Avaliação físico-química e funcional da algaroba prosopis juliflora proveniente da mesorregião agreste do Rio Grande do Norte

Algaroba (Prosopis juliflora) is a typical legume from arid and semi arid regions, which is composed by sugar-rich pods and high protein seeds. Phenolic compounds are secondary metabolites recognized as potent bioactive compounds, found in several vegetables.Therefore, the objective of this work is to characterize the algaroba flour in terms of its physicalchemical composition, total phenolic content, antioxidant activity by DPPH and ABTS methods, a-amylase and a-glycosidase inhibition, as well as to analyze its organic compounds by high performance liquid chromatography (HPLC). Three experimental groups were investigated (seeds, seeds and pod together and only pod), which were prepared by oven drying and posterior grinding. Water and ethanol extracts (70, 80, 100% v/v) were prepared and used for functional studies. Organic compounds were detected by using HPLC equipment coupled to mass spectrometer. Results show important physical-chemical differences among the experimental groups, seeds, seeds and pod together and only pod. The algarroba seed flour is high in protein (49.49%) and fat (3.10%), while the pod flour is especially rich in sugar (60.3% to 67.9%). Algaroba phenolics are concentrated in pod flour, mainly in water extracts (1.30 mg GAEQ/100g sample). All seed extracts showed high DPPH activity and maximum antioxidant activity was registered for ethanol 80% extracts (19.81 μM Trolox/g sample). The ABTS activity ranged from 9.73 to 12.74 μM Trolox/g sample. Nearly all the extracts were able to inhibit α-amylase activity mildly (30.50% to 48.80%), while the maximum α-glycosidase inhibition was observed for pod water extracts (81.03%). Algaroba water extracts proven to be especially rich in organic compounds, observed by the high number of chromatographic peaks. Results demonstrate that algaroba is a potential candidate for further investigations concerning its possible functional applications

Investigação dos processos hidrossedimentológicos em parcela experimental no semi-árido potiguar

In northeastern semiarid, seasonality on precipitation temporal distribution, high intensity storm events and inadequate management of native vegetation can promote soil erosion. Vegetation removal causes soil surface exposure, reduces soil water storage capacity and can be the source degradation processes. In this context, this approach aims to analyze water and soil erosion processes on a 250 m2 undisturbed experimental plot with native vegetation, slope 2.5% by using 2006 and 2007 monitoring data. The site was instrumented to monitor rainfall, overland flow runoff and erosion by using a 5 m³ tank downstream the plot. Soil erosion monitoring was made by transported sediment and organic matter collection after each event. Field infiltration experiments were made at 16 points randomly distributed within the plot area by using a constant head infiltrometer during drought and rainy seasons, respectively. Infiltration data revealed high spatial and temporal variability. It was observed that during the beginning of the rainy period, 77% of the events showed runoff coefficient less than 0.05. As the rainy season began, soil water increase produced annual species germination. High intensity storms resulted in runoff coefficients varying between 0.33 and 0.42. Once the annual species was established, it was observed that approximately 39% of the events produced no runoff, which reflects an increase on soil water retention capacity caused by the vegetation. A gradual runoff reduction during the rainy season emphasizes the effect of vegetative density increase. Soil erosion observed data allowed to fit an empirical relationship involving soil loss and precipitation height, which was used to analyze the plot installation impact on soil erosion. Observed soil loss in 2006 and 2007 was 230 Kg/ha and 54 Kg/ha, respectively

Aplicação e análise de metodologia de deterioração ambiental em micro-bacia do seridó potiguar

In the contemporary world to the deterioration of semi-arid areas of the planet has been the focus of media attention and the scientific community. Brazil has a semiarid, considered the most problematic of the world, either by pressure from physical factors, whether as a result of misguided public policies, has over time been suffering from the consequences of a deterioration that expands over the years. Methodologies, that amidst the problems of semi-arid, come against the deteriorating local, have a good chance to be reapplied in other contexts around the world. This research, based on methodological model for analyzing environmental deterioration, introduced and examined the applicability of the methodology in the semi-arid region of Rio Grande do Norte - Brazil. Although the results provide guidelines for the introduction of underground dams, the application of the methodology was ineffective, given the high rates of forest cover that gave low values for the physical diagnosis conservationist

