Abstract: Capture of hydrogen sulfide from a gas mixture may be accomplished using an aqueous solution comprising an amine. Certain sterically hindered amines may selectively form a reaction product with hydrogen sulfide under kinetically controlled contacting conditions and afford a light phase and a heavy phase above a critical solution temperature, wherein the hydrogen sulfide may be present in either phase. Upon separation of the light phase from the heavy phase, processing of one of the phases may take place to remove hydrogen sulfide therefrom. Recycling of the amine to an absorber tower may then take place to promote capture of additional hydrogen sulfide.

Abstract: Solids dissolution may be promoted using a solvent blend comprising a disulfide solvent, particularly additional solids present in combination with elemental sulfur deposits. The solvent blends may comprise at least one disulfide solvent, at least one amine solvent, at least one ketone solvent, at least one ester solvent, and optionally water. Solids dissolution methods may comprise: identifying one or more solids in addition to elemental sulfur to be contacted by the solvent blend; adjusting a composition of the solvent blend to afford selectivity for dissolution of at least a portion of the one or more solids; and contacting the solvent blend with elemental sulfur and the one or more solids to promote at least partial dissolution thereof.

Abstract: A distributed adaptive coding and modulation network includes multiple network hubs that move relative to Earth, communicate among each other using intra-hub links, communicate with endpoint devices via wireless links, and elect one network hub to operate as a leader hub. A remainder of the network hubs operate as follower hubs. The leader hub is operational to negotiate a current modulation and coding scheme with the follower hubs based on a session management protocol, communicate with a first endpoint device, relay data between the endpoint devices using the current modulation and coding scheme, and dynamically renegotiate the current modulation and coding scheme in response to a change in link conditions based on the session management protocol. An edge follower hub is operational to communicate with a second endpoint device, and relay the data between the endpoint devices through the inter-hub links using the current modulation and coding scheme.

Abstract: Methods for utilizing and regenerating solvent mixtures for dissolving elemental sulfur within hydrocarbon wells are described herein. One method includes providing a solvent mixture including an elemental sulfur solvent fraction including disulfide compound(s), as well as an odorant fraction including a lactate ester solvent. The method also includes injecting the solvent mixture into a hydrocarbon well such that the elemental sulfur solvent fraction dissolves elemental sulfur deposited on well components, as well as collecting the resulting spent solvent mixture, which includes thiols and residual lactate ester solvent, within a spent solvent separator.

Abstract: The ?2-adrenergic receptor (?2AR) is a primary target in the treatment of airway diseases such as asthma and chronic obstructive pulmonary disease (COPD). Since ?-agonist treatment of airway disease can have severe side effects, compounds that attenuate the side effects of ?-agonists have been identified via their ability to inhibit ?2AR interaction with ?-arrestins. These compounds are specific for the ?2AR and effectively protect against the desensitization observed with ?-agonist treatment in model cells and airway tissue. The present disclosure provides compounds and methods for treating airway disease, such as but not limited to COPD and/or asthma.

Abstract: A profiler arranged to be used on a host vehicle. The profiler is capable of (a) receiving data collected by the profiler while traveling over a surface and (b) generating a surface profile using the data collected with no minimum speed requirement. Since there is no minimum speed requirement, the profiler is capable of generating valid, repeatable and reliable road surface profiles in situations not previously possible, such as during a stop, during acceleration of the host vehicle, during deceleration of the host vehicle, or while the host vehicle is traveling at very low speeds below thresholds typically required for prior profilers.
