The invention provides sodium channel modulating compounds which are useful for treating diseases or conditions associated with sodium channel activity, such as neuropathic pain. In an exemplary method of the present invention, a first set of data is received by an information handling system. Also disclosed are novel reaction schemes for producing same. Each angled reflective portion 40 includes two inclined surfaces 41, 42, which face the adjacent tubular light sources 17, respectively. The apparatus and method may comprise a vessel having and intermediate wall with a low pressure trap allowing passage of EUV light and maintaining a differential pressure across the low pressure trap. Rim aids gripping of upper barrel and keeps water and soil out of the gap between bottom pot and upper barrel when flower pot is in the nested position.
