The originality of Metastasio's Ciro riconosciuto between a Meropian and a Cyrian current.
Get PDFopenLa sottolineatura che questa tesi vorrebbe dare all’opera metastasiana, fitta solitamente e meritatamente di commenti sulla poetica, è fondata piuttosto su un confronto intertestuale, che metta in luce l’originalità del Ciro riconosciuto.
Il focus su questo dramma in particolare avviene dapprima con l’analisi del mito di Merope dal Cinquecento a Metastasio, a partire dai titoli delle varie opere, dalle modalità del riconoscimento e dai nomi dei personaggi. Da questo confronto infatti si nota come dai precedenti a Metastasio emergano due indirizzi, che ho chiamato filone ‘meropeo’ e ‘ciriano’, sapientemente fusi o confluiti nel Ciro riconosciuto. Si cerca di spiegare come l’attenzione ai personaggi della madre e del figlio in un modo così particolare sia anche probabilmente legata alla vicenda personale dell’imperatrice Elisabetta, dedicataria del dramma.
Da un’intertestualità esterna all’autore si analizza poi l’apporto del Ciro all’interno della carriera poetica metastasiana, determinando come sia nuovamente personaggio estremamente maturo, originale e chiave, quasi svolta sintetica di una prima stagione.
Si è cercato di mantenere un’attenzione ai testi, spesso poco protagonisti della critica metastasiana, con la speranza che non se ne perda la ricchezza e si ampli sempre più l’interesse per le singole opere. Infine soprattutto riguardo il confronto con Giulio Cesare Sorrentino mi sembra aperto uno spiraglio di ricerca.The emphasis that this thesis would like to give to the Metastasian work, usually and deservedly full of comments on poetics, is rather based on an intertextual comparison, which highlights the originality of the Ciro riconosciuto. The focus on this drama in particular occurs first with the analysis of the myth of Merope from the sixteenth century to Metastasio, starting with the titles of the various works, the methods of recognition and the names of the characters. In fact, from this comparison it is noted that from the precedents to Metastasio two directions emerge, which I have called the 'Meropeus' and 'Cirian' vein, wisely merged or merged into Ciro riconosciuto. I tried to explain how the attention to the characters of the mother and child in such a particular way is also probably linked to the personal story of the Empress Elizabeth, dedicatee of the drama.
From an intertextuality external to the author, the contribution of Cyrus to the Metastasian poetic career is then analyzed, determining how he is once again an extremely mature, original and key character, almost a synthetic turning point of a first season.
I tried to keep an attention to the texts, often not very protagonists of the Metastasian criticism, with the hope that their richness will not be lost and the interest in the individual works will grow more and more. Finally, especially with regard to the comparison with Giulio Cesare Sorrentino, a window of research seems open to me
Fetoendoscopy, The author replies
No full textThe precision lent by Akgu ̈ r and Olguner to our experimental
model of gastroschisis using fetoendoscopy is
altogether welcome. The distinctions they make are
good ones semantically.
They are correct when they say that amniotic fluid
(AF)exchange is different from amnioinfusion. Both
methods are used to lower the intraamniotic meconium
concentration. AF exchange can be used in all cases
(with or without oligohydramnios), and we think that it
will probably prove to be superior to amnioinfusion
alone, which is already used in clinical cases with severe
oligohydramnios [1, 4, 5].
In our study, we implanted a subcutaneous port so
as to minimize repetitive utero puncture and then be
able to perform the AF exchange several times, far more
often than actually acceptable in clinical practice.
However, tolerance was not as good as we had hoped
[2], even in ewes. The induction of fetal diuresis by furosemide
as proposed by Hakgu ̈ der et al. seems to be a
promising alternative therapy [3]
El Indigena En Iberoamerica Segun Ciro Alegria [The Indigenous in Latin America According to Ciro Alegria]
No full textCiro Alegria trata los problemas de los indios en Sur America y por esto sus novelas estan clasificadas como indianistas. El autor conocia a fondo los problemas de los indios ya que nacit en la sierra peruana. Alegria solo escribit cuatro libros: La Serpiente de Oro, Los Perros Hambrientos, El Mundo es Ancho y Ajeno y Duelo de Caballeros. Estos cuatro libros son suficientes para ponerlo en lo mas alto de los escritores de hispano-america. [Ciro Alegria deals with the problems of the Indians in South America and for this reason his novels are classified as Indianist. The author knew in depth the problems of the Indians since he was born in the Peruvian mountains. Alegria only wrote four books: The Golden Serpent, The Hungry Dogs, The World is Wide and Foreign and Duel of Knights. These four books are enough to put him at the top of Latin American writers.
