1. The paddler then immediately plugs the stern and throws a back loop . 2. These seven steps could be done lineally or in feed-back loops . 3. Invented by Bren Orton, this is a back loop to loop out of the hole. 4. However, due to feed back loops , one may directly or indirectly induce the other. 5. The runners were supposed to do a short out-and-back loop , then three longer laps. 6. It is the same as a 180 orbit except it ends with a front cartwheel end or back loop . 7. A problem arises where an intelligent agents prior expectations interact with the environment to form a self reinforcing feed back loop . 8. Bringing Ian, Thomas and Anton together in an ultimate contest would have required " some major back loops ," 9. Sterols in turn inhibit the cleavage of SREBPs and therefore synthesis of additional sterols is reduced through a negative feed back loop . 10. From the point of the paddler being in a stern squirt the paddler throws bow down into the water to do a bow end or back loop .
