Methods, systems and an apparatus for multi-component mixing and spray application, including a portable, balanced frame having uniformly distributed weight over the wheels, and insulated chemical container holders for receiving replaceable materials containers therein. , the product of 55 Gauss \u03bcm or more of a remnant magnetic flux density and a film thickness, and includes at least a transition metal-rich rare earth-transition metal amorphous alloy layer and a rare earth-rich rare earth-transition metal amorphous layer. The vias are connected to traces on the circuit board by way of an exit structure that includes two flag portions and associated angled portions that connect the flag portions to circuit board traces. The buffer is configured to store the data from the region of the local memory of the other processing unit. The compounds according to this invention possess anti-cell proliferation activity and show an increased plasma-stability.
