Trasmissione del calore nei letti fluidizzati con liquidi
2007
Lo studio dei fenomeni relativi all’idrodinamica ed allo scambio termico nei letti fluidizzati è di grande interesse nell’Energetica industriale. Infatti è necessaria la loro comprensione per proporre modelli affidabili ai fini della progettazione e della simulazione del funzionamento delle tante apparecchiature nelle quali essi si manifestano. In molti processi industriali i contatti e le interazioni tra fluidi, siano essi liquidi o gas, e particolati solidi consentono una grande varietà di utili applicazioni. Si tratta del campo dell’ingegneria della fluidizzazione, che ha suscitato un ampio interesse fin dalla realizzazione, durante la Seconda Guerra Mondiale, dei reattori a letto fluido…
Investigation on the stability of dispersion of zirconia nanoparticles prepared by microwave- hydrothermal synthesis
2005
Difficulties in reproducing the performances of nanoparticles dispersions are obstructive for the progress of the nanotechnology. A plausible reason for this variability is the lack of the control of the stability as well as the dimensions of the nanoparticles in the dispersions. In this work we report results of investigations on the stability of zirconia nanoparticles in aqueous medium, monitoring nanoparticles sizes by means of Transmission Electron Microscopy (TEM), Dynamic Light Scattering (DLS). Nanocrystalline zirconia powders, prepared by microwave-hydrothermal synthesis, were determined to be 6-8 nm in size by TEM observations. By using DLS technique the as-prepared dispersions wit…
Different Measurement Setup Configurations for Space Charge test in Mini Cable Specimens with the PEA Method
2019
Under DC stress, the space charge accumulation is believed one of the most responsible of dielectrics ageing. For this reason, due to the increase of the HVDC transmission, a recommendation has been proposed. The latter want to introduce the space charge measure, with the PEA method, in cable specimens during the prequalification or type tests. Considering the several issues related to this kind of measures the aim of the proposed work is find a measurement setup for mini cable specimens which is able to provide a clear and clean space charge profile. Therefore, different tests have been made in this work. In particular, the length of the cable specimen, the width of the pulse electrodes, a…
Brain Opioid Activity and Oxidative Injury: Different Molecular Scenarios Connecting Celiac Disease and Autistic Spectrum Disorder
2020
Celiac Disease (CD) is an immune-mediated disease triggered by the ingestion of wheat gliadin and related prolamins from other cereals, such as barley and rye. Immunity against these cereal-derived proteins is mediated by pro-inflammatory cytokines produced by both innate and adaptive system response in individuals unable to adequately digest them. Peptides generated in this condition are absorbed across the gut barrier, which in these patients is characterized by the deregulation of its permeability. Here, we discuss a possible correlation between CD and Autistic Spectrum Disorder (ASD) pathogenesis. ASD can be induced by an excessive and inappropriate brain opioid activity during the neon…
Enhancing the performance of HSDPA communication with multipoint transmission techniques
2015
The evolution of mobile phones, tablets and other mobile communication devices has led to a significant increase in the amount of data delivered over mobile networks. In order to satisfy the climbing data rate demands of customers, existing mobile broadband networks are being expanded with new features that allow ubiquitous and consistent networking experience. This research presents three multipoint transmission techniques for Wideband Code Division Multiple Access (WCDMA) based High-Speed Downlink Packet Access (HSDPA) communication protocol. Multiflow, High-Speed Single-Frequency Network (HS-SFN) and Multipoint-to-Point Single-Frequency Network (M2P-SFN) enable transmission of user-dedicat…
Przeciw mitom - o mrocznych stronach macierzyństwa w powieści Slavenki Drakulić - "Optužena"
2017
Starting with Jean Jacob Rousseau’s, Sigmund Freud’s and feminists’ of the second wave views on matemity, the paper shows Slavenka Drakulić’s ideas presented in her novel Optužena. The Croatian author rejects the myth of matemal love by writing about yiolence against the child and pathology in the mother-daughter relationship. The problem of transgenerational transmission of trauma is shown in an interesting literary way and it is really innovatory.
O materinstvu na drugi način - prećutane strane materinstva u romanu "Optužena" Slavenke Drakulić
2017
Slavenka Drakulić is a Croatian journalist and writer, known as a feminist who writes about the problems in women’s lives. In the novel Optužena (2012), she demonstrates in an interesting, artistic way the less known questions of motherhood, often ignored and tabooed in social discourse. It is known that starting from Jean-Jacques Rousseau’s ideas about maternity, it has been idealized and used in order to constrain women within the patriarchal system, by identifying them primarily as mothers. The concepts of Sigmund Freud, who believed maternity and maternal love to be natural and appropriate for every “standard” woman, contributed to turning into taboos some pathologies connected with mat…
GUANOSINE EFFECTS ON THE MOTOR ACTIVITY OF THE MOUSE STOMACH
2012
Guanine-based purines are part of the purinergic system and recently have been shown to act as neuromodulators, interfering with acetylcholine release by enteric neurons in mouse colon. Due to the pivotal role played by enteric neurons in the control of gastrointestinal motility, the aim of the present study was to verify whether guanosine may affect gastric emptying and the mechanical tone, detected in vitro as changes in intraluminal pressure, of the isolated mouse stomach. Guanosine induced a TTX-insensitive concentration-dependent relaxation of isolated stomach, which at the maximal concentration tested (1 mM), reached about 60% of the relaxation induced by 1 mM isoproterenol. The inhib…
Conocimiento, traza e ingenio en la arquitectura valenciana del siglo XV
2012
In the last decades historiography of gothic architecture in the Crown of Aragon has focused on buildings monographs, documentary research and technical change in stone building. On the other hand, historians of technology have given special attention to the issue of innovation and its diffusion in the late Middle Ages, considering building techniques as a particular field of research. This essay studies transmission of technical knowledge in building trades in order to explain architectural changes in an outstanding environment of innovation such as the kingdom of Valencia in the 14th and 15th centuries, especially from 1430 onwards. Having account of previous research and some cases of st…
