Skowron Volponi MA 2019”; “Genitalia slide ♂, No. MSV-18” Will be deposited in the Natural History Museum in London. Description. Alar expanse 29 mm, body length 15 mm Head: antennae black with blue sheen, beige scales form a thin longitudinal stripe on exterior edge gradually widening towards tip, beige scales on margin of each antennae segment ventrally, larger, black and white scales at antennae base; frons smooth-scaled, black with metallic blue sheen; vertex covered with elongated black scales with metallic blue sheen, small patch of smooth white scales adjacent to complex eyes; labial palpi long and upturned, silvery black and bright white: elongated white scales at base, white scales mixed with black in proximal half ventrally and dorsally, in distal half white scales interiorly, ventral distal half black, tip black with several creamy white scales; pericephalic hairs black and white; complex eyes matt dark brown; proboscis long and functional, orange brown. Thorax: patagia black with metallic blue/green sheen, entire thorax covered with black scales with strong metallic blue sheen, minute white hairs on mesothorax; tuft of white mixed with some black hairs laterally below wing insertion protruding onto abdomen. Legs: fore coxa black with blue sheen, several white scales near base; fore femur, tibia and tarsi black with blue sheen, smooth-scaled dorsally and with elongated scales forming two tufts on ventral side of femur and tibia; midlegs black with blue sheen, some smooth white scales ventrally on tibia, elongated black with blue sheen mixed with white scales at distal end of tibia dorsally, spurs black and white; hind legs long, black with blue sheen, smooth white scales interiorly on proximal half of tibia, ventrally smooth, two very peculiar tufts of elongated scales, bluish black with some white, which form an imitation of two erected spines on the exterior side of the hind tibia, whereas interiorly on distal half of tibia and 1 st tarsomere the scales are uniformly elongated, smooth-scales ventrally and dorsally between exterior and interior tuft on tibia, as well as between the two tibial “spines”, tarsomeres 2–5 and distal end of 1 st tarsomere smooth-scaled. Forewing: almost entirely opaque with two very narrow longitudinal transparent areas from base; black with intense dark blue/purple or greenish sheen depending on the angle of light rays, lighter blue scales along cubital and subcostal veins from base. Hindwing: almost entirely transparent but wing membrane tawny; veins, discal spot and cells between veins CuA 2 and CuA 1 covered with black scales with blue sheen (leaving only a small transparent spot in these cells); smooth white scales on inner margin in basal half; cilia black. Abdomen: dorsally black with dark blue/greenish sheen; sternites black with blue sheen and thin white bands on each posterior margin. Male genitalia (Fig. 3): Valvae long and upturned, narrowed distally, densely covered with long setae. Tegumen narrow and slightly arched, uncus with a ring of long setae at tip. Saccus short, blunt-ended. Aedaegus simple, 1 length of valva. Female unknown. Variability. The individual filmed in 2017 was significantly smaller than the holotype. Differential diagnosis. From M. auricollis, M. paolo sp. nov. differs primarily in the lack of a large purple patch on the hindwing and the colouration of antennae, labial palpi and head (rufous orange in the species compared), the valva of male genitalia are slightly narrower and more elongated in M. paolo sp. nov.; from the Moluccan M. dohertyi in the overall body colouration (black-brown in species compared), especially of labial palpi and antennae (lack of rufous scales in M. paolo sp. nov.). From the New Guinean species, M. paolo sp. nov. differs in the following: from M. atra in the lack of red scales on labial palpi and antennae, colouration of thorax and abdomen ventrally, as well as of forecoxa, forewing and cilia (brown-black in M. atra); from M. funebris, in the lack of rufous scales on labial palpi, forelegs and tegulae, white or grey scales on mid and hind tarsi, as well as the hyaline-yellow colouration of the hindwing (hyaline-white in M. funebris). Moreover, M. paolo sp. nov. has hind leg tufts in the form of two erected “spines” (Fig. 1, Suppl. video), a feature which seems to be unique for this species, however only pinned specimens of all the remaining Melanosphecia species are known and it is difficult to determine the exact conformation of their hind leg tufts as it appears on live individuals. Interestingly, the male genitalia are