power on weld bead geometry and performance parameters such as duty cycle‚ pulse overlap‚ energy density and bead diameter. In this contest‚ first experiment is conducted on austenitic 304L stainless steel sheet by varying the welding speed from 2 mm/s to10 mm/s and second experiment is conducted varying laser power from 300 W to 3500 W. It was found from the experimental and analytical approach welding speed and laser power significantly affects on weld bead geometry‚ variation in bead diameter

will model the effects of mutations on the genetic code. Some mutations cause no structural or functional change to proteins while others can have devastating affects on an organism. Materials Red Beads Blue Beads Yellow Beads Green Beads Procedure: 1. Using the red‚ blue‚ yellow and green beads‚ devise and lay out a three color code for each of the following letters (codon). For example Z = green : red : green. In the spaces below the letter‚ record your “code”. C: E: H: I: K: L: red green

Department College of Science and computer Sciences‚ De La Salle University-Dasmarinas ABSTRACT: The central dogma of biology holds that genetic information normally flows from DNA to RNA to protein. In the experiment‚ DNA and RNA bead kits were used. Different coloured beads correspond to different nitrogenous bases‚ sugars and phosphates. Different structures of DNA and RNA were formed based on the sequences that were given. INTRODUCTION: DNA contains the complete genetic information that defines

The hypothesis of this experiment is that the materials can be separated back into their original forms with the same masses. * Materials: - 3.0 grams of salt(NaCl) -3.0 grams of sand‚ -3.5 grams of beads‚ - 2.0 grams of sawdust‚ - 300mL of water (H20)‚ - Beakers -a funnel -scale -a hot plate -dishes -tweezers * Procedure:

She gathered a selection of small beads of blues‚ purples‚ pinks and yellows and announced that she was going to make a beautiful necklace. | | She held the string in her left hand and a bead in her right hand. Using her thumb and first two fingers she pushed each bead onto the fine plastic string. | Isabella’s fine motor skills allow her to thread beads onto a string. | When the hole of a bead appeared too small for the string

Columbus used words such as “Beautiful Trinkets”(2) “Keenest Wit”(2) and “Extremely Fruitful fields”(2). Where he is saying “Beautiful Trinkets” he talks about what the sailors have including but not limited to the homemade things they have made or some of the items they found out on their journeys.
