And Control

In this paper a CNC machining station (Computerized Numerical Control) is developed for its later integration into a manufacturing cell prototype, considered as a mechatronic system. For this, it is assumed the task of carrying out the mechanical and control design of a CNC vertical machining center, with the sole objective of machining parts with specific characteristics from material removal method. The development and design of a CNC machining station began with the manufacture of mechanical structure from rigid and suitable materials for its feasible construction; 3D printing of parts was necessary for fastening stepper motors used and its respective control was achieved by using Arduino software and hardware platform and Universal Gcode Sender, in conjunction with a stepper motor control module. Subsequently, necessary adjustments and programming are made to carry out corresponding functional tests and to ensure adequate machining of required parts, which marks continuity of integration process of this station to a manufacturing cell prototype.

And Control

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

And Control

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.
