The Indiana pi bill was bill 246 of the 1897 sitting of the Indiana General Assembly, one of the most notorious attempts to establish mathematical truth by legislative fiat. Despite its name, the main result claimed by the bill is a method to square the circle .
(E 2, E 3) and (E 4, E 5) are degenerate E 2 = α + β: HOMO E 3 = α + β: HOMO E 4 = α − β: LUMO E 5 = α − β: LUMO E 6 = α − 2β: Table 1. Hückel method results. Because α and β are negative, [8] orbitals are in order of increasing energy. HOMO/LUMO/SOMO = Highest occupied/lowest unoccupied/singly-occupied molecular orbitals.
The F I O 2 is used in the APACHE II (Acute Physiology and Chronic Health Evaluation II) severity of disease classification system for intensive care unit patients. [4] For F I O 2 values equal to or greater than 0.5, the alveolar–arterial gradient value should be used in the APACHE II score calculation. Otherwise, the PaO 2 will suffice. [4]
The atmospheric pressure is roughly equal to the sum of partial pressures of constituent gases – oxygen, nitrogen, argon, water vapor, carbon dioxide, etc.. In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas as if it alone occupied the entire volume of the original mixture at the same temperature.

That is 8 times , the volume of each particle of radius /, but there are 2 particles which gives 4 times the volume per particle. The total excluded volume is then =; that is, 4 times the volume of all the particles. Van der Waals and his contemporaries used an alternative, but equivalent, analysis based on the mean free path between molecular ...
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
∆ may refer to: . Triangle (∆), one of the basic shapes in geometry. Many different mathematical equations include the use of the triangle.; Delta (letter) (Δ), a Greek letter also used in mathematics and computer science
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
