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 bout of hives usually lasts less than 6 weeks. These hives are called acute hives. If hives last more than 6 weeks, they are called chronic hives. Acute hives often result from an allergy, but they can have many other causes. The medical term for hives is urticaria (ur-tih-CARE-ee-uh). When large welts occur deeper under the skin, the medical term is angioedema (an-gee-oh-eh-dee-ma). This can occur with hives, and often causes the eyelids and lips to swell.
