IMPACT OF CLIMATE CHANGE ON THE POTENTIAL DISTRIBUTION OF NATIVE AND INVASIVE GRASSES IN THE CERRADO

Biological invasion, mainly by African grasses, is one of the main threats to the Cerrado's biodiversity. The objective of this study was to elucidate the distribution patterns of the exotic grass Melinis minutiflora and the native grass Trichanthecium cyanescens, in order to verify the areas of potential occurrence of these species and, thus, to infer if their potential distribution will be affected by climate changes. Species occurrence data and ten uncorrelated climatic variables referring to the forecasts for the current period and future forecasts (2050 and 2070) were used for the analysis of the modeling. The models indicated the existence of environmental suitability, with AUCs above 0.8 (good) being observed in M. minutiflora and above 0.9 (excellent) in T. cyanescens. It is concluded that climate change may have negative impacts on the geographic distribution of these species, reducing the area of environmental suitability for them. In addition, the species studied have similar areas of potential distribution and regularly overlap, which can make M. minutiflora a threat to the conservation of T. cyanences, due to the invasion potential of the first

Daily rainfall disaggregation for Tocantins State, Brazil

In order to design effective Brazilian hydraulic structures, it is necessary to obtain data relating to short-duration intense rainfall from historical series of daily rainfall. This recurring need can be fulfilled by rainfall disaggregation methodology. The objective of this study was to determine the intense rainfall disaggregation constants for the State of Tocantins and to compare these constants with those obtained for other regions of Brazil. For the modeling of the frequency of intense rainfall of different durations of less than 24 hours, the Gumbel probability distribution (GPD) was employed using rainfall series from 10 locations in Tocantins state. The results showed that the GPD was adequate by the Kolmogorov-Smirnov and Chi-square tests. The disaggregation constants presented low variability values for different return periods (from 10 to 100 years); the values for Tocantins state are: h12h/h24h=0.93, h6h/h24h=0.86, h4h/h24h=0.82, h3h/h24h=0.78, h2h/h24h=0.72, h1h/h24h=0.61, h50min/h1h=0.92, h40min/h1h=0.83, h30min/h1h=0.68, h20min/h30min=0.76 e h10min/h30min=0.46. The comparison of the results with those from studies developed for other Brazilian regions showed variations of up to -62.30%, allowing us to conclude that the use of local constants is important in the process of rainfall disaggregation.Para o dimensionamento da estrutura hidráulicas do Brasil, é necessário a obtenção de dados de chuvas intensas de curta duração a partir de séries históricas de chuva diária. Esta situação recorrente pode ser atendida pela metodologia de desagregação de chuvas. Objetivou-se neste trabalho determinar constantes de desagregação de chuvas intensas para o Estado do Tocantins e proceder a comparação destas constantes com aquelas obtidas para outras regiões do Brasil. Para a modelagem da frequência das chuvas intensas de diferentes durações, foi empregada a distribuição de probabilidades Gumbel, tendo sido utilizadas séries pluviográficas de 10 localidades do estado do Tocantins. Os resultados mostraram que a distribuição de probabilidades Gumbel foi considerada adequada pelos testes Kolmogorov-Smirnov e Qui-quadrado. Observou-se que as constantes de desagregação apresentaram valores praticamente invariáveis para tempos de retorno entre 10 e 100 anos, tendo sido obtidas as seguintes constantes médias para o estado do Tocantins: h12h/h24h=0,93, h6h/h24h=0,86, h4h/h24h=0,82, h3h/h24h=0,78, h2h/h24h=0,72, h1h/h24h=0,61, h50min/h1h=0,92, h40min/h1h=0,83, h30min/h1h=0,68, h20min/h30min=0,76 e h10min/h30min=0,46. A comparação dos resultados com os de estudos desenvolvidos para outras regiões brasileiras mostrou variações de até -62,30%, permitindo se concluir que a utilização de constantes locais é importante no procedimento de desagregação de chuvas

Identification of Variables and Information Requirements for Implementation of Traceability in Egg Production

Brazil is the 3rd largest egg producer in the Americas and for production to be achieved, it must be organized to produce with quality and productivity. For all quality requirements to be met, guidance documents such as EMBRAPA and the Brazilian Poultry Union cover all stages of the production process, from the origin of the inputs to the later stages of production. In addition to these instructions, other legislation dealing with traceability is used to regulate production processes in food chains. In this context, the objective of this work is to confront the main national and international standards related to traceability to verify common requirements and that can compose a system of data collection. The work was divided into three stages and presented as a result the common requirements: sanitary management in the breeding and rearing phases, lineage, input control, poultry vaccination, poultry feeding, sanitary monitoring, egg collection information, eggs, and biosafety, product description, batch identification, date of shipment and data of the sending company and data of the company of destination, in addition to the information retrieval system

