The development of foils for racing boats has changed the strategy of ***,the America's cup held in San Francisco,has been the theatre of a tragicomic history due to the foils. During the last round,the New-Zealand boat was winning by 8 to1 against the defender USA. The winner is the first with 9 victories. USA team understood suddenly(may be) how to use the control of the pitching of the main foils by adjusting the rake in order to stabilize the ship. And USA won by 9 victories against 8 to the challenger NZ. The goal in this paper is to point out few aspects which could be taken into account in order to improve this mysterious control law which is known as the key of the victory of the USA team. There are certainly many reasons and in particular the cleverness of the sailors and of all the engineering team behind this project. But it appears interesting to have a mathematical discussion,even if it is a partial one,on the mechanical behaviour of these extraordinary sailing boats. The numerical examples given here are not the true *** have just been invented in order to explain the theoretical developments concerning three points: The possibility of tacking on the foils for sailing upwind,the nature of foiling instabilities,if there are,when the boat is flying and the control laws.

Thallium is a heavy metal highly toxic to the biosphere. It can be determined by anodic stripping voltammetry after deposition on mercury film. The aim of this work is to study the conditions and mechanisms of deposition of Hg on glassy carbon electrode and Tl on Hg film by cyclic voltammetry, scanning electron microscopy, chronoamperometry and impedance techniques. The results showed a germination and growth of a 3D Hg phase on glassy carbon electrode. Similarly, the electrodeposition of Tl on Hg follows a 3D three-dimensional nucleation with diffusion controlled growth. The impedance measurements reveal an easier charge transfer on the Tl film.

The HP model for protein structure prediction abstracts the fact that hydrophobicity is a dominant force in the protein folding process. This challenging combinatorial optimization problem has been widely addressed through metaheuristics. The evaluation function is a key component for the success of metaheuristics; the poor discrimination of the conventional evaluation function of the HP model has motivated the proposal of alternative formulations for this component. This comparative analysis inquires into the effectiveness of seven different evaluation functions for the HP model. The degree of discrimination provided by each of the studied functions, their capability to preserve a rank ordering among potential solutions which is consistent with the original objective of the HP model, as well as their effect on the performance of local search methods are analyzed. The obtained results indicate that studying alternative evaluation schemes for the HP model represents a highly valuable direction which merits more attention.

How the morphology of captive-reared fish is affected by structural enrichment in their rearing tanks is not well *** studies have suggested that deficiencies in rearing environments could produce inappropriate body shape in salmonids(Vehanen and Huusko 2011).garduho-Paz et al.(2010)have found significant differences in body and head shapes of 3-spine stickleback gasterosteus aculeatus,depending on whether fish were reared in an environment with just gravel or in an environment enriched with large stones and artificial plants.

After the microbiology based on Pasteur's method and polymerase chain reaction(PCR), the diagnosis company named Dendris has proposed a third-generation of diagnosis enabling the search of a broad range of pathogens with strong sensitivity and specificity. This extraordinary profile was possible thanks to the use of phosphorus dendrimers for which various techniques of deposition on a given support were investigated and described and analyzed in this report.
