OLIVE OILS FROM THE MEDITERRANEAN BASIN
2021
Sicily, located in the center of the Mediterranean basin, has represented for centuries a meeting point between different civilizations that have contributed to creating a wide genetic diversification of the Sicilian olive heritage, which has led to an improvement in the quality of the olive trees. In Sicily, today this diversification is comparable with other typical varieties of the Mediterranean basin, especially from an analytical point of view. Two international varieties were analyzed such as Arbequina and Koroneiki, two main Sicilian varieties such as Biancolilla and Nocellare del Belice, two minor varieties in the Sicilian varietal panorama such as Crastu and Tonda Iblea and finally…
Soft tissue sarcomas in the precision medicine era: new advances in clinical practice and future perspectives
2018
Soft tissue sarcomas (STSs) represent a rare and heterogeneous group of solid tumours derived from mesenchymal progenitors and account for 1% of all adult malignancies. Although in the last decade anthracycline-based chemotherapy single agent or in combinations has been able to improve clinical benefits, prognosis is still poor and STSs represent an important unmet medical need. Continuous advances in cancer genetics and genomics have contributed to change management paradigms of STSs as it occurred for other solid tumours. Several treatments have been recently developed with the specific aim of targeting different cell pathways and immune-checkpoints that have been recognized to drive tumo…
Educar para la salud en tiempos de pandemia
2021
La experiencia de la pandemia que estamos viviendo exige repensar la educación para la salud. En este trabajo lo hacemos a partir de dos conceptos procedentes de la Declaración Universal de los Derecho Humanos: primero, entender que el fin de la educación es el pleno desarrollo de la persona; y segundo, que los deberes para con la comunidad contribuyen a ese desarrollo. A partir de ellos, defendemos una concepción de la educación para la salud basada en el carácter relacional del ser humano, en la relevancia de los determinantes sociales de la salud y en los peligros del entorno digital, a pesar de los enormes beneficios que ha aportado durante la pandemia.
Moros y cristianos. De la batalla festiva a la discursiva
2008
Hace poco más de un año se acordaba en España admitir a trámite en el Congreso de los Diputados la proposición no de ley del Grupo Parlamentario Popular relativa a la proclamación de las "fiestas de moros y cristianos" como obras maestras del patrimonio oral e inmaterial de la humanidad. La solicitud se contextualiza en la democratización y universalización que el patrimonio ha experimentado y se explica por la vertiente cada vez más mercantilista de los procesos de patrimonialización. En el caso que nos ocupa la presentación estuvo envuelta en una interesante discusión política sobre la "tradición", la "libertad" y la "amenaza". Este artículo analiza la polémica sobre estas fiestas y su pr…
How does the journal impact factor affect the CV of PhD students?
2014
In his editorial “Dear DORA”, Howy Jacobs commented on the recent San Francisco Declaration of Research Assessment (DORA) to address the misuse of the journal impact factor (IF) and discussed alternatives. DORA stipulates that the IF must not be used as a surrogate measure of the quality of individual research articles, or to assess an individual scientist's contributions in hiring, promotion and funding decisions. DORA and many other commentators, such as Howy Jacobs, therefore advocate the use of additional, alternative metrics and other measures to make a more fair and realistic judgment about the quality of a scientist's or …
Conjugating pillararene dye in dye-sensitized solar cells
2021
Summary The improvement of open-circuit voltage (VOC) is a crucial goal to develop efficient dye-sensitized solar cells (DSSCs). Here, conjugating pillar[5]arene dyes (PPI and PPII) are designed, synthesized, and applied in DSSCs. The presence of pillar[5]arene moiety in the dyes inhibits the dye aggregation and charge recombination in the DSSCs, leading to the enhancement of VOC. PPI with a single D-π-A backbone and a pillar[5]arene moiety achieves a VOC of 715 mV, which is much higher than the reference dye (VOC of 674 mV) with the same D-π-A backbone but no pillar[5]arene moiety. PPII with 2 D-π-A backbones also achieves a VOC of 746 mV and a much higher short-circuit photocurrent (JSC) …
Multinucleon transfer reactions in closed-shell nuclei
2007
Multinucleon transfer reactions in 40Ca+96Zr and 90Zr+208Pb have been measured at energies close to the Coulomb barrier in a high resolution gamma-particle coincidence experiment. The large solid angle magnetic spectrometer PRISMA coupled to the CLARA gamma-array has been employed. Trajectory reconstruction has been applied for the complete identification of transfer products. Mass and charge yields, total kinetic energy losses, gamma transitions of the binary reaction partners, and comparison of data with semiclassical calculations are reported. Specific transitions in 95Zr populated in one particle transfer channels are discussed in terms of particle-phonon couplings. The gamma decays fro…
Confinement in Wendelstein 7-X limiter plasmas
2017
Observations on confinement in the first experimental campaign on the optimized Stellarator Wendelstein 7-X are summarized. In this phase W7-X was equipped with five inboard limiters only and thus the discharge length restricted to avoid local overheating. Stationary plasmas are limited to low densities <2–3 · 1019 m−3. With the available 4.3 MW ECR Heating core Te ~ 8 keV, Ti ~ 1–2 keV are achieved routinely resulting in energy confinement time τE between 80 ms to 150 ms. For these conditions the plasmas show characteristics of core electron root confinement with peaked Te-profiles and positive Er up to about half of the minor radius. Profiles and plasma currents respond to on- and off-axi…
Magnetic configuration effects on the Wendelstein 7-X stellarator
2018
The two leading concepts for confining high-temperature fusion plasmas are the tokamak and the stellarator. Tokamaks are rotationally symmetric and use a large plasma current to achieve confinement, whereas stellarators are non-axisymmetric and employ three-dimensionally shaped magnetic field coils to twist the field and confine the plasma. As a result, the magnetic field of a stellarator needs to be carefully designed to minimize the collisional transport arising from poorly confined particle orbits, which would otherwise cause excessive power losses at high plasma temperatures. In addition, this type of transport leads to the appearance of a net toroidal plasma current, the so-called boot…
Overview of diagnostic performance and results for the first operation phase in Wendelstein 7-X (invited)
2016
Wendelstein 7-X, a superconducting optimized stellarator built in Greifswald/Germany, started its first plasmas with the last closed flux surface (LCFS) defined by 5 uncooled graphite limiters in December 2015. At the end of the 10 weeks long experimental campaign (OP1.1) more than 20 independent diagnostic systems were in operation, allowing detailed studies of many interesting plasma phenomena. For example, fast neutral gas manometers supported by video cameras (including one fast-frame camera with frame rates of tens of kHz) as well as visible cameras with different interference filters, with field of views covering all ten half-modules of the stellarator, discovered a MARFE-like radiati…
