The transboundary Chorokhi River Valley, extending from the upper mountainous catchments of northeastern Turkey to the deltaic plains of Georgia, represents one of the most ecologically diverse corridors in the eastern Black Sea Basin. This landscape integrates wetlands, river meanders, mixed and broad-leaved forests, agroforestry systems, and coastal dunes that together sustain high biodiversity and essential ecological processes of the Colchic biogeographical province. An integrated landscape–ecological approa...

The wealth of the bowels of Kazakhstan has not yet been exhausted, there are promising areas that are currently insufficiently studied, especially at depth. The reason for the insufficient knowledge of geological structures in depth is the lack of a theoretical basis for geological research and justification for the forecast of prospect for minerals. In this regard, geology faces the question of creating a scientific approach for predicting new prospect areas, especially at depth. Our analysis shows that the princ...

Granitoids are very developed and widespread geological formations on the territory of Kazakhstan. Many mineral deposits are associated with them, in addition, they themselves are useful minerals, like building materials. The Shu-Ile tectonic belt in Kazakhstan is a large region of the Paleozoic granitoid massif. Many deposits of gold, non-ferrous metals and rare earth elements are associated with them. One of them is the Jeltau leucogranites complex, with which most of the facing stone objects are associated. In ...

Many exploited mineral deposits are at the final stage of development. The depletion of mineral reserves leads to a reduction in the volume of production and output, as well as to the social tension of single-industry towns, whose activities are directly dependent on the mining and processing industries of the economy. In our research, the initial data are the materials of geological observations and testing of tailings storages of the copper ore beneficiation factories of Kazakhstan. Studies on the composition an...

The Shu-Ile tectonic zone is located along the Jalaiyr-Naiman deep fault (geosuture). It stretches in a northwestern direction, passing in the northern part of the territory into a submeridional direction. It stretches in a narrow strip of about 600 km and is a section of the second ring structure of Kazakhstan. Deposits and occurrences of iron, chromium and non-ferrous metals, gold and rare metals are associated with this geosuture zone. In general, the tectonic structure of the area is quite complex due to the d...

For prospecting works on the Karsakpai-Ulytau area, we used computer modeling of geological structures and a forecast of possible associated minerals. The Karsakpai- Ulytau ore district is located in the ring geosuture zone of Kazakhstan, represented by deep faults and crushing zones, which served as channels for the penetration of mantle melts into the Earth's crust. The area has a complex geological history. The combination of igneous, metamorphogenic and sedimentogenic geological formations of the Proterozoic a...

Cyanobacteria are ancient photosynthetic organisms that under certain conditions (high temperature, eutrophication) can grow rapidly and form "cyanobacterial blooms". Very often, these blooms are accompanied by production of cyanotoxins, which in most cases are dangerous to the other organisms. Knowing the producers of cyanotoxins is of utmost importance, especially today when climate change has been shown to increase the frequency of toxic cyanobacterial blooms worldwide. The aim of the present study was to chara...

Organic waste has been discharged into the environment by various industries in a global society. Anaerobic digestion has proven its potential as a waste-to-energy (WTE) technology to produce biogas, which can also replace fossil fuels while accommodating these unwanted wastes. However, there are limitations to anaerobic digestion, such as poor biomethane yield due to limited supply and fluctuations in the composition of the substrates, and an inadequate C/N ratio in the feedstocks. This paper aims to discuss poss...

The significance of organic plant growth stimulants, in the development of sustainable agriculture and increasing the fertility of degraded soils has sparked the interest of scientists and practitioners working in the field of agriculture in recent decades. On the world market, there are numerous plant growth biostimulants of various origins and compositions, as well as numerous research analyzing their impacts and roles. The study aimed to determine the novel biological activity of the new Georgian biostimulants ...

Cyanobacteria are a diverse group of photosynthetic bacteria found in a wide variety of habitats where they play crucial roles. They are one of the most morphologically diverse groups. The evolutionary relationships and the classification are poorly understood. The whole genome sequencing added a new dimension to our understanding of genomes of cyanobacteria and the genome-based phylogeny came into existence. The aim of this study was to conduct a genomic comparison of phylogenetically closely related filamentous ...

The subsoil use currently constitutes the basis of real sector of the Kazakhstan's economy. Therefore , the state programme "Digitalization of Kazakhstan" covers the geological sector of our country, and this predetermines a new approach to the methodology of geological exploration of mineral deposits. Implementation of the new approach to geological research is carried out with the help of modern innovative technologies, such as Mapinfo, Arcgis, GIS-Micromine, where the scientific digital information base of geol...

Rare metal deposits, spatially and genetically associated with leucocratic and alaskite granites of the Permian age, are confined to their dome parts and apophyses. According to researchers, the formation temperatures of granitoid intrusions are determined within 890-7500C. The actual data indicate that the formation of these deposits is greatlyinfluenced by conductive heat flow from the cooling ore-bearing intrusive massif,leading to redistribution of temperatures in the near-intrusive space, resulting inemergenc...

Cyanobacteria are the oldest prokaryotes with worldwide distribution. Some of them are able to produce secondary metabolites (including cyanotoxins), which can have different effects on the other phytoplankton species. It is speculated that production of cyanotoxins is an adaptation mechanism of the cyanobacteria to survive in diverse habitats inhibiting the growth of the competing aquatic biota. In certain environmental conditions, bloom forming cyanobacteria may exert rapidly their allelopathic potential and cha...

Development of new nanostructured carbon sorbents with desired properties is an important task. This corresponds to the carbon-containing sorbents, i.e. active alternative coals, because their usage puts forward increasingly stringent requirements to their strength and structural characteristics. Determination of active centers in sorbents, understanding of mechanisms, which form coal-mineral sorbents, allow to make process of synthesis controlled, and thus provides obtaining of carbon-containing sorbents with cer...

During combustion of natural fuels together with oxides of main fuel elements (carbon and hydrogen) fly ash with unburnt fuel particles, sulfur oxides, nitrogen oxides, some amount of fluorine-containing compounds and gaseous products of incomplete combustion of fuel are released into the atmosphere. The technology and technological parameters of equipment for purification of exhaust gases of TPP, which allows to remove up to 95% of sulfur and carbon oxides by low-temperature liquid-phase catalytic oxidation at at...
