Abstract: Computer-based methods and systems for facilitating assessment of results of genetic screening tests are provided. The methods and systems can be implemented to, for example, facilitate a risk assessment revision for a subject who may be a carrier of a genetic disease or facilitate a diagnosis of a genetic disease.

Abstract: A box scraper and scarifier has a scraper box and a mid-blade mounted to the scraper box, intermediate a scarifier bar and a rear wall of the scraper box. The scarifier bar, which can be either fixed or retractable, is also mounted to the scraper box. The scarifier bar includes a plurality of chisels for scarifying the soil. Positioned near the rear wall of the scraper box may be a rear cutting blade. Three actuators mounted to the box scraper and scarifier may be used to achieve a desired cut angle for either the mid-blade or the rear blade. Further, a front drawbar assembly and a rear wheel assembly may stabilize the box scraper and scarifier during use. In one embodiment, a shackle assembly attaches the box scraper and scarifier to a skid loader or tractor.

Abstract: A lock assembly includes radially movable engagement or latch members configured to engage a profile within a subsurface nipple, and further includes one or more sealing assemblies. The sealing assemblies are radially expandable by enlarging the interior of diameter of the elements of the sealing assembly, such as by placing a mandrel of relatively enlarged diameter through an internal diameter of elements of the sealing assembly.
