Temperature distribution in a thermal bridge This thermal image shows a thermal bridging of a high-rise building (Aqua in Chicago). A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, [1] creating a path of least resistance for heat transfer.

An assistance dog pressing a button to open an automatic door Hearing-assistance dog being patted on its head. An assistance dog is a dog that receives specialized training to aid an individual with a disability in navigating everyday life. Assistance dogs can be trained by an organization, or by their handler.
Assistance Dogs international serves as an international recognized authority on assistance dog programs [1] and authorizing organizations that are able to train dogs to assist with disabilities. This includes but is not limited to dogs for the visually impaired, hearing dogs, and service dogs for those with metal or physical health challenges. [2]
They stop the bridge from bending out of place in extreme conditions, and also allow enough vertical movement to permit bearing replacement [1] without the need to dismantle the bridge expansion joint. There are various types, which can accommodate movement from 30 to 1,000 millimetres (1.2 to 39.4 in), including joints for small movement ...
The narrow section at mid-span gives the bridge profile a slight arch shape making this design particularly useful when large headroom is required. The profile also makes the bridge more architecturally pleasing than a beam bridge. Rigid-frame design may be the most efficient bridge type for spans between 35 and 80 feet (11 and 24 m). [5]
In structural engineering, a rigid frame is the load-resisting skeleton constructed with straight or curved members interconnected by predominantly rigid connections, which resist movements induced at the joints of members.

Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special ...
