A variable astigmatic focal beam spot is formed using lasers with an anamorphic beam delivery system. In one embodiment an air flow management system has an air supply providing flow of air proximate an inlet side of the charger housing area and a deflection surface positioned to deflect the flow of air from a first direction to a second direction leading to an impact surface against which the flow of air is disbursed. Each of the end inserts includes an attaching member. Compounds of the present invention find utility in the treatment of mammalian cancers and especially human cancers including but not limited to malignant melanoma, colorectal cancer, ovarian cancer, papillary thyroid carcinoma, non small cell lung cancer, and mesothelioma. According to the invention, the embossing patterns include at least two adjacent zones whose projections have, respectively, a different density andor a different surface area at the peak so as to produce a relief effect on the product. The confinement portion is used to confine the control lever of the sprinkler nozzles.
