the point where the local tensile is a maximum. Stage 2: Crack Propagation (Fatigue Zone) – Cyclic tension stresses spread the crack. If the part breaks in one application of the load‚ without the cyclic action‚ it is known as static failure. Stage 3: Final Fracture (Instantaneous Zone) – Crack lengthens‚ decrease in load support‚ final failure. 3. How is fatigue in metals recognized? Fatigue in metals is recognized through the investigation of the fatigue zone. From the investigation‚ we are able

| Lysozyme activity | Observed in tears and saliva | | Connie Jamieson | 3/1/2012 | | Abstract Lysozyme is an enzyme found in both tears and saliva. Each time we blink our eyes‚ our eyelids wash tears over the surface of our eyes. In addition‚ our mouth is continually producing saliva. A spectrophotometer set to 450nm was used to measure the effect of lysozyme on bacteria. The absorbance or optical density was measured for each sample at specific times with a total measuring time of
