We show that to n loop order the divergent content of a Feynman amplitude is
spanned by a set of basic (logarithmically divergent) integrals which need not
be evaluated. Only the coefficients of the basic divergent integrals are
necessary to determine renormalization group functions. Relations between these
coefficients of different loop orders are derived.Comment: 10 pages, 5 figure
We present a both ultraviolet and infrared regularization independent
analysis in a symmetry preserving framework for the N=1 Super Yang-Mills beta
function to two loop order. We show explicitly that off-shell infrared
divergences as well as the overall two loop ultraviolet divergence cancel out
whilst the beta function receives contributions of infrared modes.Comment: 7 pages, 2 figures, typos correcte
Trinta tourinhos ¾ Canchim + ¼ Nelore com 15 meses de idade e peso corporal médio de 417 kg foram confinados durante 84 dias. Os animais foram alimentados com rações compostas por silagem de milho, milho, farelo de algodão, farelo de soja, soja integral e mistural mineral, ajustadas segundo as recomendações do Sistema de Proteína Metabolizável (MP), do Sistema de Proteína e Carboidratos Líquidos de Cornell (CNCPS) e do Sistema de Proteína Digestível no Intestino (PDI), para ganho de peso corporal previsto de 1,3 kg/cab/dia. O ganho diário de peso corporal não diferiu entre os tratamentos CNCPS, MP e PDI, com médias de 1,48; 1,51; e 1,13 kg/cab, respectivamente.
