Introduction: The measurement precision of jaw is important for surgery or installing implants. Preimplant radiographs are important part of clinical evaluations before implant surgery. For choosing location, we should consider the important anatomical structures like mental foramen, inferior alveolar canal, nasal cavity and maxillary sinus.It is important to know the measurement accuracy of ra...
Liquid flowing through a thin-walled "collapsible" tube similar to a vein, inclined to any angle between vertical and slightly above horizontal, differs from the flow in rigid tubes in that: a "collapsible" tube accepts any flow presented to it without affecting the rate of flow through the system; the lateral pressure at all cross sections throughout the tube is zero and does not change as the...
Abstract An analysis into the transient natural convective flow of a nanofluid in vertical tube is made. The governing equations momentum, heat transfer and nanoparticle volume fraction are deduced, influence thermophoresis parameter Brownian motion incorporated. By direct integration variation parameter, analytical solutions obtained for formation heat/mass at steady-state. On other hand, due ...
