Abstract: Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques of this disclosure may also be used to control the operation of the fall protection equipment based on the connection status.

Abstract: A downhole tool suitable for use in a wellbore, the tool having a cone, a first sleeve, and a lower sleeve. The downhole tool includes the first sleeve, or a portion thereof, disposed around one end of the cone. After activation, the lower sleeve is engaged with the first sleeve, leaving a remnant cone-sleeve component configured to plug a restriction.

Abstract: A system for stimulating a subterranean formation that has a wellbore formed within the subterranean formation; and a tubular disposed within the wellbore. There is a first frac valve disposed within the tubular, the first frac valve having a first sleeve in a closed position, and further configured to move to an open position. There is an at least a second frac valve disposed within the tubular, the second frac valve having a respective sleeve in a respective closed position, and further configured to move to a respective open position. A dart is configured to pass through the first frac valve without moving the first sleeve, and to subsequently engage the second frac valve to move the respective sleeve to the respective open position.

Abstract: Rice is described that is tolerant/resistant to herbicides, for example, ACCase inhibitors, and HPPD inhibitors, or both. For ACCase inhibitors, 2 different chromosome regions act synergistically in providing resistance/tolerance to the same herbicide class. Use of the herbicide resistant/tolerant rice for weed control and methods of producing tolerant/resistant rice are also disclosed.

Abstract: A system is provided, run on a liner, for stimulating one or more stages of a downhole wellbore. The system includes one or more frac valves arranged on the liner; each of the frac valves presenting an identical inside profile, the frac valves being openable for providing fluid communication between in inside of the liner to outside of the wellbore; and at least one dart deployable into the liner, and being adjustable to pass through one or more frac valves without opening said one or more frac valves, and to engage and open one or more other frac valves. Each of the at least one darts is identical to another. A method is further provided for stimulating one or more stages of a downhole wellbore.

Abstract: A method is provided for multistage isolation and fluid treatment of a borehole, in which a first frac valve tool and a second frac valve tool are provided, a first packer is mounted downstream from the first frac valve tool, a second packer is mounted between the first frac valve tool and the second frac valve tool, a third packer is mounted upstream from the second frac valve tool, at least one of the first, second and third packers being a hydraulic set packer having a single packing element, the first frac valve tool being moveable between a closed and an open position, the second frac valve tool moveable between a closed and an open position; running the liner into a wellbore; hydraulically setting the single element packers; conveying means for moving the first frac valve tool to the open position; and forcing stimulation fluid out through the first frac sleeve tool.

Abstract: A locking system for a door, such as a safe or security enclosure can include at least one locking pin bar assembly having flat locking pins or spades. The locking pin bar assembly is coupled to a lock mechanism by an actuator plate, which causes the locking pin bar assembly to extend outward into a locked position when the lock mechanism is actuated. The locking pin bar assembly includes a pin bar or flat plate that can be united with the one or more flat pins.

Abstract: A modular pod may include two or more walls, a roof, and a base, an air plenum, an air inlet, and an air economizer. The two or more walls, the roof, and the base may define a substantially enclosed interior space. The return air plenum may be positioned within the interior space.

Abstract: An application model build processor generates one or more application model build artifacts based on an application model. In one example, a method includes receiving inputs identifying application model subsets and audiences, and associating application model subsets with the audiences. The method further includes receiving inputs identifying semantic constructs of the application model with the application model subsets. The method further includes generating application model build artifacts based on the application model and defined subsets. The method further includes generating documentation topics for semantic constructs in the application model based on the semantic construct, the subsets to which it belongs, the audiences associated with those subsets, and other semantic constructs in those subsets.

Abstract: Mutant rice resistant/tolerant to ACCase inhibiting herbicides, in particular FOP herbicides, are listed in Table 1. The ACCase inhibiting herbicides used for selection include quizalofop. An exemplary mutant rice tolerant to an ACCase herbicide is disclosed, with a rice genome having G2096S or the equivalent, in the carboxyl transferase domain of the ACCase coding gene, using the Black-Grass numbering system. This mutation shows differential response to FOPs vs. DIMs herbicides, and a greater differential with comparable non-resistant rice lines. Methods to control weeds and methods to produce herbicide resistant rice including transgenic rice, are disclosed.
