Investigation on the pollen morphology of traditional cultivars of Prunus species in Sicily

2012

In this study pollen grains of 13 cultivars and 3 rootstocks belonging to 5 species (<em>P. armeniaca</em>, <em>P. domestica</em>, <em>P. dulcis</em>, <em>P. persica</em>, <em>P. avium</em>) of the genus <em>Prunus </em>collected from North-East Sicily were examined for the micromorphological characterization through the scanning electron microscopy (SEM). The length of polar axis (<em>P</em>) and the equatorial diameter (<em>E</em>) of grain, <em>P/E </em>ratio, the length of colpi (<em>C</em>), diameter of perforations (<em>DP</em>) and the number of perforat…

Morphology modification of a polyethylene/clay nanocomposite samples under convergent flow

2009

The morphology of PE/CL nanocomposite samples subjected to convergent flows is studied. Elongational flow – the typical flow involved in spinning and film-blowing processing operations – significantly increases with the reduction of the capillary diameter. The values of the convergent extensional stress (calculated by Cogswell's formula) for the PE/CL systems, for all the adopted capillary geometries, are greater than the calculated values for pure polyethylene. The applied convergent flow, at the entrance of the capillary, is able to change the clay morphology and consequently the final material properties on the PE/CL system with limited affinity between the matrix and organo-modified cla…

Glossary of Morphology

2020

This book is a significant novelty in the scientific and editorial landscape. Morphology is both an ancient and a new discipline that rests on Goethe's heritage and re-forms it in the present through the concepts of form and image. The latter are to be understood as structural elements of a new cultural grammar able to make the late modern world intelligible. In particular, compared to the original Goethean project, but also to C.P. Snow's idea of unifying the “two cultures”, the fields of morphological culture that are the object of this glossary have profoundly changed. The ever-increasing importance of the image as a polysemic form has made the two concepts absolutely transitive, so to s…

Morphology, Plasticity, and Transformation between Philosophy and Biology

2020

In biology, interest in form was the prerogative of developmental biology, while it was practically neglected by evolutionary biology. This situation has changed a lot in recent decades and has led to a reinterpretation of the concept of evolution and evolutionism focusing more on the problem of form and morphology. In Italy, especially Alessandro Minelli, one of the editors of this issue, has dedicated his studies to the need to communicate form to structure, to reconnect morphology and evolution. This theme is a highly relevant one for philosophy, inasmuch as the question of form and morphology, since the days of Goethe and Bergson, has always been considered as the starting point for a p…

Verkörperung: Bild und Experiment bei Edgar Wind und die aktuelle Lage der morphologischen Forschung

2021

Edgar Wind’s The Experiment and Metaphysics examines, in the sense of Goethe’s morphological project, the common structures of scientific and artistic thinking in the light of the reflective value of the image and the technological processes of research and construction of reality. In Wind’s philosophy of em- bodiment the image plays a role in the artistic field comparable to the function of experiments in science. The picture is neither a ‘copy’ nor just a ‘part’ of reality, but rather an ‘embodiment’: at the same time the ‘result’ of human activity and a ‘condition’ for all interpretation of the world. It opens up as an embodiment to a temporality which is not just linear but ‘configured’…

Morphometry of Middle Bronze Age palstaves by discrete cosine transform.

2009

9 pages; International audience; The Discrete Cosine Transform (DCT) is a Fourier-related transform widely used in signal processing and well suited to the analysis of open outlines. This method was applied here to evaluate the discrimination power of the inner lateral rib for two palstave populations dating from the Middle Bronze Age, excavated in northwest France. A corpus of almost 400 palstaves (bronze axes) of the Breton and Norman types was processed, and compared to specimens found at Sermizelles in Burgundy. The procedure is robust and produces a discrimination in good agreement with the traditional typology. Besides the definition of a ‘standard' shape for each population, the morp…
