In recent years, the Budryk Coal Mine (KWK Budryk) reached the mining depth of 1300 m, where there is about 160 million tons of coal, including 120 million tons of coking coal (type 35). The task of the Coal Processing Plant complex modernization was undertaken. The article presents the modernization of coal screening, classification and dewatering systems at the KWK Budryk Processing Plant and the implementation of screening of PROGRESS ECO sp. z o.o. SK. The modernization project defined the following technical requirements for all screens in the KWK Budryk Coal Processing Plant extension project:

- Vibrating screens with a linear type drive with a drive unit placed on the drive beam of the trommel screen in the form of vibration generators;

- Screen drives equipped with a starting-braking device;

- The use of main screen drive bearings with a nominal service life of at least 40,000 man-hours;

- All work surfaces made of materials with a strength of up to 80 mm grain and abrasion resistance; side strips and sieves fixed in a way ensuring trouble-free operation, and at the same time quick and easy replacement;

- Sheets made of stainless steel;

- Side walls, beams and other elements attached to them connected with screws using a system protecting against corrosion and elements separation;

- The use of a work parameters monitoring and visualization system, i.e.

- pitch of the riddle,

- bearing operating temperatures and the condition of their wear.

Three types of screens were provided:

- PWP1-1Z-2,8x6,0 screeners that alternatively perform sieving or desliming processes,

- PWP1-2.4x6.0 screening machines performing desliming processes,

- PWP1-2.0x6.0 screens performing the classification process.

The article discusses the use of metaphors in the terminology of astronomy and astrophysics. The terminology of these fields is relatively stable, characterized by terminological diversity, thus allowing to draw sufficiently general conclusions. Three cases are to be considered: (a) first, the metaphor as a powerful source of terms, assuming the denominative function, (b) the terminological metaphor which leaves a certain domain and which penetrates into the general language, which is sometimes called determinologization, and, (c) finally, the terminological metaphor migrating from one specialized domain to other terminologies in which it is newly used to denote another concept, this phenomenon sometimes being referred to as transterminologization. The three processes are analysed and documented, using French and Czech examples, excerpted from specialised texts (encyclopaedic dictionary and newspaper articles).

Introduction: Screening sinonasal evaluation is routinely performed before allogeneic hematopoietic cell transplantation (allo-HCT), however, data supporting such evaluation is inconsistent.
Objectives: Assessment of the utility of screening sinonasal evaluation with computed tomography (CT).
Methods: A retrospective analysis of acute leukemia patients who underwent allo-HCT, for whom screening sinonasal CT scans were reevaluated, and for whom Lund-Mackay score (LMS) was calculated.
Results: Forty-eight patients, the median age at allo-HCT 38 years (18–58), 52% males, were included. 79% had acute myeloid leukemia (AML), 21% acute lymphoblastic leukemia (ALL). Conditioning inten-sity was myeloablative in 96% of patients, 21% of patients received total body irradiation. 19% of patients had a history of sinusitis before allo-HCT. Screening sinus CT was performed a median of 22 days before allo-HCT. The median LMS was 1 point (0– 10). The severity of sinus abnormalities was: no abnormalities (31%), mild (67%), moderate (2%), severe (0%). Mucosal thickening was the most frequent abnormality (69%). Eleven patients experienced sinusitis after a median of 93 days (11–607) after allo-HCT. 1-year cumulative incidence of sinusitis was 22%. No threshold of LMS and no type of sinus abnormalities were correlated with sinusitis development after allo-HCT. Mild sinus disease at screening did not negatively impact survival in comparison to no sinus disease.
Conclusions: Despite the fact, that majority of analyzed patients had either no or mild sinus disease at screening a significant proportion of patients developed sinusitis after allo-HCT. Evaluation of LMS before allo-HCT did not help predict the development of sinusitis after the procedure.

Arterial stiffness is a characteristic of the arterial wall strongly associated with ageing and hypertension. It has been confirmed as a significant cardio-vascular risk factor. Despite available non- invasive measurement methods of central artery stiffening, it has not become a prevalent diagnostic marker in primary care so far. This article provides an overview of pathophysiology of arterial stiffness, possible diagnostic techniques, association with cardiovascular conditions and potential perspective of primary care to implement an additional distinctive parameter to evaluate cardiac risk.

The epidemic process of COVID-19 in the world developed rapidly. The situation with mor-bidity, despite the establishment of quarantine, the introduction of restrictive anti-epidemic measures, and vaccination, remains difficult. The results of research on the influence of meteorological factors on the dynamics of the incidence of COVID-19, hospitalization, and mortality are ambiguous and contradictory. The purpose of this study is to analyze the indicators of morbidity, hospitalization, and mortality from COVID-19 in Ukraine, and to establish the level of influence of meteorological factors on them. A high variation in morbidity, hospitalization, and mortality rates was observed in Ukraine, in 2020–2021. A total of 3 waves of disease growth were established. The curve of hospitalization indicators of patients with COVID-19 had a correlation dependence on the incidence curve r = 0.766 (р <0.05), the maximum rates of hospitalization and mortality were registered in September–December 2021. A direct strong correlation was established between the frequency of registration of cases of COVID-19 and mortality — r = 0.899 (р <0.05). Most cases of COVID-19 were registered in the cold season, the least in June–August. Inverse correlations of moderate strength were established between the indicators of morbidity, hospitalization, and mortality and air temperature levels (–0.370< r <–0.461). Direct correlations of average strength (0.538< r <0.632) were established with the levels of relative air humidity.

The paper presents results of studies focused on occurrence and correlation of four main horizons of Younger Loesses: Lowest Younger Loess (LMn – after Maruszczak, 2001), Lower Younger Loess (LMd), Middle Younger Loess (LMs), and Upper Younger Loess (LMg) recorded in five sections (Politów, Wąchock, Nietulisko Małe, Komorniki and Bodzechów) in the Holy Cross Mountains area. All analysed loesses were accumulated during the Vistulian Glaciation (Weichselian). The horizons were distinguished based on separating interstadial tundra soils, coupled with thermoluminescence dating, and correlated with marine oxygen-isotope stages MIS 5d−2. The Lowermost Younger Loess (LMn) covers the Nietulisko I soil complex (Jersak, 1973), developed on deposits of the Odranian Glaciation (MIS 6) and representing a forest soil of the Eemian Interglacial (MIS 5e) and the Brørup warming (MIS 5c). A thin horizon of the Oldest Younger Loess and a thin sandy horizon, both probably corresponding to the Herning cooling phase (MIS 5d) at the boundary with the Eemian Interglacial, were distinguished within this complex. Based on previously performed grain-size and heavy mineral analysis of the Upper Younger Loess (LMg) and a topographic position of the loesses in four loessy islands of diverse regional extent, accumulation of this loess in the Holy Cross Mountains area is found to have been stimulated by the western winds. The proposed model of loess accumulation takes into account the influence of the topography of the area and its geological structure.
