The Solar Component of the Atmospheric 14C Recordar intervals while similar fluctuations that last only ca. 200 years (“Maunder types”) are found 9 times. The decadal and bi-decadal records of atmospheric Δ.C and model-derived .C production rates, with long-term trend removed, are displayed in 1000 yr intervals.

Variability of the Present and Ancient Sun: A Test of Solar Uniformitarianismcords. For this purpose we consider naked-eye observations of the Sun, records of the aurora, the tree-ring record of .C, initial investigations of ice-borne .Be, and the possible records of solar influence that are found in sedimentary deposits from the Precambrian.

Model Comparison of 14C and 10Be Isotope Records past variations of the geomagnetic field. For .C, the possibility must be considered that the mean production rate before the start of the tree-ring record was higher than in the past 9000 years and that the observed long-term .C decrease is thus due to radioactive decay of the “excess” produced in the past.

M. R. Attolini,M. Galli,T. Nannimodes. A PASA hand is developed with three PASA fingers and 8 degrees of freedom (DOFs). Each finger in the PASA hand has two joints, mainly consists of an actuator, an accelerative gear system, a spring, a parallel four-link mechanism and a mechanical limit. Two extra actuators in the palm of the P
