Effect of water Resource utilization in Poyang lake area on carbon emissions based on decoupling theory

The utilization of regional water resources has the potential to impact carbon emissions. Maintaining a decoupled relationship between water resources and carbon emissions facilitates harmonious regional development. Understanding the mechanism of their coordination is conducive to achieving the "Double Carbon" goal and control of regional carbon emissions and water resource consumption. This study examines the decoupling relationship between water resource utilization and carbon emissions in Poyang Lake area, China, employing the Tapio decoupling model and the LMDI(logarithmic mean divisia index) decomposition model. The results indicate that carbon emissions in Poyang Lake area exhibited a gradual increase, accompanied by an annual growth rate of 5.99 %. The water supply exhibited a slow expansion. They have exhibited state of affairs strong negative decoupling and expansive negative decoupling over the past 15 years. Moreover, this situation is most acute and worsening in the secondary industry. The water use structure effect and water economic benefit effect are the primary factors affecting carbon emission increases, contributing 57.93 % and 65.66 %, respectively. Carbon emissions intensity is the largest inhibiting factor, which accounts for a maximum contribution of 42.96 %. The order of potency of the driving factors is as follows: water economic benefit > carbon emission intensity > water use structure > water use efficiency. In summary, this research recognised the enhancement of the water economic efficiency index not only facilitates the decoupling phenomenon but also improves the water-carbon relationship, especially in the secondary industry. It serves as a compelling illustration of the significance of elucidating the interrelationship between regional water and carbon dynamics, and charting the course for the formulation of regional policies that would facilitate the advancement of environmentally conscious and carbon-neutral development, as well as water conservation.

Investigations of Silica/MOF composite coating and its dehumidification performance on a desiccant-coated heat exchanger

Desiccant materials have an important impact on the dehumidification performance of desiccant-coated heat exchanger (DCHE). In this paper, a desiccant-coated heat exchanger based on a composite desiccant material of metal organic frameworks (MOFs) and silica gel was proposed. The coating was experimentally prepared and tested for its hygroscopic performance under different binder types (PVP, PVA, and PVB), different binder mass concentrations, and different MOF mass concentrations in the composite adsorbent. Further simulations were performed to investigate the effects of key structural and operational parameters on the performance of DCHE. Experimentally, the optimal hygroscopic performance of the composite adsorbent was obtained at 15 wt% PVP and 20 wt% MOF, which was 51.71 % higher than that of silica coating, and the cost of the composite adsorbent drops 78.04 % by comparing to the pure MOF for laboratory fabrication, and based on the novel economic efficiency index proposed in this paper, the mass concentration of the MOF should not exceed 32.8 wt%. Simulation results showed that under the conditions as follows: 1.2 mm (fin spacing), 25 mm (fin height), 0.28 mm (coating thickness), 25 °C (cooling water temperature), and 0 % (initial moisture content), the corresponding moisture removal capacity (MRC) and of DCHE was 6.740 g/kg, which was 149.63 % higher than that of silica coating.

The Trend in Environmental Load in the European Union during the Period of 2012–2022

The environmental burden is a global problem affecting the European Union. A comprehensive analysis of the environmental burden is essential for creating strategies supporting sustainable economic development. This study attempts to answer the question of why, despite the continuously decreasing energy consumption of the EU, the environmental burden of this region is not substantially decreasing. This study provides novel insights into this research area by integrating EU economic dynamics and environmental efficiency indicators. In this study, we used the IPAT method. Before the main analysis, the researcher conducted cross-sectional dependence, slope heterogeneity, and Westerlund cointegration tests using the primary data. Based on the results, the EU member states were classified into clusters, and a linear trend model analysis was carried out. The results show that the total environmental load of the EU did not decrease significantly between 2012 and 2022. The fact that the environmental burden remained at the same level is explained by the fact that there were 16 member countries whose total environmental load increased but whose economic output was lower during this time period. This was offset by 11 member countries with high economic outputs, whose total environmental load decreased. This study proved that GDP growth was the main driving force maintaining the total environmental load at the same level. The EU should encourage member states to continue to implement environmental protection rules to limit and eliminate costly environmental burdens on their societies and economies. This study can be helpful to researchers, political decision-makers, and experts working on environmental public policies for the EU.

