Ruzante sulle scene del '900
No full textRuzante sulle scene del ‘900 nasce da un progetto di catalogazione di tutti i materiali, per la gran parte inediti, relativi agli spettacoli che nell’arco di oltre un secolo hanno fatto rivivere sulla scena la figura e l’opera di Angelo Beolco. Ad un sintetico inquadramento introduttivo segue un catalogo costituito da centosessanta schede che illustrano altrettante messinscene, datate dal 1902 al 2005: un percorso che muove dalle esperienze dei grandi protagonisti della regia europea d’inizio Novecento (come Copeau e Dullin) e si spinge fino alle messinscene più recenti, che oltre ad aprire nuove modalità interpretative spesso si confrontano con la memoria tramandata dagli artisti del passato.
Dalla minuziosa raccolta di dati emerge la figura di un Ruzante che, lungi dall’essere limitato alla comprensione entro un preciso ambito geografico, offre sempre nuovi impulsi alla creazione artistica, incarnandosi in poetiche e contesti sempre originali, come si addice ai più fortunati testi dei classici. La maggior parte delle schede, che offrono informazioni dettagliate sui diversi allestimenti, è corredata da una selezione di giudizi critici e da materiale iconografico (foto di scena, bozzetti, riproduzione delle locandine): l’articolato percorso conduce il lettore sul filo della memoria ruzantiana attraverso diversi ambiti culturali, lungo tutto il Novecento, ma anche incontro a differenti modalità registiche e a molteplici approcci a Ruzante.

No full textNeoempheria ferruginea (Brunetti, 1912) (Fig. 1 a–f) Mycomya ferruginea Brunetti, 1912: 74; Senior-White 1922: 84. [Japanese name: nagamado-kinoko-bae] Description. Head (Fig. 1 a): yellow in ground color, with dark brown mark on occiput and dark brown stripes along occipital and frontal furrows. Frons bare. Lateral ocelli on black well-developed ocellar prominence. Ocellar setae absent. Face yellow. Mouthparts short. Clypeus yellow, triangular, with scattered setae at apical margin. Palpus dark brown. Antenna 4.5 times as long as head, shorter than head and thorax together. Scape and pedicel yellow. Pedicel with single seta slightly shorter than 1 st flagellomere. Flagellum dark brown. Thorax (Fig. 1 b): yellow in ground color. Scutum with 5 dark brown stripes (1 medial, 2 sublateral and 2 lateral). Setae present on each stripe. Scutellum with 2 pairs of lateral setae. Wing (Fig. 1 c): hyaline, tinged with dark brown on apical 1 / 4 and posterior margin, distinct dark brown mark on each of veins Rs and R 4. Vein sc-r ending in basal 1 / 4 of anterior margin of cell r 1. Cell r 1 4 times as long as wide. Halter yellow, tinged with dark yellow in knob. Legs (Fig. 1 d): yellow. Tibia with erect setae slightly shorter than diameter of tibia. Abdomen (Fig. 1 b): yellow in ground color, with dark brown stripes on each abdominal tergite. Male genitalia (Fig. 1 e): yellow in ground color. T 9 with dorsal projection flattened dorsoventrally, bearing numerous setae on ventral side, tapered to apex. FIGURE 1.

Note that the original photo of the wing was horizontally flipped. Abbreviations: dp, dorsal projection of of tergite 9; R 4 and R5, 4th and 5 th radial veins; r 1 and r4, 1st and 4 th radial cells; cu p, posterior branch of cubital vein; a1, 1st branch of anal vein. Photographs examined. Lectotype, here designated. INDIA: 1 ♂, “Kurseong/ 5000 Feet [= 1500m]/ E. Himalayas/ 3 -VII-08 ”, “Myco/ ferruginea / Brun. Type ♂”, “Myco/ ferruginea / ♂”, “ TYPE ”, “ 1904 / 20 ” (ZSI) (Fig. 1 f). Distribution. India (Darjeeling, Kolkata, Shillong) (Brunetti 1912; Senior-White 1922), Sri Lanka (Peradeniya) (Senior-White 1922). Remarks. Brunetti (1912) described this species based on two males and one female, without explicitly designating a holotype, though the specimen from Kurseong was labeled as type when examined later (Edwards 1924). ZSI holds only a single male from Kurseong with type labels (Fig. 1 f) (Dr. S. Sheela, pers. comm.) and it is designated here as the lectotype. As Edwards (1924) noted, the wing marks of the lectotype (Fig. 1 c) are different from figure 12 of Brunetti (1912) in the following points: the wing anterior to veins M and R 4 + 5 is hyaline and has distinct dark marks on veins Rs and R 4; the dark brown mark in cell r 4 is continuous to cell cua 1 via the apex of cell r 5, all of cell m 1, and the apical portion of cell m; the brown mark in cell m 1 fills the entire cell; and the brown mark on cell cu p expands into the apical half of the cell.Published as part of Sueyoshi, Masahiro, 2014, Taxonomy of fungus gnats allied to Neoempheria ferruginea (Brunetti, 1912) (Diptera: Mycetophilidae), with descriptions of 11 new species from Japan and adjacent areas, pp. 139-164 in Zootaxa 3790 (1) on pages 140-141, DOI: 10.11646/zootaxa.3790.1.6, http://zenodo.org/record/22671
