The aim of paper is to investigate the impact of woody debris deposited on the river bed on the granulometry of the bed material. The analysis included upstream and downstream sides of the investigated woody debris. The investigations comprised determination of the geometric dimensions of the analyzed wood deposits, determination of the granulometric composition of the bed material in the area of deposition of woody debris, determination of the range of influence of the investigated woody debris on the bed material and determination of the relationship between the geometric dimensions of the woody debris and the extent of their impact on the bed material. The granulometric analysis was conducted using the conventional sieving method. The extent of the influence of woody debris was determined on the basis of the Nash’s-Sutcliffe’s efficiency coefficient. The dependence of the extent of wood influence and the dimensions of the investigated woody debris was determined on the basis of the Spearman’s correlation coefficient. It was found that the woody debris deposited on the bed of the Raba river affects the granulometry of the bed material on both the upstream and downstream sides. The study also showed that the extent of the impact on the grain-size composition of the bed material on the downstream sides of the woody debris is determined to a large extent by the height of the deposited woody debris.

The paper deals with the selected characteristics, such as moisture, average bulk density, and fraction size, of tropical marblewood dust (Marmaroxylon racemosum) that influence its ignition risk. Research was focused on sieve analysis, granulometric analysis, measurement of moisture level in the dust, and determination of the minimum ignition temperatures of airborne tropical dust and dust layers. Samples were prepared using a Makita 9556CR 1400W grinder and K36 sandpaper for the purpose of selecting the percentages of the various fractions (<63, 63, 71, 100, 200, 315, 500 μm). The samples were sized on an automatic vibratory sieve machine Retsch AS 200. More than 65% of the particles were determined to be under 100 μm. The focus was on microfractions of tropical wood dust (particles with a diameter of ≤100 µm) and on the impact assessment of particle size (particle size <100 µm) on the minimum ignition temperatures of airborne tropical dust and dust layers. The minimum ignition temperature of airborne marblewood dust decreased with the particle size to the level of 400 °C (particle size 63 μm).

The aim of this study was to identify the form of the dependence describing the relationship between rainfall (P) and the curve number (CN) parameter using the Natural Resources Conservation Service (NRCS-CN) method in the mountain catchments of the Western Carpathians. The study was carried out in 28 catchments areas in the Western Carpathians in the Upper Vistula Basin, Poland. The study was conducted in the following stages: determination of the volume of the direct runoff using the NRCS-CN method, determination of the P–CN relationship using asymptotic functions, kinetic equation and complementary error function; determination of the volume of the direct runoff from the catchment area, accounting for the correction of the decline; determination of the value of the efficiency coefficient of the analysed models. On the basis of the conducted study, a strong relationship was found between the direct runoff and the rainfall that caused it. The study showed that the empirical values of the CN parameter differed from the values determined on the basis of the volume of rainfall and runoff. The vast majority of study catchments were characterised by a standard P–CN relationship. The kinetic model was found to be the best model to describe the P–CN relationship. The asymptotic model showed the greatest stability for high rainfall episodes. It was shown that the application of the catchment slope correction improved the quality of the NRCS-CN model.

To determine the impact of influencing factors on unsupported roof stability in coal mine roadway, a mechanical model of the unsupported roof was built. FLAC 3D numerical simulation was utilized to study the stability of the unsupported roof under the influence of the depth of the roadway, the thickness of the roof, and the unsupported-support distance. In view of the key influencing factors, the geological conditions of the site, and the relationship between the tensile stress and tensile strength of the unsupported roof, the maximum unsupported roof distance during roadway excavation was determined. Considering the surplus safety factor of the unsupported roof, the reasonable unsupported roof distance during the excavation of roadway 150802 was finally determined to be 2.08 m. The comprehensive roadway excavation speed increased by 62.7%, achieving a monthly progress over 500 m.

