Chemical Considerations in the Accelerator Production of N-13: N-13-Nitrosourea Preparation

IEEE Transactions on Nuclear Science, 1979
The preparation of N-13-nitrosoureas from N-13 produced by a Van de Graaff accelerator and a cyclotron are described. Consideration is given to the characteristics of the accelerator which can affect the chemical form of the isotope produced. When the isotope is to be used in chemical synthesis, its initial chemical form dictates the chemical ...

On Shapiro's Cyclic Inequality for N = 13

Mathematics of Computation, 1985
\textit{H. S. Shapiro} [Am. Math. Mon. 61, 571 (1954)] raised the problem to prove that for every integer \(n\geq 3\) \[ \sum^{n}_{i=1}x_ i/(x_{i+1}+x_{i+2})\geq n/2, \] where \(x_{n+1}=x_ 1\), \(x_{n+2}=x_ 2\), for all non-negative \(x_ i\) such that \(x_ i+x_{i+1}>0.\) As it is proved by various authors this inequality holds for \(n\leq 12\) and does

Le terme d’entremetteur peut sembler pejoratif.
