Abstract: A sucker rod guide for use in a well production tubing, the sucker rod guide comprising: (a) a sleeve member, including a first material having a first wear characteristic and including: (i) a passage therethrough for a sucker rod; and (ii) an outer surface; and (b) a wear member overlaying the sleeve member and including a second material having a second wear characteristic, the wear member being fixed in position relative to the sleeve member and including: (i) an inner surface; and (ii) an outer surface defining a flow path for a fluid, when in use, between the sucker rod guide and the well production tubing.

Abstract: Particular embodiments described herein provide for an electronic device that can be configured to allow for the mitigation of ransomware. For example, the system can determine that an application begins to execute, determine that the application attempts to modify a file, determine a file type for the file, and create a security event if the application is not authorized to modify the file type. In another example, the system determines an entropy value between the file and the attempted modification of the file, and create a security event if the entropy value satisfies a threshold or determine a system entropy value that includes a rate at which other files on the system are being modified by the application, and create a security event if the system entropy value satisfies a threshold.

Abstract: A method for cross-linking an uncured or partially-cured epoxy resin system, the epoxy resin system including at least one epoxy compound, the epoxy compound including at least one glycidyl chemical group attached to at least one aniline chemical group, the process including: providing the epoxy resin system with at least a portion of the epoxy compound in contact with a PVDF-containing polymer in a diffuse mixture or at an interface; and cross-linking at least a portion of the epoxy compound with at least a portion of the PVDF-containing polymer, and in the same process step curing the epoxy resin system, to form a cured epoxy resin system having a cross-linked interface with a PVDF-containing polymer.
