Lab 6 Report Part A 1. Run your model. Compare the queue statistics of the 3 processes with those obtained for Part C in the previous Lab. How have they changed and what conclusions can you draw? (Note the sums of all capacities for both cases are equivalent – 12 in each). The queue time and number statistics for the Air Jordan Logo operators and the Air Max Logo Operators were relatively close. The average queue length for the Air Jordan Logo operators was 0.03769112 in the previous lab

Butter lab 1 Introduction: While doing this experiment we used 3 terms. We used cream‚ butter‚ and butter milk. Cream is unhomogenized butter. Butter is what we got after the lab was finished. Butter milk is the milk around the butter after it is homogenized and it is thicker than normal milk. If we shake the cream in a jar than will it turn into butter? If I shake the cream than it will turn into butter because it will homogenized. In this lab you will shake a jar of cream and see if will

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying

to have in the body. A substrate is the material that is being broken down. In this case‚ the substrate would be hydrogen peroxide. The catalase‚ located in the liver‚ is being used to break down the substrate. Problem The purpose of this lab is to see if the enzyme‚ catalase‚ can be manipulated. We are testing the effects of pH‚ temperature and enzyme concentration. Hypothesis Controlled When we add peroxide to the liver it will bubble a lot and break down faster. When we add peroxide

Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can

Safety Concerns in the Laboratory Safety goggles must be warn at all times during a lab session. This is very important because they protect your eyes from harmful matter such as chemicals‚ glass‚ and fumes. It is very important to note that they must be goggles and not glasses. Safety glasses may protect the eyes from flying debris and splashes but may not protect the eyes from gas fumes or splashes from underneath. Also‚ wearing contact lenses in a chemical laboratory without proper coverage