very similar to those of Heterosphecia bantanakai, although the two sesiids are completely different in external morphology and their COI sequences differ by 10%. Habitat and conditions of occurrence. Pebbly river bank surrounded on one side by mixed plantations and the other by a semi-evergreen rainforest. In 2017 seen on a hot, sunny day at 1:30 pm, air temperature was 32°C. In 2019 seen once on a hot sunny day (34°C) around 12:00 and the second time on a hot cloudy day with only a bit of sunshine at 3:30 pm (35°C). Behaviour. M. paolo sp. nov. was found mud-puddling (Suppl. video: time code 00:23–02:12), a behaviour of sucking up liquids from moist substrate recently observed for a number of Oriental Sesiidae (Gorbunov, 2015; Quicke et al., 2018; Skowron et al., 2015; Skowron Volponi & Volponi, 2017, 2018), on a river bank. It landed on moist rocks, sometimes surrounded by algae (Fig. 1). When puddling, it would fly from one rock to another in a rugged flight (Suppl. video TC 02:41–03:00), in a similar manner to Pompilidae wasps approaching their burrows. It was observed ejecting excess water during puddling, which indicates it is puddling for salt or other minerals and not just for the moisture. In flight, the sesiid arches its abdomen which gives it an even more pompilid wasp-like appearance (Suppl. video: TC 03:01–03:43). This clearwing moth actively uses the long hind legs for locomotion or to cling on to a rock during puddling (Suppl. video: TC 01:51–02:12), in contrast to, for example, Heterosphecia pahangensis Skowron, 2015 (a species also belonging to the Osminiini tribe), whose hind legs are dysfunctional in terms of locomotion. It rests with its wings folded back against its body. DNA barcode analysis. A 648 bp fragment of the mitochondrial cytochrome c oxidase subunit I gene (COI) was sequenced (GenBank accession number MN514946) and it confirmed placement of M. paolo sp. nov. within the Osminiini tribe, however no other species of the Melanosphecia genus have been barcoded to date, thus comparisons were not feasible. From published records, the M. paolo sp. nov. COI sequence revealed highest identity with Heterosphecia pahangensis Skowron (8.4% divergence), H. bantanakai Arita & Gorbunov (10% divergence), Pyrophleps ellawi Skowron Volponi, 2017 (10.3% divergence) and P. vitripennis Arita & Gorbunov (11.1% divergence). Etymology. I dedicate this species to my husband, Paolo Volponi, a brilliant filmmaker and clearwing moth enthusiast, whose help and assistance in the field have been crucial in the studies of this and many other Sesiidae species.Published as part of Skowron Volponi, Marta A., 2019, A new species of spectacular spider wasp mimic from Thailand is the first representative of the genus Melanosphecia Le Cerf 1916 (Lepidoptera: Sesiidae: Osminiini) to be filmed in the wild, pp. 295-300 in Zootaxa 4695 (3) on pages 296-299, DOI: 10.11646/zootaxa.4695.3.4, http://zenodo.org/record/353263
L’irriducibilità dell’umano in «Corporale» di Paolo Volponi
No full textCon Corporale (1974), romanzo dalla gestazione quasi decennale, Paolo Volponi conclude la propria trilogia sulla società industriale avviata con Memoriale (1962) e La macchina mondiale (1965). Nell’immaginario degli anni Sessanta la fabbrica è manifestazione di un progresso scientifico-tecnologico volto a svilire l’elemento umano e a ridurre l’uomo a un mero ingranaggio. Il ritorno a una dimensione corporea dell’esistenza – esibito sin dal titolo – rappresenta quindi per Volponi una forma di resistenza all’alienazione indotta dalla modernità industriale. L’ossessione per gli aspetti anche deteriori della fisicità pone in risalto l’irriducibilità di ciò che è propriamente umano: la carne è inalienabile, a differenza della coscienza, ed è in definitiva l’unica cosa che contraddistingue l’individuo dai macchinari delle fabbriche in cui lavora
Le mosche del capitale di Paolo Volponi : lavoro, identità, assoggettamento
