Is the dopamine sensitive adenylate cyclase in the rat substantia nigra coupled with 'autoreceptors'?
A drilling vessel has a hold adapted to store and transport drilling pipes arranged parallel to the length of the vessel. An elevator extends lengthwise of the vessel in the mid-plane of the hold and communicates between a plurality of superposed holds and the deck. An elongated overhead crane that extends longitudinally of the vessel is arranged in the or each hold, the crane being supported at its ends on tracks extending transversely of the hold located fore and aft of the hold. These tracks are interrupted at their middle for vertical passage of the ends of the elevator. The ends of the elevator, in turn, ride on vertical tracks that are interrupted for passage of the ends of the cranes. In this way, the elevator can move vertically and the cranes traverse horizontally, without interfering with each other.
A study of the factors which affect the fold kinematic activities has been presented,through the design analysis,the sensitivity of acceleration vs.design was obtained.According to the sensitivity,the lengths of linkage and crank were determined as design variables.The optimization technique was applied to an ADAMS Model so as to minimize the value of acceleration.The result showed that the value of jerk was also improved while the value of acceleration was optimizing.It will improve the vibration properties and be the foundation of dynamics simulation later on.
