Laboratory Report - TDS Drinking Water Quality Report – Tap Water and Bottled Water Introduction: Since the human body is consisted of 60% or more of water‚ it is very important for everyone to pay more attention about the water quality. Water is extremely necessary for all living organisms. People all over the world rely upon water in almost everything in their lives. For example‚ we use water for drinking‚ washing‚ cooking‚ to grow our plants‚ and so far. Water is important for us so that

CE 314K Properties and Behavior of Engineering Materials Laboratory 4: Compressive‚ Flexural‚ and Tensile Strength of Concrete Lab Section: TH 2–5 PM Unique #: 15785 Lab TA: Janaki Vamaraju Solutions: 1.) In this lab‚ concrete cylinders and beams created from Lab 3 were tested for compressive‚ flexural‚ and tensile strength. The compressive strength of the concrete was found by applying an axial load on the cylinder until the cylinder failed. The flexural strength

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

China marker‚ I numbered test tubes 1-5 for identification purposes. Using a pipet I added 1 milliliter of each solution to it’s designated test tube. Next‚ I added 5 drops of the Biuret reagent to each test tube and agitated the mixture by shaking the tubes from side to side. After waiting 2 minutes I recorded the color of each mixture. I used the color reaction after adding the reagent to determine the presence of proteins in each substance (Mbuthia‚ 2012). Results Test solutions that contained

show the rate at which starch is broken down.1 This occurs when polyiodide chains are formed from starch and iodine. However‚ as starch is hydrolyzed into smaller carbohydrate units‚ the blue-black color does not appear. Therefore‚ using this iodine test‚ the effects of pH on the function of amylase can be determined by the time it takes (if at all) for the iodine to remain its orange-yellow color.2 Hypothesis Enzymes must be kept at certain conditions to function at its optimum level. Indeed‚ factors

Guilherme Schoenberger Project Management Harvard Extension School ASSIGNMENT 2 SCOPE CREEP IN PROJECT MANAGEMENT 1 1. INTRODUCTION 2 The concept of project scope may be one of the most ample in project management. It involves objectives‚ limits and intentions. Every requirement in a project as well as its characteristics must be dealt with when planning the scope. Even though it ’s reasonable to say that every project is unique‚ the causes for which it fails are generally the
