THE FORMATION OF EFFECTIVE MANAGEMENT OF TECHNICAL-GEOLOGICAL SYSTEMS IN GEOLOGICAL SUBSOIL: REALITY AND PERSPECTIVES

A technical-geological system (TGS) consists of geological environment, man-made objects (techno-sphere) and management system, which are divided into a number of individual components. This all can be considered as natural - anthropogenic complex. The effective functioning of such complex set as TGS is provided by perfect theory, management methodology and by the degree of information fullness and its reliability. We study the “mining deposit-geological environment” systems as technical-geological system (TGS) with the following constituents: geological object rated as deposit facility with defined economic assessment, technical equipment for the conduction of extraction works and management system of all processes in TGS. The investigation of mineral deposits as TGS has three practical aspects: 1) it refers to the study of the geological environment as the environment of human living; 2) it is associated with the study of geological bodies as natural resources; 3) it is associated with retrospective research based on the study of dynamical systems, as well as with determination of the forecast of mineral resources exploration. Mastering of mining deposit should be provided with such information capabilities that match the complexity of the TGS, in order to be able to control its condition, relationships, and flows of matter, energy and information. Accordingly, this situation will provide TGS management the capacity to bring economic development in the fields of deposit development to order. The basis of management is the development of the impact of the managing institution on the object of management, which is revealed sin formation process that provides acquisition, processing and analysis of obtained data to build a model of TGS state, using the estimated parameters, develop­ment of recommendations for the implementation of managing in flounce. This approach can be considered as theoretical basis of rational subsoil use. The effective management of the TGS resource potential has to be a flexible system that will change, adapt to market conditions, thus ensuring maximum utilization of mineral resources while preserving the environment. Based on this, the systematic approach to effectively manage resource potential TGS is proposed. The economic evaluation of reserves and mineral resources should be conducted on each stage of the development of the mineral resources complex for the purposes of increasing the validity of decisions and formulation of a comprehensive development strategy based on the standards of international level of the system CRIRSCO (Committee for Mineral Reserves International Reporting Standards). CRIRSCO implementation is held starting with the assessment of the efficiency of the industry as a whole and should serve as a basis for the selection of priority directions of its development at all stages of geological prospecting and operation of mineral resources

TRIBUTE TO THE LIFE OF ACADEMICIAN NAN OF UKRAINE, EVGENIY SHNYUKOV

This article is devoted to the life and activities of Doctor of Geological and Mineralogical Sciences, Academition NAN of Ukraine Evgeniy Shnyukov. Professor Shnyukov was a world-famous Soviet and Ukrainian scientist, founder of the discipline of marine geology in Ukraine, and Academician of the National Academy of Sciences of Ukraine. He was born on March 26, 1930 in the city of Arkhangelsk, located at the mouth of the Northern Dvina River, and he passed away on November 1, 2022 in Kyiv at the age of 93. He was a member of the National Academy of Sciences of Ukraine, and a highly honored researcher, having been twice a laureate of the State Prize of Ukraine in the field of science and technology. His scientific interests were extremely wide and were covered by more than 700 publications. He was the first among geologists to come to the conclusion that, as a maritime state, Ukraine was obligated to develop marine geological research. Akademician Shnyukov promoted the exploration of marine geology at Odessa I. I. Mechnikov State University, constantly and fruitfully working with scientists of the Department of General and Marine Geology as its chief scientific consultant. With great respect, he spoke about our successes and treated the staff of the department and students with great warmth. His integral feature was that he treated great scientists and young employees with equal respect. He loved Odessa very much, called it his “Little Motherland,” and often visited to conduct joint expeditions in the Black Sea and along its coast as part of joint domestic and international scientific projects. He also organized international scientific conferences. In 1992, by decision of the Presidium of the National Academy of Sciences of Ukraine, the Department of Marine Geology and Sedimentary Ore Formation of the National Academy of Sciences of Ukraine was established, with E. F. Shnyukov appointed as its head. Until his last breath, Shnyukov worked tirelessly to confirm the status of Ukraine as a maritime state and to provide it, through research, with energy resources and raw materials. The scientific achievements of Akademician Shnyukov include his founding of a new direction in the field of sedimentary ore formation – the metallogeny of mud volcanism – with which he contributed to the expansion of the mineral and raw material base of Ukraine. In fact, he is the “father” of marine metallogeny. An outstanding and talented scientist, a person full of vital optimism, a sense of humor, benevolence, sensitivity, and an outstanding personality – Evgeniy Shnyukov will forever remain in the hearts of his friends and colleagues, as well as everyone who knew him, communicated and worked with him, respected him, and loved him.</jats:p

