Indicadores de actividad científica en investigadores singulares: perfil bibliométrico de Eduardo Primo Yúfera, expresidente del CSIC
2012
[EN] Eduardo Primo Yúfera was the founder of the Institute of Agrochemicals and Food Technology (IATA-CSIC) and was its director until being appointed president of the Spanish National Research Council. He is considered both patron and promoter of the fields of food science and technology and chemical ecology in Spain, as well as pioneer of the innovation system model (R+D+i). Throughout his long research career,which lasted 65 years, he published 291 scientifi c papers, with an average of 4.48 papers per year. Of these, 89.3 % were in collaboration with others: a total of 161 different coauthors. His efforts to disseminate science led him to create the Revista de Agroquímica y Tecnología d…
La meta e il percorso. Sguardi e menti di viaggiatori nella Grecia antica
2022
L’articolo indaga alcuni regimi scopici e ‘menti’ degli antichi viaggiatori greci. Esso prende in considerazione: gli sguardi omerici, vari ma tutti legati tra loro dall’essere rivolti verso specifici punti, singoli o, nel quadro di una conoscenza cumulativa, ‘sommati’ gli uni agli altri; il modo di guardare del sapiente, che riflette sulla relazione tra tutto ciò che vede durante il percorso; quello del turista, che concentra l’osservazione sulla meta scelta – a volte anche soltanto per potere raccontare di esservi stato; quello del lettore, che ‘si sposta’ attraverso i libri di viaggio o di storia; e altri sguardi che costituiscono intrecci o variazioni di quelli precedenti, presentandosi…
Is a seminar based on student-created screen capture videos a meaningful way of learning?
2008
We ran a problem-based seminar with screen capture videos. The students worked in small groups of two or three students or they completed the coursework individually. In this seminar the students had a workspace in the Optima environment for publishing their coursework videos. At the final phase of the course the students were expected to familiarize themselves with the presentations of other groups. In this paper we analyze the benefit of our problem-based coursework on the web by comparing the different phases of it. After each phase the students were expected to analyze the benefit of it for their learning. peerReviewed
Screen-based activities and physical complaints among adolescents from the Nordic countries
2010
BACKGROUND: A positive association between time spent on sedentary screen-based activities and physical complaints has been reported, but the cumulative association between different types of screen-based activities and physical complaints has not been examined thoroughly. METHODS: The cross-sectional association between screen-based activity and physical complaints (backache and headache) among students was examined in a sample of 31022 adolescents from Denmark, Sweden, Norway, Finland, Iceland and Greenland, as part of the Health behaviour in school-aged children 2005/06 (HBSC) study. Daily hours spent on screen-based activities and levels of physical complaints were assessed using self-r…
Design and Characterization of Effective Ag, Pt and AgPt Nanoparticles to H₂O₂ Electrosensing from Scrapped Printed Electrodes.
2019
The use of disposable screen-printed electrodes (SPEs) has extraordinarily grown in the last years. In this paper, conductive inks from scrapped SPEs were removed by acid leaching, providing high value feedstocks suitable for the electrochemical deposition of Ag, Pt and Ag core-Pt shell-like bimetallic (AgPt) nanoparticles, onto screen-printed carbon electrodes (ML@SPCEs, M = Ag, Pt or AgPt, L = metal nanoparticles from leaching solutions). ML@SPCEs were characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The results were compared to those obtained when metal nanoparticles were synthesised using standard solutions of metal salts (MS@…
Evaluation of oleander accessions for resistance to Pseudomonas savastanoi pv. nerii
2006
Nine oleander accessions were evaluated for resistance to Pseudomonas savastanoi pv. nerii, causal agent of the oleander knot disease. None of the accessions was resistant when tested with three bacterial strains of different virulence, but they varied significantly in the severity of symptoms induced by these strains. The most susceptible accessions "Dark Salmon" (dark salmon flower) showed deformation of stems, leaves and seed pods and secondary knots on aerial parts, whereas the least susceptible one "White" (white flower), inoculated with the least virulent strain, showed neither localized knots at the inoculation point nor secondary symptoms. In this study an in vitro test, based on pr…
Could a Behavioral Model Explain Adherence to Second-Level Colonoscopy for Colon Cancer Screening? Results of a Cross-Sectional Study of the Palermo …
2022
According to Italian Essential Levels of Assistance (ELA), a colonoscopy is strongly recommended after a positive fecal occult blood test (FOBT) due to its effectiveness in early colorectal cancer detection. Despite the evidence, the Palermo province population (Italy), after a positive FOBT, have a lower colonoscopy adherence compared to Italian standards. This cross-sectional study analyzed patients’ perceptions of colonoscopy procedures to understand the reasons for non-adherence. Patients with a positive FOBT who did not undergo a colonoscopy within the national organized screening program were administered a telephone interview based on the Health Belief Model (HBM) questionnaire. The …
Detección de la condición TDAH en niños/as de la Provincia de Cuenca mediante la Escala Magallanes de Detección de Déficit de Atención (EMA-DDA).
2015
Actualmente nuestra sociedad sigue empleando el término “niño hiperactivo” como síntoma de un trastorno, indicio de posible TDAH, hecho que lleva a confusión a muchos padres y maestros. Es de suma importancia que aclaremos o remarquemos, a nivel social e incluso profesional, la diferencia entre niños inquietos, ansiosos o inadaptados emocionales y socialmente de aquellos que presentan un comportamiento y funcionamiento cognitivo que puede considerarse patológico, debido a la elevada intensidad de una sintomatología que puede generar problemas de adaptación, (Orjales Villar, I. 2003: Trastorno por déficit de atención/ hiperactividad TDAH), para poder ofrecerles una atención educativa y socia…
Effect of different packaging methods on the free amino acid profiles of the deep-water rose shrimp (Parapenaeus longirostris) during frozen storage
2022
The composition of free amino acids (FAAs) in seafood products contributes to characterizing their flavor, as well as freshness and quality during storage. Deep-water rose shrimps (Parapenaues longirostris, Lucas, 1846) (DWRS) are being increasingly harvested in the Mediterranean Sea, and the captured specimens are quickly frozen onboard fishing trawlers to preserve freshness and post-harvest quality. Here, we quantified the FAA profiles of DWRS packaged using five methods: (1) 100% N2; (2) vacuum; (3) 50% N2 + 50% CO2; (4) commercial anhydrous sodium sulfite; and (5) air (control). All samples were quickly frozen at −35°C and stored for 12 months at −18°C. Arginine (661 mg/100 g), proline …
Innovative In Situ and Ex Situ Conservation Strategies of the Madonie Fir Abies nebrodensis
2022
Abies nebrodensis (Lojac.) Mattei is an endemic species of the north-west of Sicily located in an 84 ha area in the Madonie Regional park. The current population is limited to 30 relic adult trees and a fluctuating number of juveniles of natural regeneration. The species is defined as “Critically Endangered” in the Italian list of threatened plants and is classified as CR-D in the 2000 IUCN Red List of Threatened Species. This article reports the key action undertaken by the LIFE4FIR project aimed at preserving A. nebrodensis, and the results obtained so far in three years of activity. OpenArrays SNPs genotyping revealed a high rate of inbreeding in the natural population and that the adult…
