Diversidade de paronellidae (collembola, arthropleona, entomobryoidea) no nordeste brasileiro, com ênfase em áreas úmidas da caatinga

Paronellidae is among the most diverse and distinctive components of epiedaphic Collembola in tropical countries. However, only 15 species of the family were recorded in Brazil, and only two of them were record in northeast region of the country. This condiction is clearly related to low sampling efforts and lack of specialists working with the group. Due to this reality, this work aimed to study the Paronellidae fauna, under a taxonomic point of view, in six distinct environments in Northeastern Brazil (from Alagoas, Bahia, Ceará, Piauí and Paraíba states), five areas of Caatinga and one from Atlantic Rain Forest biome. Collections were made during the rainy season on each area. The specimens were analyzed under stereomicroscope and mounted in glass slides for microscopy. The specimens identified as Paronellidae had their occurrence recorded and five new species were described. An identification key to the brazilian genera of the family was also prepared. Twelve species of Paronellidae were recorded for the first time to Brazil: Campylothorax mitrai; Lepidonella. sp. nov. 1; Lepidonella sp. nov. 2, Lepidonella sp. nov. 3, Lepidonella sp. nov 4, Lepidonella sp. nov. 5; Dicranocentruga sp. Nov. 1; Dicranocentruga sp. Nov. 2; Dicranocentruga sp. Nov. 3; Paronella sp. nov.1; Serroderus sp. nov.1 and Trogolaphysa. sp. 1, where C. mitrai, Lepidonella. sp. nov 1, Dicranocentruga sp. nov 1, Dicranocentruga sp. nov 2 and Dicranocentruga sp. nov 3 were described. Serroderus and Dicranocentruga genera were recorded for the first time to Brazil. The description of Lepidonella sp. nov 1 also represents the first description of a species of the genus for the country. The data presented show a high potential species richness to Paronellidae, not only in the northeast region, but as in Brazil. In fact, with the records presented in this work, the number of recorded species of Paronellidae in the country increased by 80%. The study of this particular fauna may direct environmental conservation policies, especially in areas of Caatinga

Colêmbolos (arthropoda: hexapoda: collembola) numa área de caatinga do nordeste brasileiro

Edaphic ecosystems are the basis for the production of terrestrial biological resources and their dynamics affect not only the natural environment but also society and their economic activities. In Caatinga biome, the semi-arid climate associated with an inadequate soil management has increased the degradation and loss of productive potential of the soil. In this context, the study of soil fauna, including springtails, becomes an important indicator of soil quality. This study aimed to evaluate the fauna of Collembola in an area of Caatinga of Rio Grande do Norte State and the influence of biotic and abiotic factors, such as soil, vegetation and climate characteristics, on the structure of the taxocenosis. The environmental variables which were used were the following ones: granulometry (represented by the proportion of sand), quantity of organic matter and soil pH, richness, density and aerial biomass of the vegetal structure, and necromass. We used pitfall traps intending to collect specimens of the epiedaphic fauna of Collembola in 30 points located on Cauaçu Farm, João Câmara, RN, in July (rainy season) and November (dry season) 2011. We collected 5513 individuals of 15 species distributed in 13 genera and 9 families of Collembola. Five of the recorded species are new to science, confirming the expected high degree of endemism for Caatinga biome, and the highest abundance was recorded in the rainy season, which suggests Collembola sensitivity to low humidity. Four species were more abundant in the dry season, all of them belonged to the Order Entomobryomorpha. Results of statistical analyzes suggest that plant species richness, aerial biomass of vegetal structure, proportion of sand in the soil, pH and humidity are the main influences to the abundance of Collembola in the region studied

Estudo teórico-bioclimático da potencialidade de desenvolvimento do Aedes aegypti no estado do Rio Grande do Norte

In the current climate of global public health there is the emergence of urban dengue, a disease regarded as acute infectious fever. The disease annually, has affected millions of people worldwide, mostly in the range of the intertropical globe. The disease's main vector in urban areas, the Aedes aegypti mosquito. Recent studies indicate that the distribution of the insect vector of dengue in the geographical area is directly tied to the behavior of environmental restrictions that area, especially among those, the air temperature and relative humidity. From that context, the work aims to estimate and spatializing, monthly, for each municipality in the state of Rio Grande do Norte, the potential of biophysical conditions conducive to the development of Aedes aegypti. Yet, made use of the following methodology: collection of epidemiological data and climatological, Normal climatological, descriptive statistics (measures of central tendency and scatter), uniform distribution, estimation geostatistics and sufer program, version 8.0. The results flagged for a behavior very heterogeneous, both in space and in time, in the case of the potential of biophysical conditions conducive to the development of Aedes aegypti in the state of Rio Grande do Norte. Still, he noted that there is a tendency for lifting the potential of development for the entire state, from the month of January, ending in the month of April mainly in central and western portions of the state. By contrast, there is the permanence of increased potential for development in the eastern portion of the state. The latter record maximum potential in the month of July, resulting probability of greater than 70% have been favorable conditions for the development of Aedes aegypti in that area. In the period between the months of August to December, it is small potential for development of Aedes aegypti in all parts of the state

