discovered that the initial assumption that Yellow 5 and Blue 1 are in the Kool-Aid was correct. However‚ solely based upon the Rf values‚ the dyes in the green Kool-Aid are Red 40 and Yellow 6 as those are closet Rf value to the numeric data collected and calculated from the Kool-Aid chromatogram. However‚ the chromatography paper in both trials display that the dyes in Kool-Aid are a form of yellow and a form of blue because one color band was of a blue tint and the other‚ a yellow tint. Therefore

The solid was already in powder form therefore we did not have to crush it but it the unknown was in a tablet form‚ one would need to reduce it to a powdery-like form in order to perform this Thin-Layer Chromatography experiment.

The images presented‚ the Stele of Hammurabi and the Column of Trajan‚ are monumental examples of such propaganda. The Stele of Hammurabi is over 7 feet tall and was displayed in a public space. Trajan’s column was 38 meters high and displayed publically. It was important for propaganda to be seen by as many people as possible to be successful. More than just eye-catching‚ the monuments

Dear Madame Loisel‚ I received your letter about the issue concerning your friend’s lost necklace. According to your worried note‚ you had gone to a ball and wore your friend Madame Forestier’s expensive diamond necklace and lost it. The clasp had broken and you didn’t realize it had fallen off until you returned home. My advice to you is to contact the people who hosted the ball and have them look around or ask if anyone found a necklace. If you have no luck‚ be completely honest

Figure 1: Affinity chromatography of fumarase with the Ni2+-NTA-agarose column. Extract (9.9 mL) containing yeast (3.76g) in extraction buffer containing 0.1% Igapel CA-630 and protease inhibitors were pumped through Ni2+-NTA-agarose column. Fractions were collected by 1.5 mL portions by use of wash buffer (20.0 mL)‚ imidazole elution buffer (26.3 mL)‚ and wash buffer (10.0 mL)‚ again. Absorption readings were taken for all fractions with a Cary50 set at 280nm. The fumarase activity was determined

CIVIL ENGINEERING ABSTRACT This report describes a compression test on concrete columns. The main aim of the tests was to illustrate the ultimate strength limit state of reinforced concrete columns in combined bending and compression and to demonstrate the influence of slenderness on the ultimate load capacity. Test methods are described. It was found that the concrete columns exhibited complicated behaviour‚ and had a squash load point of 342.7KN and moment at 0 KN.m‚ a decompression

and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down are the different molecules that make up a certain color. Colors are basically made up of the primary (red‚ blue‚ yellow) and when you mix these colors together is when you get
