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

Introduction A key cause of climate change is the failure of the market system to efficiently allocate resources to deal with extensive negative externalities‚ specifically those caused by carbon – based gases polluting the atmosphere. Failure in the market system is having a extravagant impact on atmosphere. The allocation of resources is affecting the environment but more specifically the carbon based gases are polluting the atmosphere. This is resulting in global climate change. Potential solutions
