I give a simple general prescription for computing the spectral functions of local operators in the Tomonaga-Luttinger model from the space-time correlation functions. The method is significantly simpler than directly transforming the space-time Greens function and allows a physical interpretation of the singularities encountered in the spectral function. 71.20.-b, 71.27.+a, 79.60.-i Typeset us...

Many greenkeepers and authorities are concerned about the environmental risks resulting from pesticide use on golf courses. We studied leaching surface runoff of fungicides metabolites for two winter seasons after fall application boscalid, pyraclostrobin, prothioconazole, trifloxystrobin, fludioxonil in field lysimeters at NIBIO Landvik, Norway. The applications were made creeping bentgrass gr...
