Leaching behavior and kinetics of beryllium in beryllium-containing sludge (BCS)

Beryllium-containing sludge (BCS) is a byproduct of the physicochemical treatment of beryllium smelting wastewater. The pollutant element beryllium within BCS is highly unstable and extremely toxic, characterized by its small ionic radius and low charge density, resulting in a high risk of leaching and migration. This study is the first to investigate the leaching behavior, influencing mechanisms, and kinetic processes of beryllium in BCS under various environmental conditions. The results indicate that, under national standard conditions, beryllium exhibits a rapid leaching phase within the first 5 h, which then stabilizes after 10 h, with the total leached content significantly exceeding the leaching toxicity identification standards. Under mildly acidic (pH ≤ 5) or highly alkaline (pH = 14) conditions, beryllium demonstrates pronounced leaching and migration behaviors. Notably, in acidic conditions, the leaching rate exceeds 80% within 5 h. Combining the treatment process of beryllium-containing wastewater with analytical methods such as SEM, XPS, ToF-SIMS, and FTIR, it is revealed that due to the heterogeneous nature of BCS, the particle aggregates dissociate over time under acidic conditions. The particle surfaces become increasingly rough, leading to dissolution and the emergence of more reactive sites, resulting in a high proportion of beryllium leaching. Under these conditions, the gradual reaction of Be(OH)2 in BCS to form soluble Be2+ and its hydrolytic complexes is identified as the primary mechanism for extensive beryllium migration. The process encounters minimal diffusion resistance and is classified as reaction-controlled. In acidic conditions with pH = 4, the leaching rate of beryllium significantly increases with rising temperature. The leaching kinetics equation is [(1−x)−0.44]=e(18.26−53050RT)·t, with an apparent activation energy of 53.05 kJ mol−1.

Technical Efficiency and Allocative Efficiency of Beef Cattle Fattening in the Content of Digital Economy: An Empirical Study Based on Survey in China

This study applies data envelopment analysis (DEA) to gauge technical efficiency and allocative efficiency in China’s beef cattle-fattening industry using survey data. The Tobit model considers the salient determinants that drive these efficiencies. The results indicate that (1) large-scale farms exhibit robust TE and pure technical efficiencies (PTE), whereas scale efficiencies (SE) diverge significantly between large and medium-sized operations. The cost efficiency (CE) of smaller farms lags behind their larger counterparts, with the latter displaying greater revenue efficiencies (RE) and profit efficiency (PE). (2) The influence of identical factors on the efficiency of beef cattle fattening production can vary, sometimes antithetically, across different scales. Local policy interventions must be differentiated according to farm type and size. (3) The unique context of China’s national conditions and the status quo of livestock farming render the dual implementation of environmental regulations and technological subsidies less viable for Chinese beef cattle farms. These entities should prioritize production over technological innovation and advancement. Policymakers should adopt strategies such as targeted skill/technological training for farm managers at particular scales of operation. This could represent a critical trajectory to augment the efficiency of beef cattle production and increase beef yield in China.

Comparative View of Marriage Law in the period of Republic of China

The study of comparative marriage law in the Republic of China took the impact of western institutional thoughts as the thrust and the mission of modern national salvation as the gravity. It extensively referenced the marriage and family system of different countries, different traditions and different regions while constantly reflecting on the reform road of domestic marriage and family system. Thus, three views are formed, namely, the theory of overall Westernization, the theory of Respect oneself and be contemptible and treating the condition of the country. Among them, the theory of Respect oneself and be contemptible is deeply criticized by the theory of overall Westernization and the theory of considering national conditions. On the other hand, the theory of overall Westernization and the theory of considering national conditions have their own arguments, and they are interwoven in the comparison of Chinese and Western marriage and family system views and the comparison of specific marriage and family norms. No matter how different their positions are, they are both deeply influenced by Western liberalism and individualism. Therefore, the perspective of comparative marriage law in the Republic of China shows distinct characteristics of The Times, criticism and westernization.

A Comparative Analysis of Low-Carbon Design Strategies for China’s Higher Education Parks Based on Building and Urban Scale in Sustainability Rating Systems

In the global context of carbon neutrality, higher education parks are an important strategic position for achieving China’s goal of carbon peaking and carbon neutralization. Strategies from the perspective of life cycle to guide early low-carbon planning and design are an effective way to achieve carbon emission reduction goals. As the scale of university construction gradually expands, the “urban” attributes of them are becoming prominent. However, there is no quantitative study on analyzing the life cycle carbon emission strategies at both the building and urban scale based on sustainability rating systems. This study first extracts the design strategies according to BREEAM, LEED, DGNB and relative assessment standards for campuses and cities in China at the building and urban scale based on the 7-dimensional low-carbon strategy framework, then sorts out and compares the proportions of carbon-emission-related strategies across various dimensions and life cycle stages. It then summarizes the applications and concerns of low-carbon design strategies at different design scales. Finally, the weighting and calculation methods of life cycle carbon emissions in different sustainability rating systems are compared, the scope and methods of carbon emission benchmarks under different standards are compiled, and the evaluation method for locally applicable carbon emission benchmarks in China is proposed in light of China’s national conditions, which provides guidance for the design process and standard formulation.

Smart specialization of industrial regions of Ukraine: organizational and economic support

Industrial regions of Ukraine, especially near-front territories (Donetsk, Luhansk, Kharkiv and Zaporizhzhia regions), suffered the greatest damage and losses as a result of the full-scale war. The needs for their recovery, according to the joint assessment of international institutions and the Ukrainian government, constitute half (50.46% or $207.2 billion USD) of the reconstruction needs for Ukraine. Considering the structural lag of the economy in industrial regions, dominated by sectors with weak innovation activity and low technological intensity, the continuation of pre-war development trajectories is absolutely unacceptable and non-competitive in the context of the Industry 4.0-5.0 which gains traction globally. In the conditions of a significant change in the profiles of industrial regions due to the war, there is an opportunity to revive their economy but on fundamentally new, innovative principles. Smart specialization can be utilized for this purpose, aiming at the structural transformation of the economy and the development of new competitive advantages for regions and countries. Emphasis is placed on the necessity of conducting a critical analysis and rethinking the implementation directions of smart specialization in the industrial regions of Ukraine. This is due to the varying degrees of consideration of its fundamental principles in the regional development strategies for 2021-2027 and the need for the structural transformation of their economies to overcome the consequences of the war for the local population. The purpose of the article is to identify key problems in the field of organizational and economic support for the implementation of the smart specialization approach in the industrial regions of Ukraine and to determine ways to solve them, taking into account purely Ukrainian challenges and EU experience. The role of organizational and economic support for the implementation of the smart specialization approach in national conditions has been substantiated. The scientific understanding of the main organizational and economic problems and shortcomings of the implementation of the smart specialization approach in the industrial regions of Ukraine has been deepened. It is highlighted that freezing these problems and the absence of appropriate actions to address them will prevent structural and innovation transformations in the economies of regions based on the principles of sustainable development, thereby excluding the possibility of overcoming their structural backwardness. Proposals on ways to solve existing organizational and economic problems are substantiated, taking into account purely Ukrainian challenges, and the knowledge obtained in the EU member states during the implementation of this approach over the last ten years. The practical implementation of these proposals will make it possible to adjust the smart-oriented goals and sectoral focuses of regional development strategies, to direct them to the transformation of the economy of industrial regions through the support of sectors and industries that have the potential to develop new competitive advantages.

Analysis of global liver cancer statistics

Liver cancer is a significant contributor to the world's cancer burden. In order to comprehend the variations in its regional, age, gender, and histological subtype distributions as well as its temporal trend, this paper analyzes the worldwide statistical data of liver cancer, including the incidence, mortality, and survival. The findings indicated that the stages of liver cancer control and prevention are heterogeneous among countries and regions. The successful experience of liver cancer control and prevention in some countries should be promoted and disseminated. According to the various national conditions, comprehensive intervention measures, including reducing aflatoxin exposure, promoting vaccination, improving the treatment of chronic hepatitis infection, and implementing early diagnosis and treatment of liver cancer, should be developed.

The Digital Economy and Agricultural Modernization in China: Measurement, Mechanisms, and Implications

Promoting the progression of agricultural modernization and digital economy integration has introduced new opportunities and challenges for the advancement of China’s agriculture towards high-quality development. Based on panel data from 31 provinces in China from 2011 to 2020, we use the entropy method, coupling coordination model, spatial auto-correlation model, and obstacle model to explore the degree of coupling coordination and influencing factors of China’s digital economy and agricultural modernization. The results show the following. (1) China’s digital economy and agricultural modernization are underdeveloped on the whole, but they show a positive upward trajectory. The digital economy is outpacing the development of agricultural modernization, but the gap between the two is gradually narrowing. (2) The degree of coupling coordination between China’s digital economy and agricultural modernization shows an upward trend. Additionally, there is regional heterogeneity and uneven development of the coupling coordination, i.e., it is high in the eastern region and low in the western region, accompanied by strong spatial agglomeration and correlation. (3) The main obstacle to the progression of the digital economy is digital infrastructure, while the main obstacle to the progression of agricultural modernization is agricultural production capacity. Based on China’s national conditions, we should fully promote the role of the digital economy, explore plans and strategies for promoting the digital economy in differentiated areas, mitigate any imbalanced development, promote the coordinated development of the digital economy and agricultural modernization, and provide decision-making references for the implementation of a digitized China, as well as rural revitalization strategies.

A Study on the Impact of the Scale and Structure of China's fiscal expenditure on people's Livelihood

As a public finance model with Chinese characteristics, people's livelihood finance is rooted in China's current national conditions and development stage. This concept marks a major shift in China's development strategy, from a single fo cus on economic construction in the past to a comprehensive development model that attaches equal importance to economic growth and people's well being. This change not only reflects the country's great attention to people's livelihood issues, but also indicates that China's economy and society are moving towards a new stage that pays more attention to people's livelihood. However, translating ideas into concrete policies and practices does not happen overnight, and requires time to settle and co ntinuous explorati on. Therefore, the key to the construction of people's livelihood finance is to reasonably determine and optimize the scale and structure of financial expenditure in the field of people's livelihood. This paper aims to deeply analyze the current sit uation of China's fiscal expenditure investment in the field of people's livelihood, explore its development trend through empirical an alysis, and reveal the existing problems. Specifically, this paper first makes a quantitative analysis of the scale of China's f iscal livelihood expenditure to reveal its changing trend over time. Then, we will further explore the changes in the expenditure structure, i ncluding the proportion and distribution of investment in key livelihood areas such as education, health care and social security. On this basis, this paper will reveal the existing problems of the current financial expenditure on people's livelihood. In order to deeply analyze the reasons behind these problems, this paper will further explore the main factors that le ad to the scale and structure of fiscal expenditure on people's livelihood. These factors may include unclear policy guidance, imperfect fisc al system, and imperfect supervision mechanism. Through the in depth analysis of these reasons, this paper aims to provide targeted optimization suggestions for the construction of livelihood finance.

Barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating oral health policies in the WHO African region: A scoping review.

To advance oral health policies (OHPs) in the World Health Organization (WHO) African region, barriers to and facilitators for creating, disseminating, implementing, monitoring and evaluating OHPs in the region were examined. Global Health, Embase, PubMed, Public Affairs Information Service Index, ABI/Inform, Web of Science, Academic Search Complete, Scopus, Dissertations Global, Google Scholar, WHO's Institutional Repository for Information Sharing (IRIS), the WHO Noncommunicable Diseases Document Repository and the Regional African Index Medicus and African Journals Online were searched. Technical officers at the WHO Regional Office for Africa were contacted. Research studies and policy documents reporting barriers to and facilitators for OHP in the 47 Member States in the WHO African region published between January 2002 and March 2024 in English, French or Portuguese were included. Frequencies were used to summarize quantitative data, and descriptive content analysis was used to code and classify barrier and facilitator statements. Eighty-eight reports, including 55 research articles and 33 policy documents, were included. The vast majority of the research articles and policy documents were country-specific, but they were lacking for most countries. Frequently mentioned barriers across policy at all stages included financial constraints, a limited and poorly organized workforce, deprioritization of oral health, the absence of health information systems, inadequate integration of oral health services within the overarching health system and limited oral health literacy. Facilitators included a renewed commitment to establishing national OHPs, recognition of a need to diversify the oral health workforce, and an increased understanding of the influence of social determinants of health among oral health care providers. Most countries lack a country-specific body of evidence to assist policymakers in anticipating barriers to and facilitators for OHPs. The barriers and facilitators relevant to disparate subnational, national, and regional conditions and circumstances must be considered to advance the creation, dissemination, implementation, monitoring and evaluation of OHPs in the WHO African region.

Intraoperative ultrasound guided wire (IOUS-wire) localization biopsy with frozen section versus preoperative fine needle aspiration cytology (FNAC) for the evaluation of clinically positive nodes in patients with early breast cancer in China real-world clinical practice.

e12600 Background: Appropriate biopsy procedure for clinically positive (suspicious) lymph nodes (LN) plays a key role in accurate axillary staging of early breast cancer. Fine needle aspiration (FNA) is a recommended method for clinically suspicious nodes in the National Comprehensive Cancer Network (NCCN) guidelines. However, the false negative rate (FNR) of FNA remains too high. Therefore, it is valuable to explore an alternative and appropriate procedure in clinical practice. We conducted a retrospective review to compare the feasibility and diagnostic efficiency of using a novel procedure, the intraoperative ultrasound guided wire (IOUS-wire) localization biopsy with frozen section, to FNA for assessment of clinically positive nodes in patients with early breast cancer. Methods: Data on consecutive primary breast cancer patients with documented axillary ultrasound results who had clinically positive lymph nodes (cN1) between January 2015 and September 2023 either utilization of IOUS-wire localization or ultrasonography-guided fine-needle aspiration cytology (US-FNAC) for clinically positive lymph nodes were retrospectively analyzed. Sentinel lymph node biopsy (SLNB) was performed in patients with negative histopathological or cytological results. The false negative rate (FNR) of histopathology between two groups was calculated. Results: Eligible patients (n=198) referred to axillary biopsy by IOUS-wire localization biopsy(n=100) and US-FNAC(n=98) in this study. The FNR of clinically positive lymph nodes biopsy was 12.8 percent in the IOUS-wire localization group and 87.5 percent in the US-FNAC group.IOUS-wire failed in 5 patients. Among the remaining 32 successful identifications, 26 were IOUS-wire-node positive by intraoperative frozen section. 42 patients with additional lymph node metastases were found in FNAC-LN-negative patients by SLNB. The accuracy rate was respectively 95% and 57.1%. No significant difference was observed in complications and median number of SLNs harvested (5.3 versus 5.5; P=0.631) between the groups. Sufficient tissue samples can be obtained for intraoperative frozen pathology so the FNR is potentially reduced. In addition, the interval of waiting time for pathological results is reduced. Conclusions: Intraoperative US-guided wire localization biopsy is a feasible and alternative procedure compared to preoperative FNA for clinically node-positive patients with early breast cancer. This novel method is suitable for China's national conditions and should be further pursued as a potential biopsy method for evaluation of axillary node status in clinical practice.

The Effect of Local Original Income (PAD), Transfer Funds (Balanced Funds), and Regional Economic Growth on the Regional Poverty Rate of West Nusa Tenggara Province (NTB)

One of the primary goals of any municipality is human development when it comes to regional development. Reducing poverty and improving community welfare and human resources are the primary goals. The poverty rate in NTB Province has dropped dramatically, and the income and economic growth in the area have increased, thanks to the many regional development initiatives that the province has launched. Finding out how local original income, balancing funds, and economic development influence the poverty rate in NTB province is the main objective of this research. Using a battery of tests and regression analysis, we compile a dataset consisting of panel data from ten NTB Province regencies and cities covering the years 2012–2022. The results obtained from this study show that local original funding (PAD) has a significant impact on reducing poverty rates and balancing funds that significantly reduce poverty rates in the NTB province. However, economic growth impacts increasing the poverty rate in NTB province, although not significantly. This may happen because Indonesia's economic growth fluctuates, thus affecting the increase in poverty. Fluctuations occur due to factors such as national economic conditions, supply-demand, government policies, etc. This can affect the economic growth of NTB, and it also impacts the increasing poverty rate in NTB. In addition, the increasing population is one of the factors that contribute to economic fluctuations and the increase of poor people in NTB.

