Bridge Failure Studies and Safety Engineering 2.1 HISTORY OF DISASTERS AND SAFETY MANAGEMENT 2.1.1 Unexpected Material Deterioration and Failure Engineering is usually about avoiding failures and investigating why failures occur and ways to fix the problem. There is a need to understand the conditions giving rise to past failures and ways to avoid such failures so that loss of life can be minimized. Historical events and selected case stud-ies demonstrate the causes of

Ironically‚ the motto of this company was‚ “ask why” however this is perhaps the sole question that many employees are now asking themselves and should have routinely asked in the years

borehole. Thus differentiating brittle from ductile rocks has been the key to unique success in shale gas reservoirs. In the lab scale‚ The Brittle failure is occurred when the ability of the rock to resist load decreases with increasing deformation. Brittle failure is induced with materials that undergo little to no permanent deformation before failure and depending on the test conditions which may occur suddenly and catastrophically.

Situation: Two patients in their 70s present to the office at different times today‚ each with documented heart failure: one diastolic and the other systolic‚ and both are hypertensive. First‚ discuss the difference between systolic and diastolic heart failure‚ providing appropriate pathophysiology. ACEI/ARBs are the only medications prescribed for CHF that have been found to prolong life and improve the quality of that life. EXPLAIN the mechanism of action of ACEI/ARBs and how they affect morbidity
