The composition dependence of the surface tension of highly nonideal organic-organic and aqueous-organic nonelectrolyte solutions is described, based on the assumption that the surface layer can be treated as a separate phase located between vapor and bulk liquid phases. The Wilson, NRTL, and UNIFAC methods are used for activity coefficients of surface and bulk phases and three techniques for c...
The aim of the present study is to evaluate the effect of voluntary wheel running on striatal dopamine level and behavior of cognition and emotion in molar loss rats. Twenty-four Sprague-Dawley rats were enrolled in this study and randomly divided into following 4 groups: control group (C group), molar loss group (ML group), 1-week physical exercise before molar loss group (1W-ML group), and 4-...
Knowledge space theory was used for mapping students’ knowledge structures in calculating density, mass-percent, molar mass and molar volume. Data were collected among the 9-10 graders (age 15-16) at two different secondary grammar schools. Students’ responses were evaluated in a binary fashion and were used for determining knowledge structures with a systematic trial-and-error process using χ ...
The aim of this study was to describe the replantation of a maxillary second right molar, which had been removed for surgical reasons in order to remove a dentigerous cyst associated with the adjacent third molar, and the case's 12-month follow-up. A 51-year-old man presented swelling in the right maxillary area. Radiographic examination showed a large radiolucency in close proximity to the thi...
autogenous tooth transplantation (att) can be considered when there is a hopeless molar tooth and suitable donor present. this report presents an unconventional case of successful att of a third molar replacing the adjacent fractured second molar in a 33 year old woman. this wisdom tooth had completely developed roots. root-end filling with calcium enriched mixture (cem) cement was performed in...
objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...
tooth transplantation can be considered a valid and predictable treatment option for rehabilitating young patients with permanent teeth loss. this study presents several cases of successful autogenous tooth transplantation with a 6-9 months follow-up. tooth auto-transplantation can be considered a reasonable option for replacing missing teeth when a donor tooth is available. the auto-transplant...
