When the ink layer on paper is too thin, it is caused by less printing pressure and less amount of ink is transferred. The central position of plate cylinder is moved to change the pressure between the plate cylinder and the blanket cylinder. Center distance between…

prioritizing the continued security of the power grid should be at the top of the list. There are many different options that can improve security levels of both a physical and logical nature, such as disk drive encryption, digital certificates, Transport Layer Security (TLS), and Virtual Private Networks. Recommendation: Implement Full Disk Encryption Full disk encryption is the ability to convert data into unreadable code that can only be deciphered by authorized people. The encryption can…

Introduction Thin-layer chromatography, otherwise referred to as TLC, is a fast and inexpensive way to determine the amount of components in a solution or to identify an unknown compound. The principal behind TLC is when different compounds are placed on silica gel or alumina, (stationary phases) they will travel different distances when eluted with the proper solvent. According to ChemistryGuide, this is because the more polar compound has a stronger interaction with the silica gel due to its…

Investigation 13 “Who Wrote the Ransom Note?” Did The Sticky Bandit Make an Inky Mistake? Introduction: Early Wednesday morning at approximately 6:19 a.m. the widowed Mrs. Regina Butterworth realized when she went to make some syrup that her infamous syrup recipe had been stolen from her secret cookie jar vault. Mrs. Butterworth immediately called the police and upon their arrival they discovered a ransom note left by the alleged sticky bandit. The note was sent to the Tempe CSI Crime Lab…

The purpose of this experiment was to identify the generic name of the unknown drug through thin-layer chromatography analysis. By comparing the Rf values obtained from each TLC plate, it was deduced which components were present in the unknown drug. Through comparison of Table 1 and Table 2, Unknown A was identified as B.C. Tablets. Salicylamide was evident in the unknown substance due to the distinct blue color that was present in both the unknown spot and the salicylamide spot; the similar Rf…

would not have done anything to stop this type of compromise. The connection to server uses HTTPS pages that could use one of two secure protocols to encrypt communications (What is HTTPS, n.d.). The first is SSL (Secure Sockets Layer) and the second is TLS (Transport Layer Security) and both use what is known as an asymmetric Public Key Infrastructure (PKI) system (What is HTTPS, n.d.). With an asymmetric system it uses two keys to encrypt communications, a public key and a private key (What…

The variable located at the left side of the diagram, the effect of malunggay and ginger root extracts is the independent variable which in being manipulated for the dependent variable, the time spent in treating the sample infected by trichophyton rubrum. The main purpose of this study is to produce an organic antibacterial treatment for Trichophyton rubrum using Malunggay (Moringa oleifera) and Ginger (Zingiber officinale). Specifically, this study aims to answer the following: 1. In which…

The comparison of lining and interlining materials are given in Table 13.2 Table 13.2 Comparison of lining and interlining materials Sl. No Lining Interlining 1 It is used inside of garments or garment components. It is used between two layers of fabric. 2 It is attached by sewing. It is attached by sewing or applying heat and pressure. 3 Finishing is not necessary. Sometimes finishing is necessary to improve its properties. E.g. shrink resist finish. Crease resists finish. 4 No coating is used…

Text Data Computers represent information using bits. A bit string is a sequence of zero or more bits. This information is encoded by the sender and will be transmitted. The receiver then decodes the information. Data sent may be corrupted along the way because noise may interfere every time an information is transmitted to any channel. A channel is the physical medium through which information is transmitted. Examples of channels include telephone lines, internet cables, fiber optic lines,…

Beta-Carotene from Plant Leaves Yokoyama Yuri B1 (A0142349E) 1. Aim: a) To separate beta-carotene and chlorophyll via column chromatography. b) To analyse the contents of the plant extract as well as the separated beta-carotene and chlorophyll via thin layer chromatography (TLC) c) To analyse the absorption peaks of both beta-carotene and chlorophyll using UV-Vis spectroscopy 2. Results: Fig 1. UV-Vis spectroscopy results for S2 (Beta-Carotene extract) Wavelength at peak/ nm Peak obtained/ A…
