The studies on bird mortality along 12 transparent acoustic barriers near roads in Bielsko-Biala (Poland) were conducted from March to October in 2017. The aim was to characterize avifauna striking glass barriers and to relate frequency of collisions to time, developmental stage, sex, vicinity of noise barrier. During the breeding season of birds, 102 collisions of birds with screens, belonging to...
The paper presents the assessment of the water condition of the Łękawka stream according Water Framework Directive, carried out on the basis of research on benthic macroinvertebrates and the analysis of data on other indicators used in the monitoring of waters. Sampling of macroinvertebrates, taxonomic identification and calculation of the MMI_PL index were carried out in accordance with the Multi-Habitat...
The formation of sludge is an inevitable consequence of wastewater treatment processes and their disposal and utilization requires knowledge, technology and engineering. Sulfate radical-based advanced oxidation processes (SR-AOPs) are gaining popularity as a feasible alternative for sludge conditioning and removing recalcitrant pollutants in an aqueous environment. Application of the pretreatment...
Frequent exceedances of permissible PM10 concentrations occur mainly during the so-called heating season and are readily noticed not only by environmental protection specialists but al-so by residents; they are also wildly discussed in the mass media. If the state of elevated concentrations persists for at least several hours, it is generally referred to as smog. The duration of smog can range from...
The extraction of minerals, including fossil fuels, is a licensed activity. In the case of strategic fossil fuels owned by the state, such as hard coal, lignite, crude oil, natural gas, a license is issued by the minister responsible for the environment. The minister also signs a mining lease agreement, that is the right to use a mining area, with the entity to which they grant the licence. In the...
The article describes the research on the retention capacity of two mountain catchments in the Polish Carpathian Mts. These are the catchments of the Czarna Woda and Biała Woda streams. These catchments are adjacent, have a similar area (about 11 km2 each), but are geographically diverse. Their geomorphology, hydrographic network, soil water permeability and land use were analyzed. The Czarna Woda...
Soil organic matter content (SOM) is used e.g. in soil classification and erosion evaluation. However, its value depends on soil specimen preparation and test method so it is useful to deal with these issues. Totally 150 specimens of soils CI, MS (from Bielsko-Biała, Poland) and different 3 soils, all classified as GC (from Ujsoły, Poland) were tested. To obtain values of SOM, the oxidation method...
Perovskite cells are a new generation of solar cells that have gained significant attention in the field of photovoltaics due to their unique properties and potential benefits. Perovskites are a class of materials that have a characteristic crystal structure known as the perovskite structure. The typical chemical formula of perovskite is ABX3, where 'A' and 'B' are cations that differ in size, and...

The most important from the...
The impact of organizational behavior on the effectiveness of quality management is an important research area undertaken by many researchers over recent years. Research shows that employee behaviors such as commitment, communication, motivation and teamwork influence the quality of products or services offered by the company, and thus customer satisfaction. In the light of conducted research, adopting...
Parks are undoubtedly areas of great natural value to the city, mainly due to the ecosystem services and ecological functions they provide. An important component of every park is its forest stand.
