The stability of grid-connected wind power system (GCWPS) is prone to deteriorate due to the impedance interaction between wind turbines and the weak grid.For purpose of finding out the cause of power oscillation and effectively improving the stability of GCWPS under weak grid, firstly of all, a frequency coupling impedance model (FCIM) click here

The classical Poisson-Boltzmann model can only work when ion concentrations are very dilute, which often does not match the experimental conditions.Researchers have been working on the modification of the model to include the steric effect of ions, which is non-negligible when the ion concentrations are not dilute.Generally the steric effect was mo

The incorporation of sex and gender variables in medical education can be made more intuitive and accurate with thoughtful intervention.The authors propose a flowchart to make medical education veuve ambal rose tools more precise and applicable to patients who would benefit from a nuanced approach to sex and gender.The Body Guidelines can here empo

Using some of the evidence collected as part of a doctoral study of school-based leaders of art in the UK, this paper presents the most recent and emergent models of the leadership in art.The data suggests likely attributes of those in leadership positions and the effects upon the activities in which those individuals engage.As a case read more stu

MHC class II (MHC-II) molecules are present on antigen presenting cells (APCs) and these molecules function by binding here antigenic peptides and presenting these peptides to antigen-specific CD4+ T cells.APCs continuously generate and degrade MHC-II molecules, and ubiquitination of MHC-II has recently been shown to be a key regulator of MHC-II ex
