Avaliação quantitativa da dinâmica espaço-temporal da precipitação na região hidrográfica Tocantins-Araguaia

A análise do comportamento da precipitação em uma bacia hidrográfica é fundamental para a engenharia e gerenciamento dos recursos hídricos. A Região Hidrográfica Tocantins-Araguaia (RHTA) pela sua ocupação recente e potencialidades econômicas, ganha destaque no cenário nacional. Este trabalho avalia quantitativamente a dinâmica espaço-temporal da precipitação anual nesta região durante um período de 30 anos de dados. A dinâmica da precipitação pode ser analisada pelo cálculo da precipitação média em uma dada área, compondo assim mapas de isoietas de precipitação anual. No entanto, a confecção destes mapas requer um método de interpolação que melhor represente as características pluviométricas em locais não amostrados para posterior análise quantitativa do comportamento da precipitação. Para tanto, foram realizados análises exploratórias descritivas amostral e espacial como requisito de estacionaridade do método de interpolação geoestatístico, ajuste e validação do modelo teórico que se adéque ao variograma de precipitação anual. Após a confecção do mapa de isoietas pelo método de Krigagem Ordinária (sem tendência) e Krigagem Universal (com tendência) foi realizado o cálculo do volume precipitado na região hidrográfica pelo método dos contornos. A dinâmica espacial da precipitação foi realizada com base na análise da estatística descritiva, mapa de isoietas, mapa hipsométrico, Índice de Irregularidade Meteorológica (IMM) e Coeficiente de Variação. A dinâmica temporal foi analisada pela distribuição dos totais anuais de precipitação volumétrica para cada sub-bacia da RHTA, pelo Índice de Anomalia Padronizada, na variação interanual de precipitação e teste de tendência e magnitude representados respectivamente pelo Teste de Mann Kendall e Sen’s. Os resultados correlacionados com as anomalias meteorológicas do Oceano Atlântico (Dipolo) e Pacífico (ENOS) indicam o comportamento da precipitação bastante heterogêneo e com grande variabilidade temporal principalmente na sub-bacia Tocantins-Alto (TOA) (14%). Diminuição da amplitude pluviométrica, em anos de anomalia meteorológica intensa ocasionando um incremento de precipitação ao sul das sub-bacias TOA e ARA e diminuição da precipitação na sub-bacia TOB, em eventos de El Niño. Não se pode comprovar pelo teste de Mann Kendall que há uma tendência estatisticamente significativa no volume precipitado na RHTA, mas o estimador Sen’s dá indícios de queda na precipitação na sub-bacia TOA (-1,24 Km^³/ano) e Araguaia (ARA) (-1,13 Km^³/ano) e aumento da precipitação na sub-bacia do Tocantins Baixo (TOB) (0,53 Km^³/ano) e para a RHTA (-1,5 Km^³/ano). Assim a variabilidade espacial e temporal nas sub-bacias está intimamente relacionada aos eventos de anomalia meteorológica, na qual, a sua ação ocorre de maneira irregular ao longo da área de estudo e pode influenciar as diversas atividades sócio-econômicas na RHTA de acordo com sua magnitude e área de ocorrência.

New records of the Rufous-faced Crake, Laterallus xenopterus (Gruiformes: Rallidae) in Brazil and observations about its habitat

New records of the Rufous-faced Crake, Laterallus xenopterus (Gruiformes: Rallidae) in Brazil and observations about its habitat. The Rufous-faced Crake, Laterallus xenopterus, is a bird that is rarely spotted at Paraguay, central Brazil, and central Bolivia. There are known species records at the Brazilian states of Distrito Federal, Sao Paulo, and Minas Gerais. Here, we provide information about new areas of occurrence for this species in Brazil and detailed observations of its habitats. In October 2012, two individuals were registered in the municipality of Cristalina, state of Goias. In December 2012, the species was found in a new locality of Distrito Federal and at the municipality of Patrocinio, Minas Gerais. In February 2013, a new record for this species was obtained in the municipality of Itiquira, Mato Grosso. In all occasions, the bird was spotted in humid environments, which were characterized by the presence of grass and a thin water layer.

