Synthesis of Diamond Thin Films on TC4 by Using a Scanning Linear Flame

A scanning linear flame is used to deposit diamond films over a large area, and with high quality and good continuity by employing appropriate cooling means for the substrate. It is found that the structure and morphology of the deposited films mainly depend on the substrate temperature, the ratio of 0₂ to C₂H₂ flow rate and the relative position of the substrate with respect to the flame. These factors affecting the structure and morphology of diamond films are interrelated. Moreover, the influences of surface pretreatments on nucleation and growth of diamond films are also studied. The experimental results show that the nucleation density of diamond films is enhanced by scratching the surface of the substrate with diamond grit and initially coating a mechanical pump oil layer. For the substrate surface etched with metallographic etching acid, the nucleation and growth of diamond films are very uniform. In addition, the adhesion between the film and substrate is enhanced. Nucleation is favored on the prominent features of the substrate, i.e. scratch and crystal boundary.

Cloning and characterization of a symbiosis-related gene from an ectomycorrhizal fungus Laccaria bicolor

Point-to-point functional movements involve simultaneous shoulder and elbow joint rotations. In able-bodied subjects these movements are fully automatic, and feed-forward control ensures the synergistic activity of many muscles. Synergy between joint rotations was defined and described as a scaling between joint angular velocities [19]. Similarly, subjects who can control their shoulder movements may be assisted in reaching tasks by functional electrical stimulation (FES) of elbow extensor muscles. The synergistic control paradigm can be implemented in real-time by employing a hierarchically structured production-rules method. The use of production-rules necessitates the acquisition of knowledge and the assembly of a rule-base. A nonparametric technique was designed for the identification of the rules. The identification process was divided into two phases: determination of the scaling parameters, and determination of the stimulation parameters. The scaling parameters, needed for the coordination of movements, were determined in able-bodied subjects. Those depend exclusively on the initial and target positions of the hand. The number of scalings could be reduced by dividing the workspace into 12 zones. The stimulation parameters, needed for the execution of movements, were determined in subjects with paralyzed elbow extensor muscles by identifying triplets: elbow angular velocity, elbow angular acceleration (velocity increments), and the corresponding pulse durations for various classes of movements and loads attached to the hand.
