Suitability of engineering-geological environment on the basis of its permeability coefficient: Four case studies of fine-grained soils

The aim of the article is to compare two classifications systems of engineering-geological environment sustainability in terms of its permeability evaluated on the basis of permeability coefficient. The first evaluated classification assumes a permeable environment to be a positive characteristic in the engineering-geological assessment, while the other considers an impermeable environment as favourable. The four fine-grained soil materials were selected, as they had very similar, almost identical grains-size distribution, but different microstructure characterized by grains sphericity, angularity, and roughness. At the same time, the influence of changes in the density of soil materials (density index 10%, 30%, 60%, 90%) was analysed. Permeability coefficient was determined using six methods (empirical formulae, laboratory and microscopic analysis). The laboratory method falling head test (FHT) was taken as a reference test that reflected the actual water flow through the soil. It was found that with an increase in grain angularity and roughness (and a decrease in sphericity), the permeability coefficient was decreasing and this trend culminated along with gradual compaction. Moreover, the research shows that unsuitable methods may classify soil materials into wrong engineering-geological permeability classes, which may have negative consequences during engineering-geological or geotechnical assessment and cause subsequent problems in foundation engineering.Web of Science1421art. no. 641

Integracja finansowa w Europie po wprowadzeniu euro. Przegląd literatury

The introduction of the euro was one of the most important events in the process of European integration, especially in the financial sector. However, next to its many advantages, the joint currency and single monetary policy increased the probability of property bubbles in the EU low income countries. The excessive speculations, which resulted in the burst of the US property bubble, the financial crisis, as well as the fiscal problems and the recession in Europe in 2010, uncovered the weaknesses of the financial integration and the inability of the European financial system to absorb large shocks. The financial losses, and the risk that some banks and moreover, even some euro zone member countries might become insolvent, underlined the existence of large systemic risks. As a result, cross border lending declined, the European credit market was affected negatively and the uncertainty concerning the stability of the euro increased. The second phase of the crisis in Europe was a starting point to develop some new international solutions to those problems aimed at increasing the stability of the European financial system. Our paper presents an overview of the literature on the advancement of financial integration in the euro zone, as well as in other regions including Poland. The concluding part of this review summarizes also the results of own research of its authors

Neurological symptoms in hospitalised patients with COVID-19 and their association with in-hospital mortality

Objectives. To evaluate the spectrum of neurological symptoms in patients with COVID-19 during the first 14 days of hospitalisation and its association with in-hospital mortality. Material and methods. We included 200 patients with RT-PCR-confirmed COVID-19 admitted to University Hospital in Krakow, Poland. In 164 patients, a detailed questionnaire concerning neurological symptoms and signs was performed prospectively within 14 days of hospitalisation. In the remaining 36 patients, such questionnaires were completed retrospectively based on daily observations in the Department of Neurology. Results. During hospitalisation, 169 patients (84.5%) experienced neurological symptoms; the most common were: fatigue (62.5%), decreased mood (45.5%), myalgia (43.5%), and muscle weakness (42.5%). Patients who died during hospitalisation compared to the remainder were older (79 [70.5–88.5] vs. 63.5 [51–77] years, p = 0.001), and more often had decreased level of consciousness (50.0% vs. 9.3%, p < 0.001), delirium (33.3% vs. 4.4%, p < 0.001), arterial hypotension (50.0% vs. 19.6%, p = 0.005) or stroke during (18.8% vs. 3.3%, p = 0.026) or before hospitalisation (50.0% vs. 7.1, p < 0.001), whereas those who survived more often suffered from headache (42.1% vs. 0%, p = 0.012) or decreased mood (51.7% vs. 0%, p = 0.003). Conclusions. Most hospitalised patients with COVID-19 experience neurological symptoms. Decreased level of consciousness, delirium, arterial hypotension, and stroke during or before hospitalisation increase the risk of in-hospital mortality

A Wavelet Analysis of the Exchange Rate of the Zloty

The paper looks at currency exchange rates through the lens of a mathematical procedure known as a wavelet analysis. The authors use two statistical parameters, the Hurst coefficient and the gamma coefficient, to determine the compliance of their method with what is called Generalized Pareto Distribution (GPD). The Hurst coefficient is a measure of the randomness of a process and shows how it changes. The gamma coefficient provides information on the dependence/independence of variables generating the process. In the case of currency exchange rates, the main variables are key economic factors and decisions made by monetary policy makers. The analysis applies to a period in the past when Poland’s exchange rate system became more flexible. Depending on changes made in the exchange rate system, the authors identified periods of a uniform exchange rate policy and the stage of a free market rate. They zeroed in on daily changes in the dollar/zloty and euro/zloty rates, in addition to other factors
