Serial defaults, serial profits: Returns to sovereign lending in Habsburg Spain, 1566-1600

Philip II of Spain accumulated debts equivalent to 60% of GDP. He also defaulted four times onhis short-term loans, thus becoming the first serial defaulter in history. Contrary to a commonview in the literature, we show that lending to the king was profitable even under worst-casescenario assumptions. Lenders maintained long-term relationships with the crown. Lossessustained during defaults were more than compensated by profits in normal times. Defaultswere not catastrophic events. In effect, short-term lending acted as an insurance mechanism,allowing the king to reduce his payments in harsh times in exchange for paying a premium intranquil periods. © 2010 Elsevier Inc.

La secuencia onírica y la construcción de la interioridad en la ficción serial contemporánea.

El presente trabajo trata sobre el imaginario de la interioridad en el contexto de la ficción serial contemporánea. Sin establecer una ruta definida por una variable formal determinada (autor, género, corriente estilísitca, etc.) enfocaré este estudio en el recurso expresivo de la secuencia onírica, entendiendo por tal no sólo la filmación de escenas pertenecientes al ámbito del sueño sino también a la recreación del delirio, la alucinación, las visiones, etc.En un sentido amplio, dada la naturaleza del tema escogido, se hará necesaria una reflexión sobre la relación entre vigilia, sueño, tiempo e identidad, así como una reflexión sobre el modo en que la redefinición de estos conceptos desencadena paralelamente una nueva relación de los componentes narrativos con el relato mismo.

Quantum wire with periodic serial structure

Electron wave motion in a quantum wire with periodic structure is treated by direct solution of the Schrödinger equation as a mode-matching problem. Our method is particularly useful for a wire consisting of several distinct units, where the total transfer matrix for wave propagation is just the product of those for its basic units. It is generally applicable to any linearly connected serial device, and it can be implemented on a small computer. The one-dimensional mesoscopic crystal recently considered by Ulloa, Castaño, and Kirczenow [Phys. Rev. B 41, 12 350 (1990)] is discussed with our method, and is shown to be a strictly one-dimensional problem. Electron motion in the multiple-stub T-shaped potential well considered by Sols et al. [J. Appl. Phys. 66, 3892 (1989)] is also treated. A structure combining features of both of these is investigated

Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases

Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned and operated upon with the guided surgery technique. Results: A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complications comprised a lack of primary stability, while the postoperative complications consisted of infections and a lack of implant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of the provisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. The degree of patient satisfaction was evaluated using a verbal scale. Conclusions: Implant restoration with the guided surgery technique and immediate functional loading is a predictable procedure, provided patient selection and the surgical technique are adequate, affording lesser postoperative morbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and function

Orofacial pain of cardiac origin, serial of clinical cases

Objective: To determine the clinical characteristics of the orofacial pain of cardiac origin in patients visited when doing a treadmill exercise test, at the cardiology service of the Can Ruti Hospital in Badalona (Barcelona, Spain). Study design: The sample of that study included thirty patients visiteding when doing a treadmill exercise test, at the cardiology service. The questionnaire has been asked to a sample of 30 patients. Results: Eleven of the 30 patients included in this study presented craniofacial pain before or during the cardiac seizure. The location of the pain was bilateral, non-irradiated at the mandible in all cases. The intensity of the pain was from slight to severe. The frequency of the appearance of the pain was paroxysmal in 8 cases and constant in three cases, and the duration was from a few hours to a maximum of 14 days. Discussion: The cardiac pain in craniofacial structures is usually bilateral, compared to odontogenic pain which is always unilateral. The pain of cardiac origin is considered atypical because of its location, but about the 10 % of the cases, the cardiac ischemia has its primary manifestation in orofacial structures. Conclusions: Eleven patients referred a bilateral non-irradiated mandibular pain, with intensity from slight to severe, and with a paroxystic frequency in eight cases and a constant frequency in three cases. Just one patient referred pain during the treadmill exercise test. In all cases the pain disappeared after the cardiac surgery or the administration of vasodilators.
