cooking and a “pastelon” which is a sweet yellow plantain dish‚ we can compare them in the preparation and the assembly of the dish while there is a difference in taste. These dishes‚ consist of ground beef and cheese‚ they are assembled in multiple layers‚ and I usually serve with white rice‚ salad or garlic bread. Sometimes I serve it with all three‚ but‚ in this case‚ I will compare them with salads as a side. Both the pastelon and lasagna have many similarities in a descriptive way but a difference

Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.

The evolutionary relationships among cyanobacteria‚ red algae‚ brown algae‚ green algae‚ and flowering plants‚ observed from the results their photosynthetic pigment patterns using thin layer chromatography technique Introduction Endosymbiosis is a process where unicellular organisms engulf other cells resulting a life form that one or both cells are dependent on each other (Campbell et al.‚ 2008). Strong evidence suggests that different types of photosynthetic cyanobacteria underwent endosymbiosis

◆ Bring in a can of spinach; a can opener (electric‚ if possible); small disposable bowls; and disposable spoons. Ask one student to act as the recorder again. ◆Have students name the five senses as the recorder lists them as column headings on the board. Then‚ use the can opener to open the can of spinach. ◆ Encourage students to share words that describe how it sounds. Spoon the contents of the can into bowls. Give each student a bowl containing a small serving of spinach. Ask students to describe

PAPER AND THIN-LAYER CHROMATOGRAPHY Lab 47 Michael Stravino‚ CHM 2211L‚ June 3‚ 2012 Abstract Thin-Layer Chromatography and Paper Chromatography can be used to identify identical compounds‚ unknown compounds‚ the number of components in a mixture‚ as well as other important uses not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of

composed of a thin‚ multi-layered organic film placed between an anode and cathode. In contrast to LCD/TFT technology‚ OLED does not require a backlight. How does an OLED emit light? • OLED’s basic structure consists of organic materials positioned between the cathode and the anode‚ which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film‚ which includes the Hole Transporting Layer (HTL)‚ Emission Layer (EML) and the

A successfully pollinated female flower started to set fruit after 2-5 diameters (Rodelina & Cleofas‚ 2009). Water spinach leaves are flat‚ and vary in shape depending on variety‚ from heart-shaped to long‚ narrow and arrow-shaped. The size may come up to 12 inches (30 cm) tall with trailing stems that are 7-10 feet (2-3 meters) long‚ but can get to almost 70 feet (21
