Authors: Graham Kenny M. , Christophersen Annemarie , Rhoades David A. , Gerstenberger Matthew C. , Jacobs Katrina M. , Huso Rand , Canessa Silvia , Zweck Chris
Published: July 2024

Earthquake forecasts estimate the likelihood of seismic activity within a specific region over a given timeframe, utilizing historical data and patterns from past earthquakes. In New Zealand, the GeoNet program within GNS Science is the main source of geological hazard information and has publicly provided earthquake forecasts since the Darfield earthquake in September 2010. The generation and provision of initial forecasts and subsequent updates have relied on extensive time commitments of experts. The growing use and the desire to make forecast delivery less dependent on personnel capacity have motivated the development of a robust software solution through a hybrid forecast tool (HFT). The HFT is composed of forecast models that cover several different timescales: short term (ranging from a few hours to several years, based on empirical relations for aftershock decay), medium term (spanning years to decades, utilizing the increased seismic activity preceding major earthquakes), and long term (covering decades to centuries, combining information from the spatial distribution of cataloged earthquake locations and slip rates of mapped faults and strain rates estimated from geodetic data). Originally, these models were developed over many years by individual researchers using various programming languages such as Fortran, Java, and R, operating on separate operating systems, with their features documented and published. The HFT unites these models under one umbrella, utilizing a Docker container to navigate disparate software library compatibility issues. Furthermore, the HFT offers user-friendly navigation through a graphical user interface and a command-line feature, facilitating the configuration of automatic and periodic forecast runs. The stability and integration provided by the HFT greatly improve the capability of GNS Science to provide forecasts that inform responses to significant regional seismic events and bring New Zealand closer to automated and operational earthquake forecasting. Although HFT is specifically designed for New Zealand’s earthquake forecasting, the framework, implementation, and containerization approach could also benefit forecasting efforts in other regions.
A Comparative Study of Building Damage in Ston, Croatia, Caused by the Earthquakes of 1850 and 1996
Authors: Herak Marijan , Herak Davorka
Published: July 2024

The small medieval city of Ston in southern Dalmatia (Croatia) has been hit by several strong earthquakes since mid-nineteenth century. The two most important are the ones from the years of 1850 and 1996. Although various aspects of the 1996 event have been well studied so far, the earthquake of 1850 has only recently been macroseismically analyzed. It turned out that the macroseismic epicenters, focal depths, and the epicentral intensities of the two events are virtually the same. As the categories of damage to buildings in Ston caused by the 1996 event were available from previous studies, we here combine details on damage and property ownership from reports in 1850 with the cadastral records from 1837. This allowed us to geolocate most of the damaged houses and thus directly compare the spatial distribution of damage from the two earthquakes. Although the building identification was not straight-forward and unambiguous due to unknown history of each building during the 13 yr between the cadastral survey and the earthquake, the overall damage distributions of both events are found to be similar. They both show the largest damage confined to the plain terrain below the Bartolomija hill characterized by a sedimentary cover 10–30 m thick and expected ground-motion amplification by factors of 3–5. Minimal damage for both events is observed on the hillslopes of Bartolomija in the northern part of the city, where the bedrock is shallow or outcropping. To our knowledge, this observation of the shaking effects for two strong similar earthquakes in a city that has changed little in the 146 yr between them is the only one of its kind in Croatia. It confirms consistency of spatial distribution of earthquake ground-motion amplification for comparable input earthquake motion.

Cluster-network mechanism in ensuring innovative regional development
Authors: Milyukov Aleksey A. , Goman Kirill I.
Published: July 2024

