Science Said. Relationships between Science, Reason and Faith

Scientia et Fides, 2013
After a description of the method of mathematics and empirical sciences, brief but explicit enough to show their limits with philosophical and theological reflection, I comment the harmonic relations of mutual help among them, and also, unfortunately ...

Synthesis of zirconia colloidal dispersions by forced hydrolysis [PDF]

Journal of the Serbian Chemical Society, 2006
Different zirconia colloidal dispersions (sols) were prepared from zirconyl oxynitrate and zirconyl oxychloride solutions by forced hydrolysis. Vigorously stirred acidic solutions of these salts were refluxed at 102 oC for 24 h.

Actin reorganization at the centrosomal area and the immune synapse regulates polarized secretory traffic of multivesicular bodies in T lymphocytes

Journal of Extracellular Vesicles, 2020
T-cell receptor stimulation induces the convergence of multivesicular bodies towards the microtubule-organizing centre (MTOC) and the polarization of the MTOC to the immune synapse (IS). These events lead to exosome secretion at the IS.

Potassium limitation of forest productivity – Part 2: CASTANEA-MAESPA-K shows a reduction in photosynthesis rather than a stoichiometric limitation of tissue formation [PDF]

Biogeosciences, 2023
Potassium (K) availability constrains forest productivity. Brazilian eucalypt plantations are a good example of the K limitation of wood production. Here, we built upon a previously described model (CASTANEA-MAESPA-K) and used it to understand whether ...

Effect of Peptization on Densification and Phase-Transformation Behavior of Sol–Gel-Derived Nanostructured Titania [PDF]

, 1994
Porosity reduction, packing, pore-size distribution, and anatase to rutile phase transformation behavior of nanostructured titania ceramics prepared from both peptized and unpeptized sols were studied and compared using XRD, DSC, and nitrogen-gas ...

Electron-phonon vertex and its influence on the superconductivity of two-dimensional metals on a piezoelectric substrate [PDF]

, 2016
We investigate the interaction between the electrons of a two-dimensional metal and the acoustic phonons of an underlying piezoelectric substrate. Fundamental inequalities can be obtained from general energy arguments.
