Abstract The aim of this study was to assess the effect phytic acid and compare it with phosphoric etching through a systematic review. search carried out using PubMed/MEDLINE, Cochrane library, Indmed, Scopus, Liliacs databases conducted upto January 2022. In vitro studies comparing as an etchant on tooth surfaces that performed bond strength, smear layer removal, collagen degradation monomer ...

Macro- and microscale metallic glasses exhibit excellent protective capability under hypervelocity projectile impact conditions. However, it is formidably challenging to evaluate the ballistic performance of with characteristic sizes down nanoscale. Here, we adopt laser-induced micro-particle technique penetrate 60-nm-thick Ni60Ta40 glass nanofilms velocities in range 186–540 m/s. Based on anal...

The first signs of mobile commerce hype are here. Extremely rapid penetration and growth processes are predicted on the basis of some quick descriptions of mobile technology. The roots of these predictions are often found in markets with a low penetration rate of mobile technology. Nevertheless, it should be clear that without real substance in m-commerce products and services the investments i...

This paper gives an overview on the potentials of numerical simulations for understanding dynamics in laser material processing. After a short introduction into the model, simulation results on several processes like laser beam deep penetration welding, drilling or cutting are presented. Furthermore simulation results are compared with experimentally obtained data.

This paper analyzes the impact on mobile telephony diffusion patterns of the two predominant payment regimes, calling party pays (CPP) and receiving party pays (RPP), for mobile termination services. By applying instrumental variable techniques to panel data we account for a possible interdependency of penetration rates and regulatory interventions. For this purpose we use data on political and...
