Abstract: A system, apparatus and method of enhancing the growth of crops using gaseous media with deprived Oxygen content. A plant growth apparatus is disclosed including a source of Nitrogen gas (N2); a source of Carbon Dioxide gas (CO2 gas); a compressor connected to the source of Nitrogen gas and to the source of CO2 gas; and one or more gas emitters connected to the compressor and adapted to be disposed near plants in a greenhouse or other enclosure. During use, the gas emitters emit a predetermined amount of Nitrogen gas and a predetermined amount of CO2 gas, in a mixture, to the plants, whereby a diffusion gradient is created in each plant moving Oxygen gas (O2) out of the plant and enhancing photosynthesis in the plant.

Abstract: Methods and systems are described for creating chronic vascular access or hemodialysis. These methods and systems eliminate the insertion of needles which are now required for using the available methods of obtaining vascular access. Thus multiple complications due to needle insertion through skin, tissue, and vein or graft wall are prevented. A low-profile stable transcutaneous implant's external surface and stability minimizes infection. The implant is readily joined to a connector device that functions substantially automatically and which provides high blood flow volumes for hemodialysis.

Abstract: A method and system are provided for performing dialysis. The system provides needleless vascular access which reduces the repeated traumas of conventional dialysis by providing a vascular graft and port combination which interfaces with a specially-designed catheter system. The installed implant is low profile, small and stable, and saddles the vessel to secure the protruding surface tissue above. The stability of the port is maintained by features that encompass the vessel and the surrounding tissue. These features are enhanced by the catheter attachment, which also provides reduced trauma and provides convenient access to the implant for performance of dialysis functions.
