Abstract: An example water purification system for purifying high concentration feed solutions includes a high rejection forward osmosis module, one or more low rejection modules, and a high rejection reverse osmosis module. The low rejection modules may have different rejection levels. The system may be pressurized by one or more pumps. One or more of the low rejection modules may include one or more nanofiltration (NF) membranes. The draw solution may comprise a monovalent salt, a multivalent salt, or a combination of both.

Abstract: The present disclosure describes methods and systems for separating a fluid. The methods and systems include a plurality of osmosis modules operably coupled together. At least some of the plurality of osmosis modules include an osmosis membrane, a feed side on a first side of the osmosis membrane; a draw side on a second side of the osmosis membrane; a feed inlet operably coupled to the feed side; a draw inlet operably coupled to the draw side; a feed outlet operably coupled to the feed side; a draw outlet operably coupled to the draw side. The at least some of the plurality of osmosis units further including a feed recirculation loop operably coupled to the feed inlet, the feed outlet, and a feed inlet of a downstream osmosis module; and a draw recirculation loop operably coupled to the draw inlet, the draw outlet, and a draw inlet of a downstream osmosis module.

Abstract: Methods and devices for identifying agents that block binding or activation of peripheral membrane proteins are disclosed.

Abstract: A pool heating system has a housing, a water inlet, a plurality of pipes comprising baffles, and a water outlet. The baffles create turbulence in the flow of the water, increasing kinetic energy and pressure (compression). As a result of the compression and kinetic energy, the temperature of the water increases. The water then passes to the outlet, where it exits at a higher temperature than when it entered.

Abstract: Described herein are methods useful for screening candidate biochemical entities targeting a target biochemical entity and methods useful for identifying a binding moiety for a target biochemical entity. The invention provides methods of screening drug candidates targeting a target biomolecule, comprising selecting a drug candidate based on a signal difference between a first signal and a second signal. The signal difference indicates a difference in an in vivo or in vitro pharmacological property. The first signal is produced upon binding between the target biomolecule and a first candidate by contacting the target biomolecule with the first candidate, and the second signal is produced upon binding between the target biomolecule and a second candidate by contacting the target biomolecule with the second candidate.
