Background/purpose: En masse retraction was still controversy in orthodontics.The aim of this study was to investigate the effect of force directions created by different miniscrew positions and lever arm heights on maxillary central incisor movement using Finite Element (FE) simulation and a Typodont model.Materials and methods: A typodont model a

The purpose of this study was to design and test an intelligent computer software developed with the purpose of increasing average productivity of milling not compromising the design features of the final product.The developed system generates optimal milling parameters based on the extent of tool wear.The introduced optimisation algorithm employs

The first application of laparoscopic liver surgery consisted of wedge liver biopsies or resection of peripheral lesions, mostly benign.More recently, reports of anatomic left and right hepatectomy have been seen in the literature.Expertise in some centers has evolved to such an extent that even living related donor hepatectomy has been performed.T

A variety of potential applications such as visible light communications require laser sources with a narrow linewidth and VR Cases a single wavelength emission in the blue light region.The gallium nitride (GaN)-based distributed feedback laser diode (DFB-LD) is a promising light source that meets these requirements.Here, we present GaN DFB-LDs tha

Australia has one of the highest asthma prevalence rates in the world, with this chronic and debilitating condition affecting one in nine people.The health and mental wellbeing of young people with asthma are worse than not only their peers without asthma but also worse than that of people with asthma at other ages.Psychological interventions could
