Southern anthracnose is caused by the fungal pathogen Colletotrichum trifolii Bain et Essary and affects red clover (Trifolium pratense) cultivation, causing severe losses in plant stands. Artificial inoculation with greenhouse has been proven to effectively differentiate varieties for their resistance based on survival rates of plants. Additionally, this method was successfully used improve po...

We use a new method of analysis to determine parameters of cosmological gamma-ray bursts (GRBs), assuming that their distribution follows the star formation history of the universe. Spectral evolution is calculated from an external shock model for Ðreball/blast-wave evolution and used to evaluate the measured peak Ñux, duration, and peak photon energy for a GRB source occurring at a given redsh...

GRB 990123 was the Ðrst burst from which simultaneous optical, X-ray, and gamma-ray emission was detected ; its afterglow has been followed by an extensive set of radio, optical, and X-ray observations. We have studied the gamma-ray burst itself as observed by the Compton Gamma Ray Observatory detectors. We Ðnd that gamma-ray Ñuxes are not correlated with the simultaneous optical observations a...

In this review, we consider the impact of magnetic field on properties strongly correlated heavy-fermion compounds such as metals and frustrated insulators with quantum spin liquid. Magnetic B can be considered a universal tool, allowing exploration physics controlling remarkable compounds. These vivid are T/B scaling, exhibited under application at fixed temperature T, emergence Landau Fermi l...
