An Example of the Use of the Lagrangian Multiplier Method to Solve a Constrained Maximization Problem Let Q=output‚ L=labor input and K=capital input where Q = L2/3K1/3. The cost of resources used is C=wL+rK‚ where w is the wage rate and r is the rental rate for capital. Problem: Find the combination of L and K that maximizes output subject to the constraint that the cost of resources used is C; i.e.‚ maximize Q with respect to L and K subject to the constraint that vL+rK=C. Note that maximizing

The air-flow rate of flotation machine can directly affect the efficiency and quality of products. The main factors affecting the flotation machine air-flow rate can be summarized as the following:1‚ flotation machine impellers and cover the gap: the gap‚ the inflation decreases‚ but the gap is too small will cause the impeller and cover the impact and friction‚ and inflation fell. More appropriate for the gap of 5 to 8 mm2‚ flotation machine into the plasma volume: when the slurry into the impeller

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

Gabriel Alizaidy Liquid Chromatography September 14‚ 2009 Objective: To separate the components of unsweetened‚ grape flavored Kool-Aid. Procedure: Using two syringes‚ inject different concentrations of alcohol to extract red and blue dyes‚ and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography‚ resolution and selectivity played major roles in making the experiment work

component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance spot over the distance from origin to solvent front. As a result‚ the TLC analysis of Biogesic®
