Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils. It did great job at pulling stains right out of the cloth. This products

There can be intentional stains (such as wood stains or paint)‚ indicative stains (like food coloring or adding a substance to make bacteria visible under a microscope)‚ natural stains (such as rust on iron or a patina on bronze)‚ and accidental stains (like spilling ketchup on your shirt.) While the types of stains are very different in application‚ they all form in the same basic ways: The primary method of stain formation is surface stains‚ where the staining substance is spilled out onto the

The acid-fast stain is performed on samples to demonstrate the characteristic of acid fastness in certain bacteria. Acid fastness is a characteristic that is shared by just a few organisms‚ so staining to determine if organisms possess this trait is useful in microbial identification schemes. The Ziehl-Neelsen method has endured as a reliable and effective way to demonstrate the acid-fast bacteria. Materials: 18-20 nutrient hour agar slant culture of Staphyloccus aureus 4 day old nutrient

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

Responses to the Black Plaque Gabriele d’Mussis initially explains the causes of the plaque to be “as though arrows were raining down from heaven to strike down and crush the Tartars’ arrogance”. Gabrielle’s understanding of the causes of the plaque changes as he traces its movements from East to West. He explained how when they would throw the decease along the sea it would eventually poison the water supply. When one person becomes ill‚ it was only a matter of time the next person. Everyone

C. Calculus Formation Relationship with Plaque: * Calculus is formed by the deposition of calcium and phosphate salts in bacterial plaque. These salts are present in salivary and crevicular fluids. * Plaque mineralization begins within 24-72 hours and takes an average of 12 days to mature. * Calculus contributes to the disease by providing foci for plaque accumulation. It is not the causative or etiologic factor‚ plaque is. * Calculus is porous and can act as a reservoir or nidus

While I was reading “In the Wake of the Plaque”‚ I was not sure at first whast the purpose of the story was. After I read the whole book‚ I figured out that the Plaque is simply an epidemic that kills off a huge percentage of the population in England. It is said that the plaque was brought into the area through rats. It kind of shocked me when they said rats but then again the rats were infected which infected the population because of the all of the shipments that come on and off the ports. Now
