Kinetic-spectrophotometric method for the determination of trace amounts of bromide in seawater [PDF]
, 2005 A novel simple, sensitive and rapid kinetic-spectrophotornetric method is proposed for the determination of trace amounts of bromide. The method is based on its catalytic effect on the oxidation of methylene blue (MB) by hydrogen peroxide in strongly ...

An Exploration of the Permanent-Determinant Method [PDF]
The Electronic Journal of Combinatorics, 1998 The permanent-determinant method and its generalization, the Hafnian-Pfaffian method, are methods to enumerate perfect matchings of plane graphs that were discovered by P. W. Kasteleyn. We present several new techniques and arguments related to the permanent-determinant with consequences in enumerative combinatorics. Here are some of the results that

A Method for the Determination of Trinitrotoluene in Air [PDF]
Occupational and Environmental Medicine, 1958 Properties of Trinitrotoluene Trinitrotoluene is the high explosive used as a main bursting charge in shells, mines, and bombs. It is a potent poison for the liver, blood, and blood-forming organs, and fatalities have been recorded from toxic anaemia, toxic jaundice, and acute yellow atrophy of the liver. From 1916 to 1918 there were notified 403 cases
