In the study of the fundamental theory and the characterizations of space curves, the related curves for which there exist corresponding relations between the curves are very interesting and important problems. The most fascinating examples of such curve are associated curves, the curves for which at the corresponding points of them one of the Frenet vectors of a curve coincides with the one of...

Simple fixed bed models such as the Bohart–Adams and Thomas equations are often used to describe breakthrough characteristics of water air contaminant adsorption in adsorbers. However, these popular confined correlating highly symmetric curves. The present study explores feasibility using two probability distributions (normal log-normal) track asymmetric curves for columns (ciprofloxacin, ammon...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...
