The earth sciences in the scientific letters of Giovanni Capellini
No full textGiovanni Capellini (1833-1922) was one of the leading representatives of the Italian and international scientific community from the mid-19th century until 1922, the year of his death.
Professor of Geology at the University of Bologna from 1860, geologist, palaeontologist and archaeologist, in 1871 he organised, straight after the unification of Italy, the 5th International Congress in Archaeology and Prehistoric Anthropology, first in Italy, and in 1881 brought to Bologna, for the first time ever in Italy, the 2nd International Geological Congress. His studies and publications strongly influenced the geological thinking of his times.
At the Archiginnasio Library in Bologna there are as many as 30,000 documents from his scientific letters (The Capellini Archive), the result of an intense correspondence he had with geologists, seismologists, astronomers and meteorologists, but also with people from the world of culture and politics. The letters relating to the earth sciences, from scientific but also political point of view, are the majority. The archive includes letters from more then 4,300 senders, of which at least 25% foreign ones incuding Charles Lyell (geologist), Emmanuel Friedlaender (volcanologist), Philip Eduard De Verneuil (naturalist), Henry James Johnston Lavis (volcanologist).Published667-6775.2.

The relationship between viso-motor skills and handwriting in students with dyslexia
No full textAim: To relate the viso-motor skills and handwriting of students with dyslexia. Methods: Twenty-two students with multidisciplinary diagnosis of dyslexia, aged from 8 years and 3 months to 13 years and 4 months, of both genders, from third to fifth grade of elementary school participated in this study. The students were submitted to the following procedures: Visual Perception Development Test III - DTVP III and Dysgraphia Scale. Results: The results indicated that most students with dyslexia were classified as dysgraphics. Therefore, from the analysis of the Visual Perception Development Test (DTVP-III) it was possible to observe that there was an impact of the variables related to the visomotor and fine motor skills. Conclusion: Nevertheless, the findings of this study indicate that dyslexic students presented difficulties in visomotor skills, thus impairing hand writing. Thus, most of these students presented compatible performance for disgraphic writing
Evolution of the intermixing process in Ge/Si(111) self-assembled islands
No full textIn this contribution we present a study of the Ge-Si intermixing process that arises during the growth of Ge/Si(111) self-assembled islands. The samples, grown by means of a molecular beam epitaxy (MBE)-like technique, have been characterized by in-situ scanning tunneling microscopy (STM) and atomic force microscopy (AFM) complemented by ex-situ X-ray absorption fine structure (XAFS). We have observed by STM a change in the island morphological evolution, from truncated tetrahedra to atoll-like islands, that can be related to the misfit the reduction effect induced by the intermixing process. We have evaluated the intermixing by measuring the average coordination numbers of Si and Ge around a Ge atom by XAFS. We show that the Si content in the nominally pure Ge wetting layer reaches 50% while in the three-dimensional (3-D) islands it is about 25%, and that the intermixing increases with increasing deposition temperature in the 450-530 degreesC range
Radiative and non-radiative recombinations in tensile strained Ge microstrips: Photoluminescence experiments and modeling
No full textTensile germanium microstrips are candidate as gain material in Si-based light emitting devices due to the beneficial effect of the strain field on the radiative recombination rate. In this work, we thoroughly investigate their radiative recombination spectra by means of micro-photoluminescence experiments at different temperatures and excitation powers carried out on samples featuring different tensile strain values. For sake of comparison, bulk Ge(001) photoluminescence is also discussed. The experimental findings are interpreted in light of a numerical modeling based on a multi-valley effective mass approach, taking in to account the depth dependence of the photo-induced carrier density and of the self-absorption effect. The theoretical modeling allowed us to quantitatively describe the observed increase of the photoluminescence intensity for increasing values of strain, excitation power, and temperature. The temperature dependence of the non-radiative recombination time in this material has been inferred thanks to the model calibration procedure
