The coupling coordination of digital economy and green high-quality development of industries is an important way for sustainable and high-quality economic development. This paper constructs an evaluation index system for the digital economy and industrial green high-quality development, and conducts empirical analysis using the coupling coordination model, the spatial autocorrelation model, and the Tobit model. The data from provinces and cities in the Yangtze River Economic Belt spanning from 2008 to 2021 has been analyzed. Results show that both subsystems exhibit a good and rising coupling coordination, and the regional coupling coordination demonstrates a trend of higher values in the east and lower in the west. Moreover, there is interaction between provinces and cities, albeit with a weakening correlation after 2011. Additionally, spatial clustering is evident between regions with high and low coupling coordination. The coupling coordination degree of each region is impacted by important factors, such as economic development level, financial level, opening up, fiscal expenditure, and urbanization. Therefore, the study recommends policies aimed at boosting the coupling coordination level in the Yangtze River Economic Belt. Key policy proposals contain promoting the integration and innovation of digital technology and green low-carbon technology, strengthening regional cooperation through the transfer of industries, and adopting differentiated development strategies tailored to regional advantages and the varied impact

Village planning has assigned a single fixed boundary to the village to protect the external spatial form type of the village from destruction. To meet its development needs, the village needs to change the fixed boundary. How to delineate a boundary that does not destroy the external spatial form type of the village but also meets the development needs of the village has become an urgent problem to be solved. This paper proposes a strategy to delineate flexible boundaries for villages. This strategy accomplishes the delineation of flexible boundaries without destroying the spatial form type of the village by adjusting the control parameters to meet the needs of village development for boundaries. Firstly, the strategy calculates the value of the optimal village boundary corresponding to the control parameter, then constructs the mathematical and theoretical relationship between the village’s external spatial form type and the optimal boundary corresponding to the parameter, and finally determines the range of spatial form type corresponding to the control parameter and selects 20 traditional villages in China as empirical evidence. The results show that: the length of control parameters corresponding to the external spatial form types of villages shows the law of segmental distribution; the higher the degree of banding of the external spatial form of villages, the greater the length of control parameters; the range of control parameters for clustered boundary delineation of the village, and the banding tendency of the clustered and banding spatial form types is 15-30, 30-50, and 50-130. The results can provide theoretical references for the planning and design of villages, as well as provide decision-making help for the village participants.

The study underscores the importance of considering the age of rice when evaluating its nutritional and chemical properties for various applications. The first research rice samples, with an age range of 3 to 6 months, were gathered from the Harir subdistrict. The proximate analysis results revealed nine distinct compounds, with vitamin C recording as the most abundant compound, ranging from 1693.5 ppm at 3 months of harvest age to 523 ppm at 6 months of harvest age. Antioxidant compounds came in second, with values ranging from 33.3 ppm at 3 months to 50.9 ppm at 6 months of storage. There were significant (p 0.05) differences in the amount of polyphenol content in rice at various ages. Among the discovered chemicals, chlorogenic acid had the greatest concentration (800.8 ppm) at a harvest age of 3 months. The rice samples included in this investigation contained 26 distinct fatty acid compounds; the most unsaturated fatty acids (33.51%) and least saturated fatty acids (65.7%) were found in rice at 3 months. Significantly more Na and Se were present in the rice at 3 months (97 and 12 ppm, respectively) than at 6 months (67 and 6 ppm). Our research supports the fact that rice samples from the Harir sub-district consist of phytoconstituents and their potential for use as functional foods and in the further development of natural health products.

This paper addresses the diversified needs of urban cold chain distribution and proposes innovative solutions based on storage type multi-temperature co-distribution and mechanical type multi-temperature co-distribution modes. We present an electric vehicle path optimization model aimed at minimizing total costs, taking into account time-varying speed in accordance with urban traffic patterns. Additionally, a genetic algorithm is designed to solve the multi-temperature co-matching optimization path. The study's results reveal that the storage type multi-temperature co-distribution transport mode offers superior economic efficiency, product security, safety, and resource utilization. By comparing and analyzing the results of model solving under different battery capacities, loads, and distributions speeds, the total cost of distribution is optimal when the battery capacity is 120 kWh, the maximum load is 100 kg, and the normal driving speed is 60 km/h. The mechanical multi-temperature co-distribution mode is optimal for the total cost of distribution at a battery capacity of 100 kWh, a maximum load of 100 kg, and a normal driving speed of 50 km/h. The study aims to provide reference significance for logistics companies when making route selection.

This study investigated the effects of adding earthworm mucus on the changes in sludge compost bacterial community structure and its response to environmental factors. The results showed that adding earthworm mucus improved the composting effect of sludge, reducing nitrogen loss and increasing nutrients; nitrogen loss decreased by 5.55%, and potassium and phosphorus increased by 10.23 and 16.28%, respectively. Firmicutes, Chloroflexi, Actinobacteria, and Proteobacteria were the main bacterial phyla in the sludge, with a combined relative abundance of over 60%. The addition of earthworm mucus significantly impacted bacterial community structure and composting activity, increasing the relative abundance of dominant bacteria during the process. Redundancy analysis showed that environmental factors significantly impacted the changes in bacterial community structure during composting. The results indicate that the addition of earthworm mucus increases the relative abundance of advantageous bacteria playing essential roles in sludge composting, enhancing the fertility and maturity of sludge composting products by significantly reducing nitrogen loss and increasing potassium and phosphorus. Based on the response relationship between environmental factors and bacterial communities, the bacterial community structure in sludge composting can be improved by regulating environmental factors (such as pH and moisture content), enhancing the effectiveness of sludge composting.

Water is the most important basic need for sustaining life, and groundwater remains the primary source of this need in the coastal area of Semarang City. This indicates that the recharge of the source must be monitored as an important part of water resource management. Therefore, this study aimed to determine the origin of groundwater through the analysis of stable isotopes 18 O and 2 H, as well as the calculation of the sodium adsorption ratio (SAR) in Semarang City. The purpose is to determine the origin of deep wells and the quality of water for irrigation. The methods used in this study included hydrogeological mapping, testing groundwater samples, and the analysis of stable isotopes 18 O and 2 H. Semarang City was located in an area with geological components, including the Alluvium and Damar Formation, as well as geological structures such as rectification. Chemical parameter testing was carried out by comparing the SAR aspect of 30 samples with their electrical conductivity (EC). From the analysis of stable isotopes 18 O and 2 H, most of the samples were obtained from deep groundwater, while 1 was found in shallow aquifers. Furthermore, the stable isotope composition of 29 samples still followed the Global Meteoric Water Line (GMWL), indicating that they were obtained from global rainwater and had experienced mixing.

The objective of this research was to assess the impact of 2-methyl-2-nitro-3-guanidine on mammalian species, otherwise not the intended targets, followed by one-time exposure and its adverse effects. Thirty-five Sprague Dawley rats of either male or female sex, aged four weeks, and with an average weight of 80±20g, were divided into three groups randomly: control E exposed and exposed and supplemented with vitamin C, and assigned the titles C,E, and V, respectively. Each group comprised fifteen rats. Both E and V groups were further divided into subgroups: E1, E2, and E3, exposed to LD10, LD25, and LD50 doses of Dinotefuran respectively, and V1, V2, and V3, exposed in the same manner but supplemented with a fixed dose of ascorbic acid (vitamin C). Ascorbic acid was administered in aqueous form 35mg/100mL of water and provided ad libitum . Eight hours after exposure to Dinotefuran, 5ml of blood was collected under sedation through the cardiac vein. After 48 hours, two rats randomly selected from each subgroup, including the control group, were anesthetized, euthanized, and dissected. Different body tissues, and the kidney, liver, bones, and heart, were isolated and preserved in formalin solution for subsequent analysis. CBC, liver, renal, and cardiac biomarkers were evaluated. In addition, histopathology and bone characteristics of soft tissues were also conducted. Mortality and morbidity were recorded. The result showed significant disruptions in CBC and other biomarkers related to kidney, liver, and heart in a dose-dependent pattern. Although vitamin supplementation improved the overall outcome, the improvement was not statistically significant. Histopathological examination displayed changes in the exposed (E) group, with no observable improvements with vitamin supplementation. Moreover, the bone-related parameters exhibited similar trends.

There are few studies on the correlation between fertilizer reduction and pesticide reduction in agricultural production. However, exploring the synergy of fertilizer and pesticide reduction (SFPR) is crucial to the comprehensive realization of sustainable agriculture. This study reveals the spatial-temporal evolution patterns of the SFPR in China using the Thiel index and elasticity coefficient methods. The influencing factors of SFPR are empirically based on Synergy Theory. The results show that the proportion of China’s fertilizer reduction is 12.43% and pesticide reduction is 27.32% from 2014 to 2020. That is, the performance of pesticide reduction is more significant in China. And there is a synergistic and positive correlation between fertilizer and pesticide reduction in the provinces of China. The results of the panel data regression model show that the SFPR relies significantly on government policy, financial support, agricultural planting structure, per capita GDP, and agricultural output value. Therefore, this study recommends further strengthening the awareness of responsibility for fertilizer and pesticide reduction at the provincial government and promoting the projects of fertilizer and pesticide reduction via a systematic approach.

Therefore, this study recommends further strengthening the awareness of responsibility for fertilizer and pesticide reduction at the provincial government and promoting the projects of fertilizer and pesticide reduction via a systematic approach.","PeriodicalId":510399,"journal":{"name":"Polish Journal of Environmental Studies","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140717201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing models for land use and land cover (LULC) and monitoring changes through predictive scenarios is crucial for supporting urban development strategies and improving our understanding of urban dynamics. Analysis of urban growth patterns based on LULC data from remote sensing using Geographic Information System (GIS) and Remote Sensing (RS) provides valuable insights into LULC changes. The CA-Markov model was used to predict LULC changes based on maps for 2012 and 2023, derived from satellite imagery using the maximum likelihood method, with an accuracy of 93% and 94% for each map. Analysis of urban growth patterns in Sabang City from 2013 to 2021 shows that the expansion of the built-up area is mainly driven by the conversion of bareland around the city center, with a 67% expansion pattern, 1% infilling pattern, and 16% outlying pattern. In Scenario 1, the growth of the built-up area in the city center is not significant, while in Scenario 2, the built-up area is projected to increase by 32 hectares to 742.6428 hectares by 2032. The urban growth pattern aligns better with Scenario 2, which emphasizes land conservation for forests and water bodies to preserve the highest carbon reserves from LULC changes .
