Abstract kicker pro comp 10 By introducing a delayed fractional-order differential equation model, we deal with the dynamics of the stability and Hopf bifurcation of a paddy ecosystem with three main components: rice, weeds, and inorganic fertilizer.In the system, there exists an equilibrium for rice and weeds extinction and an equilibrium for rice
Local resonance is a key reason for fatigue damage of gear housings.Local modals could be excited by vibration caused by gear meshing.Considering the shearer rocker arm for att nighthawk hotspot example,the local resonance characteristics of gear housing are analyzed in this paper.Finite element method is used to obtain the natural characteristics
Abstract Background The relative ease of targeted gene disruption in the social amoeba Dictyostelium has stimulated its widespread use as an experimental organism for cell and developmental biology.However, the field has been hamstrung by the lack of techniques to recombine disrupted genes.Results We describe new techniques for parasexual fusion of