Does the community service environment affect the willingness of older adults people to socialize for older adults care?

Population ageing is a significant trend in social development and will remain a fundamental national condition in China for the foreseeable future. Socialized older adults care has become a crucial strategy for China to address population ageing. However, the current levels of acceptance and willingness to seek socialized older adults care among older adults are relatively low. This study focuses on examining how the community environment and services influence older adults people's willingness to engage in social activities related to older adults care. Using data from the China Longitudinal Ageing Social Survey (CLASS) (N = 9,657), this study investigated the impact of the community service environment on older adults people's willingness to participate in social activities related to older adults care through a logit model. The study revealed that 9.15% of older adults (N = 9,657) in China are willing to engage in social activities related to older adults care. Furthermore, the individual characteristics and family support of older adults play a significant role in shaping their willingness to engage in older adults care. The provision of medical services, daily care services, and entertainment venues by the community positively influence older adults people's willingness to participate in social activities related to older adults care (p < 0.01), whereas psychological counselling services have a negative impact (p < 0.01). The impact of community services on older adults people's willingness to engage in social activities related to older adults care varies due to factors such as smoking and chronic diseases. These findings provide valuable insights for improving older adults' social engagement in China.

Political connections and corporate ESG performance

With the popularization of the concept of sustainable development, corporate ESG performance has attracted more and more attention from all walks of life. However, there is still a lack of in-depth discussion on what factors affect corporate ESG performance, especially in a political and economic system like China. This article takes A-share listed companies as a sample to empirically analyze the impact of political connections on corporate ESG performance. The study found that political connections can promote corporate ESG performance by increasing media attention and reducing financing constraints. Further research found that this promotion performance is more significant in non-state-owned enterprises. This article combines the national conditions with Chinese characteristics, enriches the research on the factors that promote corporate ESG performance from the government perspective, and deepens the research on the role and consequences of political connections.

China's Response to Capital Market Liberalization

Looking back at the Asian financial crisis of that year, although the outbreak of the crisis is closely related to the Asian countries' own inherent defects in institutional mechanisms, it is also related to the opening of the capital market, but the opening of the capital market is not an important factor that led to the financial crisis in China, so China should not close the capital market, but rather should be free to open up the scenarios, and the content of my research is to explore the Chinese response to the issue of the opening of the capital market. Through analysis, this paper argues that China cannot face the opening of the capital market overnight; it still needs to carefully consider the opening of the capital market and take many factors into account. It should be gradual rather than faster, and a more thorough opening up is better. To make a comprehensive judgment on the opening up of the capital and financial markets in the light of China's current national conditions. The following aspects should be considered: keep an eye on China's real economy situation and launch more pragmatic initiatives; strengthen the risk prevention capability; improve the various mechanisms of the capital market.

Comparison of comprehensive evaluation’s and unified examination’s effectiveness in university enrolment: Chinese evidence from propensity score matching analysis

ABSTRACT Against the backdrop of global transformations in university admission systems, the quest for an enrolment paradigm that efficiently identifies and selects high-quality students has gained paramount significance. With the help of propensity score matching (PSM), this study controlled students’ backgrounds and compared the performance of students admitted to the university by comprehensive evaluation and by unified examination. The results of this investigation find that there was no significant difference in professional identity, academic performance, and career competence between the two groups of students. However, compared with students admitted by comprehensive evaluation, students who were admitted by unified examination were more inclined to use deep learning strategies. Based on these findings, this research suggested that countries and universities around the world should pay more attention to unified examination when selecting students, and the reform of university enrolment should fully consider the national conditions and seek progress while maintaining stability.

