We prove that, for each nonnegative integer k and each matroid N, if M is a 3-connected matroid containing N as a minor, and the the branch width of M is sufficiently large, then there is a k-element subset X of E(M) such that one of M\X and M/X is 3-connected and conta...

The temporal dynamics of the oxygen uptake (V˙O2) during moderate exercise has classically been related to physical fitness and a slower V˙O2 dynamics was associated with deterioration of physical health. However, methods that better characterize the aerobic system temp...

Sediment Quality Guidelines (SQG) that do not account for biomagnification of chemicals in marine food chains, may be insufficiently protective of upper trophic level organisms. Biota-Sediment Accumulation Factors (BSAF=Cbiota/Csediment) quantify the relationship betwee...

Thank you to: - Roger Nkambou, my research director and Jacqueline Bourdeau, my research co-director, for their availability and their support during my PhD. They are both professors at Université du Québec à Montréal. - Riichiro Mizoguchi, professor at the Institute of...

My special thanks go to my research director, Mr Roger Nkambou, professor in the department of computer science at UQÀM, and my research co-director, Ms Jacqueline Bourdeau, professor at the Télé-Université. As well, I especially thank Professor Froduald Kabanza, Dr. Je...

We study the following problem for critical site percolation on the triangular lattice. Let $A$ and $B$ be sites on a horizontal line $e$ separated by distance $n$. Consider, in the half-plane above $e$, the lowest occupied crossing $R_n$ from the half-line left of $A$ ...

This paper summarizes the published information on the beetle fauna of the island of Martinique, in the Lesser Antilles. The fauna is known to contain 42 families, with 201 genera, and 270 species. The families with the largest numbers of species are Cerambycidae (57), ...
