(or epityphlitis) is a condition characterized by inflammation of the appendix. All cases require removal of the inflamed appendix‚ either by laparotomy or laparoscopy. Untreated‚ mortality is high‚ mainly because of peritonitis and shock.[1] Reginald Fitz first described acute appendicitis in 1886‚[2] and it has been recognized as one of the most common causes of severe acute abdominal pain worldwide. Location of the appendix in the digestive system On the basis of experimental evidence‚ acute

PART I Brainstorming Identify the main themes.[1] In your notes‚ summarize the experience‚ reading‚ or lesson in one to three sentences. These sentences should be both descriptive yet straight to the point. Jot down material that stands out in your mind. Determine why that material stands out and make another note of what you figure out. For lectures or readings‚ you can jot down specific quotations or summarize passages. For experiences‚ make a note of specific portions of your experience

TOPIC – LINEAR PROGRAMMING Linear Programming is a mathematical procedure for determining optimal allocation of scarce resources. Requirements of Linear Programming • all problems seek to maximize or minimize some quantity • The presence of restrictions or constraints • There must be alternative courses of action • The objective and constraints in linear programming must be expressed in terms of linear equations or inequalities Objective

optimal solution of optimization problems. If the model has two variables‚ the graphical method can be used to solve the model. Very few real world problems involve only two variables. For problems with more than two variables‚ we need to use complex techniques and tedious calculations to find the optimal solution. The spreadsheet and solver approach makes solving optimization problems a fairly simple task and it is more useful for students who do not have strong mathematics background. The first step

Duality in Linear Programming 4 In the preceding chapter on sensitivity analysis‚ we saw that the shadow-price interpretation of the optimal simplex multipliers is a very useful concept. First‚ these shadow prices give us directly the marginal worth of an additional unit of any of the resources. Second‚ when an activity is ‘‘priced out’’ using these shadow prices‚ the opportunity cost of allocating resources to that activity relative to other activities is determined. Duality in linear programming

Introduction Linear optimization is a mathematical method for determining a way to achieve the best outcome such as maximum profit or lowest cost in a given mathematical model for some list of requirements represented as linear relationships. Linear programming is a specific case of mathematical programming The Primary Purpose of the present investigation is to develop an interactive spreadsheet tool to aid in determining a maximum return function in 401K plan. In this paper‚ we discuss how the
