The present invention discloses a parabolic dish-shaped electromagnetic wave front concentrator composed of a plurality of petal like identical interchangeable segments. The liquid concentrate includes a complex resulting from an in-situ reaction of a cation source, an oxidant, a halide source having at least one iodine atom, and a non-mineral acid, or a mixture of a non-mineral acid to about 50% of a hydrophilic solvent by volume. Simulation, permutation shuffling, and permutation sliding each use the comparison of the experimentally found occurrence of association between the two health events to the null distribution of the association statistics, obtained by independently simulating the two health events. A data processing apparatus for processing and presenting the data is also provided. An inlet coupling formed of a non-metallic material and having an inlet opening extending therethrough is molded about receiving end such that receiving end is sealingly received within inlet opening.
