Experimental viscosity measurements of biodiesels at high pressure [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2016
The viscosity of biodiesels of soybean and rapeseed biodiesels blended with mineral diesel fuel were measured at pressures of up to 200 MPa. Using a falling sinker-type viscometer reproducible viscosity data were obtained based on the time taken

Submerged spawning and larval dispersal of the mudskipper Periophthalmus variabilis

Aquatic Biology, 2021
Since the discovery of mudskipper aerial embryonic incubation in 1998, it has been unclear whether spawning and fertilization take place inside an air-filled or water-filled egg chamber, and whether the parent animals help the newly hatched larvae leave ...

Detection of mercury ion based on quantum dots using miniaturised optical fibre sensor

The Journal of Engineering, 2019
Mercury ion (Hg^2+) is one of the common pollutants which exists in the natural environment far and wide. The detection of Hg^2+ usually requires large laboratory equipment, which limits their field applications. Here, a miniaturised optical fibre sensor

Changements de phases durant l'électrolyse des systèmes Hg-Tl, Hg-Sn, Hg-Pb et Hg-Zn [PDF]

Journal de Physique, 1984
On utilise la méthode électrochimique de détection des transformations de phases dans les amalgames au cours d'électrolyse monotherme décrite dans un article précédent [2] pour l'étude des systèmes Hg-Tl, Hg-Sn, Hg-Pb et Hg-Zn. Dans les systèmes Hg-Pb et Hg-Zn la cristallisation se produit dès que la fraction molaire de saturation est atteinte mais des

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.
