Use of the DFE reflects the higher bioavailability of synthetic folic acid found in supplements and fortified food compared to that of naturally occurring food folates (18). 1  1 microgram (Î¼g) of food folate provides 1 Î¼g of DFEs. 2  1 Î¼g of folic acid taken with meals or as fortified food provides 1.7 Î¼g of DFEs.
The Four Seasons (Complete)Vivaldi cast The Four Seasons in the form of four concertos for solo violin and string orchestra. Concertos are designed to feature an instrument which not only enjoys an especially prominent role but plays technically brilliant, or virtuosic, passages.
There are five main woodwind instruments: flute, oboe, clarinet, saxophone, and bassoon. Each of these instruments also come in different versions: The flute has a small version called the piccolo which plays an octave higher. It is the highest instrument in the orchestra. Occasionally there is an alto flute which is longer and plays a fifth (half an octave) lower than the flute. Most woodwind instruments need a reed, but the flute does not have a reed.
