[1] [2] A two milligram dose of fentanyl powder (on pencil tip) is a lethal amount for most people. [3] The United States Centers for Disease Control and Prevention (CDC) has data on drug overdose death rates and totals. Around 1,106,900 US residents died from drug overdoses from 1968 to 2020. Around 932,400 died from 1999 through 2020.

Magnesium (12 Mg) naturally occurs in three stable isotopes: 24 Mg, 25 Mg, and 26 Mg.There are 19 radioisotopes that have been discovered, ranging from 18 Mg to 40 Mg (with the exception of 39
[93] [need quotation to verify] In controlled chamber studies, individuals begin to sense eye irritation at about 0.5 ppm; 5 to 20 percent report eye irritation at 0.5 to 1 ppm; and greater certainty for sensory irritation occurred at 1 ppm and above. While some agencies have used a level as low as 0.1 ppm as a threshold for irritation, the ...
A conductometric titration method can also be used for the determination of the base number of petroleum products. A conductivity sensor is used to measure the conductivity of the analyte which allows the endpoint to be detected. It is suitable for both new and used products having base numbers from 1 mg to 40 mg KOH/g.
In a global assessment, scientists reported, based on medical records, that antibiotic resistance may have contributed to ~4.95 million (3.62–6.57) deaths in 2019, with 1.3 million directly attributed – the latter being more than deaths than from e.g. AIDS or Malaria, [53] [54] despite being project to rise substantially.
The number of protons is called the atomic number of that element. For example, oxygen has an atomic number of 8, meaning each oxygen atom has 8 protons in its nucleus. Atoms of the same element can have different numbers of neutrons in their nuclei, known as isotopes of the element. Two or more atoms can combine to form molecules.
11 is a prime number, and a super-prime. 11 forms a twin prime with 13, [6] and sexy pair with 5 and 17. The first prime exponent that does not yield a Mersenne prime is 11. 11 is part of a pair of Brown numbers. Only three such pairs of numbers are known. [citation needed] Rows in Pascal's triangle can be seen as representation of powers of 11 ...
