Le béton demande beaucoup de temps avant de durcir complètement, vous pourriez voir apparaître des fissures capillaires. Ces fissures ne permettent pas l’infiltration d’eau. Si votre fissure n’est pas plus large que l’épaisseur de trois cartes de crédit (3mm), vous n’avez pas à vous inquiéter. Par contre, il faudra cependant vous occuper des fissures plus grossières en les corrigeant vous-même ou en les faisant corriger par un entrepreneur spécialisé.
"Homes are selling faster and faster in the Montréal area, as the average selling time, for all property categories combined, was 80 days in November, which is seven days less than one year ago," said Nathalie Bégin, President of the GMREB board of directors. "Single-family homes and plexes sold the fastest – in an average of 72 days – while it took an average of 94 days for a condominium to sell," she added. 
There is a size correlation which determines whether males become patrollers or hoverers. Patrollers tend to be larger so that they can better protect and copulate with emerging females. Smaller males are usually unable to compete as well, and so have to make the best out of a bad situation; thus, they become hoverers. Each group has a different set of behaviors. The patrollers move over a large space containing many other patrollers. Usually, patrollers will frequent the same spots over the course of their lives. Since the area is so large, the cost to defend it against other patrollers would be much greater than the potential mating benefits, so the patrollers show very little territoriality.[11] Patroller males will usually only fight when a breeding female is near. In contrast, each hoverer stakes out an area of about one meter in diameter. These areas don’t overlap with other hoverers. Any fast moving object (i.e. bee, dragonfly, leaf, etc.) that enters a territory will be quickly chased. The chase allows the male bee to determine if a female is unmated, or if an enemy male is in his territory. If it is a male bee, the territory owner will chase it out, but not beyond the boundary of the territory. What is interesting is that every day (or even every several hours) the territory holder will abandon the area to establish a new zone. Often the male will never return to the vacated area, and it will be taken over by another male. This shows that hoverers show a low site tendency but strong territoriality.[11] A balanced ratio of patrollers to hoverers is maintained, and thus, this ratio is an evolutionary stable strategy. If more males become patrollers, then the hoverers will benefit from the reduced competition, and the hoverers' genes will spread until the stable ratio is returned to. The same thing will happen if more males become hoverers.
Centris pallida is a species of solitary bee native to North America. It lacks an accepted common name; however, it has been called the digger bee, the desert bee, and the pallid bee due to its actions, habitat, and color respectively. The solitary nature of this bee allows for a dual-strategy mating system which produces an evolutionarily stable state resistant to invading strategies. These bees have also evolved to withstand the high temperatures of their native habitat. C. pallida routinely has internal temperatures within 3 degrees Celsius of death.

A broker provides a complete and accurate description of the property, performs a comparative market analysis, proposes a marketing strategy, verifies the specifications of the desired property, prepares and submits the promise to purchase to the seller, negotiates in the best interest of his or her client, and ensures that all conditions are met on time for the signing of the notarial act.
