Comparación del Vitalograph COPD-6® y del Air Smart Spirometer® con la espirometría estándar en el despistaje y el diagnóstico de los pacientes con E…
2020
La enfermedad pulmonar obstructiva crónica (EPOC) está infradiagnosticada aunque mejora su evo- lución y pronóstico si se trata precozmente y su principal tratamiento es la abstinencia tabáquica. El objetivo principal de este estudio es comparar los espirómetros de campo COPD-6 ® (Vitalograph) y Air Smart Spirometer® con la espirometría estándar en el diagnóstico de la obstrucción bronquial. Los objetivos secundarios son: determinar cuál de los dos espirómetros estudiados es más eficaz y/o eficiente; detectar los falsos positivos que generan y valorar su aportación a la deshabituación tabá- quica. Participaron 185 pacientes del Centro de Salud Fuensanta con o sin síntomas o signos sugestivo…
Tecnica scintillometrica per la misura dell’evapotraspirazione effettiva: principi teorici ed esempi applicativi

Estudio de la tasa de implantación, tras tratamiento quirúrgico histeroscópico de las alteraciones morfológicas de la cavidad endometrial, en mujeres…
2020
A pesar de los grandes avances en el campo de la reproducción, la prevalencia del fallo de implantación es alta. Cada vez se presta más atención a la cavidad endometrial, ya que aun teniendo unos preembriones de alta calidad, y el gran avance de las TRA, el fallo de implantación sigue siendo un problema frecuente en el que el útero podría jugar un papel más importante de lo que se consideraba anteriormente. La histeroscopia ha sido considerada el “patrón oro” para la evaluación de la cavidad uterina; sin embargo, la Sociedad Europea de Reproducción Humana y Embriología (ESHRE) y la OMS, indican que la histeroscopia solo debe ser utilizada para confirmación y tratamiento de patologías uterin…
Multiparameter quantum critical metrology
2022
Single parameter estimation is known to benefit from extreme sensitivity to parameter changes in quantum critical systems. However, the simultaneous estimation of multiple parameters is generally limited due to the incompatibility arising from the quantum nature of the underlying system. A key question is whether quantum criticality may also play a positive role in reducing the incompatibility in the simultaneous estimation of multiple parameters. We argue that this is generally the case and verify this prediction in paradigmatic quantum many-body systems close to first and second order phase transitions. The antiferromagnetic and ferromagnetic 1-D Ising chain with both transverse and longi…
Estudio retrospectivo a largo plazo de los resultados de dos técnicas de cirugía bariátrica en pacientes con obesidad mórbida: Bypass gástrico y gast…
2020
La obesidad mórbida (Índice de Masa Corporal >40) se asocia a comorbilidades que pueden poner en riesgo la vida del paciente. El bypass gástrico en “y de roux” y la gastrectomía vertical son dos de las técnicas bariátricas más realizadas, pero, aunque se postulen como tratamientos eficaces frente a esta obesidad, no están exentas de riesgo. El objetivo principal de este estudio es conocer los efectos que estas técnicas tienen sobre el paciente a medio-largo plazo (2-5 años) siendo los seguimientos a los 0, 6, 12, 24 y 60 meses. Se realiza un estudio observacional retrospectivo y comparativo de una muestra de 244 pacientes (133 intervenidos mediante by pass gástrico en “y de roux” y 111 medi…
When virtual and real worlds coexist: Visualization and visual system affect spatial performance in augmented reality
2021
New visualization approaches are being actively developed aiming to mitigate the effect of vergence-accommodation conflict in stereoscopic augmented reality; however, high interindividual variability in spatial performance makes it difficult to predict user gain. To address this issue, we investigated the effects of consistent and inconsistent binocular and focus cues on perceptual matching in the stereoscopic environment of augmented reality using a head-mounted display that was driven in multifocal and single focal plane modes. Participants matched the distance of a real object with images projected at three viewing distances, concordant with the display focal planes when driven in the mu…
Binocular vision alterations after refractive and cataract surgery: a review.
2018
To review binocular and accommodative disorders documented after corneal or intraocular refractive surgery, in normal healthy prepresbyopic patients. A bibliographic revision was performed; it included works published before 1st July 2017 where accommodation and/or binocularity was assessed following any type of refractive surgical procedure. The search in Pubmed yielded 1273 papers, 95 of which fulfilled the inclusion criteria. Few publications reporting binocular vision and/or accommodative changes after refractive surgery in normal subjects were found. The reduction in fusional vergence is the most frequently reported alteration. Anisometropia is an important risk factor for postoperativ…
The Context of Rural–Urban Relationships in Finland, France, Hungary, The Netherlands and Spain
2009
This paper presents a comprehensive view of the empirical research findings concerning rurban relationships in different European countries (Finland, France, Hungary, the Netherlands and Spain), through two types of rurban territories: those that are placed close to (or included in) a metropolitan area and those that are close to (and influenced by) an important tourist area or place. Its main aim is to show the diversity of European experiences with regard to urban pressure in this type of areas, highlighting the socio-economic and institutional contexts in explaining similarities and differences between five countries. The results will review the various meanings of ‘rural’ and ‘rurality’…
Territorial Connection and Cohesion - The Case of Agrigento Inland Area
2014
The Europe 2020 strategy and the Horizon 2020 program can begin a real path about the role that the city will be able play for a new development. Usually, it is in the cities that are intensifying tangible and intangible social relations and, given that they focused almost 70% of the world population, it is clear that the city must begin to start any development scenario: the problems / opportunities related to the management of natural resources, energy to move. The culture is a «primary factor of urban creativity (...), the city's identity that has its roots the program schedule of history and extends its branches in the future» [4], awaiting a new model of development local self-sustaina…
Environment in Megacities: Tehran Waterscapes
2021
Defining contemporary urban paradigms is the challenge of this time, especially when the urban dynamics are so fluid they spread uncontrollably in overextended and overpopulated territories. This is the case for megacities, metropolitan areas with more than 10 million inhabitants, which place the emphasis on how to manage energy consumption in such filled places. In this frame, the city of Tehran, the capital of the Islamic Republic of Iran, scene of political and cultural disputes, administrative and economic headquarter of the country, with its nearly 15 million residents and a daily traffic of more than 20 million people, is currently one of the most populous cities in the world and repr…
