A RESPONSABILIDADE CIVIL DOS CORRETORES DE SEGURO À LUZ DO ORDENAMENTO JURIDICO BRASILEIRO
O artigo trata da Responsabilidade Civil dos corretores de seguros à luz do ordenamento jurídico brasileiro, sendo desenvolvido sobre o exercício da corretagem, habilitação profissional e responsabilidade dos mesmos frente a atos lesivos. O desenvolvimento das atividades de seguros tem passado não só pela participação das sociedades, pela satisfação dos interesses dos particulares que pretendem ver seu patrimônio protegido, como, também, pelo Corretor de Seguros que, dotado de conhecimentos técnicos, faz a aproximação entre o segurado e a seguradora. Conclui-se que o corretor é profissional e maior é a sua responsabilidade, como tal, deve estar atento a detalhes do negócio que o homem comum talvez não tenha condições de perceber

O USO DA BOMBA MANUAL EM CISTERNAS DE ÁGUA DE CHUVA
O aproveitamento da água de chuva no Semiárido tem contribuído para a melhoria da condição de vida da população, evidenciada pela redução da prevalência das doenças diarreicas. Essa melhoria pode ser ainda maior se forem tomados cuidados com a retirada da água da cisterna, o que pode ser feito por meio do uso de bomba. Entretanto, encontra-se um baixo percentual de utilização desses dispositivos. O presente trabalho tem como objetivo analisar o desempenho hidráulico de uma bomba manual e o esforço físico necessário para sua operação. A pesquisa foi realizada na Universidade Estadual de Feira de Santana com a instalação de uma bomba manual em uma cisterna para diferentes alturas, sendo realizados 10 ensaios com operadores diferentes recrutados entre os estudantes e funcionários do curso de engenharia civil. O operador devia manter uma cadência de 60 batidas por minuto e um deslocamento do êmbolo de 30cm, indicado por uma marca de tinta. Para cada ensaio, foi registrado o tempo necessário para encher um recipiente de 10,0L, o número de batidas e a frequência cardíaca do operador antes e depois do teste. Verificou-se que a bomba manual é capaz de retirar água da cisterna a uma vazão maior que 10,0L/minuto, com um esforço que poderia ser classificado como leve a moderado, concluindo que esse tipo de equipamento é adequado para uso pela população local.
Nutritional efficiency of Stylosanthes guianensis cv. Mineirão according to soil correction
The main expectation for using leguminous plants in pastures is improving animal production and reducing production costs. This research was carried out in a greenhouse, in order to evaluate the effect of two soil acidity correctives and P rates on P, Ca, Mg, Si, raw protein (RP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility (IVDMD) contents of Stylosanthes guianensis cv. Mineirão. A randomized blocks design was used in a 5x2 factorial arrangement, with five P rates (50 mg dm-3, 100 mg dm-3, 200 mg dm-3, 400 mg dm-3, and 800 mg dm-3 of soil) and two soil correctives (lime and Ca and Mg silicate), with three replications. Both lime and silicate applications, previously to the phosphate fertilization, assured P, Mg, Ca, RP, NDF, and ADF contents, in plants of Mineirão, compatible with good performances of grazing animals. The increase in the silicon content in Mineirão, resulting from silicate application, did not reduce the IVDMD. The substitution of lime by Ca and Mg silicate did not affect the nutritional value of the Mineirão subjected to phosphorus rates
Representações Sociais que permeiam a formação inicial de futuros professores sobre "Ser Professor de Ciências"
Este estudo teve como propósito investigar como a formação inicial docente pode interferir nas possíveis Representações Sociais (RS) sobre "Ser Professor de Ciências". Participaram da pesquisa 16 licenciandos do primeiro e último ano de um curso de Ciências de uma universidade pública brasileira localizada na região sul do país. Para a coleta dos dados foi utilizada a evocação livre de palavras, concentrando a análise no núcleo central das representações e entrevista com grupo focal, a qual permitiu maior aprofundamento da análise. Enfim, identificamos que apesar da insegurança em relacionar conceitos pedagógicos e científicos, esses licenciandos consideram que ser professor de ciências está atrelado a um conjunto de fatores, como ser dinâmico, criativo e reflexivo
Sedimentology of the proximal portion of a large-scale, Upper Jurassic fluvial-aeolian system in Paraná Basin, southwestern Gondwana
Upper Jurassic sedimentary rocks of Guará Formation record the environmental and geotectonic changes of the early break-up stages in the southwestern portion of Gondwana. Newly-described occurrences of this formation allow the expansion of its areal distribution to the central part of the Paraná Basin, Brazil. Four vertical sections are presently described in Paraná State, Brazil. Nineteen lithofacies were grouped in five facies associations, through the classical method of facies analysis. The facies analysis included Guará Formation and the adjacent portions of the underlying Pirambóia Formation and the overlying Botucatu Formation. The depositional system of Pirambóia Formation was wet aeolian fluvial-influenced and is composed by aeolian dunes, aeolian sandsheets/interdunes and ephemeral fluvial deposits facies associations. The Guará Formation is composed of multistorey fluvial facies association constituting a highly amalgamated perennial fluvial system. It is overlaid by the Botucatu Formation, characterized as a dry aeolian system formed by aeolian dune deposits. The stratigraphic units are separated by regional unconformities marked by a shift in facies and depositional systems that reflect climatic changes. The Guará Formation depositional model, established in correlation with southern sections, represents a broad fluvial system with aeolian interaction deposited in a wide basin with more than 800 km in extension. This large depositional paleoenvironment, together with other Upper Jurassic records in southwestern Gondwana, represents the early rift stage of Gondwana break-up

Rarity of monodominance in hyperdiverse Amazonian forests.
Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates
Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis).
Time period: Tree-inventory plots established between 1934 and 2019.
Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm.
Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield.
Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes.
Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests.
Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
Geography and ecology shape the phylogenetic composition of Amazonian tree communities
AimAmazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.LocationAmazonia.TaxonAngiosperms (Magnoliids; Monocots; Eudicots).MethodsData for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny.ResultsIn the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.Main ConclusionNumerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions
