Reversibility properties of semigroup actions on homogeneous spaces
(Springer, 2012-06-01)
This paper studies reversibility of subsemigroups acting on homogeneous spaces. The reversor set of a subsemigroup is defined and it is related to the invariant control sets for semigroups acting on certain homogeneous ...

Reversible Hamiltonian Liapunov center theorem
(2005-02-01)
We study the existence of periodic solutions in the neighbourhood of symmetric (partially) elliptic equilibria in purely reversible Hamiltonian vector fields. These are Hamiltonian vector fields with an involutory reversing ...
ANP applied to the evaluation of performance indicators of reverse logistics in footwear industry
(Elsevier B.V., 2015-01-01)
The reverse logistics (RL) seeks to facilitate the return of consumer goods, or its constituent materials, in the production cycle. The main motivators of RL are economic factors, customer service, legal, corporate citizenship ...
Practices of environmentally responsible reverse logistics systems in Brazilian companies
(2013)
The aim of this paper is to propose a classification of reverse logistics systems based on activities for value recovery from returned products. Case studies were carried out in three Brazilian companies. Research results ...
Phase portraits of reversible linear differential systems with cubic homogeneous polynomial nonlinearities having a non-degenerate center at the origin
(2009-12-01)
In this paper we classify the global phase portraits of all reversible linear differential systems with cubic homogeneous polynomial nonlinearities defined in the plane and having a non degenerate center at the origin. The ...
On the reversible quadratic polynomial vector fields on S-2
(Academic Press Inc. Elsevier B.V., 2012-12-15)
We study a class of quadratic reversible polynomial vector fields on 52 with (3, 2)-type reversibility. We classify all isolated singularities and we prove the nonexistence of limit cycles for this class. Our study provides ...

Bilateral reversed palmaris longus muscle: a rare anatomical variation
(VIA MEDICA, 2012)
We report a case of bilateral reversed palmaris longus muscle (PLM). The muscle was tendinous in its upper portion and muscular in its lower portion in both arms. This rare variation has been mentioned only once in the ...
