Prostate specific antigen (PSA) 40–49 years: 1.2–2.9 [75] μg/L [5] [15] or ng/mL [23] More detailed cutoffs in PSA – Serum levels: 70–79 years, non-African-American: 4.0–9.0 [75] 70–79 years, African-American: 7.7–13 [75] PAP: 3 [23] units/dL (Bodansky units) Calcitonin: 5, [76] 15 [76] ng/L or pg/mL: Cutoff against medullary ...
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
Most countries forbid operation of motor vehicles and heavy machinery above prescribed levels of blood alcohol content. Operation of boats and aircraft is also regulated. Some jurisdictions also regulate bicycling under the influence. The alcohol level at which a person is considered legally impaired to drive varies by country.
If a right-tailed test is considered, which would be the case if one is actually interested in the possibility that the coin is biased towards falling heads, then the p-value of this result is the chance of a fair coin landing on heads at least 14 times out of 20 flips.
Aminoalkylindoles are considered to be the most common synthetic cannabinoids found in synthetic cannabinoid blends, likely due to the fact that these molecules are easier to synthesize than classical and non-classical cannabinoids. The JWH molecules were first synthesized by John William Huffman at Clemson University in the late 1990s. [92]
The AB magnitude zero point is defined such that an object's AB and Vega-based magnitudes will be approximately equal in the V filter band. However, the AB magnitude system is defined assuming an idealized detector measuring only one wavelength of light, while real detectors accept energy from a range of wavelengths.
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. [1]
The Philippines, [f] officially the Republic of the Philippines, [g] is an archipelagic country in Southeast Asia.In the western Pacific Ocean, it consists of 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao.
