In construction project, which is highly dynamic and complex, risk factors affect the expected achievement rates three main performance goals, namely schedule, cost, quality. A comprehensive management procedure requires crucial steps: confirmation, analysis, treatment. Risk analysis core management. Through structural equation modeling, this s...

Today, the number of scientific research projects in universities is increasing. The content and system will be more and more complex. The technology in projects will be advanced. And the cost will increase too. The project management involves various factors. More and more uncertain factors will increase the project risk of demonstrating and studying. At present, we still lack the valid means ...

AIMS The aim of the study was to determine the influence of endothelial progenitor cells (EPC) on erectile dysfunction (ED).
