Abstract The objective of the south street seaweed experiment is to make a tincture of iodine. Iodine is used commercially as an antiseptic on cuts and scrapes of the skin. Conceptually, one of the active ingredients of the tincture, iodide, can be extracted from seaweed. By adding the seaweed to water and applying heat energy into the mixture, we were able to extract iodide. After adding Iodine salts, and filtering the mixture our next goal was to test for three important chemicals that must exist in our mixture for it to be a true iodine tincture; Iodine, Iodide Ion and the triiodide ion.
Akella Turnbull Date: February 2, 2015 Lab Partner: Shubh Rana South Street Seaweed Seaport Lab Summary: In this lab, we were able to make our own tinctures of iodine by extracting iodine from a Japanese seaweed, referred to as Fucus seaweed. We were able to conduct a hot water extraction from this seaweed in order to isolate the iodide, which is a solution that can be used to manufacture a pharmaceutical product. In order to prepare a tincture of iodine for testing we had to use a balance, ignite a Bunsen burner, and heat and filter a solution. In doing so, we had to prepare 6 grams of dry seaweed by cutting it into ½ inch pieces and placing it into a beaker filled with ¾ distilled water. Then after agitating the seaweed to remove monosodium glutamate and pouring off the water, 40 mL of distilled water was added to the seaweed and heated.
Stoichiometry is a section of chemistry that involves using the relationships between reactants or products in a chemical reaction to determine the desired quantitive data. 4. Using the balanced chemical reaction between Sodium carbonate and Calcium Carbonate given in page 92 of your lab manual (first paragraph of procedure), find the mass of Sodium Carbonate (in grams) needed in reaction?

This is an important issue due to the fact that biotechnology is heavily affected by capital availability and recently, venture capitalists were reluctant to fund biotechnology firms. As Jeff Hirst said, “When it comes to raising capital today, it’s a buyers’ market.” Therefore, producing returns for our current investors and producing high returns for potential buyers was a key focus. A second key issue was the probability of successfully completing each phase of testing. For both Phase I/II and Phase III, if the phase was not completed, there would be zero sales and all capital expenditures would be rendered useless. Phase I/II seemed relatively routine; however, Phase III was much more complex and presented a much bigger risk of preventing FDA approval and eliminating all future sales.
Discussion & Conclusion In this experiment we learned how to synthesize the cyclohexene by dehydration of cyclohexanol. We procedure the first step where we have to mix the components. Then we heat the R.B.F with a fractionating column, distilled water. Then we obtained the layers, and we transferred the organic layer to a small, dry Erlenmeyer flask. We added anhydrous Sodium Sulfate as a drying agent.
However, the risks of profit lead research can be seen in Southam’s experimentations and skin cream products today. What researchers need to do is find a balance between the two. Keywords: altruism, conflict, HeLa, moral, profit, science Conflicts of Altruism to Profit Over the course of several centuries, research has been conducted to better human understanding. Modern science has advanced in its ability to benefit society due to the numberless experiments and research conducted by scientists for either altruistic or profitable reasons. These two often contradictory forces greatly influenced HeLa related research.
The Silence of the Limpkins by Susan Cerulean is about the overall degradation of Wakulla Springs. This story begins with the narrator describing how his colleagues and he have to put herbicide in Wakulla Springs every so often. As to clear the hydrilla, a plant imported from India because of a trade that overall massively impacted the Wakulla Springs ecosystem. “Hydrilla was imported to the United States from India for the indoor aquarium trade in the 1950’s. No one knew it would become a major invader of Florida’s lakes and rivers” (Susan Cerulean).
Merchandise created by Livestrong stood for hope and victory, something that resonates with its audience. Following the Lance Armstrong doping scandal, and Livestrong cutting ties with Armstrong, the company transitioned into a period of rebranding. The first steps of the rebranding strategy involve hiring new celebrity ambassadors in actress Christina Applegate and NHL Hall of Famer Mario Lemieux. This would give the organization two recognizable and popular spokespeople that have survived cancer and would help with the transition from Armstrong. Along with the
Kudler Fine Foods Business Proposal December 15, 2008 Ashley Williams Kudler Fine Foods Career Development Plan From the beginning, Kudler Fine Food’s main goal has been to combine the convenience of one stop shopping with reasonable prices for customers. Although, Kathy and Kudler Fine Foods has been successful at achieving this goal, my team and I would like to take it a step further and help this company become even more successful than before. With the range of departments in the one-stop shopping center including baked goods, meat and seafood, produce, cheese and dairy, and wine, we feel the only thing missing is the morning perks……coffee! With a broad range of coffee, cappuccino’s, and latte’s,
