Relationship between Training Load Management and Immunoglobulin A to Avoid Immunosuppression after Soccer Training and Competition: A Theoretical Fr…

2021

Immunoglobulin A (IgA), which is the main effector against upper respiratory tract viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been related to training load management. The aim of this systematic review was to establish the relationship between training load and salivary IgA based on current evidence in order to avoid immunosuppression after exercise and players´ vulnerability to virus contagion. A systematic review of relevant articles was carried out using two electronic databases (PubMed and Web of Science) until 19 May 2021. From a total of 127 studies initially found, 23 were included in the qualitative synthesis. These studies were clustered depen…

2021

Immunoglobulin A (IgA), which is the first line of defense against upper respiratory tract viruses, has been related with training load management. This article aimed to systematically identify and summarize (1) the studies that have found a relationship between training load and salivary IgA in team sports, and (2) the studies that have highlighted a relationship between IgA and upper respiratory tract infection (URTI) in team sports. A systematic review of relevant articles was carried out using two electronic databases (PubMed and WoK) until 3 October 2020. From a total of 174 studies initially found, 24 were included in the qualitative synthesis. This systematic review confirmed that lo…

Lead Nanowires for Microaccumulators Obtained Through Indirect Electrochemical Template Deposition

2010

Metallic lead nanowires were deposited within pores of commercial anodic alumina membranes having an average pore diameter of 210 nm. "Direct" electrodeposition was attempted from 0.1 M Pb(NO 3 ) 2 aqueous solution with a variable concentration of H 3 BO 3 as a chelating agent, but it gave unsatisfactory results. An "indirect" two-step deposition procedure was then adopted, consisting of the anodic electrodeposition of α-PbO 2 nanowires, followed by their in situ reduction to metallic lead. Both these processes occurred at a high rate so that the indirect method led to a complete template pore filling with pure polycrystalline Pb in short times and with a high current efficiency.

Brancati su Pirandello e il pirandellismo

2019

Nel romanzo breve "Sogno di un valzer" uscito a puntate su “Quadrivio”, dal 5 giugno al 14 agosto 1938, Vitaliano Brancati mette in scena, tra osservazione dei luoghi e rilevamento di costume, un’umanità fuori misura, continuamente in bilico tra realtà e sogno. A Caltanissetta (Nissa) la città nel cui Istituto magistrale lo scrittore, voltate le spalle alla Roma fascista, è venuto a insegnare, personaggi non appariscenti, insignificanti, che tuttavia covano desideri, si arrovellano in domande metafisiche. Prende così forma il leitmotiv delle critica al pirandellismo che più volte con ironia sottile affiora negli scritti brancatiani. Il saggio mostra come esso si intrecci con la comicità sul…

In the short novel "Sogno di un valzer" published on "Quadrivio" from 5 June to 14 August 1938 Vitaliano Brancati enacts between observation of places and survey of customs a world beyond measure constantly hovering between reality and dream. In Caltanissetta (Nissa) the city in which the writer is the magistral institute turned his back on fascist Rome he came to teach unobtrusive insignificant characters who nevertheless covet desires racking their brains in metaphysical questions. Thus the leitmotiv of the critics of pirandellism takes shape which often with subtle irony emerges in the Brancatian writings. The essay shows how it intertwines with the sulphurous comedy of the writer of Don Giovanni in Sicilia who tracing a particular topography of the island supported by inner relief leads his analysis of eccentric behaviors and of the aberrations of the mind in which the trivialized Pirandellian thought ends to become an explosive element.

"Table 7" of "$\rm \Lambda_{c}^{+}$ production and baryon-to-meson ratios in pp and p-Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV at the LHC"

2021

$p_{\rm {T}}$-integrated prompt $\Lambda_{\rm {c}}^{+}$ baryon cross section in pp collisions at $\sqrt{s} = 5.02$ TeV in the rapidity interval $|y|<0.5$, and in p-Pb collisions at $\sqrt{s_{\rm {NN}}} = 5.02$ TeV in the rapidity interval $-0.96 \lt y \lt 0.04$. First column: The $p_{\rm {T}}$-integrated cross section in the visible (measured) $p_{\rm {T}}$ region, which in pp collisions is $1 \lt p_{\rm T} \lt 12$ GeV/c and in p-Pb collisions is $1 \lt p_{\rm T} \lt 24$ GeV/c. The second (sys) error is from the luminosity uncertainty. Second column: The $p_{\rm {T}}$-integrated cross section extrapolated to all $p_{\rm {T}}$. The second (sys) error is from the luminosity uncertainty and…