LITHOLOGY AND HYDRODYNAMICS OF THE BLACK SEA ODESSA COAST UNDERWATER PART

Problem Statement and Purpose. The results of lithological studies, including granulometric analysis, are needed to identify the conditions of sedimentation and distribution of rock fragments by size. They are an indicator of the sedimentation processes dynamic structure peculiarities. The study of the sediment regime is important for the development of measures related to the protection of shores from erosion. The aim of the work is to identify the lithological features of the bottom sediment types distribution on the protected section of the Odessa coast near Cape Maly Fontan. Data &amp; Methods. The materials for this work were obtained in the field research in the summer 2019 in the coastal zone between the hydrobiological station of Odessa I. I. Mechnikov National University, and Cape Malyj Fountain. Three measuring profiles were made perpendicular to the shoreline at 1200 m towards the sea to a depth of 18 m. 35 samples were taken from the upper layer of bottom sediments. Field samples processing was performed in the Problem Research Laboratory of Engineering Geology of the Sea Coast, Reservoirs and Mountain Slopes of Odessa I. I. Mechnikov National University. Granulometric classification was performed. Excel, Statistica, Golden Software Surfer programs were used to process the results. Results. Underwater relief analysis showed that the coastal part is an abrasive terrace, on which ancient landslides relics are widespread. There are 7 main lithological types of bottom sediments detected. The largest areas covered by fine-grained loamy sands and shell detritus with gravel, pebbles and sand. Analysis of distribution curves and cumulative curves of granulometric distribution showed that coarse sediments are characterized by multi-vertex distribution curves and stepwise stretched cumulative curves, which indicates the heterogeneity of sediments in granulometric distribution. For fine-grained material, which is well sorted, the distribution curves are almost single-vertex, and the cumulative curves have a large steepness and a simple, non-stepped shape. There are three hydrodynamic detected in bottom sediments lithology according on statistical parameters of grain size. Outer marine part with depth more than 15 meters characterized by low hydrodynamic processes and presented by good-sorted sands and silt. The central part of polygon in 4–15 meters depth covered by shell detritus with gravel and pebble of carbonate rocks and connected with rocky extrusions after coastal landslides. The feature of this part is active hydrodynamic processes. The rocky extrusions presented like natural breakwater and due to waves braking and collection of different types of sediments. The coastal part in 2–4 m depth in front of constructed breakwater leads to decreasing of wave energy and sedimentation of good-sorted sands.</jats:p

EXPERIENCE IN APPLYING EXPERT ANALYSIS AND RANK CORRELATION DURING GEOLOGICAL AND FORECASTING WORK ON HYDROCARBONS

Problem Statement and Purpose. The diverse and extensive geological materials and geophysical data used in forecasting and prospecting operations for oil and gas exploration within the Black Sea’s northwestern shelf are usually interpreted in a complex manner. This complexity, however, is often spontaneous and fragmentary, with no new theoretical concepts taken into account. For example, the theory of global fluidogenesis represents an alternative hypothesis to the organogenic-sedimentary formation of hydrocarbon deposits but is commonly not considered. The authors of this article believe that the complexity should be replaced by a method of directed rank interpretation of geological information, in which ranking distinguishes the maximum information on one of the sections of geological work with regard to its completeness and consistency. The purpose of this study is to apply expert analysis and rank correlation of obtained information to geological and forecasting research on hydrocarbons. To achieve this goal, two basic principles, rank and direction, are considered. The data include seismic, tectonic-geodynamic, lithological, geochemical, mineralogical, and meiobenthic characteristics of the sea bottom scaled according to their sensitivity to the independent variable, i. e., hydrocarbons. Study area, material, and methods. The Pradneprovskaya area has been chosen for analysis. It is a promising location for oil and gas exploration in the shallow part of the inner northwestern shelf of the Black Sea. Geologically, this is the area of junction for the South Ukrainian monocline with the system of blocks included in the Predobrudzha-Crimean riftogenic trough. The area was studied by geophysical, geochemical (hydrocarbon gases, liquid hydrocarbons), mineralogical (X‑ray diffraction of clay minerals, thermobarogeochemistry of inclusions in minerals), and paleontological (foraminifera, nematodes, ostracods) methods, along with the drilling of a deep (2352 m) parametric well (Pradneprovskaya‑2). Results. It is shown that expert analysis of the diverse information within the framework of selected tasks, which are poorly formalized into a single system, provides the basis for an effective method of comparing information databases formed on different principles. This analysis is founded on the principle of directed (vector) ranking, where each rank narrows the search area and becomes more sensitive to the hydrocarbon deposit. The article gives an example of how this method can be used for a specific objective in its entirety, namely: (a) selection of information ranks (parameters), (b) selection of experts, (c) calculation of the rank matrix, (d) determination of hierarchical dependencies of ranks, (e) verification of the matrix, and (e) calculation of the concordance coefficient. The obtained results indicate that the proposed method of expert analysis with rank correlation under modern conditions using diverse geological materials that are not formalized into a single database, provides high reliability in the comprehensive interpretation of data. The method will help optimize geological and forecasting research on hydrocarbons within the Black Sea shelf.</jats:p

Label-free measuring and mapping of binding kinetics of membrane proteins in single living cells

Membrane proteins (MPs) mediate a variety of cellular responses to extracellular signals. While MPs are intensely studied for their values as disease biomarkers and therapeutic targets, in situ investigation of binding kinetics of MPs with their ligands has been a challenge. Traditional approaches isolate MPs and then study them ex situ, which does not accurately reflect their native structures and functions. We present here a label-free plasmonic microscopy method to map the local binding kinetics of MPs in their native environment. This new analytical method can perform simultaneous plasmonic and fluorescence imaging, thus making it possible to combine the strengths of both label-based and label-free techniques in one system. Using this method, we have determined the distribution of MPs on the surface of single cells, and the local binding kinetic constants of different MPs. Furthermore, we have studied the polarization of the MPs on the cell surface during chemotaxis
