The technique starts with merging the cover image and the watermark image with suitable ratios, i.e., 99% from the cover image will be merged ...

OBJECTIVE To study the effect of three energy drinks on the color stability of nanofilled composite resins after different periods of aging time. MATERIALS AND METHODS Composite resin disks, 6 mm diameter, 3 mm thickness were prepared from Filtec Z350 XT, Tetric EvoCeram, and Filtec Z250 XT. Specimens from each material were tested after aging with Red Bull, Bison and Power Horse energy drink...

Individual indices of spectral analysis (SA) of heart rate variability (HRV), which are used to diagnose the autonomic nervous system (ANS) activity, often give somewhat inconclusive and antagonistic results. Based on the results of age dependence (Šlachta et al., 2002), and dependence of exercise intensity (Stejskal et al., 2001) on the short-term SA HRV, the authors developed a new evaluation...

In the Mediterranean Sea, the distribution of dissolved zinc, copper, lead and cadmium is primarily controlled by marine circulation, surface source dynamics and biological new production. We show that the present relatively high content of these metals in the surface layer is due to non-steady-state cycles as a result of source increases probably following increases in industrial, agricultural...

The Haouz aquifer is undergoing climatic aridity and anthropic pressure largely related to the agricultural sector. In this study, special attention was given main factors that have a direct impact on fluctuations of piezometric level (PL). Different statistical analyses (cross-correlations, PCA, cascading analysis) relationship between these were applied here. results identify three distinct g...
