The present study evaluated the skeletal alterations induced by rapid maxillary expansion procedures in 30 patients in the primary and mixed dentitions. The results were obtained with the use of lateral cephalometrics before and immediately after the active phase of expansion. The time span between these two cephalometric films ranged from 14 to 21 days;(More)
Methods Rheology Discovery DHR-2 rotational rheometer (TA Instruments, USA) was used for investigation of rheological properties of the solutions under steady-state shear deformation. Cone-plate geometry with diameter of 40 mm and the angle at cone tip of 1° was applied. All tests have been carried out at 23 °C. HRSEM and cryo-HRSEM A single fiber was(More)
Fibers were electrospun from a solution comprised of oppositely charged polyelectrolytes, in efforts to achieve highly confined macromolecular packaging. A stoichiometric ratio of poly(allylamine hydrochloride) and poly(acrylic acid) solution was mixed in an ethanol-water co-solvent. Differential scanning calorimetry (DSC) analysis of electrospun fibers(More)