Análise da precipitação no semi-árido potiguar

The semiarid rainfall regime is northeastern Brazil is highly variable. Climate processes associated with rainfall are complex and their effects may represent extreme situations of drought or floods, which can have adverse effects on society and the environment. The regional economy has a significant agricultural component, which is strongly influenced by weather conditions. Maximum precipitation analysis is traditionally performed using the intensity-duration-frequency (IDF) probabilistic approach. Results from such analysis are typically used in engineering projects involving hydraulic structures such as drainage network systems and road structures. On the other hand, precipitation data analysis may require the adoption of some kind of event identification criteria. The minimum inter-event duration (IMEE) is one of the most used criteria. This study aims to analyze the effect of the IMEE on the obtained rain event properties. For this purpose, a nine-year precipitation time series (2002- 2011) was used. This data was obtained from an automatic raingauge station, installed in an environmentally protected area, Ecological Seridó Station. The results showed that adopted IMEE values has an important effect on the number of events, duration, event height, mean rainfall rate and mean inter-event duration. Furthermore, a higher occurrence of extreme events was observed for small IMEE values. Most events showed average rainfall intensity higher than 2 mm.h-1 regardless of IMEE. The storm coefficient of advance was, in most cases, within the first quartile of the event, regardless of the IMEE value. Time series analysis using partial time series made it possible to adjust the IDF equations to local characteristics

Produção em revista : Representação do moderno e do regional na experiência potiguar anos 1920

This work brings some reading about a few Norte-rio-grandenses writers collaborations published in literary papers which circulated during the third decade of the twentieth century in Brazil, in a way of enlarging the understanding of how the cultural debate was carried out in the years of the definition of the Brazilian Modernism, based on the relationships between literature and culture. Under the genres of prose and poetry, the selected textual collaborations for analysis have brought the traces of a small group of articulated authors in the Brazilian cultural scenery from the 1920 s, concerning the issues of the modern (linked to the modernist renovation) and the regional (under the aspects of the tradition). The set of the analyzed collaborations is representative of a modern-regional cultural practice marked by a tendency either local or cosmopolitan, thus, sharing a large dimension of the formation of the modern literary tradition, marked by different kinds of practices which give form to the project of a collective national awareness. The characterization of the existence of an intellectual field with big links, however with its own characteristics and a certain autonomy, which also gets integrated to the cultural debate of the so-called modernist years through the literary vehicles, gives to these intellectual people a co-participation in the renewing movement in the formation context of the brazilian cultural modernity of the early twentieth century

Coerção e ruptura estilísticas na poesia potiguar: a construção do ethos inventivo do poeta Jorge Fernandes

Within the poetic scenario of Rio Grande do Norte the publication of Livro de Poemas de Jorge Fernandes, in 2007, marks, in the imagery of the Potiguar community of poetry readers, producers and critics, the beginning of the social circulation of an inventive ethos associated with the poet Jorge Fernandes de Oliveira (1887-1953). Regarding the event mentioned earlier as a point of reference, this research investigates the construction of such ethos based on the counterpoint between the poet s individual stylistic choices and the stylistic options that prevailed in the lyric production of the Twenties in the 20th Century. The corpus comprises poetic texts (by the poet under discussion and by other poets who were, then, regarded as icons of the poetry of Rio Grande do Norte) and texts representative of local literary criticism (produced both during the Twenties and in other decades of the last century). Support to this analysis is grounded in Mikhail Bakhtin s theory of the utterance (mainly regarding style) and in Dominique Maingueneau s theory of the utterance (mainly regarding ethos). During the course of this investigation, the research has outlined an inventory of the prevailing individual stylistic choices of Jorge Fernandes de Oliveira and the reasons why such choices point out towards the inventive ethos associated with the poet.

O sertão potiguar comunica: midiatização e práticas sociais. Ou como a recepção da pauta política se desdobra em práticas sociais em Pau dos Ferros

This dissertation is the result of the development of a two-year research entitled POTIGUAR ACROSS THE COMMUNICATION: MEDIATIZATION AND SOCIAL PRACTICES. Or as the reception of the political agenda unfolds in social practices of the Pau dos Ferros, showwing Pau dos Ferros as a provincial oestano of Rio Grande do Norte, now living a meaningful set of social transformations, which interact with practices media that have just mediatized new public policies in the area of Technical Education and Higher Education. Thus, with the introduction and expansion of state and federal public policy of democratization of Technical and Higher Education in the period 2002 to 2010, the phenomenon of migration of students from elementary and high school, before existing in the region has changed significantly in that Pau dos Ferros polo is made. The concentration of the media city in the hands of politicians, in their favor, and the emergence of new midiatizações are contributed to the formation of this (non-migration) and other social practices, reinventing and rearranging the schedule of the ideas and concepts about the educational practices. Our goal is to observe the relationship of interaction between media, politics and education and examine how young students are realizing this interaction. Under the prospects of receiving the light of Cultural Studies, strolling our research primarily on the technique of focus group data collection

