No full textCharacterisation of ten commercial sorghum genotypes grown under water-limited conditions for bioenergy production in Mediterranean environment
Get PDFThe evaluation of commercial hybrids under limited water availability is of primary importance to assess Sorghum bicolor (Moench) as potential multipurpose bioenergy crop in Mediterranean drought prone environments. Ten genotypes were grown during three growing seasons (2010, 2011 and 2012) in open field trials and in pot experiments (2014). Phenological traits, biomass production, fibre content and biomass chemical composition were measured under irrigated and rainfed conditions. Differences in biomass production among the ten genotypes varied across years. In a three-year experiment significant differences were found among the ten genotypes in terms of duration of vegetative growth (P<0.05) and aboveground dry biomass production (P<0.1) in response to irrigated and rainfed conditions. Among the ten genotypes analysed, the hybrid ABF306 stands for its performance in terms of biomass production and chemical composition. In fact, it showed the lowest biomass yield reduction when grown under rainfed conditions, the highest drought tolerance index (=0.9), a °Brix value comparable to that of sweet sorghum genotypes (8.8 °Brix under rainfed conditions), lignin content that was not statistically influenced by water availability, and a lignin cellulose ratio (0.087) favourable for biogas production. The shoot transpiration efficiency and the total transpiration efficiency recorded at high (Exp1) and low (Exp2) vapour pressure deficit were comparable, and sometimes higher, to that of commercial sorghum hybrids. All these characteristics make ABF306 a suitable candidate for bioenergy production in Mediterranean drought prone environments

Selected letters of Alessandra Strozzi
No full textThe letters of Alessandra Strozzi provide a vivid and spirited portrayal of life in fifteenth-century Florence. Among the richest autobiographical materials to survive from the Italian Renaissance, the letters reveal a woman who fought stubbornly to preserve her family's property and position in adverse circumstances, and who was an acute observer of Medicean society. Her letters speak of political and social status, of the concept of honor, and of the harshness of life, including the plague and the loss of children. They are also a guide to Alessandra's inner life over a period of twenty-three years, revealing the pain and sorrow, and, more rarely, the joy and triumph, with which she responded to the events unfolding around her.This edition includes translations, in full or in part, of 35 of the 73 extant letters. The selections carry forward the story of Alessandra's life and illustrate the range of attitudes, concerns, and activities which were characteristic of their author
Challenging the author: Gavin Douglas's Eneados
No full textGavin Douglas’s Eneados, a translation into the “Scottis” tongue of Virgil’s Aeneid, completed in 1513 and first published in London in 1553, presents, as well as the translation of the additional thirteenth book by Maphaeus Vegius, original prologues and marginal notes to the text, rubrics and articulate conclusive material. The present paper analyses this complex paratext as evidence of Douglas’s almost philological attention to the original and his preoccupation with a faithful reproduction; it is also suggested that the models for his organization of the commentary might be both medieval (i.e., manuscripts such as Petrarch’s Virgilius Ambrosianus) and early modern, as in the case of editions of classical works: the most apt example being Jodocus Badius Ascensius’ edition of the Aeneid, printed in 1501. The Eneados thus stands on the threshold between manuscript and print, and might have indicated new possibilities of use of the printing medium in Scotland, and of the value of the translation of a classical text, had history not intervened with the Scottish defeat at Flodden Fields in 1513, which put a temporary stop both to the circulation of the Eneados and to the development of Scottish printing
Nicetas Nicaenus, De azymis
No full textThe RAP online repertorium offers the first comprehensive catalogue of polemical literature related to the schism between the Roman Catholic and Orthodox Churches from the 9th to the 16th century and can be described as an ideal continuation of the *Clavis Patrum*.
Each entry identifies the work (often unpublished or newly discovered in manuscript catalogs), lists its various titles (since medieval texts often lack stable titles), provides incipit and explicit (with possible variations), and examines the manuscript tradition and foliation (by reviewing catalogs or manuscripts, verifying dates, folios, etc.). It also includes relevant bibliography (critical editions and studies), identifies the author (using prosopographical studies, dictionaries, repertories, sigillography, etc.), and provides essential biographical details. Each work is classified by literary genre (e.g., treatise, dialogue), the corresponding Byzantine term, and the main polemical themes (e.g., Filioque, Azymes, Purgatory), and is assigned a unique RAP identification number.

QRS complex configurations in 12-lead electrocardiograms of dogs with monomorphic ventricular tachycardia or complete bundle branch block
Get PDFIntroduction: The differentiation between ventricular tachycardias (VT) and
supraventricular tachycardias (SVT) with bundle branch block (BBB) is clinically
challenging. The aim of the study was to define by the 12-lead-electrocardiogram
the QRS complex morphology in monomorphic VT (MVT) and in BBB.
Methods: Twelve-lead-electrocardiograms were blindly retrospectively
analyzed and categorized in four groups: sinus rhythm with left bundle branch
block (SR-LBBB), sinus rhythm with right bundle branch block (SR-RBBB), MVT
with RBBB configuration (MVT-RBBB), MVT with LBBB configuration (MVTLBBB).
Measurements were not normally distributed, and they were normalized
by Box–Cox transformation. Repeated-measures linear mixed-effects models
were constructed according to the 3 measurements performed.
Results: A total of 103 12-lead-electrocardiograms were retrospectively
analyzed: 18 SR-RBBB, 18 SR-LBBB, 33 MVT-RBBB, 34 MVT-LBBB. Limb leads
concordance was found in 100% of SR-RBBB, 100% of SR-LBBB, 54.5% of
MVT-RBBB, 70.6% of MVT-LBBB. Precordial leads discordance was present in
100% of SR-RBBB, 100% of SR-LBBB, 78.8% of MVT-RBBB, 88.2% of MVT-LBBB.
The transition point was located at V1-V2 in 100% of SR-RBBB, 100% of SRLBBB,
50.5% of MVT-RBBB and 71.5% of MVT-LBBB. Positive V1 with M shape
morphology was detected in 100% of SR-RBBB and 12% of MVT-RBBB. The
mean electrical axis on the frontal plane was -108.15° (−118.29 / −101.52) in
RSSR-RBBB, 75.42° (71.78–80.46) in RSSR -LBBB, -93.46° (−102.75/−78.49) in
MVT-RBBB and 82.27° (76.85–88.95) in MVT-LBBB.
Discussion: In case of inability to identify signs of atrioventricular dissociation,
the presence of standard limb leads discordance, precordial leads concordance
or discordance with transition point other than V1-V2, left limb leads and left
precordial leads discordance, aVR and V1 discordance and absence of M shape
configuration of the QRS complex in lead V1 is likely to be MVT
Bacillus subtilis mutS mutL operon: identification, nucleotide sequence and mutagenesis
No full textThe Bacillus subtilis mutS and mutL genes, involved in the DNA mismatch repair system, have been cloned and characterized. From sequence analysis the two genes appear to be organized in a single operon, located immediately downstream of the cotE gene (approximately 150 degrees on the genetic map). The deduced MutS protein is 49% identical to HexA and MutL is 46% identical to HexB of Streptococcus pneumoniae. Deletion of both mutS and mutL resulted in an increase in the frequency of spontaneous mutations and abolished the marker effect observed in transformation. The expression of the mut operon was studied with the use of a mutSL-lacZ transcriptional fusion. An increase in expression was observed during late exponential growth
