TL;DR: In this paper, the authors report that o volume do comercio interes-tadual cresceu em relacao ao PIBpc da regiao principal-mente pelo aumento das vendas e, embora a regiao con-tinue deficitaria, alguns estados passaram a ter superavit no comerio interestadual.
Abstract: A insercao do Nordeste na divisao inter-regional do trabalho pode ser captada atraves dos fluxos de comercio interestaduais e internacionais. Neste artigo, o foco esta centrado nas relacoes comerciais internas, intrarregionais e internacionais no ano de 2006. Os resultados revelam que o PIB do Nordeste cresceu mais que o nacional entre 2002 e 2009 e seu comercio interestadual aumentou mais que proporcionalmente em relacao aos resultados observados em 1999. As transacoes intrarregionais constituem importante fonte de demanda e oferta de bens e servicos. A balanca comercial internacional foi superavitaria em 2006, embora haja alternância com deficits em outros anos. O volume do comercio interestadual cresceu em relacao ao PIBpc da regiao principalmente pelo aumento das vendas e, embora a regiao continue deficitaria, alguns estados passaram a ter superavit no comercio interestadual. O comercio internacional cresceu mais que proporcionalmente ao PIBpc, mas as trocas internas continuaram sendo preponderantes para todos os estados nordestinos.

10 Jun 2019TL;DR: A serra do Tepequem, area foco do estudo, localiza-se no estado de Roraima no municipio do Amajari as mentioned in this paper.
Abstract: A serra do Tepequem, area foco do estudo, localiza-se no estado de Roraima no municipio do Amajari. Destacase na paisagem por apresentar variacoes altimetricas formando um conjunto de morros alinhados, colinas e escarpas abruptas. Geologicamente, corresponde a um testemunho isolado formado em rochas sedimentares de idade Paleoproterozoica, composta por arenitos, arenitos conglomeraticos, siltitos e argilitos, pertencentes a Formacao Tepequem. Os solos sao arenosos recobertos parcialmente por savana arbustiva rasteira. O clima e quente e umido (Am) com temperaturas medias em torno de 22 graus, com elevado indice pluviometrico em media de 2.250mm anuais. A declividade da area e representada por valores que variam de > 0,1o a < 4o. A combinacao dos elementos fisiograficos auxiliam na evolucao da paisagem, podendo ser evidenciada no surgimento e evolucao de feicoes erosivas lineares. Objetivou-se atraves desse estudo identificar as feicoes erosivas, bem como, seus condicionantes.

27 Apr 2020TL;DR: In this paper, a revisao critica da literatura observando as publicacoes disponiveis nas bases Medline, Lilacs, and Scielo is presented.
Abstract: Concepcoes de mitos e relacoes com a saude. Os mitos estao presentes desde a antiguidade na vida das pessoas, sendo intimamente relacionados com as crencas e a cultura de cada populacao. O objetivo do estudo foi analisar as concepcoes sobre mitos e suas relacoes com a saude na perspectiva teorico-pratica dos diferentes estudos presentes na literatura. O metodo utilizado para este estudo foi o da revisao critica da literatura observando as publicacoes disponiveis nas bases Medline, Lilacs e Scielo. Foram selecionados artigos nas linguas portuguesa, inglesa e espanhola num total de 213 artigos, foram consultados tambem livros, teses e dissertacoes, do periodo de 1988 a 2013. Esta revisao destacou uma serie de estudos de acordo com as categorias: definicoes sobre mitos, presenca dos mitos nas religioes Candomble e a Umbanda, concepcoes de mitos relacionados a saude. Observa-se atraves dos seculos a existencia das concepcoes sobre o significado da palavra mito. Muitos autores correlacionam os mitos com a evolucao historica da humanidade e associam a valores culturais, crencas e tradicoes. E fundamental o desenvolvimento de uma assistencia da saude voltada para as comunidades e para as pessoas que trazem consigo em particular suas crencas, origens sociais, economicas e culturais.

TL;DR: An important finding of this study was that the dams of the puppies in G1 and G2 were positive for P. gingivalis before and after dental eruption, hoping to contribute to early guidance of oral hygiene management and prevent future PD.
Abstract: Background: Periodontal disease (PD) is the most common disease of the oral cavity in cats and dogs, and it affects up to 80% of these animals. PD begins with the accumulation of bacteria on the surface of the teeth, and it poses a risk for the health of pets. Research on PD in dogs has focused on the identification and characterization of bacterial communities present in the oral cavity. Porphyromonas gingivalis is highly prevalent in the oral cavity. Therefore, the aim of this study was to detect P. gingivalis before and after dental eruption in 15 English bulldog newborn puppies, hoping to contribute to early guidance of oral hygiene management and prevent future PD. Materials, Methods & Results: Fifteen English bulldog newborn puppies were used in this study. Two groups (G1 and G2) were formed with eight and seven puppies, respectively. Oral swab samples were taken from the maxillary incisor region of animals from G1 and G2 10 days after birth (T10). At this moment, the clinical evaluation of the oral cavity showed healthy gums with a thin, shiny, pinkish, and firm margin, without any odor or granular appearance, and with no tooth eruption. On postnatal day 25 (T25), a subgingival sample was collected with a Gracey curette from the maxillary incisors; the oral cavity examination revealed healthy gums and presence of gingival sulcus. Bilateral subgingival samples were also collected from the maxillary canines and fourth premolars of the dams at T10 and T25. All newborn puppies were fed maternal breast milk and supplementation exclusively with commercial milk for dogs in individual bottles. The dams were fed commercial dry food. The average weight of G1 and G2 at T10 was 625.87 ± 85.26 g and 543.50 ± 92.88 g, respectively, and 100% (15/15) of the animals were negative for PG as assessed by polymerase chain reaction (PCR) on oral swab samples. At T25, puppies from groups G1 and G2 weighed 1.465 ± 194 g and 1.206 ± 201 g, respectively, and 100% (15/15) of the puppies were positive for P. gingivalis as assessed by PCR on subgingival samples collected with a Gracey curette. The dams of the puppies in G1 and G2 were positive for PG at T10 and T25 as determined by PCR on subgingival samples. Discussion:An important finding of this study was that the dams of the puppies in G1 and G2 were positive for P. gingivalis at T10. Several species of bacteria that cause periodontal disease can be transmitted from humans to pets; therefore, transmission from dam to puppy would be possible, but was not observed in this study at T10, when 100% (15/15) of the animals were negative for P. gingivalis. Subgingival microbiota associated with periodontitis consists essentially of Porphyromonas spp., and the presence of gingival sulcus and dental eruption are determinant factors for the presence of P. gingivalis in the oral cavity. Nevertheless, the hygiene habits of dogs, with the dam licking the puppies after dental eruption, could have been a relevant factor for transmission and appearance of P. gingivalis in the subgingival sample in 100% (15/15) of the puppies at T25. The oral microbiota is closely related to many diseases, and resident pathogenic oral bacteria can be transferred by close contact. Certain species of bacteria present in the subgingival biofilm exhibit higher etiologic relevance during the onset and progression of periodontitis, and Porphyromonas spp. is among the most important of these species. It is important to keep in mind that age is a relevant factor to prevent periodontitis. Therefore, providing owners with instructions for thorough dental brushing of animals when they still have deciduous teeth can prevent the appearance of future PD.