No full textCon Le mosche del capitale Paolo Volponi narra l’ingresso dell’industria in un ordine politico-economico dominato dal potere del capitale finanziario e dalle logiche neoliberiste. Il nuovo paradigma che s’impone è la «negazione dell’industria e della sua cultura» : è il dominio del neocapitalismo. Il legame tra lavoro e identità sociale dell’individuo ha assunto carattere biopolitico perché l’esistenza umana è diventata oggetto privilegiato di strategie politiche neocapitaliste. Il lavoro come apparato che produce identità sociale entra in crisi e Volponi rappresenta questa trasformazione nei termini di un’omologazione identitaria di portata cosmica. Nel disegno allegorico delle Mosche, il potere disciplina ogni forma di individualità assoggettandola, integrandola e governandola. Esso si esercita soprattutto in quanto linguaggio: un linguaggio feroce e nello stesso tempo ridicolo.In Le Mosche del capitale Paolo Volponi describes the shift of the industrial paradigm into a model dominated by financial capitalism and neoliberism. The new paradigm is characterized by the “negation of industry and its culture”: it is the reign of neocapitalism. The link between work and social identity of individuals is biopolitical: human existence has become the privileged object of neocapitalist policies. Labour as an apparatus for the production of social identity declines and Volponi represents its crisis as a global - even cosmic - identitarian normalization. In the allegory of the Mosche, power disciplines every form of individuality: it subjectifies single identities through a homologation. Power is expressed above all through language: a sharp and at the same time ridiculous language

Weighing antimatter: AEg over bar IS Phase 2, upgrades and first data
No full textAEg over bar IS (Antimatter Experiment: Gravity, Interferometry, Spec-troscopy) is an experiment at the Antiproton Decelerator (AD) facility at CERN whose goal is to study the asymmetry between matter and antimatter and, in particular, the effect of the Earth's gravitational field on antihydrogen (H over bar ). During the 2018 run, H over bar was formed, leading into considerable gain of knowledge on the processes involved. Therefore, in the last two years, during CERN LS2, multiple upgrades to the experiment have been carried out, spanning from new degraders, a new H over bar formation trap scheme, an entirely new control system, a more efficient positronium (Ps) converter, and more efficient sensors. All this work is necessary towards the goal of creating the first pulsed beam of neutral H over bar , which will enable inertial studies on antihydrogen with high degrees of precision. This contribution presents different upgrades, their validation with the antiprotons beam, and the further developments foreseen in the future
Comparison of three different media for the detection of E. coli and coliforms in water.
No full textThe European Drinking Water Directive defines reference methods for the enumeration of microbiological parameters in drinking water. The method to be used for Escherichia coli and coliforms is the membrane filtration technique on Lactose TTC agar with Tergitol 7. Many technical drawbacks of the procedure, as well as its limitations regarding the recent taxonomy of coliforms, make it necessary to evaluate alternative methods. Two alternative assays, a chromogenic media (m-ColiBlu24®) and a defined substrate technology-DST test (Colilert 18/Quanty TrayTM) were compared with the ISO standard with attention to the phenotypic characteristic of the isolates. Results showed that the ISO method failed to detect an important percentage of coliforms and E. coli while m-ColiBlu24® and Colilert 18 provided results in a shorter time allowing the simultaneous detection of E. coli and coliforms with no further confirmation steps
Paolo Volponi
No full textDer Artikel ist ein literaturwissenschaftlicher Beitrag über einen der herausragenden Schriftsteller Italiens des 20. Jahrhunderts. In dem Beitrag werden nicht nur die wichtigsten beruflichen Etappen des Autors Paolo Volponi nachgezeichnet, sondern und insbesondere das Werk dieses außergewöhnlichen Literaten vorgestellt und interpretiert. Trotz seiner unbestrittenen Bedeutung für die italienische Literatur der Nachkriegszeit blieb Volponis Resonanz im Ausland – abgesehen von den Erfolgen von „Ich, der Unterzeichnete“, „Die Weltmaschine“ und in kleinerem Maße von „Der Speerwerfer“ und „Ich seh dich unter den Arkaden“ – bisher eher gering. Noch immer warten seine eigenständige und kraftvolle Lyrik und seine komplexen Romane wie „Corporale“ und „Le mosche del capitale“ auf eine Übersetzung ins Deutsche. Ein wirklicher Mangel, denn Volponis Texte bleiben unverändert lesenswert. Sie sind nicht nur zeitgeschichtliche Dokumente, die uns helfen, das heutige Italien und die europäische Industriekultur zu verstehen, die soziale Probleme behandeln, welche uns alle betreffen wie die in „Le mosche del capitale“ beschriebenen Massenentlassungen. Volponis Werke behandeln zugleich ein individuell-menschliches Thema: die Einsamkeit der ‚diversi’, der Außenseiter, und ihre tragische Sehnsucht nach Gerechtigkeit und Veränderung in einer entfremdeten Welt