The article discusses the problem of COPD combined with CAD, determination of inflammatory markers and the prognostic BODE, DOSE and ADO indices. The aim of the study was to evaluate the effect of PCV13 immunization on clinical and functional manifestations of systemic inflammation in patients with COPD and CAD, as well as the relationship with the prognostic markers. Material and methods: The study included 36 male patients with COPD and 36 patients with COPD and CAD, FC II-III stable angina who were treated at Regional Clinical Hospital _4 in Chelyabinsk during the period 2015--2016. Conclusions: 1. Patients with COPD combined with CAD had statistically significant clinical and functional disorders manifested by an increase in the degree of dyspnea and reduction in FEV1. 2. In patients with COPD concomitant with CAD, against the background of the comorbidities, the levels of systemic inflammation markers — C-reactive protein, fibrinogen and procalcitonin — were more overt than in patients only with COPD. 3. Monitoring changes in procalcitonin levels could be used as an additional highly informative method for estimating the probability of the presence of bacterial inflammation and effectiveness of therapy. 4. The prognostic BODE, DOSE and ADO indices tend to decrease unidirectionally under the impact of vaccination with pneumococcal conjugate vaccine. 5. PCV13 can reduce the level of systemic inflammation within 1 year after its application.

<p>This study examined the relationship between savings, investment and economic growth. A corollary of the work is the determination of which of the inputs of production contributes more to economic growth in Nigeria. The study makes use of time series data spanning twenty-nine years using error correction model. The result shows a positive relationship between savings, investment and economic growth in Nigeria. Of the determinants of savings considered in the study, inflation rate contributes negatively to saving, while interest rate positively affect saving. All these confirm economic theory. The striking feature of the study however is the confirmation of the impact of labour on economic growth, which according to the study far outweighs the contribution of capital.</p>

This article discusses the impact on patients of changes in copayments and safety net thresholds (SNT) within the Pharmaceutical Benefits Scheme (PBS). Trends in the nominal and real values of copayments and SNTs are examined, as are changes in the numbers of types of patients. The relationship between the number of safety net cardholders and copayments and SNTs is estimated. Increases in the number of copayments necessary to reach the safety net threshold restrict the number of patients able to benefit from this provision. Policy for determining the levels of copayments and safety net thresholds needs to be put on a rationale basis in a way similar to the determination of prices for PBS medicines.

The article examines some effects from the first approbation of a two-tier proportional system with „flexible” lists in the local elections in Ukraine in 2020. In the comparative-regional context, the impact of the new system on the increase in the number of invalid ballots is analyzed and the percentage of voters who exercised the right to preferential voting for a particular candidate from the district list of the elected party is calculated. Hypotheses about regional differences in these quantitative parameters are formulated: in particular, the share of invalid ballots may be influenced by ethnolinguistic and urban factors. It was found that about 80% of voters who took part in the autumn 2020 vote exercised the right to preferential voting by entering the number of a particular candidate on the ballot – this unexpectedly high figure is in the context of other national cases using proportional systems with „flexible” or clean „open” lists. Particular attention is focused on the relationship between the two levels of the electoral system – the single closed and district flexible lists, and, accordingly, the balance of influence of voters and party leaders on the passage of candidates to local councils. This ratio was calculated for all oblast councils, and the material of the Kharkiv and Lviv oblast councils determined the empirical probability of changing the order of candidates in the district party lists under the influence of voters. Although supporters and lobbyists called the introduction of a new electoral system in Ukraine a model with „open” lists, the article identifies two key institutional mechanisms for significantly downplaying the role of preferential voting in the final determination of candidates. It is argued that according to the results of the personal distribution of seats among the candidates in the party lists, this model of „flexible” lists was closer to the pole of „closed” than „open” lists. Keywords: electoral systems, electoral lists, Electoral Сode of Ukraine, proportional electoral system, „flexible” lists, preferential voting, invalid ballots.

Federal Center

The understanding the processes of decentralization of the economy in a federal state as one of the possible sources of economic development. This understanding requires the revision of the implications that the formation and implementation of a policy of relations between the federal center and the regions entails. The goal of our present research is to develop an approach that will help assess the impact of the nature of relations between the federal center and the regions on economic growth. The theoretical and methodological basis of this study is formed by a set of scientific concepts in the field of economic federalism and spatial analysis. Basing on the index method (by determining the values of decentralization of regional incomes and expenditures) and the implementation of positioning, an assessment was made of the relationship between decentralization and economic growth by such a resulting parameter of the development of the territory as the “growth rate of the gross regional product” and the parameter characterizing the development of federalism relations in the country as “the level of economic decentralization”. According of the calculations we prove there is a positive effect of decentralization processes on regional economic growth in the analyzed time interval. There is a greater impact on the processes of decentralization of the indicator of income decentralization compared to the decentralization of expenses. The results of our research can be used in the work of federal authorities in the formation of the regional component of federalism policy. It seems the proposed approach can basis of research related to the determination of the main directions of relations between regions and municipalities.
