In this paper, we study a multicriteria shape design of a highly nonlinear mechanical 2D structure, namely the shape optimization of the aerosol can bottom.In fact, it is made depending on two criteria, the dome growth DG and the dome reversal pressure DRP, that define the resistance of the bottom against the internal pressure.This two criteria are
The blueberry gall midge (BGM) is one of the most important pests of southern highbush blueberries in Florida.Monitoring for BGM using clear sticky traps or bucket traps should begin as early as November.Chemical control should be applied right Chairside Table before bud break and then ten days after bud break, or when at least two BGM are found on

The present work was carried out to study the population dynamics of the mealy plum aphid Hyalopterus pruni (Geoff.) and related parasitoids and predators on apricot trees, during the two successive seasons, 2003 Tapered Candles and 2004, at Qalubia Gover-norate.The obtained data revealed that, the occurrence of H.pruni on apricot trees covered 5 m
