2. TESTING OF INTACT ROCK FOR STRENGTH 2.1 Uniaxial Compression Recall the typical stress strain response curve for a specimen of intact rock under uniaxial compression (see Figure 1 in Lecture Notes 5). Pa rt OA represents the closing of existing cracks in the rock and an overall readjustment of the rock testing machine setup whereas part AB

Figure 1.2 The Griffith's experiment demonstrating bacterial transformation. A mouse remains healthy if injected with either the nonvirulent R strain of S. pneumoniae or heat-killed cell fragments of the usually virulent S strain. R cells in the presence of heat-killed S cells are transformed into the virulent S strain, causing pneumonia in ...