Sintetizacion y caracterizacion estructurales de composicion quimica y optica de oxidos luminiscentes
No full textInfluencia en la incorporación de Li⁺ en películas delgadas de Y₂O₃ : Erᶾ⁺
No full textEn este trabajo se presentan los resultados obtenidos de la síntesis y caracterización de películas delgadas de Óxido de Itrio; se impurificaron con Erbio y codoparon con iones de Litio. Las películas se depositaron mediante la técnica de roció pirolítico ultrasónico. Los depósitos se realizaron sobre obleas de silicio (111). Las características de emisión luminiscente de estas películas están relacionadas con transiciones entre niveles electrónicos de energía del Er3+. Se mostró un aumento en la intensidad de emisión luminiscente de 4 a 5 veces con la adición de 2 % de Li+. Los espectros de emisión fueron obtenidos excitando con una longitud de onda de 207nm. El espesor de las películas fue de 100nm aproximadamente. La morfología superficial se determinó mediante microscopia electrónica de barrido, donde se observa la formación de aglomerados cúbicos con dimensiones de hasta 33nm. La composición elemental se obtuvo mediante espectroscopia por dispersión de energía; se muestra un enriquecimiento de Oxigeno y una disminución del Itrio cuando las concentraciones de Li+ y las temperaturas son altas. La estructura policristalina de las películas fue determinada por difracción de rayos X, muestra una fase cubica pura del ´ Oxido de Itrio. Para concentraciones mayores al 1 % de iones de Litio se reduce la intensidad de los picos de difracción y además se observa un desplazamiento del pico de difracción principal (222) hacia ángulos grandes. En los espectros de infrarrojo de las películas se observó la formación de compuestos de Litio
Preparación a bajas temperaturas de SiO2, mediante procesos de plasma, usando como materiales fuente SiCl4 y O2
No full textSe han preparado películas de dióxido de silicio mediante las técnicas de depósito químico en fase de vapor asistido por plasma y asistido por plasma remoto (PECVD y RPECVD, respectivamente). En ambos casos se usaron como materiales fuente SiCl4 y 02. En el caso de RPECVD se usaron como gases diluyentes Ar para el O2 e hidrógeno para el SiCl4. Mientras que en las muestras preparadas por PECVD no se usó ningún gas diluyente. La calidad estructural de las películas depositadas se analizó mediante mediciones de espectroscopia en el infrarrojo, elipsometría, espectroscopia electrónica Auger y tasa de ataque químico. La integridad eléctrica de las muestras se analizó mediante mediciones de corriente - voltaje y capacitancia-voltaje, al preparar estructuras MOS. Se demuestra que, mediante PECVD es posible obtener óxidos de buena calidad a temperaturas de subestrato de 200 oC, siempre que se usen tasas de flujos de gases bajas, que resulten en tasas de depósito bajas. óxidos de buena calidad se obtienen a temperaturas de subestrato en el intervalo de 100 a 200 °C mediante RPECVD, también con tasas de depósito bajas. Las características estructurales y eléctricas de los óxidos preparados son comparables a aquellas reportadas en cuyas preparaciones se usan altas tasas de flujos de gases diluyentes y/o temperaturas de subestrato mayores. Los óxidos preparados en el presente caso tienen las propiedades estructurales y eléctricas que hacen adecuada su aplicación en la tecnología de estructuras electrónicas en película delgada basadas en a- Si:pp.No contien
Transumbilical open laparoscopy: a simple method of avoiding complications in pediatric surgery
No full textThe author reports his experience with a new procedure, transumbilical open laparoscopy (TUOL), to obtain the pneumoperitoneum in children operated upon laparoscopically. TUOL was designed to avoid complications related to closed introduction of the first trocar, and consists in the visually-guided introduction of the first trocar transumbilically without any need for a pursestring suture, with an operative time of about 1 min. The author recommends TUOL as it is easier, less expensive, and less time-consuming compared to other techniques
Síntesis y caracterización de polvos nanométricos de óxido de itrio dopados con disprosio por el método del polyol
No full textUna praelectio omerica di Niccolò Leonico Tomeo (BAV, Ross. 997)
No full textThe Rossianus 997, a manuscript now preserved in the Vatican Library, transmits part of the correspondence of the Venetian humanist Niccolò Leonico Tomeo (1456-1531). In the last few folios of this slender codex, survives a still unpublished text, an inaugural lecture opening a university-course on the Iliad, dated 1486. The name of the author is unknown but thanks to several internal clues we are now able to attribute this text to the same Niccolò Leonico Tomeo, thus adding a new piece of evidence concerning his early years in Padua and the succession of the first teachers of Greek in that city. The new attribution lead to the discovery of a manuscript of the Iliad annotated by Tomeo, possibly connected to his lectures on the text. Following a detailed study of the structure of the text and a full account of the sources exploited by the author, we offer an editio princeps of the lecture accompanied by a commentary
One trocar appendectomy in pediatric surgery
No full textLaparoscopic appendectomy is a safe alternative
to open appendectomy to treat appendicitis. The author reports
his experience in performing laparoscopic appendectomy
with the use of only one trocar in pediatric patients.
Between 1 January 1994 and 30 October 1995 at the Department
of General and Pediatric Surgery, Division of Pediatric
Surgery of the ‘‘Federico II’’ University of Naples,
we performed 51 laparoscopic appendectomies. Patient age
varied from 4 to 16 years with a mean age of 7 years. In the
last 25 patients of our series we performed the one-trocar
appendectomy, positioning only one trocar infraumbilically
with the use of a 10-mm operative telescope. The appendix
is identified, dissected when necessary, grasped laparoscopically
with a 450-mm operative atraumatic instrument
introduced through the operative channel of the laparoscope,
and then exteriorized through the umbilical cannula.
The appendectomy was performed using traditional method
outside the abdominal cavity. We had no intra- or perioperative
mortality or morbidity. The mean overall hospitalization
time was 2 days (1–4 days). At a maximal follow-up
of 20 months the children have no clinical problems nor any
visible scar related to the laparoscopic appendectomy. In
conclusion, the author considers the one-trocar appendectomy
an appropriate alternative procedure to other techniques
of laparoscopic appendectomy
