Date report submitted: June 18‚ 2015 Title: Lab Techniques and Measurements PURPOSE: The purpose of this experiment is for the students to get a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure:

Alarms DeVry University NETW420 Alexander Davis Jun 1‚ 2014 This week’s assignment is to describe various event categories and event based transactions that are used by the Network Management System. It would be impossible to categorize all potential causes for alarms in all existing network systems however‚ understanding some common alerts and categories is essential for any network manager. Many Network Management Systems have a log and event manager that collects data

Cellular and Molecular Techniques - Lab #1 BIO 349 Lab Report #1 Microscopy and Staining Abstract The primary focus of this lab was on microscopy and simple stains. Microscopy that was used were magnification‚ slide preparation‚ and staining. Methylene blue‚ a simple staining component‚ was used to stain the slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24
