    AbstractThis paper focuses on demand response in a smart grid scope using a fuzzy subtractive clustering technique for modeling demand response. Domestic consumption is classified into profiles in order to favorable cover the adequate modeling. The fuzzy subtractive clustering technique is applied to a case study of domestic consumption demand response with three scenarios and a comparison of the results is presented. The demand response developed model intends to support consumer's decisions given a compromise between the consumption imperative needs and possible economical benefits due to reshape and reschedule

    Currently the cultivation of grapes for grape juice production has gained ground in new regions of Brazil, as the example in the São Francisco Valley (SFV) located in the Northeastern of Brazil between the parallels 8:09° Southern Hemisphere and 40W longitude in a tropical semi-arid climate. Companies have invested in the production of grape juice on a commercial scale in this region is estimated in 2015 a volume of 1.5 million liters of whole juice. However, viticulture practiced in VSF (Tropical Viticulture) is different from other traditional regions of the world, for the same vine produces two crops per year, with this, the wineries are planning the time when they intended to harvest the grapes and perform production pruning vines at different times, by adopting a scaling system to be distributed crops throughout the month, and several months of the year. The aim of this study was to evaluate how physical and chemical characteristics of the elaborate hp grape juices with. cv. Isabel precocious and BRS Violeta, harvested at different maturity stages in the São Francisco Valley

    Spread of vaccinia virus to cattle herds, Argentina, 2011

    To the Editor: Since 1999, several zoonotic outbreaks of vaccinia virus (VACV) infection have been reported in cattle and humans in rural areas of Brazil. The infections have caused exanthematous lesions on cows and persons who milk them, and thus are detrimental to the milk industry and public health services (1,2). In Brazil during the last decade, VACV outbreaks have been detected from the north to the extreme south of the country (1–4). Because Brazil shares extensive boundaries with other South American countries, humans and cattle on dairy and beef-producing farms in those countries may be at risk of exposure to VACV. To determine if VACV has spread from Brazil to Argentina, we investigated the presence of VACV in serum samples from cattle in Argentina.Facultad de Ciencias VeterinariasComisión de Investigaciones Científicas de la provincia de Buenos Aire