Festa na escola e a autopoiese do lazer

This study shows the problem of school party and its relations with the perspective of leisure autopoiesis in the lives of students living in student housing. It has aimed to describe and interpret the most meaningful leisure experiences in daily life of a student housing and the ludopoietic processes for the humanescent self-education. From the theoretical assumptions supporting the development of this research have highlighted: Education by Freire (1996); Embodiment by Pierrakos (1990); Leisure by Dumazedier (1999); Party by Duvignaud (1983), Playful by Schiller (2002), Working by Freinet (1998), Autopoiesis by Maturana and Varela (2001), belonging to each day by Certeau (1994). A qualitative study adopts the principles of existential action research, in an ethnofenomenological perspective. As a methodology, we use the metaphor of sowing covering the planting, flowering, harvest and new planting. The scenario was to sow the Escola Agrícola de Jundiaí - RN. Twenty-five students residing in the school participated in research from 2007 to 2008, which involved more actively in the development of an extension project for the implementation of recreational and leisure experiences in that institution. The main instruments used for the construction of data collection were: participant observation, questionnaire, interview, game sand and photographs. The process of data analysis with the ethnofenomenological principles emphasized the following points: experientiality, indexicality, reflexivity, self-organizability, adoptability, archetypal and humanescenciality. New meanings of ludopoietic flowering of seed "party school" were revealed, and you can see the emergence of autopoietic leisure as a big green tree, able to sprout in soil properly fertilized to produce wonderful fruit of joie de vivre

Vivências ludopoiéticas no jogo de areia: a tatilidade na autoformação humanescente

This study presents the ludopoietic experiences in Sandplay and the expression of tactility in humanescente self-training of future teachers of geography. The overall objective was to analyze and interpret as the tactility in the ludopoietic experiences with Sandplay facilitates the sentipensar and boosts the humanescent self-training. The qualitative research approach follows the principles of existential research-action into the etnofenomenologic perspective, that considers studies of the ethnography and the phenomenology with ethnomethodology. In this study we used the sedimentary rock called sandstone and your mineral grains as cognitive operator to stimulate the discussions of the ludopoietic experiences in Sandplay. The members of research were students of the Geography degree of IFRN. To achieve the research objectives were organized experiential meetings and virtual meetings. The ludopoietic experiences in Sandplay revealed the impact of tactility to humanescente self-training, indicating the importance of touch for apprehend and experience the world with beauty, joy and tenderness. These experiences showed the ludopoietic system properties, the threads of embodiment and the meaning of the sentipensar of tactility as a phenomenon that drives the humanescent self-training, evidenced by etnofenomenologie. Data were obtained through Sandplay, sensitive listening, experiential diary, photographic and movie records. In the process of data analysis were revealed the of etnofenomenological principles of experientiality indiciality, reflexivity, self-organizability, filiability, archetypality and humanescencialidade. Through the tactility, the Sandplay favors the awareness of the condition of being, takes life stories, providing the construction of knowledge in a meaningful and contextual way

A ousadia como horizonte: religando vida e ideias na formação em enfermagem

A proposal of formation in health/nursing built on classic science, on reducing thought and flexnerian paradigm is insufficient to comprehend and intervening with an amplified way on health needs of population, given that it is produced by fragmentation of knowledge, rationalization of thought, mechanizing and biological attitudes. It is necessary that formation in health/nursing allows the construction of effectiveness of principles and guidelines of Unique System of Health (Sistema Único de Saúde - SUS). In this context of emergency of a complex formation in health/nursing, life trajectories and formation of the nurses: Abigail Moura, Francisca Valda and Raimunda Germano are examples of transgressor and successful experiences which allow inquietude, changing and transforming formation patterns and self-formation. The present study is built from the comprehension of method as strategy , defended by Morin and complexity sciences. Has as objects building biographies of formation of these three nurses who express a formation model more totalizing and humanitarian, analyzing and discussing starting from the three biographic fragments guiding principles for the current process of formation in health/nursing. From the biographies, the courage and humbleness emerge as landmarking principles of their experiences. Humbleness neither as self-depreciation nor humiliation but as consciousness of our uncompleted and unfinished essence, acceptance of boundaries and potential and reduction of intellectual vanity. Courage, for its part, is the human pulsing, uncertain for nature, which brings us to act, to face and persevere on moments of fear and difficulties. A formation in health and nursing based on courage and humbleness allows the subjects to be taken away from indifference, arrogance, inertia, pragmatism: bets on ethic and political subjects capable of minimizing unequal, inhumane and excluding processes. Na intellectual and Professional attitude which politizes the thought and science is what must be expected from a complex formation in health field, in latu mode on nursing, in particular

