Abstract: The disclosure provides a way to supplement the tidal volume delivered to the patient by a leaking re-breather when the delivered volume becomes less than that set by the ventilator (in either pressure-regulated or volume modes). This may be accomplished with a shunt—a gas conduit joining the non-patient side of the re-breather to the patient side. A low-resistance, plenum or a draw-over vaporizer may also be incorporated into the gas pathway. Such a device may include a housing with a movable partition separating an actuating side from a patient side. The housing includes a ventilator orifice for pneumatic communication between a ventilator and the actuating side and a patient orifice for pneumatic communication between the patient side and a patient. A shunt defines a bypass flow path from the actuating side and to the patient side when the moveable partition is at a maximal displacement towards the patient side.
Abstract: The present invention includes a method for thermodynamic modeling of asphaltene precipitation comprising: calculating the Gibbs free energy for the transition between asphaltene molecules in solution into an imaginary crystalline asphaltene nanoaggregates or asphaltene nanocrystals; calculating the Gibbs free energy for the transition between asphaltene nanoaggregates or nanocrystals redissolving into colloidal asphaltene nanoaggregates using the computer: and predicting asphaltene solubility in a solvent, wherein the predicted asphaltene solubility is used to add a solvent to a liquid, semi-solid, or solid comprising asphaltenes to prevent, e.g., fouling of a wellbore, pipeline, downstream unit operations, to provide flow assurance for crude oil pipeline network, or for petroleum crude blending.

Abstract: Methods for optimization of liquid oil production by huff-n-puff in shale reservoirs to achieve an improved (and optimal) oil recovery factor. The process determines and utilizes the optimum huff and puff times, number of cycles and soaking time under practical operation and reservoir conditions. The huff time in the process is a period so long that the pressure near the wellbore reaches the set maximum injection pressure during the huff period. The puff time in the process is the time required for the pressure near the wellbore to reach the set minimum production pressure during the puff period. Soaking is typically not necessary during the huff-n-puff gas injection in shale oil reservoirs. The number of huff-n-puff cycles is determinable by the time in which the economic rate cut-off is reached.

The device can be used at front line, hospitals, clinical laboratories, airports, groceries, homes, and the like. The device can be used as a single probe for single use or home use, or the device integrated into a carrousel or multiple probe magazine for fast detection of multiple samples simultaneously.
