blot as much urine up as you can- if it's still wet (doesn't matter) mix vinegar & water in a spray bottle (40/60 or any strong combo will do)- soak entire area. let sit a while then coat with baking soda- let sit again. scrub with hand brush- take up with paper towels.
Hernia mesh is a product which is used in hernia repair. It is made from implant-grade plastics which are formed into a grid which can be used at the site of a hernia to hold herniated organs in place and provide a lattice for new tissue to grow on, effecting a long term repair at the site.
A mesh network is a network built from devices that all work together to distribute all the data. They can be wired and use an algorithm like shortest-path bridging to efficiently route data through the whole network using cables and routers on certain nodes (a node is an address on a network), but they really shine when they are wireless.
