Emulsion

Biochemical tests are used to detect the presence of different kinds of organic molecules, carbohydrates, lipids, nucleic acids, and proteins. These tests include the Benedict’s Test, Iodine Test, Sudan III Stain Test, Biuret Test and many others. With these tests, the nutrients from an unknown solutions can be identified in the solution. The Benedict’s test is used for identifying reducing sugars, which are simple sugars that include monosaccharides and some disaccharides. The Benedict’s…

of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion solvent evaporation technique. For optimization of stirring speed, the microspheres were prepared at various speed such as at 1250, 1500, 1750 and 2000 rpm. Out of these, at 1500 rpm gave the formation of well formed microspheres with maximum…

Form, structure, and plot: The Grapes of Wrath story structure split into two parts; One part is focused on a migrating family called the Joads and the other part was focused on a broader view of what was happening during that time period. The impact of structure is allowing the reader to have a better understanding of the hardships that the main characters went through. The even chapters in this book are from a view on the Joad family. This quote is within chapter 4: "Oh, I heard. Ma sent me a…

plate method for taking pictures that had been used for many years, which required a lot of equipment. He thought that there had to be an easier way to take pictures. So Eastman studied the method the British were doing which was using a gelatin emulsion on the glass plates that could be used after it dried. Eastman decided to take this method one step further. Instead of using glass plates, he used paper with the gelatin coating. Eventually, he created a roll of film that could be placed…

George Eastman had a lot of hardships throughout his life. His father, George Washington Eastman, moved the family from Waterville, New York, to Rochester to start the Eastman Commercial College (George Eastman). Tragedy struck two years after they moved, Eastman’s father died and the college went bankrupt. This horrible turn of events left George to take care of his mother, Maria Kilbourn, and two sisters (About George Eastman). One of which had polio (Hofkes). At age fourteen, he dropped out…

The mixture remained together therefor it is heterogeneous. You can visualize this mixtures kind because of the different sized grains and color. Test Tube E consisted of a clear and a yellow substance that did not combine. This is called an emulsion mixture since they are two liquids that do not normally combine. Because they cannot combine, they are heterogenous. By shaking Test Tube D, the two liquids look like they have combined into a light yellow substance, but soon after return to…

little bit the picture would turn out blurry. In the year of 1881 George Eastman started making dry plates (Dry plates were round disks that were used instead of film). Then in 1883, George Eastman created a thin strip of paper covered in gelatin emulsion and silver balide, which is what we call film. Finally, he invented the first hand held camera that did not need a tripod and only took less than a second to take a picture. He called it the Kodak camera and later came up with the Kodak…

is released clinging to mono, di, and triglycerides of fat globules, causing the fat globules to break up into triglycerides emulsion droplets. Pancreatic juice produced by pancreatic acinar cells contains a large amount of pancreatic lipase, the principal triglyceride lipase digesting enzyme. Pancreatic lipase molecules attach to triglyceride molecules of the emulsion droplets. Each triglyceride molecule is catalyzed and broken into monoglycerides and fatty…

and reassurance or create the impression of an angelic countenance. For example in the second image Flora appeared almost ghostly white in comparison to Gus who looks like he could be undetectable in a dark place. Replacing silver particles in the emulsion with colored silver salts causes low light sensitivity, which is responsible for the lighting in the movie. Costumes are also as important in the creation of the movie as it defines the character before they have the chance to open their…
