So the Horizon Line Vanishes': Landscape and Abstraction in England from the 1930s to the 1950s

2010

This paper explores the tension between abstraction and figuration in English landscape painting from the 1930s to the 1950s, a transitional period marked by opposition between these two semiotic systems. The tension between tradition and new departure runs through the paintings and texts by John Piper and Peter Lanyon.

Durability of Dolutegravir-Based Regimens: A 5-Year Prospective Observational Study

2021

This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-1…

Transcontinental 2200 km migration of a Nathusius’ pipistrelle (Pipistrellus nathusii) across Europe

2021

A male Pipistrellus nathusii ringed in Pape Natural Park (S Latvia) in August 2015 was recovered recently dead in Pitillas’ Lagoon Natural Reserve (N Spain) in March 2017. At 2224 km in SSW direction, this is the first documented bat migration between these countries and worldwide the longest migration record of a bat. We also report other observations of this species in autumn in Northern Spain, suggesting that the Iberian Peninsula may be an important wintering area for Nathusius’ pipistrelles. Conservation measures should be agreed on by countries along the migration routes to improve the protection of this species. nonPeerReviewed

Synthesis of the New Ring System Bispyrido[4',3':4,5]pyrrolo [1,2-a:1',2'-d]pyrazine and Its Deaza Analogue

2014

Derivatives of the new ring systems bispyrido[4',3':4,5]pyrrolo[1,2-a:1',2'-d] pyrazine-6,13-dione and its deaza analogue pyrido[4'',3'':4',5']pyrrolo-[1',2':4,5]pyrazino [1,2-a]indole-6,13-dione were conveniently synthesized through a four-step sequence. Symmetrical derivatives of the former ring system were obtained through self condensation. On the other hand, condensation of 6-azaindole carboxylic acid with indole 2-carboxylic acid afforded the deaza analogue ring system. Derivatives of the title ring system were tested by the National Cancer Institute (Bethesda, MD, USA) and four of them exhibited modest activity against MCF7 (a breast cancer cell line) and/or UO-31 (a renal cancer cel…

Identification of phytopathogenic bacteria in maize seeds in Ukraine

2018

The main bacterial diseases of maize: bacterial wilt of maize (Pantoea stewartii subsp. stewartii), goss’s bacterial wilt (Clavibacter michiganensis subsp. nebraskensis), seed rot-seedling blight of maize (Bacillus subtilis), bacterial spot of maize (Pseudomonas syringae pv. syringae), bacterial leaf spot of maize (Pantoea agglomerans) and bacterial stalk rot of maize caused by several causative agents, were described. The causative agents of these diseases are often stored and transmitted with seeds, so seed analysis for the presence of phytopathogenic bacteria is an important step in the pathogen control system. For analysis, the corn seeds that were grown in the Poltava and Kiev regions …

A peculiar new Orthotrichum species (Orthotrichaceae, Bryopsida) from central Argentina

2007

A new epiphytic Orthotrichum species (Orthotrichum spiculatum F. Lara, Garilleti & Mazimpaka sp. nov.) is described from the sierra of Cordoba (Argentina). The new species has most of the characteristics of subgenus Pulchella (Schimp.) Vitt, but it is unique because of having eight exostome teeth pairs and 16 broad, strongly papillose endostome segments. Additionally, its upper leaves have green, acuminate, dentate–spiculate apices. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society, 2007, 155, 477–482.

Antimykotische Wirkstoffe, Mitt. Chlor-(1-piperazinyl)-1,3,5-triazine

1988

Aus der Umsetzung von Cyanurchlorid (1) mit den Piperazinderivaten 2a–c bei –20 bis 10° gehen die Dichlor-(1-piperazinyl)-1,3,5-triazine 3a–c hervor. Bei der erhohten Reaktionstemperatur von 40° erfolgt aus 1 und den Piperazinderivaten 4a–b Bildung der 2-Chlor-4,6-bis(piperazinyl)-1,3,5-triazine 5a–b. Zu gemischt substituierten Chlor-1,3,5-triazinen 9 fuhrt die nacheinander erfolgende Umsetzung von 1 mit 2 verschiedenen cyclischen sekundaren Aminen (6 und 8). Die Strukturtypen 3, 5 und 9 zeigen in den 1H-NMR-Spektren zwei fur Piperazinringe charakteristische Signalgruppen im Bereich 2.4–4.0 ppm. Unter den neu entwickelten Verbindungen finden sich Vertreter mit sehr starker antimykotischer W…

Die Zuordnung der Koppelungsgruppen zu den Chromosomen bei der Stechm�cke Culex pipiens L.

1972

Die Numerierung der drei Koppelungsgruppen von Culex pipiens L. (Laven, 1967b) stimmt mit der bisherigen auf der Grose der Chromosomen beruhenden cytologischen Numerierung (Rai, 1963; Dennhofer, 1968) uberein. Das kurze Chromosomenpaar (I) tragt die geschlechtsbestimmenden Faktoren M bzw. m und die geschlechtsgekoppelten Gene der 1. Koppelungsgruppe. Das mittellange Paar (II) entspricht der 2. Koppelungsgruppe, der die Augenfarbmutation ruby (Iltis, Barr, McCelland und Myers, 1965) angehort. Die ungefahre Lokalisierung dieses Allels wird diskutiert. Das langste der Homologenpaare (III) ist der 3. Koppelungsgruppe gleichzusetzen, der z. B. die mannchenbegrenzte Palpenmutation kps (Laven, 195…
