As drilling of new oil and gas wells increase to meet energy demands, it is essential to optimize processes to ensure the health and safety of the crew as well as the protection of the environment.Drilling operations represent a dynamic and challenging environment with natural and mechanical factors that need to be closely managed.Well control refe
Biogeographic Patterns in Members of Globally Distributed and Dominant Taxa Found in Port Microbial Communities
ABSTRACT We conducted a global characterization of the microbial communities of shipping ports to serve as a novel system to investigate microbial biogeography.The community structures of port microbes from marine and freshwater habitats house relatively similar phyla, despite spanning large spatial scales.As part of this project, we collected 1,21
Mechanisms of Floor Heave in Roadways Adjacent to a Goaf Caused by the Fracturing of a Competent Roof and Controlling Technology
In traditional sequential single-wing mining practices, one-entry longwall mining systems make it challenging to efficiently and smoothly transfer mining equipment during a continuous mining sequence.In two-entry longwall virginia mill works tobacco road acacia systems, the headgate of the current panel and the tailgate of the next panel are excava