The article discusses the theoretical and methodological foundations of clustering, which serve as the basis for a modern proactive innovation policy. The cluster-network mechanism, which is the most important tool for ensuring the innovative development of regions, is considered. The principle of regional cluster policy is singled out, aimed at progressive development by encouraging the formation of clusters in order to create a self-sustaining ecosystem that ensures economic growth and social well-being in the region. It is stated that the formation of a cluster economy is based on a set of interrelated theoretical, methodological and methodologically sound provisions revolving around the concept of a balance of economic and social interests in order to harmonize relations between regions. Strategies that can be used in the implementation of cluster policy are identified: increasing the critical mass; supporting innovation through funding, grants or other forms of financial assistance; encouragement of cooperation between cluster entities, which involves the creation of networks or platforms that facilitate the exchange of knowledge, or the holding of events and initiatives that bring together stakeholders; development of infrastructure that supports business in a particular industry or sector; creating an enabling policy environment that promotes the growth and development of clusters through a regulatory framework that supports innovation and entrepreneurship. The article substantiates the methodological groups of provisions for the creation of a cluster economy, formulated both positive (presence of modern technological and scientific infrastructure on the territory, readiness of all parties to cooperate, an effective system of interaction between various organizations), and constraining conditions (bad business climate, underdevelopment of associative structures, inadequate planning of the regional economy, neglecting the specific requirements of cluster development), necessary for the functioning of clusters. The definition of the cluster-network approach and its mechanism is also presented, as well as the various stages of the implementation of the cluster-network management model. The integral approach allows us to assess the diversity of the state of the economic system of the region with a high level of clustering. Reflected integral approach allows us to assess the diversity of the state of the economic system of the region with a high level of clustering. In addition, the article proposes a methodological approach to stimulating the cluster-network mechanism of regional development.

Authors: Tsibareva Marina E.
Published: July 2024

The rapidly developing information technology industry, in the conditions of withdrawal from the Russian market of well-known IT brands such as Intel, IBM, Avast and others, faced the problem of a shortage of qualified specialists, investments, equipment and software. In conditions of limited resources, IT companies must offer domestic organizations new software that can fully replace foreign analogues. As part of import substitution, ensuring technological independence and security of Russia's critical information infrastructure (CII), regulatory legal acts were signed, according to which organizations, including state and departmental ones, are obliged to switch to using Russian software (software), including at CII facilities. To solve this problem, it is necessary to provide the IT industry with qualified specialists, the need for whom is growing not only quantitatively, but also professionally. The personnel shortage in the IT sector undermines the economic security of companies and can bring to naught all the efforts of the leadership to resist foreign information technologies. This circumstance determined the topic of the study – to assess the personnel component of the economic security of IT companies in Russia in order to identify problems and ways of developing the IT industry. The components of the personnel component of economic security (hereinafter referred to as personnel security) are defined: intellectual (number of trained); personnel efficiency; dynamics and movement of personnel; physical safety; staff motivation. The most vulnerable components were: labor efficiency; physical safety. The analysis of these components made it possible to identify areas for ensuring personnel security, including: increasing the responsibility of employees for disclosing information; informing employees about cyber defense measures; training (including trainings) of employees to improve their skills; early education and training of young people for the implementation of creative and innovative initiatives in the IT field.

Authors: Mikhaylenko Leonid V. , Shchelokov Dmitry A.
Published: July 2024

An analytical and digital model of the effect formation has been developed, taking into account the reliability level of launch vehicles, which allows us to study the impact of changes in the level of qualification of employees on the value of reliability, price, unit cost, salary, differs from existing ones in that in the presented model the controlled parameter is a change in the qualification of personnel. The problem of choosing enterprise strategies based on the reliability of launch vehicles and the level of qualification of personnel using the profit maximization criterion to evaluate the company's activities is considered. In the presented model, the controlled parameter is the change in the qualification level of personnel from the condition of maximizing the profit received by the enterprise. The paper defines the functional dependences of the reliability of launch vehicles and the amount of wages, prices and unit costs on the level of qualification of personnel. The paper defines the functional dependences of the reliability of launch vehicles and the amount of wages, prices and unit costs on the level of qualification of personnel. With a known optimal level of personnel qualification, the optimal value of the reliability level of launch vehicles has been determined. The effectiveness of investments in improving the qualification level of personnel for the control and management of the quality of manufacturing launch vehicles and changes in the cost of manufacturing a launch vehicle has been determined. To assess the effectiveness of investments in improving the qualification level of personnel for the control and management of the quality of manufacturing launch vehicles, the amount of change in employee salaries has been determined. To assess the effectiveness of investments in improving the qualification level of personnel for the control and management of the quality of manufacturing launch vehicles, the value of the cumulative change in profit before taxation was determined, taking into account the increase in profit by reducing the cost of the launch vehicle, increasing the price of launch vehicles and reducing profits by increasing salaries to employees and the amount of investments in improving the level of qualification personnel for the control and management of the quality of production of launch vehicles
Financial and economic prerequisites for the reorganization of the production system of the machine-building complex
Authors: Slavyanov Andrey S.
Published: July 2024

