St. Augustinegrass accessions planted in northern, central and southern Italy: Growth and morphological traits during establishment
2018
The use of warm season turfgrasses is a consolidated trend in the climatic transition zone of Mediterranean countries, in particular St. Augustinegrass (Stenotaphrum secundatum (Walt.) Kuntze) begins to be widespread in warm coastal areas. However, little is known about the performance of the different cultivars of this species in southern Europe. In 2016-2017 a trial was carried out in three locations in Italy, Padova, Pisa, and Palermo, located in the north, center and south of the country respectively. Four cultivars (Floratine, Captiva, Sapphire, Palmetto) and five ecotypes (CeRTES 201, CeRTES 202, CeRTES 203, CeRTES 204, CeRTES 205) were compared in terms of their growth characteristic…

CNGB3 mutations account for 50% of all cases with autosomal recessive achromatopsia
2005
Contains fulltext : 47591.pdf (Publisher’s version ) (Closed access) Achromatopsia is a congenital, autosomal recessively inherited disorder characterized by a lack of color discrimination, low visual acuity (<0.2), photophobia, and nystagmus. Mutations in the genes for CNGA3, CNGB3, and GNAT2 have been associated with this disorder. Here, we analyzed the spectrum and prevalence of CNGB3 gene mutations in a cohort of 341 independent patients with achromatopsia. In 163 patients, CNGB3 mutations could be identified. A total of 105 achromats carried apparent homozygous mutations, 44 were compound (double) heterozygotes, and 14 patients had only a single mutant allele. The derived CNGB3 mutatio…
Molecular characterization and Phylogenetic analysis of Turnip mosaic virus (TuMV) in Erysimum linifolium L. in Italy
2013
In the Summer of 2012, Erysimum linifolium L. pot plants produced at an ornamental grower in Liguria region (northern Italy), showed unusual virus-like disease of dark mottle and stripes on mauve-purple petals. A virus was mechanically transmitted from symptomatic flowers to several test plant species belonging to Chenopodiaceae and Brassicaceae families. This virus was identified as an isolated of turnip mosaic virus (TuMV) by PAS-ELISA analysis, electron microscopy negatively stained crud extracts and immuno-electron microscopy (IEM) tests. In the naturally infected E. linifolium plants, TuMV occurred alone, since any other viruses either by electron microscopy or mechanical inoculations …
Alchimia e Memphis. I colori progettati del design
2012
Il design italiano, tra anni Settanta e Ottanta, viene marchiato a fuoco dalla definizione “Made in Italy” che ne riporta provenienza geografica, qualità progettuale e innovativa ed eccellenza assoluta. In tale scenario, all’interno di tante realtà legate al design e diffuse capillarmente sul territorio, si continua a sperimentare in modo ininterrotto, e in ogni settore legato alla progettazione, alla produzione, alla ricerca tecnologica e dei nuovi materiali. Scenario nel quale si muovono anche le realtà di Alchimia e Memphis che ripensano il progetto, attribuiscono nuovo valore a elementi come il colore e la decorazione, costruiscono nuovi lessici. In the 1970s and 1980s, the identity of …
Machine learning for rapid mapping of archaeological structures made of dry stones – Example of burial monuments from the Khirgisuur culture, Mongoli…
2020
11 pages; International audience; The present study proposes a workflow to extract from orthomosaics the enormous amount of dry stones used by past societies to construct funeral complexes in the Mongolian steppes. Several different machine learning algorithms for binary pixel classification (i.e. stone vs non-stone) were evaluated. Input features were extracted from high-resolution orthomosaics and digital elevation models (both derived from aerial imaging). Comparative analysis used two colour spaces (RGB and HSV), texture features (contrast, homogeneity and entropy raster maps), and the topographic position index, combined with nine supervised learning algorithms (nearest centroid, naive…
Small anthropomorphic figurines in clay at Gipka neolithic settlements:
2005
Miniature Neolithic figurines in clay are a special topic of research. This especially concerns areas where their representation has so far been poor. While carrying out archaeological excavations in Northern Kurzeme, the north west coastal dune yone of Riga Bay, a ritual-like complex was recovered at Gipka A site belonging to the local Culture of Pit Ceramics. It consists of several large and smaller fireplaces and pits, with the finds of fragmentary clay figurines recovered under the palisade that surrounded the settlement. The head and body of the miniature anthropomorphic figurines in clay have original modelling. It is possible to single out two types of figurine: with rather broad che…
Spectroscopic analysis used to uncover the original paint colour of the Helsinki Government Palace tower clock faces
2016
The paint stratigraphy of the two clock faces from the tower clock of the Government Palace in Helsinki (Finland) was analysed in order to determine their original colour before restoration works. Paint cross-section samples from both clock faces were analysed by confocal Raman microscopy and scanning electron microscopy coupled to an energy dispersive X-ray spectrometer (SEM-EDS). The results revealed the complex superimposition of paint layers applied over the original black colour. FTIR/ATR analyses proved that the original paint was prepared with linseed oil-resin media. Most likely not all of the different layer colours were visible. Some of the layers were likely to have been a primer…
I ‘vasi di Centuripe’: per un approccio integrato
2017
Il contributo intende evidenziare le prospettive di un approccio interdisciplinare integrato allo studio della ceramica policroma “di Centuripe”. Dagli inizi del XX secolo, tale classe ha riscosso ampio apprezzamento per le sue delicate pitture e la ricchezza di ornamenti a rilievo applicati (dipinti e dorati) che abbelliscono i vasi, rendendoli pressoché inutilizzabili nella pratica per scopi funzionali, ma altamente efficaci come doni funerari in antico, e oggi come pezzi di grande impatto per commercianti di antichità e collezionisti moderni. Data la piaga, diffusa fino a tempi recenti, degli scavi clandestini, dei “restauri” arbitrari e delle falsificazioni, i vasi di Centuripe necessit…
Hymenoptera Chalcidoidea inhabiting galls of Cynipidae in Jordan
2009
Twenty-three species of Chalcidoidea (5 Eurytomidae, 4 Torymidae, 2 Ormyridae, 5 Pteromalidae and 7 Eulophidae) are recorded as regular members of the parasitoid fauna inhabiting galls of Cynipidae in Jordan. The occurrence of three additional species, probably only facultatively associated with cynipid galls, is noted. Twenty-two out of the total 26 species were previously unrecorded in the country, while 13 of them are also new for the entire Middle East. Eighteen new host records were detected, together with 24 new plant-parasitoid associations. The biology of each species is briefly commented upon, as well as the presence of a host-related colour variation in some species.
