Abstract Electrical submersible pumps (ESPs) are a well-known artificial lift technology used in the oil and gas industry to enhance production. One of major requirements implement ESPs is need for rig install or replace failed frequently. Temporary rigless (TRL ESPs) new that being developed tested many parts world. The main advantage this its much lower installation cost compared conventional...

Phase III development of a micro-hydroelectric power generating system is focused on enhancing the system designed by Phases I and II. The previous phases focused on the use of the Gorlov Helical Turbine (GHT) to derive power from a fresh water environment, specifically the Stevens River in Vermont. Phase III exclusively focused on deriving power from an ocean environment and the construction o...

In the last few decades, several monitoring systems integrated with water level detection have been major research focus. Production boost and its sustainability depend mainly on sustainable supply, measuring level, avoiding waste of is an essential task for all stakeholders. Therefore, aim this paper to design implement a mobile phone-based remote control. This will be applied control operatio...

Current hemodynamic dogma suggests that the increase in central blood pressure during exercise is largely driven by augmentation of pressure from wave reflections. However, this hemodynamic presupposition lacks teleological and physiological support. During dynamic aerobic exercise, there are marked reductions in terminal impedance because of peripheral metabolic vasodilation. Moreover, despite...

The enterococcal surface protein Esp, specifically linked to nosocomial Enterococcus faecium, is involved in biofilm formation. To assess the role of Esp in endocarditis, a biofilm-associated infection, an Esp-expressing E. faecium strain (E1162) or its Esp-deficient mutant (E1162Δesp) were inoculated through a catheter into the left ventricle of rats. After 24 h, less E1162Δesp than E1162 were...

We derive macroscopic equations of motion for the slowly varying electric field amplitude in three-dimensional active nonlinear optical nanostructures. We show that the microscopic Maxwell equations and polarization dynamics can be simplified to a macroscopic one-dimensional problem in the direction of group velocity. For a three-level active material, we derive the steady-state equations for n...
