    Al publicar María Teresa León La Historia tiene la palabra (1944), deja constancia de un objetivo puntual: la justificación de la política cultural de la República española durante la guerra civil, basada en la Protección del Tesoro Artístico en la que ella misma participó. Narra, pues, un episodio de la Historia, siendo a la par testigo y actor del mismo, ve su índole modificada por su inclusión dentro de una temporalidad más amplia, que apela a la potencia de la imaginación. Se halla pues integrado dentro de un estuche poético que lo protege y exhibe a la vez, con lo cual el relato ficticio adquiere una función superior, por ser el único capaz de revelar el secreto de la verdadera historia. When María Teresa león published La Historia tiene la palabra (1944), her professed goal was to justify the cultural policy of the Spanish Republic in times of civil war through the Preservation of the Artistic Patrimony she had taken an active part in. It was thus both as ana gent and a witness that she wrote about that episode in Spanish history, yet the inclusión in a more extensive temporality, that appeals to the power of imagination, transforms the nature if the Basic event, related in obejective detalil, Then the event becomes integrated into a poetic box, that both protects and shows it, and the fictional story, that is load with an high function, seems to be the Orly one capable to reveals the secreto f the true History

    Personal Jurisdiction over Retailers and Regional Distributors in Products Liability Litigation: Sufficiency of a Single Contact

    This Comment examines the United States Supreme Court\u27s opinion in World-Wide Volkswagen Corp. v. Woodson and argues that the Court attempted to resolve the uncertainty surrounding the application of the minimum contacts doctrine in a products liability context. The author examines the nature of the uncertainty, and forecasts the effects that this case will have on products liability litigation in the future, limiting the analysis to the due process limitations faced by state long arm statutes. The author concludes that the Court\u27s decision in World-Wide Volkswagen is inconsistent with the ultimate goals of the minimum contacts doctrine

    Narrow complex tachycardia with discordant 12-lead RP intervals.

    We present a case of supraventricular tachycardia (SVT) with discordant RP intervals on 12‑lead ECG, rendering the diagnosis initially challenging. However, clues present on the ECG during SVT along with an ECG in sinus rhythm helped to elucidate the mechanism and the underlying diagnosis

    Flight Tests, Performances and Flight Certification of a Twin-Engine Light Aircraft

    This paper deals with flight test activities performed on P2006T, a twin-engine light aircraft recently designed and produced by Tecnam. Research activities and flight tests have been conducted during the flight certification of P2006T for the normal category under CS-23. All the acquired data and flight results presented have been focused on both aircraft certification and on aircraft performances, stability and flight qualities measurement. The data have been acquired through a light, accurate and reliable flight instrumentation available at DIAS (Department of Aerospace Engineering). Some flight data about aircraft leveled speed, stall speed, climb characteristics and ground performances (take-off and landing) will be presented. After preliminary flight tests, winglets have been designed and added to the final configuration in order to obtain good climb performances also in OEI (One Engine Inoperative) conditions. Accurate stall tests have been performed in all configurations and influence of both entry-rate and load factor on stall speed have been highlighted. Excellent ground performances have been measured with short take-off and landing distances compared with similar airplanes. All measured flight performances can be considered very good for this aircraft category and have been used to demonstrate aircraft safety and to obtain CS23 certification

    Accurate measurement of a 96% input coupling into a cavity using polarization tomography

    Pillar microcavities are excellent light-matter interfaces providing an electromagnetic confinement in small mode volumes with high quality factors. They also allow the efficient injection and extraction of photons, into and from the cavity, with potentially near-unity input and output-coupling efficiencies. Optimizing the input and output coupling is essential, in particular, in the development of solid-state quantum networks where artificial atoms are manipulated with single incoming photons. Here we propose a technique to accurately measure input and output coupling efficiencies using polarization tomography of the light reflected by the cavity. We use the residual birefringence of pillar microcavities to distinguish the light coupled to the cavity from the uncoupled light: the former participates to rotating the polarization of the reflected beam, while the latter decreases the polarization purity. Applying this technique to a micropillar cavity, we measure a 53±2%53 \pm2 \% output coupling and a 96±1%96 \pm 1\% input coupling with unprecedented precision.Comment: 6 pages, 3 figure

    Catheter entrapment in a pulmonary vein: a unique complication of pulmonary vein isolation.

    Get PDF
    Ablation strategies for the treatment of atrial fibrillation (AF) are associated with several potential complications. During electro-anatomic mapping of the left atrium (LA) before ablation, the ablation catheter was entrapped in the right inferior pulmonary vein (RIPV). After multiple unsuccessful gentle tractions, stronger maneuvers with rotation of the catheter slowly allowed its retrieval. Examination of the catheter showed a thin, translucent membrane covering its tip, suggesting complete stripping of a vein branch. Occlusion of the superior branch of the RIPV was confirmed by LA angiogram. During the following days, no pericardial effusion was noted, but the patient complained of light chest pain and mild hemoptysis, spontaneously resolving within 48 h. This case shows that catheter entrapment and mechanical disruption of a PV branch can be a rare potential complication of AF ablation. In this case, the outcome was spontaneously favorable and symptoms only included transient mild hemoptysis
