Cnephasia kenneli Obraztsov. A 1956
No full text14. Cnephasia kenneli Obraztsov, 1956 Material examined. Zanjân Prov.: 12 ♂♂, 1 ♀, Sohrein Vlg. to Dagâhi Vlg. Rd., 6 km to Dagâhi Vlg., N 36˚53΄03.8̎ E 048˚28΄08.3̎, 4084 m, 4.vi.2012, Âlipanâh, Falsafi leg. (GS: HA-2404, HA-2081, HA-2086, HA-2388, HA-2394, HA-2396, HA-2397). Diagnosis. Among identified females of the longana species-group, C. kenneli is most similar to C. amseli (D. Lucas, 1942) in the female genitalia (see Razowski 1965: 270, 274; Razowski 2002: 91). In both species the lateral parts of the sterigma are triangular and narrowed distally, with the posterior margins concave medially. In both species the ostium bursae is rounded and antrum is nearly cup-shaped and slightly sclerotized. The relative length of the ductus bursae to the corpus bursae and the size and shape of signum in both species are the same. However, in C. amseli there is a relatively long inner sclerotization at the posterior half of the ductus bursae, whereas in C. kenneli there is a twisted sclerotized structure inside the ductus bursae which is located at its anterior half (Figs. 8A, C). Moreover, in C. kenneli the papillae anales are wider than in C. amseli. The male genitalia of C. amseli are still unknown; on the other hand, the forewing pattern of the latter species is different from that of the C. kenneli. As stated by Razowski (1965), C. kenneli is superficially similar to C. dispersana; however, the two can be distinguished by their genitalia. Description of the female. Head (Fig. 6G): Scales mostly smooth, elongate, white; white to creamy-light brown on frons; labial palpus sinuate with third segment pointed anterad, creamy-white irregularly admixed with light brown to yellowish-brown scales dorso-laterally, except creamy-white first segment, with length 1.83 times the horizontal diameter of compound eye, second segment longest with slightly elongate and erect scales dorso-apically; antennae nearly white dorsally at one-third, the remaining ringed with white and creamy-light brown scales, sensilla shorter than the male. Thorax: Creamy-white admixed with light brown scales, with a pair group of erect creamy-white scales admixed with dark brown scales posteriorly. Female slightly larger than male, with forewing length 11.4 mm (n = 1). Forewing shape and pattern similar in males and females (Figs. 6A – D), slightly broadened distally, with nearly straight costa finely arched outwards basally, rounded apex, obliquely rounded termen; upperside grayish-cream, with a few scattered brown to pale brown scales at dorsum margin and distal end, cilia creamy-white with a gray brown dividing transverse line; underside light brown except narrow creamy costal margin. Hindwing (Figs. 6A, B) upperside darker than the forewing, grayish-light brown, cilia creamy-white with a gray brown dividing transverse line; underside paler than the forewing, cream. Abdomen: Grayish-cream, with elongate yellowish-cream scales dorsally. Female genitalia (Figs. 8 A–C) with papillae anales moderate, medially broad, apically rounded; ostium bursae circular, heavily sclerotized ventrolaterally; apophyses posteriores longer than apophyses anteriores, 1.3 times length of apophyses anteriores, both gradually narrowed distally; lateral parts of sterigma broad, gradually tapering laterally, slightly concave medially on posterior margin, with several long setae mostly at median part; antrum cup-shaped, weakly sclerotized (Figs. 8A, B); ductus bursae narrow, with a twisted, irregular sclerotized structure at anterior half (Figs. 8A, C); ductus seminalis arising from anterior end of ductus bursae, slightly behind connection with corpus bursae (Figs. 8A, C); corpus bursae large, pear-shaped, signum moderate. Distribution. Jordan (Jordan Valley), Asia Minor (Eibés, Malatya), Syria?, Kulscha? (Kennel 1901, 1910, Obraztsov 1956, Razowski 1965). Remarks. Cnephasia obsoletana was described by Kennel (1901) based on a single male specimen from the Jordan Valley, Jordan. Obraztsov (1956) recognized that the name was preoccupied and proposed the replacement name Cnephasia kenneli. In 1910 Kennel described Tortrix obsoletana from a male specimen from Eibés, Malatya in southeastern and eastern Asia Minor. According to Razowski (1965), the latter is considered a synonym of C. kenneli. The female has remained undescribed. During the present study, a female collected at the same locality as C. kenneli males was discovered in the HMIM, both sexes collected by the author in Zanjan Province. Because the female is superficially similar to the males of C. kenneli, the two sexes are considered conspecific. As revealed in this study, there is considerable intra-specific variation in the male genitalia of C. kenneli, especially in the shape of the valva. As figured by Razowski (1965: 264, 265), the valva of C. kenneli is pointed, while in examined males the apical part of the valva is more rounded (Figs. 7A, E, H, I) or obliquely rounded (Fig. 7J). In some specimens, the valva is curved internally behind the mid-ventral part (Fig. 7H). Also, the width of the valva in examined males is slightly less than that figured by Razowski (1965). Some of this variation may be an artefact of slide mounting. During the preparation of male genitalia, the lower margin of the apical part of the valva usually turns back and thereby the apical part seems narrower than it actually is. Additionally, the free termination of the sacculus is normally turned more or less upward on the disc of the valva (Figs. 7A, D, I, J), but sometimes it may turn downward depending on slide