Evolução da paisagem do baixo curso do rio de Piranhas-Assu (1988-2024): uso de autômatos celulares em modelo dinâmico espacial para simulação de cenários futuros

The lower course of Piranhas-Assu river, located in the north coast of Rio Grande do Norte, Brazil, arouses a keen interest as a study field, once it concentrates, besides petroleum and gas exploration, activities related to shrimp culture, salt and horticulture, factors that also deserve special attention. Thus, the awareness of the study field environmental stage demands studies from researchers and discernment from society, as a way of understanding the inter-relation between environment and men. Therefore, this work attempts at understanding and studying the dynamics of land use in the lower course of Piranhas-Assu river, through a multitemporal analysis of present and past, accomplishing future projections through simulation models. The work is divided in stages that include the research, analysis, interpretation of results, and the generation of simulation models, to analyze the landscape tendencies, making possible to identify indicators which cause such changes in the lower course of the river. From Geographical Database, the necessary exploratory analyses were accomplished to the following items: land use evolution, natural and environmental vulnerability, multiple geodiversity indexes, and preparation of the data to be used in the simulation model. Later, the construction of the landscape simulation model was conducted. Sequentially, simulations of future sceneries were accomplished through the execution of the model in a specific software environment. Last, the analyses of landscape tendencies in the study field were carried out. The lower course of Piranhas-Assu River didn't show any intense dynamics in landscape changing, once in the period taken into account (from 1988 to 2004) class stability proved to be superior to its transformations. Activities related to agriculture and livestock are the ones that influence, mostly, the landscape dynamics. The production of sea shrimp and petroleum also infers in the landscape, although in smaller proportion. INCRA s public policies excessively determined the dynamics of the landscape in the lower course of Piranhas-Assu River, RN. In respect to its natural vulnerability, the lower course of Piranhas-Assu River, RN, features more vulnerable than stable areas. The landscape simulation, in the first taken period (2004-2009), indicated considerable increases and decreases of antropic activities, if compared to its sequent periods (2009-2014, 2014-2019 and 2019-2024). The simulation, in a wider analysis, showed that the determining factors for the space mobility of antropic activities, in the focused area, are related to the pre-existence of communities with agricultural capability and to the existence of access routes and drainage. Considering the area that features fixed and mobile dunes, located in Porto do Mangue district, we recommend its conversion into a conservation area

Da compreensão novas viagens de Gulliver

Ayant comme opérateur cognitif le livre Les Voyages de Gulliver, de Jonathan Swift, la thése, écrite au format d'un journal de bord, suit dévoilant des indices pour une archéologie de la compréhension, au-delà de problématiser les interconexions entre communication et compréhension à l'actuel procés de planétarism. En suite, réalise quelques essais qui problématisent l'éthique, la science, et la condition humaine, sous l'inspiration du Parlément des Choses, suggéreé par Bruno Latour, où sont présents, symétriquement, les sciences, les scientists, les politiques, les natures, les cultures, et les sociétés. Pour une telle aventure, sont agencées des ideas de penseurs de diverses domaines de la connaissance, comme Edgar Morin, Henri Atlan, Hans-Georg Gadamer, Isabelle Stengers, David Bohm, Maria da Conceição de Almeida, Cremilda Medina, María Zambrano, Michel Serres, Boris Cyrulnik, dentre autres. Lettres de musique, registres littéraires et cinématographiques servent de points d'appuy pour la contextualization du récit de ce voyage qui ne comporte pas seulement la compréhension de la compléxité de l'être-humain, mais aussi, la compréhension des conditions dans lequelles sont forgées les mentalités et pratiques les actions. Ainsi, toule compréhension est un voyage sans fin: arrive à quelques ports, se ré-approvisionne et part à nouveau. Toute compréhension est ponctuelle, parcielle, provisoire, lacunaire et inachevée.

