national chemical engineering school in 1904. In 1909‚ this young chemist founded the company L’Oreal. He had an amazing “entrepreneurial spirit”. Schueller began by selling his own formulated hair dye to the Persian Hairdressers. The next year after that‚ he convinced Paris hair stylist to use his hair dyes for a fashion show‚ with his determination and ambition he succeeded and earned publicity. Another bit of information that we know is that Schueller had a passion for chemistry always trying new

plant biology‚ aiding this study are the fundamentals of histology and techniques in histochemistry. This experiment involved exercising free-hand sectioning techniques‚ learning maceration procedures and application of staining techniques. Sudan dye for Lipids and IKI test for starch were applied on section stem‚ root and leaf parts of Tridax procumbens. Stem cross-section of T. procumbens showed distinct ground tissues and fourteen to sixteen vascular bundles organized into a ring. The root

What will happen when you put a drop of water on wax paper? I think that it will just sit there and do nothing. First I put a drop of water on the paper Second I watched it to see what it will do Finally I wrote down that it just stayed still My hypothesis is correct What will happen when you move the water around with a toothpick? I think it will go flat and dissolve in the in the wax paper. First I picked up the toothpick Second I moved the water around with the toothpick Finally

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

the ability of bacteria cell wall to retaining the crystal violet dye or methylene blue. The cell walls for Gram positive microorganisms have a higher peptidoglycan and lower lipid content than gram negative bacteria. Bacteria cell walls are stained by the crystal violet. Iodine is then added as a mordant to form the crystal violet and iodine complex so that the dye cannot be removed easily. This step is usually called fixing the dye. However‚ the next treatment with a decolorizer‚ which is a mixed

Information of Michael King’s lab sheet can state two conclusions. The first conclusion that can be stated from information of the lab is water seeped through some of the oil. The density of the water was 1.1 g/mL and the soap was 1.446 g/mL‚ the soap was clearly denser than water. For proof that the water seeped through the soap Michael King’s observation sheet of water stated: “The water is leaking down into the soap‚ but still sits on top of the dish soap.” Later through his observations it elaborates

practical is to investigate the effects of different treatments on photosynthetic electron transport by using isolated chloroplasts from silverbeet leaves. As photosynthesis proceeds‚ any electrons produced will reduce the dye DCPIP to its colourless form‚ so a rapid decrease in dye colour will indicate a rapid rate of photosynthetic electron transport. Given this‚ I predict that placing the reaction in the dark will produce no change in colour as well as the treatment of adding DCMU‚ as it is an inhibitor

as weddings‚ festivals or even births. Here‚ in the United States people often use it as tattoos. Since henna is not permanent‚ some get it to see how it will turn out before getting the actual tattoo. Another way to use henna is using it as a hair dye. It prevents breakage‚ it reduces dandruff‚ hair is thicker‚ it promotes growth because it has antibacterial and antifungal properties‚ and it also smooth’s the hair cuticle‚ giving hair healthy appearance. Henna is safe at any age and is mostly used
