Coloca também o problema da operatividade da história, tal como Portas e Vieira de Almeida o estavam a fazer, sem escamotear o problema da instrumentalização: "Metodologicamente,

The fi lms were also studied by spectroscopic techniques (photoluminescence, FTIR, and UV e VIS), and it was veri fi ed that the values of n decrease with increasing the amount of C ]

Raman spectra allowed us to identify the symmetry groups of the samples: samples with Yb, Y and Ho are cubic and presented 4 intense Raman bands; ceramics with Dy, Tb, Gd and Eu

In order to investigate that, we carried out Raman spectroscopic measurements in all BYN ceramics aiming to analyze the evolution of the phonon modes, probing potential

Indeed, the modi fi cation of the chemical structure of the scavenger due to reaction with free radicals induced by the blue- light irradiation is also observed in the 0 e 6 ppm

Intermittent catheterisation with hydrophilic-coated catheters (SpeediCath) reduces the risk of clinical urinary tract infection in spinal cord injured patients: a

Detailed optical properties were evaluated using UV-Vis spectroscopy, and photoluminescence (PL) emission spectra of doped and undoped CT were employed to examine the