Entre a ausência declarada e a presença reclamada: a identidade potiguar em questão

How do the identities of a people build themselves? How do the geographic clippings influence the representations of some social groups, when they define themselves or when they are defined, for example, as people from Pernambuco, Rio Grande do Sul, Paraíba, Rio de Janeiro, Ceará, Bahia? What symbolic elements, contests and benefits are involved in these processes of identity construction? By taking the discussions about potiguar people as the theme of this research, we intend to discuss about the displacements, the impasses in their representations that usually represent him as a being who he is not, constantly seduced by the enchantments of the other, by the values that come from outside. Thus, from the Rio Grande do Norte space, we investigated, in various contexts, since the last three decades of the nineteenth century to the current days, how the space identities have been used as strategy, by various characters, in attempt to build and/or to define representations that characterize and single potiguares out, in the face of other beings of the nation

Avaliação da estratégia saúde da família na capital potiguar

This research aimed to evaluate the Family Health Strategy (FHS) in Natal, Rio Grande do Norte, through its managers, professionals and users, having as its support the Theory of Belief and the Cognitive-Behavioral Theory. This is a multimethod research and is divided into three sub-studies. In the first study, nine managers answered to a semi-structured interview, to verify the knowledge and beliefs on SUS; the quantitative data were analyzed with descriptive statistics with the aid of SPSS software and the qualitative data were submitted to lexical analysis with support of ALCESTE software. In the second study, we have a descriptive correlational research in which the antecedent variables are related to working conditions in the family health units (FHUs) and to the professionals‟ profile; the corresponding variables refer to the evaluations of the FHS; a stratified probabilistic sample with 475 professionals, who answered to two scales, both consisting of three factors: Physical infrastructure, Material resources, and Treatment effectiveness, and data were analyzed using descriptive, bivariate and multivariate statistics, with the aid of SPSS. The third study is a descriptive correlational research in which the antecedent variables refer to the treatment in the FHUs and to the users‟ profile, and the corresponding variables refer to the evaluations of the FHS, with a stratified non-probabilistic sample with 390 users, who contributed to the construction of a new scale with a factor, effectiveness in treatment, analyzed through descriptive, bivariate and multivariate statistics, with the aid of SPSS. The results showed problems which start from management, under the shape of admission due to political indication and lack of knowledge on SUS and the FHS; they pass through the low tenure of professionals and insufficient professional; and they end up spreading all over the analyzed items: infrastructure of FHUs, material resources, professionals‟ training, accessibility and referral system. One concludes that, despite following an ideal model, the FHS is in need of changes with regard to the barriers to its operational reality

Gênero, trabalho e saúde mental entre trabalhadoras rurais assentadas na região do Mato Grande Potiguar

The lack of studies aimed at the mental health of the rural population, the social, economic, familial and emotional impact that mental disorders produce and the vulnerability that women have in this context, lead us to believe in the need to investigate the mental health demands of female rural workers, in order to subsidize the development of more effective and culturally sensitive public health programs and policies that take into account the specificities of this population. The present study aims to investigate the prevalence of common mental disorders (CMD) and the possible factors associated with the emergence of such disorders among women living in a rural settlement in Rio Grande do Norte. This survey has a quantitative and qualitative character with an ethnographic approach. As methodological strategies, we made use of an adapted version of the socio-demographic and environmental questionnaire prepared by The Department of Geology/UFRN s Strategic Analysis Laboratory to evaluate the quality of life of the families from the rural settlement and the mental health screening test Self-Reporting Questionnaire (SRQ-20) to identify the prevalence of CMD in adult women from the community. Complementing the role of methodological tools, we use the participant observation and semi-structured interviews with women who presented positive hypothesis of CMD attempting to comprehend the crossings that build the subjective experience of being a woman in this context. The results point to the high prevalence of CMD (43.6%) and suggest the link between poverty, lack of social support, unequal gender relations and the occurrence of CMD. We also verified that the settled women do not access the health network to address issues relating to mental health and that the only recourse of care offered by primary health care is the prescription of anxiolytic medication. In this context, the religiosity and the work are the most important strategies for mental health support among women