The production system of the domestic economy, built on the basis of long-term contracts with suppliers of labor items and consumers of products, has shown its instability in the conditions of modern instability of the external environment. Restrictions on the supply of software, equipment, and materials have created the threat of a critical gap between products with high added value and the global technical level due to a break in technological chains. This and other threats determine the relevance of this work. In the study, machine-building enterprises were classified based on specialization into three groups, which have specific capabilities for adapting to the external environment. It has been determined that the main prerequisites for a large-scale reorganization of the domestic production system are threats to state sovereignty, the multiply increased need of the national economy for various complex technical facilities and spare parts, and financial and logistical instability. The departure of foreign investors from the Russian market created conditions for expanding the market share of domestic companies and increasing production output. At the same time, the departure from the Russian market of suppliers of equipment, spare parts and tools, as well as companies providing service, gives grounds to assert that in addition to modernizing the main production, the enterprise infrastructure, which includes repair and tool departments, also needs restructuring. The analysis of the sensitivity of enterprises of various specializations to factors influencing product output showed that the most resistant to external influences were enterprises of technological specialization that produce standard products - rolled metal, fasteners, cast and welded workpieces. The main problem here is cost reduction, which is achieved by introducing new technologies. Particularly vulnerable are industries that produce complex technical products - vehicles, machines, equipment and other machines, the models of which are updated over a short period. To solve this problem, it is proposed to reorganize the current production model into flexible production systems based on the use of robotic systems and multifunctional equipment built into production lines.
Analysis of coordinating parameters in optimization models of supply chain coordination
Authors: Gorokhov Dmitry Yu.
Published: July 2024

The problem of optimal control in a supply chain that includes a supplier and a retailer is considered. The supply chain is presented as a model of interaction between agents, and is formally organized in the form of a supply contract. Based on the analysis of various types of contracts used in economic practice, the article obtained the following new scientific results. The concept of supply chain coordination has been formed, which defines the step-by-step process of establishing contractual relations between the supplier and the retailer based on the existence of vertical market connections of these agents through their integration and coordination of their interactions. The fundamental properties of the vertical “supplier-retailer” system are identified, which explain the need for a compromise choice of coordinating contract parameters that affect the utility functions of both the supplier and the retailer. Various types of supply contracts are formalized, the models of which are presented in the form of systems of utility functions of the participants in these relations, on the basis of which a set of coordinating parameters is determined. It is shown that the range of values of the coordinating parameters forms a Pareto set. A classification of contract optimization models with a different number and set of coordinating parameters is presented, on the basis of which a hierarchy of complication of optimization models is formed, corresponding to the degree of approximation of the models to the real processes of economic interactions in the «supplier-retailer» system. This lays the methodological basis for creating a generalized model of supply chain management, which makes it possible to develop methods for optimizing management in such chains on a unified formal basis.

Published: July 2024

Taking into account the decline in demand for oil in the world as a result of the geopolitical situation and the consequences of the COVID-19 crisis and, as a result, the introduction of measures to limit its production, the issue of optimizing the operating costs of the oil complex is even more relevant. The purpose of this study is to develop theoretical and methodological provisions for assessing and improving the efficiency of the production activities of oil producing enterprises. The evolution of the essence and content of the concept of «efficiency» is considered, and the main modern approaches to its assessment are presented. Based on the results of the identified principles for the efficient operation of enterprises, it is proposed to evaluate the efficiency of the production activities of oil producing companies using two approaches: economic efficiency and target efficiency. Thepractical significance of the results of the study lies in the fact that by determining the interdependent indicators of oil fields in the Urals-Volga region on the basis of a simplex method for solving linear programming problems, a methodology has been developed for assessing the level of target efficiency of the production activity of an oil producing enterprise. The authors proposed for implementation organizational and technical measures to increase the level of efficiency of production activities by optimizing the well repair cycle of an oil producing enterprise. The obtained results of the assessment allowed the authors to identify the existing unrealized production potential under the item «Well servicing and workover» in terms of reducing the average workover time and effectively using the approved cost of a unit price. The scientific novelty of the study is determined by the developed methodology for assessing the level of target efficiency of the production activity of an oil producing enterprise. It is concluded that the developed technique can be implemented at any enterprise of the oil-producing complex.
Analysis of trends and perspective parameters of the assessment of import substitution processes of industrial enterprises
Authors: Anisimova Valeria Yu.
Published: July 2024

