were used on railcar components‚ specifically wheels and axles. A component to be examined would be dipped in brightly colored dye so that the dye could be absorbed into miniscule cracks in the part. After the surface dye was removed‚ the component would be powdered‚ and dye from the cracks would seep out to reveal defects in the material. This method is now known as dye penetrant testing. Early testing methods were crude‚ but as NDT technology became better‚ testing methods were able to detect

Abstract The activity of invertase and the quantification of albumin and casein were performed and analyzed after extraction of the said proteins from their respective sources. Isolation of proteins was initiated by the breakage of the cell wall / membranes in three different ways. Homogenization of invertase‚ albumin and casein were achieved via grinding process‚ addition of 1M acetic acid and acidification by 0.1M hydrochloric acid correspondingly. Extraction of invertase and casein involved

customer service expectations that requires high levels of inventory of finished garments. In this case Benetton does not dye the yarn or cloth before making certain sweaters‚ but the entire sweater when knowing the color demanded by the customers. After initial shipments of dyed sweaters are shipped to stores‚ the company receives information about the colors they are selling. Next they dye the remainder of their sweaters to more accurately meet the emerging demand pattern for the different colors. Value

Lasers and Their Uses We have all at some point in our lives used or seen someone use a laser. They are used in compact disc players for stereos or computers‚ laser surgery‚ laser printers‚ holography‚ cutting and borring metals‚ communication‚ bar-code scanners‚ etc. Over the past three decades’ lasers have become a tool used daily by many people and they have become very useful in scientific research. As you can see lasers are a very useful and important tool which is why I have chosen this

pH Indicators pH indicators are weak acids that exist as natural dyes and indicate the concentration of H+ (H3O+) ions in a solution via color change. A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic‚ basic‚ or neutral character of the substance you are testing. Introduction pH indicators exist as liquid dyes and dye-infused paper strips. They are added to various solutions to determine the pH values of those solutions. Whereas the liquid

moving fluid particle. To make a pathline visible‚ we might identify a fluid particle at a given instant‚ e.g.‚ by the use of dye‚ and then take a long exposure photograph of its subsequent motion. The line traced out by the particle is a pathline. On the other hand‚ we might choose to focus our attention on a fixed location in space and identify‚ again by the use of dye‚ all fluid particles passing through this point. After a short period of time we would have a number of identifiable fluid particles
