The electrochemistry of 3-alkoxy- and 3-hydroxy-1-[omega-(dialkylamino)alkyl]-5-nitroindazole derivatives were characterized using cyclic voltammetry in DMSO. The nitro reduction process was studied and this was affected by the acid moieties present in these compounds. A nitro anion self-protonation process was observed. This phenomenon was studied by cyclic voltammetry in presence of increasin...

The effects of ultrasound on 2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonate) enzymatic oxidation by laccase (Trametes villosa) has been studied by means of cyclic voltammetry. The reaction was allowed to proceed in the presence of a piece of wool and the coloration depth of the wool fabric was measured by means of K/S. It was observed that cyclic voltammetry is influenced the dyeing process a...

Photosynthesis is the biological process that feeds the biosphere with reduced carbon. The assimilation of CO2 requires the fine tuning of two co-existing functional modes: linear electron flow, which provides NADPH and ATP, and cyclic electron flow, which only sustains ATP synthesis. Although the importance of this fine tuning is appreciated, its mechanism remains equivocal. Here we show that ...

Basic approaches of mobile cyber-physical systems (CPS) such like cars, trains, aeroplanes or spaceships are parts of our daily life. Mobile CPSs are embedded into a physical environment which is usually harsh and uncertain. Monitoring mobile CPSs is essential to ensure reliability and to avoid damage. Monitoring mobile CPSs presupposes knowledge about the CPS, the physical environment and the ...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

A unique process for regenerating calcium-based sorbents which are in the form of calcium sulfide was demonstrated by employing thermogravimetric analysis (TGA). The process converts calcium sulfide to calcium oxide by subjecting particles of the material to repeated cycles of oxidation and reduction at temperatures between 950 and 1100 °C. During each cycle a small portion of material is first...
