abstract statement of problem: there is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. objectives: to evaluate the shear bond strength of 2 different adhesives (one resin modified glass ionomer and one resin) using two caries removal techniques on healthy and car...

The effect of the embedding medium on the nano-indentation measurements of lignocellulosic materi­ als was investigated experimentally using nano-indentation. Both the reduced elastic modulus and the hardness of non­ embedded cell walls were found to be lower than those of the embedded samples, proving that the embedding medium used for specimen preparation on cellulosic material dur­ ing nano-...

With the progress of technology, virtual reality technology plays a key role in many domains and has great potential and applied prospects. Virtual campus is the reappearance of a real campus’s scene by applying virtual reality technology. This technology is aimed to the construction and propaganda of campus. But in the course of construction of the three-dimensional virtual campus scene, owing...