Frequencia de enteroparasitoses em usuários do servico público de saúde na mesorregião do oeste potiguar

Em um mundo de grande pobreza, as enteroparasitoses podem exercer um papel importante no que se refere às desigualdades sociais, pois estas mazelas se apresentam, em sua grande maioria, na população mais carente. Estas mesmas doenças causam inúmeros casos de faltas ao trabalho e a escola, gerando preocupação dos profissionais de saúde, já que estes parasitas podem agravar ou desencadear quadros de anemia e desnutrição. O trabalho procurou pesquisar a prevalência de enteroparasitas na Mesorregião do Oeste Potiguar, em uma população que utiliza o sistema público de saúde, buscando associar as variáveis, como: sexo, faixa etária, período sazonal, renda familiar e número de parasitas. Foi utilizada a técnica de Hofmann (sedimentação espontânea) e o material fecal foi analisado pelos funcionários do Laboratório Central de Mossoró e Pau dos Ferros. Foi realizado no período de 02 de março de 2010 a 28 de março de 2011 o exame coprológico em 16.246 pessoas no laboratório Central de Mossoró (Lacen) e Pau dos Ferros, RN. A análise dos exames mostrou que 69,23% dos infectados eram mulheres e 33,07% eram homens. A maior prevalência ocorreu com Endolimax nana (41,61%), seguido de Entamoeba coli (18,46%) e Giardia lamblia (18,59%) em 3.407 parasitas encontrados. Dentre os exames realizados, o Endolimax nana foi o mais prevalente entre os organismos encontrados. A diferença nos resultados entre mulheres e homens pode determinar um foco domiciliar, pelo descaso do poder público com as políticas de saneamento básico e falta de higiene da população, e pela atividade das mesmas com trabalhos domésticos

Dinâmica da paisagem na Microbacia do Riacho Cajazeiras no semiárido potiguar

The semi-arid Northeast region are coming through changes since its formation causing changes in the landscape and increased degradation. The economic dynamics which was established at the Potiguar semiarid had for a long time settled in livestock, subsistence agriculture and cotton, however, these economies decline from the year 1970. Thus, the Potiguar spaces are undergoing by a process of space reordering marked by the growth of agricultural activities and the process of urbanization. In the Potiguar western region these changes weaken significantly transform the landscape. In these areas, the process of urbanization and agricultural activities have caused changes in the hinterland landscape changing the natural dynamics of the caatinga biome that has been subject to negative interference with the indiscriminate removal of vegetation. In this case, the specific study area of the watershed of Cajazeiras Creek located in the cities of Pau dos Ferros, Água Nova, Encanto and Rafael Fernandes, changes in the landscape has led to degradation and environmental fragility. From this perspective, the research objective is to assess the dynamics of the landscape of the watershed of Cajazeiras Creek, semiarid region of the state of Rio Grande do Norte, identifying the degrading factors, the most degraded areas and/or susceptible to degradation and environmental fragility. The research investigated the phenomena of light geosystems theory that emphasizes the integration of elements in shaping the landscape. During this reporting period, it was carried out exploratory and bibliographical research, and geoprocessing techniques to assess the social and environmental conditions of the researched area and its environmental fragility. To do so, first, it was made an multitemporal analisis on the basis of the years 1984, 1996 and 2009 demonstrating that the dynamics of use and land cover in the watershed of Cajazeiras Creek showed a significant change in the landscape, especially in the caatinga vegetation. This has been recovering in various areas of the watershed, especially in its upper course in the mountains of Bom Sera, in Encanto city. The analysis showed the need to develop policies and programs for the maintenance, restoration and preservation of the caatinga vegetation of the river network and of water bodies. In addition, it was identified the most degraded areas of the watershed, environmental fragility and potential emerging that take into account the landscape components such as climate, topography, geology, pedology, geomorphology and the use and occupation of the soil in an integrated manner. The results show that the landscape of the watershed has medium and high environmental fragility throughout its area, especially on the banks of the river network provided by the use and occupation of the soil in an inadequate way with the environmental conditions of the watershed
