Abstract: A cement slurry includes water, a cement precursor, a sliding ring polymer, and an additional polymer. A cured cement composition, such as a cement sheath, can be prepared from the cement slurry. A method for providing a cement sheath in a wellbore includes introducing the cement slurry to an area between a casing and a formation rock of the wellbore and curing the cement slurry injected to the area between the casing and the formation rock of the wellbore, thereby forming the cement sheath in the wellbore.

Abstract: Various technologies described herein pertain to enforcing control flow integrity by adding instrumentation when source code is compiled or binary code is rewritten. An indirect call to a control transfer target (e.g., in the source code, in the binary code, etc.) can be identified. Moreover, the instrumentation can be inserted prior to the indirect call. The instrumentation can use a bit from a bitmap maintained by a runtime to verify whether the control transfer target is valid. When an executable image that includes the inserted instrumentation runs, execution can be terminated and/or other appropriate actions can be taken when the control transfer target is determined to be invalid; alternatively, execution can continue when the control transfer target is determined to be valid.

Abstract: Various aqueous anti-pilling fabric treatment compositions are described. The compositions include one or more aqueous polyurethane dispersions or one or more acrylic polymers or both and a silicone. The compositions can be used treat fabrics, textiles and articles of manufacture made therefrom to impart anti-pilling properties to the same.

Abstract: A first compute server of a distributed cloud computing network receives traffic that is destined for a private application or service running on a server of a customer external of the distributed cloud computing network. That server is connected with the distributed cloud computing network through a network interconnect. One or more policies that are configured for the customer are used to determine whether the traffic is allowed to access the private application or service. The first compute server transmits the traffic to a second compute server of the distributed cloud computing network that has the network interconnect. The second compute server transmits the traffic to the server over the network interconnect using as its source IP address an IP address that is dedicated to the customer.

Abstract: Apparatus and associated methods relate to a rapid repositionable construction shelf. In an illustrative example, a repositionable construction shelf may, for example, extend along a longitudinal direction with intersecting opposing protrusions. The opposing protrusions may advantageously be configured such that the opposing protrusions may releasably couple the opposing arms to at least one adjacent vertical construction beam. The opposing protrusions may, for example, be positioned such that a distal protrusion is higher than a proximal protrusion such that the weight of the shelf urges both protrusions to frictionally engage with the vertical construction beam.

Abstract: An exercise and rehabilitation apparatus for exercising an extremity of a user. The apparatus includes a flywheel having a first side and a second side with a channel in the first side. The channel has a top edge near a planer surface of the first side. A lever, such as a pedal or handle, is adjustable in position and combined with an adjustment member. The adjustment member is movable within the channel between first and second positions. However, the adjustment member cannot be removed from the channel through a slot along the top edge. A locking pin, biased in an extended position, is combined with the adjustment member and is movable between the extended position and a retracted position. The flywheel includes a plurality of openings adapted to receive the locking pin in the extended position in order to secure the adjustment member at a particular location within the channel.

Abstract: A fuel container comprising an enclosure configured to extend and contract vertically, allowing the container to be in a fully extended state or a fully collapsed state and further capable of being within a motorcycle storage compartment.

Abstract: A system and method for the monitoring of ammonia in a fluid. The ammonia monitoring system includes an ammonia sensor that is configured to detect trace amounts of ammonia (NH3) in a fluid (i.e., gas or liquid) that is pumped through it in real time. The real time ammonia sensor includes an interferometer configured to track the amount of ammonia that is pumped into the real time ammonia sensor. The ammonia monitoring system, via the real time ammonia sensor, is further configured to detect ammonia levels in industrial poultry houses and provide electronic feedback to the building's ventilation control system.
