A series of 3-substituted-4-(5-nitro-2-furfurylidene)amino-5-mercapto-1,2,4-triazoles 3 and their Mannich bases have been synthesized. The structures of these Schiff bases and Mannich bases were confirmed on the basis of elemental analysis, H NMR and mass spectral data. The above compounds were also screened for their antifungal activity against C.albicans.

This paper reviews various bases used by investigators in the biomedical field for expressing analytical data obtained from biological tissues. The advantages of certain units of reference in certain research situations and the pitfalls of other modes of expression are discussed. I suggest that authors express their data using several bases when no particular one is fully adequate. Use of wet w...

In this paper we investigate a new notion of bases in Hilbert spaces and similar to fusion frame theory we introduce fusion bases theory in Hilbert spaces. We also introduce a new denition of fusion dual sequence associated with a fusion basis and show that the operators of a fusion dual sequence are continuous projections. Next we dene the fusion biorthogonal sequence, Bessel fusion basis, Hil...

Integrating knowledge from multiple sources is an important aspect of automated reasoning systems. In the rst part of this series of papers, we presented a uniform declarative framework, based on annotated logics, for amalgamating multiple knowledge bases when these knowledge bases (possibly) contain inconsistencies, uncertainties, and non-monotonic modes of negation. We showed that annotated l...

We propose to apply classical development methodologies to the design and implementation of Lexical Databases(LDB), which embody conceptual and linguistic knowledge. We represent the conceptual knowledge as an ontology, and the linguistic knowledge, which depends on each language, in lexicons. Our approach is based on a single language-independent ontology. Besides, we study some conceptual and...

The amount of information that is available in computerized form is growing steadily. Two developments in recent years the growth of communication networks and the advent of videotex systems provide the potential for allowing the public convenient access to this information. In this paper we explore the nature of the mechanism by which people in their homes using a videotex information service ...

Recent developments have made it clear that the Semantic Web will not only consist of RDF data and OWL ontologies but also of knowledge formulated as rules, hence the visualization of rules will also be an important part of user interfaces for the Semantic Web. In this paper we describe novel ideas and their prototypical implementation for the visualization of rule bases. In the creation of the...

The constant growth of volume and velocity of knowledge bases on the Linked Data Web has led to an increasing need for scalable linking techniques between resources. Modern data-driven applications often have to integrate large amounts of data relaying on fast but accurate Link Discovery solutions. Hence, they often operate under time or space constraints. Additionally, most Link Discovery fram...

In [6] the authors give an algorithm for answering conjunctive queries over ALCN R knowledge bases which is coNP in data complexity. Their technique is based on the tableau technique for checking sat-isfiability in ALCN R presented in [2]. In their algorithm, the blocking conditions of [2] are weakened in such a way that the set of models their algorithm yields suffices to check query entailmen...

To calibrate Fourier analysis of S5 ranking data by Markov chain Monte Carlo techniques, a set of moves (Markov basis) is needed. We calculate this basis, and use it to provide a new statistical analysis of two data sets. The calculation involves a large Gröbner basis computation (45825 generators), but reduction to a minimal basis and reduction by natural symmetries leads to a remarkably small...
