The oolution light up response of N2O emissions to nitrogen (N) addition is usually positive, but its response to phosphorus (P) addition varies, and the underlying mechanisms for the changes in N2O emissions remain unclear.We conducted field studies to examine the response of N2O emissions to N and P addition over two years in three typical alpine
Throughout history, for the new to emerge, there must be a challenge to the old order of a world that seeks to be abolished.It is the law of continuity which, paradoxically, is meant to function periodically through rupture.The obsession with breaking the present from the similarities of the past generates new spiritual identities, manifested also
The optimal wheel/rail adhesion of heavy-duty locomotives under traction must be determined given that suboptimal wheel/rail adhesion may corky lala result in low creep utilization, skidding, and idling.Here, we present an algorithm for the online identification of adhesion parameters.The algorithm is used for the online parameter estimation of the
In order to improve working accuracy of motor unit of mine cable winding car, aiming at problems of load disturbance and speed adjustment in the operation control of cable motor and reel motor, a cross-coupling control method for motor of mine cable winding car was proposed.Fruit fly optimization algorithm (FOA) is used to optimize PI parameters of
