A set of pliers that have a plurality of pins on the forward parts of the plier arms and removable blocks which have apertures that can be placed on selected ones of the pins. Disclosed are methods for the production of epothilone in recombinant hosts transformed with the genes of the invention. The cementious materials need to be capable of being applied by trowel, brush, or spray, forming a strong bond to the surface to which it has been applied. The reference mark may be attached to the scale self-adhesively, or it may be formed by removal of material from the scale, guided by the applicator or template. The remapping is performed automatically as soon as a defective cell is detected. The belt can be wound on the lifting drum by rotation of the latter, in such a way that the windings come to lie on top of one another.
