Organic reaction mechanisms: An introduction (Breslow, Ronald)

Norman Breslow, an architect of modern biostatistics.

Since the early 1970’s, Norman Breslow has made enormous contributions to statistical theory and its applications in epidemiology, and he was a founding member and principal statistician of the Wilms Tumor Study Group, which is credited with great improvements in the treatment and understanding of this disease. Applications of the biostatistical methods that Norm developed have been concentrate...

Reasoning and Representation: the Sketching of Organic Chemical Reaction Mechanisms

For nearly a century organic chemists have developed a method of sketching chemical reaction mechanisms in order to reason-out the structural transformations that convert one set of molecules into another. Known informally as pushing electrons (or curly arrows), it is a form of chemical illustration in which a sequence of structures is drawn to represent the movement of electrons and nuclei fro...

Ronald Fintushel and Ronald

In order to state our theorems we need to view the Seiberg-Witten invariant of a smooth 4manifold as a multivariable (Laurent) polynomial. To do this, recall that the Seiberg-Witten invariant of a smooth closed oriented 4-manifold X with b2 (X) > 1 is an integer valued function which is defined on the set of spin c structures over X, (cf. [W], [KM],[Ko1],[T1]). In caseH1(X,Z) has no 2-torsion (...

An EPR Study of Heterogeneous Reaction of CH3O2 Radicals with Organic Compounds: Effect of Organic Compound and Surface Nature

The reaction of CH3O2 radicals with acetaldehyde on the solid surface of NH4NO3 has been studied in a flow capillary reactor at low pressure and room temperature. The experiments were performed using EPR spectrometer combined with the kinetic method of radicals freezing. Peroxy radicals revealed an oscillation complex behavior during the process regarding to the phenomenon of radicals multiplic...
