Lab‚ Week ASEPTIC TECHNIQUE AND BACTERIAL ANATOMY AND MORPHOLOGY Introduction Part I: Aseptic Technique The purpose of this experiment is to become familiar with the specific microbiological technique known as the aseptic technique‚ which is used to avoid contaminating cultures. In this case a pure culture of an unknown organism was introduced to a sterile medium of Phenol Red Glucose Broth Durham. The culture was obtained from a 52-year old male truck driver who is complaining

Mortel‚ Ferdinand METHANOLIC FRUIT EXTRACT OF Basella rubra Experimental t-test Basella rubra found to be an effective stain for normal blood cells. The use of methyl alcohol as extracting agent produces a better dye yield‚ and the correct ratio of blood to thedye was also identified. The dye was able to stain blood cells particularly red cells and even enhance withthe use of contrast reagents making white cells and platelets more visible. The study is limited to the ability of Basella rubra to effectively

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

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
