A revision of the shore-fly genus Hydrochasma Hendel (Diptera, Ephydridae)
2013
A revision of the shore-fly genus Hydrochasma Hendel. The species of the genus Hydrochasma Hendel are revised, including 27 new species (type locality in parenthesis): H. andeum (Ecuador. Guayas: Boliche (02°07.7'S, 79°35.5'W)), H. annae (United States. Utah. Grand: Swasey Beach (15.3 km N Green River; 39°07'N, 110°06.6'W; Green River; 1255 m)), H. capsum (Ecuador. Orellana: RíoTiputini (0°38.2'S, 76°8.9'W)), H. castilloi (Ecuador. Loja: Catamayo (03°59'S, 79°21'W)), H. crenulum (Peru. Cuzco: Paucartambo, Atalaya (Río Alto Madre de Dios; 12°53.3'S, 71°21.6'W; 600 m)), H. denticum (Ecuador…
LA QUALITÀ DEL MANGO PRODOTTO IN SICILIA, ASPETTI COLTURALI DELLA PAPAYA, DEL LICI E DEL NESPOLO DEL GIAPPONE
2016
L’introduzione di specie arboree da frutto di origine tropicale e subtropicale in Sicilia non è nuova ma solo negli ultimi anni si assiste ad una crescita esponenziale delle superfici investite. Infatti, se alberi come il Nespolo del Giappone fanno ormai parte della nostra cultura frutticola da decenni, mango, lici e papaia fino a qualche anno fa erano poco conosciuti sulle nostre tavole. Nel giro di poco tempo questi frutti hanno conquistato un posto stabile tra le preferenze del consumatore con spazi di mercato in continuo aumento. La coltivazione di questi fruttiferi di origine tropicale presuppone precise risposte sulla fattibilità di nuovi impianti e sulle modalità di conduzione agrono…
Data from: Population structure and reticulate evolution of Saccharomyces eubayanus and its lager-brewing hybrids
2014
Reticulate evolution can be a major driver of diversification into new niches, especially in disturbed habitats and at the edges of ranges. Industrial fermentation strains of yeast provide a window into these processes, but progress has been hampered by a limited understanding of the natural diversity and distribution of Saccharomyces species and populations. For example, lager beer is brewed with Saccharomyces pastorianus, an alloploid hybrid of S. cerevisiae and S. eubayanus, a species only recently discovered in Patagonia, Argentina. Here we report that genetically diverse strains of S. eubayanus are readily isolated from Patagonia, demonstrating that the species is well established ther…
Measurement of the single-top-quark production cross section at CDF.
2008
We report a measurement of the single top quark production cross section in 2.2 ~fb-1 of p-pbar collision data collected by the Collider Detector at Fermilab at sqrt{s}=1.96 TeV. Candidate events are classified as signal-like by three parallel analyses which use likelihood, matrix element, and neural network discriminants. These results are combined in order to improve the sensitivity. We observe a signal consistent with the standard model prediction, but inconsistent with the background-only model by 3.7 standard deviations with a median expected sensitivity of 4.9 standard deviations. We measure a cross section of 2.2 +0.7 -0.6(stat+sys) pb, extract the CKM matrix element value |V_{tb}|=0…
AES and CEMS analysis of the formation of layers on Si steel under thermal treatment in a flux of H2/water vapour
1991
The near surface diffusion and reaction processes in iron-silicon steel (3.1 wt.%Si) during 10 min decarburization in water vapour/hydrogen have been studied. The decarburization temperature has been varied between 506 and 714°C for the fixed partial pressure ratio pH2O/pH2=0.017. An outer layer of SiO2 forms on the surface with its thickness increasing with temperature. From 600°C upwards, the decarburization process is hindered and a cementite layer is formed below the SiO2 layer. The formation of fayalite at the surface has been studied at a fixed decarburization temperature with pH2O/pH2 ranging from 0.017 to 0.49. The scale thickness reduces abruptly just before the ratio pH2O/pH2 nece…
Cell Immunity in Inflammatory Vasculitis
2015
The vasculitides are a highly heterogeneous group of disorders characterized by the presence of inflammatory leukocytes in the vessel walls and reactive inflammation. Giant cell arteritis (GCA) and Takayasu’s arteritis (TA) are the two primary large-vessel vasculitides. Two distinct cellular pathways have been identified in GCA: Th17 polarization and IL-17 secretion and generation of Th1 cells which secrete IFN-γ. These two pathways may play different roles in the pathogenesis of vasculitides. The antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are small vessel vasculitis associated with antibodies directly to myeloperoxidase (MPO-ANCA) such as eosinophilic granulo…
Un'appartenenza vulnerabile. Il sentimento della storia in Properzio
2021
The cultural heritage of mythical tales connected to real places in Rome is the core inspiration for the fourth book of Propertian elegies. But which features or attitudes lay the ground for the construction of collective memory? In this paper I will try to focus on how Propertius works on selection and removal of Roman history’s events and characters as early as in the first three books of Elegies: in the Propertian sense of history, the “belonging to” and the “distance from” the social frameworks of memory are re-examined by concepts as betrayal and vulnerability of thick relations tying together citizens, soldiers, friends.
Teacher-Student Relations in Two Tibetan Buddhist Groups in Helsinki
2017
AbstractBased on sixteen interviews with members of two Tibetan Buddhist groups in Helsinki, Finland, this article investigates how the role of the guru, power imbalance and power abuse are perceived by the students. This qualitative study aims at understanding what shape the reverence to the Vajrayana teacher takes in the egalitarian environment of a European country, where Buddhism is a relatively new phenomenon. The interviews show that while teachers are not losing importance, ways of choosing and paying respect to them changes. They also reveal confusion in defining abuse, and emphasis on personal agency and teachers’ accountability for avoiding it.
