Tuskegee Syphilis experiment is the most infamous clinical study conducted in the United States between 1932 -1972. The study of natural progression of untreated syphilis in rural Africa American men‚ led to a forty year study which was controversial for reasons related to ethical standards; researchers knowingly failed to treat patients after the 1940s validation of penicillin. The patients with syphilis were never told they had it‚ were part of a case study‚ could leave the experiment at any given

If one goes out before we wake up‚ we will get two more of the same type of battery and watch it during the day. Variables Our variable is the different brand of batteries. The controlled condition is the same type of flashlights. Results Our experiment showed that Rayovac outlasted all of the other batteries we tested by at more than two hours. The Eveready battery‚ which is a regular‚ non-alkaline battery‚ lasted only 6 hours and 35 minutes. The Duracell lasted 15 hours. The Energizer lasted

the balls will also increase. This is because the increasing drop height will result in an increase in the gravitational potential energy found within the balls that results in an increased transformation into kinetic will transform back into kinetic energy on the rebound; the by-product of which is a greater bounce height. The hypothesis was supported by the results. The results showed a clear trend where a steady increase of the drop height resulted in a rise in the bounce height of the ball. The

scorching afternoon on the soccer fields. The parched grass begs for even the most miniscule drop of water. Sweat streams down my face as my cleats claw their way forward at top speed. My lungs spasm with gasps‚ desperate to get enough oxygen. A soccer ball soars gracefully through the air and lands perfectly at my tired feet. It takes me a millisecond to realize what has happened but I quickly snap to attention as a teammate yells out. My legs move instinctively towards their destination—the net. A player

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

HER FIRST BALL KATHERINE MANSFIELD EXACTLY when the ball began Leila would have found it hard to say. Perhaps her first real partner was the cab. It did not matter that she shared the cab with the Sheridan girls and their brother. She sat back in her own little corner of it‚ and the bolster on which her hand rested felt like the sleeve of an unknown young man’s dress suit; and away they bowled‚ past waltzing lamp-posts and houses and fences and trees.
