Abstract: Membranes and filtration modules for producing a concentrated feed stream and a diluted feed stream during operation in a water purification or wastewater treatment system. Filtration modules are provided that include a semipermeable membrane having a first side and a second side, the first side configured to receive a first feed solution stream from a first feed solution source and the second side configured to receive a second feed solution stream from a second feed solution source. The semipermeable membrane may be configured to operate at a hydrostatic pressure on the second side of the membrane from about 1% to about 40% of the hydrostatic pressure on the first side of the membrane, and may in some cases exhibit a salt rejection of from about 60 percent to about 90 percent during operation.

Abstract: An example system includes a vehicle having a prime mover motively coupled to a drive line; a motor/generator selectively coupled to the drive line, and configured to selectively modulate power transfer between an electrical load and the drive line; a battery pack; a DC/DC converter electrically interposed between the motor/generator and the electrical load, and between the battery pack and the electrical load, the DC/DC converter comprising a DC/DC converter housing; and a covering tray positioned over a plurality of batteries of the battery pack, the covering tray comprising a connectivity layer configured to provide electrical connectivity to terminals of the plurality of batteries.

Abstract: A system includes a PTO device that selectively couples to a driveline of a vehicle, a motor/generator electrically coupled to an electrical power storage system, and a shared load selectively powered by one of the driveline or the motor/generator. The PTO device further includes a coupling actuator that couples the shared load to the motor/generator at a first selected ratio in a first position, and couples the shared load to the driveline at a second selected ratio in a second position.

Abstract: Technology for tracking changes to a database and providing the changes to a subscribing computing device. In an illustrative implementation, a method may involve subscribing a computing device to changes of a portion of a multi-tenant database and accessing a plurality of change events stored in a log of the multi-tenant database in parallel. The method may further involve storing the plurality of change events in a persistent data store separate from the multi-tenant database and processing the plurality of change events to create an ordered set of change events. The ordered set of change events may then be provided to the computing device that subscribed to the changes.

Abstract: Disclosed herein are organic-inorganic hybrid materials, in particular polyionic nanoclays, along with methods of making and using the same. The functionalized organic-inorganic hybrid materials are preferably of a phyllosilicate structure and comprise an octahedral ionic layer sandwiched between two tetrahedral layers, one or more charged chemical moieties covalently bonded to the tetrahedral layers, and optionally one or more counterions or functional groups associated with the hybrid materials. Methods of producing the same, by contacting a silane with a nucleophile and hydrolyzing the product thereof in the presence of a metal salt, are also provided.

Abstract: Techniques for database multiplexing. Within a group of two or more logical databases, each having a plurality of database nodes, the group of logical databases being part of a multitenant database environment that stores data for multiple client entities each identified by a tenant identifier (ID) having one of one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities, the tenant ID is used to determine a mapping between the tenant ID and one of the plurality of logical databases.

Abstract: A dental device to be placed in the oral cavity between the lower teeth and the tongue for use as a combined saliva/fluids ejector and tongue deflector/retractor in dental treatments, comprising: a substantially flat head portion with hollow tubing on a portion of its periphery, and suction holes (preferably oval-shaped and protected from soft tissue entrapment by raised ribs) and in communication with the hollow tubing; a body portion provided with a bore and a ratchet mechanism, the bore in communication at its upper end with the hollow tubing and at its lower end with a suction system; and an arm having a collar adapted to adjustably engage with and disengage from the teeth of the ratchet mechanism. The cross sections of the collar and ratchet mechanism portion of the body are essentially square in shape.
