A flame-holding nozzle for a combustion turbine engine is disclosed. The method can further include enabling, by way of equipment of the provider, equipment of the at least one customer to communicate with equipment of the vendor, and receiving at the equipment of the provider transactional information indicating that the at least one customer initiated an order for a product or service from the vendor for a transactional amount. The projection objective can also include a polarization correction element which has at least two subelements of birefringent, optically uniaxial material and having at least one respective aspheric surface. The air-bag has an inflatable region towards the upper part of the air-bag and an inflatable region towards the lower part of the air-bag. Defects in the glassification surface will absorb most of the Cu2 ions, concentrations of Cu2 ions will therefore from around these defects.
