A wind energy systems includes a shroud for each turbine. In some embodiments, tuned shielding can be achieved by utilizing different structures andor arrangements of shielding-wirebonds to increase shielding in areas where needed, and to decrease shielding where not needed. A positioning device controls a position of the microdeposition head relative to the substrate. Attraction detaching pieces are built in rows of synthetic resin link modules to detach and release the articles. According to the invention, the load carrying capacity of the individual wing couplings and their direction of force take-up are matched to each other such that in the case of a defect in one of the couplings the maximum load carrying capacity of the remaining couplings is adequate for safe normal flight operation. Long term administration of the cross-linked polyamine salts of the invention increases HDL levels and decreases LDL levels in patients.
