Assessing the Impact of Drought Stress on Hemp ( L.) Fibers.

Drought can significantly impact fiber crop cultivation due to the plants' specific water requirements and their extended vegetative period. The purpose of the research was to examine how drought stress affects the quality and chemical composition of hemp ( L.) fibers.

Development of a Layer Made of Natural Fibers to Improve the Ecological Performance of the Face Mask Type II.

The aim of this study was to develop a natural nonwoven layer made of cottonized bleached flax and cotton fibers which is suitable to replace one of the three polypropylene layers of face mask type II in order to reduce non-biodegradable waste production and limit the negative impact of used masks on the environment. The work focused on the design of a nonwoven structure based on properly blending cotton and flax fibers as well as ensuring the cover factor, which can support the mask's barrier properties against air dust particles and does not make breathing difficult. Additionally, a biodegradable film was developed to connect the nonwoven layer with the other polypropylene filtering layers.

Effect of Drought Stress on Quality of Flax Fibres.

Global warming has led to a change in climatic conditions. Since 2006, drought has contributed to a reduction of food production and other agriculture-based products in many countries. The accumulation of greenhouse gases in the atmosphere has caused some changes in the composition of fruits and vegetables, making them less nutritious.

Effects of Agricultural Management of Spent Mushroom Waste on Phytotoxicity and Microbiological Transformations of C, P, and S in Soil and Their Consequences for the Greenhouse Effect.

The huge volumes of currently generated agricultural waste pose a challenge to the economy of the 21st century. One of the directions for their reuse may be as fertilizer. Spent mushroom substrate (SMS) could become an alternative to manure (M).

Bioactive Hemp Clothing Modified with Cannabidiol (CBD) L. Extract.

Hemp fiber variety, Bialobrzeskie, contains phenolic acids in its chemical composition giving it inherent antioxidant and antibacterial activity. The use of this raw material in fabric manufacture allows the creation of functional clothing with a positive effect on human skin. The aim of the study was to develop biologically active functional clothing made of pure industrial hemp raw materials, where cannabidiol (CBD) extract applied on the fabric surface strengthened the fiber bioactivity.

Effect of reclamation treatments on microbial activity and phytotoxicity of soil degraded by the sulphur mining industry.

The aim of the work was to determine the trend, intensity and changes of selected microbial and phytotoxic parameters of degraded soil in the area of former sulphur mine reclaimed by post-flotation lime (PFL), sewage sludge (SS), mineral wool (MW- mixed with soil, MWP-pad) and mineral fertilizer (NPK). The following parameters: number of proteolytic bacteria and fungi, ammonification, nitrification, activities of alkaline phosphatase and arylsulphatase Lepidium sativum growth index (GI) and phenolic compounds were analysed in the soil in second and third year of the experiment. The addition of the SS separately or in combination with other remediation agents was found to be the most valuable for the number of microorganisms, intensification of nitrification process and enzymatic activities.

[The influence of the parents education on the frequency of vegetable and fruit consumption by their children].

Many different factors affect the way we eat. Extensive research shows that children and the young people consume too small quantities of fruits and vegetables. The purpose of work was examining the influence of the School Education on the consumption of vegetable and/or fruit consumption by their children.

[The role of glucosinolates in the prevention of cancer--mechanisms of actions].

Foods of plant origin, despite plenty of nutrients contain many non-nutrition compounds, which may prevent many diet-related non-communicable diseases, such as cancer. Plants produce thousands of phenolic compounds as secondary metabolites, such as nitrous compounds. Glucosinolates are responsible for the secretion of detoxifying enzymes that remove carcinogens for the organism.
