Abstract: The effervescent tablet for enhanced oil recovery is made of multi-walled carbon nanotubes (MWCNTs), sodium dodecyl sulfate (SDS), sodium phosphate monobasic (NaH2PO4), and sodium carbonate (Na2CO3). To perform enhanced oil recovery, a suspension is first prepared by adding the effervescent tablet to water. This preparation may be performed at room temperature. Steam is then injected into the oil well, followed by flooding the oil well with the suspension. One-third of the pore volume of an oil reservoir of the oil well may be injected with the steam, and two-thirds of the pore volume of the oil reservoir may be flooded with the suspension.

Abstract: A sample observation container and methods of use thereof are provided. The sample observation container includes a base and one or more sidewalls extending from the base. The one or more sidewalls form a sample enclosure for holding a sample undergoing a sample observation test such as sedimentation photographical capturing and dynamic light scattering, among other tests. The one or more sidewalls form a sample enclosure of adjustable cross-sectional area. The cross-sectional area may be adjusted by feeding or retracting a flexible sheet from a source roll to the sample enclosure. The cross-sectional area may further be adjusted by removing an innermost sidewall from among one or more nested sidewalls. The containers allow for physical adjustment of the cross-sectional area while performing subsequent sample observation tests, thereby allowing assessment of the effects of container size on the results of the sample, such as particles in liquid suspension.

Abstract: The convertible stairs for wheelchair accessibility combine a tiltable staircase with a vertically movable platform. The tiltable staircase includes rotating stairs which can be angularly adjusted between a stepped configuration and a planar, ramp-like configuration. Proximal ends of first and second staircase frames are pivotally secured to the platform such that selective raising and lowering of the platform causes the tiltable staircase to tilt up and down. When the stairs of the staircase are rotated into the planar, ramp-like configuration, the platform may be fully raised to tilt the staircase upward, creating a horizontal surface for the wheelchair to cross from the platform to an upper floor or level. To exit the upper floor or level, the wheelchair user reverses the process, returning to the platform which is lowered to the lower floor or level, also lowering the staircase. The stairs may then be rotated back to a stepped configuration.

Abstract: The confined plunging liquid jet reactor with energy recovery includes a downcomer having an upper end, an open lower end, and a gas inlet for receiving gas, the downcomer extending into a liquid reservoir in a tank. A nozzle is mounted on the upper end of the downcomer for receiving a pressurized liquid to generate a liquid jet. The liquid jet impinges on liquid contained within the downcomer, creating turbulence and bubbles to entrain gas introduced through the gas inlet into the liquid reservoir as the jet travels downward in the downcomer. A riser is disposed around the downcomer and defines an annular air lift column. Unentrained gas and liquid exiting the downcomer rises in the air lift column with significant energy, the upper end of the riser being connected to a turbine coupled to a generator to recover energy from the air lift column.

Abstract: The secure baggage claim system uses radio frequency identification (RFID) tags or the like to associate a particular item of baggage with the owner of that item of baggage. The secure baggage claim system includes a housing having a baggage entry opening, a baggage retrieval opening, and a vertically arranged carousel disposed within the housing for carrying and rotating a plurality of baggage carrying trays. A primary RFID tag reader reads a primary RFID tag secured to the item of baggage to associate the item of baggage with identification information corresponding to an individual. The item of baggage is further associated with one of the baggage carrying trays selected to carry the item of baggage. A door releasably covers and seals the baggage retrieval opening and is releasably locked by a locking mechanism. Authenticating input associated with the individual unlocks the door for retrieval of the item of baggage.

Abstract: The apparatus for testing the stability of dispersed particles in flowing suspensions includes a sample receiving cup having a lower wall and an open upper end. A cup outlet is disposed in the lower wall, and the sample receiving cup is adapted for receiving a suspension sample through the open upper end. A pump is in fluid communication with the sample receiving cup through the cup outlet. The pump extracts the suspension sample through the cup outlet to produce a pressurized suspension stream. A recirculation pipe has a pipe inlet and a pipe outlet, the pipe inlet being in fluid communication with the pump for receiving the pressurized suspension stream, and the pipe outlet returns the pressurized suspension stream to the sample receiving cup, through the open upper end thereof. A power monitor is in communication with the pump for monitoring the power output of the pump.

Abstract: The anti-inflammatory composition may be administered to a subject in need thereof to prevent or reduce inflammation, including inflammation resulting from asthma. The anti-inflammatory composition may comprise both onion bulb extract and one or more glucocorticosteroids, particularly a low-dose glucocorticosteroid. The anti-inflammatory composition may be administered to a subject at risk of developing asthma to prevent the progression of asthma. The anti-inflammatory composition may act by reducing pEGFR levels, or by inhibiting other inflammatory pathways.
