Approche géoarchéologique sur la nécropole monumentale d'Escolives-Ste-Camille (Yonne): un site en bordure d'un chenal de l'Yonne à l'époque néolithi…
2006
Die Herausbildung des Mittelneolithikums I Cerny wird im Südosten des Pariser Beckens von dem Auftauchen monumentaler Nekropolen in den Sohlen von Flusstälern begleitet. Die Eingliederung dieser Bestattungsplätze in die Landschaft lässt eine ausdrückliche Absicht erkennen und tradiert möglicherweise den Anspruch einer Gruppe, ihr Gebiet deutlich als das ihre auszuweisen. Vor diesem Hintergrund waren die Ausgrabungen der Nekrolpole von Escolives-Sainte-Camille ‘La Pièce de l'Étang’ von Untersuchungen begleitet, welche die Umgebung des Fundplatzes in neolithischer Zeit bestimmen sollten. Es ging darum, die Einfügung des Platzes zwischen zwei Paläorinnen in ihrem hydrographischen Milieu zu rek…
BIOAVAILABILITY TO JUVENILE RAINBOW TROUT (ONCORYNCHUS MYKISS) OF RETENE AND OTHER MIXED-FUNCTION OXYGENASE-ACTIVE COMPOUNDS FROM SEDIMENTS
2002
Retene (7-isopropyl-1-methylphenanthrene) is a naturally formed polycyclic aromatic hydrocarbon (PAH) that causes teratogenicity in fish larvae and induction of cytochrome P450 (CYP1A) enzymes. Retene occurs at high concentrations (or =3,300 microg/g dry wt) in surface sediments contaminated by resin acids from pulp mill effluents. To assess the environmental risks of retene, it is important to evaluate conditions affecting its bioavailability and accumulation by fish. Fingerling rainbow trout were exposed to retene-spiked or naturally contaminated sediments and sampled after 4 d to determine liver CYP1A activity and concentrations of retene metabolites in bile as indicators of retene accum…
Prove di coltivazione di Camomilla comune (Chamomilla recutita Rausch.) nell’ambiente semiarido mediterraneo.
2009
La Camomilla comune (Chamomilla recutita (L.) Rausch) è una pianta erbacea annuale originaria del sud-est asiatico, che oggi, grazie alle sue riconosciute proprietà calmanti e sedative, è largamente diffusa e coltivata in tutto il mondo. In tempi recenti, un forte interesse verso la specie deriva anche dalla sua possibilità di utilizzazione in svariate branche dell’industria, dalla farmaceutica (che ne sfrutta le proprietà sedative e antinfiammatorie), alla cosmetica (che la utilizza per la preparazione di creme, detergenti, profumi e shampoo), all’alimentare (che ne fa uso per bevande, dolci, gelati, liquori e vermouth). La larga diffusione della specie fa sì che in larga parte la sua tecn…
Use of standard and setup of non conventional techniques for the elimination of viruses associated with Fig Mosaic Disease (FMD) in fig germplasm (Fi…
2017
Abstract Ficus carica L. is considered one of the oldest fruit trees in the Mediterranean basin and is widely grown and harvested for the consumption of its fruits dry and fresh. This species is affected by different virus diseases, especially by Fig mosaic disease (FMD), for which Fig leaf mottle-associated virus 1 (FLMaV-1), Fig leaf mottle-associated virus 2 (FLMaV-2), Fig mild mottling-associated virus (FMMaV), Fig mosaic virus (FMV), Fig latent virus 1 (FLV-1), Fig badnavirus 1 (FBV-1) and Fig fleck-associated virus (FFkaV) are associated. FMD is the most widespread disorder of this species, which represents a threat and a constraint for healthy fig production and germplasm exchange. T…
Analysis of S-allele genetic diversity in Sicilian almond germplasm comparing different molecular methods
2015
Italian almond germplasm is characterized by a wide diversity in several growing areas among which Sicily is one of the most important. Analysis with consensus and specific primers and DNA sequencing was performed to investigate S-RNase genetic diversity and to elucidate the homology rate within a genetic pool of 27 Italian accessions. Interestingly, some of the self-compatible cultivars did not show the presence of Sf allele. Amplicons from consensus and allele-specific PCR primers revealed a high level of variability. Sequencing of all the S-RNase amplicons derived from consensus primers allowed the identification of two new S-RNase alleles (S51 and S52). Surprisingly, despite the AA repl…
