Phylogeny inferred from codon usage pattern in 31 organisms
No full textWe employed the Codonusage database to analyze the codon usage pattern in 31 organisms from all the main biological taxa. We tested the similarity in codon usage pattern between each organism and all the others by the Pearson linear correlation coefficient. The 465 values obtained were located in a 31 x 31 triangular matrix from which a correlation distance matrix was calculated. An evolutionary dendrogram was then constructed from these distances. The results showed a fair correlation between codon usage patterns and phylogenetic relationships, at least for organisms which diverged in rather recent times (end of Jurassic--beginning of Cretaceous)
Dwelling in contradictions : Deep maps and the memories of Jews from Libya
No full textThe article deals with performances of memories and identities by and about Jews from the Middle East and North Africa region, with a focus on Jews of Libyan descent. It acknowledges the complexity that intrinsically characterizes these sources in terms of the heterogeneity of their contents, but also the political implications inherent to their transmission and communication. What is needed, however, is to make this complexity readable, and to make it readable, the author suggests making it visible. To achieve this goal, the author proposes adopting a new research approach which takes inspiration from the field of digital humanities, to assist in thinking spatially and visually about the performances of memories and identities. This can bring about a kind of methodological reconciliation between the researcher, the complexity of the data, the necessity to transform them into accurate research results and the responsibility to effectively communicate them to the larger public.Cet article traite des performances mémorielles et identitaire par et sur les Juifs du Moyen-Orient et de l’Afrique du Nord, en mettant l’accent particulièrement sur les Juifs d’origine libyenne. Il présente la complexité qui caractérise intrinsèquement ces sources en terme d’hétérogénéité de leurs contenus, mais aussi en ce qui concerne les implications politiques inhérentes à leur transmission et à leur communication. Cependant, il est nécessaire de rendre cette complexité lisible et, pour la rendre lisible, l’auteur suggère de la rendre visible. Pour atteindre cet objectif, l’auteur propose d’adopter une nouvelle approche de recherche qui s’inspire du domaine des humanités numériques pour aider à penser spatialement et visuellement les performances des mémoires et des identités. Cela peut entraîner une sorte de rapprochement méthodologique entre le chercheur, la complexité des données, la nécessité de les transformer en résultats de recherche précis et la responsabilité de les communiquer efficacement au grand public
Evasivas. Carlos Piera y la retórica del poema
No full textThis article proposes "evasiveness" as a concept that allows us to develop a relationship between the theoretical essays and the poetry of Carlos Piera. To this end, we follow the traces left by two of the possibilities of a tropology of evasion, i.e. ellipsis and contradiction, taking into consideration the influence of Baltasar Gracián in Piera's work. These figures also refer to the rhetoric of temporality of Paul de Man, an author who receives a significant treatment at different moments of Piera's essays. From his reading of de Man's thesis, the rhetorical theory of the poem is based on what the present article conceptually characterises as a way of avoiding the subject.El presente artículo propone la "evasividad" como concepto que permite establecer una relación complementaria entre los ensayos teóricos y la escritura poética de Carlos Piera. A tal fin se siguen las diversas huellas que dejan en su obra dos posibilidades concretas de una tropología de la evasión, elipsis y contradicción, tomando en consideración la influencia barroca de Baltasar Gracián. Estas figuras remiten igualmente a la retórica de la temporalidad de Paul de Man, autor que recibe un tratamiento señalado en diferentes momentos de la obra ensayística de Piera. Desde su lectura de las tesis demanianas, la teoría retórica del poema se fundamenta en lo que este trabajo caracteriza conceptualmente como evasivas al sujeto
Metafore tra concettualizzazione e traduzione nel latino cristiano delle origini (Prima Lettera di Clemente)
No full textIl presente lavoro esamina due tipi di concettualizzazione metaforica documentati nella Prima Lettera ai Corinzi attribuita a Clemente di Roma, il primo testo cristiano scritto in greco a Roma alla fine del I secolo e tradotto in latino presumibilmente entro la metà del II secolo. Nello specifico, l'analisi si concentra sulle metafore agonistiche e militari per mostrare come le scelte linguistiche dell'autore e del traduttore contribuiscano alla formazione del lessico cristiano nelle due lingue, spesso in modo originale. Queste metafore mescolano tratti linguistici e culturali ebraici, ellenistici e romani, in una sintesi che diventa una caratteristica del linguaggio dei cristiani.This paper examines two kinds of metaphorical conceptualization documented in the First Epistle to the Corinthians attributed to Clement of Rome, the first christian text written in Greek in Rome at the end of the 1st century and translated into Latin presumably by the middle of the 2nd century.
