Valoración patrimonial de los yacimientos del Mioceno inferior del Barranco de Campisano de la Cuenca de Ribesalbes-Alcora (Araia d'Alcora, Castelló,…
2019
En el presente trabajo se realiza una valoración patrimonial del conjunto de yacimientos del Mioceno inferior del barranco de Campisano (cuenca de Ribesalbes-Alcora). Los resultados obtenidos al calcular los parámetros según la metodología del Inventario Español de Lugares de Interés Geológico (IELIG) ponen de manifi esto el alto valor científi co y didáctico de la zona, así como un valor turístico y recreativo medio. El riesgo de degradación es medio, por lo que debería ser tenido en cuenta para la protección de los yacimientos a corto plazo. En consonancia con estos datos, se propone la consideración de los yacimientos como LIG (Lugar de Interés Geológico) y su inclusión en el IELIG. In t…
Fasciola hepatica phenotypic characterization in Andean human endemic areas: Valley versus altiplanic patterns analysed in liver flukes from sheep fr…
2011
Fascioliasis is a zoonotic parasitic disease caused by Fasciola hepatica and Fasciola gigantica. Of both species, F. hepatica is the only one described in the Americas, mainly transmitted by lymnaeid snail vectors of the Galba/. Fossaria group. Human fascioliasis endemic areas are mainly located in high altitude areas of Andean countries. Given the necessity to characterize F. hepatica populations involved, the phenotypic features of fasciolid adults infecting sheep present in human fascioliasis endemic areas were analysed in the Cajamarca Valley and Mantaro Valley (valley transmission patterns) and the northern Bolivian Altiplano (altiplanic transmission pattern). A computer image analysis…
Manipulating the alpha level cannot cure significance testing
2018
We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple in…
Parents or Peers? Predictors of Prosocial Behavior and Aggression: A Longitudinal Study
2019
The aim of this longitudinal study was to determine the associations among peer attachment, warmth from the mother and father, strict control by the mother and father, prosocial behavior, and physical and verbal aggression in adolescence. Few longitudinal studies have examined how peer attachment and parenting styles of the mother and father relate to prosocial behavior and aggression. Participants were 192 boys and 255 girls (M = 14.70 years; SD = 0.68) in wave 1. In the study participated 11 schools. For three successive years, participants reported on their fathers’ and mothers’ warmth and strict control, peer attachment, prosocial behavior, and aggression. Structural equations modeling …
Chemical and photochemical properties of chloroharmine derivatives in aqueous solutions
2015
Thermal and photochemical stability (ΦR), room temperature UV-vis absorption and fluorescence spectra, fluorescence quantum yields (ΦF) and lifetimes (τF), quantum yields of hydrogen peroxide (ΦH2O2) and singlet oxygen (ΦΔ) production, and triplet lifetimes (τT) have been obtained for the neutral and protonated forms of 6-chloroharmine, 8-chloroharmine and 6,8-dichloroharmine, in aqueous media. When it was possible, the effect of pH and oxygen concentration was evaluated. The nature of electronic transitions of protonated and neutral species of the three investigated chloroharmines was established using Time-Dependent Density Functional Theory (TD-DFT) calculations. The impact of all the fo…
Analysis of Business Elite Networks and Revolving Doors in Mexico : Cartography of a Public-Private Ruling Class
2020
La presente investigación mapea las redes de las élites empresariales y políticas en México para comprender la organización social y la capacidad de influencia de las élites mexicanas, y abrir vías de investigación sobre las élites de poder en México. En primer lugar, se realiza un estudio de la cohesión interna de las élites empresariales mediante un análisis de redes de interlocking directorates y enlaces de propiedad. En segundo lugar, se examinan varios casos de puertas giratorias mediante un análisis prosopográfico de biografías y trayectorias. Los resultados revelan que las élites empresariales mexicanas están cohesionadas y que existe un grupo de individuos que fluctúan entre el sect…
All that Glitters is not Green
2012
The painter, carrying his easel, walks leisurely across the meadow that extends up to the limits of the summer sky. Under a chestnut tree he prepares his palette and his colors, then stretches and smiles. He is wearing a cotton shirt and slacks; a straw hat covers his curly hair. He walks barefoot because he likes the feel of the grass under his feet. This painter loves nature; he loves nature as an artist and as a scientist. This painter is a nuclear physicist, and his job consists in harnessing the elementary power of the atom, the one that makes the stars glow, in order to generate the power and hydrogen his town uses.
First report of Tomato leaf curl Sinaloa virus infecting tomato crops in Panama
2015
In April 2011 and September 2012, virus-like symptoms were observed in open field- and greenhouse-grown tomato crops (Solanum lycopersicum) in Chiriquí, the westernmost province of Panama. Samples from symptom-bearing plants (127 in all) were collected and tested for the presence of begomoviruses by polymerase chain reaction (PCR) assays with sets of degenerated primers designed to amplify parts of the DNA-A and DNA-B components (Rojas et al., 1993; Table 1). Products of the expected sizes, obtained with both DNA-A- and DNA-B-specific primers for 49 samples, suggested infection with New World bipartite begomoviruses. This corresponds to an incidence of 26% (8 plants) in open field, and 43% …
Third family of compact stars within a nonlocal chiral quark model equation of state
2019
A class of hybrid compact star equations of state is investigated that joins by a Maxwell construction a low-density phase of hadronic matter, modeled by a relativistic mean-field approach with excluded nucleon volume, with a high-density phase of color superconducting two-flavor quark matter, described within a nonlocal covariant chiral quark model. It is found that the occurrence of a stable branch of hybrid compact stars requires a nonvanishing vector meson coupling in the quark model that exceeds a minimal value which depends on the presence of a diquark condensate. It is shown that these hybrid stars do not form a third family disconnected from the second family of ordinary neutron sta…
Nuclear and partonic dynamics in the EMC effect
2013
It has been recently confirmed that the magnitude of the EMC effect measured in the electron deep inelastic scattering is linearly related to the short-range correlation scaling factor obtained from electron inclusive scattering. By using a x-rescaling approach we are able to understand the interplay between the quark-gluon and hadronic degrees of freedom in the discussion of the EMC effect.
