    No full text
    2 volumes ; in 2 cases. Plaster cameos reproducing works of classical and contemporary sculpture, produced by the firm of Paoletti, at Rome, circa 1865. The cameos are organized and mounted in trays housed within 8 faux book bindings, with a tray of cameos underneath both the front and back cover of each volume. Each cameo is numbered in pen and ink, and in turn identified in manuscript on the inside covers of each volume. All volumes bound in quarter vellum, with green boards. The title Paoletti impronte is gilt-stamped on a red morocco title label at the head of the spine. On a similar label at the foot of each spine, a title for the contents of the volume is stamped in gilt; the contents are as follows: Uomini illustri ; Musei Diversi. Plaster cameos such as these were popular souvenirs for British travelers on the Grand Tour of the continent. As in the present set, they were frequently mounted in faux book bindings. Paoletti begs to inform the public that he has arranged a collection of impressions .. of many of the works in sculpture executed by distinguished artists, whose works are described by the Count Hawks le Grice in the above interesting and instructive \u27Walks\u27 ; he has also executed impronte taken from the portraits of the author, of Thorwaldsen, Gibson, Wyatt, Wolff etc., all of which have been executed in cameo by Saulini, a distinguished Roman engraver. The impressions are bound up in 3 vol. 4o, and form an appropriate companion to the Count\u27s work .. --Advertisement on page 269 (volume 1) of Le Grice\u27s Walks through the Studii of the sculptors at Rome (Rome : C. Puccinelli, 1841). The address of Paoletti\u27s shop is noted in volumes 1 and 3 of the present set. Paoletti is listed at 86 Via della Croce in at least two contemporary directories: A handbook of Rome and its environs (London : John Murray, 1864); and, Rome seen in a week (Rome : L. Piale, 1865). Paoletti\u27s studio, during the lifetime of Pietro Paoletti (1801-1847), was previously at 49 Piazza di Spagna, Rome. Bartolomeo Paoletti, an antique dealer and engraver in Rome, began the Paoletti collection of plaster casts of intaglios and cameos between 1760 and 1770. In 1834 his son Pietro took over the business. Volume [1]. Uomini illustri ; volume [2] Musei Diversi. Case edges printed in a marbled pattern. Contents of each volume listed inside cover.

    ABSTRA CT Contrib. Nat. Hist. 12: 461–488. Folk traditional diets in Western Friuli include wild plants and few invertebrates (i.e. insects) that are peculiar in the Southern Alps. 156 plants are listed here, ranging from 200 m to 2200 m a.s.l.. This selection is the result of the research of 64 informants who contributed with their personal experiences. Recovery of scattered knowledge is valuable for maintaining and sustaining its use and enhancing a wild biodiversity base for agroecology, conservation and ecotourism. Pistiç, frita and lidùm are some of the names used for about 50–60 herbs collected in field margins, hay meadows, woodlands and the wild, most commonly in spring. In order to be consumed, most herbs are boiled together and are later sautéed with butter or lard and garlic. The higher range pre-alpine Carnic slopes have supported seasonal sheep and cow grazing and summer pastoral communities have traditionally used plants as well for salads, soups and spices in addition to the boiled-sautéed dish. Furthermore, herbs have been used as medicinal elixirs and for milk processing. For instance, Lycopodium annotinum L. was employed to filter milk; Asplenium ruta-muraria L. was cooked with maize flour to prepare "fregole" a dish eaten with milk or coffee made from barley. Specifically, collections of these useful alpine plants include: Chenopodium bonus-henricus L., Aruncus dioicus (Walter) Fernald, Cicerbita alpina (L.) Wallr., Rumex alpinus L., Carlina acaulis L., Myrrhis odorata (L.) Scop., Ranunculus hybridus Biria (dry leaves used as pepper), and raw bulbils of Polygonum viviparum L. Some parts or products of insects were also eaten in these summer meadow areas ("magredi") and hay meadows such as the ingluvies of adult Lepidoptera (Zygaenidae Zygaena spp. and Ctenuchidae Syntomis spp.). Bees such as Bombus sp. were exploited for honey content in their ingluvies and their nests were exploited for honey. The pollen and nectar deposits of Osmia sp. inside snail shells were eaten as a snack. Of the grasshopper Decticus verrucivorus (L.) at least the prominent femurs were eaten raw. These local traditional habits need further ethnobiological attention and nutritional study since the loss of practical experience in collecting these 462 Angelo L. Dreon & Maurizio G. Paoletti fragments of biodiversity make their memory prone to be lost. The highest number of plant species found in Friuli is associated to the highest amount of wild plants offered in this region by specialized restaurants (Osterie) in the Northern regions of Italy

    The in-vitro response of pollen germination and tube length to different types of acidity

    No full text
    Pollen germination and tube growth are among the most sensitive responses to atmospheric pollution. Both these are inhibited by the acidity of the growth medium. Pollen grains from two species (Pinus cembra L. and Sambucus nigra L.) were germinated in media over a range of pHs (5·0, 4·5, 4·0, 3·5, 3·0 and 2·5) and six types of acidity (H2SO4, HNO3, H2SO4: HNO3 in 1:1, 2:1, 3:1 and 5:1 ratio). Pollen of the Gymnosperm is shown to be more resistant to acidity in the medium. Sulphuric acid alone and the ratio 2:1 with nitric acid are demonstrated to be the more harmful for P. cembra and S. nigra, respectively. The latter species was sensitive to all mixtures, particularly in respect to germination percentage

