Arquitectura, símbolo y función en la iglesia de Santiago de Villena
2011
En este trabajo se analiza la fábrica, la ornamentación y el significado simbólico y funcional de la iglesia de Santiago de Villena en la encrucijada de los siglos XV y XVI, considerando sus antecedentes en la arquitectura tardogótica mediterránea y la incorporación de elementos del nuevo lenguaje renacentista. Se prestará especial atención a la vinculación de la obra con su promotor, Sancho de Medina, y con los artistas que en ella pudieron trabajar como un maestro del círculo de Pere Compte, Miguel de Magaña, Jacobo Florentín y Jerónimo Quijano y se indaga sobre el posible simbolismo salomónico de su arquitectura.
El sentit de l'ontologia en W. V. O. Quine
2004
El corrent positivista va conèixer molt aviat els seus heterodoxos. L'heterodòxia consistia fonamentalment en el fet de no acceptar la tesi de la reducció de la filosofia a l'anàlisi logicosintàctica del llenguatge i en el de ser reticents al rebuig dogmàtic dc l'especulació filosòfica. Bertrand Russell ja clamà al seu dia en defensa de l'especulació filosòfica i contra el dogmatisme positivista. I Quine fou un dels primers. filòsofs que, tot i que contaminat de positivisme però híbrid de positivisme i russellianisme, va obrir les portes a l'ontologia.
A través de la frontera: los maestros de Castilla y la arquitectura tardogótica valenciana
2014
Este trabajo estudia el papel de los maestros canteros castellanos en el contexto de la arquitectura tardogótica valenciana. En primer lugar, se presta atención a la cuestión general de la transmisión del conocimiento técnico en los oficios de la construcción en un período de innovación respaldada por los promotores y las instituciones públicas. A continuación se consideran algunos casos de estudio para determinar qué tipo de contribución tuvo la movilidad de los maestros canteros provenientes de Castilla en Valencia entre 1350 y 1520. Finalmente, se tratan cuestiones como la integración social en las corporaciones y oficios, la competición con los maestros constructores locales y la difusi…
The effect of cooperative infrastructure fees on high-speed rail and airline competition
2021
Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
Correction of the unfavourable effects of vasopressin by nitroglycerin infusion
1982
Nitroglycerin was administered with vasopressin to prevent adverse effects. Vasopressin 0.25U . 70 kg-1 min-1 was infused intravenously in four dogs for 40 minutes, when a venous infusion of nitroglycerin 1.2 micrograms . kg-1 . min-1 was added for 20 minutes. Nitroglycerin 1.2 micrograms . kg-1 . min-1 alone was infused intravenously in another four dogs for 40 minutes. The venous blood pressures (mesenteric and central) and arterial pressures (mesenteric and femoral), the electrocardiogram and arterio-venous difference were recorded. Nitroglycerin was shown to annul the unfavourable effects of vasopressin without altering its efficacy upon portal pressure.
The role of pedogenic overprinting in the obliteration of parent material in some polygenetic landscapes of Sicily (Italy)
2016
Abstract Many soils older than the Holocene have experienced several changes, and possess properties that may be due to the complex effect of several stages of soil development; these soils are called polygenetic. It is still rather unclear, however, if, as time elapses, pedogenic processes tend to diverge generating different soils, or converge towards increasingly similar soils. We studied five pedons (37°60′N, 13°90′E) exposed to present weathering simultaneously since the Holocene but located on Upper Miocene or Holocene parent material. Their XRD and FTIR clay mineralogy reveal an overall homogeneity; smectites, calcite and gypsum reach the thermodynamic equilibrium, a slight undersatu…
Hemoprotozoa of domestic animals in France: Prevalence and molecular characterization
2008
Very limited information is available on epizootiology of haematozoan infections in French domestic animals. In an attempt to address this issue, prevalence of piroplasmida was studied in carnivores and ruminants, whereas prevalence of Hepatozoon spp. was only investigated in carnivores. In total, 383 animals were included in the survey (namely 116 cats, 108 dogs, 91 sheep and 68 cows). Parasite diagnosis was carried out using molecular methods such as PCR and sequencing of the 18S rRNA gene. In addition, ruminant samples were analyzed with the reverse line blotting technique (RLB). Results of RLB and PCR plus sequencing were in total agreement. In carnivores, haematozoan prevalence was clo…
Serological Evidence for Multiple Strains of Canine Norovirus in the UK Dog Population
2013
International audience; Noroviruses are associated with intestinal disease in humans, cows, pigs, mice, and, more recently, dogs. In 2007, the first canine norovirus (CNV) was identified and characterized in Italy. Subsequent studies have identified CNV in stools of dogs from Portugal, Greece, and the United States. To investigate the prevalence of CNV in the UK dog population, 228 canine stool samples were screened for CNV by qPCR, and 396 serum samples were screened for anti-CNV antibodies. qPCR of RNA extracted from canine stool samples did not reveal any CNV-positive samples, based on samples collected from diarrhoeic and control dogs in 2012-2013. CNV virus-like particles to three diff…
Biophotonics in veterinary medicine: the first steps toward clinical translation
2019
In this paper, we analyzed the current situation and the potential of biophotonics and biomedical optics in veterinary medicine. Promising optical techniques such as optical coherence tomography, pulse oximeter, and hyperspectral imaging have been clinically translated into human medicine. But even though human and small animal medicine share personalized and state-of-the-art approach, biophotonics remains rarely exploited in the canine and feline medicine. However, there are some biophotonics studies in veterinary oncology which addressed tumor diagnosis (skin and subcutaneous tumors), prognosis (lymphoma), and therapy (clear surgical margins). Visible and near-infrared spectroscopy served…
Sec61alpha and TRAM are Sequentially Adjacent to a Nascent Viral Membrane Protein during its ER Integration
2007
Co-translational integration of a nascent viral membrane protein into the endoplasmic reticulum membrane takes place via the translocon. We have been studying the early stages of the integration of a double-spanning plant viral movement protein to gain insights into how viral membrane proteins are transferred from the hydrophilic interior of the translocon into the hydrophobic environment of the bilayer, where the transmembrane (TM) segments of the viral proteins can diffuse freely. Photocrosslinking experiments reveal that this integration involves the sequential passage of the TM segments past Sec61alpha and translocating chain-associating membrane protein (TRAM). Each TM segment is first…
