IMMEDIATE SKELETAL EFFECTS OF RAPID MAXILLARY EXPANSION AT MIDPALATAL SUTURE OPENING WITH DIFFERENTIAL, HYRAX AND HAAS EXPANDERS

Immediate skeletal effects of rapid maxillary expansion at midpalatal suture opening with Differential, Hyrax and Haas expanders

ABSTRACT Objective: The aim of this study was to test the null hypothesis that there is no difference at the midpalatal suture opening after rapid maxillary expansion (RME) using Expander with Differential Opening (EDO), Hyrax-type and Haas-type expanders.Methods: Occlusal radiographs of 52 patients (19 males and 33 females; average age= 9.46?1.20

A Hybrid-Surrogate-Calibration-Assisted Multi-Fidelity Modeling Approach and Its Application in Strength Prediction for Underwater Gliders

Multi-fidelity surrogate-based methods play an important role in modern engineering design applications, aiming to improve model accuracy while reducing computational cost.One of the widely adopted approaches is the calibration-based method, which calibrates the low-fidelity model through mr robot funko a discrepancy model between low-fidelity and

Effect of CeO2, TiO2 and SiO2 nanoparticles on the growth and quality of model medicinal plant Salvia miltiorrhiza by acting on soil microenvironment

In this study, a six-month pot experiment was conducted to explore the effects of nanoparticles (NPs), including CeO2, TiO2 and SiO2 NPs at 200 and 800 mg/kg, on the growth and quality of model medicinal plant Salvia miltiorrhiza.A control group was implemented without the application of NPs.Results showed that NPs had no significant effect on root
