    New concepts of agricultural production should be introduced in Brazilian agriculture to become competitive. The integrated system is an agricultural technology that should be also applied to grape production. The purpose of this work was to evaluate two systems of agriculture production. Two plots (Plot IP), Vitis labrusca grapes and Hybrid, were chosen in fields conducted within the integrated production system (IPS) for juice production. All practices adopted in the plots were documented in a field book to ensure the traceability. The results were compared with Conventional System (CS) production of the same cultivars situated in two neighboring areas. The IPS plots provided a decrease in the amount of fungicides by 36.46% (fungicide g/ha). In Conventional System, 3,000 ml herbicide/ha were used. In IPS, herbicide was not applied due to the maintenance of the ground cover. Grapes produced in this system resulted in a yield 32.08% higher than in CS. There was no insecticide application in any of the two systems. The IPS provided a reduction in pesticide application without affecting yields and the biological assays revealed no presence of metabolism inhibitors. With the IPS, it is possible to product high-quality grapes that are safe for both consumers and farmersTrabalho apresentado nos Proceedings of the 8th International Conference on Integrated Fruit Production held in Kusadasi (Turkey), October 7-12, 2012

    Autochthonous yeast populations from different brazilian geographic indications.

    Yeasts are versatile microorganisms which show heterogeneity in their abilities of aromatic molecules formation. The metabolic conversions may improve the production of a particular compound already formed by the microorganism or promote the production of a completely new biochemicals. These conversions depend on the environment. The microbiome of terroir is unique. If the term terroir is a set of physical properties of a vineyard that contribute to the specific characteristics of its wine, the microorganisms will undoubtedly form an integral part of this concept. There are yeasts, filamentous fungi and bacteria that can affect the quality of the wine. The aim of the present study was to identify the autochthonous yeast populations of grape berries collected from regions with Geographic Indications or under construction. The identification was carried out by an approach, combining Maldi-Tof-MS, PCR-RFLP of the internal transcribed spacer with 5.8S ribosomal DNA (rDNA) (ITS1-5.8S-ITS2) and sequences of the D1/D2 domain of the 26S rRNA gene. Some species are common to different GIs and in some of them other species are completely absent, besides some places are contiguous areas. In some areas, Hanseniaspora opuntiae, Saccharomyces cerevisiae, Pichia myanmarensis and Hanseniaspora uvarum were the predominant species.Também publicado em: CONGRESSO MUNDIAL DA VINHA E DO VINHO, 39., 2016, Bento Gonçalves.

    CODAP: um Consenso Multidisciplinar sobre a Definição, Diagnóstico e Tratamento da Dislipidemia Aterogénica em Portugal

    Introduction and aims: Atherogenic dyslipidemia is an important contributor to residual cardiovascular (CV) risk, but it is underdiagnosed and undertreated. This study aimed to assess the opinion of Portuguese experts to generate a consensus concerning the diagnosis and treatment of atherogenic dyslipidemia, as well as to contribute toward standardization of clinical practice in this disorder. Methods: The study consisted in the application of a questionnaire to an expert panel, following a modified Delphi methodology. Results: The majority (88.4%) of the proposed items were found to be consensual. The expert panel recognized the importance of the atherogenic dyslipidemia phenotype, the role played by low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol as risk markers and therapeutic targets, the choice of statins as first-line lipid-lowering drugs, and the value of associating statins with fenofibrate as a means to reduce residual CV risk. However, the role played by triglycerides in CV risk and the therapeutic value of fibrates lacked consensus. Taking into consideration the state of the art and the opinions expressed in this study, the scientific committee developed a treatment algorithm aimed to improve the perception and treatment of atherogenic dyslipidemia. Conclusions: The experts involved in this study were shown to be familiar with the concept and the importance of atherogenic dyslipidemia. The few situations in which a consensus could not be found were mainly related to the interpretation and/or relevance of the available evidence.info:eu-repo/semantics/publishedVersio

    Disponibilidade e características de resíduos provenientes da agroindústria de processamento de uva do Rio Grande do Sul.

    Os resíduos (bagaço e sementes) da uva usada para vinificação equivalem, a aproximadamente, 20% do peso da uva e os resíduos oriundos da uva usada para elaboração de suco de uvas, podem chegar a 25%. O interesse neste tipo de resíduo para a extração de compostos de valor para a indústria de alimentos e cosméticos tem aumentado nos últimos anos, razão da importância de dimensionar a disponibilidade de resíduos da uva proveniente da agroindústria de suco e de vinho. Para tal, foram realizadas entrevistas com empresas produtoras de suco de uva, vinhos de mesa e vinhos finos de mesa, representativas de indústrias de médio e de grande portes. Em algumas empresas foram colhidas amostras de resíduos de algumas cultivares, visando determinar o peso médio das sementes e da casca e para caracterização de cascas de uvas em relação aos teores de antioxidantes funcionais. Com o uso de dados secundários e das informações levantadas nas empresas, estimou-se a quantidade de bagaço de uvas gerada pela agroindústria, nos anos 2010 e 2011.bitstream/item/104074/1/Comunicado-Tecnico-155.pd

    Significance Of Assessment Experiences During Initial Teacher Training In Physical Education

    This study investigates how students in the final semester of their teacher training program (licensure) at the Center of Physical Education and Sports (CEFD), Espírito Santo Federal University, Brazil, (re)interpret their assessment experiences, an integral component of their teacher training. It employs the narrative as a theoretical and methodological perspective, and it utilizes student portfolios, as well as focus groups and semi-structured individual interviews as inputs for data generation. Ten students in their eighth, or final, semester participated in this study. These were the total respondents to a "call for volunteers" among the 2014 graduating class. The results suggest that the students believe the assessment processes of their teaching practices in physical education are disjointed. They feel that the disciplines that allow them to review their own performance during teacher training are more efficient and play a stronger role in their education.221627