Treinamento físico melhora a saúde cardiovascular em mulheres no climatério

Cardiovascular diseases are the most important cause of death in both sexes in the Western world. Accordingly, the climacterium, is a women life phase in which the cardiovascular risk is much higher leading to an elevated morbi-mortality observed in this population. This fact may be justified, at least in part, by the current evidences that estrogen has a cardio protector function, and this hormone has been associated to the control of some risk factors such as obesity, hypertension and dislipidemia. However, many studies have indicated that the exercise training can be an important non-pharmacological approach in the reduction and/or attenuation of cardiovascular riskAs doenças cardiovasculares (DCV) constituem a mais importante causa de morte em ambos os sexos no mundo ocidental. Nesse sentido, o climatério é uma etapa no ciclo de vida das mulheres no qual o risco cardiovascular está muito aumentado favorecendo um incremento da morbi-mortalidade observada nesta população. Esse fato pode ser explicado, pelo menos em parte, pelas atuais evidências de que o estrogênio tem uma função cardioprotetora, e este hormônio tem sido associado ao controle de alguns fatores de risco como a obesidade, hipertensão arterial e a dislipidemia. Todavia, muitos estudos têm postulado que o treinamento físico pode ser uma importante abordagem não farmacológica na redução e/ou atenuação de fatores de risco cardiovascular em mulheres após a menopausa

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

Long-Lasting Efficacy of Radio Electric Asymmetric Conveyer Neuromodulation Treatment on Functional Dysmetria, an Adaptive Motor Behavior

BackgroundFluctuating asymmetry (FA) is widely defined as the deviation from perfect bilateral symmetry and is considered an epigenetic measure of environmental stress. Rinaldi and Fontani hypothesized that the FA morpho-functional changes originate from an adaptive motor behavior determined by functional alterations in the cerebellum and neural circuits, not caused by a lesion, but induced by environmental stress. They called this phenomenon functional dysmetria (FD). On this premise, they developed the radio electric asymmetric conveyer (REAC) technology, a neuromodulation technology aimed at optimizing the best neuro-psycho-motor strategies in relation to environmental interaction.AimsPrevious studies showed that specific REAC neuro postural optimization (NPO) treatment can induce stable FD recovery. This study aimed to verify the duration of the NPO effect in inducing the stable FD recovery over timeMaterials and methodsData were retrospectively collected from a population of 29,794 subjects who underwent a specific semiological FD assessment and received the NPO treatment, regardless of the pathology referred.ResultsThe analysis of the data collected by the various participants in the study led us to ascertain the disappearance of FD in 100% of the cases treated, with a stability of the result detected up to 18 years after the single administration of the REAC NPO treatment.ConclusionsThe REAC NPO neurobiological modulation treatment consisting of a single administration surprisingly maintains a very long efficacy in the correction of FD. This effect can be explained as the long-lasting capacity of the NPO treatment to induce greater functional efficiency of the brain dynamics as proven in previous studies

A aventura crítica da semiótica

A aventura crítica da semiótica percorre as principais teses sobre a semiótica e a comunicação conforme trabalhadas na primeira etapa da pesquisa Semiótica Crítica, denominada Por uma teoria das materialidades na comunicação. Nela, o Grupo de Pesquisa Semiótica e Culturas da Comunicação procurou discutir as potencialidades e limites de uma perspectiva comunicacional não somente fundamentada nos trabalhos fundadores da semiótica (Saussure, Peirce) e desenvolvida em seus modelos estruturalistas (como em Jakobson, Barthes, Hjelmslev e Lotman), mas também revisitada pelos textos que operaram uma desconstrução do estruturalismo pelo interior dos postulados deste próprio estruturalismo (Derrida, Kristeva, Deleuze, Guattari). O artigo apresenta esta proposta pelos modos como a pesquisa trabalhou com dez desconstruções ligadas a conceitos e problemas teóricos centrais ao debate das materialidades da comunicação: semiótica, comunicação, materialidades, presença, fenômeno, representâmen, meios, signo e significante, estrutura e sistema, sugerindo uma passagem das materialidades à imanência de uma comunicação micropolítica e póshumana.The critical adventure of semiotics courses through the main theses about semiotics and communication that have been discussed during the first stage of the research Critical Semiotics: Towards a theory of materialities in communication. In it, the Semiotics and Communication Cultures Research Group (GPESC) discussed the potentialities and limits of a communicational perspective not only based on the founding works of semiotic research (Saussure, Peirce) and developed in its structuralist models (Jakobson, Barthes, Hjelmslev, Lotman), but also revisited by ideas that deconstructed structuralism through the postulates of this very structuralism (Derrida, Kristeva, Deleuze, Guattari). The paper presents this suggestion by means of ten deconstructions related to concepts and theoretical problems which are key to the debate around the materialities of communication: semiotics, communication, materialities, presence, phenomenon, representamen, mediums, sign and significant, structure and system. In so doing, it suggests a move from materialities towards the immanence of a micropolitical and posthuman communication
