Problem 19E

The article “Cellulose Acetate Microspheres Prepared by OAV Emulsificatipn and Solvent Evaporation Method" (j(. Soppinmath, A Kulkarni, et al„ Journal of Microencapsulation. 2001:811-817) describes a study of the effects 0f the concentrations of polyvinyl alcohol (PVAL) and dichloromethane (DCM) on the encapsulation efficiency in a process that produces microspheres containing the drug ibuprofen. There were three concentrations of PVAL (measured in units of % w/v) and three of DCM (in mL). The results presented in the following table are consistent with the means and standard deviations presented in the article.

 PVAL DCM = 50 DCM = 40 DCM = 30 0.5 98.983 99.268 95.149 96.810 96.810 86.718 75.288 74.949 72.363 1.0 89.827 94.136 96.537 82.352 79.156 80.891 76.625 76.941 72.635 2.0 95.095 95.153 92.353 86.153 91.653 87.994 80.059 79.200 77.141

a. Construct an ANOVA table. You may give ranges for the P-values.

b.Discuss the relationships among PVAL concentration, DCM concentration, and encapsulation efficiency.

HY104 Class Notes from the Week of April 4 , 2016 I. Role of the U.S. Supreme Court a. Hirabayashi v. U.S. (1943) i. Gordon Hirabayashi, a Japanese American, refused to report for transportation to an internment camp. The Court upheld his arrest and conviction b. Koretmatsu v. U.S. (1944) i. Executive order ordering Japanese American interment was constitutional. the decision was deferred to the military and discussed wartime danger­ sacrifices must be made c. Endo v. U.S. (1944) i. The Court rules that the internment of loyal Japanese American citizens was unconstitutional II. WWII Diplomacy and the Origin of the Cold War a. War in Europe i. The big three alliances: U.S., Great Britain, Soviet Union 1. Churchill, Roosevelt and Stalin; leaders who met between 1943 and 1945 to coordinate attacks on Germany and Japan, and later to discuss plans for postwar Europe and settlement of Germany. After the war, their armies occupied Germany, each with a separate zone, although governed as a single economic unit. ii. Opening the Second Front in Europe 1. Stalin's wish for the western allies open another front in Europe in 1942 against the Germans to take the pressure of the Russians on the Eastern Front iii. Yalta Conference, 1945 1. FDR, Churchill and Stalin met at Yalta. Russia agreed to declare war on Japan after the surrender of Germany and in return FDR and Churchill promised the USSR concession in Manchuria and the territories that it had lost in the Russo­Japanese War b. War in the Pacific i. May, 1943: Japan controls Southeast Asia, Hong Kong, Singapore ii. June 1942: The tide turns 1. Battle of Midway a. United States Navy under Admirals Chester Nimitz, Frank Jack Fletcher, and Raymond A. Spruance decisively defeated an attacking fleet of the Imperial Japanese Navy iii. 1945: Iwo Jima and Okinawa 1. Okinawa: largest amphibious landing in the Pacific theater of World War II; resulted in the largest casualties for the Allies 2. Iwo Jima: U.S. Marines landed on and eventually captured the island of Iwo Jima from the Japanese Imperial Army during World War II c. The decision to drop the atomic bomb i. Background 1. Atomic bomb: weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of such heavy elements as plutonium or uranium. ii. Manhattan Project 1. a research and development project that produced the first nuclear weapons during World War II. It was led by the United States with the support of the United Kingdom and Canada. iii. Potsdam Conference 1. The Big Three met in Potsdam, Germany to negotiate terms for the end of WWII 2. each side would take reparations from its own occupation zone, divided up GER, created Council of Foreign Ministers; marked the end of wartime alliance

The answer to “The article “Cellulose Acetate Microspheres Prepared by OAV Emulsificatipn and Solvent Evaporation Method" (j(. Soppinmath, A Kulkarni, et al„ Journal of Microencapsulation. 2001:811-817) describes a study of the effects 0f the concentrations of polyvinyl alcohol (PVAL) and dichloromethane (DCM) on the encapsulation efficiency in a process that produces microspheres containing the drug ibuprofen. There were three concentrations of PVAL (measured in units of % w/v) and three of DCM (in mL). The results presented in the following table are consistent with the means and standard deviations presented in the article.PVALDCM = 50DCM = 40DCM = 300.598.98399.26895.14996.81096.810 86.71875.28874.94972.3631.089.82794.13696.53782.35279.15680.89176.62576.94172.6352.095.09595.15392.35386.15391.65387.99480.05979.20077.141a.
