Abstract: The acid-induced steel corrosion inhibitor based on rotten eggs provides a corrosion inhibitor that is biodegradable, has low toxicity, is water-soluble, easily produced, and is low-cost through the use of waste material, namely, white eggs (EWs). The corrosion inhibitor is added to a corrosive medium in an aqueous medium to protect the metal surfaces and steel interfaces on metal production equipment, such as pumps, tubing, and casing. The corrosion inhibitor based on rotten white eggs is loaded with metal nanoparticles (EWMNPs). The eco-friendly less destructive corrosion inhibitors based on metal nanoparticles synthesized with rotten white eggs are efficient to protect steel from corrosion, while still dissolving in oil streams produced without or with salt water and being soluble in acidic mediums containing chlorides. The corrosion inhibitors have low toxicity to marine life when discharged into the ocean, thereby protecting the marine life, particularly near the system's drain.

Abstract: Aspects presented herein may improve the accuracy of uplink-based positioning when at least one network entity participating in the uplink-based positioning is operating under an energy saving mode. In one aspect, a network entity receives information indicative of a set of antenna panel configurations for a plurality of network nodes, where the set of antenna panel configurations is associated with a set of energy saving modes. The network entity transmits an indication of one or more UL-SRS transmission parameters for a UE based on the information indicative of the set of antenna panel configurations for the plurality of network nodes. In some examples, each antenna panel configuration in the set of antenna panel configurations may include a number of antennas to be used in an UL azimuth angle measurement and a number of antennas to be used in an UL elevation angle measurement under one energy saving mode.

Abstract: Provided herein is a novel silica-supported nickel nanocomposite and a novel one-pot solution combustion synthesis of that nanocomposite. The method allows the synthesis of small size nickel nanoparticles (e.g., 3 nm to 40 nm) for which a considerable percentage of nickel is inserted into silica, experiencing strong metal-support interaction. These exceptional physicochemical properties make them desirable for various industrial applications, such as electronic, heterogeneous catalysis as well as conversion and storage of energy.

Abstract: Examples may include techniques for using a sample clock to measure a duty cycle by periodic sampling a target clock signal based on a prime number ratio of a reference clock frequency. The reference clock frequency used to set a measurement cycle time over which the duty cycle is to be measured. A magnitude of a duty cycle error as compared to a programmable target duty cycle is determined based on the measured duty cycle and the duty cycle is adjusted based, at least in part, on the magnitude of the duty cycle error.

Abstract: Stimulation treatments are designed and performed in a manner that takes into account radial acid flow into the formation. A reservoir core plug is selected and a liner core flow test is performed. The core flow test comprises measuring a flowing fraction, injecting into the core plug a treatment volume of at least one candidate stimulation fluid at an injection rate at reservoir conditions, and measuring an effective reaction rate constant. The linear flow data are then scaled to radial flow. A skin, an acid concentration at a wormhole tip and a fluid velocity at a wormhole tip are calculated. A stimulation treatment is then performed. The method can also be performed on analog cores. The stimulation treatment may be matrix acidizing, fracture acidizing or acidizing natural fractures.

Abstract: Examples described herein provide for modeling acid flow for acid stimulation of a formation. An example method includes receiving data about the acid stimulation. The method further includes modeling, by applying the data about the acid stimulation to a model, a wormhole velocity of an acid injected into the formation during the acid stimulation, wherein the wormhole velocity is a function of a Darcy velocity of the acid. The method further includes determining whether the wormhole velocity satisfies a wormhole velocity threshold. The method further includes, responsive to determining that the wormhole velocity fails to satisfy the wormhole velocity threshold, modifying a stimulation parameter to adjust the wormhole velocity of the acid. The method further includes performing the acid stimulation based at least in part on the modified stimulation parameter.

Abstract: Virtual networks may be launched in a provider network with an initial IP address space (e.g., an IPv4 CIDR block). Methods are described that allow additional IP address spaces to be added to a virtual network. A new IP address space for a virtual network may be specified via an API. The specified space may be checked to insure that it does not overlap with IP spaces that are associated with the virtual network. If there are no overlaps, the space is added to the network, for example by adding the space to the network's route tables.

Abstract: Disclosed are various embodiments for automated testing of systems and applications. A computing device can be configured to receive a fault instruction specifying a fault to inject into one or more service requests sent to a service, parameters for the fault, and a duration of the fault. The computing device can then instantiate a service proxy and send a command to the service proxy, wherein the command specifies at least the fault and the parameters for the fault. Next, the computing device can cause service requests sent to the service to be redirected through the service proxy. The service proxy can receive a service request and generate a response to the service request that contains the fault based at least in part on the parameters for the fault. The service proxy can then return the response to the service request.
