Abstract: An existing concrete structure is repaired by covering at least a portion of the existing structure with a repair structure. Standoff retainers (each comprising an elongated member, fastener-receiving features and standoff-engaging curves) are mounted to the existing structure. Fasteners extend through the one or more fastener-receiving features and into the existing structure. Standoffs are coupled to the standoff retainers and extend away from the existing structure by extending the elongated members through apertures in the standoffs and locating each of the standoffs at a location of one of the standoff-engaging curves. Panels are coupled to the standoffs at locations spaced apart from the existing structure. Curable material is introduced to the space between the panels and the existing structure. The panels act as a formwork for containing the curable material until the curable material cures to provide a repair structure cladded by the panels.

Abstract: The disclosure concerns a method for assessing muscular dystrophy-linked protein expression in muscle fibers using digital image analysis of tissue. The method relates to assessing disease severity in individuals with muscular dystrophy. Muscle tissue samples are obtained from patients submitted for evaluation and processed to produce tissue sections mounted on glass slides which have been stained for a muscular dystrophy-linked protein. Digital images of the stained tissue sections are generated and analyzed by applying an algorithm process implemented by a computer to the images. The algorithm process extracts the morphometric and staining features of the muscular dystrophy-linked protein staining in the tissue, and parameters relating to these features are used to score the disease status for each patient submitted for evaluation.
