X-ray Sources and their Optical Counterparts in the Globular Cluster M4 [PDF]
, 2004 We report on the Chandra X-ray Observatory ACIS-S3 imaging observation of the Galactic globular cluster M4 (NGC 6121). We detect 12 X-ray sources inside the core and 19 more within the cluster half-mass radius. The limiting luminosity of this observation

Results of the Czech National Ring Tests of disease resistance in wheat
Czech Journal of Genetics and Plant Breeding, 2012 In this contribution actual results of the Czech national ring tests of disease resistance in wheat are presented that are performed at 3-5 locations each year. Special attention was paid to possibilities of increasing resistance to rusts, powdery mildew,

Theoretical Bases and Sources for Breeding Wheat for Combined Disease Resistance
Czech Journal of Genetics and Plant Breeding, 2005 Achievements and prospects of wheat breeding for disease resistance in the world and in theCzech Republic are discussed. Attention was paid to possibilities of increasing resistance to rusts, powdery mildew, Fusarium head blight, leaf blotch, glume ...

The possible companions of young radio pulsars [PDF]
, 1999 We discuss the formation of pulsars with massive companions in eccentric orbits. We demonstrate that the probability for a non-recycled radio pulsar to have a white dwarf as a companion is comparable to that of having an old neutron star as a companion ...

Analysis of Induction and Establishment of Dwarf Bunt of Wheat Under Marginal Climatic Conditions [PDF]
Plant Disease, 2011 Dwarf bunt caused by Tilletia contraversa is a disease of winter wheat that has a limited geographic distribution due to specific winter climate requirements. The pathogen is listed as a quarantine organism by several countries that may have wheat production areas with inadequate or marginal climate for the disease—in particular the People's Republic ...

Transferring useful rye genes to wheat, using triticale as a bridge
Czech Journal of Genetics and Plant Breeding, 2011 Rye has already proven to be a good donor of genes for improving important traits and diversity in wheat breeding. The agronomic advantages of wheat-rye translocations, as well as their detrimental pleiotropic effects,were shown to be dependent on the ...

, 2023 Dwarf bunt or stinking smut is a disease that impacted Utah winter wheat production in the 1930s, resulting in fields with 95% infections. Breeding and selection of resistant varieties has irradiated the disease. As organic production of winter wheat increases, selecting resistant varieties will become of utmost importance to prevent crop loss.

Untersuchungen zur natürlichen Resistenz verschiedener Dinkelsorten gegen Zwergsteinbrand [PDF]
, 2013 In inoculated field trials with dwarf bunt (Tilletia controversa) spelt wheat cultivars appeared more resistant than bread wheat cultivars. Among 10 spelt wheat cultivars, Tauro showed the lowest infection rates.

Quiescent Superhumps Detected in the Dwarf Nova V344 Lyrae by Kepler [PDF]
, 2010 The timing capabilities and sensitivity of Kepler, NASA's observatory to find Earth-sized planets within the habitable zone of stars, are well matched to the timescales and amplitudes of accretion disk variability in cataclysmic variables.
