    The note describes a proposal for a large acceptance magnetic spectrometer based on a novel superconducting magnet technology, equipped with a silicon tracker and a 3D isotropic calorimeter. ALADINO (Antimatter Large Acceptance Detector IN Orbit) is conceived to study antimatter components of the cosmic radiation in an unexplored energy window which can shed light on new phenomena related to the origin and evolution of the Universe, as well as on the origin and propagation of cosmic rays in our galaxy. The main science themes addressed by this mission are therefore the origin and composition of the Universe (by means of direct search for primordial anti-nuclei in the Cosmic Ray (CR) flux and indirect search for Dark Matter signals in the CR anti-particle fluxes) as well as the origin and propagation of CR in the Galaxy (by means of precise measurements of the energy spectra and chemical composition of the CR)

    Foram estudadas as “performances” e as características da carcaça em uma amostra de um rebanho da raça Piau. O experimento foi feito com 20 suínos distribuídos em lotes de 4 animais com cinco repetições. Os resultados mais importantes obtidos foram: a) 239 dias de idade para alcançar 90 kg; b) ganho diário, 0,469 kg; c) peso da carcaça resfriada, 71,348 kg; d) comprimento da carcaça resfriada, 69,48 cm; e) espessura do toucinho, 5,39 cm; f) total dos cortes nobres, 32,82% e 26,93% em relação à carcaça resfriada e ao peso vivo, respectivamente e g) área do olho do lombo entre a 10.ª e a 11.ª costelas, 18,12 cm. Os resultados encontrados pelo teste "t" mostram que as características gerais da carcaça e as percentagens dos cortes nobres sobre o peso vivo e sobre a carcaça foram inferiores às do suíno tipo carne, sendo as diferenças altamente significativas (exceção do comprimento da carcaça).The performance and characteristics of carcass were studied in Piau's race. The experiment was carried out with 20 hogs, divided in five treatments, with four repetitions. The most important obtained results were: a) days to reach 90 kg; b) daily gain, 0.469 kg; c) weight of the cooled carcass 71.348 kg; d) length of the cooled carcass 69.48 cm; e) lard thickness 5.39 cm; f) total of prime cuts in relation to the cooled carcass 32.82% and 26.93% with respect to the living weight, and g) loin-oye area between the 10 th and the 11 th ribs 18.12 cm2. The results obtained by the "t" test demonstrate that the general characteristics of the carcass and the percentages of the prime cuts, related to the live weight and to the carcass, were inferior to the pig meat type, with highly significant differences (with exception of the length of the carcass)
