Abstract: In healthy subjects, especially the ones with increased risk for developing cancer due to genetic predisposition or other risk factors, cancer can be prevented by immunization with a cancer vaccine. Oncoantigens present in the vaccine preferably are incubated with IFN-?, IL-2 or both. To prevent cancer recurrence, cancer patients in remission are given a prolonged course of immunizations with a vaccine that includes, for example, oncoantigens in combination with immune competent cells (e.g., bone marrow and T lymphocytes). The bone marrow and T lymphocytes are optionally treated with IFN-?, IL-2 or both.

Abstract: A method for modifying a target includes directing exhaust from multiple engines, preferably jet engines, towards the target. The target being modified can be, for example, a fire, an atmospheric system, a storm, snow, a gathering, a spill, an emission, a discharge, a mud slide, or a dust. The operation and/or deployment of the engines can be by remote control or robotics. In one example, a system for modifying a target includes a support for securing multiple jet engines and a fuel source. Preferably, the jet engines are mounted on turrets that are capable of being rotated.
