Final Draft: Slater vs Turkle How can Turkle’s concept of “authenticity” help us see Slater in a new way? Both face-to-face interaction and social networking sites (including Myspace‚ Twitter‚ and Facebook) are forms of staying in contact with friends and family. While Nora from Turkle’s “Alone together” communicates her engagement and wedding date via email to her closest friends and family‚ she could have easily announced it face-to-face‚ at a party or through a Facebook event.

CHEMISTRY 101.1 Intermediate Chemistry Laboratory I Institute of Chemistry University of the Philippines‚ Diliman I. Synthesis of Salicylic Acid Purpose: Part I of the experiment illustrates the base hydrolysis of an ester‚ methyl salicylate‚ to form salicylic acid through nucleophilic acyl substitution. Procedure: Dissolve 12 g NaOH in 70 mL water in a 150 mL round bottom flask. Add 5.0 mL methyl salicylate and reflux the reaction mixture at its boiling point for 15 minutes using a stirrer

Experiment #17 Classification of Chemical Substances Prepared for: Dr. Robert O’Reilly By: Kudaibergenov Baizak 20.11.2013 Nazarbayev University Introduction While many thousands of substances are known‚ they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances.

2.7 Raman spectroscopy Principle: Raman spectroscopy is based on the use of a laser light to induce oscillation and rotation in human fluids containing glucose. Because the emission of scattered light is influenced by molecular vibration‚ it is possible to estimate glucose concentration in human fluids [24]. This effect depends on the concentration of the glucose molecules. This technique can measure very weak signals‚ even in human fluids. The wavelength range of Raman spectrum is considered to
