We present a study of the results obtained combining LO partonic matrix elements with either LO or NLO partons distributions. These are compared to the best prediction using NLO for both matrix elements and parton distributions. The aim is to determine which parton distributions are most appropriate to use in those cases where only LO matrix elements are available, e.g. as in many Monte Carlo g...

Reductive Claisen rearrangement of 1-allyloxy-8-methoxy-9, 10-anthraquinone followed by demethylation and reduction, and of 1,8-bisallyloxy-9,lO-anthraquinone followed by reduction provides regiospecific syntheses of 2-propyl- and 2,7-dipropyl anthralin

One of the main problems faced in coastal management is loss or destruction beaches due to erosion. A considerable diversity factors involved erosion, which makes it a complex system study. The quality material that constitutes beach, as well choice appropriate materials for its nourishment are two ones. Therefore, make future projects more sustainable and durable, this work proposes sediment c...
