Failure dished

Brittle failure of the dished end of a 50 ton horizontal pressure vessel released anhydrous ammonia vapors which caused the explosion to occur. 

Allow the top collagen containing the explants to fully gel (usually 5-10 min) before moving the culture dish to the tissue culture incubator. Failure to allow collagen to fully gel... 

Wind and seismic activity can cause microwave dishes to go out of alignment. Earthquake-resistant towers and mounts can help prevent alignment failure, even for wind-related problems. Redundant systems should be considered part of your solution. A duplicate microwave system might lead to a false sense of security. Consider a nonmicrowave backup, such as fiber, for a primary microwave link. Smoke, heavy rain, and snow storms can cause enough path loss to disable otherwise sound wireless systems. 

Thermal stability Cells can undergo two types of thermal stress. The first is from being placed in a hot environment, whether that be leaving your laptop in a car on a sunny day or by placing your phone next to a hot dish on the table. In addition, most t)q)es of failures in a cell will generate internal heat, and the thermal stability of the separator can be a key determinant to how well the cell is able to withstand the heat without undergoing thermal runaway. 

More commonly, obesity can be attributed to a psychological failure of appetite control. At its simplest, this can be blamed on the variety of attractive foods available. People can easily be tempted to eat more than they need, and it may take quite an effort of will-power to refuse a choice morsel. Even when hunger has been satisfied, the appearance of a different dish can stimulate the appetite. Experimental animals, which normally do not become obese, can be persuaded to overeat and become obese by providing them with a cafeteria array of attractive foods. 

All weldments in a reactor contain high residual stress and, unless they are suitably stress-relieved, they are focal points for environmental cracking. However, the circumferential welds by which nozzles are attached to the vessels are particularly vulnerable. The radius of a dished head also contains residual stress from the forming operation, and the top head is often the first point of failure when volatile species (e.g., traces of hydrogen or ferric chloride) are involved (Fig. 12.5) [7]. External jackets can cause problems, unrelated to the process, that arise from the use of cooling water or steam in the jacket which causes external SCC of the vessel projjer.
