Damage indicators

Table 7-23 presents U.S. Atomic Energy Commission data [43], which expresses the overpressure above normal required to do the damage indicated. Table 7-24 presents a collection of industrial overpressure damage situations [53]. The overpressuring (P - Pg) is expressed [43] ... 

Butler and Ison S have suggested that variation in corrosion rate can be influenced by surface roughness, which allows a large number of nuclei for steam bubble formation. In these circumstances they have suggested that concentration of ions in solution next to the surface will be greater, and their observations on corrosion damage indicate that the steam bubbles may provide crevices or at least enhanced conditions for dissolution at the triple interface (solution/metal/steam).

An explosion rips through a chemical plant. A 1000-ft3 tank containing compressed air at 100 atm is suspected. Site damage indicates that the windows in a structure 100 yards away are shattered. Is the mechanical explosion of this compressed air tank consistent with the damage reported, or is the explosion the result of some other process ... 

P2 Most of the latter were associated with different types of DNA damage, indicating that DNA is one of the main targets for Cr inside the cell. The most prominent effect was on lacZ transcription from dinD promoter, which responded to all types of DNA lesion. RecA promoter... 

Diagnosing and rectifying an unstable catalyst standpipe operation can be extremely challenging. Poor standpipe operation leads to erratic catalyst circulation resulting in potential unit upsets, conversion and yield loss, and mechanical damage. Indications of impending catalyst circulation and standpipe problems include ... 

Two studies have examined the potential genotoxic hazard of occupational exposure to jV-nitrosodiethanolamine. The larger one, measuring DNA damage, indicated an association between single-strand breakage and the presence of A-nitrosodiethanolamine in...

Almost all field studies that have been carried out so far have demonstrated the presence of so-called residual DNA damage before sunrise. The occurrence of residual DNA damage indicates that damage induced during previous UV-B exposure events was not completely removed by the various repair pathways before a new UV-B exposure cycle (next day). 

Oxidative Stress A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and hpid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi). [NIH]...

Coal dust can lead to many health damages, such as pneumoconiosis, chronic obstructive pulmonary disease (COPD), cardiovascular disease, cerebrovascular diseases and acute respiratory infections (ARI), which all belong to diseases of the respiratory system. Therefore, the health damages caused by dust are classified into respiratory system related damage indicators.

Where a condition of combined fatigue stresses exists the application of uniaxial test data may not be directly relevant. Therefore, a rigorous design assessment will require a suitable test programme. However, as a conservative approach the damage indicator method given in the EUROCOMP Design Code will yield a safe result.
