Wear safety goggles, apron and latex gloves. To start, mix 2g (weighed using a massing tray) of Nutrient Broth powder with 250 mL of deionized water. Using a pipette, fill each of the 50 test tubes with 5 mL of Nutrient Broth solution. Split the test tubes into two groups and two test tube racks. Label 25 test tubes as ‘2.4 GHz’, and label the second set of test tubes as ‘Control’ using a roll of tape and a permanent marker. Put all 50 test tubes in an autoclave and sterilize for 47 minutes. Inoculate each of the 50 test tubes with a 400 nL of E. Coli, and place caps on the test tubes . Put a set in an incubator at 37oC. Let E. Coli grow for 24 hours. Place 25 test tubes labeled “2.4 GHz” in the incubator with the Wi-Fi router. Place other

    Summary Recently a group of therapist administered the SAFER v. 3 to assess MM’s safety in her two-story home in Blue Bell, PA. After completing the assessment it was determined that MM has several areas that were deemed either “mild” or “moderate” problem areas. Much of this has to do with her intellectual disabilities or her mild CP, which causes her to toe walk. Of note, however, is the face that MM lives with her two parents and has an aide that comes to her home four times a week.

    The experiment overall was nicely conducted, and results were found through the information gathered. The dependent variable was established very quickly; furthermore, we can find the dependent variable was whether the athletes played a contact sport or a sport like baseball, where most concussions come from being hit by the ball. The independent variable is the number of concussions the test subjects obtained. Ultimately they could not control how many concussions each individual obtained but they controlled which individuals were chosen and what test were ran. The results that ran throughout the whole experiment was an overall success, the results show that multiple compared to single occurring concussions do not have an effect on P3 suppression.

    To do the temperature and dissolved oxygen tests, stick the probe in the water, and it will show numbers. One will be the dissolved oxygen in ppm (parts per million) and the other will be the temperature of the water. To do the pH test, stick the pH paper in the water and compare the color it turns to the scale. To test nitrates, put clear water in a container and dirty water in another, and put powder in them. Shake them and then compare the color they turn to the scale.

I also get to choose one of the four different allele frequencies that are allowed. I can mix and match the environment and frequencies however I want to. After picking an environment and a frequency, I then am able to move one generation forward. When I move a generation forward, the allele frequency will change.

    Polyester is synthetic fiber which mainly derive organic chemical compound from coal, air, water and petroleum and have the ester linkage. According to How (2015), the chemical reaction between an acid and alcohol formed polyester where a combination of two or more molecules form large molecule whose the structure repeats throughout its length. Researched by Smith (n.d) mentioned that production of polyester is by the chemical reaction of ethylene glycol with either terephthalic acid or its methyl ester in the presence of antimony catalyst to produce initially the monomer and low molecular mass oligomers. i. Starting from the acid: Direct esterification reaction.

    I. Introduction The purpose of this lab was to observe and record the bending stress and elastic properties multiple materials. A three-point bend is when a force is applied to the center of an object while it is supported on each side. This experiment was performed to record each material's flexural behavior so applications can be made with appropriate materials. The objective was to calculate the elastic modulus for each material tested. II.

    the objective function was Equation (1-4). The goal of this optimization was to achieve a situation of independent variables (field strength, retention time, power of ultrasound and sonication time), in which with the lowest energy consumption, the amount of E. coli in the sample is equal to zero. Boundary conditions specified in optimization was that the values of the independent variables are in the range of the experiment. All independent and dependent variables by reason of the same importance, the weight of one was given, and at the end, minimizing the value of the objective function was selected (Table 4-2). The optimum values for field strength, retention time, power of ultrasound and sonication time were equal to 10 kv/cm, 35s, 185.90 w, 4.47 min, respectively.
