The main goal of the investigation was to compare the efficiency of using inquiry-based activities in teaching selected...

The article presents the ongoing research, which aims to select suitable electrodes and mixtures of conductive inks, which will be used as a converter between the pressure and electrical quantities in the design of planar pressure transducers. In the described research, we continue our previous work and the work of other authors who have previously...

An increase in the share of renewables in heat supply systems is a promising direction to reach sustainable development goals and decarbonization. Decision makers should consider various factors, including energy market prices, the availability of biofuels, boiler and auxiliary equipment costs, logistic costs, and the taxation system. In the Europe...

Bark stripping by red deer (Cervus elaphus L.) is one of the most acute instances of damage wrought by these animals in a forest. Because of its location, bark stripping causes damage to the thickest and most valuable part of the tree trunk, which lowers the quality of the wood due to technical flaws. The research was conducted in 25 sampling sites...

The trees (e.g., fruit or decorative) growing on the homestead plots of private households provide opportunities for sustainable biomass obtained from pruned branches every year. Profitable production of fuel material requires high-performance equipment and methods by which wood chips can be produced at low cost. The practice of chopping tree branc...

The assessment of the surface area of all leaves from a tree crown is regarded as one of the key parameters in scaling ecophysiological processes, such as growth, carbon budget, and water management. The purpose of this study was to investigate the variation of the mass and surface area of Scots pine needles, obtained from trees growing in the same...

In the last ten years, many countries around the world recorded a new disease of the Cucurbitaceae, the agent of which was P. melonis. The ability of P. melonis 502 to form intracellular mycelium in the epidermal and parenchymal tissues of roots was shown. Leading tissues (xylem and phloem) did not colonize, which indicates the impossibility of pla...

The accumulation of various types of waste containing both organic and inorganic metal-containing compounds is extremely hazardous for living organisms. The possibility of polymer degradation, biohydrogen synthesis, and metal detoxification via the dark fermentation of model potato waste was investigated. For this purpose, the strict anaerobic stra...

The European Union has set targets for renewable energy utilization. Poland is a member of the EU, and its authorities support an increase in renewable energy use. The background of this study is based on the role of renewable energy sources in improving energy security and mitigation of climate change. Agricultural waste is of a significant role i...

The aim of the study is to present a methodology for analyzing pollution emissions in a medium-sized city using modern traffic simulations in the aspect of minimizing exhaust emissions. The scope of the research and the methods of analysis used differ from those applied in big cities projects that can be found in the literature, Therefore the progr...

The depletion of fossil fuels and climate change concerns are drivers for the development and expansion of bioenergy. Promoting biomass is vital to move civilization toward a low-carbon economy. To meet European Union targets, it is required to increase the use of agricultural residues (including straw) for power generation. Using agricultural resi...

The article deals with a piezoelectric force sensor, that bases on the use of piezo ceramics PZK 850. These types of sensors were used due to characteristic of the piezo-material (i.e. crystal) particularly for dynamic force measurement only. The developed sensor is suitable to measure static forces up to 50 N; the principle of the measurement of s...

The article describes the ways and scope of using digital technologies by Polish seniors. Older people are commonly considered to be digitally excluded people, and thus have difficulties with using the Internet and the equipment that is used to connect to it. The article presents a selective review of research that seems to contradict the thesis on...

Učivo o technice a technologiích je v celosvětovém měřítku neopomenutelnou součástí školního vzdělávání na základních školách. Zahrnuje nejen poznatky o tradiční technice, postupech zpracování technických materiálů a užívání techniky, ale i o moderních zařízeních, digitálních technologiích a robotice. Nejedná se však jen o poznatky, smyslem je i po...

Numerical simulation of technological processes enables their exact description and it makes possible to get closer to the real process courses. The described method uses mathematical models transformed into the finite element method. The processes of interaction of the laser beam with the surface of austenitic stainless steel are first observed on...

The inclusion of pupils into schools of main educational stream is emphasized at the international level. Recently, this trend is more strongly applied in post-communist countries, where the now-criticized approaches, based on the exclusion of pupils with mild intellectual disability and behavioural disorders (ADHD) and their inclusion into special...

The inclusion of pupils into schools of the main educational stream is emphasized at the international level. Recently, this trend is more strongly applied in post-communist countries, where the now-criticized approaches (based on the exclusion of pupils with mild intellectual disability and behaviour disorders – e.g. ADHD – and their inclusion int...

The contemporary tendences emphasize the use of so-called inquiry-based learning (IBL). However, there remains a question – by which ways should be the active inquiry of pupils induced? The author of this article finds the answer in the union of the theory learning tasks and theory of the inquiry-based instruction. Via the analytical and comparativ...

The inclusion of pupils into schools of main educational stream is emphasized at the international level. Recently, this trend is more strongly applied in post-communist countries, where the now-criticized approaches, based on the exclusion of pupils with mild intellectual disability and behavioural disorders (ADHD) and their inclusion into special...

The article presents results of the granulometric composition of chip particles when sanding wood (beech) and wood-based materials (particleboard and semi-hardboard) using different types of sanders – wide belt sander, narrow belt sander, and hand sander. On the basis of the carried out sieve analyses, the proportion of produced particles, which ca...

Experimental research focused mainly on assessing the possibilities of energy savings in a manufacturing process through shortening a technological process of moulding. By optimalisation of a...

Due to relatively low environmental awareness of a man, we have reported considerable deterioration of the environment on the Earth resulting mainly in destruction of the nature. In general, increasing people ́s awareness along with conscious environmentally-responsible behaviour may help slow down the process of degradation or even stop it. Conseq...
