Nowadays digital watermarking has become an important technique, because using computational tools, digital contents can be copied and/or modified easily. At the beginning, the digital watermarking has been used for either copyright protection purpose or content authentication purpose. However, in many situations both purposes (copyright protection and content authentication) are required to be...

In the performance of a transvascular liver biopsy, the Trucut-type transjugular liver biopsy set is advance over a multipurpose catheter place in the suprahepatic vein. Occasionally there is a sharp bend between the suprahepatic veins and the inferior vein cava and the multipurpose catheter does not provide sufficient support to track the biopsy access set. To deal with this problem we describ...

Background Immediate dentin sealing implies applying an adhesive system to directly after tooth preparation, before impression. The technique is universal (inlays, onlays, veneers, crowns) and well documented clinically experimentally. Different types of bonding agents (DBAs) are available on the market. Major differences lie in thickness hybrid layer overlaying resin (filled vs. unfilled/light...

The aim of this paper is to study the integration of multiplicative preference relation as a preference representation structure in fuzzy multipurpose decision-making problems. Assuming fuzzy multipurpose decision-making problems under di4erent preference representation structures (ordering, utilities and fuzzy preference relations) and using the fuzzy preference relations as uniform representa...

Aim. The aim of this study is to evaluate the shear bond strength of nanocomposite to stainless steel crowns using a new universal bonding system. Material and Methods. Eighty (80) stainless steel crowns (SSCs) were divided into four groups (20 each). Packable nanocomposite was bonded to the lingual surface of the crowns in the following methods: Group A without adhesive (control group), Group ...

It was the aim of the current in vitro study to test the erosion-preventive potential of an experimental surface sealant (K-0184) and currently marketed self-etch adhesive systems under abrasive conditions. Ninety-six dentine specimens were randomly allocated to eight groups (n=12): (1) positive control (no treatment), (2) K-0184, (3) Shield Force Plus, (4) Xeno Select, (5) Scotchbond Universal...

In this study, a 35% phosphoric acid gel (3M Scotchbond etchant), a nonrinse etchant (NRC), and two EDTA-containing conditioners (RC-Prep and File-Eze) were tested in vitro for blocking nerve conductance evoked in the rat sciatic nerve after local application. The phosphoric acid gel and NRC completely and irreversibly inhibited conductance. On the other hand, RC-Prep reduced the compound actio...
