A novel device for assessing the health risk caused by hand-arm vibrations in olives harvesting
2012
The mechanization of olive harvesting is very important both to reduce the costs of production and to assure the oil quality because the manual harvest does not allow to operate at the right time and also need a long period to be completed. The use of portable shakers, that are spreading more than others typologies, can give a solution to the problem. However, the use of such equipment may involve risk of exposure to hand-transmitted vibration. The aim of this study was to assess the level of exposure to hand-arm vibration of the operators using portable shakers (reference standards UNI EN ISO 5349-1:2004, Italian Low Decree 81/2008). The research presented here concerns the definition of a…
Tenapanor for the treatment of irritable bowel syndrome with constipation.
2020
Introduction: Irritable bowel syndrome with constipation is associated with higher rates of functional impairment, as compared to other subtypes of the syndrome. Conventional laxative-based pharmacologic therapy of IBS-C, which is mostly symptom-based, is often unsatisfactory. Tenapanor represents a first-in-class orally available inhibitor of NHE3, which is minimally absorbed in the GI tract, what constitutes a significant therapeutic benefit, as it may act on the drug target. Areas covered: Aim of this article is to sum up the evidences about pharmacodynamics and pharmacokinetics of tenapanor, focusing on animal models and in vitro studies, but also discuss clinical trials on tenapanor's …
Systematic review and meta-analysis of the efficacy and safety of minocycline in schizophrenia
2017
ObjectiveOur aim was to perform an updated systematic review and meta-analysis on the efficacy and safety of adjunctive minocycline as a treatment of schizophrenia.MethodsWe conducted a PubMed/Scopus database search from inception to 3 February 2016 for randomized, placebo-controlled trials (RCTs), open non-randomized studies, and case reports/series evaluating minocycline in patients with schizophrenia. Random-effects meta-analysis of positive, negative, depressive, and cognitive symptom rating scales, discontinuation and adverse effects rates calculating standardized mean difference (SMD), and risk ratios±95% confidence intervals (CI95%) were calculated.ResultsSix RCTs were eligible (mino…

Method development for determination and recovery of rare earth elements from industrial fly ash
2014
Rare earth elements (REE) are important in numerous high technology applications and in addition their supply risk is high, which gives rise to studying new sources for rare earth elements. Rare earth element concentrations in industrial fly ash samples collected from Finnish power plants, using a mixture of peat and biomass as a fuel, have been determined. Two sample pre-treatment methods, ultrasound- and microwave-assisted acid digestions, have been applied to fly ash samples. Measurement conditions for inductively coupled plasma-optical emission spectrometry (ICP–OES) have been optimized to reach robust plasma conditions and the reliability of the analysis has been investigated by using …
Interactions arôme saveur texture
2012
L’acceptabilité des aliments par le consommateur dépend, en partie, de leurs propriétés sensorielles. La perception de l’arôme et de la saveur est principalement liée à la présence de molécules odorantes ou sapides. Néanmoins la perception de l’arôme peut être modifiée par la présence de certaines saveurs et réciproquement, par l’existence d’interactions perceptives. De même la texture de l’aliment va influencer la perception de son arôme et de sa saveur, principalement par l’existence d’interactions physicochimiques entre les molécules au sein de l’aliment ou par des modifications de la libération des molécules odorantes et sapides lors de la mastication. De ce fait, faire varier l’une de …
Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide
2018
The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…
Statue lignee nel Settecento nelle chiese di Ficarazzi: aggiunte alla produzione di Filippo Quattrocchi e della sua bottega
2020
Il contributo esamina quattro statue lignee, due delle quali inedite, custodite nelle chiese di Ficarazzi, piccolo centro delle province di Palermo. Si tratta di sculture realizzate tra la fine del Settecento e i primi decenni del secolo successivo, che vengono ricondotte per la prima volta al noto Filippo Quattrocchi e alla sua bottega, in particolare al figlio Francesco. Tra queste si cita l’Immacolata Concezione della chiesa di San Girolamo che, restaurata di recente, afferisce ad un prototipo iconografico divulgato dal pittore Vito D’Anna e dallo scultore Ignazio Marabitti su influsso di modelli accademici romani considerato che entrambi gli artisti lavorarono nella Città Eterna. The co…
Medición del gasto energético en una muestra de escolares adolescentes valencianos mediante acelerometría
2011
Este estudio representa el trabajo más reciente de los desarrollados dentro de la línea de investigación de ‘Actividad física y salud’ que mantiene el grupo en el que se sitúa este estudio: Unidad de Investigación de Teoría y Pedagogía de la Actividad Física y el Deporte. Esta investigación se ha realizado conjuntamente entre la Universidad de Valencia y el Instituto de Educación Secundaria Nº1 de Cheste, Valencia. Dicho Instituto tiene la peculiaridad de albergar a estudiantes pertenecientes al Plan de Especialización Deportiva (PED). El objetivo principal es conocer el gasto energético tanto de los adolescentes pertenecientes al PED como los que no, en el ciclo educativo al que pertenecen…
