New periodic orbits in the solar sail three-body problem [PDF]
, 2011 We identify displaced periodic orbits in the circular restricted three-body problem, wher the third (small) body is a solar sail. In particular, we consider solar sail orbits in the earth-sun system which are high above the exliptic plane.

Solar sail equilibria in the elliptical restricted three-body problem [PDF]
, 2006 The existence and dynamical properties of artificial equilibria for solar sails in the elliptical restricted threebody problem is investigated.We show that planar two-dimensional equilibrium curves exist, embedded in threedimensional space, in a ...

Artificial three-body equilibria for hybrid low-thrust propulsion [PDF]
, 2008 This paper proposes a new concept of creating artificial equilibrium points in the circular restricted three body problem, where the third body uses a hybrid of solar sail and solar electric propulsion.

Low thrust propulsion in a coplanar circular restricted four body problem [PDF]
, 2012 This paper formulates a circular restricted four body problem (CRFBP), where the three primaries are set in the stable Lagrangian equilateral triangle configuration and the fourth body is massless.

New periodic orbits in the solar sail restricted three body problem [PDF]
, 2008 In this paper we consider periodic orbits of a solar sail in the Earth-Sun restricted three-body problem. In particular, we consider orbits which are high above the ecliptic plane, in contrast to the classical Halo orbits about the collinear equilibria ...

Cylindrical Manifolds and Tube Dynamics in the Restricted Three-Body Problem [PDF]
, 2004 Within the phase space of the planar circular restricted three-body problem, stable and unstable manifolds of periodic orbits with a S x R (cylindrical) geometry are shown to exist.

The Correlation between Body Mass Index, Protein Intake, and Quality of Life in Elderly [PDF]
International Journal of Nutrition Sciences, 2019 Background: The elderly is an age group that is susceptible to nutritional problems, especially protein intake which tends to be less intake, so it affects the body mass index. Both of these problems directly or indirectly will also affect the quality of
