Modelling and Simulation of an Electric Motor-Generator Set for Internal Combustion Engine Replacement

open access: yesApplications of Modelling and Simulation, 2021
In this paper, a squirrel cage induction motor was used as the prime mover of a permanent magnet synchronous electric generator to achieve a motor-generator set purposed for internal combustion (IC) engine replacement.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Application of optimization algorithms in the design of a superconducting A.C. generator rotor [PDF]

open access: yes, 1990
The superconducting a.c. generator is expected to be the optimum choice among a.c. generation systems in future because of its reduced size, high efficiency, high terminal voltage and its contribution to the stability of the power system.

Modelling and control of a variable-speed switched reluctance generator based wind turbine

open access: yes, 2007
This paper studies the system modelling and control aspects of switched reluctance generator (SRG) based variable speed wind turbines. A control system is implemented to provide proper operation of the SRG as well as power tracking capabilities for ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Variable speed of the wind turbine generator with DFIG connected to electric grid

open access: yesRevue des Énergies Renouvelables, 2008
The variable speed wind turbine generator with doubly-fed induction generator (DFIG) is today widely used concept. This paper presents a control system of the doubly-fed induction generator wind turbine with focus on the control strategies and on active ...

PERMANENT-MAGNET INDUCTION GENERATORS: AN OVERVIEW [PDF]

open access: yesJournal of Engineering Science and Technology, 2011
The advantage of using a permanent-magnet induction generator (PMIG) instead of a conventional induction generator is its ability to suppress inrush current during system linking when synchronous input is performed.

Autonomous mode and parallel operation of an asynchronous generator with the electrical network [PDF]

open access: yesE3S Web of Conferences
This article explains that an asynchronous machine, like other electrical machines, can operate as a motor and generator due to the property of reciprocating motion and that an asynchronous generator is not different in design from an induction motor ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
