  2. Atomic absorption spectroscopy - Wikipedia

    Its sensitivity is 2–3 orders of magnitude higher than that of flame AAS, so that determinations in the low μg L −1 range (for a typical sample volume of 20 μL) and ng g −1 range (for a typical sample mass of 1 mg) can be carried out. It shows a very high degree of freedom from interferences, so that ET AAS might be considered the most ...

    For the spherical case, one can first compute the length of side from the point at α to the ship (i.e. the side opposite to β) via the ASA formula ⁡ = ⁡ ⁡ ⁡ (+) + ⁡ ⁡ (), and insert this into the AAS formula for the right subtriangle that contains the angle α and the sides b and d: ⁡ = ⁡ ⁡ = ⁡ + ⁡ ⁡. (The planar ...

    en.wikipedia.org/wiki/Congruence_(geometry)

    AAS (angle-angle-side): If two pairs of angles of two triangles are equal in measurement, and a pair of corresponding non-included sides are equal in length, then the triangles are congruent. AAS is equivalent to an ASA condition, by the fact that if any two angles are given, so is the third angle, since their sum should be 180°.

  5. Degree-of-difference - Wikipedia

    Degree of Difference Testing, which is also known as DOD is a method to determine an overall difference among test and control groups when product in question has exhibited variability that would have caused because of multiple factors such as the production time, use of multiple components, preparation or others.

    the sum of degrees is even so that is an integer the triangular condition is satisfied m + n ≥ l ≥ m − n {\displaystyle m+n\geq l\geq m-n} Dong and Lemus (2002) [ 4 ] generalized the derivation of this formula to integrals over a product of an arbitrary number of associated Legendre polynomials.
