    Abstract: A method and system for reducing the concentration of nitrogen-bound nitrate from at least one of groundwater, surface water, or waste water is disclosed. The system includes an algal photobioreactor system. The photobioreactor includes a transparent tubular structure, a medium disposed inside the transparent tubular structure, and alga configured to adhere to the medium. The photobioreactor further includes a pump, and a light source. The method includes providing contaminant-containing water, adding the water to the algal photobioreactor system, adjusting at least one of temperature, ion concentration, CO2 concentration, pH, light wavelength, ion concentration or light intensity in the algal photobioreactor system to enhance growth of algae, removing water from the algal photobioreactor system, and harvesting the algal biomass. A system and method are also disclosed for reducing the concentration of organophosphates from water via an organophosphate-removing alga.

    Abstract: The present application includes a sheath that is suitable for use in a variety of medical procedures. In one or more implementations, the sheath includes a shunt member, and a curvable portion. The curvable portion may be configured in various orientations to facilitate an intervention, such as a hemodialysis intervention, or the like, by an operator. The curvable portion may be configured to bend between a substantially straight configuration and a curved configuration. In implementations, the sheath may be configured to have detachable and/or interchangeable components (e.g., shunt member, curvable portion, etc.).
