil in a demarcated area, as on a plantation, using low frequency radio waves. The conductivity is directly linked to the amount of water in the area and nutrients, therefore a periodic or even permanent monitoring increases significantly the efficient of the use of the soil. They will be used long-wave radio transmission or medium whose main characteristic to spread over the surface of the earth. It is possible to choose an AM radio with location, frequency and power of the transmission known or generate the signal. The studied method computes the conductivity of the ground in a straight line between two measured points, so it can be used in smaller or larger size fields. Measurements were carried out using an electromagnetic field strength analyzer. The data obtained in the measurements are processed by a numerical calculation program, in our case Matlab. It is concluded that the recommendations of the ITU (International Telecommunication Union) on the conductivity of soil in Brazil is far from reality, on some routes the recommendations indicate the use of the electrical conductivity of the soil 1 mS/m, while the measurements was found 19 mS/m. With the method described a precision farmer, once initial research for about a year, can monitor the humidity and salinity of the land, with the ability to predict the area and the most suitable time for irrigation and fertilization, making management more efficient and less expensive, while optimizing water use, natural resource increasingly precious.

Movimento de educação e cultura popular no Brasil dos anos 1960: resistência desfeita

In this work we defend the thesis that the movements of culture and popular education in the 1960s in Brazil, manifested itself into resistance to hegemonic thought, coming from the North, which reduced the popular individuals and their knowledge to the ignorant condition. The focus of our study lies on the resistance produced by these movements in the history of the Country. We used as theoretical reflective foundation the thinking of Boaventura de Sousa Santos and his thesis about the construction of rationalities focused in the fight against indolent reason and the deconstruction of the inferiority in the colonized plan. But the analysis also favors approaches of other authors in the proportion that deals with the action of social actors of culture and popular education movements that have marked their presence in the public space, whose views and interests were invented and reinvented constantly in the relacional game. From the point of empirical view, the research makes use of bibliographies and written documentary sources such as newspaper articles, speeches, statements, manifests and documents like these. The research intends to seek in the past the understanding of those Movements in an effort to enable the viewing of certain remnants of the past that have relevance as social and academic wealth of experience. From the popular and the local, movements of culture and popular education in the 1960s, they overcame the barriers of invisibility and raised Itself to the plan of the global history, when they began to become protagonists of their own history, until their dreams were buried by the 1964 tragedy.
