In other embodiments, the present invention discloses methods of viscosifying a treatment fluid, suspending particulates in a treatment fluid, fracturing a subterranean formation, providing sand control in a section of a subterranean formation, and encapsulating treatment fluid additives. In yet other embodiments, the present invention discloses viscosified treatment fluids, fracturing fluids, gravel pack fluids, polymersomes, and encapsulated treatment fluid additives.
摘要:
While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.

摘要:
Certain examples provide systems, apparatus, and methods for content-driven healthcare location relationship management. An example method includes receiving one or more location identifiers for a content-based clinical application. The example method includes assigning one or more locations to a source role and a target role based on the one or more location identifiers and an ontology, the ontology including a plurality of relationship types. The example method includes identifying a relationship between the source role and the target role based on the one or more location identifiers and the ontology. The example method includes associating the source role and target role based on the identified relationship. The example method includes utilizing the source role, target role, and identified relationship to configure one or more content items forming the content-based clinical application.
摘要:
Methods and apparatus to manage instances of an enterprise clinical information system are disclosed. An example apparatus includes an instance tracker to obtain information related to a first instance of a clinical information system associated with a first healthcare entity of the clinical information system, wherein a plurality of instances of the clinical information system are installed in association with a plurality of healthcare entities of the clinical information system; an extractor to extract information related to a first application of the first instance of the clinical information system associated with the first entity and to extract information related to a second application of a second instance of the clinical information system associated with a second entity of the clinical information system; a dependency calculator to calculate dependency data of the first and second applications, wherein the dependency data indicates whether the first application is dependent on the second application; and an updater to, when the dependency data indicates that the second application is dependent on the first application, update the second application in response to an update to the first application.