Economic efficiency of small-scale wheat production in Jigawa state, Nigeria

Africa’s most populous country has failed to grow more food for its fast-rising population. With 420,000 metric tons of wheat produced in Nigeria in 2020, the country is still far from bridging its 4.6 million metric tons annual wheat gap. Increasing wheat production is a challenge for the nation to fulfill the food requirements of its growing population. So far literature has shown a rise in research on wheat in different parts of Nigeria, with a paucity of information on the economic efficiency of wheat production in the study area, and the country in general. To bridge these knowledge and empirical gaps, this research investigates the economic efficiency of wheat production in Jigawa State of Nigeria using information gathered from a survey elicited by a well-structured questionnaire coupled with an interview schedule from 341 active wheat farmers selected through a multi-stage sampling technique. Both descriptive and inferential statistics were used to analyze the data collected. Empirically, despite the wheat enterprise being profitable in the study area, farmers didn’t achieve the targeted goals of output maximization, cost minimization, and profit maximization as evident respectively by the technical, cost, and economic efficiency indexes. However, these goals were challenged by induced human risks viz. gender discrimination that affects women’s access to productive resources, poor labor productivity due to diminishing marginal returns associated with old age, capital consumption triggered by increased income, poor prioritization of wheat enterprise as a business, and vulnerable household size. Furthermore, the identified constraints mediating the links that affected the economic efficiency of wheat farmers were price/marketing, technological, managerial, and infrastructural risks. Therefore, for long-run sustainable wheat production, the responsibility lies on policymakers to concentrate more on marketing and technological risks challenging wheat production in the study area as empirically established by this research.

Economic efficiency and finance in the development of the forest economy within the framework of legal restrictions

The present study aims to analyse the factors that determine the economic efficiency and optimal models of forestry financing in the context of the current legal framework. The article discusses the critical importance of forestry for global environmental sustainability and economic development. It is determined that economic efficiency in this area is to achieve the maximum economic result while minimizing costs and making optimal use of resources. The main indicators of economic efficiency are the productivity of forest resources, which depends on the ability to maintain and restore forest plantations, as well as on cost optimization, including operating costs and investments in modern technologies. Economic efficiency is also determined by financial results, including revenues from the sale of forest products and profitability of enterprises. An important aspect was the consideration of environmental and social aspects, such as the impact of forestry on ecosystems and employment. The article emphasized the role of innovative technologies, such as geographic information systems and remote sensing, in improving the efficiency of forest management. The article analyses the impact of access to financial resources, level of technological development, management approaches, legislative framework, environmental sustainability and market conditions on the economic efficiency of forestry in Kosovo. As a result, recommendations were made to improve the economic efficiency of forestry, including increasing financial support, attracting international investment, improving the legal framework and developing international cooperation. Implementation of these measures will contribute to the conservation and efficient use of forest resources, ensuring economic stability and environmental safety of the country

Carbon efficiency evaluation method for urban energy system with multiple energy complementary

Urban energy systems (UESs) play a pivotal role in the consumption of clean energy and the promotion of energy cascade utilization. In the context of the construction and operation strategy of UESs with multiple complementary energy resources, a comprehensive assessment of the energy efficiency is of paramount importance. First, a multi-dimensional evaluation system with four primary indexes of energy utilization, environmental protection, system operation, and economic efficiency and 21 secondary indexes is constructed to comprehensively portray the UES. Considering that the evaluation system may contain a large number of indexes and that there is overlapping information among them, an energy efficiency evaluation method based on data processing, dimensionality reduction, integration of combined weights, and gray correlation analysis is proposed. This method can effectively reduce the number of calculations and improve the accuracy of energy efficiency assessments. Third, a demonstration project for a UES in China is presented. The energy efficiency of each scenario is assessed using six operational scenarios. The results show that Scenario 5, in which parks operate independently and investors build shared energy-storage equipment, has the best results and is best suited for green and low-carbon development. The results of the comparative assessment methods show that the proposed method provides a good energy efficiency assessment. This study provides a reference for the optimal planning, construction, and operation of UESs with multiple energy sources.

