Homonoia - Concorda - Sammanasya
No full textAnalysis of the divine figures of Homónoia in the Greek pantheon, Concordia in the Roman pantheon, and Sammanasya in the Vedic pantheon. Claudia Santi is the author of Homónoia; Andrzej Gillmeister is the author of Concordia; Antonio Salvati is the author of Sammanasya. As regards Homónoia, the origin of this personified abstraction seems to be traced back to the political debate of Athens in the last 5th century. Maybe it was created by Antiphon as opposed to stásis, both in the meaning of ‘psychic conflict’ and ‘internal political dissensions, civil war’

Influence of micro injection moulding process parameters on mechanical characteristics of POM and POM/CNT composites
No full textMicro injection moulding is one of the most used thermoplastic technology for the manufacturing of miniaturized products, due to the high productivity of the process. Thermoplastic micro manufacturing has reached nowadays an incredible spread: polymeric components are used in several fields, such as biomedical, IT, telecommunication, automotive and aerospace. In recent years, an innovation in polymer area was the addition of fillers on the pure polymer, in order to improve the physical properties and/or to reduce the cost of the composite.
The aim of the present work is to carry out a comparison between the mechanical properties of POM base material and POM filled with carbon nanotubes micro injected using different process parameters - melting temperature, injection speed and holding pressure. Uniaxial mechanical tests were performed to obtain the main mechanical properties: yield stress, deformation at break and stress at break.
The results, analyzed with Analysis of Variance statistical approach show that the mechanical response of the micro¬ specimens is mainly affected by the CNT presence, whereas the other factors seems to play only a secondary role. The presence of CNT induces a remarkable increase in the mechanical resistance, but drastically reduces the material ductility
OPTICAL CHARACTERIZATION OF MINERAL DUST CONTENT IN SNOW AND ICE CORES WITH DIGITAL IN-LINE HOLOGRAPHY
No full textAerosols are ubiquitous in the troposphere and influence the global climate by changing the radiative properties of the atmosphere: directly, through the scattering and absorption of solar and terrestrial radiation, and indirectly acting as cloud condensation and ice nuclei formation. Although extensive research has been carried out on this topic, significant uncertainties still affect current estimates of this contribution on the Earth’s energy balance.
In this work, I studied the effects of the particle shape on the optical parameters for the radiative transfer through the atmosphere. I present the results of the characterization of mineral dust and micrometric particles transported and subsequently deposited on the surface of glaciers, and in time brought deeper, layer after layer. To this end, digital microscopic holography has proven to be an excellent suite for distinguishing non-spherical particles, going beyond the common spherical approximation. From the interference between the trans-illuminating reference field and the diffracted light by the particles in the forward direction, the cross-sectional area and the extinction cross-section can be numerically retrieved, thus providing a multi-parametric single-particle approach.
This work develops a formal description of the technique through the theory of image formation in holographic microscopy, reporting a suite of validation measurements with calibrated particles, and providing an overview of the experimental results from Antarctic and Alpine snow and ice cores. The analysis reveals a remarkable variability in the extinction cross-section of the particles depending on their shape, with a prevalence of non-spherical particles, which proves the importance of measuring morphological and optical properties simultaneously. I also observed a prevalence of fine particles (< 2 μm in size), with the occurrence of aggregates and some giant particles (> 10 μm in size), especially in Alpine snow cores.
Currently, global and regional models assume dust particles as uniform spheres, and neglect the coarsest particles, introducing biases in the estimation of the radiative effects. Therefore, they will benefit from more accurate modeling of particle size and shapes, especially if obtained from the optical properties themselves

Optical Characterization of Mineral Dust from the EAIIST Project with Digital Holography
No full textWe describe an optical approach based on Digital Holography for single-particle characterization of mineral dust and micrometric particles, focusing on the analysis of airborne particles in meltwater from Antarctic ice cores. We record the holograms formed by the superposition of the transilluminating reference beam and the waves scattered by single particles. Taking a cue from recent approaches in the field and holography methods, we process the holograms to recover both optical and morphological properties of single dust grains. As a considerable advantage over traditional light-scattering-based methods, holograms give the extinction cross section of each particle and, by numerically reconstructing the wavefront propagation, an unambiguous image of each particle whereby we derive its cross-sectional shape and size. Measurements have been carried out on samples collected from the recent EAIIST (East Antarctic International Ice Sheet Traverse) project, some of which show evidence of volcanic events. The vast majority of the detected particles show significant deviations from the isometric shape, as confirmed by both image reconstruction and extinction cross section analysis. By our analysis, we observe that experimental data have an extinction cross section up to 3 times lower than that of spherical particles with the same volume. Therefore, these deviations have an appreciable impact on the aerosol contribution to radiative forcing: retrieving particle shape may improve the modeling of the radiative properties of mineral dust and reduce the associated uncertainties