preparation (Figs. 7E, F, H). Cnephasia kenneli has rather moderate, simple socii (see Razowski 1965: 264, 265), however, in the examined males the socii are relatively wide, 1.6 times the width of the uncus at its narrowest point (n = 5). Furthermore, in most of the examined males, the free termination of the socii are nearly straight or very slightly depressed medially, but they often appear bilobed, i.e., a slightly longer apically rounded lateral lobe and a somewhat shorter medial one (Figs. 7A, C, E). The terminal plate of the gnathos in the examined males is wedge-like (Figs. 7A, C, E), whereas it appears to be trapezoidal in figures presented by Razowski (1965: 264). The density of spines at the free termination of the sacculus also varies among the specimens (Figs. 7A, D, E, F, H–J). Comments. Although males and females are similar superficially, a few differences (except the shorter length of sensilla of female antennae) were observed between them. The female is somewhat larger than male; i.e., forewing length 9.7 – 11.7 mm (= 10.73 mm ± 0.52, n = 12) in males, 11.4 mm (n = 1) in the female. Moreover, the female has a slightly smaller compound eye (Fig. 6G) compared to that of males (Figs. 6E, F). Also, the dorsal surface of the male antennae is covered with white scales only basally or ringed throughout, whereas in female the white scales extended to the proximal one-third of the antennae. In both male and female, the number of scales in darker rings of the antennae is less than those of the white rings.Published as part of Alipanah, Helen, 2019, An overview of the tribe Cnephasiini (Lepidoptera: Tortricidae: Tortricinae) of Iran with description of a new species, pp. 501-521 in Zootaxa 4661 (3) on pages 508-514, DOI: 10.11646/zootaxa.4661.3.5, http://zenodo.org/record/338136

Prompt charm production in pp collisions at √<span style="text-decoration:overline">s</span>=7 TeV
Get PDFCharm production at the LHC in pp collisions at s√=7 TeV is studied with the LHCb detector. The decays D0→K−π+, D+→K−π+π+, D⁎+→D0(K−π+)π+, D+s→ϕ(K−K+)π+, Λ+c→pK−π+, and their charge conjugates are analysed in a data set corresponding to an integrated luminosity of 15 nb−1. Differential cross-sections dσ/dpT are measured for prompt production of the five charmed hadron species in bins of transverse momentum and rapidity in the region 0<pT<8 GeV/c and 2.0<y<4.5. Theoretical predictions are compared to the measured differential cross-sections. The integrated cross-sections of the charm hadrons are computed in the above pT-y range, and their ratios are reported. A combination of the five integrated cross-section measurements gives

On the history of national medicine: Vasily Parmenovich Obraztsov (1851–1920)
No full textВ статье рассматриваются основные моменты биографии классика отечественной медицины – киевского терапевта В. П. Образцова. На основе многочисленных архивных документов и критического анализа литературных источников предпринята попытка создать его научную биографию с устранением ошибок и неточностей, легенд и домыслов. В. П. Образцов представлен как один из трех ведущих клиницистов страны (наряду с В. Н. Сиротининым и В.Д. Шервинским). Уточнен характер основных научных приоритетов В. П. Образцова (разработка метода глубокой скользящей пальпации органов брюшной полости; описание клинической картины и диагностических критериев острого тромбоза венечных артерий сердца, которое положило начало современному учению об инфаркте миокарда). Рассмотрена одна из важнейших научных заслуг этого выдающегося врача, педагога, ученого – создание оригинальной научной клинической школы, крупнейшей (наряду со школой М. В. Яновского в Петербурге) в России XX века. Показана его роль в подготовке и проведении первых съездов российских терапевтов. Впервые правдиво показано своеобразие яркой, сложной и необычайно привлекательной личности Василия Парменовича, его нестандартный жизненный путь с трагичным финалом. Авторы показывают, что В. П. Образцов был самой крупной фигурой в истории отечественной терапевтической клиники после С. П. Боткина.In this article, the authors discuss the main points of life of V. P. Obraztsov – a general practitioner from Kiev, one of the fathers of national medicine. While eliminating errors, inaccuracies, fables, and speculations, the authors attempt to create his scientific biography on the basis of numerous archival documents and a critical overview of the sources of literature. V. P. Obraztsov is viewed as one of Russia’s three leading clinicians (alongside with V. N. Sirotinin and V. D. Shervinsky). Another aim of the article is to specify the nature of the main scientific priorities (the deep sliding palpation of abdominal cavity organs method
development; the description of clinical aspects and diagnostic criteria of acute coronary thrombosis that laid the foundation for the modern understanding of myocardial infarction). Beyond that, one of the major academic achievements, i.e. the creation of a unique clinical school, the most influential in Russia (together with M. V. Yanovskiy’s school in Saint Petersburg) is examined. V. P. Obraztsov’s role in organizing the first congresses of general practice in Russia is presented. The article shows the striking, complex and exceptionally attractive individuality of Vasily Parmenovich, his unconventional life journey that
ended tragically. The authors demonstrate that V. P. Obraztsov was the most important figure in the history of national internal medicine after S. P. Botkin
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
Get PDFFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
