background : composite resin restorations may have a short lifespan due to the degradation of resin–dentin interface. ethanol wet bonding technique may extend the longevity of resin–dentin bond. the purpose of this one year randomized clinical trial was to compare clinical performance of two adhesives with ethanol wet bonding technique. materials and methods: this randomized clinical trial was ...

In this paper, the bonding, relative stabilities and local ionic charges occurring in sodium chloride nanotubes are discussed. A new methodology is introduced which employs a linear relationship between nanotube cohesive energies determined via Density Functional Theory (DFT) and weighted-average Madelung Constants (MC(wa)). The slope of the linear plots reveals ionic charges and gives insights...

Imperfect recall games remain an unexplored part of the game theory, even though recent results in abstraction algorithms show that the imperfect recall might be the key to solving the immense games found in the real world efficiently. Our research objective is to develop the first algorithm capable of outperforming the state-of-the-art solvers applied directly to perfect recall games, by creat...

Background Emotional bonding between mother and neonate is an extremely sensitive process in postpartum. Therefore, one of the important processes in the postpartum period is the development of maternal and neonatal bonding. This study was aimed to investigate the effect of family-based counseling on mother-child bonding at 4-6 weeks of postpartum in women referred to selected health centers of...

the aim of the present study was to examine the casual relationship of parental bonding with bullying in schools, mediated bypersonality characteristics and student-teacher relationship quality. 200 second-grade male high-school students in ahvaz were selected using multi-stage random sampling method. the data were collected by the parental bonding instrument (pbi), neo-personality inventory-re...

Background and Aim: One of the important factors in microleakage of fissure sealants is saliva contamination. Researchers believe that applying bonding agents can reduce the microleakage. The present study compared the microleakage of a fissure sealant contaminated with artificial saliva at different curing times with or without using a bonding agent. Materials and Methods: In this in-vitro ...
