Little has been studied of the food metrics most chondrichthyans, which provide baseline information for assessment fishing status to guide development ecosystem-based management plans. Therefore, main goal this study was approach isotopic niche Dipturus chilensis and Callorhinchus callorynchus in Valparaíso (central Chile). The findings showed that C. presented a narrow ellipse (E= 0.79; RC= 4...

My Ph.D. dissertation (Calistri 1990) extends traditional methods of plan recognition to handle situations in which agents have flawed plans.1 This extension involves solving two problems: determining what sorts of mistakes people make when they reason about plans and figuring out how to recognize these mistakes when they occur. I have developed a complete classification of plan-based misconcep...

In this paper, we have shown that complex planning problems and non-monotonic strategies nd natural logic-based formulations in the framework of deductive database languages. In particular, we have shown how totally and partially ordered plans can both be modeled using XY-stratiied Datalog 1S programs. The framework proposed is exible, amenable to eecient implementation, and supportive of varia...

PURPOSE To evaluate whether Co-60 is equivalent to Ir-192 for HDR cervical brachytherapy, through 3D-DVH dose comparisons in standard and optimised plans. Previous studies have only considered 2D dosimetry, point dose comparisons or identical loading. Typical treatment times and economics are considered. MATERIAL AND METHODS Plans were produced for eight cervix patients using Co-60 and Ir-192...
