element tensile test is conducted for element size of 5mm at strain rates mentioned in Fig. 7 7. The true stress versus plastic strain results of the simulation in comparison to the load curve is shown in Fig. 7 9. As the damage is coupled to the stress tensor by Eq. 4 1‚ there is a continuous reduction of stress. The plastic strain at failure for different strain rates is shown in Fig. 7 11 which is in accordance to the scaling factor given for different strain rates. One element tensile test is also conducted

The Urea test was used to test both Unknown Gram-positive and Unknown Gram-negative bacteria. One colony of bacteria was used from the Unknown 13A plate and Unknown 13B plate in order to inoculate the Urea Slant. After the slant was inoculated‚ the cultures were placed in an incubator at 35ºC for Gram-positive bacteria‚ and 37ºC for Gram-negative bacteria for a total of 48 hours. If the Urea test were positive‚ the color of the slant would have changed to a hot pink color‚ which indicated the bacteria’s

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a
