Abstract: Solutions to the problems of scuffing and chipping of the paint films in high traffic areas and in tight spaces, such as dressing rooms in department stores, where multiple scrapings of the wall paints are created by consumers, clothes hangers, shoes, etc., and hallways and conference rooms in office and other commercial buildings are disclosed. Wax seeded latex polymers admixed with an added wax in architectural compositions and optionally with polyurethane resin are utilized to create paint films that are resistant to scuffing and chipping.

Abstract: In various aspects, methods and systems in accordance with the present teachings are provided that enable the tamponade of an internal hemorrhage site that can potentially occur during a closed, minimally invasive surgical procedure. In the unfortunate instance that an acute hemorrhage requires unscheduled conversion to an open surgery, the exemplary methods and systems described herein can enable the surgeon to prevent excessive blood loss from the hemorrhaged vessel during the conversion or repair process. Whereas in open surgeries hemorrhage is typically provided by a gauze sponge held by a set of ringed clamps (e.g., a sponge stick), the small diameter access ports through trocars used in minimally invasive surgeries can make it difficult to deliver sufficient gauze or other absorptive material to properly, temporarily occlude the hemorrhaged vessel. Moreover, because placing a clamp around the bleeding vessel (e.g.
