The K project nuclear testing series were all high altitude tests fired by missiles from the Kapustin Yar launch site in Russia across central Kazakhstan toward the Sary Shagan test range (see map below). Two of the tests were 1.2 kiloton warheads tested in 1961. The remaining three tests were of 300 kiloton warheads in 1962.
The test was developed by Otto Prausnitz and Heinz Küstner. [1] The first PK test occurred in 1921 when Prausnitz injected Küstner's serum into his abdominal skin. [2] [3] Küstner had previously noted that he developed allergic symptoms after eating fish. After eating some fish, Prausnitz's skin became hot, red, and swollen at the site of ...
In statistics, D'Agostino's K 2 test, named for Ralph D'Agostino, is a goodness-of-fit measure of departure from normality, that is the test aims to gauge the compatibility of given data with the null hypothesis that the data is a realization of independent, identically distributed Gaussian random variables.
The reagent for the K test is an aqueous solution of potassium hydroxide (KOH) (10–25%), or, in the absence of KOH, a 10% aqueous solution of sodium hydroxide (NaOH, lye), which provides nearly identical results. [4]
The test is performed by loading steadily at a rate such that K I increases from 0.55 to 2.75 (MPa)/s. During the test, the load and the crack mouth opening displacement (CMOD) is recorded and the test is continued till the maximum load is reached. The critical load P Q is calculated through from the load vs CMOD plot.
In dialysis, sorbents like ferric oxide hydroxide and activated carbon can be used to remove toxins and positively charged ions from dialysate, thus reducing the amount of water needed for a ...
A parent whose daughter plays high school basketball recently reached out to me. This person had revisited my October 2023 article on the troubling conduct of parents at youth and high school ...
The test can be used for coatings or for base materials. The test method is defined by various standards, DIN EN ISO 6988, [2] DIN 50018, [3] ASTM G87, ISO 3231, ISO 22479 are the most common. The parts to be tested are placed in a test chamber with a capacity of 300L and exposed to warm, moist air in combination with a certain amount of sulfur ...
