List of political self-immolations. The self-immolation of Thích Quảng Đức, done in protest against Buddhist persecution by Christians. This is a list of notable people who committed self-immolation, the act of setting themselves on fire for political reasons. Non-political self-immolations are not included in the list.
By definition, pOH is the negative logarithm (to the base 10) of the hydroxide ion concentration (mol/L). pOH values can be derived from pH measurements and vice-versa. The concentration of hydroxide ions in water is related to the concentration of hydrogen ions by. where KW is the self-ionization constant of water.
Poh Yuan Nie (born 21 December 1965; 傅媛聂 Fù Yuánnìe), alias Pony Poh or Owen Fu, is a Singaporean fugitive listed on Interpol's international Red Notice list. Poh, the former principal of a tuition centre in Singapore, was charged and convicted of masterminding and abetting several students to cheat in their O-level examinations in 2016.
Po-Shen Loh (Chinese: 罗博深; born June 18, 1982) is an American mathematician specializing in combinatorics. Loh teaches at Carnegie Mellon University, and from 2014 to 2023 served as the national coach of the United States' International Mathematical Olympiad team. He is the founder of educational websites Expii and Live, and lead ...
With pOH obtained from the pOH formula given above, the pH of the base can then be calculated from =, where pK w = 14.00. A weak base persists in chemical equilibrium in much the same way as a weak acid does, with a base dissociation constant (K b) indicating the strength of the base. For example, when ammonia is put in water, the following ...
Podiatry (/ poʊˈdaɪ.ətri / poh-DY-ə-tree), or podiatric medicine and surgery (/ ˌpoʊdiˈætrɪk, poʊˈdaɪ.ətrɪk / POH-dee-AT-rik, poh-DY-ə-trik), is a branch of medicine devoted to the study, diagnosis, and treatment of disorders of the foot, ankle and lower limb. The healthcare professional is known as a podiatrist. [1]
An at-risk student is a term used in the United States to describe a student who requires temporary or ongoing intervention in order to succeed academically. [1] At risk students, sometimes referred to as at-risk youth or at-promise youth, [2] are also adolescents who are less likely to transition successfully into adulthood and achieve economic self-sufficiency.

A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1] Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the ...
