CHAPTER 1: INTRODUCTION TO OPERATIONS RESEARCH (OR) 1.1 INTRODUCTION Operation Research‚ an approach to decision making based on the scientific method‚ makes extensive use of quantitative approaches to decision making. In addition to operation research‚ two other widely known and accepted names are management sciences and decision science interchangeably. The scientific management revolution of the early 1900s‚ initiated by Frederic W. Taylor‚ provided the foundation for the use of quantitative

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

Yield Data The reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

The Great War 1914-1918 was universally destructive. The effects of these were seen in many areas‚ as in the destruction of human life and property‚ and in the political‚ social and economic fields. The evolution of capitalism and progress in the scientific spheres were also important consequences. It is estimated that in the four years of war‚ some eighty lakhs of people were killed and as many wounded. Some 8-10 lakh people were reported missing. In most countries‚ after this Great War‚ monarchy
