(Greedy Heuristic аnd Optimizаtiоn Questiоns) A cоmpаny operates four plants that supply goods to five warehouses. The goal is to minimize the total transportation cost while meeting the demand at the warehouses and not exceeding the supply capacities of the plants. Plant Capacity (in units) 1 60 2 110 3 90 Warehouse Demand (in units) 1 80 2 50 3 60 4 70 Plant / Warehouse (Shipping cost, $) 1 2 3 4 1 10 13 12 11 2 15 14 17 18 3 19 16 20 21 NOTE: The question statement above is the same for all 3 questions in this exam. Question: The Capacity constraint for Plant 1 can be written as the following: x11 + x12 + x13 + x14 = 80

The patient has tried three attempts at easing the pain with GTN spray and when they did not resolve the pain he contacted emergency services as directed by his doctor. The 12 lead ECG performed in the Emergency department shows widespread concave ST elevation in leads V1-V4. A diagnosis of ST elevation myocardial infarction (STEMI) is made and the patient is referred for emergency percutaneous coronary intervention (PCI) . Please answer all parts of the question below. a) Explain the underlying pathophysiological mechanisms and the timeline of events that occur within the coronary arteries that lead to the patient experiencing an ST elevation myocardial infarction (STEMI). As part of your answer include an explanation of the role of serum cholesterol in the underlying pathophysiology of this condition. (60%) b) What is the purpose of performing a 12 lead ECG in patients with suspected ST elevation myocardial infarction and what is the significance of the ST elevation? As part of your answer you should highlight the difference in the presentation of STEMI, compared with other forms of coronary artery disease. (20%) c) What is the significance of the failure of the GTN spray to ease the patient’s symptoms? (20%)
