Chapter 8: Aggregate Planning in a Supply Chain Exercise Solutions : We define a comprehensive set of decision variables that are utilized in problems 8-1 to 8-3 depending on the problem context. Decision Variables: Ht = # of workers hired in month t (t = 1‚..‚12) Lt = # of workers laid-off in month t (t = 1‚..‚12) Wt = # of workers employed in month t (t = 1‚..‚12) Ot = # of hours of overtime in month t (t = 1‚..‚12) It = # of units (000s) held in inventory at the end of month t (t = 1‚..

Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate this acid catalyzed

Acids‚ Bases‚ and Buffers Introduction: The pH scale is used to determine how acidic or basic a solution is‚ ranging from 1-14. The most acidic of all acids are at a pH level of 1 and the most basic of all bases are at 14. The neutral pH level is 7‚ which is what drinking water is. The pH level is determined by the amount of H+ ions present in a solution‚ and the more H+ ions there are the more acidic it is‚ and the lack of these ions results in more basic solutions. One distinguishing feature

Lab #2 – Assessment Worksheet Applying Encryption and Hashing Algorithms for Secure Communications Overview In this lab‚ you applied common cryptographic techniques to ensure confidentiality‚ integrity‚ and authentication. You created an MD5sum and SHA1 hash on a simple text file on a Linux virtual machine and compared the hash values of the original files with those generated after the file had been modified. Next‚ you used GnuPG to generate an encryption key pair and encrypted a message

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

Module 01 Lab Worksheet: General Review Introduction This week’s lab will focus on reviewing the concepts of anatomical terminology‚ metric conversion and genetics‚ specifically the concept of dominant and recessive alleles in a human pedigree. Objectives Objectives for this week’s lab include: 1) Review anatomical terminology‚ 2) Demonstrate metric conversion knowledge‚ and 3) Review the concepts of genetic inheritance and demonstrate knowledge of the inheritance patterns of dominant and recessive

and is a strong acid. Where comparing to the conductivity of distilled water to HCL would be evidently HCL. This is because distilled water doesn’t contain ions‚ hence no movement of electrons‚ furthermore no conductivity. However since we added sodium chloride‚ distilled water will have some conductivity but no where near the amount of HCL. Comparing to the conductivity of vinegar to HCL mostly relays on how acidic each other are. Since HCL is a strong acid and vinegar is a weak acid‚ this will impact

Kong Acid rain on plant -Background information Unpolluted rain is normally slightly acidic‚ with a pH of 5.6. Carbon dioxide (CO2) from the atmosphere dissolves to form carbonic acid. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition‚ which can appear in many forms. Wet deposition is rain‚ sleet‚ snow‚ or fog that has become more acidic than normal. Dry deposition is another form of acid deposition‚ and this is

Acid Rain Lab Report Introduction: The problem was to see how crushed chalk and whole chalk weather differently. The independent variables are The temperature of the liquids The surface area of the chalk‚ crushed vs whole The dependant variable was the weathering of the chalk; this was calculated by measuring the foam reactant. Procedure: Part B- For the two partners recording data with the room temperature liquids‚ the materials where collected first. Two of the graduated

effects that acid rain has or does not have on seed growth and germination. The observation gathered from this experiment was that regular rain water that has a neutral pH is a better solution for seed growth. The seeds that were watered with the well water prospered more than the ones grown in the lemon juice solution. The results from this experiment were a little confusing‚ because in the first trial the seeds watered with well water germinated more than the seeds watered with the acid rain solution
