The significance of the title in decoding what is in the artist’s mind lies in the little details in the painting itself. The noun “layers” indirectly draws the viewer towards a picture covering a piece of material -- the tudung. What then does the title represent? It seemingly explains about the lessons that the artist had to learn or is in the process of learning while discovering

the Experiment: The intention of the experiment is to use solvent extraction methods to separate a mixture containing a carboxylic acid and a neutral compound. Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving

spectra it is possible to identify which peak correlates with which compound. Figure 2 contains a peak at around 500 and 700 nm which is a good indicator that that would-be chlorophyll b. This makes sense because this was the bottom band from the thin layer chromatography and chlorophyll b is the most polar compound. Chlorophyll B contains an aldehyde where chlorophyll A has a methyl group making it slightly more polar. Following that‚ figure 4 contains

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.

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Analyze the layers of security for General Aviation When someone uses the term general aviation (GA)‚ most think about a small single engine plane flying over a field or giving site seeing tours. However‚ after 9/11‚ that perception changed and people started to realize that small general aviation aircraft could be used to carry out future terrorist attacks. There have been many layers of security set in place to reduce the chances of an attack happening‚ which has proved to be effective in keeping

OSI Layers 1) Physical Layer: The physical layer is at the bottom of this model. It deals with crude data that is in the form of electrical signals. The data bits are sent as 0s and 1s. 0s correspond to low voltage signals and 1s correspond to high voltage signals. The mechanical aspects of communication‚ such as wires or connectors come under this layer. The physical layer also deals with how these wires‚ connectors‚ and voltage electrical signals work. Also‚ the process that is required for

There are three basic layers of a blood vessel: tunica interna‚ tunica media‚ and tunica externa. The inner lining of a blood vessel that comes into direct contact with blood is the tunica inerna. In this layer blood flows through the blood vessel in a tube that forms‚ this tube is called the lumen. There are three layers of the tunica interna: the innermost layer is called endothelium‚ the next layer is called the basement membrane which provides support for the epithelial layer which is made from

EXPERIMENT 15 Thin-Layer Chromatographic Analysis of Drug Components Experiment Objective: To identify the components of an analgesic drug tablet and then correctly identify the tablet from a group of others with acquired data. Experiment Summary: In this experiment‚ we use TLC to identify components of an unknown analgesic drug. We prepare a solution of the drug by dissolving part of a tablet in 1:1 ethanol/dichloromethane‚ then spotting a TLC plate with the solution along
