<p>There has long been interest in the sources of ionospheric variability, especially in how this variability can be caused by the dynamics of the neutral atmosphere. Many studies have found planetary wave fluctuations in ionospheric parameters, especially f0F2, with periods ranging from 2 to 20 days. We investigate variations of the geomagnetic field and critical frequency of the F2-layer in the range of planetary waves in winter. We used the data of geomagnetic monitoring at the Central Geophysical Observatory at Belsk of Institute of Geophysics of the Polish Academy of Sciences (Poland, Belsk) and the results of high-frequency sounding of the ionosphere in the form of ionograms obtained by the Space Research Center of the Polish Academy of Sciences (Poland, Warsaw).  In the spectra of temporal variations of the geomagnetic field and the critical frequency of the ionospheric F2 layer in the range of planetary waves periods in winter season, we found both harmonics associated with the modulation effect of longer-period (annual and 11-year) variations and tidal effects, and a harmonic corresponding to a quasi 16-day planetary wave. Possible mechanisms of their manifestations in the upper atmosphere are discussed.</p>

The aim of the study was to analyse the content of museum labels from various periods in terms of their usefulness in creating new labels for exhibits included in museum collections. Nearly 5,000 museum labels from the years 1811 to 2017 were reviewed, for exhibits at the Museum of Zoology of the Polish Academy of Sciences in Warsaw, Herbarium of the University of Wroclaw, and the Museum of Forensic Medicine at the Medical University of Wroclaw. On the basis of the collected information, an attempt was made to develop a ‘universal label’template, including a range of necessary information from the point of view of managing and maintaining the accessibility of the relevant collection.
