Abstract

Small as they are, such deformation structures occur in extensive clusters. They can provide valuable geological information and may pose a challenge for prospecting engineers.

Abstract

The herbaceous understory is the lowest, ground-level layer of plants and fungi in the forest. What is its role and importance in the main ecological processes occurring in forest ecosystems?

Abstract

Fossils are a source of great interest, even fascination. They offer evidence of the past existence of living things, somewhat different from life as we know it today. Yet not many fossil-hunters realize that these traces of a bygone past are often a source of radiation.

Abstract

The Polish language is slowly disappearing among the Polish community in Ukraine’s Rivne Oblast. This is due to the influence of the clergy and the emigration of the younger generation.

Abstract

Water reaches a river in the form of surface runoff (precipitation that has not seeped into the ground) or underground outflow (groundwater). Both of these factors affect the erosion and river deposition processes that shape the river valley. Understanding them is crucial for effective river management.

Abstract

Drought is characterised as a recurring climatic phenomenon with prolonged duration, affecting land through below-average rainfall and often accompanied by high temperatures. When the available water falls below the optimum level, water deficit or water stress arises, disrupting normal plant processes. This condition poses challenges for plant growth and development as it hampers the internal water transport, induces stomatal closure, and limits access to photosynthetic resources.
The study employed the annual sunflower as the experimental plant. The plants were cultivated in a controlled environment with a temperature ranging from 20 to 25°C and a humidity level of 55 to 60%, supplemented by MARS HYDRO artificial LED lighting set to a 12-h photoperiod. Radial changes in the plant stems were monitored using a DD-S type dendrometric sensor to measure radial fluctuations. The collected data were recorded in a dendrometric data logger DL 18. Data collection occurred at hourly intervals from February 20 to March 9, 2023. The nine plants were divided into three groups, each comprising three plants. All plants from groups 1 and 2 received irrigation at one- day intervals (group 1 – 80 cm 3 per plant, group 2 – 40 cm 3 per plant) and group 3 was not irrigated.
Based on these findings, visible water stress was evident in the plants under experimental conditions. Consequently, continuous monitoring throughout the growing season will be essential to adjust the irrigation rate to meet the requirements of the plants.

Abstract

Choć są to niewielkie struktury deformacyjne, to występują w licznych nagromadzeniach. Zawierają w sobie cenne informacje geologiczne, a także stanowią wyzwanie dla inżynierów złożowych.

Abstract

Skamieniałości wzbudzają ogromne zainteresowanie, wręcz fascynację. Są dowodem istnienia dawnego życia, nieco innego niż obecne. Szukając śladów dawno minionej przyrody, nie zdajemy sobie sprawy, że skamieliny mogą być źródłem promieniowania.
