Assessing phytase activity–methods, definitions and pitfalls. [PDF]

open access: yes, 2015
Phytases are nutritionally important for increased bioavailability of dietary minerals and phosphate for monogastric animals including humans. Release of minerals and phosphate is accomplished by the enzymatic stepwise degradation of phytate (inositol ...

Spectral function of the Bloch-Nordsieck model at finite temperature [PDF]

open access: yes, 2013
In this paper we determine the exact fermionic spectral function of the Bloch-Nordsieck model at finite temperature. Analytic results are presented for some special parameters; for other values we have numerical results.

Solution of a system of ordinary differential equations on a computer by the Nordsieck method

open access: yes, 1962
A reliable efficient general-purpose method for automatic digital computer integration of systems of ordinary differential equations is described. The method operates with the current values of the higher derivatives of a polynomial approximating the ...

A counter-example to the Bloch-Nordsieck theorem in quantum chromodynamics.

open access: yes, 2012
Usando teoria de perturbação, fizemos uma análise detalhada da divergência infravermelha em 4ª ordem do processo de aniquilação do par elétron-pósitron. Mostramos que o teorema de Bloch-Nordsieck garante o cancelamento destas divergências em QED.
