Experimental tests about the cooling/freezing of the molten salts in the receiver tubes of a solar power plant with parabolic trough
In 2003 ENEA realized the PCS experimental Facility at Casaccia Research Centre (Rome, Italy), in order to test in real operating conditions the components of a parabolic trough solar plant, and to evaluate the technical feasibility of using the solar molten salts mixture (60% NaNO3, 40% KNO3, melting point 220÷240°C) in such a type of plant. ENEA also had the need to assess the behaviour of the solar receiver tubes during abnormal operating situations (wrong operation, pump block, power failure, etc.), when a block of the circulation of the molten salts may occur and cause the cooling or, worse, the freezing of the salts mixture inside the pipes. Some experimental tests have been performed, aimed to examine what happens in such a cases. In fact, without quick maneuvers to restart the circulation of the molten salts or to readily empty the receiver tubes, the molten salts contained in them may cool down to temperatures near/below the solidification. In this report are shown the results of the experimental tests carried out on the receiver tubes of the PCS Facility by cooling the process fluid down to temperatures near or below its freezing point. The tests show that the solidification of the salts does not damage the components of the plant but it is manageable and reversible, provided you apply the correct procedures. © 2017 Author(s)

Emphania erichsoni Ahrens & Fabrizi 2008, n. sp.
Emphania erichsoni n. sp. TYPE MATERIAL. — Holotype: ♂ " Madagascar A. Mocquervs 99-96." (BMNH). ETYMOLOGY. — The new species is named after W. F. Erichson who established the genus Emphania in 1847. DESCRIPTION OF HOLOTYPE Length: 6.9 mm; length of elytra: 4.7 mm; width: 4.5 mm. Body surface brown with greenish shine. Head and antenna as in E. metallica; clypeal surface flat; eyes, ratio of diameter/interocular width: 0.57; antennomeres 3-5 unfused. Pronotum and scutellum as in E. metallica; basal marginal line of pronotum lacking. Elytra as in E. metallica, without convex semicircular declivity; intervals with fine and dense punctures that are superficially slightly longitudinally impressed. Metacoxa as in E. metallica, posteriorly produced forming a moderately sharp tooth. Ratio of length of metepisternum/metacoxa:1/2.2. Pygidium as in E. metallica. Legs as in E. metallica. Posterior legs lacking in the holotype. Aedeagus: Figure 2 J-L. B C EE H I REMARKS The new species differs from E. metallica in the smaller body size, the lacking posterior elytral declivity, the longitudinally impressed elytral punctures, the unfused antennomeres 3-5, and the shape of male genitalia having the parameres more elongate and weakly curved interiorly, without an apical hook.Published as part of Ahrens, Dirk & Fabrizi, Silvia, 2008, A taxonomic revision of the Malagasy genus Emphania Erichson, 1847 (Insecta, Coleoptera, Scarabaeidae, Sericini), pp. 917-927 in Zoosystema 30 (4) on pages 924-926, DOI: 10.5281/zenodo.452585

Emphania ranomafanae Ahrens & Fabrizi 2008, n. sp.
Emphania ranomafanae n. sp. TYPE MATERIAL. — Holotype: ♂ " Madagascar: Fianarantsoa: Ranomafana National Park, Talatakely, research 1998 V. F. Lee, K. J. Ribardo, leg. Calif. Acad. Sci. Collection / Casent 8006559" (CASC). Paratype: 1 ♀ " Madagascar: Fianarantsoa: Ranomafana National Park, Talatakely, research 1998 V. F. Lee, K. J. Ribardo, leg. Calif. Acad. Sci. Collection/Casent 8006560" (CASC). ETYMOLOGY. — The new species is named after its occurrence in the Ranomafana National Park. DESCRIPTION OF HOLOTYPE Length: 8.5 mm; length of elytra: 5.8 mm; width: 5.3 mm. Body surface brown with reddish to greenish shine. Labroclypeus and antenna as in E. metallica; eyes, ratio of diameter/interocular width: 0.53; antennomeres 3-5 not fused. Pronotum, scutellum and elytra as in E. metallica. Metacoxa and pygidium as in E. metallica. Ratio of length of metepisternum/metacoxa: 1/1.87. Legs as in E. metallica; ratio metatibial width/length: 1/4.25, medial face of metatibia with one or two punctures beside the dorsal margin. Aedeagus: Figure 2 P-R. VARIATION No variation in body measurements observed.Colour varies from blackish green to reddish purple. The female has the antennal club slightly shorter and the punctures on pygidium are less distinct. REMARKS The species is very similar in external morphology to E. metallica, and may externally only be distinguished by the unfused antennomeres 3-5. The elongate shape of aedeagus and the weakly curved parameres provide best features for separating the taxon from all other so far known Emphania species.Published as part of Ahrens, Dirk & Fabrizi, Silvia, 2008, A taxonomic revision of the Malagasy genus Emphania Erichson, 1847 (Insecta, Coleoptera, Scarabaeidae, Sericini), pp. 917-927 in Zoosystema 30 (4) on page 926, DOI: 10.5281/zenodo.452585

La disfunzione erettile. In Simonelli C., Fabrizi A., Rossi R., Tripodi F (a cura di) Sessuologia clinica. Diagnosi, trattamento e linee guida internazionali,
Gli script sociali nella cultura occidentale definiscono la sessualità maschile come “attiva, caratterizzata da un costante ed elevato desiderio sessuale, e orientata alla prestazione”, attribuendo così un ruolo centrale all’erezione [1,2]. La mascolinità è definita attraverso attributi come la forza fisica, l’eterosessualità, il potere sulle donne e sugli altri uomini, il non comunicare alcune emozioni (come rimorso e in-certezza, che possono far pensare alla vulnerabilità), l’indipendenza economica e l’abilità nella conquista sessuale. In un tale quadro culturale, la difficoltà a ottenere o mantenere l’erezione può rappresentare una forte fonte di disagio per l’uomo e lo stesso timore riguardo le fu-ture performance può divenire un fattore di rischio per la disfunzione erettile e il benessere sessuale in generale.
La salute sessuale è un concetto articolato, influenzato da fattori biologici, psicologici e relazionali [3-5] in cui le dimensioni socioculturali modulano l’espressione sessuale in entrambi i generi [6]. Anche le esperienze passate, sia nella famiglia d’origine sia con il gruppo dei pari e più in generale nelle istituzioni e nel contesto sociale allargato (religione, scuola, insegnanti, mass-media), esercitano un’influenza importante nello sviluppo individuale e incidono profondamente sulla modalità in cui ci si rappresenta e si vive l’affetto e l’amore. Sempre più chiaramente si osserva come i fattori psicologici e interpersonali hanno un ruolo importante nell’eziologia e nel mantenimento dei problemi sessuali
