In chordate phylogeny, changes in the nervous system, jaws, and appendages transformed meek filter feeders into fearsome predators. Gene duplication is thought to promote such innovation. Vertebrate ancestors probably had single copies of genes now found in multiple copies in vertebrates and gene maps suggest that this occurred by polyploidization. It has(More)
A formal selection and pruning technique based on the concept of local relative sensitivity index is proposed for feedforward artificial neural networks. The mechanism of backpropagation training algorithm is revisited and the theoretical foundation of the improved selection and pruning technique is presented. This technique is based on parallel pruning of(More)
The mode of action of the antimicrobial agent, 5-bromo-5-nitro-l,3-dioxane (bronidox), was studied in detail for gram-positive and gram-negative bacteria, yeast and fungi. The studies included MIC testing, thiol inhibition of activity, intracellular leakage, oxygen consumption, incorporation of3H-uridine, scanning electron microscopy, inhibition of enzyme(More)
The minimum inhibitory concentration values against Gram-negative and Gram-positive bacteria were determined and compared for a selected group of synthesized alpha-substituted 2-methyl-5-nitrofuran derivatives. In vitro oxidation of thiols to disulfides by 2-(iodomethyl)-5-nitrofuran indicated that oxidation of enzyme-thiol groups to disulfide bonds was a(More)
Material handling operations are used widely in industry. Often they produce unacceptable levels of dust. This article proposes a systematic approach to dust control for material handling operations. It focuses on the appropriate dust control technologies for the wide range of material handling operations. Both dust collection and dust suppression systems(More)
Geographic information science increasingly meets cognitive science, as comprehending (i.e. perceiving and conceptualising) spatial characteristics induces spatial cognition and behaviour. However, the widely deployed models of space fail in accounting for those conceptualisation mechanisms. In this context, the present work aims at relating human spatial(More)
This document defines an authorization policy language for controlling access to location information. It extends the Common Policy authorization framework to provide location-specific access control. More specifically, this document defines condition elements specific to location information in order to restrict access to data based on the current location(More)

This document defines an extension to the Presence Information Data Format Location Object (PIDF-LO) (RFC 4119) for the expression of location information that is defined relative to a reference point. The reference point may be expressed as a geodetic or civic location, and the relative offset may be one of several shapes. An alternative binary(More)
