Several papers have been published on the monitoring of environmental conditions inside museums and galleries. There are also some works regarding air quality in churches, which are relevant for cultural heritage (CH). Historical buildings and castles, that have nowadays been turned into museums, where precious CH items are exhibited, should be studied as well. However, in such historical build...

Laparoscopic vessel sealing devices have revolutionized modern laparoscopy. These devices fall into 2 major categories: advanced bipolar and ultrasonic instruments. The range of tissue effects available with these technologies is more limited than with conventional monopolar electrosurgery; however, both advanced bipolar and ultrasonic devices efficiently seal vessels (≤7-mm and ≤5-mm diameter,...

Data sealing is a cryptographic problem between two parties. A sender (Alice) stores some secret data in a certain form, so that any other reader (Bob) can read it without Alice’s helping. Meanwhile, if the data has been read, it should be detectable by Alice[1]. A common example of classical data sealing is closing a letter in an envelop with a wafer of molten wax, into which was pressed the d...

Introduction: Sealing ability of a retrograde filling material is an important factor for a successful endodontic apicoectomy. The purpose of this in-vitro study was to compare the sealing ability of calcium enriched mixture (CEM) cement versus amalgam as root-end filling materials. Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and obturated using later...
