Obesity interferes with the orosensory detection of long-chain fatty acids in humans
2014
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
Towards understanding the complexity of cardiovascular oscillations: Insights from information theory.
2018
Abstract Cardiovascular complexity is a feature of healthy physiological regulation, which stems from the simultaneous activity of several cardiovascular reflexes and other non-reflex physiological mechanisms. It is manifested in the rich dynamics characterizing the spontaneous heart rate and blood pressure variability (HRV and BPV). The present study faces the challenge of disclosing the origin of short-term HRV and BPV from the statistical perspective offered by information theory. To dissect the physiological mechanisms giving rise to cardiovascular complexity in different conditions, measures of predictive information, information storage, information transfer and information modificati…
Multilayered cultural identity and the perception of the self
2012
This qualitative study examines the reciprocal relationship between a person’s multilayered cultural identity (MCI) and the concept of self (CoS), that is presented purely on a theoretical level and encompasses various theories. Nowadays, in an increasingly globalising world, it is not enough to merely look at a national, ethnic or other type of identity. It is important to realise that there are different layers in an identity that one can view themselves through. The ways an individual perceives themselves through their multicultural background can also be different. This thesis helps identify the ways a person can see themselves. The thesis also attempts to explain the varied nature of o…

Determination of Brain Death/Death by Neurologic Criteria
2020
Importance: There are inconsistencies in concept, criteria, practice, and documentation of brain death/death by neurologic criteria (BD/DNC) both internationally and within countries. Objective: To formulate a consensus statement of recommendations on determination of BD/DNC based on review of the literature and expert opinion of a large multidisciplinary, international panel. Process: Relevant international professional societies were recruited to develop recommendations regarding determination of BD/DNC. Literature searches of the Cochrane, Embase, and MEDLINE databases included January 1, 1992, through April 2020 identified pertinent articles for review. Because of the lack of high-quali…
Use of fiber-section beam elements for modelling the monotonic flexural response of RC jacketed columns
2021
Abstract The use of reinforced concrete (RC) jacketing is a common technique for retrofitting existing RC columns with poor structural performances. Literature studies highlighted that the relative slip occurring at the interface between the new and the old concrete can affect substantially the flexibility and the strength of the retrofitted member. For this reason, several interface treatments are usually applied, aiming to induce a monolithic behaviour to the column. However, despite the commonness of RC jacketing, a limited number of studies investigated numerical modelling strategies for including these phenomena, especially with reference to the development of numerical models for desi…
Air stable hybrid organic-inorganic light emitting diodes using ZnO as the cathode
2007
An air stable hybrid organic-inorganic light emitting device is presented. This architecture makes use of metal oxides as charge injecting materials into the light emitting polymer, avoiding the use of air sensitive cathodes commonly employed in organic light emitting diode manufacturing. We report the application of zinc oxide as a cathode in an organic light emitting device. This electroluminescent device shows high brightness levels reaching 6500 cd/m2 at voltages as low as 8 V. Compared to a conventional device using low workfunction metal cathodes, our device shows a lower turn-on voltage and it can operate in air.
Técnicas fibrobroncoscópicas especiales: lavado broncoalveolar, biopsia bronquial y biopsia transbronquial
2005
Este artículo completa las recomendaciones sobre el uso y aplicaciones del broncoscopio flexible en la infancia, del Grupo de Técnicas de la Sociedad Española de Neumología Pediátrica, incluyendo los procedimientos que, con fines diagnósticos y ocasionalmente terapéuticos, se aplican con mayor frecuencia durante la práctica de la broncoscopia flexible: el lavado broncoalveolar y las biopsias bronquial y transbronquial. Se realizan también recomendaciones para la práctica del lavado broncoalveolar no broncoscópico.Se revisan las indicaciones, contraindicaciones, recursos materiales, el cuidado y monitorización del paciente previo, durante y posterior al procedimiento, y las complicaciones de…
Simplified technique for constitutive analysis of SFRC
2014
Steel fibre reinforced concrete (SFRC) has become widespread material in areas such as underground shotcrete structures and industrial floors. However, due to the absence of material models of SFRC reliable for numerical analysis, application fields of this material are still limited. Due to interaction of concrete with fibres, a cracked section is able to carry a significant portion of tensile stresses, called the residual stresses. In present practices, residual stresses used for strength, deflection and crack width analysis are quantified by means of standard tests. However, interpretation of these test results is based on approximation using empirically deduced relationships, adequacy o…
