LAS REFORMAS INSTITUCIONALES COMO MEDIO DE FORTALECIMIENTO DE LA DEMOCRACIA, Y COMO COMBATE CONTRA LA CORRUPCIÓN Y LA IMPUNIDAD: UNA CONTRIBUCIÓN PAR…
2019
Es común ver regímenes dictatoriales o conflictos armados, o ambos, repetidos en el mismo país. Esto nos invita a iniciar una reflexión sobre la necesidad de demostrar que la implementación y puesta en marcha de una agenda de "transición política" debe centrarse en la seriedad y en el tipo de reformas institucionales a adoptar, ya que se trata de medidas importantes y elementales para garantizar el fortalecimiento del Estado de Derecho, la reconstrucción del Estado, la reconciliación nacional, la consolidación democrática y las respectivas instituciones, que permitan superar el legado autoritario o el conflicto armado que ha vivido una sociedad. Es evidente que cuando hablamos del país que …
Recovery of Lithium Carbonate from Dilute Li-Rich Brine via Homogenous and Heterogeneous Precipitation
2022
An extensive experimental campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li+ similar to 4000 ppm) is presented to identify the best operating conditions for a Li2CO3 crystallization unit. Lithium is currently mainly produced via solar evaporation, purification, and precipitation from highly concentrated Li brines located in a few world areas. The process requires large surfaces and long times (18-24 months) to concentrate Li` up to 20,000 ppm. The present work investigates two separation routes to extract Li+ from synthetic solutions, mimicking those obtained from low-content Li+ sources through selective Li+ separation and further concentration steps: (i) addition of …
Purely organic Vis-to-UV upconversion with an excited annihilator singlet beyond 4 eV
2022
The conversion of visible light into high-energy UV photons via sensitized triplet–triplet annihilation (TTA-UC) could pave the way for several energy-demanding applications. However, only a handful of annihilator chromophores for Vis-to-UV upconversion are known and the current limit for the excited-state energy of the UV emitter in TTA-UC schemes is below 4 eV, i.e., in the spectral region (>310 nm) where the sun still provides a considerable photon flux. Herein, we present a novel biphenyl-based annihilator with a highly fluorescent singlet state at 4.04 eV. This annihilator can be combined with a widely-used TADF sensitizer to yield an efficient blue-light (2.77 eV) driven upconversion …
Antiretroviral genotypic resistance in plasma RNA and whole blood DNA in HIV-1 infected patients failing HAART
2008
The extent to which HIV-1 proviral DNA mutations cause clinically relevant antiretroviral resistance is still controversial. Paired plasma HIV-1 RNA and whole blood DNA were compared in patients failing HAART to investigate if the additional knowledge of archived mutations could improve the selection of potentially active drugs. Seventy-three HIV-1-infected patients with first/second HAART failure were studied before starting a new regimen based on RNA genotyping. Follow-up data after a 12-week therapy were available. DNA genotyping was retrospectively performed on stored whole blood samples and mutational profiles were compared to those from RNA. The mean number of IAS pol mutations was si…
Mullarian-inhibiting substance reflects ovarian findings in women with polycystic ovary syndrome better than does inhibin-B
2005
Objective: To investigate Müllerian-inhibiting substance (MIS) levels in women with polycystic ovary syndrome (PCOS), as well as relationships to ovarian morphology, levels of inhibin B, and other reproductive hormones. Design: Prospective clinical study. Setting: Academic endocrinology centers in Palermo, Italy and New York. Patient(s): Forty-six women with PCOS, recruited on the basis of the classic criteria of chronic anovulation and hyperandrogenism, and 25 age-matched ovulatory controls. Intervention(s): Fasting blood was obtained in all subjects in the early follicular phase (days 5–6) after spontaneous or induced menses (in PCOS), and transvaginal ultrasounds were performed. Main Out…
Diversity and Evolution of the Phenazine Biosynthesis Pathway
2010
ABSTRACT Phenazines are versatile secondary metabolites of bacterial origin that function in biological control of plant pathogens and contribute to the ecological fitness and pathogenicity of the producing strains. In this study, we employed a collection of 94 strains having various geographic, environmental, and clinical origins to study the distribution and evolution of phenazine genes in members of the genera Pseudomonas , Burkholderia , Pectobacterium , Brevibacterium , and Streptomyces . Our results confirmed the diversity of phenazine producers and revealed that most of them appear to be soil-dwelling and/or plant-associated species. Genome analyses and comparisons of phylogenies inf…

Nueva inscripción latina en Algimia de Almonacid (Alto Palancia, Castellón): algunas notas sobre onomástica prerromana
1977
A mediados del pasado curso académico 1977/1978, Paco Gimeno, alumno de la Facultad de Geografía e Historia de la Universidad de Valencia, nos comunicó a un grupo de estudiantes de Prehistoria y Arqueología, la existencia en Algimia de Almonacid (hoja 640 del Mapa del Instituto Geográfico y Catastral, a escala 1:50.000) de una inscripción latina, al parecer inédita. Se trata de una inscripción aparecida hace ya varios años, al preparar para el cultivo de algarrobos una zona situada en la partida de Santa María Virgen de la Solana, en el límite con la del Puentecico, a la izquierda del camino de Alcudia de Veo, en la Parcela n.o 161, polígono 3, propiedad de Ignacio Cruzans Nebot, y que se c…
