Artificial intellect models (machine learning, logical reasoning, etc.) are currently the focus of many remote sensing approaches for forest inventory management. Although they return satisfactory results in many tasks, some challenges remain, especially in the case of the highly dense distribution of trees in forests. In this paper, we propose a n...

As many tree species populations are being degraded by climate change, adaptive conservation, and forest management, such as assisted gene flow (AGF), can provide the genetic variation needed to adapt to climate change. The core of this strategy is to assist the adaptation process in populations at risk of climate maladaptation by introducing indiv...

Due to global climate cooling and aridification since the Paleogene, members of the Neogene flora were extirpated from the Northern Hemisphere or were confined to a few refugial areas. For some species, the final reduction/extinction came in the Pleistocene, but some others have survived climatic transformations up to the present. This has occurred...

The climate drives species distribution and genetic diversity; the latter defines the adaptability of populations and species. The ongoing climate crisis induces tree decline in many regions, compromising the mitigation potential of forests. Scientific-based strategies for prioritizing forest tree populations are critical to managing the impact of...

Tea is one of the most consumed beverages, second only to water worldwide. It stands out for its taste, aroma, and other benefits. Tea contains large amounts of phenolic substances with high antioxidant properties. Tsalenjikha green tea was selected for the experimental study. Three types of extracts were chosen: deionized water, ethanol and a mixt...

Due to the industrial processing of grapes, large amounts of by-products are produced. The main varieties of by-products are pomace, which is comprised of skins, seeds and any other solid remaining after pressing process and sediments. It is necessary to implement new effective ways of processing to minimize these residues. This problem is relevant...

Scots pine is one of the most widely occurring pines, but future projections suggest a large reduction in its range, mostly at the southern European limits. A significant part of its range is located in the Caucasus, a global hot-spot of diversity. Pine forests are an important reservoir of biodiversity and endemism in this region. We explored demo...

Plant extracts used in food production significantly improve the quality of food. Chemical composition is the main prerequisites for the final use of plant extracts. The chemical composition of the extracts is affected by the extraction method and conditions - temperature, duration and solvent. On the basis of experimental data optimal conditions f...

oiron-containing adsorbents have been widely used for cleaning of waters contaminated with organic and inorganic pollutants. Nanoiron can be spread over an organic and inorganic liner. Using renewable bioresources (timber, agricultural wastes, waste of biotechnological processes, etc.) to obtain sorbents containing nanoiron and iron oxide is quite...

Iron compounds [FeCl3.6H2O), Fe(NO3) 3.9H2O,Fe(CO)] were impregnated in timber samples. Iron ion impregnation was performed for 48h. The penetration of ions into the wood is carried out through capillaries (xylems). The method of energy dispersion X-ray analysis showed that during impregnation of FeCl3 and Fe(NO3) 3, the iron content in the wood re...

Zero-valent iron nanoparticles (ZVI) are widely used to remediate groundwater and stream water from heavy metals and stable organic pollutants (Permeable Reactive Barriers). Especially noteworthy is the fact that Fe0 reduces several halogenous hydrocarbons, chlorine-containing pesticides, organic dyes, nitrozo compounds, explosives and others. The...
