presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction completed‚ affording the target product in high yield (70%). The structure of RH-PY was analyzed by 1H-NMR and ESI-TOF. Figure

In the short‚ “The Scarlet Ibis” the narrator quotes “It was bad enough having an invalid brother‚ but having one who possibly was not all the way there was unbearable‚ so I began to make plans to kill him by smothering him with a pillow” (Hurst‚ 2).

Her problem is then to Maximize: U = U (x‚ y) subject to the constraint B = p x x + py y Unless there is a Corner Solution‚ the solution will occur where the highest indifference curve is tangent to the budget constraint. Equivalent to that is the statement: The Marginal Rate of Substitution equals the price ratio‚ or px M RS = py This rule‚ combined with the budget constraint‚ give us a two-step procedure for finding the solution to the utility maximization

However the ordinary working capacity‚ which takes into account the typical breaks and the unmoving periods‚ is just 300 pies for each day‚ or 73 percent (as a rule 10 working hours for each day). That implies that the normal projected 176 pies for each day would be reached at just 60 percent of ordinary working capacity (176 pies/300 pies = .58)‚ which is a sensible target.
