objective: since orthodontic and orthognathic treatment planningin each ethnic group must be done according to the soft tissue facial characteristicsregarded as beauty,they thus vary from country to country.the main purpose of this articlewas to determine the mean range of the middle third of soft tissue facial profile and anteroposterior lip positioningusing 3angular and 2 linear measurements ...

It is well-known that internal waves can propagate downwards in the interior of the oceanic (e.g. Gill, 1982) and this process has been studied experimentally in the laboratory (e.g. Stevens and Imberger, 1994). Moreover, it is well-known that a monochromatic internal wave is an exact solution of the fully nonlinear Euler equations for a stratified fluid (in the Boussinesq approximation) with a...

Abstract Understanding the transport mechanism of electronic excitations in conjugated polymers is key to advancing organic optoelectronic applications, such as solar cells, light-emitting diodes and flexible electronics. While crystalline can be studied using solid-state techniques based on lattice periodicity, characterisation amorphous hindered by an intermediate regime disorder associated l...