Reposição florestal obrigatória no município de Presidente Venceslau

The growing concern over deforestation of native forests from Brazil to the marketing of wood in various sectors had made greater attention from lawmakers. In this context, did the reforestation, which came into existence to meet the demand for forest raw material. This paper attempts to make a survey, focusing on the interplay between small and medium producers, consumers of forest products and reforestation associations. For this, we conducted a survey of legislation at the federal and state since the emergence, evolution and current context for understanding the legal basis on the subject. In addition, literature reviews have been made seeking to direct the concepts and importance of reforestation, reforestation, forest plantations and productive use of the species Eucalyptus sp for the supply of forest raw material. Approach was also sought on the structure of the system of reforestation of the state of Sao Paulo and their assignments. We also present an in loco study of Chairman Wenceslas municipality in order to analyze the participation of the municipality in the reforest the region of Pontal Paranapanema and actions of regulatory agencies. As a result presents a survey of consumers of timber enterprises in the municipality of President Wenceslas based on the resolution SMA No. 082/2008, which describes the characteristics of these companies and their fields of activity

O trabalho docente na rede pública do estado de São Paulo: apontamentos iniciais para a discussão da jornada de trabalho

The changes in the world of work that, in turn, directly affect the teaching work, have expanded the processes of precariousness and intensification, contributing for deteriorating conditions which teachers use to labor. Considering that the time designated for teaching activities is an important part of work conditions, we look for, in this article, to analyze the work shift of teachers in São Paulo state educational public system. Regarding that teachers are a very heterogeneous group, we have chosen to discuss the workday those professionals who dedicate themselves in the last years of elementary and high school. Through a literature review and a research about the legislation related to the topic, in Brazil and São Paulo state, we have highlighted that the teachers’ work shifts should include not only the time for classroom activities, but also for other extra activities. Moreover, we emphasize that the state of São Paulo government has promoted, since 2012, a reformulation of the teachers’ work shift that has not properly include the appropriate length of time for extra educational activities, contrasting the parameters founded in the national legislation. Besides the legal non-compliance, that fact has accentuated the process of intensification of teaching work, contributing for the embrittlement of the collective activities.

Propostas e currículos estaduais de educação física, avanços e limites no trato de futebol

Football is a sporting phenomenon that unites the collective to individual, because besides the needs of teamwork, it requires several physical individual abilities. The unpredictability of each match turns it into a fascinating and unique sport. Indeed, this is the most popular and admired sport in all over the world, covering a huge amount of fans and practitioners. Curriculum documents are a new and unprecedented fact in history of Physical Education, so it sought as study object investigate and analyze is being treated in many curriculums proposes of seven Brazilian States (Goiás, Maranhão, Pernambuco, Rio de Janeiro, Rio Grande do Sul, Sergipe e São Paulo) and the Distrito Federal. This study has a qualitative character, using documentary research, because it consists by analyze of curriculum documents. As results, stands out the difference between guiding principles in curriculums. However, all of them are based in a new perspective of Physical Education. With regard to the objectives, was evidenced a consensus among the documents examined, which target as Physical Education objective the formation of critical and autonomous individual, besides your insertion in body culture movements, body culture or movement culture. The results showed that all documents, except of Distrito Federal, mention football as content, only Pernambuco, Sergipe and São Paulo showed a further deepening in the theme. Thus, it is believed that it is essential for a better unfolding of football in Physical Education classes a understanding by the students about this sport, not just as a mere act of running after a ball, but as a social phenomenon broad and contextualized

Review of the genus Microphilypnus Myers, 1927 (Teleostei: Gobioidei: Eleotridae) from the lower Amazon basin, with description of one new species

Microphilypnus Myers, 1927 is a genus with three nominal species (M. amazonicus and M. macrostoma from the lower Amazon basin, and M. ternetzi from Orinoco), and is among the most poorly studied groups of Neotropical fishes. In this paper, M. ternetzi and M. macrostoma are redescribed and validated and M. amazonicus is regarded as synonym of M. ternetzi. Also, a new species, M. acangaquara, is described from the lower Amazon.

