Pro Experimental Surgery. Experimental surgery‚ is a taboo subject. Many oppose it‚ many do not. Doctors perform surgery on someone in an effort to make them feel better or learn a little more about their condition. When scientists and doctors try new things they usually try them on animals‚ studying the results‚ heightening their techniques‚ and exploring new ways to heal people. But sometimes doctors are put on the spot‚ so they have to take action or someone will be seriously hurt. Experimental

effect of a new “miracle” drug that can temporarily inactivate areas of the brain is an experimental study. An experimental study is a controlled experiment in which the researcher has control over one variable‚ called the independent variable. The researcher then manipulates the independent variable and studies how that affects the variable he is measuring‚ called the dependent variable. Because this experiment includes the study of how the independent variable‚ in this case the “miracle” drug‚ affects

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

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

Tuskegee syphilis experiment was an 40 year clinical study conducted by the U.S. Public Health Service to analyze the natural progression of untreated syphilis in African American men. The purpose of the study was to record the natural history of syphilis in African Americans. Beginning in 1932‚ researchers enrolled 399 males who had previously contracted syphilis before the study began and 201 who didn’t carry the disease. The study took place in Macon County‚ Alabama.
