Plants produce nectar in their flowers as a reward for their pollinators and most of our crops depend on insect pollination, but little is known on the physiological control of nectar secretion.Jasmonates are well-known for their effects on senescence, the development and opening of flowers and on plant defences such as extrafloral nectar.Their rol
In this paper, a certain type of ammunition bracket was studied, the stress distribution under working load is calculated by static analysis Ball - Bag - Catcher and display dynamic analysis, the stress distribution result show that the maximum load during the working cycle is the instantaneous impact force.Through ANSYS software, Goodman theory me
This paper presents a particle swarm tracking algorithm with improved inertia weight based on color features.The weighted color histogram is used as the target feature to reduce the contribution of target edge pixels in the target feature, which makes the algorithm insensitive to the target non-rigid deformation, scale variation, and rotation.Meanw
A successful posterior cruciate ligament (PCL) reconstruction depends on multiple factors.Various techniques have been described for PCL reconstruction.Despite the constant evolution of reconstructive techniques, 26% of residual laxity cases Ball - Bag - Catcher with grade I and II positive posterior drawer tests have been reported in the literatur
