Poesie di Chen Jingrong - Un piccolo omaggio
No full textChen Jingrong is a woman poet who has strongly influenced the poetry of the contemporary poet Duo Duo. Having lived from 1917 until 1989, her work spans through the whole XX century. The paper presents her work with a special attention on translation problems. It focuses on an analysis of her poetry on the basis of the “translation shift” described by Cosima Bruno. Differently from Bruno, the analysis is made not on two texts, A language and B language texts, but rather on three texts. In this case, the one in Chinese of the original version, the one in English, the language of the first translation, and the one in Italian, the language of the second translation by G. Tamburello

Robust identification for linear-in-the-parameters models
No full textIn this paper new robust nonlinear model construction algorithms for a large class of linear-in-the-parameters models are introduced to enhance model robustness, including three algorithms using combined A- or D-optimality or PRESS statistic (Predicted REsidual Sum of Squares) with regularised orthogonal least squares algorithm respectively. A common characteristic of these algorithms is that the inherent computation efficiency associated with the orthogonalisation scheme in orthogonal least squares or regularised orthogonal least squares has been extended such that the new algorithms are computationally efficient. A numerical example is included to demonstrate effectiveness of the algorithms. Copyright (C) 2003 IFAC
Modelling of Partial Discharge Behaviour in a Spherical Cavity within a Solid Dielectric Material as a Function of Temperature
No full textPartial discharge (PD) is an electrical discharge within a dielectric which does not bridge the electrodes. PD measurement has been widely used for assessing performance of insulation systems. Modelling of PD activity gives an insight of this activity and can provide important information for insulation diagnosis. In this paper, a finite element analysis (FEA) method has been used to build a model of PD activity within a spherical cavity in a dielectric material. The model has been used to study critical parameters and physical mechanisms affecting PD activity as a function of temperature. Critical parameters from the model have been identified through comparison between simulation and measurement results
Beneficial plant-microbe interactions in agriculture: reducing lettuce basal drop by application of rhizosphere competent Streptomyces
No full textYield losses caused by phytopathogens are major challenges to agriculture all over the world. Biological control based on plant-microbe interactions provides economically viable, environmentally sound, and socially responsible plant protection strategies. The ability of microorganisms to suppress plant pathogens and to interact with their host are fundamental prerequisites of microbial assisted plant protection. Two Streptomyces strains isolated from surface sterile crop roots, Streptomyces exfoliatus FT05W and Streptomyces cyaneus ZEA17I, showed up to 75% in vitro mycelial growth inhibition of Sclerotinia sclerotiorum, the causal agent of lettuce drop (Sardi et al. 1992; Chen et al. in press). We labeled them with the enhanced green fluorescent protein (EGFP) marker to investigate Streptomyces’ ability to colonize the lettuce root system using confocal laser scanning microscopy (CLSM) (Bonaldi et al. 2015; Erlacher et al. 2015). The well-colonized lettuce seedlings by both strains showed Streptomyces’ capability to interact with the host from early stages of seed germination and root development. We also observed colonization by EGFP-labeled Streptomyces on two-week-old roots. Additionally, we quantified S. exfoliatus FT05W and S. cyaneus ZEA17I viability and persistence in the rhizosphere and surface sterilized lettuce root tissues. After six weeks of plant growth, we recovered 2 x 104 CFU/g dry weight (DW) from the rhizosphere and 2 x 105 CFU/g DW from the inner root tissues. Moreover, we studied the biological activity of the two strains against S. sclerotiorum in vivo. When they were applied to S. sclerotiorum inoculated substrate in growth chamber, S. exfoliatus FT05W and S. cyaneus ZEA17I reduced disease incidence significantly by 40% and 50%, respectively, compared to the control (P < 0.05). Differently, under field conditions, S. exfoliatus FT05W reduced disease incidence by 54% (P = 0.12), but we did not observe protection of lettuce plants against S. sclerotiorum by S. cyaneus ZEA17I. Further studies on the complex host-pathogen-antagonist interactions will provide additional knowledge to understand the modes of Streptomyces acting as promising biological control agents
A Rosary of Rubies: The Chronicle of the Gur-rigs mDo-chen Tradition from South-Western Tibet
No full textThe mDo-chen bKa’-brgyud-pa school represents a little known Buddhist tradition from Mang-yul Gung-thang in south-western Tibet. It goes back to a Buddhist yogin known as Ma-bdun-pa or Ma-bdun ras-chen (12th/13th c.) and was later mainly spread by members of the Gur family. Although belonging to the “Upper ’Brug” (stod ’brug) branch of the ’Brug-pa bKa’-brgyud-pa school, the mDo-chen tradition has always been deeply infused with the “spoken teachings” (bka’ ma) and “treasure teachings” (gter ma) of the rNying-ma-pa school, and the cult of the “Seven Ma-mo Sisters” (ma mo mched bdun) was particularly practised and transmitted by its members. This book presents a critical edition, an annotated translation and a photographic reproduction of a manuscript copy of a rare chronicle of the Gur-rigs mDo-chen tradition written by Brag-dkar rta-so sPrul-sku Chos-kyi dbang-phyug (1775–1837). The text provides us with an overview of the tradition’s development mainly through biographical accounts but also through prophecies, prayers and praises for individual masters. The study concludes with two appendices based on the mDo chen bka’ brgyud gser ’phreng, a lineage history composed in the 15th century, and the “records of teachings received” (thob yig) of three important members of the Gur family, thus allowing us to gain an insight into the transmissions of the mDo-chen bKa’-brgyud-pa school and the interactions of its representatives with other important Buddhist teachers up to the 18th century. The present work is a further outcome of the author’s investigations into the cultural and religious traditions of south-western Tibet and the neighbouring Himalayan valleys
Measurement of Partial Discharge Activities within Two Artificial Spherical Voids in an Epoxy Resin
No full textMeasurement of partial discharge activities within insulation systems has been extensively performed. It has been widely used in the performance assessment of an insulation system and for insulation diagnostics. Since a void cavity is one of the potential sources of PD activity in insulation which may cause degradation and breakdown, it is very important to study PD events associated with void cavities solid dielectric insulation. In this work, the measurement of PD activity has been performed on test samples consisting of two spherical voids within an epoxy resin. Two voids of same and different sizes are positioned close to each other and in parallel with the direction of the applied field within the epoxy. Through comparison of the experiment data for PD events within a single void in the epoxy, single and multiple discharge sources from different voids can be clearly distinguished
