Buffer Essay Topics & Paper Examples

New Building-Optical Networks

The new structure has been given a grant to make its network state of the art by making it a fiber optic network. The topics of discussion that will be mentioned in this paper are the hardware that will be necessary for the inside and outside of the building and how we would expand the fiber to an adjacent building if it is built. Another topic to be discussed will be describing the safety procedures that will be following during the installation. INSTALLATION HARDWARE PULLING EYE- When running a cable through a wall, conduit or other inaccessible space a pulling eye can be an indispensable tool. This device is specially designed to attach to the strength member of the cable…

Acid dissociation constant

1. Using the small ruler and the wax pencil, three markings are made on 3 test tubes. These markings should be at 1, 2, and 3 cm from the bottom of the tube. These tubes are then numbered by their pH values: 10, 7, 6, and 3. 2. One potato is chopped into small pieces and placed into a blender. 3. 125mL of distilled water is added to the potato. 4. This solution is blended on high just long enough to break open the cells, approximately 5 seconds. 5. This is then strained through 3 layers of cheese cloth into a beaker and kept cold in order to help prevent oxidation of the enzymes. 6. Each tube is filled up…

What is the role of 0.25M sucrose as the medium for the fractionation process?

1) What is the role of 0.25M sucrose as the medium for the fractionation process? Cold sucrose does not chemically react with cell organelles¬† Due to the density and size of sucrose molecules, it is able to suspend pellets for configuration while providing a solution where the centrifugation can be better balanced Sucrose offers a liquid medium in which less dense fractions can be poured off as supernatant at the end of each centrifugation step. 0.25M sucrose solution is isotonic and therefore inhibits the premature lysis of the mitochondria membranes during the fractionation process (centrifugation) 2) List the major components that are present in (a) pellet P1 and (b) Supernatant S2. Pellet P1 contains: Whole cells Cytoskeletons (i.e. plasma membrane)…

Mechanical Splice of Fiber Optic Cable

To prepare for mechanical splicing, make sure you have a clean, dry, and well lit work area. Do all your work over a fiber- optic mat and place any scrap optical fibers in their proper container. Before you begin splicing the fiber you want to make sure you have the following tools ready; Mechanical splice assembly tool, mechanical splice, buffer and coating removal tool, optical fiber cleaning fluid, lint- free wipes, and a cleaver. Once you have all your materials together proceed with the following steps: 1. Remove the mechanical splice from its protective packaging and load the splice into the assembly tool by pressing firmly at the ends of the splice. Do not depress the raised section on the…
