Abstract:
This article examines the role of telemetry systems in improving the efficiency of technical asset management in the digital economy. Key factors in telemetry development are highlighted and the results of monitoring system implementation are summarized. It is shown that the integration of telemetry into technical systems management strategies is becoming a core component of digital transformation, with maximum efficiency achieved through end-to-end integration: from sensors and communication channels to storage, analytics, and organizational response procedures. Telemetry is transforming into a core digital management tool, ensuring a seamless process from assessing actual conditions to taking timely actions, surpassing the capabilities of one-time measurements. The use of time series storage and analytical modules transforms telemetry data flows into management decisions, increasing operational sustainability and cost-effectiveness.

Abstract:
Fossil elasmobranch teeth collected from multiple geographic regions, contrasting depositional settings, and different palaeo-oceans/palaeoclimates offer valuable archives of past marine conditions, but they pose a general analytical challenge for us: ensuring comparability among samples affected by locality-specific diagenesis. Primary biological and environmental signatures in enameloid and dentine can be partially overprinted by recrystallisation, mineral replacement, and post-burial elemental uptake. To discriminate these signals reliably, an integrated microstructural–geochemical workflow is required in which scanning electron microscopy is combined with electron-probe microanalysis with energy-dispersive (EDS) and wavelength-dispersive (WDS) X-ray spectroscopy. Deposits formed in different basins, palaeo-continents and palaeo-oceans commonly experienced contrasting diagenetic histories (chemistry, burial temperature, sedimentation time and substitution, redox state of the environment). These factors can overprint tooth tissues in ways that mimic or obscure primary biological/environmental signals. SEM provides the necessary taphonomic and microstructural context prior to geochemical interpretation. Backscattered-electron imaging and high-resolution secondary-electron imaging allow direct assessment of sample preservation states. SEM also resolves diagnostic enameloid ultrastructure, enabling the distinction between preserved biogenic fabrics and diagenetic mosaics that may mimic original biogenic features.

Abstract:
In this brief introductory review, we provide a basic understanding level/basic principles of the biogeography, geoecology/hydroecology, and geochemical role of the plastisphere and the species diversity of microorganisms in the plastisphere. The final section of the article presents a number of experimental approaches and photographs of the instruments used to study it. The technical part of this review is based on the groundwork of a 2018 workshop on microplastic analysis methods, prepared for demonstration at the Institute of Physical Chemistry/ Physicochemical Institute in Moscow (however, without using outdated references). Unfortunately, this work could not be implemented due to the closure of the Moscow base of this institute. However, the general philosophy of this research not only remains relevant today (given the increasing technical capabilities of modern science) but is also becoming increasingly relevant as microplastic pollution of the biosphere increases and the microbiota evolves in the face of climate change. In shortened and terminologically simplified version, this elementary review may be useful to readers, starting with junior students.

Geoinformation Technologies as a Tool for Managing Natural and Economic Systems in the Cryolithozone: from the First Maps to Digital Doubles

European Geographical Studies. 2025. 12(1): 57-61.
Abstract:
The development of the Russian cryolithozone, which occupies 65 % of the country's territory, has historically been a daunting task. Against the background of rapid climate change and intensive economic development of the Arctic, the traditional risks associated with the melting of permafrost have become systemic and widespread. This article argues that it is modern geographic information systems (GIS) that are becoming the central technological solution for a paradigm shift from disaster management to proactive strategic management. The author examines in detail the evolution of GIS: from basic mapping to the development of complex “digital twins” of the territory. These dynamic models, integrating monitoring, survey, and climate forecast data, make it possible to simulate permafrost degradation processes in high detail, assess risks to critical infrastructure, and justify optimal spatial development solutions. The key conclusion of the article emphasizes that in order to ensure the long-term sustainability of vulnerable northern regions, deep integration of GIS platforms with artificial intelligence technologies is necessary, which will open up opportunities for predictive analytics and adaptive planning.

Time-Resolved Scanning Electron Microscopy for Sand Saltation Measurements

6. European Geographical Studies. 2025. 12(1): 62-67.
Abstract:
The role of electrostatics in providing sand saltations is well known (including during the formation of dunes, as well as variations of sand flows in dust storms and sand clouds in aeolology). We propose to use time-resolved scanning electron microscopy for this purpose, since in the column of an electron microscope it is possible to program the potential difference/field strength by varying the accelerating voltage. Examples of time-resolved microimages for calibrated “sand models” are shown in this short paper.
