This paper studies a general notion of flatness in the enriched context: P-flatness where the parameter P stands for a class of presheaves. One obtains a completion of a category A by considering the category F latP(A) of P-flat presheaves over A. This completion is related to the free cocompletion under a class of colimits defined by Kelly. We define a notion of Q-accessible categories for a f...

The fourth party logistics which acts as a new role will increasingly play more and more important functions. In this paper, for a given deformation problems of 4PL providers’ evaluation, We builds up a fourth party logistics evaluating indicator system based on four factors, which are quality, technical abilities, collaboration and price. Besides, we studies the analysis methods of grey correl...

Nonpoint-source pollution of fresh waters by P is a concern because it contributes to accelerated eutrophication. Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods ...
