Many bacteria like Bacillus subtilis can produce such an enzyme to help scientists identify unknown bacterial samples -- the starch-iodine test is one of many tests needed to identify the exact bacterium. [13] The positive test for bacteria that has starch hydrolysis capabilities (able to produce amylase) is the presence of a yellow zone around ...
The Turing test, originally called the imitation game by Alan Turing in 1949, [2] is a test of a machine's ability to exhibit intelligent behaviour equivalent to that of a human. In the test, a human evaluator judges a text transcript of a natural-language conversation between a human and a machine. The evaluator tries to identify the machine ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...

Mann was an American medical researcher, physician, academic, and author known for his research on cholesterol's impact on cardiovascular health.He served as an assistant professor at Harvard University early in his career and as a professor and researcher of medicine and biochemistry at Vanderbilt University until his retirement.
In many laboratory experiments it is good practice to have several replicate samples for the test being performed and have both a positive control and a negative control. The results from replicate samples can often be averaged, or if one of the replicates is obviously inconsistent with the results from the other samples, it can be discarded as ...

The Bruce protocol is a standardized diagnostic test used in the evaluation of cardiac function and physical fitness, developed by American cardiologist Robert A. Bruce. [1] According to the original Bruce protocol the patient walks on an uphill treadmill in a graded exercise test with electrodes on the chest to monitor.