Voltammetric determination of Vitamin B6 in food samples and dietary supplements
No full textA simple and rapid voltammetric method based on the use of disposable screen-printed electrodes is proposed for the determination of vitamin B6. The influence of the pH on the voltammetric response was analyzed. Estimation of the linear range (2.0•10-6/7.2•10-5 M), calibration function, limit of detection (1.5•10-6 M) and reproducibility was performed along with the determination of possible interferences from species present in real samples. The proposed analytical system was successfully applied for the determination of pyridoxine in multivitamin supplements, energy drinks and breakfast cereals by using the standard addition method
Mythenteles indica Brunetti
No full textMythenteles indica (Brunetti) (Fig. 14) Empidideicus indicus Brunetti, 1917: 77. Brunetti, 1920: 260. SeniorWhite, 1923: 1. Painter, 1932: 356. ? Cyrtosia indica (Brunetti). Bezzi, 1925: 188. Glabellula indica (Brunetti). Bezzi, 1926: 255. Bowden, 1975: 166. Evenhuis, 1983: 476. Mythenteles indica (Brunetti). Evenhuis, 2002 b: 36. As can be seen from the list of generic placements above, this species has had a confused taxonomic history. Brunetti (1917) originally described the species in Empidideicus. However, the illustration of the wing venation in the original description depicting a distinct small triangular marginal cell precludes it from being a member of that genus. Subsequent treatments of the species by Bezzi had it questionably in Cyrtosia (1925) and later (1926) in Glabellula. Bowden (1975), apparently unaware of Bezzi’s (1926) earlier placement of the species in Glabellula, also placed indica in that genus with the notation “N. comb.” Bezzi’s and Bowden’s placement in Glabellula were undoubtedly due to the presence of the small triangular marginal cell in the wing. The only known Old World genus in Bombyliidae at the time of Bezzi’s and Bowden’s placement that possessed such a cell was Glabellula. However, the remainder of the wing venation (see Fig. 14) does not match Glabellula. The original description is quoted here. Female. “Frons apparently about onefourth the width of the head, yellowish; antennae black; proboscis more than 1 1 / 2 times height of head. Thorax black, practically bare; humeri bright yellow; Abdomen black, hind margins of segments pale yellow, and a yellow transverse line across middle of 1 st and 2 nd segments. Legs black, knees and tips of tibiae yellowish. Wings pale grey; auxiliary vein short, ending free: 1 st vein ending at middle of costa; praefurca beginning at middle of 1 st vein; 2 nd vein very short, directed abruptly upwards, ending in 1 st vein near tip; 3 rd vein in line with praefurca, simple, ending a little before wing tip; 4 th vein forked at half its length after quitting basal cells, the portion dividing those cells hardly less distinct; 5 th forked, base of upper branch forming lower side of 2 nd basal cell; 6 th vein reaching wing border. First basal cell a little longer than 2 nd; bifurcation of praefurca opposite tip of 2 nd basal cell. Length 1 mm.” Male. Unknown. Types. Brunetti (1917) originally described this species based on “four paratype specimens in the Indian Museum in very indifferent condition taken by Dr. Annandale at Simla, 7,000 ft.” Only 2 of these 4 specimens could be found in NZSI. One of the 2 surviving specimens has the head missing. The specimen with the head intact is designated here as lectotype female to stabilize the nomenclature of the species. The indication of the type of Empidideicus indicus as a holotype in Evenhuis (2002 b: 36) was in error. Remarks. No specimens other than those from the original type series are known. Despite the lack of specimens for examination, the original description and accompanying illustration of the wing give enough evidence of salient characters to show that it belongs to Mythenteles. Along with M. hispanicola, M. infrequens, M. coptopheles, and M. wadimurri, this species lacks crossvein dmcu. Distribution. Known only from the type locality in Simla, India.Published as part of Evenhuis, Neal L., 2003, World revision of the microbombyliid genus Mythenteles Hall & Evenhuis (Diptera: Mythicomyiidae), pp. 1-28 in Zootaxa 346 on pages 17-18, DOI: 10.5281/zenodo.15713
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
