ANALYSIS OF THE IMPACT OF TRANSIENT OVERVOLTAGE ON GRID-CONNECTED PMSG-BASED WIND TURBINE SYSTEMS


POLISH FARM MACHINERY MARKET AFTER ACCESSION TO THE EUROPEAN UNION – PRICES OF MEANS OF AGRICULTURAL MECHANIZATION

VAT for farm machinery has been increased from 0 to 22% level since the accession to the EU.This was a main reason for rise in prices of a set of 34 farm machines which in June 2004 was by 28.1% higher than a year earlier.Thanks to the decrease in prices of the most expensive farm machines – harvester threshers, during the years 2006--2009 th

Feasibility of free-breathing quantitative myocardial perfusion using multi-echo Dixon magnetic resonance imaging

Abstract Dynamic contrast-enhanced quantitative first-pass perfusion using magnetic resonance imaging enables non-invasive objective assessment of myocardial ischemia without ionizing radiation.However, quantification of perfusion is challenging due to the non-linearity between the magnetic resonance signal intensity and contrast agent concentratio