Assessment of Innovative Development of Regions in the Context of Structural Transformation of the Economy

Today, the development of economic systems is taking place in an era of transformations that lead to the formation of new economic models. Russia is no exception here. The main impetus for the transformation processes in our country’s economy was the anti-Russian sanctions directly related to political events from the United States, Canada, European and other countries. All this poses threats to Russia’s political, economic and social security. Therefore, in modern realities caused by sanctions pressure, the key strategic task of overcoming crisis phenomena and shocks is the formation of a new industrialization based on domestic innovations. It is important to assess the innovative potential of the regions in order to further develop management decisions. The authors proposed and tested a methodological approach to assessing the level of innovative development of the subjects of the Russian Federation. The algorithm of this approach includes sampling official statistical data, determining localization coefficients, averaging and evaluating their dynamics. It was determined that in the period 2011-2022, less than a third of Russian regions improved their economic efficiency and innovation localization indicators. The leading regions of innovative development have a high level of localization of the studied characteristics. Regions characterized by low localization coefficients are traditionally lagging behind and have low indicators of economic, including innovative development. The problems of innovative development of regions under the influence of transformational processes are very multidimensional, therefore, in the limited space of this article, only an assessment of innovative development based on the author’s methodological approach is given.

Grain yield and interspecific competition in an oat-common vetch intercropping system at varying sowing density.

Oat (Avena nuda L.) and common vetch (Vicia sativa L.) intercropping in the northern regions of China has resulted in substantial production capabilities. However, there is currently a dearth of comprehensive research on whether this intercropping system can enhance productivity through increased sowing densities and underlying interspecies interaction mechanisms. A two-year field experiment was conducted in 2022 and 2023 to investigate the yield, biological efficiency, economic efficiency, and competition indicators of oats and common vetch in a high-density intercropping system. Two cropping patterns (monocropping and intercropping) and five sowing densities (D1: 4.5×106 plants ha-1; D2:5.4×106 plants ha-1; D3:6.3×106 plants ha-1; D4: 7.2×106 plants ha-1; and D5: 8.1×106 plants ha-1) were arranged in a randomized block design. At the same sowing density, the intercropped oats exhibited greater grain yield than the monocultures. Increasing the oat sowing density significantly enhanced oat yield, with the D3 level in intercropping showing the highest yield increase, ranging from 30.98% to 31.85%, compared with the monoculture. The common vetch intercropping grain yield was maximized in the D2 treatment. The land equivalent ratio was maximized at the D2 level in both years and was significantly higher than D1, with the land equivalent coefficient, system productivity index, and percentage yield difference suggesting that increasing oat sowing densities improved the productivity of the intercropping system, with the best performance observed at the D2 level. For both years, the proportionate actual yield loss of oat was the highest at the D3 level; significantly surpassing D1, proportionate actual yield loss of common vetch and actual yield loss were the highest at level D2, both significantly surpassing D1. These indicates that appropriate densification contributes to the realization of the advantages of intercropping. With an increased oat sowing density, the economic benefits of the intercropping system were maximized at the D2 and D3 levels. Regarding intercropping competition, oat was the dominant crop under different sowing densities (Aggressivity for oat (AO)>0, relative crowding coefficient for oat (KO)>1, competition ratio for oat (CRO)>1), whereas common vetch was the inferior crop. Compared with the D1 level, the D2 level harmonized the aggressivity, competitive ratio, and relative crowding coefficients of oat and common vetch, significantly increasing crowding coefficient for common vetch (KV) and competition ratio for common vetch by 19.76% to 21.94% and 4.80% to 7.51%, respectively, while reducing KO and CRO. This result suggests that in the intercropping of common vetch and oat in alpine regions, rational densification can harmonize interspecific competition and thus improve the biological efficiency and economic benefits of intercropping systems.

