The electrochemical reduction of perchloroethylene (PCE) in water has been analyzed through voltammetric studies with a
rotating disc electrode and controlled potential bulk electrolysis. The influence of the mass transport conditions and initial concentration on lead, copper and carbon electrodes…

Drawing partly on personal experience, the author of this article seeks to unpack the expertise that service users bring to the design and delivery of mental health services. Service user involvement cannot be imposed by policy diktat from above, she…

Electrocrystallization of PbO2 on glassy carbon electrodes was studied in 1 M HNO3 + 0.1 M Pb(NO3)2 using cyclic voltammetry rotating disk electrode experiments, chronoamperometry, and scanning electron microscopy. In order to explain the experimental curves, a new theory of…

We studied the phylogeny and systematics of the tribe Paragini (Diptera: Syrphidae) using morphological and molecular data. The paper presents separate parsimony analyses of both adult morphological characters and partial DNA sequence data from mitochondrial cytochrome c oxidase I and…

The kinetics of activation and inactivation in the phototransduction pathway of developing
Xenopus
rods were studied. The gain of the activation steps in transduction (amplification) increased and photoresponses
became more rapid as the rods matured from the larval to the…
