UNLABELLED The presence of porosities at the dentin/adhesive interface has been observed with the use of new generation dentin bonding systems. These porosities tend to contradict the concept that etching and hybridization processes occur equally and simultaneously. Therefore, the aim of this study was to evaluate the micromechanical behavior of the hybrid layer (HL) with voids based on a self-...

With the emerging concept of model transformation, information can be extracted from one or more source models to produce the target models. The conversion of these models can be done automatically with specific transformation languages. This conversion requires mapping between both models with the help of dynamic hash tables. Hash tables store reference links between the elements of the source...

Composite propellers offer high damping characteristics and corrosion resistance when compared with metal propellers. But the design of a hybrid composite propeller with the same strength of metal propeller is the critical task. For this purpose, the present paper focusses on fluid-structure interaction analysis of hybrid composite propeller with Carbon/Epoxy, R-Glass/Epoxy and S2-Glass/Epoxy t...

When the police have no suspect, they may ask an eyewitness to construct a facial composite of that suspect from memory. Faces are primarily processed holistically, and recently developed computerized holistic facial composite systems (e.g., EFIT-V) have been designed to match these processes. The reported research compared children aged 6-11 years with adults on their ability to construct a re...

objective: various techniques of composite placement have been used to decrease microleakage around the composite restorations. due to controversial results, the present study was conducted to investigate the effect of different placement techniques on microleakage in class v composite restorations. materials and methods: sixty class v cavities were prepared on the buccal and lingual surfaces o...

objective: different methods have been suggested to overcome the polymerization shrinkage of composite restorations. changing the light curing protocol to improve polymerization by using new light curing units is among these methods. the new devices are more efficient, portable and durable and produce less heat. this study aimed to assess the marginal microleakage of class v composite restorati...
