This invention provides an apparatus and method for injecting gas within a plasma reactor and tailoring the distribution of an active species generated by the remote plasma source over the substrate or wafer. The method comprises the step of injecting into the fat pad of the host a biocompatiable solution having physico-chemical and mechanical properties substantially similar to a fatty acid mixture normally present in a healthy fat pad. Thereby, a transmission of erroneous text commands to the network application server can be prevented so as to reduce total processing time and response delays. The standing post has two first engagements at two sides of its arc shape post body or on the wall of the socket. The moldings may be used as catalysts or catalyst supports for the preparation of vinyl acetate monomer, the hydration of ethylene and the hydration of propylene.