An empirical examination of liability for ecological environment restoration in the context of the Civil Code of China

In environmental tort lawsuits, China has been overly focused on “punishing” violators and has neglected the value of ecological environment restoration. The Article 1234 of Civil Code of China in 2021 has provided an important institutional guideline for the restoration of ecological environment and sustainable development in China. This paper analyzes 512 cases of ecological environment restoration liability and identifies five challenges in the judicial context: the lack of sound legal regulation, the lack of liability allocation, the mismatch of liability subjects, the difficulty of identifying damage facts, and the difficulty of effective implementation of restoration. In the face of these difficulties, countries that attach importance to ecological environment restoration, such as the United States, Germany and Japan, have provided experience that can be drawn on for China's ecological environment restoration liability. Based on foreign experience, China's liability for ecological environment restoration should be improved in the following aspects: first, to improve the legal system from basic laws and specific laws; second, to expand the scope of subjects from both litigation request subjects and liability subjects; third, to improve the identification and assessment mechanism and innovate the identification and assessment procedures in accordance with China's national conditions; fourth, to determine the restoration methods based on the criterion of “utilization value and the differences in the objects. The ultimate goal is to help China's Civil Code to be better applied judicially on the one hand, and to contribute to the world ecological protection on the other.

Impact of the Development of a Low-Carbon Economy on Global International Trade

With the continuous development of human society, the high intensity of energy use has caused serious damage to the environment. Due to the aggravation of ecological problems, governments have gradually set their eyes on balancing economic development and environmental protection. In this context, the "low-carbon economy" emerged and became the keyword in the new policies introduced by governments around the world. However, along with the introduction of low-carbon policies in various countries, its significant impact on international trade has also begun to emerge. Due to the different national conditions and backgrounds of various countries, how to develop a low-carbon economy and how to develop international trade under the background of a low-carbon economy has become one of the key research topics of all countries in the world. By discussing the development of a low-carbon economy and its relationship with international trade, a feasible new strategy of international trade development under the background of low low-carbon economy is proposed.

Air Handwriting using AI and ML

Air-writing refers to virtually writing linguistic characters through hand gestures in three dimensional space with six degrees of freedom. In this paper a generic video camera dependent convolutional neural network (CNN) based air-writing framework has been proposed. Gestures are performed using a marker of fixed color in front of a generic video camera followed by color based segmentation to identify the marker and track the trajectory of marker tip. A pre-trained CNN is then used to classify the gesture. The recognition accuracy is further improved using transfer learning with the newly acquired data. The performance of the system varies greatly on the illumi nation condition due to color based segmentation. In a less fluctuating illumination condition the system is able to recognize isolated unistroke numerals of multiple languages. The proposed framework achieved 97.7recognition rate in person inde pendent evaluation over English, Bengali and Devanagari numerals, respectively. Object tracking is considered as an important task within the field of Computer Vision. The invention of faster computers, availability of inexpensive and good quality video cameras and demands of automated video analysis has given popularity to object tracking techniques. Generally, video analysis procedure has three major steps: firstly, detecting of the object, secondly tracking its movement from frame to frame and lastly analysing the behaviour of that object. For object tracking, four different issues are taken into account; selection of suitable object representation, feature selection for tracking, object detection and object tracking. In real world, Object tracking algorithms are the primarily part of different applications such as: automatic surveillance, video indexing and vehicle navigation etc. The generated text can also be used for various purposes, such as sending messages, emails, etc. It will be a powerful means of communication for the deaf. It is an effective communication method that reduces mobile and laptop usage by eliminating the need to write. Key Words: Air Writing, Character Recognition, Object Detection, Real-Time Gesture Control System, Computer Vision , Hand tracking.

Inspiration and Innovation of Informal Economic Governance under Socialism with Chinese Characteristics: Reconstruction of Street Vendor Governance Model in Fuyang City

Vallholder economy is an important driving force for urban economic and social development in the new era. Under the background of socialism with Chinese characteristics, through comparative research, empirical research, investigation and analysis, this paper concluded that the street vendor economy is informal, long-term and complex. For the governance of Chinese street vendors, we should learn from the theory, absorb foreign experience based on the national conditions and urban status, and find the breakthrough of governance from the root. Formulate “flexible” flexible policies, optimize space politics, divide and rule, break through the constraints of regularization, reconstruct and innovate the economic governance model of Chinese street vendors, and realize the “Sinicization of governance concept, local governance policy and contemporary governance model”. The research has enlightenment and reference significance for enriching the development of political economy theory, innovating the informal economic governance model and developing the informal economy in the new era.
