In 500-750 words (not including the title page and reference page), develop an evaluation plan to be included in your final evidence-based practice project. Provide the following criteria in the evaluation, making sure it is comprehensive and concise: Describe the rationale for the methods used in collecting the outcome data. Describe the ways in which the outcome measures evaluate the extent to which the project objectives are achieved. Describe how the outcomes will be measured and evaluated based on the evidence. Address validity, reliability, and applicability. Describe strategies to take if outcomes do not provide positive results. Describe implications for practice and future research. Prepare this assignment according to the APA guidelines

Advanced optimization techniques are often necessary to solve real problems in health care. Techniques like goal programming and data envelopment analysis are often used to solve multiple objective problems, such as minimizing cost while maximizing access measures. Other advanced techniques are often required for problems that sometimes seem straightforward. Although you may not encounter the use of advanced optimization techniques on a day-to-day basis, understanding the methodology and application of these techniques is a valuable skill for the healthcare administration leader.For this Assignment, review the resources for this week. Reflect on, and consider, the advanced optimization techniques highlighted. Think about how you might apply these advanced optimization techniques to healthcare delivery challenges in a health services organization.For Chapter 14, problems 80 and 90, you will need to download the files P14_80.xlsx and P14_90.xlsx from the textbook companion website http://www.cengage.com/cgi-wadsworth/course_products_wp.pl?fid=M20b&product_isbn_issn=9781305947542. Under “Book Resources”, click on “Student Downloads” to view the downloadable files. Click “Problem Files” and download the zipped file 1305947541_538885.zip. Open the zipped file, and select folder “Problem Files” and then select folder “Chapter 14” to access the files P14_80.xlsx and P14_90.xlsx.The Assignment: (3–5 pages) Complete Problem 80 (pharmaceutical company) and Problem 90 (brain tumor) on pages 751 and 753 of your course text.Note: You will be using Excel and Solver for this Assignment.

14. A reaction was designed that produced either molecule A below or molecule B, both shown below. In order to decide which molecule was produced, the unknown molecule was reacted with sodium ethoxide in ethanol. Theproduct of that reaction was isolated as an {E} alkene only. Which molecule, A or B, gave the identified product? Draw molecules that explain your answer.(8 points) molecule A molecule B

4) RLC circuit (40 points) An RLC circuit has a resistance R = 100 9, an in—ductance L : 1H and a capacitor of unknown capac-itance C. After the capacitor is fully charged and thecircuit is closed a damped oscillation with angular speedwe 2 271′ f0 is observed, Where the frequency is f0 = 20 Hz. R L C a: What is the inductance C? (12 points) b: The energy stored in the magnetic ?eld within theinductor is maximal (5 points) 1. When the voltage reaches its maximum D 2. When the current reaches its maximum D
