Study reveals in detail the quiet Sun at low frequencies Calibrated interferometric images of the quiet solar corona on 07.08.2021 in low frequencies (24.60-78.90 MHz) observed by LOFAR. The Sun is an active star that has significant radio emission over a wide frequency range from kHz to THz, and the solar atmosphere has a complex distribution of magnetic field, plasma density and temperature. These different properties of the solar atmosphere lead to different radio emission characteristics at different frequencies. Interferometric imaging observations of solar low-frequency emission can help diagnose the properties of the plasma at high altitudes in the solar atmosphere. Calibrated interferometric images of the quiet solar corona on 14.08.2021 at low frequencies (24.60-78.90 MHz) as observed by LOFAR. In [...]

Second information day on the project “Centre of Competence HITMOBIL”

The Second Information Day of the “Centre of Competence HITMOBIL” Project, held on 21 June, brought together representatives of the project partners, the Managing Authority and businesses interested in the field of electrochemical systems for green energy. Corr. Mem. Evelina Slavcheva, Head of CoC HITMOBIL, presented the overall progress in the implementation of the three modules of the project: M1 - Industrial Research, M2 - Experimental Development and M3 - Dissemination and Technology Transfer. She summarized the achievements in the construction of the six laboratories under the first two modules (five of them already completed and the sixth under construction due to the complexity of the site).  Emphasis was placed on the infrastructure of the completed Laboratory 3 "Hydrogen and Fuel Cells" and the problems [...]

Third scientific conference “Innovative low-toxic biologically active systems for precision medicine (BioActiveMed)”

The scientific conference was held from 13 to 16 June 2022 at Park-Hotel Kyustendil within the framework of the National Scientific Programme "Innovative low-toxic biologically active substances for precision medicine (BioActiveMed)", with the leading organization Bulgarian Academy of Sciences and the financial support of the Ministry of Education and Science. More than 55 scientists participated and presented their interdisciplinary research conducted at seven institutes of the Bulgarian Academy of Sciences and five universities. The papers were divided into six scientific sessions which presented results on the preparation of new biologically active systems containing extracts from natural sources of plant or animal origin from Bulgaria, their antibacterial and antitumor activity, as well as their anti-infective effect. Results were also presented in two poster sessions. During the [...]
