Determination of silicate liquid thermal expansivity using dilatometry and calorimetry [PDF]

open access: yes, 1992
A method for the determination of relaxed silicate liquid molar volume and expansivity at temperatures just above the glass transition is discussed. The method involves the comparison of heat capacity and molar expansivity in the glass transition region.

The evaluation of occlusal relationship between the primary canines and primary molars in 3 to 5-year-old Iranian children [PDF]

open access: yesJournal of Dental Materials and Techniques, 2017
Aim: As to the assessment of occlusal status pertaining to primary canines and molars, the latter is less within reach as it is difficult to guide jaws towards a centric occlusion while maintaining a vintage point in both direct and indirect observation.