The purpose of the study is to improve the recipe and technology for the production of fish cutlets using amaranth bran. Objectives: development of technology and recipe for fish cutlets using amaranth bran; conducting an examination of the quality of the finished dish with calculation of its nutritional and energy value; determination of economic efficiency. The objects of the study were samples of fish cutlets with partial replacement of wheat bread with amaranth bran, as well as a control sample of fish cutlets made according to a traditional recipe. The introduction of amaranth bran was carried out in the following proportions, % of the weight of wheat bread: 1st version of the experiment – 50; 2nd version of experience – 75; 3rd experience option – 100. Replacing 75 % of wheat bread in fish cutlets with amaranth bran helps maintain the juicy consistency of the product, giving a light, pleasant taste and smell. The option with replacing 75 % of the bread with bran showed an increase in the content of proteins, fats, carbohydrates, dietary fiber, and minerals, which demonstrates its readiness for use in catering establishments as a replacement for the control. The nutritional and energy value of this option was calculated. The amount of protein increased by 2.22 %; fat – by 0.44; carbohydrates – by 6.58 %. The amount of minerals increased: K – by 18.02 mg; Ca – by 18.21; Mg – by 28.81; P – by 63.24; Fe – by 0.87 mg. And the content of dietary fiber is higher than the control variant – by 0.93 g. The energy value per 100 g of the experimental sample is 28 kcal higher than the control one. Based on calculations, it was found that the cost of raw materials increased, which led to an increase in the cost of the product. The price of fish cutlets with the addition of amaranth bran was increased, which increased the profit from the sale of one product by 2.05 rubles. The profitability of manufacturing new items increased by 2.8 %, which is considered an indicator of economic efficiency.

DEVELOPMENT OF A VORTEX CHAMBER MODEL TO ESTIMATE THE VALUES OF THE LIQUID AND GASEOUS PHASES

When preparing well products from gas fields at complex gas treatment plants, dry stripped gas and unstable condensate are separated. During the exploitation of a field, development indicators (flow rate, reservoir pressure, composition of extracted products, etc.) change. At the same time, the efficiency of the apparatus for separating the gas and liquid phases decreases, which is accompanied by an increase in the entrainment of the liquid phase from the gaseous phase and can reach about 30–40 % of the total volume. This affects economic efficiency indicators, since the volume of unstable condensate decreases, and, consequently, the profit from its sale.The article is devoted to studying the effectiveness of using vortex chambers to reduce the entrainment of the liquid phase from the gaseous phase during the preparation of well products. The results of the research analysis are presented, methods for assessing phase transitions in vortex chambers and the mathematical models used are described.The work defines the basic equations that describe the process of entrainment of the liquid phase from the gaseous phase. Thus, to describe the phase boundaries, the volume of fluid model is used, and the standard k – ε is used as a flow turbulence model. A model of a vortex chamber is being developed in ANSYS FLUENT, the mesh model is built using elements – tetrahedrons. The size of the mesh elements was determined from the condition of stability of the resulting solution and amounted to 10 mm.The influence of chamber geometry, liquid mass velocity and other parameters on the process of phase entrainment is considered.A comparison of the results of experimental studies and modeling results shows the possibility of reducing the entrainment of the liquid phase as a result of the use of vortex chambers and justify the selected parameters for developing the model.

SUBSTANTIATING THE INFLUENCE OF THE RESULTS OF A COMPETENT ORGANIZATION’S FUNCTIONING ON THE EFFICIENCY OF THE NATIONAL ECONOMY

European integration processes have changed the requirements for organizations, shifting attention from external factors to internal properties. Unique knowledge and experience, combined with resources and technologies, shape the organization's competence, determining its ability to operate effectively. The increasing number of organizations capable of achieving high-performance indicators, i.e. competent in conditions of market activities coloured by military actions, is considered a factor in the development of the national economy. This work aims to justify the predominant impact of the results of Ukrainian organizations' activities, as an indicator of competence, on GDP volumes as a comprehensive indicator of economic efficiency and state development. Methods such as information systematization, grouping and comparative analysis, correlation regression, content and logical analysis, scientific induction, and deduction have been used.An obvious imbalance of the regional structure of the economy with the concentration of organizations in six leading regions (49,85%) was revealed, which does not always indicate their greatest impact on GDP volumes. This confirmed the inexpediency of considering the indicator of the number of organizations as a determining factor of influence on the national economy. The assumption of greater significance in ensuring the stable functioning of the economy based on the results of organizational activities has led to the analysis of the volumes of products produced and sold, their ratios, and projections of trends on GDP volumes. The higher performance of representatives of large and medium-sized businesses is explained by the presence of a wider list of competencies, therefore, higher competitiveness of organizations and the probability of resistance to external changes. Identity, but the unequal trends in production volumes and GDP outline prospects for further analysis of financial performance indicators in the context of their impact on the competence level of organizations, which most fully characterizes their ability to conduct successful activities, ensuring sustainable economic development.
