The Correlation between Body Mass Index, Protein Intake, and Quality of Life in Elderly [PDF]

open access: yesInternational 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

Some exactly solvable three-body problems in one-dimension [PDF]

open access: yes, 1993
The three-body problem in one dimension with a repulsive inverse-square potential between every pair was solved by Calogero. After mapping the three-body problem to that of a particle on a plane, the known results of supersymmetric quantum mechanics are ...

Algebraic Treatment of Three-Body Problems [PDF]

open access: yes, 1997
. We discuss an algebraic treatment of three-body systems in terms of a (7) spectrum-generating algebra. In particular, we develop the formalism for nonlinear configurations and present an algebraic description of vibrational and rotational excitations ...

BURRAU'S PROBLEM OF THREE BODIES [PDF]

open access: yesProceedings of the National Academy of Sciences, 1967
initially. The problem treated in this paper is to determine their subsequent motion. Because of the relation of the initial conditions to a Pythagoreani triangle, Burrau's problem may also be referred to as a Pythagorean problem of three bodies. That the motion of the particles takes place in the plane of the triangle is an immediate consequence of ...

A new hybrid finite element approach for three-dimensional elastic problems

open access: yesArchives of Mechanics, 2012
A new fundamental solution based finite element method (HFS-FEM) is presented for analyzing three-dimensional (3D) elastic problems with body forces in this paper. It begins with deriving formulations of 3D HFS-FEM for elastic problems without body force

On a Periodic Solution of the 4-Body Problems

open access: yesAdvances in Mathematical Physics, 2014
We study the necessary and sufficient conditions on the masses for the periodic solution of planar 4-body problems, where three particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.
