In areas contaminated by potentially toxic elements (PTEs), knowledge of processes metal mobilisation is the basis for choice appropriate remediation methodologies. The metals a function several factors, and response to these factors must be well known during planning strategies. activity an ore metallurgical plant in South-East Brazil resulted major contamination heavy metals. Reversing contam...

The objective of this study is to develop crystallo-co-agglomeratesof metronidazole having improved physicochemical, compressibility andsolubility properties. process agglomeration employed the use ofdichloromethane (good solvent), ethanol (bridging liquid) and distilled water (poorsolvent). Micromeritic properties co-agglomerates werestudied in terms bulk density, tapped Carr's index, Hausner’...

With the rapid growth of sequence databases, there is an increasing need for reliable functional characterisation and annotation of newly predicted proteins. To cope with such large data volumes, faster and more effective means of protein sequence characterisation and annotation are required. One promising approach is automatic large-scale functional characterisation and annotation, which is ge...

Clique-width of graphs is defined algebraically through operations on graphs with vertex labels. We characterise the clique-width in a combinatorial way by means of partitions of the vertex set, using trees of nested partitions where partitions are ordered bottom-up by refinement. We show that the correspondences in both directions, between combinatorial partition trees and algebraic terms, pre...

In-situ three terminal electron field emission characterisation of an isolated multiwalled carbon nanotube has been performed. Both anode and gate electrodes are attached to high precision piezo-drivers allowing for the characterisation of single emitters. All measurements are performed in a scanning electron microscope allowing accurate knowledge of the local environment of the nanotube to be ...

We present a characterisation of conjugacy in Thompson’s group using the natural action of F on the interval [0, 1]. This characterisation completes the program begun by Brin and Squier [BS01]. Our characterisation also provides another solution to the conjugacy problem in Thompson’s group which was first solved by Guba and Sapir using diagram groups [GS97]. A number of other solutions exist du...

The paper presents a complete characterisation of the families of networks in which distributed computations can be performed in a process terminating manner, that is, with explicit termination in the asynchronous message passing model. The characterisation encompasses all criteria that have been formulated in the past that were known to influence explicit termination: topological restriction (...

Brinzolamide (BZ) is an intraocular pressure reducing agent with low bioavailability. The purpose of the present study was to overcome this issue by development of BZ containing nanoemulsions (NEs) as an ocular drug delivery system with desirable therapeutic efficacy. Brinzolamide NEs were prepared by the spontaneous emulsification method. Based on initial release studies, twelve formulations w...
