Petiole may also be used in the context of wing veins,
National Fund for Scientific Research Auguste Piccard. The FNRS-1 was a balloon that set a world altitude record. The NFSR also funded the FNRS-2, which was the first ever bathyscaphe built. National Fund for Scientific Research The National Fund for Scientific Research (NFSR) (Dutch: NFWO, French: FNRS) was once a government institution in Belgium for supporting scientific research until it was split into two separate organizations: and The task of the FWO and F.R.S.–FNRS is to stimulate the development of new knowledge in all scientific disciplines. The means to achieve this, is to finance excellent scientists and research projects after an inter-University competition and with
