The invention includes deposition apparatuses having reflectors with rugged reflective surfaces configured to disperse light reflected therefrom, andor having dispersers between lamps and a substrate. In preferred embodiments a rim extends outwardly from a first surface of the panel by a distance of less than \xbd inch, and preferably by only \u215b inch or even 116 inch. The small region eliminating circuit compares a small region with four detection patterns, discriminates it as a region other than the feature -region if no match is found and causes a center pixel of a window of 33 pixels to have a logical value of zero. The methods and kits of the present invention satisfy the need to classify patients at genetic risk for drugalcohol seeking behavior prior to or upon entry to residential and or non-residential chemical dependency and pain programs.