A fábrica de professores e a padronização do conhecimento

This paper concern the general subject of teacher career construction, since the period of the initial formation in the teaching course of pedagogy crossing the first effectives experiences of professional performance, until the reflections about the results of the continuous formation propositions. The specifics subject is the formative quotidian in the teacher s life beyond of the traditional stereotypes about individuals and institutions bring up for discussion a micro sociological approach about the professionals uncertainty and the personal hopes, the teacher displeasures and the pedagogical satisfactions. The epistemological reflection about the different formatives experiences, taking as example the Programa de Formação de Alfabetizadores PROFA (Alphabetizers Formation Program) developed by the Secretaria Municipal de Educação of Natal City, consider the ambiguous tension between the knowledge that the teachers acquire in their formation and the concrete teachers practical since those experiences. The study methodology is based in the qualitative comprehensive research, sustained by observations, impressive reflective accounts, and also in the theoretic analyses with contemporary references to the critical pedagogical through and education sociology. I used the autobiographic reflective account by the writer-researcher in her owner academic and professional way. I propose an image of a teacher s factory in such a way for its conformist aspects to the continuity stands as much the internal contradictions of the system. Gears, pieces and manual instructions are the educational components of this factory as ideological, institutional and technical structures to aim at to limit the critics and the changes. However the teachers thinking and acting with their owner creativity to adapted uncontexted professional knowledge s to their pedagogical lives. Under those analogies I propose the problem of this research the teacher s formation and theirs pedagogical practices- and also examine briefly its theoretic-philosophical and methodological basis. From the analysis and interpretation of my owner experiential life as teacher s educator I put the necessity of re-thinking the teacher s formation in terms to rebound more meaningfully in their pedagogical actuation. I believe an important part of the teacher s formation process is the personal wish to learn more about the office, explicitly connected to human convictions and values such as to a positive professional identity. Thus, the teacher able to reflect about your owner educator life can find the best way to help the students to think critically about their culture and history, valorizing creative exits by themselves to face the conformist social stands connected with school education

Desenvolvimento de uma rota química alternativa de síntese de SrCo0,8Fe0,2O3- e LaNi0,3Co0,7O3- para aplicação na reação de oxidação do CO

This thesis focuses on the coprecipitation synthesis method for preparation of ceramic materials with perovskite structure, their characterization and application as catalytic material in the reaction of converting CO to CO2 developing a methodological alternative route of synthesis from the middle via oxalate coprecipitation material SrCo0,8Fe0,2O3-d. In order to check the influence of this method, it was also synthesized using a combined citrate - EDTA complexing method. The material was characterized by: X-ray diffraction (XRD), Rietveld refinement method, thermogravimetry and differential thermo analysis (TG / DTA), scanning (SEM) and transmission (TEM) electron microscopy, particle size distribution and surface analysis method BET. Both methods led to post-phase synthesis, with pH as a relevant parameter. The synthesis based on the method via oxalate coprecipitation among particles led to the crystalline phase as those obtained using a combined citrate - EDTA complexing method under the same conditions of heat treatment. The nature of the reagent used via oxalate coprecipitation method produced a material with approximately 80 % lower than the average size of crystallites. Moreover, the via oxalate coprecipitation method precursors obtained in the solid state at low temperature (~ 26 oC), shorter synthesis, greater thermal stability and a higher yield of around 90-95 %, maintaining the same order of magnitude the crystallite size that the combined citrate - EDTA complexing method. For purposes of comparing the catalytic properties of the material was also synthesized by the using a combined citrate - EDTA complexing method. The evaluation of catalytic materials SrCo0,8Fe0,2O3-d LaNi0,3Co0,7O3-d was accompanied on the oxidation of CO to CO2 using a stainless steel tubular reactor in the temperature range of 75-300 oC. The conversion CO gas was evaluated in both materials on the results shaved that the firm conversion was loves for the material LaNi0,3Co0,7O3-d

Obtenção e caracterização de filmes SnO2 depositados em vidro borosilicato por silk-screen modificado: SnCl2.2H2O como precursor

O presente trabalho tem como objetivo investigar as características de filmes de SnO2 depositados em substrato de vidro borosilicato por um processo de silk-screen modificado para obtenção de espessura fina compatível com a aplicação em células solares policristalinas de baixo custo. O filme de SnO2 é um dos mais apropriados para obtenção de vidro TCO (transparent conductive oxide) para uso em células solares devido a sua baixa resistividade elétrica e alta transmitância, sendo quimicamente inerte, mecanicamente duro e tem resistência a altas temperaturas, o que facilita então a calcinação das amostras entre 500º C a 550º C. Os filmes foram obtidos a partir de uma solução precursora básica, preparada pela dissolução de SnCl2.2H2O em Etanol (99,5 %). Foi realizado um planejamento fatorial 2(3-1) para analisar a influência dos parâmetros concentração da solução precursora (CETN), temperatura de calcinação (TC) e taxa de aquecimento (tX) na calcinação, sendo a concentração CETN o parâmetro que apresentou maior efeito sobre os parâmetros de respostas investigados: espessura do filme (ω), resistividade de superfície (ρ) e a transmitância relativa (θ). Foi possível obter com a metodologia utilizada, filmes com espessuras da ordem de 1 Nm com resistividade de superfície de 10 / e transmitância relativa entre 70 e 80 %.

