Titrator, Review II (Dice, David D.)

Design of an automatic titrator

By David D . Awschalom , Ryan Epstein

Oc tober 20 07 Diamond has a track record of extremes, including ultrahardness, higher thermal conductivity than any other solid material and transparency to ultraviolet light. In addition, diamond has recently become much more attractive for solid-state electronics, with the development of techniques to grow high-purity, singlecrystal synthetic diamonds and insert suitable impurities into them...

Immunoglobulin (Ig) molecules consist of two identical heavy (H) polypeptide chains and two identical light (L) polypeptide chains held together by noncovalent forces and disulfide bonds (1). The structural genes encoding these chains are grouped into at least three sets, one encoding H chains, one encoding L chains of the x class, and one encoding L chains of the h class (2). Three subclasses ...

A computer-controlled potentiometric/spectrophotometric titrator

A laboratory computer controlled potentiometric titrator interfaced to a diode array spectrophotometer is described. The titrator consists of widely used, commercially available components; therefore, major attention is given to modes of interconnection and software implementation in data format and system control. Replicate potentiometric titrations of glycines gave a relative standard deviati...

Tied dice

A generalized die is a list (x1; :::; xn) of integers. For integers n 1, a b and s let D(n; a; b; s) be the set of all dice with a x1 ::: xn b and P xi = s. Two dice X and Y are tied if the number of pairs (i; j) with xi < yj equals the number of pairs (i; j) with xi > yj . We prove the following: with one exception (unique up to isomorphism), if X 6= Y 2 D(n; a; b; s) are tied dice neither of ...
