This paper describes a theory formation system which can discover a p a r t i a l axiomization of a data base represented as extensional ly defined binary r e l a t i o n s . The system f i r s t discovers a l l possible in tens ional d e f i n i t i o n s of each binary re la t i on in terms of the others. It then determines a minimal set of these re la t ions from which the others can be def ...

Sialolithiasis is a relatively frequent occurrence; however, cases of sialolithiasis originating around a "foreign body" nidus are rare. We describe a patient with submandibular sialolithiasis organized around a vegetal nidus and discuss the etiology of the case.

knowledge is one of the most important accomplishments of human being in confrontation with phenomena and facts whichhe acquires through his cognitive faculties. throughout the history of philosophy, there was always this confusion that whether or not beliefs are influenced by his non-epistemic areas and external elements, and if so, is it epistemically acceptable or the agent should avoid thes...

The tube wave, or low-frequency manifestation of the Stoneley wave, has been modeled previously using the quasi-static approximation; I extend this method to include the effect of the formation matrix compressibility, which tends to marginally increase the tube-wave attenuation. Using the Biot theory of poroelasticity, I develop a fully dynamic description of the Stoneley wave. The dispersion r...