Caracterização Morfodinâmica e Sedimentologia da Plataforma Continental Rasa na APA Estadual dos Recifes de Corais - RN

This study had to aimed to characterize the sediments of shallow continental shelf and realize the mapping of features visible for satellite images by using remote sensing techniques, digital image processing and analysis of bathymetry between Maxaranguape and Touros - RN. The study s area is located in the continental shallow shelf of Rio Grande do Norte, Brazil, and is part of the Environmental Protection Area (APA) of Coral Reefs. A total of 1186 sediment samples were collected using a dredge type van veen and positioning of the vessel was made out with the aid of a Garmin 520s. The samples were treated In the laboratory to analyze particle size of the sediment, concentration of calcium carbonate and biogenic composition. The digital images from the Landsat-5 TM were used to mapping of features. This stage was used the band 1 (0,45-1,52 μm) where the image were georeferenced, and then adjusting the histogram, giving a better view of feature bottom and contacts between different types of bottom. The results obtained from analysis of the sediment showed that the sediments of the continental shelf east of RN have a dominance of carbonate facies and a sand-gravelly bottom because the region is dominated by biogenic sediments, that are made mainly of calcareous algae. The bedform types identified and morphological features found were validated by bathymetric data and sediment samples examined. From the results obtained a division for the shelf under study is suggested, these regions being subdivided, in well characterized: (1) Turbid Zone, (2) Coral Patch Reefs Zone, (3) Mixed Sediments Carbonates Zone, ( 4) Algae Fouling Zone, (5) Alignment Rocky Zone, (6) Sand Waves Field (7) Deposit siliciclastic sands

Organização espacial e processo saúde-doença no bairro Guarapes, Natal/RN

La santé et la maladie sont des objets de préoccupation dans la société. Tout au long de l'histoire de l'humanité, ils ont été traités sous différents yeux. La géographie est une façon de comprendre les processus liés à des questions de santé et de maladie, de façon privilégiée dans le but d'être une science concernées par la zone géographique où cela implique non seulement une structure de la matière, mais les personnes et les flux découlant de la relation est établie Entre la société et la nature. Un lien est établi entre l'organisation spatiale de la santé-maladie est au c ur de ce travail, avec la coupe Guarapes espace du quartier, situé dans l'ouest de la Région administrative de Natal (plus bolsão pauvreté de la ville) pour la période correspondante de la 1990 par 2004 (jalon important pour le bien et la dynamique des populations de la zone d'étude) et de réduire le temps de la recherche. Au cours de l'analyse procède à l'étude des formes de production et d'organisation de l'espace vécu. Depuis comprendre le quotidien des personnes souffrant d'un réseau de relations, motivés par les besoins et la solidarité qui génèrent des formes et des contenus qui façonnent l'aire géographique. Sur la base de revue de la littérature, la recherche empirique à travers la réalisation des feuilles de route des entretiens avec le représentant des gens du quartier (résidents, des dirigeants communautaires, des coordonnateurs pédagogiques, des infirmières et des agents de santé de la PSF). Outre les visites effectuées à l'Agence de régulation des services d'assainissement de la municipalité de Noël - ARSBAN, le Secrétariat spécial pour l'Environnement et Urbanisme - SEMURB, secrétaire du Travail et de la protection sociale SEMTAS, Secrétariat municipal de la santé - SMS. Sur la base de l'espace vécu voir que les éléments du quotidien local exercer une forte influence sur la santé et La maladie de la population étudiée, avec un accent sur les problèmes découlant de chômage, sous-emploi, l'insécurité et un manque d'assiduité de certains responsables de l'USF - Guarapes. La production et l'organisation de la région convergent à l'apparition de maisons, les rues et les petits commerces non équipés de l'infrastructure de base dédiée à la prise en charge des personnes favorables à l'occupation désordonnée et non planifiée pour plusieurs zones du district, ainsi que l'apparition De vecteurs transmetteurs de maladies