In the context of reduced imports of foreign-made products and restrictive sanctions, the Russian economy has been forced to pursue an active import substitution policy for ten years. The article considers the principles of analytical research of the best practices and techniques of import substitution, which increase the competitiveness of industrial enterprises. Modern economic trends, characterized by rapidly changing conditions of the organization of the production process in a particular branch of the industrial sphere, are directly related to the introduction of new technologies, the development of equipment and components capable of replacing similar imported goods. Therefore, the problem associated with overcoming the crisis of replacing imported goods, services, components for high-tech equipment and software remains. The assessment of the formation of conditions for Russian manufacturers and companies whose activities are directly or indirectly related to the development of the country's industrial cluster is given. Since the share of imported products, on which the well-being and stability of many industries depend, is still quite high despite the import substitution strategy in the Russian Federation until 2030, this dependence is decreasing at a low, albeit steady pace. In this regard, the industries that require increased attention in this matter are analyzed – reducing import dependence in production, which is possible only in conditions of increasing output of import-substituting products that can meet the needs of a particular industrial sector. This applies primarily to industrial production, the work of which requires the use of high-tech equipment, manufacturing industries, as well as the IT sector. However, key industries will be able to develop further only if they increase the volume of high-quality domestic products instead of imported ones. But Russian manufacturers who are ready to enter the market with such products are not always competitive enough, which in the future often creates difficulties for entering the leading positions in the production of import substitution products and, importantly, their retention. This is a reason to reduce production or release products in limited quantities. Therefore, the article contains provisions on the expediency of organizing import-substituting production in accordance with the needs of industrial enterprises in various fields of activity in import-substituting products. Such analytical aspects will make it possible to quickly and effectively identify the structural elements of production that require the launch of the import substitution process in the first place, if the process is economically justified and its launch is expedient in accordance with the strategy of sustainable development of the enterprise.

Nowadays, brackish water/seawater desalination is a subject of concern to many researchers all over the world. Solar desalination is a renewable energy-driven method that produces freshwater from saline/brackish water. Many coastal countries suffer from a scarcity of freshwater. Solar-driven desalination is an optimistic and sustainable method to reduce the shortage of potable water in remote regions. Solar desalination is a viable way to produce potable water from any type of non-drinkable water. The recourse to use of solar energy in desalination by distillation, represents as appreciable part of water resources and is realizable, simple, cost-effective, operational solution technically. In this work, Modelling and simulation analysis of single-slope solar still for desalination of water is investigated in CFD-Ansys by considering solar radiation data at 12.8852°N, 77.572625°E in Bengaluru, Karnataka, India. The simulation results found that, the solar still yields the distillate at the rate is 2 litres/m2 for 10 litres of saline water that runs for 12 hours a day (from 7:00 am to 6:00 pm). A comparison between various inclination angles were performed. Solar still yields thermal efficiency of 24% at the inclination angle of 38° when compared with the inclination angles of 22°, 28°, 32° and 44°.

Tengka, identity politics, and the Fiqh of civilization: The authority of Madura’s Kiai in the post-truth era
Authors: Taufiq Muhammad , Amalia Syahidah Jihan , Fauzinudin Faiz Muhammad , Erie Hariyanto
Published: July 2024

This paper explores the role of tengka, a distinctive moral ethic of Madurese culture, in addressing the escalating identity politics in the post-truth era. It focuses on how religious leaders, known as Kiai, in Pamekasan, Madura, respond to identity politics by applying the concept of Fiqh of civilization as a framework for analysis. The study uses a socio-legal approach to explore three key aspects of the Kiai's role: the shifting dynamics of identity politics among the Kiai, the integration of tengka into their approach to identity politics, and the potential benefits and obstacles in this integration process. The findings reveal that the identity politics of the Madura’s Kiai authorities have experienced substantial evolution in the post-truth era. Despite various challenges faced by tengka in the context of identity politics, it presents substantial opportunities for internalization as a strategy to tackle these issues. This aligns with the Fiqh of civilization, which formulates the anticipation of identity politics in realizing al-mashālih al-'ammah (public interest) and strengthening religious moderation. The academic contribution of this research lies in the Fiqh of civilization, which is the contextualization of Fiqh al-siyāsah in analyzing identity politics, offering a unique perspective on the interaction between traditional moral and ethical values and the challenges of modern society.

