Vocazione e resistenza. La "Commedia" riscritta per il teatro da Sanguineti, Luzi e Giudici

La tesi ha per oggetto i tre copioni danteschi di Edoardo Sanguineti, Mario Luzi e Giovanni Giudici, traspositori, rispettivamente, di Inferno, Purgatorio e Paradiso, nell’ambito del progetto di drammaturgia della Commedia ideato e commissionato dai Magazzini negli anni 1989-1991. L’analisi dei copioni si basa sulle teorie espresse da Genette in Palinsesti, e si sviluppa come lettura comparativa fra ipotesto (Commedia) e ipertesti (riscritture). Contestualmente, viene approfondito il tema della ricezione di Dante nel Novecento, specie nelle forme della traduzione in immagini, e fornita un'interpretazione − alla luce delle acquisizioni della critica dantesca novecentesca e della narratologia − della duplice natura del poema, materia prima oscillante tra vocazione e resistenza alla trasposizione drammatica.

Molekulardynamik-Simulationen zu Oberflächeneigenschaften von Siliziumdioxid-Schmelzen

Molekulardynamik-Simulationen zu OberflächeneigenschaftenvonSiliziumdioxid-Schmelzen In der vorliegenden Arbeit werdenMolekulardynamik-Computersimulationenzur Untersuchung der statischen und dynamischenOberflächeneigenschafteneiner Siliziumdioxid (SiO$_2$)-Schmelze durchgeführt.Als Modellpotential verwenden wirein in der Literatur als BKS-Potential bezeichnetesPaarpotential.Wir betrachten in dieser Arbeit zwei Systemgeometrien: zumeinenSysteme aus 432, 1536 und 4608 Atomen ohne periodischeRandbedingungen(Tropfen), zum anderen ein System aus 1152 Atomen mitperiodischen Randbedingungen in zwei Richtungen (dünnerFilm).Für beide Geometrien finden wir im Inneren der Systemekonstante Dichten.Direktan der Oberfläche halten sich ausschließlich Sauerstoffatomeauf.Die Strukturan der Oberfläche erscheint weniger ausgeprägt mit mehrDefekten, als im Inneren des Systems.Es erweist sich,daß viele Eigenschaften statischer Größen, die wir an derOberfläche im Vergleich zum Inneren finden, aufdas Vorhandensein von Zweierringen zurückzuführen sind.Bei der Betrachtung der dynamischen Größen finden wir eineerhöhteBeweglichkeit der Atome an der Oberfläche gegenüber demSysteminneren.

Bioluminescence imaging of angiogenesis in a murine orthotopic pancreatic cancer model

Angiogenesis is essential for physiological processes as well as for carcinogenesis. New approaches to cancer therapy include targeting angiogenesis. One target is VEGF-A and its receptor VEGFR2. In this study, we sought to investigate pancreatic cancer angiogenesis in a genetically modified VEGFR2-luc-KI mouse.

Danger assessment of a spring-gun device (muzzleloader) loaded only with black powder

We report a case involving a spring-gun device (muzzleloader) loaded solely with gunpowder, installed next to shoes to prevent the neighbors' puppy from removing them. The booby trap was triggered by the 15-year-old dog-owners son when he tried to put the shoes out of the reach of the puppy. The boy suffered second degree superficial burns located mainly at the dorsal side of the right hand and fingers. To estimate the danger of the used weapon, several tests were undertaken on soap blocks from different distances and with different loads of black powder. The particle density per mm and the depth of black powder tattooing in the soap was compared with the boy's injuries, and found conclusive with the gun-owners statement regarding the loading of the weapon. Furthermore, our experiments indicated that the gunpowder load involved was not able to inflict permanent damage, not even to the eyes, at the here estimated firing distance.

Allergen cross reactions: a problem greater than ever thought?

Cross reactions are an often observed phenomenon in patients with allergy. Sensitization against some allergens may cause reactions against other seemingly unrelated allergens. Today, cross reactions are being investigated on a per-case basis, analyzing blood serum specific IgE (sIgE) levels and clinical features of patients suffering from cross reactions. In this study, we evaluated the level of sIgE compared to patients' total IgE assuming epitope specificity is a consequence of sequence similarity.

Preclinical Evaluation of Radiolabeled DOTA-Derivatized Cyclic Minigastrin Analogs for Targeting Cholecystokinin Receptor Expressing Malignancies

Targeting of cholecystokinin receptor expressing malignancies such as medullary thyroid carcinoma is currently limited by low in vivo stability of radioligands. To increase the stability, we have developed and preclinically evaluated two cyclic 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA)-minigastrin analogs radiolabeled with (111)In and (68)Ga.

Increased phase synchronization during continuous face integration measured simultaneously with EEG and fMRI

Gamma zero-lag phase synchronization has been measured in the animal brain during visual binding. Human scalp EEG studies used a phase locking factor (trial-to-trial phase-shift consistency) or gamma amplitude to measure binding but did not analyze common-phase signals so far. This study introduces a method to identify networks oscillating with near zero-lag phase synchronization in human subjects.

Long-Term Outcome After Monosegmental L4/5 Stabilization for Degenerative Spondylolisthesis With the Dynesys Device

STUDY DESIGN:: retrospective analysis of prospectively collected clinical data. OBJECTIVE:: To assess the long-term outcome of patients with monosegmental L4/5 degenerative spondylolisthesis treated with the dynamic Dynesys device. SUMMARY OF BACKGROUND DATA:: The Dynesys® system has been used as a semirigid, lumbar dorsal pedicular stabilization device since 1994. Good short-term results have been reported, but little is known about the long-term outcome following treatment for degenerative spondylolisthesis at the L4/5 level. METHODS:: 39 consecutive patients with symptomatic degenerative lumbar spondylolisthesis at the L4/5 level were treated with bilateral decompression and Dynesys instrumentation. At a mean follow-up of 7.2 years (range 5.0-11.2▒y) they underwent clinical and radiographic evaluation and quality of life assessment. RESULTS:: At final follow-up back pain improved in 89% and leg pain improved in 86% of patients compared to preoperative status. 83% of patients reported global subjective improvement. 92% would undergo the surgery again. 8 patients (21%) required further surgery due to symptomatic adjacent segment disease (6 cases), late onset infection (1 case), and screw breakage (1 case). In 9 cases radiological progression of spondylolisthesis at the operated segment was found. 74% of operated segments showed limited flexion-extension range of less than 4°. Adjacent segment pathology, though without clinical correlation, was diagnosed at the L5/S1 (17.9%) and L3/4 (28.2%) segments. In 4 cases asymptomatic screw loosening was observed. CONCLUSION:: Monosegmental Dynesys instrumentation of degenerative spondylolisthesis at L4/5 shows good long-term results. The rate of secondary surgeries is comparable to other dorsal instrumentation devices. Residual range of motion in the stabilized segment is reduced, and the rate of radiological and symptomatic adjacent segment degeneration is low. Patient satisfaction is high. Dynesys stabilization of symptomatic L4/5 degenerative spondylolisthesis is a possible alternative to other stabilization devices.

Offline grammar-based recognition of handwritten sentences

This paper proposes a sequential coupling of a Hidden Markov Model (HMM) recognizer for offline handwritten English sentences with a probabilistic bottom-up chart parser using Stochastic Context-Free Grammars (SCFG) extracted from a text corpus. Based on extensive experiments, we conclude that syntax analysis helps to improve recognition rates significantly.
