this study is aimed to evaluate the effect of covering exposed root surface by collagen membrane and to compare this method with coronoally advanced flap covering. 26 teeth in 20 patients (12m/8f) with miller1 gingival recession were selected. 14 teeth were allocated into test group and 12 teeth in control group. following first phase of treatment, clinical parameters including the height and w...

This work aims at proposing a novel approach to classify acoustic emission (AE) signals deriving from corrosion damage, even if embedded into a noisy environment. Tests involving noise and crevice corrosion are conducted, by preprocessing the waveforms including wavelet denoising and extracting a rich set of features as input of the Random Forest algorithm. To this end, a software called RF-CAM...

A comparative study on the mechanical properties, scratch resistance, and localized corrosion (pitting crevice) of plasma-nitrided Inconel alloy 718 (UNS NO7718: IN 718) was carried out. Thermochemical treatment performed at low temperatures (400 450 °C) for 4 h. The formed layers with thicknesses 7.17 ± 0.89 µm 7.96 0.48 (450 °C). XRD nanohardness analyses indicated formation a hard layer comp...