In 2003–2004, a trapping study with multiple-funnel traps was conducted in Florida, Georgia, North Carolina, and Louisiana to evaluate the effects of the bark beetle pheromones ipsenol, ipsdienol, and lanierone on catches of bark beetles and associated species. The results on bark and ambrosia beetles have been reported previously. Herein, we report on the responses of predators in the same study. Ipsenol and/or ipsdienol attracted several species of coleopteran predators: Enoclerus nigripes (Say) (Cleridae); Temnoscheila virescens (F.) (Trogossitidae); Lasconotus species (Zopheridae); Corticeus species (Tenebrionidae); and Platysoma attenuatum LeConte, Platysoma cylindricum (Paykull), and Platysoma parallelum (Say) (Histeridae). Lanierone was not attractive alone, nor did it enhance trap catches of any of these predator species. In Georgia, lanierone interrupted attraction of E. nigripes to traps baited with ipsenol. We highlight that the use of lanierone appears to be restricted to three Ips species in the subgenus Ips (Bonips). Further research on the general role of lanierone in the chemical ecology of bark beetles and predators should be conducted over a broad geographic range.

Utilizing essential oils extracted from specific herbal plants offers an intriguing alternative to synthetic insecticides, which are known for their harmful effects on both consumers and the environment, in preventing the devastation caused by the sawtoothed grain beetle, Oryzaephilus surinamensis L. (Coleoptera: Silvanidae). This study aimed to explore the chemical composition and insecticidal activities of essential oil derived from Syzygium aromaticum (L.) Merrill & L.M. Perry against adults of O. surinamensis. The research involved assessing the chemical compound of the essential oil from the flower buds of S. aromaticum, evaluating its fumigant toxicity and its repellent effect on O. surinamensis adults through vapor-phase testing conducted in laboratory conditions at 30°C ± 5°C and relative humidity of 70% ± 5%. The experimental design used a completely randomized design with four replications and six concentrations (0, 10, 20, 30, 40, and 50 μl/l of air). A total of nine chemical constituents was identified, with eugenol (90.15%) emerging as the primary compound in S. aromaticum essential oil. The fumigation toxicity (50% lethal concentration) assessments on adult O. surinamensis at 24, 48, and 72 h revealed values of 9.70, 6.58, and 4.37 μl/l of air, respectively. Over the 24- to 120-h test period, the application of S. aromaticum essential oil at 50 μl/l of air resulted in the highest adult mortality among O. surinamensis. Notably, at a concentration of 40 μl/l of air, the essential oil of S. aromaticum demonstrated a fumigation efficiency of 90–100% at both 24 and 72 h, showing no significant difference compared with a concentration 50 μl/l of air. These findings highlight the potential of S. aromaticum essential oil as an effective insecticide for controlling O. surinamensis populations in agricultural storage.

Samples having the chemical formula Li0.5 Fe2.5 – x MgxO4 (0 ? x ? 1) were prepared by the standard ceramic method. The parts of the dielectric constant ?', ?'' and A.C. conductivity ?(?) are measured at different frequencies from 10 – 2 to 105 Hz in the room temperature and different cooling velocity, and then the dielectric loss tangent tg ? was calculated. The sample with x = 0.1 what was cooled quickly showed the greatest values of ?0 as compared with the other samples. The effect of Mg2 + concentration on the dielectric parameters is discussed according to the Koops model.

Introduction: Bell’s palsy is a lower motor neuron (LMN) palsy that affects the facial nerve (CN VII) and causes weakness or paralysis of the facial muscles. It can be associated with various causes, including neurovascular cross-compression (NVCC). This case report highlights the challenges in treating recurrent Bell’s palsy caused by NVCC and the need for a multidisciplinary approach.
Case report: A 17-year-old girl presented with recurrent right-side Bell’s palsy along with NVCC involving the right and left anterior inferior cerebellar artery forming a loop around the VII and VIII cranial nerve complex. Motor Nerve Conduction Studies (NCS) indicated a right-side facial nerve lesion with prolonged distal latency.
Discussion: Despite prior physiotherapy sessions, which proved effective, the patient showed no improvement after five sessions, leading to further investigations. This case also underscores the diagnostic and therapeutic complexities associated with NVCC-induced Bell’s palsy, which emphasizes the urgency of quick diagnosis and intervention to prevent functional limitations.
Conclusion: Continued research and advancements in diagnostic and therapeutic modalities are required for better outcomes and improving the quality of life in such patients, particularly in such cases.
