However, this taxonomic arrangement was modified by Bragg (2005), who synonymized <i>Xylobistus</i> with <i>Dinophasma</i>, based on the hypothesis of a strict relationship between <i>X. braggi</i> and <i>Dinophasma viridis</i> Bragg, 2005 from Borneo, which shows a certain similarity with the former species.</p> <p> Because of the presence of a strongly developed ventral undulating lamina on the femora, and reduced tarsal claws pectination, the new species is clearly related to <i>D. braggi</i> (Zompro, 2004) from Borneo. <i>D. maalon</i> <b>n. sp.</b> can be distinguished from the mentioned species by the following set of male morphological characters: more slender body and overall size smaller; head dorsum with a flat tubercle (in <i>braggi</i>: two); absence of tegminae (in <i>braggi</i> present); hind wings: base of costal region spine-like, acutely pointed (in <i>braggi</i> hump-like, not acutely pointed); weakly developed tubercles and lobes on abdominal tergites (in <i>braggi</i> strongly developed); straight cerci (in <i>braggi</i> curved). Additionally, a difference is found in the length ratios of the abdominal segments, and shorter hind wings.</p> <p> These two species differ significantly from all the other known members of the genus for the peculiar features of the legs, shortened antennal segment III and traits of the egg in <i>D. braggi</i>. More material, especially the female and egg of <i>D. maalon</i> <b>n. sp.</b>, is needed to clarify the current taxonomical status of the genus <i>Dinophasma</i>.</p> <p> <b>Acknowledgements.</b> I am grateful to George Beccaloni (BMNH), Phil Bragg (Nottinghamshire, England) and Oliver Zompro (Max-Planck-Institute, Plön, Germany) for providing useful information and photographic material.

    DOMPERIDONE E MORTE CARDIACA IMPROVVISA: IMPLICAZIONI MEDICOLEGALI

    No full text
    Introduzione: la morte cardiaca improvvisa (MCI) è definita come una morte naturale per cause cardiache, che si realizza al massimo entro un’ora dalla comparsa della sintomatologia acuta in un soggetto nel quale, indipendentemente dalla conoscenza di una cardiopatia preesistente, il decesso giunga inatteso e per il tempo e per la modalità. La MCI usualmente riconosce il concorso di concause pre-esistenti, a diversa espressione disfunzionale, sulle quali agisce un fattore scatenante, il quale può assumere rilievo forense.Materiali e metodi: è presentato il caso di una donna di 47 anni con storia di dipendenza da alcool e prolasso valvolare mitralico noto, che, senza prescrizione medica, ha assunto per disturbi gastrointestinali 2 compresse da 10 mg di Domperidone (D), alle ore 09.00 e alle ore 12.00 della stessa giornata nella quale, alle ore 17,45 andava incontro a morte improvvisa. Ciò avveniva nel corso di una seduta di psicoterapia. L’esame necroscopico era corredato da prelievi ed esami tossicologici con ricerca di D su sangue e screening “general unknown” su urine (LC-MS/MS).Risultati: l’esame cardiopatologico ha rilevato macroscopicamente lieve ipertrofia cardiaca e minimo prolasso del lembo anteriore della valvola mitrale, ed istologicamente ipertrofia miocitaria, diffusa disorganizzazione delle miofibre, edema e fibrosi perivascolare. A livello epatico steato-cirrosi avanzata. Gli esami tossicologici su sangue hanno accertato una concentrazione ematica di D pari a 36,81 ng/mL (86 nM); la ricerca di xenobiotici su urina ha dato esito negativo.Conclusioni: si tratta di un caso di MCI di tipo aritmico, correlabile sotto il profilo concausale a fattori preesistenti quali il prolasso mitralico1 ed una cardiomiopatia ad eziologia non nota (verosimilmente esotossica), implicanti la sussistenza di un quadro di instabilità elettrica miocardica con conseguente abbassamento della soglia di fibrillazione ventricolare. Il possibile effetto pro-aritmico è stato esercitato, a nostro avviso, dal Domperidone (D), farmaco a rischio di torsione di punta2 e di MCI, agente con un blocco dei canali del potassio della cellula cardiaca (IKr.) e correlata alterazione della fase di ripolarizzazione miocitaria da cui rischio di sviluppo di aritmie3. Le prime segnalazioni di tali effetti avversi risalgono a circa 10 anni or sono, comportando la diffida all’impiego del farmaco da parte della Comunità Scientifica. Studi recenti hanno stabilito, tra l’altro, per il D un basso indice terapeutico, potendosi documentare alterazioni della ripolarizzazione miocitaria già a partire da 30-60 nM (12,8-25.5 ng/mL)4. Inoltre, sebbene i predetti effetti avversi del D siano stati di recente recepiti dall’Agenzia Italiana del Farmaco (AIFA) con la sua nota del 14.11.20115, il D, per dosaggi bassi (5 mg), rimane di libera vendita per automedicazione, nonostante possa essere riconosciuto quale fattore trigger anche letale. Il D è metabolizzato a livello epatico, la sua somministrazione in soggetti epatopatici è pertanto controindicata, implicando il realizzarsi di picchi ematici elevati ed il prolungarsi del tempo di dimezzamento. Nel caso sopra esposto infatti, nonostante l’assunzione di un dosaggio entro il range terapeutico, il farmaco è stato in grado di determinare, in un soggetto epatopatico, l’instaurarsi di concentrazioni ematiche idonee a causare alterazioni della ripolarizzazione miocitaria ad evoluzione letale

    Nutrients recovery from anaerobic digestate of agro-waste: Techno-economic assessment of full scale applications

    No full text
    The sustainable production of fertilizers, especially those based on phosphorus, will be one of the challenges of this century. Organic wastes produced by the agriculture, urban and industrial sectors are rich in nutrients which can be conveniently recovered and used as fertilizers. In this study five full scale systems for the recovery of nutrients from anaerobic digestate produced in farm-scale plants were studied. Monitored technologies were: drying with acidic recovery, stripping with acidic recovery and membrane separation. Results showed good performances in terms of nutrients recovery with average yields always over 50% for both nitrogen and phosphorus. The techno-economic assessment showed how the specificity of the monitored systems played a major role: in particular, membranes were able to produce a stream of virtually pure water (up to 50% of the treated digestate) reducing the digestate volume, while drying, because of the limitation on recoverable heat, could treat only a limited portion (lower than 50%) of produced digestate while stripping suffered some problems because of the presence of suspended solids in the liquid fraction treated. Specific capital and operational costs for the three systems were comparable ranging between 5.40 and 6.97 € per m3 of digestate treated and followed the order stripping > drying > membranes. Costs determined in this study were similar to those observed in other European experiences reported in literature

    Gestione dei Rischi, Governance e Controllo

    No full text
    Il lavoro insiste sulla stretta connessione esistente fra struttura di corporate governance, meccanismi di controllo e gestione dei rischi. Fra le regole di un sistema di governance hanno assunto sempre più rilievo quelle di autodisciplina rappresentate dai codici di condotta, dei quali si analizzano gli aspetti relativi alla gestione dei rischi e il loro rapporto con le raccomandazioni espresse da organismi nazionali e sovra-nazionali. Un efficace ed efficiente sistema di governance dei rischi implica necessariamente un sistema efficace di controlli di matrice sia interna che esterna alle imprese: implementazione e supervisione da parte del board delle funzione di auditing e controllo, flussi informativi da e verso agenzie/enti regolamentari e mercati . I due sistemi sono strettamente connessi e complementari, dalla loro architettura e dal loro buon funzionamento dipende la possibilità di gestire correttamente le esposizioni ai rischi finanziari e di altro tipo
