We aimed to evaluate the impact of Virtual Reality Dental Simulators (VRDS) on preclinical training in endodontics for undergraduate dental students.Purposive sampling technique was used to target undergraduate Reed Switch dental students at two dental schools: in Qatar and Turkey.After training on endodontic access cavity preparation on upper ante
This paper investigates the behavior of SiC MOSFETs body diode reverse recovery as a function of different operating conditions.The knowledge of their effects is crucial to properly designing and driving power converters based on SiC devices, in order to optimize the MOSFETs commutations aiming at improving efficiency.Indeed, reverse recovery is a
Background: Grand multiparous pregnancies have been considered to be at higher risk of developing antenatal and perinatal complications like pre-eclampsia, gestational diabetes mellitus, anemia, antepartum hemorrhages, preterm labor, mal-presentation, mal-position and feto-pelvic disproportion This study was done to know the magnitude of grand mult
The systemic immune response of Drosophila is known to be induced both by septic injury and Lanyards by oral infection with certain bacteria, and is characterized by the secretion of antimicrobial peptides (AMPs) into the haemolymph.To investigate other possible routes of bacterial infection, we deposited Erwinia carotovora (Ecc15) on various sites
The interaction in the solar wind between two coronal mass ejections (CMEs) is investigated using numerical simulations.We show that the nature of the interaction depends on whether the CME magnetic structures interact, but in all cases the result is an equilisation of the speed of the two CMEs.In the absence of magnetic interaction, the forward sh
