Flow-through polarographic cell for flow-injection analysis. Determination of nifedipine in pharmaceutical formulations
(JOHN WILEY & SONS INC, 1997)
A simple design of a polarographic flow-through cell is proposed in which a conventional dropping mercury electrode (DME) is used as working electrode, and a mercury pool and a platinum wire are used as the reference and ...
Substitution-newton-Raphson method for the solution of electric network equations
(2006-12-01)
The power flow problem, in transmission networks, has been well solved, for most cases, using Newton-Raphson method (NR) and its decoupled versions. Generally speaking, the solution of a non-linear system of equations ...
Obtaining flow curve for viscoplastic fluids through inclined open-channel apparatus
(Springer, 2021-05-01)
Non-Newtonian fluids are commonly seen in industrial processes, such as those of the oil and mining industry, and in natural flows, like dam ruptures, landslides or mud flows. The hydrodynamic modeling of such processes/phenomena ...
Robust control applied to power flow control in single-phase inverter with LCL filter, using droop control and D-stability
(2012-12-01)
This paper proposes a new methodology to control the power flow between a distributed generator (DG) and the electrical power distribution grid. It is used the droop voltage control to manage the active and reactive power. ...
Flow injection method for preconcentration and polarographic determination of copper in water
(WILEY-V C H VERLAG GMBH, 2000-03)
The analytical application of a simple polarographic Row through cell, which was previously designed for the continuous polarographic analysis of organic compounds in pharmaceuticals and urine, is proposed in this work for ...
Influence of modeling in load flow analysis of three phase distribution systems
(IEEE, 1990)
The authors present a comparison of three phase load flow algorithms for distribution power systems. Reference is made to traditional single-phase load flow methods used in transmission systems and the main three-phase ...
Practical and theoretical consideration of flow-through microcalorimetry: determination of 'thermal volume' and its flow rate dependence
(Elsevier Science BvAmsterdamHolanda, 2004)
Comparison between PEF values obtained from a population sample in the city of Sao Carlos, Brazil, and reference values
(Soc Brasileira Pneumologia TisiologiaBrasilia DfBrasil, 2009)
