Abstract: A decontamination method for subsurface aquifers having per- and polyfluoroalkyl substances (PFAS) contaminants by injecting gas through a screened well or open tube through a porous media to form buoyant material where the PFAS contaminants accumulate on and/or in the buoyant material and rise to the water table or top of the aquifer with PFAS that desorbs from the buoyant material and concentrates in the shallow groundwater, and extracting or sequestering the groundwater near the water table or top of the confined aquifer and/or collecting the buoyant material for treatment. The method may include treatment of aquifer material consisting of gravel, sand, silt, clay, or fractured geologic media, or combination, and extraction through phytoremediation, groundwater extraction wells, wellpoint systems, or groundwater extraction trenches and include a seal and/or check valve near the water table in the trench to selectively permit water and buoyant material to flow upward.

Abstract: The invention provides methods of treatment that prevent the onset of Mesial temporal lobe epilepsy (TLE) in a subject, or which reduce the severity of TLE in a subject, by administering a NKCC1 inhibitor to the subject after the subject has suffered from an insult known to precipitate TLE.

Abstract: A method is provided for reducing the concentration of radioactive materials or other trace contaminants in fluids withdrawn from subterranean reservoirs and also fluids in reservoirs. The method involves deposition of sorbent solids including, but not limited to, fine ion exchange resins, within the reservoir matrix surrounding a production well to act as an in-situ filter for dissolved radionuclides or other contaminants present in reservoir pore waters. For this purpose, the sorbent solid is either a) precipitated within the reservoir matrix by the reaction of ions or molecules of two or more carrier solutions or b) directly introduced into the reservoir as a solid component of a solid-liquid slurry using high-pressure injection techniques.

For this purpose, the sorbent solid is either a) precipitated within the reservoir matrix by the reaction of two or more carrier solutions or b) directly introduced into the reservoir as a solid component of a solid-liquid slurry using high-pressure injection techniques. Thereafter, fluids produced by the well contain significantly lower concentrations of radionuclides (e.g., principally radium and uranium ions), as radionuclides are removed from the inflowing reservoir fluids by means of ion exchange, adsorption, chelation, chemisorption, or coprecipitation with the in-situ filter medium.

Abstract: A drive mechanism for a boat having the motor located inboard. The mechanism disclosed includes a gearbox located outboard of the transom with an input shaft extending toward the inboard motor and an output shaft extending aft toward a propeller shaft. A univerasl joint coupling is provided to drive the propeller shaft while a gimbal ring is employed to universally mount a propeller shaft housing such that the propeller may be used for steerage as well as forward thrust. The gearbox is disclosed as including a first gear pair capable of being changed to provide different output ratios. A second drive link in the gearbox gives a selection of directions of rotation of the propeller shaft. In a first instance, a gear pair is employed. In a second instance, a chain drive is employed. Access is provided into the gearbox by a plate located between the gearbox and the transom. This plate provides a mounting for the drive links within the gearbox.
