No exception to the rule: Candidatus Portiera aleyrodidarum cell wall revisited
2014
International audience; Many insect endosymbionts described so far are gram-negative bacteria. Primary endosymbionts are obligatory bacteria usually harboured by insects inside vacuoles in specialized cells called bacteriocytes. This combination produces a typical three-membrane system with one membrane derived from the insect vacuole and the other two from the bacterial gram-negative cell envelope, composed by the cell wall (the outer membrane plus the periplasmic space) and the plasma membrane (the inner membrane). For the last 21 years, the primary endosymbiont of whiteflies 'Candidatus Portiera aleyrodidarum' was considered an exception to this rule. Previous works stated that only two …
El macro-modelat de la costa carbonàtica de Victòria (Austràlia): paral.lelismes i diferències amb les cales baleàriques
2019
Les cales són penetracions marines, preferentment a un litoral carbonatat de caràcter tabular, arran de la inundació eustàtica d’un antic curs fluvial en la morfogènesi de les quals, de més a més del paper de la fracturació distensiva i la carstificació, també hi participen els mecanismes de col·lapse i la dinàmica litoral així com les variacions glacio-eustàtiques del nivell marí, especialment durant el Quaternari. El present treball aborda la tipologia i característiques dels elements del macro-modelat de la costa rocosa de Victòria (sud d’Austràlia) i les compara amb els antecedents i el coneixement obtingut en l’estudi de les cales de la Mediterrància occidental, principalment les de le…
"Frater, ave atque vale" (Catull. 101.10): fortuna literaria de una fórmula epigráfica
2011
Trabajo realizado dentro del Grupo de Investigación «Tradiciones Clásicas» de la UPV/EHU (GIU-07-26) [ES] En este artículo ofrecemos un panorama con algunos de los autores modernos –Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead y Anne Carson– que han dado nueva vida al motivo del saludo directo al difunto, a partir del carmen 101 de Catulo, cuyo verso 10 sigue gozando de un especial éxito, apoyado por la efectiva simplicidad de su saludo emotivo al hermano y de su forma, asequible y reconocible aun cuando el conocimiento de la lengua latina sea menor. [EN] In this article we offer an overview of some of the modern authors (specially Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead,…

Small but Powerful, the Primary Endosymbiont of Moss Bugs, Candidatus Evansia muelleri, Holds a Reduced Genome with Large Biosynthetic Capabilities
2014
International audience; Moss bugs (Coleorrhyncha: Peloridiidae) are members of the order Hemiptera, and like many hemipterans, they have symbiotic associations with intracellular bacteria to fulfill nutritional requirements resulting from their unbalanced diet. The primary endosymbiont of the moss bugs, Candidatus Evansia muelleri, is phylogenetically related to Candidatus Carsonella ruddii and Candidatus Portiera aleyrodidarum, primary endosymbionts of psyllids and whiteflies, respectively. In this work, we report the genome of Candidatus Evansia muelleri Xc1 from Xenophyes cascus, which is the only obligate endosymbiont present in the association. This endosymbiont possesses an extremely …
Potential demand and cost-benefit analysis of electric cars
2004
In this study an analysis of electric family car performances is carried out. In particular, the aim of this research is to appraise the possibility of introducing electric cars in urban mobility and the evaluation of its economic feasibility. First of all, we determined the potential electric car demand, which was forecasted using a stated preference (SP) analysis. The survey was carried out at the University of Palermo considering a particular target of consumer: ‘the hybrid household’. A logit demand model was calibrated using the SP technique to model the choice between the electric car and the conventional one. In the second part of the work, the economic feasibility of the electric ca…
The frontier between cell and organelle: genome analysis of Candidatus Carsonella ruddii
2007
Background Bacterial symbioses are widespread among insects. The early establishment of such symbiotic associations has probably been one of the key factors for the evolutionary success of insects, since it may have allowed access to novel ecological niches and to new imbalanced food resources, such as plant sap or blood. Several genomes of bacterial endosymbionts of different insect species have been recently sequenced, and their biology has been extensively studied. Recently, the complete genome sequence of Candidatus Carsonella ruddii, considered the primary endosymbiont of the psyllid Pachpsylla venusta, has been published. This genome consists of a circular chromosome of 159,662 bp and…
A contrastive Analysis of the first Canto of Dante’s Inferno: an Examination of the Translations of Seamus Heaney and Ciaran Carson
2008
The article offers a comparative analysis of two English translations of the first Canto of Dante's Inferno: both produced by Irish authors, the two greatly differ. Specific translation strategies are examined in relation to the authors' distinctive poetic styles.
From cars to bikes – the feasibility and effect of using e-bikes, longtail bikes and traditional bikes for transportation among parents of children a…
2017
Abstract Background The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not fulfilled by e-bikes or traditional bikes, hence increased knowledge regarding their feasibility should be obtained. No previous studies have investigated whether providing an e-bike or a longtail bike over an extended period in a sample of parents of toddlers influence objectively assessed a…
Mobility scenarios in the Valley of the Temples
2015
The valley of the Temples in Agrigento is one the most known wonders of the ancient Greek time to be still standing is South Italy. Chosen as an emblematic location in the center of the island, it is the exemplary site used to assess the potential for electric mobility in terms of energy and environmental benefits of electricity over standard fuels. Such an assessment is performed by means of a life-cycle approach, including the use of the Life Cycle Assessment methodology, the use of the standard ILCD-PEF indicators and the development of a parametric analysis investigating the impact of different electricity penetration levels in the local transports system. The results identify relevant …
