The author, Wilkes, of this journal article reviews and criticizes Charles Babbage and his engines. The title of the journal questions the current position Charles Babbage is known for, the father of computing. Wilkes considers Babbage a “great uncle” of computing science instead of the father and gives further details as in to why. The author doesn’t only criticize Babbage’s work but also informs the readers on how they operate and what their function is. According to the text, Babbage’s first

Selena Tran Chem 4A Lab Section 401 Formal Lab Report 1 09/21/2017 Gravimetric Analysis of Sulfate Formal Lab Report Abstract:     Three measures of unknown sulfate salt was measured and placed into three beakers with water, Hydrochloric acid, and Barium Chloride. The solutions were heated until Barium Sulfate precipitated and the solutions were filtered through ashless filter papers to collect the precipitate. The filter papers were combusted until only the BaSO4 remained, and the precipitates were

Mary and Max The first time I saw Mary and Max, I didn’t like it as it made me very sad. Mary and Max is a very deep bittersweet film about the friendship of two very incomplete souls. It brought tears to my eyes. The second and subsequent times I watch it, I begin to understand the film a little better and are made more aware of people with mental illness and their world. This world is a rather cruel place. When people do not fully understand something, they prefer to take the cognitive shortcut

service provider in the context of Indian cement industries by using Analytical Hierarchical Process (AHP). Not much research work is done in this area & in the cement industry sector. Hence, the findings of the current research will form the guidelines for the criteria’s on which the 3PL service provider should be selected. The steps involved in the AHP methodology are discussed in the following sections of the paper. 3.1 Analytical Hierarchy Process

Table 3.1: System suitability results for Ritonavir and Lopinavir Parameters Results Recommended limits Ritonavir Lopinavir Retention time 3.085 4.490 - Peak area 5184858 (%RSD – 0.1) 7196600 (%RSD – 0.3) RSD ≤1 USP resolution - 7.829 > 1.5 USP plate count 6171 8488 > 2000 USP tailing factor 0.979 1.063 ≤ 2 3.3.4 Assay of pharmaceutical formulation The proposed method was effectively applied to find Ritonavir and Lopinavir in their tablet dosage form. The results obtained for Ritonavir and Lopinavir

Chapter Five Discussion Extraction is a process by which substances and active constituents are separated from the original matrix, extraction process depends on many physical and chemical characteristics. Extraction is divided into two types liquid phase extraction and solid phase extraction depending on the physical phase of extraction agent(Rezaee et al., 2006). In our study, we have adopted liquid phase extraction for several reasons. Firstly, simple, inexpensive, relatively precise and wide

Sophie Tran Chem 15 Prof. Neumark Nov 30. 2016 Partner: Megumi Mori GSI: Erin Experiment #8: Quantitative Analysis of a Solution Containing Cobalt and Copper I. Abstract: II. Introduction: This experiment will help students to get familiar with Ion Exchange Chromatography (IEC) which is used mostly to separate unknown mixture of metal ions. Anion and cation are known as two types of IEC. This column chromatography contains two phase such as stationary phase and mobile phase. In this experiment

In this lab, paper chromatography will be used to separate the components of known and unknown mixtures and then used to identify those components. Paper chromatography is a technique where a drop of solution containing a mixture will be placed on a piece of filter paper. One end of the filter paper will then be placed into a liquid solvent. The mixture will separate into its different components as the solvent moves up the filter paper. The filter paper is known as the stationary phase. The solvent

INTRODUCTION A refractometer is aneoptical device that takes advantage of the fact that light passing through a liquid bends or refracts. The refractometer is a tool. It is used to help you select higher quality of foods containing more vitamins and minerals. They are also used to determine the concentration of dissolved solids in a solution. Cooking oil, molasses, syrup, and other thick liquids require a refractometerqcalibrated to read 30-90 Brix. Refractometer also is used in wine making. (Harrill
