Houston 3s Fibre Experiment Report

Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.

40) A sixty-minute timer was started to see how the 9 Na⁺Cl⁻ (mM) solvent diffuses through the 200 (MWCO) Dialysis Membrane. 41) The outcome is jotted down. 42) Both beakers are emptied and cleaned to begin the next trial. 43) Nine millimolar of Albumin is poured into the left beaker. 44) Deionized Water is poured into the right beaker.

The mesh had 144005 elements. The fine meshing is shown in Fig 3. Results: The transient thermal analysis was carried using Ansys Workbench 14.0 and the results were obtained for various time periods. Fig 4 shows the results for Aluminium for all three laser configurations after 60 seconds. Similarly, Fig 5 and Fig 6 show the results for Copper and Stainless Steel respectively.

Repeat steps 2-3 nine more times and record any observations of time change. 5. Now, in the average time section in Table 1, record the calculated average time. 6. Now remove the 3 snap conductors, places an S there and substitute the 100 uf capacitors.

(2004) as follows: The reaction was carried out in 75 mM phosphate buffer (pH 7.4), and the final reaction mixture was 200 µL. Sample (20µL) and fluorescein (120 µL; 70 nM, final concentration) were placed in the well of the microplate. The mixture was pre-incubated for 15 min at 37 °C. AAPH solution (60 µL; 12 mM, final concentration) was added rapidly using a multichannel pipet. The microplate was immediately placed in the reader and the fluorescence recorded every minute for 240 min.

Three alloys were prepared having 2.5, 3.0 and 3.5 weight percent silver designated as hypo-eutectic, eutectic and hyper-eutectic alloys, respectively. To replenish indium losses during alloy making, a 1.5% allowance was added for charge calculations. The alloy making sequence was as follows: first pre-weighed indium shots were placed in an alumina crucible and heated to 165 °C. After complete melting of indium, pre-weighed silver filings were added in the melt and stirred with stainless steel spatula. The temperature of the melt was raised to 185 °C and the melt was kept on stirring for 10 minutes.

After all data was collected, the equation M1V1= M2V2 was used to determine the initial concentrations of each reagent in each run. [Note: The final volume (V2) for each run was 11.0 mL or 0.011 L]. Used the volumes and given molarity concentrations illustrated in Table 1 for M1 and V1. Below, Table 2 shows the finished initial concentrations for each reagent in each of the four

A citrate tube was inoculated with P. aeruginosa and incubated at 37 degrees Celsius at 24 hours. Once the time elapsed the tube was viewed and it changed from its green color to a dark blue color indicating a positive test. Based on these results the next test administrated was the motility test. A inculcating needle containing P. aeruginosa was placed into the motility medium using aseptic technique. The tube was then placed into an incubator at 37 degrees Celsius for 24 hours.

As many as 1 mL hydrogel preparations added in 1 mL of growth medium with stratified so that dilution dilution series made were 50%, 25%, 12.5%, 6.25%, 3.12%, 1.56%, 0.78%, 0.39%, 0.02%, and 0.01% by volume end of the tube was 1 mL. Then as much as 1 mL of bacterial culture equal Mc. Farland 0.5 added into the test tubes so that the final volume of the tubes were 2 mL. All test tubes were incubated at 37 °C for 18 h. Turbidity test observed in the media and determined MIC value preparations. Tube with negative results or does not indicate the presence of growth, then conducted subculture with solid growth media each bacteria as test assertion MIC value chloramphenicol preparations hydrogel.

3.5.2. CONCRETE MANUFACTURE This is a process that describes the making of fresh concrete cubes and testing for compressive strength. The test cubes had a nominal size of 150mm and maximum aggregate size of 20mm. Making test cubes from fresh concrete procedure was in accordance to BS 1881: Part 108: 1983 (cited in Ministry of works, 2000). EQUIPMENT USED • Moulds of cast iron or steel, with removable base plate were prepared.
