statement of problem: endodontic treatment of necrotic teeth with open apices is a challenge. after ruling out surgery as a treatment scheme and introduction of the multivisit apexification which in turn had its disadvantages, apical plug seems to be a suitable substitute treatment plan for such cases. apical plug makes the treatment through formation of a barrier against the obturating materia...

background: echinococcosis is one of the most important helminthic zoonotic diseases in iran. intestinal scraping tech­nique (ist), the traditional method for diagnosis of the infection in definitive hosts, has many disadvantages including low sus­ceptibil­ity and being expensive, hazardous and laborious. detection of coproantigens in fecal samples by enzyme-linked immu­nosorbent assay (ca-elis...

Application development staffs that build and maintain mainframe application programs to manage business systems have a variety of specialized skills. An integrated development environment, like CA Ideal for CA Datacom, is needed to share storage of batch and online program logic providing version control, an integrated Data Dictionary and the ability to insulate the programmer from transaction...

This document describes the surface realization solution submitted by UCM to the Surface Realization Challenge. The UCM submission operates over the shallow representation of the challenge input. This submission to the surface realization challenge relies on an old-fashioned surface realizer based on unification with a grammar. Because this surface realizer requires fully specified inputs, a co...

The size of a minimum realizer of a partial order is called the dimension of that partial order. Here we initiate the study of minimal realizers which are not minimum. As an aid to the study of such realizers, we associate to each minimal realizer certain critical digraphs. We characterize all such critical digraphs for the antichain on n elements, and consequently deduce that for n > 4, the ma...
