    La persistencia del conducto arterioso con flujo izquierdo-derecho es una de las patologías cardíacas congénitas más frecuentes en el perro y con un tratamiento quirúrgico totalmente resolutivo. En el presente trabajo se describe un caso clínico con esta patología, aprovechando para hacer una revisión sobre la fisiopatología que provoca el fallo en el cierre del conducto y los métodos diagnósticos para confirmar su existencia, así como de la cirugía y las posibles complicaciones de la misma.The patent ductus arteriosus with left to right flow is one of the most frequent congenital heart diseases in the dog, but with a surgical treatment that produces a total recovery. In the present work, a clinical case of this kind is described, alone with a review of the physiopathology that causes the failure in the closing of the duct and the diagnostic methods to confirrn its existence, together with the surgery and possible complications that may arise

    The decomposition of five different biomass samples was studied in a horizontal laboratory reactor. The samples consisted of esparto grass, straw, Posidonea Oceanic seaweed, waste from urban and agricultural pruning and waste from forest pruning. Both pyrolysis in inert atmosphere and combustion in the presence of oxygen were studied. Different heating rates were used by varying the input speed. Major gas compounds were analyzed. The experimental results show that the amount of CO formed is lower in less dense species. It is also found that there is an increase of hydrocarbons formed at increasing feeding rates, in particular methane, while there is a decrease in the production of hydrogen.Financial support for this work provided by PROMETEO/2009/043/FEDER and ACOMP2010/075 of Generalitat Valenciana (Spain) and CTQ2008-05520 (Spanish MCI)
