The race to create the world’s first atomic bomb was a huge project that involved the work of tens of thousands of people and billions of dollars. Most of these resources‚ however‚ did not go into the theory of designing a bomb‚ as design was a relatively small part of the budget; rather‚ the money and manpower were needed to produce weapons-grade plutonium and uranium. Gaseous diffusion was‚ at the time‚ the most efficient way of separating the 235 U and 92 238 U isotopes.1 92 The question of

Separation of Proteins and Mass Analysis Using SDS PAGE Biology 00-01L Abstract This experiment consisted of separating proteins into polypeptides using a method called SDS PAGE which is a type of electrophoresis. The polypeptides had different masses‚ so each polypeptide traveled a different distance and this was an essential part of the lab which demonstrated that there exists a relationship between the distance traveled by the protein and the mass of the protein. This relationship was graphed

Separation Challenge Problem: Salt‚ sand‚ wood chips‚ iron filings Materials Needed: a magnet‚ water‚ a pot‚ clean flat surfaces‚ a burner‚ filter paper‚ a stirrer‚ and four beakers for each item in the mixture Plan Brainstorm: Separate the items one by one using their different properties. Final Plan: To separate sand‚ salt‚ wood chips and iron filings First‚ use a magnet to remove the iron. Since some sand/salt will get caught with the iron filings‚ you may have to spread out the separated

Throughout his novel‚ The Scarlet Letter‚ Nathaniel Hawthorne consistently uses the conflicting personalities of his main characters to augment the social and political instability of the Puritan community in which the work takes place. By focusing on the responsibilities and roles of a handful of important characters throughout the novel‚ Hawthorne is able to use them as examples of the hypocritical nature of the community’s beliefs. As a result of his implementation and analysis of characters

Soda Ash Analysis and Volumetric Analysis of a Carbonate-Bicarbonate Mixture De Guzman‚ Danica Justine R. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila Abstract Titration is a laboratory method in which the endpoint of a reaction is determined quantitatively. In this experiment‚ the amount of soda ash present in a sample was determined and the alkalinity reported as it was titrated using HCl as the titrant. Also‚ the percentage

6. Results and Discussion 6.1. Mix Design of Cold Recycled Bituminous Mixture Compaction characteristics of untreated bitumen mixes according to Modified Proctor Test is shown in Figure 6. When the RAP content increased‚ it resulted in reduction of MDD and the corresponding increase in OMC. The decreased MDD is obtained due to the weak bond between RAP and the virgin material and also due to less fine material that plugs the voids to produce denser mix. The corresponding increase in OMC is

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any
