MOTIVATION When targeted to a barcoding region, high-throughput sequencing can be used to identify species or operational taxonomical units from environmental samples, and thus to study the diversity and structure of species communities. Although there are many methods which provide confidence scores for assigning taxonomic affiliations, it is not straightforward to translate these values to un...

Comparative taxonomical and phytochemical studies of B diffusa ands B. verticillata are described in this article.

Many virulence genes have been detected in attenuated mutants of Brucella melitensis 16 M; nevertheless, a complete report of these genes, including the main Cluster of Orthologous Groups (COG) represented as well as the taxonomical distribution among all complete bacterial and archaeal genomes, has not been analyzed. In this work a total of 160 virulence genes that have been reported in attenu...

This study was aimed description of morphological features fruits and seeds eight species related to Brassicaceae family in Iraq, the showed number taxonomic differences as silique long all studied except Rorippa amphibian (L.)b Besser short, however varied dimensions where Turritis laxa L. recorded highest average length with (160 mm) while R .amphibia record shortest (5 mm), addition colors r...

Mosses (a section of bryophytes), are considered as an important group of non-flowering plants which a modern computer-assisted database system is not yet prepared for their determination and description key in Iran. Following a software package recently designed under a research project for assessment of moss diversity of Iran by the authors, the present paper is prepared to: I) introducing co...

“ eutral” electronic marketplaces fail because their structure and mode of operation does not allow for the effective accommodation of multiple business models that could serve the interests of a critical mass of adopters. We propose a fresh approach for the creation of economically viable “neutral” electronic marketplaces showing that this can be accomplished through the ability to transcend t...

The aim of this paper is to propose a logical way to handle uncertain knowledge and change. Databases, diagnostic, planiication, taxonomy are some of the domains concerned by this problem. This paper focuses on the means Linear Logic ooers to represent taxonomical networks and to perform updates of databases containing incomplete information. The two problems are rst expressed in graph theory: ...

The paper presents an approach to the description of ontologies used in Multi-Agent Systems as a means to allow interoperability of such systems. It is inspired by a pragmatic theory of intensionality worked out as part of an anthropological approach to agent migration. A new formalisation of how an intensional ontology can be ascribed to a society of agents is presented, together with a first ...
