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

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

Part 1. Hydrocarbon Nomenclature From International Union of Pure and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right

Organic Farming versus Conventional Farming With the increase in concern about the dangers of the foods we consume‚ the demand for organic food has increased at an alarming rate. Conventional farming has been around for more than 100 centuries‚ and it is one of the most prosperous industries in the world. Organic farming on the other hand dates back to the 20th century. Sir Albert Howard is considered by many to be the pioneer of the organic movement (Heckman). Although some concepts of organic
