Gel filtration and ion exchange chromatography and immobilized alpha-macroglobulin were used to purify this protein and the removal of the contaminating proteases did not diminish the in vivo or in vitro activity of enhancin.

The language Hi(DL-LiteR) is obtained from DL-LiteR by adding meta-modeling features, and is equipped with a query language that is able to express higher-order queries. We investigate the problem of answering a particular class of such queries, called instance higher-order queries posed over Hi(DL-LiteR) knowledge bases (KBs). The only existing algorithm(More)
Ontology-based data access (OBDA) is a novel paradigm for accessing large data repositories through an ontology, that is a formal description of a domain of interest. Supporting the management of OBDA applications poses new challenges, as it requires to provide effective tools for (i) allowing both expert and non-expert users to analyze the OBDA(More)

Roughly speaking, a metaconcept is a concept whose instances can be themselves concepts, and a metaproperty is a relationship between(More)