Specifically, the analysis focuses on agonistic and military metaphors to show how the linguistic choices of the author and the translator contribute to the formation of the christian lexicon in the two languages, often in an original way. These metaphors mix Jewish, Hellenistic and Roman linguistic and cultural traits, in a synthesis that becomes a feature of the language of christians
How to Measure the Green Façade Sustainability? A Proposal of a Technical Standard
No full textAbstractDifferent guidelines drive EU countries to use greening systems – green roofs and green façades - as a sustainable strategy to maximize environmental buildings performance. While technical standards concerning green roofs are available, standards concerning green façades and particularly Living Wall Systems (LWSs) still missing. The paper deals with a research carried out in order to develop a proposal of a technical standard to be adopted as method and tool to measure the performances of green façades and LWSs according to a sustainable approach. The proposal was implemented in consistency to an Italian standard (UNI 11235:2015). The UNI 11235 contains the instructions for designing, building up, monitoring and maintaining the green roofs. Although the standard is not international some basic information may be applied at global scale and most importantly at green façades. The study was focused to setting-up a proper number of requirements to be met in: designing a LWS; defining guidelines for construction stage; monitoring the performance. Requirements and guidelines were set up according to a wide study on international references and thanks to an industrial research project where the authors were involved. Monitoring carried out on chamber tests and on-site was enabled to getting comprehensive data helpful for assessing environmental properties of LWSs and on the whole to characterizing some requirements to be used in the standard
Microevolution in Ferrara: isonymy 1890-1990
No full textThe distribution of surnames in the population of the town of Ferrara, as it existed in the memory banks of the Municipality Computer in June 1990, was studied by sex, age and place of birth of residents. Random isonymy was studied separately in persons born before 1901, and in persons born in the nine decades thereafter, ending with the period 1981-90. Isonymy was higher in the older age groups studied. Also other indicators of the abundance of surnames in the distribution, the common ecological indexes derived from entropy, were calculated and compared between age groups. It was found that redundancy, as isonymy, is larger in older age classes than in younger classes. Surname effective number was defined as the inverse of isonymy corrected for sample size, and it was observed that it is practically identical with Fisher's alpha. It was then possible to separate random isonymy into two components, so that for sample size N its formulation becomes I(r) = 1/alpha + 1/N It was found that in Ferrara alpha increased significantly in time, indicating enrichment of surnames in the population in the century 1890-1990
Seismic Response of a Strategic Building in Catania (Italy) by 2-D FEM Analysis
No full textAbstractIn the last 900 years, the east coast of Sicily has been struck by several disastrous earthquakes. The earthquakes occurred in 1169, 1542, 1693, 1818, 1908 and more recently in 1990, with estimated magnitudes, ranging from less than 5.0 to greater than 7.0, testify the high level of hazard in this area. Many towns were destroyed during the above-mentioned earthquakes. The high level of seismicity that affects the area, together with the considerable high density of inhabitants living in its urban area, contribute to classify it as one of the area having the highest seismic risk in Italy. It is also not negligible the high potential damage to which its historic-architectural patrimony could undergo even at moderate magnitudes. Many researches show that the site seismic response is strongly influenced by stratigraphic and topographic features. Site response can reduce or amplify the earthquake induced ground motion. In this study seismic response of strategic building located in Catania has been done, and main results are presented
Feasibility study of biomass hybrid micro-plants for mini-grid based electricity services in rural communities in Ghana
No full textElectricity access is key in driving socio economic development. Since Ghana initiated its National Electrification Scheme (NES) 20 years ago, access has risen to 72%, with over 88,000 communities yet to be electrified.
From 2006 to 2008, the Multifunctional Platform (MFP) programme provided mechanical energy services based on diesel engines in 38 off-grid communities; yet these communities are rich in agricultural residues. International experience has shown that decentralised power generation by biomass gasification systems is cost competitive for remote villages with low load demand, and has the lowest environmental impact as compared to other conversion technologies.
Additionally, the Ghanaian Renewable Energy Law sets forth the possibility for distribution utilities to benefit from renewable energy obligations in investments conducted in rural areas. This study was commissioned to investigate the prospects of electricity service provision based on biomass gasification technology. To this end, the feasibility of using agricultural residues to run a 24 hour mini-grid electricity service has been characterised in five MFP communities in Ghana (Brong Ahafo and Northern regions). The institutions involved in this study, TEC-KNUST, KITE and IS.UPC are partners in the diffusion of sustainable energy solutions, as a key action to eradicate energy poverty in the region.Peer ReviewedPreprin
