Sub-optimization can be defined as the process of fulfilling or optimizing some chosen objective which is an integral part of a broader objective; usually the broad objective and lower-level objective are different. It occurs when different subunits each attempt to reach a solution that is optimal for that unit‚ but that may not be optimum for the organization as a whole. For example‚ the quality control department of a factory may want to introduce a program that will guarantee that every bulb that

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic
