A spinal fusion implant of non-bone construction to be introduced into any variety of spinal target sites. The spinal fusion implant of the present invention includes a top surface, a bottom surface, first and second lateral sides, a proximal (posterior) end and a distal (anterior) end. The spinal fusion implant of the present invention may be used to provide temporary or permanent fixation within an orthopedic target site. To do so, the spinal fusion implant may be introduced into a disc space while locked to a surgical insertion instrument and thereafter employed in the proper orientation and released. Once deposited in the disc space, the spinal fusion implant of the present invention effects spinal fusion over time as the natural healing process integrates and binds the implant.

An apparatus and method delivers an expandable body member into a uterine cavity of a uterus through a cervical opening and deploys the expandable body member in the uterine cavity. The expandable body member in a compressed state is inserted into the uterine cavity. A fluid is provided to the uterine cavity at a pressure sufficient to inflate the uterine cavity. The expandable body member expands from the compressed state to the expanded state. After expansion of the expandable body member and inflation of the uterine cavity, the fluid pressure is relieved thereby collapsing the uterine cavity about the expandable body member in the expanded state such that an endometrial layer of the uterus and a surface of the expandable body member substantially contact each other in a facially opposing relationship maximizing contact therebetween. The apparatus which performs the method includes an elongated tubular member having the expandable body member connected to a distal portion of the elongated tubular member and a fluid-providing device connected to a proximal portion of the elongated tubular member.

Methods for accurately assessing the condition of a petroleum reservoir and designing and implementing a plan of action to increase production and recovery of petroleum from the reservoir. Information is gathered using a unique set of metrics and information gathering techniques and analyzed in a targeted fashion by properly weighting the data in the context of the particular reservoir and goals of the producer. A reservoir rating is generated using asymmetric analysis of metrics and then used to formulate a plan of action. Production architecture (e.g., number, location and manner of constructing oil and injector wells) is then constructed according to the plan of action. Reservoir performance can be continuously monitored and used to verify production and recovery goals and / or provide triggers or alarms to alter production equipment.

The invention relates to pharmaceutical formulations, and more particularly to formulations containing cannabinoids for administration via a pump action spray. In particular, the invention relates to pharmaceutical formulations, for use in administration of lipophilic medicaments via mucosal surfaces, comprising: at least one lipophilic medicament, a solvent and a co-solvent, wherein the total amount of solvent and co-solvent present in the formulation is greater than 55% wt / wt of the formulation and the formulation is absent of a self emulsifying agent and / or a fluorinated propellant.

The invention teaches a practical method of recovering CO2 from a mixture of gases, and sequestering the captured CO2 from the atmosphere for geologic time as calcium carbonate and provides a CO2 scrubber for carbon capture and sequestration. CO2 from the production of calcium oxide is geologically sequestered. A calcium hydroxide solution is produced from the environmentally responsibly-produced calcium oxide. The CO2 scrubber incorporates an aqueous froth to maximize liquid-to-gas surface area and time-of-contact between gaseous CO2 and the calcium hydroxide solution. The CO2 scrubber decreases the temperature of the liquid and the mixed gases, increases ambient pressure on the bubbles and vapor pressure inside the bubbles, diffuses the gas through intercellular walls from relative smaller bubbles with relative high vapor pressure into relative larger bubbles with relative low vapor pressure, and decreases the mean-free-paths of the CO2 molecules inside the bubbles, in order to increase solubility of CO2 and the rate of dissolution of gaseous CO2 from a mixture of gases into the calcium hydroxide solution.The CO2 scrubber recovers gaseous CO2 directly from the atmosphere, from post-combustion flue gas, or from industrial processes that release CO2 as a result of process. CO2 reacts with calcium ions and hydroxide ions in solution forming insoluble calcium carbonate precipitates. The calcium carbonate precipitates are separated from solution, and sold to recover at least a portion of the cost of CCS.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

A potted plant watering system that uses the capillary action of a wick to draw water up from a water reservoir and into the soil of a potted plant via a plurality of fingers of a wick support member that secure the wick in predetermined patterns and maximizes soil contact during wet and dry conditions and distributes water evenly throughout the plant pot. A water flow control device attaches to the wick support member and by separating the wick's strands from contact with the water, controls the flow of water through the wick. A float mechanism provides for a reservoir level indication with minimum rise and arc of the float rod above the surface of the water reservoir and therefore minimizes risk of rod damage and observer confusion. The wick, flow control, and water level indication systems can be used with any existing plant pot equipped with a drainage hole.
