A New Concept of Techno-Economic Institutions within Institutional Economics: Integrating Technologies and Institutional Frameworks

This study investigates the concept of techno-economic institutions within institutional economics, focusing on the integration of technologies into economic frameworks to foster development. The primary objective is to introduce and advocate for the novel concept of “techno-economic institutions,” which is essential for embedding technologies into the socio-economic environment. This research employs a comprehensive methodological approach, including theoretical analysis, literature review, comparative studies, and case studies, to develop a new analytical model and provide fresh insights. The key findings include a comparative analysis of the interplay between institutions and technologies, a variational model detailing the life cycles of General-Purpose Technologies (GPTs), and an in-depth examination of institutional roles. The econometric models developed in this study demonstrate the significant impact of ICT patents and SCM systems on government efficiency, empirically validating the proposed theoretical framework. This paper contributes to the academic discourse by offering a methodologically robust and empirically substantiated examination of technological advancements in institutional frameworks, highlighting the importance of flexible institutional structures capable of adapting to technological change. These insights provide actionable recommendations for policymakers and suggest strategic investments in technological infrastructure to enhance government performance. Future research should explore the generalizability of these findings in different institutional contexts and examine variability in technology-institution interactions across diverse geopolitical landscapes. Doi: 10.28991/ESJ-2024-08-05-022 Full Text: PD

Study of the effect of baicalin from Scutellaria baicalensis on the gastrointestinal tract normoflora and Helicobacter pylori

The antimicrobial properties of baicalin against H. pylori and several probiotic cultures were evaluated. Baicalin was isolated from a dry plant extract obtained by extraction with water at 70 ◦C. For isolation, extraction was carried out with n-butanol and purification on a chromatographic column. The antimicrobial potential was assessed by evaluating changes in the optical density of the bacterial suspension during cultivation; additionally, the disk diffusion method was used. During the study, the baicalin concentrations (0.25, 0.5, and 1 mg/mL) and the pH of the medium in the range of 1.5–8.0 were tested. The test objects were: suspensions of H. pylori, Lactobacillus casei, L. brevis, Bifidobacterium longum, and B. teenis. It was found that the greater the concentration of the substance in the solution, the greater the delay in the growth of the strain zone. Thus, the highest antimicrobial activity against H. pylori was observed at pH 1.5–2.0 and a baicalin concentration of 1.00 mg/mL. In relation to probiotic strains, a stimulating effect of baicalin (1.00 mg/mL) on the growth of L. casei biomass at pH 1.5–2.0 was observed. The results open up the prospects for the use of baicalin and probiotics for the treatment of diseases caused by H. pylori

Modeling the structure and formation of the oil and gas potential of Riphean-Vendian deposits that belong to north-east regions of the Volga-Ural oil and gas province

The paper is devoted to the urgent problem of studying the prospects of the oil and gas potential of Riphean-Vendian sediments of poorly studied areas such as northeastern regions of the Volga-Ural oil and gas province. The paper presents the characteristic of the lithological and stratigraphic features of the structure of Riphean and Vendian deposits in the northeastern part of the Volga-Ural oil and gas province. Particular attention is paid to the basin modeling of well sections that did not fully passed through the Riphean-Vendian complex of rocks.That allows to predict oil and gas generation processes. During the research sections of three wells were modelled. Wells Keltmenskaya-1, Krasnovisherskaya-18, Borovitskaya-624 revealed Upper Proterozoic rocks in the north-east of the Perm region and the Komi Republic. Procedure features of the used software systems, phasing of the research, including gathering and input of initial data, processing of parameters, calculation and calibration of models are given. Certain challenges associated with modeling the conditions of oil and gas formation and oil and gas accumulation of Riphean and Vendian sediments of this territory are associated with insufficient information on the structure and composition of sediments, incomplete drilling of ancient sediments in wells and inconsistent geophysical data. In addition, the complexity of the reconstruction lies in the lack of information about geothermal conditions of sections, numerous interruptions in sedimentation and erosion of sediments. According to simulation results, most of the Riphean-Vendian sedimentary section is located in the main zone of oil generation. The research conducted allowed the authors to conclude that there are increased prospects to discover oil hydrocarbons in a wide range of depths in the areas where the Krasnovisherskaya-18 and Borovitskaya-624 wells are drilled. There is a little likelihood that gaseous hydrocarbons can be found in the section. Conducted research and obtained results pose a problem for the development of geological exploration in the poorly studied areas of the northeast of the Volga-Ural oil and gas province. First of all, that corresponds to reference-parametric drilling together with the zonal-regional geophysical studies

