The True Meaning Behind that Layer of Blue Nail Polish When the red-based shades such as pink and orange were the only type of nail polish females dared to wear‚ I remember wondering if in the near future they’d dare switch to completely new shades such as blue or green. Now that day and age has come when all different shades of blue can be seen painted on teens’ nails. Yet‚ this new choice of blue isn’t just another craze of the moment. Rather‚ it symbolizes something slightly deeper

Briefing Thin-layer chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles

We spend hours surfing the net but yet we would fail to answer even a basic question on how internet operates? Thus‚ we would like to thank Prof. Ameya Shettye for selecting our group for such a project topic. It as been a very educational experience working on this topic and surprising how all the components

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

catalyzed Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure include; IR spectroscopy‚ thin layer chromatography (TLC)‚ and CHN analysis. A radical copolymerization reaction was conducted‚ with the initiation by radical initiator 1‚1’-azobiscyclohexanecarbonitrile. CHN analysis‚ IR spectroscopy‚ and Proton NMR analysis were used to prove its composition

To reduce the risk of imposters or masquerade or eavesdropping during the data transfer in a network‚ we also would have to implement Secure Sockets Layer (SSL) certificates are here to stand up to the risks. Using SSL encryption and authentication‚ SSL certificates have long been established as a primary security standard of computing and the Internet‚ and a no-brainer for securely transferring information

There is nothing more important in any business than securing your network topology from hardware‚ design and software. This plan is called network hardening and this plan needs to be incredibly detailed with how the network will be secured in each area. The first step to the network hardening plan resides in how you will build the network and then from there how you will secure each section of the network. This paper will discuss access control measures‚ encryption‚ PKI‚ certificates‚ OS hardening
