Snoring has long been considered an irritating but benign habit. However, "even isolated snoring might not be harmless," according to new research reported in the Forbes article "Snoring: A New Tip-Off to Stroke" (Haiken). The American Academy of Head and Neck Surgery defines snoring as "what you hear as a result of a form of blockage that obstructs the flow of air through the mouth or nose. The blockage causes the tissues of the airway to vibrate and flap." However, it is not the vibration and flapping of airway tissues that makes Henry Ford Hospital researchers Robert Deeb, MD, and Karen Yaremchuk, MD, so concerned. "Snoring can reveal damage to the carotid arteries-the arteries that supply oxygen-rich blood to the brain." In their study, Deeb and Yaremchuk found that the damage to the carotid arteries could be due to the trauma and inflammation caused by the vibrations of snoring. Deeb said that snorers should seek treatment since they could be at risk for coronary artery diseases. Deeb said, "Patients need to seek treatment in the same way they would if they had sleep apnea, high blood pressure or other risk factors for cardiovascular disease." Early detection of cardiovascular disease indicated by snoring can lead people toward an earlier diagnosis and treatment of heart disease. Deeb said, "Snoring is generally regarded as a cosmetic issue by health insurance, requiring significant out-of-pocket expenses by patients. We're hoping to change that thinking so patients can get the early treatment they need, before more serious health issues arise" (Haiken). Sources: "Don't Ignore the Snore: Snoring May Be Early Sign of Future Health Risks." Science Daily, 24 Jan. 2013, www.sciencedaily.com/releases/2013/01/130124122741.htm; Haiken, Melanie.

The two liquid products that Tampa Chemical makes - TC1 and TC2 - yield excessive amounts of three different pollutants: P1, P2, and P3. The state government has ordered the company to install and to employ antipollution devices. The following table provides the current daily emissions of each of the three pollutants, in kg / 1000 liters of product (kilograms per 1000 liters), and the maximum of each pollutant allowed in kg. Pollutant TC1 TC2 MAXIMUM ALLOWED P1 20 35 40 P2 10 15 20 P3 80 60 50 The manager of the Production Department has approved the installation of two antipollution devices. The emissions from each product can be handled by either device in any proportion. (The emissions are sent through a device only once, that is, the output of one device cannot be the input to the other or back to itself.) The following table shows the percentage of each pollutant from each product that is removed by each device. Device1 Device2 POLLUTANT TC1 TC2 TC1 TC2 P1 40 35 30 20 P2 60 60 0 0 P3 50 50 60 85 For example, if the emission from TC1 is sent through Device 1, 40% of pollutant P1, 60% of pollutant P2, and 50% of pollutant P3 are removed. Manufacturing considerations dictate that TC1 and TC2 be produced in the ratio of 1 to 2. Formulate a single LP model to determine a plan that maximizes the total daily production (amount of TC1 plus amount of TC2) while meeting governmental requirements.