    Volpato, Gabriele, Rossella Marcucci, Noemi Tornadore, and Maurizio G. Paoletti (Department of Biology, University of Padua, 325100 Padova, Italy; email corresponding author: [email protected]). DOMESTICATION PROCESS OF TWO SOLANUM SECTION LASIOCARPA SPECIES AMONG AMERINDIANS IN THE UPPER ORINOCO, VENEZUELA, WITH SPECIAL FOCUS ON PIAROA INDIANS. Economic Botany 58(2):000–000, 2004. Two semi-cultivated Solanum species (S. sessiliflorum Dunal and S. stramonifolium Jacq.) are utilized by the Amazonian Indians of the Upper Orinoco Basin in Venezuela. The manner by which they have become partially domesticated by the Piaroas and other native tribes of this rain forest region is elucidated in the following text. Both species have two varieties, with and without prickles, the latter the result of human selection. Patterns of indigenous utilization of these species by the selection of morphologic forms and to the differentiation of karyotypes of varieties, and exploitation of the species reflects also in the perception of them among users. S. sessiliflorum is cultivated in swiddens and has an economic role, whereas S. stramonifolium is grown in dooryards. This difference is detectable to the Piaroas, as they recognize in their folk taxonomy three different varieties of the S. sessiliflorum and one of S. stramonifolium, this according to the stage of domestication of the species and the way in which they are utilized

    Experimental evidences of counterion affinity in alginates: the case of nongelling ion Mg2+

    No full text
    The present contribution aims at testing experimentally the theoretical model previously devised (Donati, I.; Cesaro, A.; Paoletti, S.; Biomacromolecules 2006, 7, 281-287) for the description of the interaction between alginate and nongelling Mg2+ ions. The model, based on an extension of the counterion condensation theory, introduces a contribution of free energy of affinity, (Delta G) over bar (aff,0), which depends on the monomer composition of the polyuronate. In the present work, three different alginates separately mimicking the mannuronan (polyM), the guluronan (polyG), and the polyalternating (polyMG) components of alginate, together with a natural alginate isolated from Laminaria hyperborea (L. hyperborea), were examined. They were treated with Mg2+ ions, and relative variations in scattered light intensity, isothermal calorimetry (Delta H-mix) specific viscosity, and Na-23 NMR longitudinal relaxation rates were monitored with respect to samples at the same ionic strength but containing only Na+ ions. The fraction of condensed magnesium counterions was found to be strongly dependent on alginate composition, increasing along the series mannuronan < polyalternating similar to L. hyperborea < guluronan, thus in good agreement with the theoretical predictions

    Encircling of Metal Ions by Tetraaza Macrocycles. Enthalpies of Formation of High and Low-spin Nickel(II) Complexes of 14-Membered Ligands

    The heats of formation of high- and low-spin Ni(II) complexes with 1,4,7,11-tetraazacyclotetradecane (L; chelate ring sequence 5,5,6,6) were detd. calorimetrically in aq. soln. The chelation reactions with L are less exothermic than those with the isomeric 1,4,8,11-tetraaza ligand (chelate ring sequence 5,6,5,6) due to a decrease of the in-plane Ni-N interaction. Insertion of a pyridine ring into the ligand framework makes chelation much less exothermic

    Ancora su Vico e gli Ebrei

    No full text
    La posizione di Vico sugli ebrei è stata oggetto di valutazioni diverse e talora persino opposte. I commentatori di Vico si sono chiesti se nel rapporto fra gli ebrei e le nazioni gentili prevalgano i tratti di omogeneità o quelli di eterogeneità; se le differenze che Vico sottolinea comportino anche un’assoluta separazione oppure se consentano di stabilire una relazione; eventualmente, di che relazione si tratti. Alcuni hanno visto negli ebrei e nella loro storia il modello di un'umanità compiuta; per altri invece gli ebrei e la storia sacra si caratterizzano per la loro marginalità rispetto alla storia delle nazioni ricostruita nella Scienza nuova. Uno studio della stratificazione delle tre edizioni dell’opera permette di vagliare questa semplice ipotesi: che la diversità di valutazioni di cui il ruolo degli ebrei in Vico è stata oggetto sia dipesa anche dal fatto che Vico stesso non ha sempre espresso la medesima opinione in proposito

    Edible Invertebrates among Amazonian Indians: a critical review of Disappearing Knowledge

    No full text
    For the indigenous populations of Amazonia, invertebrates constitute an important component of the diet. Information on entomophagy for 39 ethnic groups (and three other post-Columbian settlers) or about 21.4% of the 182 groups known in the Amazon Basin is presented here, but utilization of this non-conventional food resource is surely much more widespread. A database is given of all the information available for each ethnic group regarding the species included in the diet, scientific and the ethno name if known, stage of life cycle consumed, manner of preparation and, when known, host plant. This database lists 209 scientifically identified species. Information on an additional 426 species and ethno names, with an insecure link to Linnean taxonomy suggest that local knowledge is very extensive. The database represents not only an easy-to-consult resource, but also a support for further research. Caterpillars, termites, leafcutter ants, bees, wasps, and Coleoptera seem to be the more collected items, together with a few aquatic ones. The most intensively collected are those dependent on forest leaves and litter, representing in general the higher biomass, so much work needs to be done for other groups, including caterpillars, aquatic insects, grasshoppers, snails, and spiders. Knowledge of the relations between indigenous populations and ecosystems is indeed the base for the preservation of natural and cultural biodiversity. We are at the beginning of a survey that has to be expanded
