A modified prosthesis for the treatment of malignant esophagotracheal fistula
1988
Esophagotracheal fistula is usually a sequela of irradiation or laser treatment of advanced carcinoma of the esophagus or the tracheobronchial tree. Resection of the tumor in these cases is not possible, and palliative bypass surgery is highly risky. The peroral placement of a prosthesis is less invasive, but conventional prostheses often fail to occlude the fistula. The authors regularly use an endoscopic multiple-diameter bougie for dilation. After dilation, a specially designed prosthesis is pushed through the tumor stenosis to block the fistula. This procedure can be done without general anesthesia. The funnels of conventional prostheses cannot cover the fistula when there is either a w…
Más allá de Vainica Doble: Carmen Santonja, pintora
2009
Este artículo analiza la trayectoria pictórica de Carmen Santonja (Madrid, 1934- 2000). Aunque ha sido más conocida como cantante, ya que formó parte del célebre grupo Vainica Doble, C. Santonja también se dedicó con intensidad a otras disciplinas artísticas cine, televisión , destacando especialmente su vocación pictórica. Sus obras, como su música, reflejarán el gusto por la naturaleza dentro de una estética pop, mostrando gran interés por la experimentación, que le llevará a la creación de nuevas técnicas, como el decollage.

Optimal Pre-Oxygenation: The Nasoral-System
1994
The human body’s intra-and extrapulmonary O2 reserves, i.e. the oxygen stores of the functional residual capacity (FRC) and the blood, will be rapidly depleted during any kind of respiratory arrest (apnea). Application of oxygen prior to iatrogenic apnea (e.g. for endotracheal intubation procedures), therefore, commonly is discussed [e.g. Miller, 1990] as the proposed measure designed to achieve an increase in the human body’s oxygen stores sufficient to avoid hypoxemia. This prophylactic application of oxygen simply has become to be termed “pre-oxygenation”, regardless of the amount of increase in the O2 stores actually achieved. A myriad of different techniques and procedures are practica…
Discrimination and provenances of Phoenician red slip ware using both the solid state electrochemistry and petrographic analyses
2020
[EN] Solid state electrochemistry based on the voltammetry of immobilized microparticles (VIMP) methodology is applied to a series of 80 Phoenician Red Slip samples from the archaeological sites of Motya (Sicily, Italy), Mogador (Morocco), Ramat-Rahel (Israel), Sulky (Sardinia, Italy), Tas Silg (Malta), Pantelleria (Italy), and Cadiz (Spain), dated from the 8(th) to the 6(th) century BC. Upon attachment of sub-microsamples to graphite electrodes in contact with aqueous H2SO4 electrolyte, voltammetric features due to the reduction of Fe(III) minerals and the oxidation of Fe(II) ones, complemented with electrocatalytic effects on oxygen reduction and oxygen evolution reactions, provide charac…
Dating archeological lead artifacts from measurement of the corrosion content using the voltammetry of microparticles.
2011
A methodology for dating archeological lead artifacts based on the voltammetry of microparticles is described. This methodology is based on the comparison of the height of speci¿c voltammetric features from PbO2 and PbO corrosion products formed under long-term alteration conditions. Calibration of the method was performed with the help of a series of well-documented lead pieces from the funds of di¿erent museums of the Comunitat Valenciana (Spain) covering from the ¿fth century B.C. to present day. The variation of peak currents with the time of corrosion can be¿tted to the same potential rate law as that found by Reich (R = 0.070 ( 0.005), using measurements on the Meissner fraction in th…
Hyperoxic Intubation Apnoea: An In Vivo Model for the Proof of the Christiansen-Douglas-Haldane Effect
1989
The Christiansen-Douglas-Haldane effect (HALDANE effect) describes the different CO2 binding capacity of haemoglobin on its degree of oxygenation and was first demonstrated in vitro in 1914 (Christiansen, Douglas and Haldane, 1914).
Electroanalytical techniques in archaeological and art conservation
2017
[EN] The application of electrochemical techniques for obtaining analytical information of interest in the fields of archaeometry, conservation and restoration of cultural heritage goods is reviewed. Focused on voltammetry of immobilised particles and electrochemical impedance spectroscopy techniques, electrochemical measurements offer valuable information for identifying and quantifying components, tracing provenances and manufacturing techniques and provide new tools for authentication and dating.
La formula di Mucio Scevola, i nomi delle azioni e l'agere per concepta uerba
2021
The formula Mucii Scaeuolae depicted in the fresco of ‘The Jurist’s Villa’ upon the Aniene river probably does not refer to a specific action of the formulary procedure (agere per formulas). The pratice of naming some actions after the nomen gentilicium of a praetor is in fact attested in our sources only after the so-called codification of the Edictum Perpetuum in the age of Hadrian. The discovery of the fresco leads us to reflect once again on the origins of the formulary procedure, since the Mucius Scaevola of the fresco inscription may well refer to the jurist Quintus Mucius Scaevola. This in turn might suggest both that he was actually owner of the villa and that it was he who introduc…
La reapertura de la Biblioteca Ambrosiana de Milán

La colección de pintura antigua del Museo Nacional de Cerámica y Artes Suntuarias "González Martí"
2010
El Museo Nacional de Cerámica y Artes Suntuarias "González Martí", conocido principalmente por sus valiosísimas colecciones cerámicas, es también poseedor de una importante colección de pinturas. La mayor parte de este conjunto heterogéneo de obras es totalmente desconocida para el gran público ya que, por problemas de espacio expositivo, se conserva necesariamente en los almacenes del museo. El objetivo del presente estudio será dar a conocer una pequeña parte de esta colección, aquella que comprende las pinturas realizadas en los siglos XV-XVIII. Para ello se indagará en aspectos generales de la misma, como sus orígenes y formación, y otros más concretos que harán referencia a cada una de…
