An exercise wheel is configured to support canines and provide an apparatus that will enable the canine to exercise within a confined space. The exercise wheel is supported on a three bearing stance that can be configured in a freestanding configuration or in a configuration that is mounted to the exterior wall of a dog kennel. In the mounted configuration, the dog will have an unrestricted access to exercise without leaving the confinement provided by the dog kennel. The exercise wheel is freely rotatable from a frame affixed to the kennel wall with a gap between the wheel periphery and the kennel wall being covered by a plastic seal. The circumferential periphery of the exercise wheel is formed of wire mesh to allow waste and debris to pass through.

A perfusion system is so formed that enclosed areas may be formed in the artery system related to the pancreas and the venous system related to the pancreas, respectively, by using balloon catheters, the blood inside the venous system in the enclosed area may be extracted outside the human body, and that, after injecting a pharmaceutical such as anticancer agent into the extracted blood, the extracted blood including pharmaceutical may be returned to the artery system in the enclosed area again.

A method for processing municipal waste substantially reduces the volume of material to be disposed into a landfill by increasing the volume of materials of value collected from the municipal waste and by composting the remaining materials to create a salable product. The process includes the removal of materials of value by magnetic devices to extract ferrous materials, by an air classifier to extract light plastic materials, by an eddy current mechanism to extract aluminum materials, and by a plastic sort mechanism to extract large plastic materials. Composting can be accomplished with a composting vessel that is located in the process either before the materials of value are removed or afterward. A grinding of the materials before a final screening allows the commercial grade compost to be separated from the materials that are to be sent to the landfill for final disposal. An alternative embodiment of the process utilizes a steam pressure vessel to disintegrate the waste material and to destroy any pathogens before materials of value are removed and the small and fine materials are composted. Large materials can be gasified to create heat energy for use in the steam pressure vessel.
