Compliance with environmental protection regulations, in particular, community noise requirements, constitutes one of the major obstacles for designing future supersonic civil aircraft.Although there are several noise sources that contribute to the total noise level of supersonic aircraft, it is the turbulent jet that appears most problematic; jet
Accurate prediction of loads on mechanical couplings is crucial in assessment of loads on coupled structures and in optimization of mechanical coupling design.In this paper, a contact element model Flange Nut is introduced to represent prismatic joints.A twofold pushing convoy in shallow water was taken for time domain numerical simulations in regu
Climate change has exacerbated the impact of abiotic stresses, mainly drought, on plant production.Plant selection, breeding, and genetic engineering to increase drought tolerance are costly and time-consuming.To mitigate drought stress, plants employ adaptive mechanisms and interact with beneficial microorganisms, Dill Weed such as plant growth-pr
Reconstruction of large defects of the anterior abdominal wall in patients operated for cancer diseases is mainly performed in the presence of Pants concomitant ventral hernia or by direct ingrowth of the tumor in the tissue of the anterior abdominal wall.Currently in the treatment of this category of patients, the method of choice is the use of al
