the nanoparticles of ti and tio2 have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, pigment and cosmetic manufacturing and biomedical engineering. through this project, a one-step bulk synthesis method of electromagnetic levitational gas condensation (elgc) was utilized for the synthesis of monodispersed and crystalli...

This paper offers an empirical study of the role of technology in an organisational change and learning process. My focus is on the learning that occurred as the workers decided how to integrate the technology in question (a digital patient record system) into a department’s work practices. In particular I examine how the characteristics of the technology contributed to shaping and organising t...

We present a numerical scheme for the integration of the Vlasov–Maxwell system of equations for a non-relativistic plasma, in the hybrid approximation, where the Vlasov equation is solved for the ion distribution function and the electrons are treated as a fluid. In the Ohm equation for the electric field, effects of electron inertia have been retained, in order to include the small scale dynam...

synthesis and characterization of 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-oneabstractnew 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-one (2a) was synthesized in good yield by the petrenko–kritchenko reaction of 2, 2'-((3-hydroxyp...

schiff base sal-2,5-clan = 2-(2,5-dichlorobenzylideneamino)phenol used as a new precursor for preparation of poly-2-(2,5-dichlorobenzylideneamino)phenol (pdcbap). in an aqueous alkaline medium, naocl oxidant is capable of oxidative poly-condensation reaction (op). both sal-2,5-clan and pdcbap were characterized by solubility tests, ft-ir, 1h-nmr spectroscopy and tg-dta studies. ft-ir and 1h-nmr...

background: the final objective of root canal therapy is to create a hermetic seal along the length of the root canal system. for this purpose, many methods and materials have been introduced. the purpose of this study was to compare the apical microleakage in a new obturation technique (true-tug-back) with two other obturation techniques (lateral condensation and chloroform dip technique). met...

Aim: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. Methods: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chamber bacterial model using Enterococcus ...

When the tale of Francis Knorr, baby farming murderess, went to air on ABC Radio National’s Soundproof as an experimental radio drama, it was a literal attempt parallel historical story with lived present by playing two scenes at once. This done actors performing Knorr’s and going gallows Iranian musician recording her music in exact spot where murderess hanged. These sound elements were then w...
