The invention relates in part to a folded dipole having a dipole axis and a pair of arms which together have a profile which is concave on one side and convex on the other when viewed along the dipole axis. The method can include providing an incentive to a user operating a device in an ad hoc network and determining network resources associated with providing the incentive. After receiving one or more commands from the network node, to perform random access procedure, the user equipment performs one or more attempts to initiate random access procedure by sending one or more access request messages to the network node as a response to the received command. The distal end is configured to engage the target such that, upon activation of the probe, the target is treated. Using blasting to form the nodules produces an inferior coating in contrast to the electroless nickel boron coatings having a columnar structure. One form of phospholipid-docosahexanoic acid is phosphatidylcholine-docosahexanoic acid, and another form of phospholipid-docosahexanoic acid is phosphatidylethanolamine-docosahexanoic acid.
