More particularly, the disclosure includes methods and sol-gel polymer composite compositions for creating a physical barrier on the teat surface or in the teat canal or cistern of a non-human animal for prophylactic treatment of mammary disorders such as mastitis wherein the sol-gel polymer creates a seal in response to one or more physiological stimulus.

Abstract: A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.

Abstract: A unique watercraft that includes a plurality of flotation elements which are aligned longitudinally and fit together end to end, comprising the watercraft hull. Unlike other watercraft, it does not rely upon a low center of gravity for stability. A front flotation element pivots about an axis and this pivotal motion is used for both steering and for maintaining balance. The effective profile of the hull changes dynamically as the front flotation element is turned. These hull changes allow the operator to balance and make agile maneuvers. Equilibrium can be easily maintained in this manner when the watercraft is moving forward and when it is otherwise stationary in water. In a preferred embodiment, the watercraft is ridden like a bicycle. Balance is actively maintained by a rider who steers right and left to adjust transverse weight distribution. The riding experience feels similar to operating a conventional bicycle on land.

Abstract: Systems, methods, and non-transitory computer readable media can obtain a user interface (UI) component of a production system, wherein the UI component is associated with one or more properties. Each of the one or more properties can be mapped to a graphical user interface (GUI) element for display in a user interface of a design application. A value of a property of the one or more properties can be set based on user input from a GUI element associated with the property. A rendering of the UI component can presented in the user interface based on the set value of the property.
