A material may fail in many ways; in a ductile or brittle mode; by creep or fatigue; by corrosion or stress corrosion; by hydrogen or liquid metal embrittlement; by slow tensile overload or by impact. An examination of the failure may tell you a lot about the material and the failure mode. In this course, you...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
