I’ve always wanted to dye my hair fun colors. My older sister Kayla used to dye her hair colors when she was in high school so I wanted to do it too. At the school I used to go to‚ you could not have any unnatural hair color‚ I couldn’t wait to get into high school so I could dye my hair. I asked and asked my parents for weeks over the summer if and when I could dye my hair. After a very long time of asking‚ they finally said I could. Since I didn’t want to be too expensive and go to a salon‚ I went

Theories of Staining Techniques Staining bacteria with different dyes via staining techniques‚ allows in distinguishing the microorganism from its backgrounds. Also‚ helps in studying different internal structures such as vacuoles‚ cell walls and spores in details (Seeley and others 1991). Some staining techniques such as Gram staining‚ endospore stain and capsule stain are some of the theories of stains used in bacteriology today. Also‚ these staining procedures help in determining properties

Acidic dye also recognized as a negative stain‚ is defined as a negatively charged dye‚ containing single or extra acidic clusters‚ like a sulfur collection. On the other hand‚ basic dye is a positively charged dye which is typically synthetic and reacting with negatively charged atoms What is the purpose of fixing a slide that is to be

rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water.

Denim and its various items like pants‚ shirts‚ jackets‚ belts‚ caps‚ etc‚ are the most preferred clothing for today’s youth. This study discusses compositions and methods of reducing or preventing back staining of indigo dyes on the weft yarn and pocket of denim garments. The dye‚ as it is removed from the denim material‚ post treatment with cellulase or by a conventional washing process may cause ‘back staining’ or ‘redeposition’ on the denim material; e.g : re-coloration of blue threads and blue

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

industry is a serious problem owing to the toxicity effect of wax‚ resin‚ sodium silicate and various types of dyes. Economical and efficient treatments are necessary for batik wastewater before it is discharged out. While treatment of dyes and chemicals are already available such as adsorption and membrane‚ it is observed that the presence of wax and resin can hinder the efficiency of dye removal using conventional technique. A study was initiated for the recovery of wax and resin using a baffle tank