Estimation of aerobic fitness among young men without exercise test
2015
Summary Study aim: to develop and estimate the validity of non-exercise methods to predict VO2max among young male conscripts entering military service in order to divide them into the different physical training groups. Material and methods: fifty males (age 19.7 ± 0.3 years) reported their physical activity before military service by IPAQ and SIVAQ questionnaires. Furthermore, Jackson’s non-exercise method was used to estimate VO2max. Body mass and height were measured, body mass index calculated and VO2max measured directly in a maximal treadmill test. Subjects were randomly divided into two groups. The results of the Group 1 (N = 25) were used to develop a regression equation to estimat…
Caddis larvae (Trichoptera, Hydropsychidae) indicate delaying recovery of a watercourse polluted by pulp and paper industry
2012
Abstract We studied ecotoxicological responses of aquatic insects to evaluate the recovery of a watercourse with a history of over 100 years as a recipient of pulp and paper mill effluents. The recovery of the water quality began in 1985 due to the improved technology, but ecotoxicological effects on biota have still been evident two decades later, as indicated by morphological abnormalities in tracheal gills of caddis larvae. We hypothesized that these abnormalities are related to organic contaminants, such as resin acids, alkylated PAHs and chlorinated organic compounds, released historically from the mills, and more recently via resuspension from the sediment. Samples were collected betw…
The effects of treated effluents on the intensity of papillomatosis and HSP70 expression in roach.
2008
Epidermal papillomatosis in fish has been proposed as an indicator of environmental stress but experimental evidence of connection between contaminants and papillomatosis in fish is scarce. We studied changes in the intensity of epidermal papillomatosis and the expression of heat shock protein 70 (HSP70) in roach, Rutilus rutilus, exposed to treated pulp mill and municipal effluents. In male roach, the increase in papillomatosis intensity was higher in fish exposed to 15% than in fish exposed to 1.5% concentration of municipal effluent. No differences were observed in papillomatosis development in females, or in HSP70 expression. In all the experiments conducted, the increasing effect of ef…
Effects of primary- and secondary-treated bleached kraft mill effluents on the immune system and physiological parameters of roach.
2000
The present study was designed to examine, whether, effluents from a modern pulp and paper mill using elemental chlorine-free/total chlorine-free (ECF/TCF) bleaching, exert effects on the immune system of fish and, in addition, to relate these findings to physiological parameters known to be affected by bleached kraft-mill effluents (BKME). Roach (Rutilus rutilus) were exposed in laboratory conditions to primary- or secondary-treated effluent from a pulp and paper mill. In order to study their capability to respond to foreign antigens they were immunised with bovine gamma-globulin (BGG) prior to exposure. The number of anti-BGG antibody-secreting cells (ASC) and the number of immunoglobulin…
Il Mezzogiorno di Bandi e Abba tra esotismi e stigmatizzazioni
2014
Ad eccezione di taccuini, articoli di giornale o lettere, la maggior parte dei memorialisti garibaldini si dedicò alla scrittura solo alcuni anni dopo le imprese della Spedizione dei Mille. Considerando la provenienza non meridionale della maggior parte di loro, è interessante vedere come il Sud sia stato per lo più caratterizzato in senso esotico e memoriale: luogo misterioso e fonte di stereotipi, cullato nella memoria e testualizzato attraverso una scrittura che esalta il dato leggendario.