Characterization of Bean Necrotic Mosaic Virus: A Member of a Novel Evolutionary Lineage within the Genus Tospovirus

Background: Tospoviruses (Genus Tospovirus, Family Bunyaviridae) are phytopathogens responsible for significant worldwide crop losses. They have a tripartite negative and ambisense RNA genome segments, termed S (Small), M (Medium) and L (Large) RNA. The vector-transmission is mediated by thrips in a circulative-propagative manner. For new tospovirus species acceptance, several analyses are needed, e. g., the determination of the viral protein sequences for enlightenment of their evolutionary history. Methodology/Principal Findings: Biological (host range and symptomatology), serological, and molecular (S and M RNA sequencing and evolutionary studies) experiments were performed to characterize and differentiate a new tospovirus species, Bean necrotic mosaic virus (BeNMV), which naturally infects common beans in Brazil. Based upon the results, BeNMV can be classified as a novel species and, together with Soybean vein necrosis-associated virus (SVNaV), they represent members of a new evolutionary lineage within the genus Tospovirus. Conclusion/Significances: Taken together, these evidences suggest that two divergent lineages of tospoviruses are circulating in the American continent and, based on the main clades diversity (American and Eurasian lineages), new tospovirus species related to the BeNMV-SVNaV clade remain to be discovered. This possible greater diversity of tospoviruses may be reflected in a higher number of crops as natural hosts, increasing the economic impact on agriculture. This idea also is supported since BeNMV and SVNaV were discovered naturally infecting atypical hosts (common bean and soybean, respectively), indicating, in this case, a preference for leguminous species. Further studies, for instance a survey focusing on crops, specifically of leguminous plants, may reveal a greater tospovirus diversity not only in the Americas (where both viruses were reported), but throughout the world.

Relação entre violência física, consumo de álcool e outras drogas e bullying entre adolescentes escolares brasileiros

O objetivo deste estudo foi identificar a associação entre o consumo de álcool e outras drogas e o bullying com o envolvimento em situações de violência física entre adolescentes de 13 a 15 anos, em escolas públicas e privadas das capitais brasileiras e do Distrito Federal. Foram analisados os dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2009. Para análise dos dados foi utilizada a regressão logística. A prevalência de envolvimento em situações de violência física foi 12,9% maior no sexo masculino. Em ambos os sexos, foram observadas associações entre violência física e ser vítima de bullying com o uso de drogas ilícitas e efeito potencializado do consumo de álcool e drogas. Para o sexo masculino, o uso de álcool mostrou associação significante com violência física. Morar o pai ou ambos os genitores na residência apresentou associação inversa para violência física no sexo feminino. O conhecimento de fatores associados à violência física entre adolescentes é importante para auxiliar estratégias de promoção da saúde e da cultura de paz, rompendo com a ideia de que a violência entre adolescentes é algo banal e esperado.

Murine Dendritic Cells Transcriptional Modulation upon Paracoccidioides brasiliensis Infection

Limited information is available regarding the modulation of genes involved in the innate host response to Paracoccidioides brasiliensis, the etiologic agent of paracoccidioidomycosis. Therefore, we sought to characterize, for the first time, the transcriptional profile of murine bone marrow-derived dendritic cells (DCs) at an early stage following their initial interaction with P. brasiliensis. DCs connect innate and adaptive immunity by recognizing invading pathogens and determining the type of effector T-cell that mediates an immune response. Gene expression profiles were analyzed using microarray and validated using real-time RT-PCR and protein secretion studies. A total of 299 genes were differentially expressed, many of which are involved in immunity, signal transduction, transcription and apoptosis. Genes encoding the cytokines IL-12 and TNF-alpha, along with the chemokines CCL22, CCL27 and CXCL10, were up-regulated, suggesting that P. brasiliensis induces a potent proinflammatory response in DCs. In contrast, pattern recognition receptor (PRR)-encoding genes, particularly those related to Toll-like receptors, were down-regulated or unchanged. This result prompted us to evaluate the expression profiles of dectin-1 and mannose receptor, two other important fungal PRRs that were not included in the microarray target cDNA sequences. Unlike the mannose receptor, the dectin-1 receptor gene was significantly induced, suggesting that this beta-glucan receptor participates in the recognition of P. brasiliensis. We also used a receptor inhibition assay to evaluate the roles of these receptors in coordinating the expression of several immune-related genes in DCs upon fungal exposure. Altogether, our results provide an initial characterization of early host responses to P. brasiliensis and a basis for better understanding the infectious process of this important neglected pathogen.
