Biodiesel production by transesterification in two steps: Kinetic effect or shift in the equilibrium conversion?
(Elsevier Science, 2018-12)
In continuous biodiesel production plants, practically all technologies carry out the transesterification in two steps, feeding methanol and catalyst in each of them. The glycerine phase is separated after the first one. ...
Synthesis and morphological characterization of nanoporous aluminum oxide films by using a single anodization step
(MDPI, 2019-02)
Nanoporous anodic aluminum oxide (AAO) films play an important role in nanotechnology due to their easily adjustable morphological properties and wide range of applications. Thus, a deep and systematic characterization of ...

A Robust Two-Step Inversion of Complex Magnetotelluric Apparent Resistivity Data
(Springer Verlag, 2005)
Though two-dimensional inversion is now a standard procedure, interpretation of magnetotelluric (MT) data under the assumption of isotropic and one-dimensional structures is a valuable procedure for a first step interpretation ...
Effects of square-stepping exercise on cognitive functions of older people
(2013-09-01)
Aim: Cognitive functions can decline with age, and interventions focusing on stimulating them may have positive results. Previous studies have shown that square-stepping exercise (SSE) has a good influence on balance, but ...
