Posverdad, o la narración del procés catalán desde el exterior: BBC, DW y RT
2019
Con el procés independentista de Cataluña como marco, compararemos el tratamiento periodístico que recibe el fenómeno en tres medios de comunicación extranjeros, reflejado en su difusión a través de la red social Facebook. BBC, DW y RT son corporaciones financiadas públicamente por gobiernos ajenos a priori a la problemática social y política generada sobre el debate separatista. Aun así, uno de ellos, RT, ha sido acusado públicamente de actuar directamente bajo la influencia de las directrices de política exterior del Kremlin, y de cometer injerencias a favor de los independentistas. Desde una perspectiva cuantitativa y cualitativa, analizamos los posts difundidos por estos medios durante …
Trato del Telediario público español a temas y líderes políticos (2014-2021)
2021
Ante la ausencia o retraso e incompletitud de registros de lo emitido en TV pública, se ofrece un estudio único, por su alcance (desde 2014 a 2021) y su novedoso método, sobre el Telediario de La 1 de Televisión Española. Se usa la herramienta Verba de la Fundación Civio, cuyo afán por la transparencia es presentado en la introducción, además de tratar la influencia de los medios en partidos políticos y agenda. El objetivo principal es evaluar dos tipos de elementos: 30 nombres de líderes políticos y 30 expresiones con incidencia política (los 15 principales problemas citados por la ciudadanía en el último CIS y otros 15 vinculados). El modelo se centra en las palabras pronunciadas y faltar…
Activated Cashew Carbon-Manganese Oxide Based Electrodes for Supercapacitor Applications
2023
The current global energy challenge which affects most developing countries in particular, is of major source of concern today. The availability of less expensive techniques of storing excess generated energy is critical to the success of the renewable energy roadmaps implementation. In this study, hydrothermal and chemical leaching methods have been used to synthesize MnO2 nanoparticles using KMnO4 and MnSO4 as precursors at 140 °C and from natural local manganese ore. Activated Carbon (ACF) have also been produced from agricultural Cashew biomass waste, through a physical carbonization and KOH activation process using temperatures of 700 °C – 900 °C for periods between 1-2 hours. The as-p…
Protective Effects of Foam Rolling against Inflammation and Notexin Induced Muscle Damage in Rats
2019
It is known that high-intensity exercise can cause inflammation and damage in muscle tissue, and in recent years, physical therapists and fitness professionals have begun to use foam rolling as a recovery method to improve performance. Despite the lack of basic science studies to support or refute the efficacy of foam rolling, the technique is very widely used in the sports world. In this respect, we investigated whether foam rolling could attenuate muscle damage and inflammation. Female Wistar rats were assigned to control (C), foam rolling (FR), notexin without foam rolling (N) and notexin with foam rolling (NFR) groups. A 4.5 x 2 cm foam roller was used to massage their hind legs (two 60…
Effectiveness of Physical Therapy in Patients with Tension-type Headache: Literature Review
2014
Background: Tension-type headache (TTH) is a disease with a great incidence on quality of life and with a significant socioeconomic impact. Objectives: The aim of this review is to determine the effectiveness of physical therapy by using manual therapy (MT) for the relief of TTH. Data sources: A review was done identifying randomized controlled trials through searches in MEDLINE, PEDro, Cochrane and CINAHL (January 2002 – April 2012). Study selection: English-language studies, with adult patients and number of subjects not under 11, diagnosed with episodic tension-type headache (ETTH) and chronic tension-type headache (CTTH) were included. Data extraction: Initial search was undertaken with…
La nutrizione proteico/aminoacidica gold standard nel trattamento dell’obesità e del sovrappeso in soggetti con alterazioni endocrino-metaboliche

La nutrizione proteico/aminoacidica gold standard nel trattamento dell’obesità e del sovrappeso in soggetti con alterazioni endocrino- metaboliche Matteo Tutino1, Giuseppe Morici1, Antonella Milito1, Vittorio Calabrese2. 1Università di Palermo, Dipartimento di Biomedicina Sperimentale e Neuroscienze Cliniche - 2Università di Catania, Dipartimento di Biochimica Clinica La nutrizione proteico/aminoacidica ed enterale proteica viene da molti considerata come un’alimentazione impropria, poiché i risultati non sono costanti; infatti non tutti i pazienti perdono peso come dovrebbero ed inoltre molti pazienti che hanno perso peso recuperano i chili persi. Gli Autori hanno voluto testare l’efficaci…
MODELLI DI STUDIO DI BIOMARKERS PER LA VALUTAZIONE DEL RISCHIO DI CONTAMINAZIONE DA NANOPARTICELLE D’ARGENTO NEL SUOLO (PROGETTO INESE)
2013
Il progetto “Impact of Nanoparticles in Environmental Sustainability and Ecotoxicity” (INESE), finanziato dall’Istituto Italiano di Tecnologia (IIT), ha studiato gli effetti delle nanoparticelle (NPs) ingegnerizzate su diversi ecosistemi (acquatici e terrestri), proponendo differenti sistemi biologici di studio (piante acquatiche, ricci di mare, organismi del suolo, pomodoro-impollinatore, ecc). In particolare l’UO dell’Università di Bologna ha focalizzato l’attenzione sullo studio dei modelli di interazione tra particelle di suolo, microorganismi (biomassa microbica), invertebrati (Lumbricus rubellus) e pianta (Solanum lycopersicum). In questa sede verranno riportati i risultati ottenuti d…
Odd-odd neutron-rich rhodium isotopes studied with the double Penning trap JYFLTRAP
2022
Precision mass measurements of neutron-rich rhodium isotopes have been performed at the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. We report results on ground- and isomeric-state masses in $^{110,112,114,116,118}$Rh and the very first mass measurement of $^{120}$Rh. The isomeric states were separated and measured for the first time using the phase-imaging ion-cyclotron-resonance (PI-ICR) technique. For $^{112}$Rh, we also report new half-lives for both the ground state and the isomer. The results are compared to theoretical predictions using the BSkG1 mass model and discussed in terms of triaxial deformation.
High-precision electron-capture Q value measurement of 111In for electron-neutrino mass determination
2022
A precise determination of the ground state $^{111}$In ($9/2^+$) electron capture to ground state of $^{111}$Cd ($1/2^+$) $Q$ value has been performed utilizing the double Penning trap mass spectrometer, JYFLTRAP. A value of 857.63(17) keV was obtained, which is nearly a factor of 20 more precise than the value extracted from the Atomic Mass Evaluation 2020 (AME2020). The high-precision electron-capture $Q$ value measurement along with the nuclear energy level data of 866.60(6) keV, 864.8(3) keV, 855.6(10) keV, and 853.94(7) keV for $^{111}$Cd was used to determine whether the four states are energetically allowed for a potential ultra-low $Q$-value $\beta^{}$ decay or electron-capture deca…
Study of radial motion phase advance during motion excitations in a Penning trap and accuracy of JYFLTRAP mass spectrometer
2021
Phase-imaging ion-cyclotron-resonance technique has been implemented at the Penning-trap mass spectrometer JYFLTRAP and is routinely employed for mass measurements of stable and short-lived nuclides produced at IGISOL facility. Systematic uncertainties that impose limitations on the accuracy of measurements are discussed. It was found out that the phase evolution of the radial motion of ions in a Penning trap during the application of radio-frequency fields leads to a systematic cyclotron frequency shift when more than one ion species is present in the trap during the cyclotron frequency measurement. An analytic expression was derived to correctly account for the shift. Cross-reference mass…