Volatile Heterobimetallic Complexes from PdIIand CuIIβ-Diketonates: Structure, Magnetic Anisotropy, and Thermal Properties Related to the Chemical Vapor Deposition of Cu-Pd Thin Films

A novel approach for preparing volatile heterometallic complexes for use as precursors for the chemical vapor deposition of various materials is reported. New Cu¢Pd complexes based on b-diketonate units were prepared, and their structures and compositions were determined. [PdL2*CuL2] (1) and [PdL2*Cu(tmhd)2] (2) (L=2-methoxy-2,6,6-trimethylheptane-3,5-dionate; tmhd=2,2,6,6- tetramethylheptane-3,5-dionate) are 1D coordination polymers with alternating metal complexes, which are connected through weak interactions between the Cu atoms and the OCH3 groups from the ligand of the Pd complexes. The volatility and thermal stability were studied using thermogravimetric and differential thermal analyses and mass spectrometry. Compound 1 vaporizes without decomposition into monometallic complexes. It exhibits magnetic anisotropy, which was revealed from the angular variations in the EPR spectrum of a single crystal. The vapor thermolysis process for 1 was investigated using mass spectrometry, allowing the process to be framed within the temperature range of 200–3508C. The experimental data, supported by QTAIM calculations of the allowed intermolecular interactions, suggest that 1 likely exists in the gas phase as bimetallic molecules. Compound 1 proved to be suitable as a single-source precursor for the efficient preparation of Cu¢Pd alloy films with tunable Cu/Pd ratio. A possible mechanism for the film growth is proposed based on the reported data

Tools for assesing sustainable development of territories takinf into account cluster effects

Проблемы и поиски путей устойчивого развития территорий вызывают серьезную обеспокоенность органов власти во всем мире. Выбор методических подходов для оценки и мониторинга, показателей в качестве критериев устойчивости и способов их обработки является важной концептуальной основой, которая помогает эффективно содействовать развитию управляемых территорий. Данное исследование направлено на поиск и анализ существующих подходов и инструментов мониторинга территориального развития, разработку собственной методологической и методической основы оценки устойчивости территорий в целях решения социально-экономических проблем. При этом основной концептуально-методологической предпосылкой, отличающей предлагаемый подход, на наш взгляд, должен стать учет эффектов межрегионального, межотраслевого взаимодействия или, по- другому, эффектов кластерных переливов. Выявлено, что среди авторов по-прежнему отсутствует консенсус не только по теоретическим аспектам, но и по методологическим вопросам процедуры мониторинга и инструментам оценки устойчивости развития, особенно в контексте кластерного подхода. В статье представлен анализ основных методологических подходов к оценке устойчивого развития систем различного уровня (национальной и региональной экономики, территорий, отраслей, предприятий, продуктов). Проведена систематизация подходов и инструментов, используемых учеными разных стран, международными организациями и институтами. Указаны преимущества, недостатки и ограничения практического применения выделенных методологических подходов. Изложена суть метода TOPSIS как инструмента оценки устойчивости развития территорий с учетом мультипликативных эффектов от межрегионального и межотраслевого взаимодействия. Показано, что именно кластерный подход является эффективным инструментом управления устойчивым развитием территориальных систем
