La multifuncionalidad del mundo rural
2002
En este artículo se describen las bases conceptuales de la multifuncionalidad de la agricultura, y se analiza hasta qué punto pueden servir para justificar la intervención pública en apoyo del sector. A continuación, se destacan algunos aspectos concretos que tienen que ver con la multifuncionalidad en las áreas relacionadas con la biodiversidad, el desarrollo rural y la seguridad alimentaria para, finalmente, contemplar las posibilidades que ofrecen las actuales normas de la Organización Mundial del Comercio (OMC) a la hora de tener en cuenta las denominadas «preocupaciones no comerciales» (non-trade concerns) y, entre ellas, las relacionadas con la multifuncionalidad. ereig@uv.es
Collective spontaneous emission of two entangled atoms near an oscillating mirror
2020
We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state and in the presence of an oscillating mirror. We assume that the two atoms, one in the ground state and the other in the excited state, are prepared in a correlated (symmetric or antisymmetric) {\em Bell}-type state. We also suppose that the perfectly reflecting plate oscillates adiabatically, with the field modes satisfying the boundary conditions at the mirror surface at any given instant, so that the time-dependence of the interaction Hamiltonian is entirely enclosed in the instantaneous atoms-wall distance. Using time-dependent perturbation …
Externalism, inclusion, and knowledge of content
2003
En este trabajo abordo la cuestión de si el autoconocimiento es compatible con una individuación externista del contenido mental. En contra de algunas posiciones, considero el autoconocimiento como un logro cognitivo genuino. Aunque no es incorregible ni infalible, el autoconocimiento es directo (no inferencial), a priori (no basado en la investigación empírica), y dotado de especial autoridad y presunción de verdad. El problema consiste en saber si el autoconocimiento, así entendido, es compatible con el externismo. Mi respuesta será afirmativa. Defenderé esta clase de compatibilismo frente a distintas objeciones, sobre todo aquellas que se basan en la posibilidad de que un individuo sea s…
An innervated retroauricular skin flap for total earlobule reconstruction.
2003
In this article, the authors describe a technique for total earlobule reconstruction in a patient who underwent earlobule excision for basal cell carcinoma. The reconstruction was by means of an innervated retroauricular skin flap, folded double. The flap presented preserved skin sensitivity over all the reconstructed area, which is compromised by those techniques using a cranially or medially based flap which lead to the reconstruction of an insensible earlobule. This is a very important aspect of this technique, especially for those who wear pendant earrings, since a non-sensitive lobule would be more vulnerable to traumas causing laceration. In addition, it allows a good aesthetic result…
Laser Assisted Dirac Electron in a Magnetized Annulus
2021
We study the behaviour of a charge bound on a graphene annulus under the assumption that the particle can be treated as a massless Dirac electron. The eigenstates and relative energy are found in closed analytical form. Subsequently, we consider a large annulus with radius ρ∈[5000,10,000]a0 in the presence of a static magnetic field orthogonal to its plane and again the eigenstates and eigenenergies of the Dirac electron are found in both analytical and numerical form. The possibility of designing filiform currents by controlling the orbital angular momentum and the magnetic field is shown. The currents can be of interest in optoelectronic devices that are controlled by electromagnetic radi…
ICT for external use in Croatian four- and five-star hotels
2016
The Purpose – The objective of the paper is to examine the implementation of advanced technology and promotional supports in hotel companies and to compare their performance in four- and five-star hotels. More specifically, ICT for external use are analysed, i.e. customer relationship management (CRM), communication with customers, promotional supports, and online order receptions. Design/Methodology/Approach – The empirical research took place in 38 upscale (26 four and 12 five-star) hotels located in Croatia, in the regions of Dalmatia, Istria, and Kvarner, and in the city of Zagreb. The data were collected through a structured questionnaire administered mainly during personal interviews …
Destinazione turistica e networks interni ed esterni: il turismo relazionale
2022
The limitation in the relations between people caused by the pandemic today pushes more and more travellers in search of experiences and interactions with the territories, especially those excluded from the current production processes and the dominant market logic. In this context, the tourism of the roots or return tourism is motivated by a need to rediscover their origins, discover them, or trace them in places related to the history of travellers or their families. We, therefore, describe the main dimensions of the relationship tourism model so that it can be applied to root tourism.
Optimal Response to Cardiac Arrest study: Defibrillation waveform effects
2001
Abstract Introduction: Advances in early defibrillation access, key to the “Chain of Survival”, will depend on innovations in defibrillation waveforms, because of their impact on device size and weight. This study compared standard monophasic waveform automatic external defibrillators (AEDs) to an innovative biphasic waveform AED. Material and methods: Impedance-compensated biphasic truncated exponential (ICBTE) and either monophasic truncated exponential (MTE) or monophasic damped sine (MDS) AEDs were prospectively, randomly assigned by date in four emergency medical services. The study design compared ICBTE with MTE and MDS combined. This subset analysis distinguishes between the two clas…
Bending-Shear interaction domains for externally prestressed concrete girders
2013
In prestressed concrete structures, the evaluation of the safety level is generally carried out by separating the bending moment strength and the shear force capacity. Actually interaction between bending moment (M) and shear force (V) can have significant consequences on evaluations in service life, especially when the ultimate limit state (ULS) is considered. In this paper, the M-V interaction is addressed for prestressed concrete girders, in the cases of both bonded and unbonded prestressing tendons. It can be demonstrated, by drawing the interaction domains (M-V), that a significant reduction of the safety level has to be considered when shear force is evaluated together with bending mo…
Mutations of mitochondrial DNA and human death.
1990
In the skeletal muscle of patients with mitochondrial myopathies (Kearns-Sayre syndrome and chronic progressive external ophthalmoplegia) and in the heart and skeletal muscle of healthy persons cells lacking cytochrome c oxidase are found. The respiratory-defective cells have the following features in common: onset of the defect at juvenile or adult age; progressive character of the defect with increasing age; and focal pattern of respiratory-deficient cells (fibers). A statistic mutation of mtDNA in affected cells is suggested to cause the defect of mitochondrial function. It is postulated that the continuous accumulation of respiratory-deficient cells, mainly in the human heart with incre…
