Geographical origin authentication of southern Brazilian red wines by means of EEM-pH four-way data modelling coupled with one class classification approach.

EEM data recorded at different pH values was exploited by MCR-ALS in order to determine qualitative information about Brazilian red wines. In addition, the geographical traceability of wines produced in the Serra Gaúcha (Rio Grande do Sul) was carried out by DD-SIMCA considering 53 samples from the target class and 20 from other producing regions. The fluorescence signal corresponds to 9 EEMs recorded at different pH (3-11), generating four-way data. By MCR-ALS decomposition, eight factors were retrieved and related to typical chemical compounds found in red wine. In addition, the EEM pH data was used to build a one-class classification model, considering that MCR scores and all samples of the target class were properly recognised as belonging to the target class, with maximal sensitivity equal to 1. Samples of the non-target class were also adequately rejected by the model, and the specificity was found to be 0.97.

Acessibilidade para usuários de cadeira de rodas em estabelecimentos comerciais: o caso de cidades turísticas da Serra Gaúcha / Accessibility for wheelchair users in commercial establishments: the case of tourist cities of Serra Gaúcha

O artigo visa analisar em que medida os estabelecimentos comerciais de duas cidades turísticas da Serra Gaúcha são acessíveis aos usuários de cadeira de rodas. A pesquisa é de natureza básica, de caráter descritivo e realizada sob o paradigma quantitativo e qualitativo. Foi realizado um estudo de caso em duas cidades da Serra Gaúcha, onde foram analisados 377 estabelecimentos comerciais. Os resultados indicaram que 38,45% dos estabelecimentos estudados oferecem rampas adequadas e somente 1,32% disponibilizam sanitários adaptados. Portas acessíveis foram identificadas em 80,36%, bem superior aos demais itens analisados, porém ainda insuficiente para garantir a acessibilidade universal. Pode-se inferir que se encontrou um número significativo de barreiras arquitetônicas que interferem negativamente na acessibilidade da população local e dos turistas usuários de cadeira de rodas.

The article aims to analyze in what extent the commercial establishments of two tourist cities of the Serra Gaúcha are accessible to wheelchair users. The research has a basic nature, a descriptive character and was performed under the quantitative and qualitative paradigm. The case study was carried out in two cities of the Serra Gaúcha, where 377 commercial establishments were analyzed. The results indicated that 38.45% of the establishments studied offer adequate ramps and only 1.32% offer adapted toilets. Accessible doors were identified at 80.36%, well above the other items analyzed, but still insufficient to guarantee universal accessibility. It can be inferred that a significant number of architectural barriers have been found that interfere negatively in the accessibility of the local population and the wheelchair users.

Faunal analysis and injuries characterization of Polistinae (Hymenoptera, Vespidae) in niagara rosada vineyards in Bento Gonçalves, Rio Grande do Sul state, Brazil / Análise faunística e caracterização de injúrias de Polistinae (Hymenoptera, Vespidae) em parreirais de niagara rosada em Bento Gonçalves, Rio Grande do Sul, Brasil

The State ofRio Grande do Sul is a major producer of grapes in Brazil, highlighting the Serra Gaúcha as the main producing region. In the pursuit of good quality in grapes it is essential the control of pests, especially insects. This study highlights the incidence of wasps, which cause serious damage at harvest time. This study aimed to characterize the community of social wasps (Hymenoptera, Vespidae) through faunal analysis and to examine the relationship of these insects with injuries to the grape berries in vineyards of Bento Gonçalves, Rio Grande do Sul State. Therefore, active search were made in January and February 2014, followed by analysis of frequency, constancy, abundance, dominance and diversity. Ten species of wasps were able to use grape berries as food. The two dominant species were Polybia ignobilis and P. minarum, however, Synoeca cyanea has greater ability to break the intact berries. Other three species, Polistes cavapytiformis, P. versicolor and Brachygastra lecheguana, were also able to break the skin of grapes, but of damaged berries.

O Rio Grande do Sul é o maior produtor de uvas no Brasil, destacando-se a Serra Gaúcha como principal região produtora. Na busca de qualidade das uvas é fundamental o controle de pragas, especialmente insetos. Este trabalho identifica a incidência de vespas que acarretam graves danos na época de colheita. A pesquisa foi conduzida com o objetivo caracterizar a assembleia de vespas sociais (Hymenoptera, Vespidae) através de análise faunística e a relação destas com injúrias as bagas, em parreirais do município de Bento Gonçalves, Rio Grande do Sul. Para tanto, foram realizadas coletas ativas nos meses de janeiro efevereiro de 2014, realizando-se análise de frequência, constância, abundância, dominância e diversidade da comunidade. Foram identificadas 10 espécies de vespas capazes de utilizar as bagas de uva como alimento. As espécies predominantes foram Polybia ignobilis e P. minarum, todavia, Synoeca cyanea apresenta maior capacidade de rompimento de bagas íntegras. P. cavapytiformis, P. versicolor e Brachygastra lecheguanatambém foram capazes de abrir a casca dos frutos em bagas anteriormente danificadas.
