We’re supposed to record the color and texture. For the water test, we would have to stir and mix it with the foot powder. Next we would mix the foot power with vinegar and look for a gas production. After you would do the same to iodine with foot powder, but look for either a dark purple or blackish color after dropping iodine in the foot powder. Finally, you would do the heat test which
Safety valve was released and the rotor was turned until a stable (± 2min) that was appointed by needle pointer. Measurement was taken during storage days 1, 3, 7, 14, 21 and 28. Preparations of chloramphenicol eye drops Eye drop was intended as comparison preparations to find out the effectiveness of chloramphenicol hydrogel. The Preparations in accordance with the formula in Table 2. Antibacterial effectiveness test of chloramphenicol opthalmic hydrogel and eye drops against p. aeruginosa ATCC 9027 and s. pyogenes ATCC 19615 The purpose of the stage was to compare the effectiveness of antibacterial preparations in the form of hydrogel chloramphenicol against the form of eye drops.
1831- Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. This experiment became Faraday’s Law, which became one of the Maxwell Equations (Administrator, 2007). 1890 - Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. He laid the foundation for the future development of radio, telephone, telegraph, and even television.
2) Record the measured voltages, currents at different points and suggest about correct functionality. 3) Write down the detail report for testing the semiconductor circuits by using two different methods. Figure-1 DC Power Supply Circuit Figure-2 Single Stage Amplifier 3.1 Introduction This task was a part of unit 39- Electronic Principles; assignment -1 at Uxbridge College (UK) dated from 29/11/2013 to 20/12/2014 for second year students.
Some problems that might have occurred in the lab is that we either put too much ampicillin in our LB/amp/ara dish or we could have had all plasma and no bacteria. Something that was difficult for me personally was the disposing of the pipette tips when switching from different substances and pipetting the right amount. These difficulties might have caused me to make mistakes on the amount needed to pipette or the type of substance. Overall, next time I would have made sure to pay closer attention to the pipetting portion of the procedure. Furthermore, we could extend this experiment by trying different kinds of
The cause of this is likely that the protein was already broken down so much when used for cooking that Biuret’s test was unable to detect it. While the results from this experiment seem appropriate for the experiment, there could have been a few issues that could have taken place during the experiment. One of these could be that the solutions used for testing (such as Biuret’s solution) could have at out for too long since we did the experiment in the afternoon. This could lead to an incorrect data. Also, the materials may have not been completely clean, such as the test tubes, which could have also affected the data.
Summary Paragraph Children’s cough syrup is being recalled after the dosing cups have been incorrectly marked that was included in the package. The least toxic ingredient used in the syrup called guaifenesin. However, according to the labeled instructions; it’s unlikely to have any side effects and there were no reports on any serious side effects. Kids often get into these medicines, which may cause side effects, possibly hurting their health and parents worry about accidental overdoses. Opinion Paragraph I chose this paragraph because it was very odd to me.
For example, Kean spoke of how astronomer Tycho Brahe lost part of his nose and got a replacement silver one to curtail infections. The author also described how pioneers would keep their milk from spoiling by putting a silver coin in the jug. Like silver, the element copper is also oligodynamic. However, unlike silver, copper’s
The first test we conducted was the electricity test to see if the object was a good conductor of electricity. We turned on the electricity conductor that was hooked up to a battery and then placed the material on the plate. We observed the lit up lightbulb colors on the conductor in order to determine if it could or could not conduct electricity, the lit up colors were a bright red and dim green
