Abstract: Systems and methods of evaluating well cementation are disclosed. In certain embodiments, a tool is lowered into a casing surrounded by an annular material within a wellbore. An emitter of the tool emits an acoustic signal at a first pitch angle selected to excite a mixed-mode Lamb wave comprising a symmetric extensional (Sn) mode and an asymmetric flexural (An) mode of a Lamb wave in the casing. A receiver of the tool that is disposed at a first distance from the emitter receives a portion of the Lamb wave that has leaked from the casing at approximately the first distance.

Abstract: A system for containing and transporting a medical device may include a container including a bottom face and surrounding side faces as a closed first end and an open second end to form an inner portion for receiving and retaining the medical device. At least a portion of one or more of the side faces may have an indentation extending along a length of the respective side face. A liner and cover may be removably enclosable about the container. The liner may be extendable over the side faces to line the inner portion of the container. The cover may enclose the medical device in the container between the liner and cover. The indentation may be formed into the inner portion of the container. The container may be compatibly receivable in a first transportation device in a first orientation.

Abstract: A system for containing and transporting a medical device may include a container including a bottom face and surrounding side faces as a closed first end and an open second end to form an inner portion for receiving and retaining the medical device. The liner may be extendable over the side faces to line the inner portion of the container to an outer surface of the bottom face of the container. The liner may act as a protective barrier to the container to minimize contamination when receiving and/or retaining a used medical device. First and second covers may be removably attachable to the container, over the liner, to enclose a medical device therebetween. A first cover may have a color or marking indicating the medical device is “clean”, while a second cover may have a color or marking indicating the medical device is “used”.

Abstract: A system, method, and platform for automated and orchestrated software development and deployment are described. The platform automatically creates scripts for the target platform and orchestrates its execution. The platform receives source script, separates script commands from variables and values, determines source data and target data in the scripts, and stores them separately. The platform further creates a list of end functions (also referred to as tasks) to be executed on the target machine based on a given workflow and target machine data and provides orchestrated detailed execution scripts for the target machine. As one may appreciate, the platform provides an automated way to use an existing script written for one target machine to generate scripts for another target machine.

Abstract: A portion of an anisotropy formation through which a wellbore is formed can be identified. An estimate of an elastic anisotropy parameter for the portion can be adjusted based on a first quality control analysis using the elastic anisotropy parameter for the portion. The first signal representing the elastic anisotropy parameter for the portion. The estimate of the elastic anisotropy parameter for the portion can be adjusted based on a second quality control analysis using estimates for the elastic anisotropy parameters for two or more portions of the anisotropy formation.

Abstract: A heat exchanger within an insulated enclosure receives primary refrigerant at a high pressure and cools the primary refrigerant using a secondary refrigerant from a secondary refrigeration system. An expansion unit within the insulated enclosure receives the primary refrigerant at the high pressure from the heat exchanger and discharges the primary refrigerant at a low pressure. A supply line delivers the primary refrigerant at the low pressure to the load and a return line returns the primary refrigerant from the load to the primary refrigeration system. A system control unit controls operation of at least one of the primary refrigeration system and the secondary refrigeration system to provide a variable refrigeration capacity to the load based on at least one of: a pressure of the primary refrigerant delivered to the load, and at least one temperature of the load.

Abstract: The invention provides an apparatus for generating hydrogen including first and second reactant containers linked to a reactor vessel. The reactant containers contain reactants which, when mixed in the reactor vessel, react to form hydrogen gas. Peristaltic pumps pump the reactants from the reactant containers to the reactor vessel. The peristaltic pumps are selected to provide a maximum pumping pressure in the range from 0.1 bar to 10 bar. An electronic control means is programmed to control the flow of reactants to the reactor vessel so as to maintain the pressure of hydrogen gas within the apparatus at a value of no more than 10 Bar.
