This section of the tutorial explains exactly what is the final product of a Bedrock verification. Here and throughout the tutorial, we omit fully detailed formalizations, since the Coq source code already does a more thorough job of that than we could hope to do here.edrock is foundational, meaning that one needs to trust very little code to believe that a program has really been verified. Bedrock supports higher-order programs and specifications.
1 Widespread hives usually are caused by a viral infection. 2  Can also be an allergic reaction to a food, drug, infection, insect bite, or other substances. 3  Often, the cause is not found. 4  Hives from foods usually resolve in 6 hours. Contagiousness: Hives are not contagious. 2  Your child can return to child care or school if the hives do not interfere with normal activities. 3  If the hives are associated with an infection, your child can return to school after the fever is gone and your child feels well enough to participate in normal activities.
A. Hives, also known as urticaria, are an outbreak of swollen, pale red bumps, patches, or welts on the skin that appear suddenly -- either as a result of allergies, or for other reasons. Hives usually cause itching, but may also burn or sting. The most common causes are foods, medicines, latex, or infections. 2  Insect bites and internal disease may also be responsible. 3  The most common foods that cause hives are nuts, chocolate, fish, tomatoes, eggs, fresh berries, soy, wheat, and milk.
