Paracetamol, [a] or acetaminophen, [b] is a non-opioid analgesic and antipyretic agent used to treat fever and mild to moderate pain. [13] [14] [15] It is a widely available over-the-counter drug sold under various brand names, including Tylenol and Panadol.
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell.The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass.
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]

[2] [3] [4] The pathway is a minor pathway in GABA synthesis compared to the main pathway in which GABA is synthesized from glutamate. [ 2 ] [ 3 ] [ 4 ] However, the pathway has been found to have an important physiological role in the brain, for instance in the production of GABA in the striatum and resultant inhibition of dopaminergic neurons ...
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.

The relative static permittivity of a solvent is a relative measure of its chemical polarity. For example, water is very polar, and has a relative static permittivity of 80.10 at 20 °C while n - hexane is non-polar, and has a relative static permittivity of 1.89 at 20 °C. [ 26 ]
