Bicyclic graphs with maximum sum of the two largest Laplacian eigenvalues

open access: yesJournal of Inequalities and Applications, 2016
Let G be a simple connected graph and S 2 ( G ) $S_{2}(G)$ be the sum of the two largest Laplacian eigenvalues of G. In this paper, we determine the bicyclic graph with maximum S 2 ( G ) $S_{2}(G)$ among all bicyclic graphs of order n, which confirms the

Bicycling to university: evaluation of a bicycle-sharing program in Spain [PDF]

open access: yesHealth Promotion International, 2013
This study examined the change in behavioral stages (e.g. contemplation, action and maintenance) of cycling to university before and after the implementation of a new public bicycle share program (PBSP) and promotion of its use. The study also determined the change in the prevalence, correlates of PBSP use and potential role in the promotion of healthy
