Rapeseed oil‑rich diet alters hepatic mitochondrial membrane lipid composition ...

Diet is directly related with physiological alterations occurring at a cell and subcellular level. However, the role of diet manipulation on mitochondrial physiology is still largely unexplored. Aiming at correlating diet with alterations of mitochondrial membrane composition and bioenergetics, Wistar-Han male rats were fed for 11, 22 and 33 days with a rapeseed oil-based diet and mitochondrial bioenergetics, a...

Effect of fiber orientation in gelled poly (vinylience fluoride) electrospun me...

Battery separators based on electrospun membranes of poly(vinylidene fluoride) (PVDF) have been prepared in order to study the effect of fiber alignment on the performance and characteristics of the membrane. The prepared membranes show an average fiber diameter of ~272 nm and a degree of porosity of ~87 %. The gel polymer electrolytes are prepared by soaking the membranes in the electrolyte solution. The align...

Flow cytometric method for cell viability evaluation of Gordonia alkanivorans s...

This work reports the development of a rapid flow cytometric method for the viability assessment of Gordonia alkanivorans strain 1B, a bacterium used in the biodesulfurization process. To demonstrate that it is possible to monitor by flow cytometric analysis changes in this bacterium physiological state, positive controls using the 5(6)-carboxyfluorescein diacetate (CFDA) and propidium iodide (PI) staining mixt...

Flow cytometric method for cell viability evaluation of Gordonia alkanivorans s...

The most commonly method used for sulfur removal from fossil fuels is hydrodesulfurization, a physico-chemical process at very high temperatures and pressures. An alternative to this process is biodedesulfurization (BDS), a microbiological process that works at atmospheric pressure and temperature making it easier to work with and less expensive. It also as the advantage of easily desulfurizing recalcitrant sul...

Assessing cell polarity reversal degradation phenomena in PEM fuel cells by ele...

Electrochemical impedance spectroscopy (EIS) is identified as one of the most promising in-situ diagnostics tools available for assessing fuel cell ageing and degradation. In this work, the degradation phenomena caused by cell polarity reversal due to fuel starvation of an open cathode 16 membrane electrode assembly (MEA) – low power (PEM) fuel cell (15 W nominal power) – is reported using EIS as a base techni...

Rheological properties of alkaline activated fly ash used in jet grouting appli...

The application of alkaline activated fly ash to soil stabilisation has been recently studied, and although the structural behaviour was adequate, some concerns were raised regarding its apparent viscosity, which proved to be an important issue in jet grouting applications. Therefore, this paper deals with the experimental study of rheology of alkaline activated fly ash-based grouts, namely with: setting time o...
