The main goal of the present paper is to study the lifetime of orbits around moons that are in elliptic motion around their parent planet. The lifetime of the orbits is defined as the time the orbit stays in orbit around ...

Objective: The objective of the study was to compare the functional and aesthetic results of fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer. Materials and Methods: ...

In this paper we present an analytical theory with numerical simulations to study the orbital motion of lunar artificial satellites. We consider the problem of an artificial satellite perturbed by the non-uniform distribution ...

Low-altitude, near-polar orbits are very desirable for scientific missions to study the natural satellites of the planets of the Solar System, such as Europa, that is one of the natural satellites of Jupiter. The problem ...

Purpose: The goal of orbital reconstruction is to restore anatomy, volume, and function. In extensive orbital floor defects, the visualization of the posterior area is limited through inferior eyelid incisions. The use of ...

Introduction: The aim of the study was to describe the normal orbital volume and its most important relationships with other clinical variables. Methods: We designed a correlation study and consecutive normal CTs scans ...
