ISO-OSI 7-Layer Network Architecture This lecture introduces the ISO-OSI layered architecture of Networks. According to the ISO standards‚ networks have been divided into 7 layers depending on the complexity of the functionality each of these layers provide. The detailed description of each of these layers is given in the notes below. We will first list the layers as defined by the standard in the increasing order of function complexity: 1. Physical Layer 2. Data Link Layer 3. Network Layer 4

Column Chromatography of Plant Pigments Jaybee Balilea‚ Sharmaine Baysic‚ Maria Anjelette Patricia Belen 3Bio-7‚ Department of Biological Sciences‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column Chromatography is a form of solid-liquid adsorption chromatography and depends on the essential principles as does in thin layer chromatography. It was used in this experiment in separating and analyzing the different components of Capsicum frutescens (siling labuyo) with the use

Thin Layer and Column Chromatography of Extracted Total Lipids of Chicken Egg Yolk Aegan Matthew V. Amican‚ Karen Gem B. Ares‚ Ruvie Ann A. Ballester‚ Mark Joseph S. Barcelona‚* Katherine Carmen Isabel G. Calleja‚ Christelle Venus F. Capuno‚ Group 1‚ 2DPH‚ University of Santo Tomas Abstract Lipids are one of the major constituents of foods‚ and are important in our diet for a number of reasons. They are a major source of energy and provide essential lipid nutrients. This experiment determined

Column Chromatography of Plant Pigments Paul Ibarbia‚ Gene Paolo Jasmin‚ Gianpaolo Jimenez and Lorenzo Labicane* Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column chromatography of plant pigments is the separation of plant pigments extracted from Capsicum frutescens (siling labuyo). No slurry is prepared of the eluent; eluent with the stationary phase is set and then carefully poured into the column. The eluent are the solvents which are responsible for the

Research: The word density means the degree of compactness of a substance. There is density in everything in your everyday life (matter.)The formula to find density is d=m/v.The density of solids and liquids is usually stated as g/cm3‚ while gases are usually stated as kg/m3. A real life example of density would be that ice floats on water because it is less dense than water‚ or it sinks because it is more dense than water. The only substance that breaks this rule is ice. Archimedes was

Upon first examining the title of this poem‚ “The Layers‚” I predicted that the poem would be about a person’s “layers‚” such as their personality‚ and who they present themselves to be on the outside versus who they really are on the inside. After reading the poem‚ I found the title in the line “Live in the layers‚ not on the litter.” In context of the poem‚ I’d say this line and the title are using layers to represent different parts of our lives. Throughout the poem‚ the speaker is exploring and

Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis. With the

Throughout the lab I found out that both of the small and large silver rod‚ do not have the same density‚ and also found out that the gold rod is not real gold. My hypothesis is that since‚ the large and small silver rod has about the same density I believe that they would have about the same amount of volume. They both might displace the same amount

PHYSICAL PROPERTIES: DENSITY Introduction According to the definition Density is the physical property that allows us to compare the mass of substances for a specific volume. In this Lab activity that took place in Deree College‚ Agia Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids and liquids

10/1/13 Cubs Density The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.
