Numerical modeling as a tool for evaluating the renewability of geothermal resources: the case study of the Euganean Geothermal System (NE Italy).

Renewable natural resources are strategic for reducing greenhouse gas emissions and the human footprint. The renewability of these resources is a crucial aspect that should be evaluated in utilization of scenario planning. The renewability of geothermal resources is strictly related to the physical and geological processes that favor water circulation and heating.

The three fetal shunts: A story of wrong eponyms.

The fetal circulatory system bypasses the lungs and liver with three shunts. The foramen ovale allows the transfer of the blood from the right to the left atrium, and the ductus arteriosus permits the transfer of the blood from the pulmonary artery to the aorta. The ductus venosus is the continuation of the umbilical vein, allowing a large part of the oxygenated blood from the placenta to join the supradiaphragmatic inferior vena cava, bypassing the fetal liver and directly connecting the right atrium.

Leonardo Botallo (1530-1587) and his pioneering contributions to traumatology, cardiology and deontology.

Leonardo Botallo (1530-c. 1587) is widely known for the eponymous "foramen Botalli" and "ductus Botalli". The first, most commonly named "foramen ovale", allows blood in the fetal heart to enter the left atrium from the right atrium.
