To develop an alternative method for production of sarsasapogenin by plant tissue culture technique and its quantification in Asparagus racemosus and its in vitro cultures using HPTLC. Murashige and Skoog’s (MS) basal medium supplemented with various growth regulators was used for development of shoot and root calli while, hormone free MS medium was used for development of Agrobacterium tumefac...

This paper proposes a natural term language, investigates some of its properties , and discusses some of the advantages of natural term logic (NTL) as a medium for natural language semantics over its rivals and ancestors.

natural hazards in the form of floods, quakes, cyclones, and the like have existed since the earth has come to being. in recent decades, in spite of scientific and technological developments in forecasting incidents, building construction and crisis management have imposed heavy expenses on human societies. the importance of many natural hazards is so great that to predict the very occurrence a...

In this paper natural convection heat transfer within a two-dimensional, horizontal, concentric cam shape cylinders that is partially filled with a fluid saturated porous medium has been investigated. both cylinder are kept at constant and uniform temperatures with the outer cylinder being subjected relatively lower than the inner one. In addition the forchheimer and brinkman effect are taken i...

A number of efforts have been made in recent years to define standards for the description of resources (including web services) in services oriented architectures. These standards often use description logic ontologies (for example, OWL-S) and are intended to be machine-readable. They have been applied to geospatial web services to describe the functions that those services perform in a way th...

Entities on the Web of Data need to have labels in order to be exposable to humans in a meaningful way. These labels can then be used for exploring the data, i.e., for displaying the entities in a linked data browser or other front-end applications, but also to support keywordbased or natural-language based search over the Web of Data. Far too many applications fall back to exposing the URIs of...

A polarized maser is assumed to operate in an anisotropic medium with natural modes polarized differently to the maser. It is shown that when the spatial growth rate and the generalized Faraday rotation rate are comparable, the polarization of the growing radiation is different from those of the maser and medium. In particular, for a lineary polarized maser operating in a medium with linearly p...

large number of clinical cases in endodontics, however, cytotoxicity of such sealers must be tested before their validation as fi lling materials. the aim of this study was to evaluate the cytotoxic effect of a new copaiba oil-based root canal sealer (biosealer [bs]) on osteoblast-like osteo-1 cells. materials and methods: the experimental groups were formed according to the culture medium cond...
