There exists a large amount of knowledge representation models. But most of them have significant limitations at the epistemic level. They do not have explanatory power. Most of them do not have means to represent some functional needs to work…

The aim of this work is to relate two apparently independent concepts as belief revision and relevance. We propose a formal characterization for the notion of (ir)relevance by means of a set of postulates. Then we define (ir)relevance using change…

The purpose of the present paper is to review the current knowledge about cholesterol gallstone disease. It is generally accepted that the formation of cholesterol gallstone requires three major pathogenic defects, namely, supersaturation, nucleation and crystal growth as well as…

Several epidemiological and intervention studies have been performed in Mexico in order to evaluate control strategies against Taenia solium cysticercosis. Epidemiological questionnaires and immunodiagnostic assays indicate that the main risk factor for acquiring cysticercosis is the tapeworm carrier. Two control…

In the UK, a series of policies and practices since
the 1980s have increasingly involved service users
and carers in the policy and planning of mainstream
