We analyze a symmetric n-firm Cournot oligopoly with a heterogeneous population of optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a là Vega-Redondo (1997). Optimizers play a myopic best response to the opponents’ previous output. Firms are allowed to make mistakes and deviate from the decision rules with a small probability. Appl...

This paper explores the impact of memory in Cournot oligopolies where firms learn through imitation of success as suggested in Alchian (1950) and modeled in Vega-Redondo (1997). As long as memory includes at least one period, the long-run outcome corresponds to any quantity between the Cournot one and the Walras one. The (evolutionary) stability of the walrasian outcome relies on inter-firm com...

The effect of organic and conventional agricultural systems on the physicochemical parameters, bioactive compounds content, and sensorial attributes of tomatoes ("Redondo" cultivar) was studied. The influence on phytochemicals distribution among peel, pulp and seeds was also accessed. Organic tomatoes were richer in lycopene (+20%), vitamin C (+30%), total phenolics (+24%) and flavonoids (+21%)...

The integral relations formalism introduced in [P. Barletta et al., Phys. Rev. Lett. 103, 090402 (2009); C. Romero-Redondo et al., Phys. Rev. A 83, 022705 (2011)] and designed to describe 1 +N reactions is extended here to collision energies above the threshold for the target breakup. These two relations are completely general, and in this work they are used together with the adiabatic expansio...

The objective of this study was to identify the perceptions of people with tuberculosis regarding their health needs. This qualitative study was performed in the administrative district of Capão Redondo, São Paulo. Data collection was performed in January of 2010 via semi-directed interviews. The interviews were conducted with eleven people undergoing tuberculosis treatment. The participants we...

Os corpos estranhos nas fossas nasais são causas frequentes de recurso à urgência, sobretudo em idade pediátrica.Na maioria dos casos inofensivos, podendo permanecer vários dias sem causar lesões. As pilhas sendo uma exceção,representam importante ameaça com necessidade remoção urgente.Descreve-se o caso criança 4 anos idade, observada no Serviço Urgência suspeita corpoestranho na fossa nasal. ...
