We present a unified model for optical, ultraviolet (UV), and X-ray light curves of V1974 Cygni (Nova Cygni 1992). Based on an optically thick wind model of nova outbursts, we have calculated light curves and searched for the best fit model that is consistent with optical, UV, and X-ray observations. Our best fit model is a white dwarf (WD) of mass 1.05 M⊙ with a chemical composition of X = 0.4...

Many fungal genera have been defined based on single characters considered to be informative at the generic level. In addition, many unrelated taxa have been aggregated in genera because they shared apparently similar morphological characters arising from adaptation to similar niches and convergent evolution. This problem is aptly illustrated in Mycosphaerella. In its broadest definition, this ...

Abstract Ramularia leaf spot is a major economic disease of barley caused by the dothidiomycete fungus collo-cygni. The has complex life cycle which includes extensive late season spore release events and seed-borne phase. Predicting epidemics during growing remains difficult challenge. To better understand interaction between movement epidemics, samplers were set up in Germany (2 sites over 4 ...

Abstract Ramularia leaf spot disease (RLS) is one of the most dominating fungal diseases in barley. The typically appears late season after flowering and results a rapid loss photosynthetic area. A recent decline fungicide efficacy lack RLS-resistant cultivars hamper effective control. Global warming will provoke increasing droughts which influence host plant physiology probably affect outbreak...

The disease pressure from Pyrenophora teres, Rhynchosporium graminicola, and Ramularia collo–cygni varies widely between years locations, which highlights the need for using risk models to avoid unnecessary use of fungicides. Three were tested in thirty–three field trials during two seasons five countries order validate identify situations favourable barley leaf blotch diseases Nordic–Baltic regi...

We present simultaneous X-ray and radio observations of the black hole X-ray binary V404 Cygni at the end of its 2015 outburst. From 2015 July 11–August 5 we monitored V404 Cygni with Chandra, Swift, and NuSTAR in the X-ray, and with the Karl G. Jansky Very Large Array and the Very Long Baseline Array in the radio, spanning a range of luminosities that were poorly covered during its previous ou...

Interaction among nitrogen fertilization using bovine manure, poultry Jatropha curcas seed cake and urea, the diseases Ramularia leaf spot (RLS) Boll rot (BR), caused by Ramulariopsis pseudoglycines Diplodia gossypina, respectively, in cotton plants (Gossypium hirsutum L.), was studied under field conditions. Intensity (incidence severity percentage) of RLS incidence (%) BR were evaluated over ...
